Tenchusatsu, it may be that AMD added registers to 3DNow, since I've heard that there is no overhead switching between FP and 3DNow anymore. Of course, that moves the overhead to OS context switches, just like Intel's SSE. We'll find out by 6/30. Petz

Ten - Re: "But does the K7 add more architected registers? Pentium III's SSE adds eight new 128-bit registers to the x86 architecture, a move that was described as "about time" by Microprocessor Report." I don't know. What Dirk is saying is that the original 3DNOW implementation was poor and inferior to the Intel SSE implementation. Thus, that 9 month "lead" in which nothing but a few games supported 3DNOW has evaporated and Intel is winning ! AMD developers will now have to choose to develop 3DNOW or "new & improved 3DNOW" software - or BOTH - which will really dissipate their efforts. Paul
