What to Look for Before Buying
Buying the right processor depends on several factors. We’ll talk about the things that you must look for in an AM3+ CPU to make the buying process easier.
A processor is comprised of multiple cores, which are essentially processors inside the processor. Each of these cores is capable of taking on multiple tasks at once. They work together to provide more power for faster processing.
Four cores should be just about enough, but if your requirement demands more power, you can opt-out for units with more cores.
Threads refer to the number of processes that a chip can deal with at once. In general, it should be the same as the number of cores in your CPU. However, some powerful CPUs offer multithreading. This means a single core can produce two threads. You will have better multitasking performance from more threads.
The CPU cache is the memory that is utilized to speed up the access of data from a computer’s hard disk or RAM. It decreases the average time that takes to access memory. You will find caches in three different formats. The L1 offers the fastest operation, but it doesn’t have much room for data storage.
You will find the L2 to have more room, but it operates much slower. The L3 offers the most space by sacrificing speed, so it’s quite sluggish.
Clock speed is simply a measure of how fast a chip can operate. Naturally, the higher is faster and, of course, better. It’s evaluated in gigahertz or GHz. CPUs come with different clock speed settings. They automatically set the clock speed depending on the tasks and the unit’s temperature.
Some CPUs offer an overclocking feature, which allows you to push the speed of the chip to operate even faster than specified.
CPUs produce a lot of heat in operation. This heating can lead to the damage of the CPU unless it’s controlled. That’s why your CPU should have a decent cooling system to reduce the temperature to prevent heat inflicted damage.
AM3+ CPUs come with a very effective cooling system. However, it won’t hurt to be extra cautious.
Make sure that your motherboard is designed to support your choice of AM3+ CPU. Every motherboard comes with a CPU socket, but they aren’t made to be compatible with all the CPU models. Therefore, you must make sure that your motherboard has the socket that matches your choice of CPU.
Another thing you must ensure is that your motherboard must have the correct chipset that can accommodate to your CPU. Otherwise, your motherboard won’t be able to handle your CPU at all.
You must make sure that your power connection is safe and secure. The cable that bridges the connection between your power supply and the motherboard must be long enough. Many CPUs require an immense amount of energy, so you should get a power supply that is strong enough to provide adequate power.
The fact that AM3+ CPUs still hold their ground amidst the more powerful Ryzen and Intel processors say a lot about its capabilities. They are widely available at lower prices, but our reviews should tell you how viable and effective they still are. Some of them can prove to be even better than more expensive ones.
We consider the FX-8350 to be the best AM3+ CPU. It offers impressive performance through its powerful 8-cores and decent cache. Best of all, it’s conveniently cheap, so it won’t break your bank.
You can go for it confidently as it has everything that you look for in an AM3+ CPU. The FX-6300 and the FX-8320 are almost equally amazing, guaranteed to satisfy you through their incredible performance and affordable price design.
