MacCPUID is a developer tool used for displaying information collected from the microprocessor via the CPUID instruction. The CPUID instruction returns information in the general purpose registers such as manufacturer identification, a processor's family, model, and stepping numbers, supported features (e.g. SSE, SSE2), cache information, and many others.

http://www.intel.com/cd/ids/developer/asmo-na/eng/321760.htm This is a really old one 1.0.0. From 2006. Does Intel not update it for newer CPUs ? Also would be fine if showing the VID (mVolts) also :) Thanks
