Cpu info using cpuid and WMI on windows are different Tags: CPUs Processors Last response: June 21, 2011 9:36 PM in CPUs Share anarki June 21, 2011 6:34:48 AM I did two tests to fetch cpu info on windows system. First one is using __cpuid as mentioned here: LINK and another one is based on WMI. My processor is (AMD Athlon(tm) 64 Processor 3200+). Using __cpuid : Model = 15 Family = 15 Stepping = 0 Using WMI : Family 15 Model 31 Stepping 0 Model is different. When running this code on another machine with AMD64 Phenom II X2 555 processor: using WMI : Family 16, Model 4, Stepping 3 using __cpuid : Family 15, Model 4, Stepping 3 Family is different. The values are not equal. Any pointers? To get processor info using WMI, you can type wmic cpu get caption on command line.
