Back in the day, we measured CPU performance, and kept track of things like megahertz and gigahertz to indicate how much power we could afford.
For some reason, all those wonderful bullet points just don’t mean what they used to mean. Who knows how fast a Mac or PC is today? Apple still sells Macs with different speed CPUs, but that measurement just isn’t what it used to be. So, how fast is your Mac? How would you know.
For that, you’ll need Geekbench to measure your Mac’s CPU (central processor unit; the big chip that means Intel is inside) and memory (RAM).
Install Geekbench, then run a series of benchmarks and a few minutes later you’ve got a list of CPU and RAM performance on your Mac and how it stacks up to other Macs.
In the end you get scores for each of four basic benchmarks, and a total score for your Mac.
The benchmarks include processor integer performance, processor floating point performance, memory performance, and memory bandwidth performance.
Your Mac’s score can be compared with other Macs. Geekbench supports 64-bit and 32-bit mode. Oh, and it’s cross platform, which means there’s a Windows PC version, hence a way to compare your Mac to a PC.
All this is well and good but Geekbench is missing a few measurements. First, there’s no graphic CPU performance measurement. Second, there’s no hard disk drive or SSD storage tests. Both graphics and storage access are important components in standard benchmarking, and sorely lacking in Geekbench.
