Ted, CXT is the name of the enhanced core change the K6-2 underwent at 350Mhz...(circa December '98) which was supposed to propel the core to greater MHz. Unfortunately, in the beginning, while yields were good, bin splits were not. Many chips that were supposed to be 400 and above had to be sold as sub 350 MHz parts. This coupled with the faster Celerons Intel produced to counter the K6-2, put the death nail in AMDs Q1-99 earnings because of the low ASPs and later hurt AMDs credibility with OEMs who didn't flock back to AMD when bins were improved. Officially, AMD blamed the debacle on a late mask problem. Others here, including myself called it a design problem.

Ted, Re:"CXT " The specifics are long forgotten. But AMD implemented a design/process tweak in Oct/Nov of 98 that should have boosted performance and yield of 400Mhz speeds. Unfortunately the new mask with the CXT core bombed. And devices not only failed to yield at 400Mhz but due to some anomoly most parts had to be binned at 300-333 speed grades. This crap lasted thru mid Q1. AMD lost OEMS as they had to scramble to offer alternative CPUs etc. And Intel took advantage of their speed leads to trash the low speed grade prices with multiple price cuts in dec/jan/march. By the time AMD fixed the speed/yield problems they manufactured 6M units in Q2 and could only sell 4M of them. And I am sure the rest you remember. regards, Kash
