Cyrix MII 233GP
This is the slowest Cyrix MII CPU within the MII-branding. It runs at a fairly low clock frequency but uses a 75MHz bus to speed things up a bit.
The MII ranged from 233GP to 400GP (rated). The 6x86MX actually uses the same chip as the MII but has a different name; they are available in lower speeds.
Cyrix had problems increasing the clock frequencies of the M2-chip. The 333GP runs at either 250 or 266MHz depending on the FSB-speed. The fastest production models are the 400GP and 433GP at 295MHz and 300MHz. Higher frequencies weren't possible within regular voltage and cooling parameters.
