The CPU, or central processing unit, is like the brains of the computer, translating and performing all the commands of your machine’s hardware and software. When choosing a CPU for gaming, consider these factors:
Manufacturer: The two main CPU manufacturers are Intel and AMD. The performance of each depends on each individual model, but the biggest difference is that all AMD CPUs can be overclocked, whereas only Intel CPUs with the letter K in their model can be overclocked. Overclocking lets you push a processor to work faster than the manufacturer’s specified clock speed, so you can game as hard as you want without burning out. Keep in mind that overclocking often consumes more power and can be potentially risky if not done carefully.
Number of cores: A CPU will have one or more cores for performing tasks. A CPU with multiple cores will be able to run several different programs and the most task-heavy games on different cores, making your computer more quick and efficient. For graphics-hungry games like Max Payne 3 or Skyrim, a processor with four or more cores is ideal. For extreme gaming with 3D graphics like Call of Duty: Black Ops II, a processor with six or more cores will give you all the performance you need.
Clock speed: Clock speed, measured in GHz, is the speed at which a CPU executes its internal operations. While clock speed influences how fast your computer runs, it should be looked at alongside the number of cores. For the optimum performance for playing high-end games with detailed graphics, consider at least four cores at a speed of 3.4GHz. If you want to run your processor above its specified clock speed, look for one that can be overclocked.
