<Jim: The P4 seems an odd chip> Warning. WAGs ahead! Certainly wasn't designed as an all 'round chip... Intel apparently decided that they needed to get away from x87 to maximize performance. Due to what you could well call arrogance, they sacrificed x87 performance. Intel decided that they needed to maximize bandwidth to maximize performance. Due to what you could well call arrogance, they decided to not to hedge their bet on memory type. The way I read this whole situation (and others would likely know significantly better), Intel simply didn't expect anyone (AMD) to be competitive when P4 launch time came around. This meant that they believe they could concentrate on improving performance for "future" applications, while sparing relatively few resources on "legacy" programs. Where the double-clocked ALU+some_more figures in all this, I have no clue. -fyo

<< It also seems to rely heavily on SSE2 optimization, not unlike the K6-2 relied on 3DNOW to achieve good gaming scores where as the P-II was the more well rounded chip with the stronger FPU... >> SSE2 probably has a minimal effect on gaming performance. Quake 3 arena is not SSE2 optimized. There probably aren't significant SSE2 optimizations that can take place since there probably isn't any double precision floating point code in the game. (or a very minimal amount). The high quake scores likely represent the higher memory bandwidth provided by rambus/quad pumped fsb. SSE2 optimizations played out heavily in SPEC I'm sure since many of the specfp benchmarks use double precision floating point.
