It provides a single overall score derived from multiple smaller tests, including JPEG and PNG decoding, SHA512 and Twofish encryption and BZIP compression. Find out more about how we evaluate games and hardware.Ī program called Geekbench is now perhaps the most widely used CPU benchmarking tool, partly thanks to being comparable across Windows, OS X, iOS and Android. PC Gamer's got your back Our experienced team dedicates many hours to every review, to really get to the heart of what matters most to you. Comparing your own results with reviews of the latest hardware can assure you that your PC is in tip-top shape, help you gauge the success of your latest overclock, or tell you that it's time for an upgrade. You can run this software yourself to roughly work out how fast your computer is performing. Whenever a new processor platform is launched, this is the big area of scrutiny, since default clock speeds don’t seem to be progressing greatly with each generation, and quad-core chips are generally standard for new consumer CPUs.ĭifferent testing software focuses on one or all of these aspects of a CPU.
This changes from generation to generation of CPU, and differs vastly between AMD and Intel processors. The last, more complex factor, is the overall efficiency of the architecture, including the number of instructions executed and the number of registry calls per cycle. But today’s multi-core CPUs can run a number of entirely separate programs (or processes) at the same time, while some programs can be written to use all available cores at once to speed up whatever they’re doing (a multi-threaded application). Higher clock speeds still matter, as that’s the number of cycles that are being executed each second. On the hunt for a new processor? Check out our guide to the best gaming CPUs.īenchmarks can help you understand what all those CPU specs really mean.
