All am3 processors. Processors suitable for socket am3 and am4

They appeared in 2009, and differed from their predecessor, Socket AM2+, by supporting DDR3 memory and a higher speed of the HyperTransport bus. Processors with this socket, to ensure compatibility with previous generation motherboards, also supported DDR2 memory. See the laconic

Socket AM3+

Socket AM3

In 2011, AM3+ appeared, the main difference of which was its support for the new AMD Bulldozer microarchitecture. compatible with AM3 processors, but vice versa, that is, they cannot be installed, with very rare exceptions. This is due to the fact that the diameter of the holes for the leads exceeds the diameter of the holes for the leads of processors with Socket AM3 - 0.51 mm versus the previous 0.45 mm.

Let's compare the characteristics of the cores of older processors on this socket. They are Vishera for Socket AM3+ and Thuban for Socket AM3.

Unlike most other processors with different sockets, AMD solutions usually work with the same chipsets. For example, they work great with AMD 760G, 880G and 990G chipsets. For this reason, it makes no sense to compare them. Here are the characteristics of the chipsets latest generation.

Let's compare the performance of older models (AMD Phenom II X6 1100T) and AM3+ (AMD FX-9590). To measure performance, we used our standard methodology. Results in the table:

As is usually the case, new processor shows noticeably better results in all tests. This is predictable, since the processor has large quantity cores, higher frequency and larger L2 and L3 cache. The only strange thing is the Linpack test, during which a system of 1000 is solved linear equations. After discovering this strange result three repeated measurements were taken, but the results remained approximately the same. Based on this, we conclude that if the computer is used for mathematical calculations, then the transition from AM3 to AM3+ processors does not make sense. For all other tasks, a more modern processor is suitable.

Let's turn to the power consumption of these processors. And just looking at the specifications, it becomes clear that a processor with socket AM3 will be much more economical. The Phenom II X6 1100T has a stated TDP of 125 W, while the FX-9590 has a stated TDP of 220 W. Yes, we were not mistaken, exactly 220W. In practice, the power consumption of the stand, with maximum load on the processor and almost complete inactivity of the video card, is as follows:

As you can see, for high performance fast processors come at a cost, and this is not only, or even not so much, electricity bills, but more expensive cooling systems and motherboards that can supply these processors with energy. Of course, not all of them have such high energy consumption; most of them require power similar to the previous generation. True, the performance is still higher than that of older CPUs.

AMD Socket AM3/AM3+ processors buy in Moscow by minimum prices available at the Sales Center computer equipment ENKO, where they are available in a wide range.

AMD Socket AM3/AM3+ processors

Modern AMD processors They compete with their analogues from Intel and are widely represented in the assortment of our online store. Technical AMD specifications Socket AM3+ and Socket AM3 make them a worthy choice for building on them personal computers of varying performance, from budget office ones to sophisticated gaming ones. These processors are in fairly high demand also because their cost is relatively low.

Main characteristics of AMD Socket AM3 and AM3+

The line of processors designed for installation in Socket AM3 includes Sempron, Athlon II, and many Phenom II models. All of them use the Hypertransport 3.x bus and have 938 pins. In principle, it would be wrong to say that there are any significant differences between AMD Socket AM3 and AM3+. In fact, AM+ processors are simply a further logical development of AM processors. They only differ individual features his interior architecture, which are well known only to specialists. It should be noted that the compatibility of AMD Socket AM3/AM3+ processors is incomplete: AM3 CPUs fully correspond to the AM3+ motherboard socket, both mechanically and electrically. AM3+ processors correspond to AM motherboards only mechanically - for their correct operation in this socket, the AM3 motherboard requires BIOS flashing, but some processor functions will be limited, such as power saving.


Socket AM3+ processors are known as the AMD FX series. The processor architecture is called Bulldozer and Piledriver. They correspond to kernels codenamed Zambezi and Vishera. The latest core has AMD Turbo Core technology - dynamic overclocking of the processor frequency depending on the load. Regarding this important parameter, as performance, then eight-core top processors AMD FX Black

Edition with the Vishera core overclocks well and competes with the INTEL Core-i7 at a significantly lower price. The price of AMD Socket AM3 plus in Moscow is now quite acceptable, and therefore gaming computers, built on the basis of these processors, are appearing more and more.

