The CPU or Central Processing Unit (or processor) is essentially the brain of the computer—all operations that are executed by the computer are run through the processor, making it a crucial component for determining the speed and power of a system. Since the dawn of the personal computer era vast improvements have been made to chip architecture and processing power, which means consumers now have yet another data point to consider when purchasing hardware—usually one associated with an arcane and mystifying chain of letters and numbers. So, what does it all mean? What should a consumer consider when shopping for new system?


  • How many cores? Processors that have multiple cores are now the norm. For most users, anything less that dual core will be too slow in running programs and for power users, such as gamers, designers and media editors, you’ll want to consider a quad core, six core or higher.


  • Speed Until it Hertz Processor speed, also called “Clock Speed,” is a measurement of how many electrical pulses go through the processor per second. This is measured in “gigahertz” or the number of billions of times that the processor clock pulses in a second. So in many cases, a CPU with specs at 3.3GHZ will be preferable to one clocked at 3GHZ, with one caveat: Cores matter more—a quad core processor 3GHZ CPU will perform better than a dual core clocked at 3.3GHZ.


  • Who makes the best one? And how much does the best cost? There are currently only two big names in the CPU game, Intel and AMD. The earliest microprocessors were made by Intel in the 1970s and their research and development has largely driven the massive advances we have seen in the intervening years. But while Intel is on the cutting edge, AMD has been able to produce processors that are more affordable. There is a tradeoff of course, AMD’s processors tend to have more heat management issues and less longevity.


As is often the case in the tech world, consumers pay a healthy markup for the next best thing. With the advent of Intel’s i9 processor this year, the cost on the i7 and i5 will surely fall, sending some still quite impressive computing power into a more affordable market.
