List of Top 10 Best AM3+ CPU
AMD FX-8350 Black Edition is no doubt the king of AM3+ CPU, as it provided high performance while not being as expensive as the flagship processors. As for the specifications of the processor are concerned, it is an octa-core processor, i.e. providing eight cores and eight threads which means that this processor predates the SMT technology which is similar to the Hyperthreading technology from Intel, allowing the processor to have twice the amount of threads than the physical cores.
The processor is clocked at 4000 MHz and has a boost clock of 4200 MHz, which is quite satisfactory for most people, as it is a mid-ground between performance and heat emitted. All these AMD FX-X3XX series processors come in Black Edition, which means that they come with an unlocked multiplier, allowing the user to overclock them. This processor wont work on AM3 motherboards.The same is the case with all AMD FX-series processors.
The performance of the processor is quite good in gaming and at stock clocks, this processor should be able to handle almost all games at above 60 frames per second on the average. The sheer number of cores here does help in the latest games and if you are low on budget and want the best bang for the buck, this processor should be great for you. The TDP of the processor is around 125 watts, which is a bit high compared to processors these days and that is why you must couple this processor with a cooler good enough to keep it under 75 degrees and the likes of Cooler Master Hyper 212 should do the job.
AMD FX-8350 keeps a great balance between performance and price, which is why this processor is one of the best among the FX-series processors for most people who are interested in making a low-budget rig. The processor is still capable of playing most games at smooth FPS and you should not be worried about performance for another two or three years, thanks to the high number of cores.
- A balance between TDP and performance
- Great performance in most games
- Somewhat hot
AMD FX-6300 is the younger brother of AMD FX-8350 and is priced lower as well. The processor is built on the same architecture but the difference lies in the specifications, where the frequency and the number of cores are notable.
AMD FX-6300 is a hexa-core processor, providing six physical cores and six physical threads. The frequency of the processor is lower than FX-8350 but this processor has an unlocked multiplier as well and if you have a good enough motherboard for it, you can probably push it beyond 4.5 GHz easily, leaving behind stock FX-8350.
The cache of the processor is unaffected, at 8 MB, which is a great thing while Intel counterparts reduce the cache as well in lower-end processors. As for the performance of the processor is concerned, six cores should be able to handle most of the games at a smooth frame rate and in fact, many FX-8350 owners will notice that most games are not actively using eight cores of the processor, which makes FX-6300 a bit more competitive. Moreover, the TDP of the processor is lowered as well, at 95 watts but you still would require a good cooler if you want to overclock the processor beyond 4.5 GHz.
AMD FX-6300 is a cheap processor that you can easily get your hands on and coupling it with a good motherboard and cooling solution, you won’t be suffering from FPS drops in games, apart from games like Assassins Creed Odyssey, etc.
- Cheaply available
- Good enough performance for most games
- Not as future proof as FX-8350
AMD FX-9590 is the flagship processor from the Piledriver architecture and no doubt it is a mighty processor, leaving all the other FX-series processors in the dust.
AMD FX-9590 is an octa-core processor just like AMD FX-8350 but it is a binned processor, which means that only those processors that are capable of hitting clock rates beyond 4700 MHz are labeled as FX-9590. On top of that, you don’t have to overclock this processor, as this processor comes overclocked out of the box fairly high, having a base frequency of 4700 MHz and a boost frequency of 5000 MHz.
Although this processor has a very high frequency of 5000 MHz, do not confuse this processor with the likes of processors that we have these days hitting 5000 MHz because the difference in IPC is a lot and this processor cannot perform tasks at even half of the speed of processors like Intel Core i9-9900K.
The high frequency of this processor is a double-edged sword though and the reason for this is that it hugely increases the TDP of the processor, up to as much as 220 watts. This much heat is a lot for a processor and you must couple it with a high-end cooler to properly utilize this processor, however, some of these processors also came with a liquid cooling solution and that should be able to handle it well.
As for the performance of the processor is concerned, this processor can keep above 80 FPS in most AAA games with a few exceptions and if you have a low budget but want the best processor from the Piledriver architecture, this processor is the best choice for you.
AMD FX-9590 is the master of FX-series processors, providing a large number of cores in combination with high frequency, allowing the users to play games much more smoothly than other FX-series processors.
- Requires powerful cooling
- Fastest processor from the FX-series
- Price makes it a bit inefficient
AMD FX-8320 is a processor that is extremely similar to the AMD FX-8350 in terms of technical specifications. The processor comes with eight cores and eight threads, with stock clocks slightly lower than the FX-8350.