Advantages of purchasing AMD Socket AM3/AM3+ processors in our online store Both budget and high-performance AMD Socket AM3 AM3+ processors can now be purchased from many companies, but it is best to do this at the ENKO Computer Equipment Sales Center. The fact is that we present them:

Receive comprehensive advice before purchasing. The ENKO computer equipment sales center has extensive practical experience in assembling computers. AMD AM3 and AM3+ processors are ideal for creating low-cost office platforms, universal home computers or powerful gaming machines.

In our company AMD price Socket AM3+ and AM3 are one of the lowest in the capital, which is well known to numerous regular customers. All these processors are provided with a full warranty, which, however, as practice shows, you never have to use.

AMD Socket AM3 | Introduction

The position of catching up is a serious motive to start releasing products that differ (hopefully for the better) from the competitor. For AMD, this resulted in an attempt to develop a smooth and seamless transition from one platform to another.

X3: The number after X means the number of cores that are active in the processor. The X3s are built on the same chip as the quad-core X4 processors, but only three cores can be used.

720 : This is where things get complicated. The first digit indicates belonging to the general class. The AMD 900 line contains full-fledged Phenom II processors with four active cores and 6 MB of L3 cache. The 800 line also consists of quad-core processors, but they are equipped with a smaller L3 cache: 4 MB instead of 6 MB. The 700 line starts with the high-end X3 models, which also feature 6MB of cache. We're guessing this leaves room for a 600 line that could feature three cores and 4MB of L3 cache, but we're still guessing.

The second two digits indicate the clock speed. Unfortunately, AMD does not seem to have any formula that would allow us to calculate a specific frequency. So, the 940 processor operates at 3 GHz. The 920 and 720 processors are both 2.8 GHz. But all CPUs 910, 810 and 710 operate at 2.6 GHz. That is, the idea that each increase in the number by 10 corresponds to an increase of 100 MHz is incorrect. 805 processors have a frequency of 2.5 GHz.

Finally, there are Phenom II versions Black Edition, on this moment these are the X4 940 and X3 720, which have an unlocked multiplier, which makes it easier to overclock the CPU.



As we can see, such a naming convention, which is universal for the entire new Phenom II line, can confuse buyers. So, by the name of the processor you cannot distinguish the Phenom II only for AM2/AM2+ (X4 940/920) from the new variants for AM3. Moreover, enthusiasts who want to upgrade to AM3 with DDR3 support will have to buy a processor in the middle of the AMD Phenom II line, since flagship models limited to the old socket.

We discussed the lack of high-end AM3 models with AMD representatives, and came to the following conclusion: AMD does not expect many enthusiasts to immediately rush to buy AM3 motherboards and processors. Instead, the company is leaning into the upgrade market, where many users will want to install new chips into existing AM2/AM2+ motherboards. Therefore, at the launch of AM3 processors, models were introduced that provided best ratio performance/price. We should probably expect the release of high-end AM3 processors soon.

AMD Socket AM3 | Prices

We don't have pricing for the full line of AM3 processors, but AMD has indicated that the Phenom II X4 810 will retail for $175 and the Phenom II X3 720 Black Edition will retail for $145.

Conversations with motherboard manufacturers also shed light on the situation: motherboards for AM3 will cost at the same level as previous AM2/AM2+ models. The Asus M4A79 Deluxe, a Socket AM2+ motherboard with an AMD 790GX/SB750 chipset combination, sells for around $200 today. The M4A79T Deluxe, a replacement for the old Socket AM3 model with the same platform, will also sell for $200, according to Asus.

It should also be noted that the AMD Phenom II X4 940 Black Edition and 920 processors have already dropped in price compared to when they were announced in early January. The 3GHz 940 is now $225, and the 2.8GHz 920 is now $195 in quantities of 1,000. The consequences are quite significant, since initially the fastest AMD Phenom II was close in price to Intel Core Entry-level i7.

