"It's fairly unlikely that Tbred will support SSE2. SSE is likely, but not SSE2. And, imho, that's also much more important. The double precision fp performance of the K7 core is more than capable of holding its own - even without dp SIMD." True. Assuming that AMD will be quickly moving Hammer into the mobile market it would be extremely difficult to justify SSE2 in Thoroughbred. The value of dp SIMD is questionable and, according to Intel, scalar SSE2 only buys a 5% performance increase in SPECfp. The performance increase will be greater for the enhanced SSE2 (TFP) of Hammer in x86-64 because of the increased number of registers, but even less in Thoroughbred. But, if Hammer will not be moving quickly into the mobile market, the inclusion of SSE2 could become another check list item that is make or break with some potential sales. Of course, if mobile Thoroughbred's competition in 2002 is limited to Tualatin, SSE would be more than adequate, both to compete against Tualatin and, in the case of IBM having a license to produce an SOI 0.13-micron shrink of mobile Palomino, also adequate to insure IBM can not undermine AMD's own mobile market.
