Buying Guide

Whether you believe it or not, purchasing the best AM3+ CPU usually depends on a few factors. If you do not follow or abide by them, then you may end up buying the wrong one instead. So, to help you with it, here, we are going to provide you with a comprehensive buying guide. Make sure to check it out in a proper manner!


As you probably do already know, the processors generally consist of multiple different cores. Each of them is somewhat different than one another and, thus, can take care of diverse duties.

So, in essence, if your processor has a decent amount of cores, then it will work a lot faster than other modules. Anyways, if you are thinking about only doing your daily tasks on your computer, then going for a three or four-core product should be ideal for you.

However, for gaming, you would require more power and, therefore, have to choose a higher core product.


To make things tick, you will have to connect your processor to the motherboard through a socket.

Hence, if you are buying the best AM3+ CPU, then make sure to purchase a compatible motherboard as well or vice versa.

If the socket does not fit with the motherboard, then the CPU would not get the power of running properly.


In the case of a CPU, the term’ thread’ refers to the number of procedures it can take care of at a time. In most cases, the threading option would be the same as the number of cores your CPU comprises of.

Nevertheless, some of the high-priced and powerful processors tend to be multithreading. In this aspect, one of its cores can generate around two threads or more simultaneously. Thus, with them, you will be able to relish a superior multitasking-based performance.

Overall Clock-speed

The clock speed of a CPU generally measures how fast it can work. In general, if your chipset has a higher clocking-speed, then it can operate a lot quicker than usual and, thus, provide superior performance while you are playing high-end games.

Thus, if you wish to buy the best AM3+ CPU, then make sure to check if it has a maximum clock speed of over 4.0GHz or not. Otherwise, it would not be up-to-the-mark for 1080p or 4K gaming purposes.  

Cooling System

In essence, the CPU of your computer has to take care of a lot of different operations. Thus, sometimes, if you are using your PC for a prolonged period, then it can get overheated.

In this case, if it does not have a decent cooling system, then it might get damaged due to the temperature issues. Due to this reason, while checking other factors, you should take a look at its cooling system as well.

In essence, the cooling system of the AM3+ CPUs tends to be pretty decent. Nevertheless, still, being extra cautious in this aspect would be excellent for you.

Motherboard Compatibility

No matter which processor you are buying, it needs to be suitable for your system’s motherboard. If it is not, then a lot of issues can happen in this case. For starters, your CPU would not get enough power to run correctly.

It, in turn, might cause lags in the game. Moreover, sometimes, the socket systems might not match with the motherboard as well. Thus, it would be literary impossible for you to install your processor in your system.

Power Supply

The best AM3+ CPU would, undoubtedly, require a decent amount of power to run efficiently. Thus, along with a compatible motherboard, you will have to use a high-end power supply system as well.

It should be around at least 800W. Moreover, you will also have to make sure that your power supply is in a safe condition. The cable, which connects the motherboard with the power supply, should be long enough as well.


With the cache of a CPU, you can measure its overall data transferring capability, which occurs between it and the RAM. Usually, the cache is measured in megabyte and, its storage options can be categorized in three different formats. Let’s know a little bit about them.

  • L3: The L3-based CPUs do have a lot of cache space. However, they tend to be a lot slower than usual.
  • L2: The L2 setups generally come with a lower amount of space than L3. But, they are a lot faster and tend to transfer data pretty quickly.
  • L1: The operational speed of the L1 modules are known to be the fastest. Nonetheless, they do not have a high capacity at all.


In essence, the AM3+ chips of AMD were primarily made for gaming purposes. However, since then, the brand has evolved a lot and, currently, caters to the different multimedia applications as well.

So which one among the options seems to be ideal for you? Well, if you ask us, we would suggest you go for the FX-8370 model. However, if it does not seem to be too powerful for you, then you can also choose FX-9590 for your purpose.