AMD Socket AM3 | Processor details

All AMD Phenom II processors for AM3 are very similar to the existing AM2/AM2+ Phenom II chips.


Socket AM2+ on the Asus M3A79-T motherboard. Click on the picture to enlarge.

Each core uses 64 KB of L1 data cache and 64 KB of L1 instruction cache, giving 128 KB per core or 512 KB for a 4-core processor. Each core also has 512 KB of L2 cache, which is 2 MB for X4 processors and 1.5 MB for X3 processors. Then, depending on the model, you get 4 or 6 MB of shared L3 cache.

The processor's memory controller is what makes the difference between the current Phenom II and those models that were presented during CES 2009. The 128-bit controller remains the same in width, it works with two 64-bit memory channels. But if the previous Phenom II memory controller operated at 1.8 GHz, then all AM3 processors support it at frequencies up to 2 GHz. AM3 expands memory support to DDR3-1333 mode, in addition to the DDR2-1066 ceiling of the previous generation. What's interesting is that if you choose DDR3-1333 modules, you'll be limited to one DIMM per channel, so memory choice becomes quite critical.

To increase the frequency of the memory controller, you can add a faster HyperTransport interface: its operating frequency has also increased from 1.8 GHz to 2 GHz, which has shifted the theoretical ceiling bandwidth from 31.5 GB/s to 33.1 GB/s.

AM3-enabled Phenom II processors are manufactured using AMD's 45nm DSL SOI process and contain approximately 758 million transistors on a 258 square millimeter die area, meaning the new CPUs are built on the same die as the existing Phenom II X4 940/920. The difference, of course, lies in the socket. Due to 940 pins, you cannot install older AM2/AM2+ processors in new socket AM3. Officially, AMD claims that it will release faster processors in the near future. But we didn’t wait, so we also tested the high-speed Phenom II AM2+ on the new socket, biting off two legs.

Phenom II processors have come a long way in trying to improve their power consumption compared to Intel models. First and foremost, the Phenom II design allows for four p-states rather than just two. As a result, in idle mode, the Phenom II chips in our initial review reduced frequencies down to 800 MHz. Power consumption was also reduced significantly, and AMD's new design actually turned out to be more power efficient than the previous one.

At the same time, AMD changed the power saving mechanism, which allowed each core to independently enter the p-state. If a thread starts running on the core at half the frequency, then performance suffers because of this. Now, with Phenom II processors, all four (or three) cores run at the same frequencies. But increasing the number of p-states allows us to achieve a much better balance between frequency and energy savings.

The last Phenom chip in AMD's lineup was the Phenom X4 9950 Black Edition at 2.6 GHz. This processor had a TDP of 140 W, which caused problems when installed on some inexpensive motherboards not designed for such loads. The move to 45nm has helped AMD reduce heat dissipation in its Phenom II processors, and the 3GHz X4 940 has a TDP of 125W. All other AM3 chips turn out to be even more economical, given their 95 W TDP.

AMD Socket AM3 | Modding

Our first thought when we learned of AMD's refusal to release Phenom II X4 940/920 equivalents for the AM3 platform was: "What about all those enthusiasts who have their eye on high-end models and want to experiment with DDR3 memory?"

Unfortunately, our Phenom II X4 940 did not overclock very well, we planned to replace it with another chip with great potential, so we decided to use the sample to "create" a 938-pin AM3 chip from our 940-pin AM2+ sample. After all, the silicon chip inside is the same, and the only difference lies in the interface.

So, using a mechanical pencil, we bent the legs back and forth until they broke off. Now the chip could physically fit into the AM3 platform, although it did not fit completely into the socket due to the metal protrusions where the broken legs were located. Unfortunately, the processor modified in this way did not boot into POST at all, so we came to the conclusion that the problem was not just two legs. It's a shame that enthusiasts can't access an AMD AM2 pin layout that can describe the exact role of each pin without forcing us to guess. Last technical documentation, available publicly, concerns the good old Socket 940 interface.

