CPUSpy interrogates your processor and displays data (if supported) in a easy to read tabbed format. L1, L2 and L3 cache data is fully broken down as are the processor flags. In addition, CPUSpy can also check your current CPU speed in MHz, Windows Up-Time, IP address, Window Version and memory status. CPUSpy even can run a test on your cache memory to provide an easy comparison between various processors or system configurations.
