Cyrix Media GXm 180GP
First of all: despite being socket 7 (PGA296) this CPU is not compatible with normal socket 7 boards. If you try to use it in such boards you may end up with a fried CPU!
The Cyrix MediaGX is based on the Cyrix Cx5x86 CPU core with hardware to process video and audio output (XpressRAM, XpressGRAPHICS and XpressAUDIO). It was used in some laptops and Compaq Presario systems.
Eventually the technology ended up at AMD's since AMD bought the technology from National Semiconductor in 2003. Both the Geode GX and Geode LX are based on the MediaGX core. The Geode NX is different and based on AMD's own 'Thoroughbred' core that was used for the Athlon XP.
