AM3+ CPU – Buying Guide

Now that you’ve gone through the list of best AM3+ CPU models on the market, let’s recollect the important factors you should consider while looking for a suitable AM3+ CPU.

CPU Socket

A socket connects the CPU to the motherboard. Therefore, it’s critical to ensure the CPU you’re planning to buy has a socket that is compatible with your motherboard.

Cores

The number of cores in a CPU is another important factor you should consider while looking for the best AM3+ CPU. The cores refer to the number of processors in a CPU. Each core can run several tasks at once. Therefore, the more cores, the better would be the multitasking ability of the CPU. Most AM3+ CPUs come with 4 or 8 cores.

Threads

The CPU threads refer to the number of processes your chip can support at once. The number of processes should be equal to the number of cores.

Cache

The measure of the amount of data transfer that can take place between the CPU and the RAM is known as a cache. Higher cache means higher data storage. Cache stores are typically found in L1 (fastest with minimal space), L2 (more space but slow operation) and L3 formats (more space and even slower than L1 and L2).

Clock Speeds

The clock speed is the measure the speed of chip operation. A higher clock speed implies faster functioning of the CPU. Each CPU may come with different clock speeds. When a CPU is pushed beyond speeds that are specified, the process is known as overclocking.

Power Consumption

You may need to connect your CPU to a power source using the power cable that’s shipped along with the CPU. More cores don’t lead to better performance, energy-efficient CPUs do. 

Cooler

Since CPUs produce heat during operation, it’s important to ensure you have proper cooling measures in place for heat dissipation. Even though AM3+ CPUs come with optimum cooling, you need to be on your toes and check your PC’s ventilation.

Frequently Asked Questions About AM3+ CPU

Will Ryzen work on AM3+?

No, Ryzen does not work on AM3+. It can fit into the new AM4 socket and is not compatible with older motherboards

Can I put an AM3+ CPU in an AM3 motherboard

No. Since the motherboard is designed for an AM3 processor only, it does not come with the socket for the extra pin required by an AM3+ processor. Nevertheless, most AM3 motherboards on the market these days come with sockets for AM3+ CPUs.

Do I need additional coolers with AM3+ CPUs?

If you’re not a fan of overclocking, a single cooler would be good enough to dissipate heat while your CPU is running. However, CPUs with more processors require robust cooling solutions.

Are AM3+ CPUs suitable for gaming?

If you’re planning to upgrade an old PC, AM3+ CPUs can be a good option for gaming. However, if you’re planning to build a new gaming PC from scratch, Intel processors would be a good choice. Moreover, if you are looking for multi-threaded performance, Ryzen processors would be the best bet.

Does overclocking increasing the gaming performance of an AM3+ CPU?

Yes, overclocking results in enhanced clock speeds that in turn enhance the gaming performance; however, many gamers do not prefer this method as the scope of enhancement is not significant. Therefore, overclocking isn’t required for a power-loaded gaming performance.

Final Words

First things first, investing in a top-rated AM3+ CPU is a good idea, especially if you run heavy-duty applications on your system. The prices are affordable and the PCs do not require complete upgrades. However, you may come across issues related to heating, gaming performance, power consumption and so on.

While choosing the best AM3+ CPU, ensure you consider all the factors mentioned in the buying guide section to make an informed decision. The best overall AM3+ CPU per users is AMD FX-8320E as it is the perfect combination of optimum power consumption and great multi-threaded performance.
