CPUID Instruction Viewer is a portable app designed to help developers view technical information returned by the CPUID instruction from the x86 and x86-64 instruction sets.
The CPUID instruction returns results about the capabilities and features supported by the processor that this utility is running on. Such results are intended to be viewed along with the accompanying Intel or AMD technical documentation.
CPUID Instruction Viewer can provide the basic information, or you can click on CPUID for more information, including links to AMD or Intel documentation. It's free and easy to use.