We were wondering if we had burned out the new processor. So we switched the Phenom II X4 940 back to an AM2+ motherboard. Interestingly, it worked perfectly without any problems.

AMD Socket AM3 | Overclocking

Since our efforts to turn flagship processor AMD Phenom II compatible with Socket AM3 was not successful, we decided to try the Phenom II X3 720 Black Edition. AMD told us that the Phenom II X3 should, in theory, respond better to overclocking because the processor is less complex than quad-core models.

Indeed, with the help of the Asus M4A79T Deluxe motherboard we immediately got it working triple core chip 150 MHz faster than our X4 940 sample, reaching 3.8 GHz.

At $145, this looks like a great option for enthusiasts who have already purchased a 790 family motherboard with DDR2 memory. Even the Core 2 Duo E8500, the results of which we presented in this article, still costs $190. The Phenom II X3 will run faster in applications optimized for more than two cores, and it will perform well in comparison with the Intel Core 2 line after overclocking.

AMD Socket AM3 | Test results

AMD Socket AM3 | Synthetic tests



We'll start looking at the results with the SiSoftware Sandra tests, since memory bandwidth is quite interesting when moving to a new platform like this. All AM2+ configurations use the same DDR2-1066 modules, although we do see some differences between the slowest Phenom X3 8750 and the fastest Phenom II X4 940. As expected, the Core i7 three-channel memory controller significantly increases memory bandwidth, although our engineering sample was locked in DDR3-1066 mode. Retail Core processors i7 do not have such a limitation; they can set a larger range of memory multipliers.

AMD has warned us that the current generation of AM3 motherboards are not yet optimized. But this cannot be said if you look at the memory bandwidth results, which show that the AM3 platform was able to provide more than 13 GB/s. Let us remind you again that DDR3-1333 is the fastest memory mode supported by the built-in controller AMD memory. However, Asus decided to add DDR3-1600 mode to Motherboard BIOS M4A79T Deluxe boards.



If we look at the results of 3DMark Vantage, then it is better to take the measurement test CPU performance. Here we see a significant lead from the Intel Core i7 920 at 2.66 GHz, followed by the fastest processor in the Phenom II line, the X4 940. In the other two tests, however, the Core i7 comes in last.




Test PCMark package Vantage is filled with a variety of scenarios where the Intel Core i7 shines, so we're not surprised to see the entry-level 920 take the lead. However, Phenom II X4 is also very close to it. The X4 810 for Socket AM3 beats our simulated X4 910, despite having 2 MB less L3 cache - good sign support for DDR3 memory on the new platform.

AMD Socket AM3 | Applications

Intel is the leader in the 3ds Max test, and the gap is quite significant. Considering this test is optimized for multi-threading, it is not surprising that the AMD Phenom II X4 940 comes in second place, followed by other quad-core AMD models. The triple-core X3 720 is on par with the dual-core Intel E8500. At the same time, the old X3 8750 is inferior to the dual-core chip.

Another test with good multithreading support. WinRAR gives the 2.6 GHz Phenom II X4 810 an advantage over the tri-core X3 720 BE, despite the X3's clock lead. Interestingly, the X4 810 again outperforms the simulated X4 910, despite having a 2MB smaller L3 cache. Considering that the only difference in the two configurations is the 1333 MHz DDR3 memory, we have to give more credit modern technology memory.

WinZip can use no more than two cores, so the 2.8 GHz X3 was faster than the 2.6 GHz X4 810 (not to mention the fact that the 3.16 GHz Core 2 Duo beat all other processors tested).

Our AVG test benefits from quad-core processors. Intel Core i7 has a significant lead, and AMD's quad-core processors are grouped together at a slight distance. Then we see the X3 processors, with the dual-core Core 2 Duo E8500 finishing last.

AMD Socket AM3 | Audio/video encoding

Audio/video tests tend to favor Intel processors Core i7. Starting from the Mainconcept, the i7 920 quickly shows its strength, being the fastest processor in our testing. However, AMD quad-core processors also show themselves worthy. The Phenom II X4 940 finishes the test in 2 minutes 15 seconds, the X4 810 is 16 seconds behind (slightly ahead of the simulated 910). The AMD Phenom X3 720 BE improves the result of the X3 8750, but this is due not only to the frequencies, but also to the large cache size.

