I'm typing this on a PC which, according to Windows, has an Intel Core2 Quad CPU Q8200 running at 2.33 GHz. I can easily find this out, by right-clicking on the My Computer icon and choosing the Properties option.
But just how good is a Q8200 compared with, say, an AMD Athlon 2800+?
With so many hundreds of processor options available, how do you know whether the new machine you want to buy is actually faster than your current one? And, if so, by how much?
Here's a quick and easy answer. There's a huge list of CPUs at www.cpubenchmark.net/cpu_list.php. From which I can see that my particular Q8200 has a Passmark of 3337 (which seems quite good), and is ranked 97th in the list.
So next a friend or colleague asks you which of 2 machines is the fastest, you'll know where to start.