The processor is clocked at 3500 MHz with a boost clock at 4000 MHz. Although the clocks of the processor are lower than FX-8350, you can mitigate the difference in performance by overclocking it and this processor should be able to hit past 4500 MHz too if you use a good motherboard and cooling solution with it.
The major difference between FX-8350 and FX-8320, apart from the higher frequency, is that FX-8350 is more likely to overclock higher because of binning. The difference should not be very noticeable to an average user and that is why you can do gaming fine on FX-8320 and get stable 60 FPS in most AAA games.
AMD FX-8320 is like a cheaper variant of FX-8350, having a lower stock frequency, however, once-overclocked, it gets a big performance gain as long as you keep the processor cool by using a high-end cooling solution.
- Cheaper than AMD FX-8320
- Similar gaming performance to FX-8350
- Might not go as much as FX-8350 in overclocking
The next processor that we have on the list is AMD FX-8370, which is also very similar to AMD FX-8350. This processor is a better-binned variant of AMD FX-8350, which makes it slightly pricier and slightly better in performance as well.
AMD FX-8370 comes with eight cores and eight threads and has a base clock of 4000 MHz while its boost clock is rated at 4300 MHz. The difference in clock rates is not noticeable at all but there might occur a bigger difference in overclocking.
The gaming performance of this processor is still not going to deviate a lot from the FX-8350, just like the FX-8320 and you should rather look at the availability of any of these processors instead of targeting one.
AMD FX-8370 is the finest processor from the FX-8XXX series and hence provide top-notch performance, thanks to high core count and frequency. Once overclocked, the performance of the processor gets very close to AMD FX-9590 and you should have a smooth gaming experience with this processor.
- Good overclocking capability
- Much more competitive than FX-9590
- Not a big difference from FX-8350
AMD FX-4300 is one of the lowest-end processors from the Piledriver architecture and this processor has a very low price these days, making it great for those people who just want to enjoy the prime games of their childhood.
AMD FX-4300 is a quad-core processor and comes with four threads as well. The L3 cache of the processor is half of what is found in the FX-83XX processors, which definitely limits the capabilities of the processor. The processor has a base clock of 3800 MHz and has a boost clock of 4000 MHz, which means that even though this processor has a lower number of cores than AMD FX-6300, the stock frequency of the processor is higher than AMD FX-6300.
Since this processor is also a Black Edition processor, this means that you can overclock the processor, and due to the low TDP of the processor, you might not require a cooling solution as powerful as you would require for the likes of AMD FX-8350.
The gaming performance of the processor is not so good in the latest games, as this processor not only lacks high single-core performance but also has a low number of cores. This makes this processor good for games before 2016, where most games utilized four or fewer cores.
AMD FX-4300 is the cheapest processor from the Piledriver-based FX-series processors and despite the cheap price, it comes with an unlocked multiplier and four cores. The processor is capable of handling most games before 2016, however, you might not get a smooth experience in the latest AAA games where Shadow Of The Tomb Raider, Metro Exodus, Battlefield V, etc. are worth mentioning.

- Lower TDP than other FX-series processors
- Might not handle new games well
AMD Phenom II X4 965 is a processor that is based on the K10 architecture, which is the predecessor to the Bulldozer architecture, which was in fact, the predecessor of Piledriver architecture. This processor has the AM3 socket but due to the backward-compatibility of the AM3+ socket, this processor should work fine in the motherboards with AM3+ socket.
The processor comes with four cores and four threads and supports both the DDR2 and DDR3 memory, although AM3+ motherboards support DDR3 only. In this microarchitecture, there was no boost clock of the processors, which is why the processor has only the base clock of 3400 MHz and no boost clock. This processor, however, comes with an unlocked multiplier, although most of the other processors based on the K10 architecture are locked. The processor has a low L2 cache of 2 MB, which is worth noting because this is a processor that predates the L3 cache system.
If the clock rate of the processor would be slightly higher, its performance would be very close to the performance of AMD FX-4300, however, 3400 MHz is not a high clock rate for this era and that is why this processor is not suitable for AAA games after 2015. The TDP of the processor is somewhat high for its frequency, at 125 watts, which is why it requires a good-quality cooling solution.
AMD Phenom II X4 965 is an old processor that comes with four cores and four threads and it is a processor that is cheaply available in the market due to being obsolete for many people. If you are someone, who is going to play rather old games, this processor should still enough to provide you with fair frame rates, however, this processor cannot do high-end gaming, especially for the AAA games released after 2015.
- Very cheap price
- Lower TDP than other FX-series processors
- Might not handle new games well