Intel dominates TMPGEnc once again. The scaling of AMD processors is approximately the same as Mainconcept when choosing the DivX codec. However, Xvid shows how the 2.8GHz Phenom II X3 720 was able to beat many quad-core chips because it doesn't scale as well to four threads. In the Windows Task Manager, we found that the Xvid test puts the X3 at about 30% CPU load.

We have another test that is more sensitive to clock speed than to the number of threads. At Lame, the Phenom II X3 delivers more impressive results than most quad-core processors in AMD's portfolio.

The same situation is observed in the iTunes test.

AMD Socket AM3 | Games


Playing Crysis puts a lot of stress on the graphics card, so we don't see much impact on processing power until you get down to the level of the Phenom X3 8750, which is a bit of a drag on performance at 1920x1200. Enabling anisotropic filtering and anti-aliasing reduces lag to 1 fps, shifting the performance focus even more to our single GeForce GTX 280.


Far Cry 2 isn't as demanding as Crysis, and we actually get acceptable frame rates up to 2560x1600 resolution. But, as we see, performance depends little on the processor in our test platform. This time the Intel Core i7 920 performs poorly, the performance of this system was worse than that of the AMD Phenom X3 8750.


The Intel Core i7 920 still needs to be overclocked to perform well in a gaming computer. We again observe that systems based on it are inferior to AMD computers. Interestingly, the Phenom II X3 720 BE was able to beat the flagship X4 940 in a couple of cases, despite being 200 MHz behind. However, the fastest of all Phenom processors was the Intel Core 2 Duo E8500 with a frequency of 3.16 GHz.


We all know that Call of Duty game supports multi-threading, so it scales well on AMD quad-core processors. But the lag of the tri-core X3 720 processor from the X3 8750 in a resolution of 1920x1200 with anti-aliasing is quite difficult to explain, given the advantages of the new chip in terms of frequencies and cache size.

AMD Socket AM3 | Energy consumption



Click on the picture to enlarge.

The power consumption graph above was obtained from a full run of PCMark Vantage on six of the eight processors we tested. Even excluding the two CPU models, the graph is quite interesting.

We ran all of the tests in our review with each processor's power consumption features turned on. Previously, we were wary of this, since activating features such as Cool"n"Quiet and EIST somewhat reduced performance. However, this scenario is still closer to real conditions, in which users work.

Even without jumping to the average power consumption and total power consumption, it is clear that the Phenom II X4 810 with 4 MB L3 cache and DDR3 memory uses less power when idle. The simulated Phenom II X4 910, shown with a black line, consumes significantly more power, which means that we can assume a noticeable increase in power efficiency when moving to the DDR3 platform (however, in this case Some of the difference can be attributed to the different size L3 cache).

After calculating the results, we got the following.

Phenom II X4 810 Phenom II X4 910 (sim.) Phenom X4 9950 BE Phenom X3 8750 Core 2 Duo E8500 Core i7 920
Average power consumption (W) 157,59 172,63 191,66 196,80 161,08 195,95
Test run time 59:57 1:10:45 59:55 1:00:38 55:29 58:28
Total Energy Consumption (Wh) 157,46 203,56 191,40 198,87 148,95 190,94

One of the most low values average power consumption and the shortest test run time lead to the leadership of the Intel Core 2 Duo E8500, but it is closely followed by new AMD Phenom II X4 810. The simulated Phenom II X4 performed well in terms of average power consumption, but the run took a long time, so the total amount of energy consumed is not so encouraging. However, most of the time your computer will be in idle mode with the Phenom II processors running at 800 MHz, so power consumption will not be as great.

AMD Socket AM3 | Conclusion

Our article discusses two new components. The first is the new three- and four-core AMD Phenom II processors. The second is the Asus M4A79T motherboard for Socket AM3.

