> Bah! we need ISSE2 extra feature as much as we need AGP 8x... no at all! (at least for 2001). Actually, SSE2 is without doubt a better floating-point instruction set than x87 is. Even without the advantage of SIMD, it lessens pressure on the decoder end (because you don't need to use FXCH to jumble around the stack). However, Intel's implementation of SSE2 is disappointing. See, it's essentially scalar in nature, as is Willamette's x87 and MMX implementations. If AMD implemented superscalar SSEx (and I'm not talking about like the double instruction pumping that P6 has to do for SSE) just like they have superscalar x87 and MMX, then SSE2 will become a much more attractive option to several coders that I know. Of course, caches and memory will have to get a lot better to meet requirements of eight sustained 32-bit operands per cycle (or four sustained 64-bit operands per cycle) throughput. Heck, caches and memory still need to catch up with the original Athlon's superscalar x87, which is obviously underperforming its own specs! > If your sources are right, Intel is fckd. This is Intel we're talking about. The company with three times as many x86 fabs as every competitor combined. If the lowest performing Duron beats the highest performing P4XP next year (incredibly unlikely, of course), then Intel will still dominate at least three quarters of the market.     -JC
