CPUFeatures plug-in

Author: LoRd MuldeR (talk, contrib)

This very simple plug-in can detect the supported CPU features (MMX, 3DNow!, SSEx, AVXx, FMAx, etc) at runtime.

Furthermore the number of available CPU's (aka "CPU cores") as well as the CPU vendor (Intel, AMD, other) can be reported.

ANSI and Unicode builds available. Support operating systems: Windows 2000 and later.

Acknowledgement: This plug-in is based on CPU detection code from the x264 project. Please see cpu.c for details!

Example
