What To Look For When Buying Best AM3+ CPU

Following are some of the best features that must be taken into consideration while buying the Best AM3+ CPUs for 2021:


Nowadays, even if you run those games on single-core processors, they won’t give you a significant performance increase as there is no way that a single core can outdo the numbers which we get from our modern-day CPUs with 4 and more cores.

Cores and threads both contribute to enhancing your CPU’s performance and hence it is wise to look for a CPU with a good number of cores.

The FX-9590, for example, comes with 8 cores which can give you up to 16 threads by enabling Simultaneous Multithreading (SMT).

High Clock Speed

Not all processors are available in multiple variants i.e., low power and high power. There are some which are only available in the high clock speed variants.

For example, FX-9370 has a base clock of 4.7 GHz and an unlocked multiplier which can be overclocked further to 5 GHz if you have an aftermarket CPU cooler or liquid cooling solution.

Multi GPU support

If you run a dual graphics card configuration or plan on doing so in the future, you should look for a CPU that provides good support for multiple GPUs.

For example, if you go with an AMD FX 8350, it will support Crossfire configurations of up to 4 GPUs but if you choose FX-9590 which has 20 PCIe lanes, your motherboard will support CrossfireX configs of up to 4 GPUs.


You should look for CPUs that offer the best performance at a reasonable price. For example, if you are thinking of moving from an old AM3 processor to a new one, it might make sense to spend a few extra bucks on getting a CPU with better clock speeds.

You should also look for CPUs that are cost-effective and don’t burn a hole in your pocket.

Hyper-threading support

Hyper-threading allows the operating system to recognize one physical CPU as two logical CPUs which can result in better multitasking performance.

For example, if you run a game on one core and a video editing application on another, you can allocate both these tasks to different physical cores.

However, it has been seen that the performance boost which you get from Hyper-threading isn’t exactly very high and not everyone needs this feature in their CPU.


The cache is a small memory bank inside your CPU which is used to save frequently used data and instructions so that the CPU doesn’t have to read from the main memory every time it needs that information.

The more cache a processor has, the more efficiently it will function. For example, if you run a program that uses a lot of instructions and processes on your CPU, it will make use of the cache to retrieve that data.

If the program doesn’t use very complex instructions, the processor will be able to make use of that instruction more frequently which results in better performance.


AMD FX processors are only compatible with AM3+ motherboards while Intel CPUs can be used in both LGA 2011 and 1366 sockets. If you go for a newer socket, make sure your motherboard supports it before buying a CPU.

Single vs Multi-threaded Performance

For gaming purposes, the number of cores is more important than the overall clock speed. However, some tasks will be better performed on CPUs with higher clock speeds i.e., a quad-core running at 2.8 GHz is more likely to outperform an octa-core running at 1.6GHz when it comes to video editing and rendering applications.

If you look at the single-threaded performance of processors, it has been seen that they can perform similar tasks even with an octa-core running at 1.6GHz.

For example, the biggest difference in single-threaded performance between FX 6300 and FX 4300 was 12% while the difference in multi-threaded performance between these two CPUs was 46%.

Cache size

The cache memory in your CPU should be checked depending on the type of tasks you will be performing on your processor.

If video editing or rendering applications are what you will be using most often, look for a CPU with plenty of caches to support that application. FX 6300 has 6MB of L2 cache which is more than enough for video editing or rendering applications.


As mentioned above, hyper-threading allows the operating system to recognize one physical CPU as two logical CPUs which can result in better multitasking performance.

For gaming purposes, it has little to no effect on the overall performance of your PC so you can either go with a processor without hyper-threading or one which has it.


AM3+ is a CPU socket that can support both AMD and older Intel CPUs. However, newer sockets like LGA 2011 only support the latest Intel chips while LGA 1366 supports mostly older processors from Intel. You should choose a CPU depending on what type of motherboard you have now.


  1. What type of CPUs is suitable for AM3+?

    AMD currently makes three different CPUs for the AM3+ socket, the FX-4300, the FX-6300, and the FX-8320. The entire range of Bulldozer processors is compatible with any AM3+ board that has a 942-pin CPU socket on it.

  2. What is the highest-performance AM3+ CPU?

    The fastest AM3+ processor is whichever one you can get your hands on quickest. Whether it be the FX-9590 (5 GHz) or FX-9370 (4.7 GHz), AMD's latest enthusiast chip will push your rig to new highs in clock speed.
    However, no matter which one you choose, the fact remains that both chips are extremely expensive and overclock relatively.

  3. Is Ryzen compatible with AM3+?

    If you already own an AM3+ motherboard, the good news is that most likely it will be compatible with Ryzen CPUs because both use DDR4 memory and have power requirements in common (up to 95W).
    The only concern is whether your motherboard has the very specific 8-series chipset which is required to use the newest X370 or B350 chipsets.


There are several superb alternatives when it comes to processors for your PC, and all the formerly cited processors are the Best AM3+ CPUs for 2021 but if you had to select one, I would very much vote for AMD FX-9370 Black Edition.

Underneath the hood, this processor has all your bases covered. It’s got whopping machinery that will allow you to multitask like never with its brilliant AMD Turbo Core Eyefinity Technology.

It boosts your computer’s performance to the max with its exceptional features. This product maximizes computing power and efficient power consumption, giving you all the bragging rights in any video game or rendering application.

The robust liquid cooling system ensures this powerful chip runs cool so it will be ready when called upon at any moment’s notice whether it’s work-related tasks like video editing or personal ones such as streaming videos on Twitch while playing games online simultaneously all night long.

As a successive choice, I would recommend readers consider the AMD FX-8350 Black Edition.

It’ll run all types of tasks quickly and efficiently, with its maximum performance specifically tailored to give you what you need to accomplish more on your machine while simultaneously reducing the waiting time between commands, so projects go smoothly without frozen screens interrupting productivity.

It features Hypertransport Technology to ensure fast processing speeds with minimal lag time or risk of glitches common in other systems making it perfect if you want your game loading up faster than ever before.

I’m so eager to read your thoughts on this article because I want your immediate response. Please jump into the conversation in a few seconds and tell me what you think of Best AM3+ CPUs for 2021.
