Below you can see the entire list of programs used to test our processors. Most of the tests make good use of multithreading, but just like real-life situations, there are some tests that prefer higher clock frequencies over number of cores or size of L2/L3 cache buffer. Since Windows 7 64-bit is used from now on as base for processor benchmarks, some of benchmarks are used in 64-bit versions as well.
