The Processor

There are several things to consider when you are choosing a processor for your computer. The most important of these are speed, form factor, cores, L2 cache, and reputation.

CPU Speed

The frequency (or speed measured in MHZ/GHZ) determines how many calculations your processor can perform per second. Faster chip means more calculations. If you plan on doing routine, low level range you can get a lower frequency processor. If you want to play high end games, work with CAD or video processing you’ll want more speed.

Form Factor

The form factor of a CPU refers to several things, most important of which for the do-it-yourself computer builder is what socket it fits. You must purchase a motherboard that supports your processor’s form factor. Current AMD processors fit into the AM3+ Socket and Intel fits in the LGA 775, LGA 1155, LGA 1156, LGA 1366, LGA 2011. Definately keep an eye on your Intel selections!

Cores

Architecture refers to such things as the number of cores, the bandwidth, and the chip’s internal circuitry. In general, multi-core processors outperform single-core processors, and some CPUs have internal circuitry that makes them perform better than other chips running at the same clock speed. However, some applications may not support multi-core processors and you may not notice an increase in performance (this is rare though). High End computer builders may want 8-Core processors where lower end computer should use 2-Core or 4-Core.

L2 Cache

L2 Cache is used to anticipate what the processor will request from the memory.With L2 cache, more is always better. Look for a chip with at least 1 MB of L2 cache per core. Although this significantly increases the cost of the CPU, it’s worth the investment.

Reputation

Always check the reviews of the processor from the place you intend to buy it from! When choosing between AMD and Intel there is hardly problems with the processors and reputation and reliably are second to none.

The processor I chose was an AMD FX-8120 3.1Ghz 8-Core Processor. It is not the fastest AMD available but it has 8-cores and plenty of L2 Cache for a mid-range gaming system. It is currently the latest AMD processor available. The previous models were the Phenom series. As you can see from the description below the processor fits into a socket AM3+ motherboard. If you remember from the previous page, the motherboard I chose was AM3+ compatible.
