| Originally codenamed M2, this chip was very eagerly awaited. Cyrix had been making grand claims about their superior architecture and this was echoed by Cyrix's small but loyal following. Indeed it did come out, and indeed it is very interesting architecture, but to say the least, it was very late. Both AMD and Intel had announced their 6th generation MMX processors and enjoyed a couple months of extra revenue before Cyrix appeared on the scene. But as always, these Cyrix CPUs have hit the street at a substantially lower cost than its rivals, although recent price cuts from AMD may be marginalizing them at the high end. Well, Intel came up with MMX and AMD was already using it starting with the K6. So, Cyrix had to get in on the game as well. The 6x86MX, also dubbed "M2", was Cyrix's answer. This processor took on the MMX instruction set, as well as took an increased 64KB cache and an increase in speed. The first M2's were 150 MHz chips, or a P-rating of PR166 (Yes, M2's also used the P-rating system). The fastest ones operated at 333 MHz, or PR-466. M2 was the last processor released by Cyrix as a stand-alone company. In 1999, Via Technologies acquired the Cyrix line from it's parent company, National Semiconductor. At the same time, Via also acquired the Centaur processor division from IDT. |
