Written fully in Assembly Langauge, CPUSpy tests your processor and using an internal database of most common CPUs, displays CPUID data such as cache details, processor features and processor name (if supported) in a easy to read tabbed format. CPUSpy can also measure your current CPU speed in MHz, Windows Up-Time, IP address, Window Version and memory status. In addition, CPUSpy has a cache speed test and all data can be saved in a report file.