Putting aside Socket AM3 for a moment, the new Phenom IIs primarily fill out and refresh AMD's 45nm lineup. Since they can be installed on AM2/AM2+ motherboards, you can safely ignore the 938 pins, and AMD can be thanked for filling the mid- and entry-level markets with Phenom processors equipped with large caches, running at more high frequencies, and also featuring improved scalability.

However, the AM3 interface also needs to be taken into account. AMD does not yet believe that the Phenom II plus DDR3 memory combination is completely ready. While we've seen some pretty decent increases in memory bandwidth when moving from DDR2 to DDR3, the increase doesn't always translate into more. real applications. In any case, the test results speak in favor of DDR3. In fact, in most cases the Phenom II X4 810 (2.6 GHz processor with the L3 cache cut to 4 MB) was able to outperform our simulated Phenom II X4 910 with full size 6 MB cache. Moreover, during power consumption tests we received evidence that the Phenom II and DDR3 memory together provide one of the most efficient platforms (in terms of performance per watt) that we have ever seen in our laboratory.

With that said, to upgrade to AM3 you'll need one of the Phenom II processors announced today. You will also need a motherboard such as the Asus M4A79T Deluxe with Socket AM3 interface. And you'll need DDR3 memory, which still costs significantly more than DDR2. Given the lack of tangible performance gains, even with increased power efficiency, switching to the full AM3 platform makes no sense today, which is not surprising.

What makes more sense is installing the Phenom II X3 720 Black Edition on existing platforms AM2/AM2+, equipped inexpensive memory DDR2. Gone are the days when Core 2 Duo processors dominated the market for gamers trying to build optimal system in terms of price/quality ratio. Now AMD has worthily entered this market, and three cores, which previously seemed ridiculous, give their advantage.

Socket AMZ - processor socket, developed by AMD for desktop processors high-performance, mainstream and budget segments. Is further development Socket AM2+, the differences are support for DDR-III memory and higher speed of the HyperTransport bus. The first processors using this socket - AMD Phenom IIХ4 910, 810, 805 and AMD Phenom IIХЗ 720 and 710 were released in February 2009.

Socket AMZ processors have a memory controller that supports both DDR-II and DDR-III. therefore, they can work in Socket AM2+ boards (the performance of a specific processor in a specific board must be checked using the CPU Support List on the motherboard manufacturer’s website), but the reverse situation is impossible. Socket LM2 and Socket AM2+ processors in Socket AMZ boards do not work. This is related to that. that AMZ processors will have a new memory controller that simultaneously supports DDR2 memory. and DDR3 memory, thus providing backward compatibility with AM2 motherboards, but since AM2 processors do not have a new memory controller, they will not be able to work on motherboards AMZ.

Boards with Socket AMZ support only DDR-III memory with frequencies from 800 to 1333 MHz, both unbuffered (regular) and with ECC. The memory organization is the same as in Socket939/940/AM2/1156, i.e. dual-channel, and To achieve optimal performance, it is necessary to install two or four (preferably identical in pairs) memory modules in accordance with the instructions for the motherboard.

And finally. Socket AMZ+ is a new processor socket for motherboards that is mechanically and electrically compatible with Socket AMZ (despite a little larger number contacts - 942. Also in some sources it may be called Socket AMZ). but designed to support new AMD processors on the Zambezi core based on the Bulldozer architecture like the AMD FX 8150. All old Socket AMZ processors are also supported by it, and, naturally, such boards only work with DDR3 memory and are compatible with previous Socket AM2/AMZ coolers.

AM3+ connector

There is information that Socket AM3+ processors will not be compatible with Socket AMZ boards. primarily due to the larger diameter of the processor legs. A board based on an old chipset that will be able to support Socket AMZ+ processors after BIOS updates, it will be possible to differ in the characteristic black color of the socket, but in such boards some of the processor functionality related to power saving and monitoring may be lost. This information may be updated in the future.

The next connector, Socket AMZ+, is a modification of Socket AMZ. designed for processors codenamed Zambezi, which will use the new Bulldozer micro-architecture.

