The Cyrix MII was a microprocessor from the Cyrix company and is nothing more than a renamed Cyrix 6x86MX .
Cyrix presented this CPU on April 15, 1998 after the takeover by National Semiconductor and thus disappointed the professional world: Instead of a revised processor design, only a renamed Cyrix 6x86MX was presented. The models MII-300 and MII-333 with their relatively low clock rates could not hold their own against the competition in the form of the AMD K6-2 and the Intel Pentium II and the sales figures plummeted accordingly. IBM did not follow this name change and continued to sell the MII-300 and -333 as the 6x86MX-PR300 and 6x86MX-PR333.
After VIA Technologies ( Taiwan ) took over Cyrix in mid-1999 , the first step was to hand over the production of MII CPUs to TSMC . Thanks to The - Shrinks to 0.18 microns could the clock speeds are slightly raised, so that you can still MII 366, MII-400 and MII-433 brought to market. All in all, however, the MII sealed the downfall of the Cyrix company.
