A $175 Core 2 Duo VS a $1k AMD CPU
My favorite compression utility (7-Zip) recently released a multitheaded benchmark in the current beta version, so I took everybody's results and put them into a table for your viewing pleasure. Keep in mind this isn't an absolute comparison of CPUs, but it's some serious number crunching in a multithreaded enviroment and the results are usefull.
I took all the CPUs listed above and sorted them in a list from fastest (using all hardware threads) to slowest. Too bad we didn't have any Intel Core 2 Extremes for comparison...
PS: higher is better Threads 1 2
