CPU-Z is a freeware detection program base on the Panopsys hardware detection engine.
It allows to get some information on your system, including :
CPU-Z also provides several tools :
This tool computes the real latency of each cache memory level. Notice that the reported sizes may not be the correct ones on CPUs that use an exclusive L2 (for example a Duron will report a 128Kb L2 cache size instead of 64Kb, because the L1 size in included).
Moreover, notice that using this tool if the CPUs is heavy loaded can provide bad results. Please use the “Refresh” button to restart the calculation.
