Nice detective work but I believe the article is wrong. We have seen far too many occasions where the P4 does a poor job of running x87 code. There are no examples of P4 running fast x87 code and we have several examples of programs seeing dramatic speedup when recompiled for SSE2. If we believe the SSE2 only allows for ~5% speedup we must conclude the P4's architectural features will produce a dramatic speedup on older FP code as well and we never see that. Bottom line is I don't believe that Intel article is correct but I don't have time right now to research it. EP