On some motherboards with the AMZ socket, it will be possible to update the BIOS and use processors with the AMZ+ socket. Please note that there are significant limitations on compatibility with previous sockets. So. when using processors AMZ+ on motherboards with AMZ. It may not be possible to obtain data from the temperature sensor on the processor. Also, the power saving mode may not work due to lack of support fast switching core voltage in Socket AMZ.

The AMZ+ socket on motherboards is black, while AMZ is white It can also be recognized by the “AMZ+” marking.

The diameter of the holes for the outputs of processors with Socket AMZ+ exceeds the diameter of the holes for the outputs of processors with Socket AMZ - 0.51 mm versus the previous 0.45 mm.

Since June 2011, deliveries of serial processors in the Socket AMZ+ version began. One of the first motherboards to go on sale was the 890GM Pro3 K2.0 motherboard from ASRock. which combines the AMD 890GX + SB850" combination with the Socket AMZ+ processor socket (Fig. 2). This motherboard Micro format ATX is ready to work with 8-core processors in the Socket AMZ+ version (Socket AMZL), and compatibility with existing processors in the Socket AMZ version is also maintained.

Hello, readers of my blog about hardware. In this article I wanted to look at which processors are suitable for the am3 and am3+ sockets. Despite the fact that this connector from AMD came out more than 7 years ago, it is still in demand on the market, since the release of new chips for AM4 has greatly reduced the prices of FX-8xxx, which, moreover, are also very popular.

If you want to find out which processors are suitable for 1151, here we will look at supported products that can be installed in socket am3+. We will also briefly touch on some characteristics of chips, such as the highest-performance FX-9590 and the popular FX-8300.

List of supported chips

If you look at the official statistics, AM3+ in theory is not compatible with AM3, but older chips work great on a newer socket, without any hardware restrictions in terms of overclocking. The table will include both new and old CPU models, among which you will probably find best processor for games.

Vishera (32 nm):

Bulldozer (32 nm):
As you can see, the FX generation has 2 incarnations, which include 2 architectures, with Vishera being a modified and improved version of Bulldozer. Both options will run smoothly on any motherboard.

Models for AM3 are also suitable for AM3+.

Their lineup looks like this:
Which processor for your PC? Try to look for the most “fresh” solution, i.e. AMD FX. Let's say right away that the 4-core FX-4100 is not the most the best choice to create a system, since there are more advanced FX-8xxx, in particular 8300, which can easily reach 4.8 GHz on the 970 chipset using cooling, the level of Zalman CNPS10 Optima or Deepcool Gammaxx 300.

You can still find new chips on sale at very attractive prices and we recommend purchasing OEM versions, since they are cheaper than BOX, and are in no way inferior in characteristics. you can read about the main differences between BOX and OEM.

A few words about AM4

In 2016, a completely new processor socket for AMD Ryzen processors, AM4, was introduced to the market. Unlike previous options (AM3+, AM3, AM2+, AM2), this socket is completely new and is not backward compatible with obsolete processors from the red ones. However, it supports much more interesting chips that are relevant at the time of 2018:
The list includes models based on the Zen and Zen+ architecture, which are backward compatible with each other and work perfectly on motherboards with A320, B350, B450, X370 and X470 chipsets.

Optimal models

If you need the most balanced processor of the AM3+ family, we recommend taking a closer look at the already mentioned FX-8320 with a base frequency of 3.5 GHz, which can be used without special problems raise to 4v Turbo Boost, or manually turn it up to 4.5, if there is good cooling.

Do you have a board based on the top-end 990FX chipset? Try the FX-9590, which operates at 4.7 GHz in stock and can push up to 5 GHz, but under one condition - a 220 W thermal package. And this indicates the very “hot” nature of the chip.

And now as for modern models on AM4. The best solution for an entry-level multimedia system, there will be Ryzen 5 2400G with built-in Vega 11 video core, whose performance is comparable to GeForce 1030 GT
As universal solution we want to offer Ryzen 5 1600, which has 6 cores and 12 threads, as well as a low thermal package of 65 W and an excellent performance margin. This stone will provide maximum immersion in any game or program.
