Do you think it is fair to compare PIII with optimized SSE vs. Athlon and no 3DNow? I don't agree. Most (if not all) of the Athlon optimized code out there (e.g. Direct3D, 3DMark2000, 3DWinBench2000...) is also optimized for 3DNOW (even the enhanced Athlon version of 3DNOW) Haim

Scumbria, Re: "Athlon floating point performance is considerably faster than PIII, but Intel has better compilers which use SSE. Do you think it is fair to compare PIII with optimized SSE vs. Athlon and no 3DNow?" After reading those comments on Aces Hardware about Willamette, I don't know whether it is fair NOT to compare using SSE. It seems that Intel takes the approach of SSE to tackle the poor floating point performance issue. So to some extend, even though PIII or Willamette can still be called x86, they are morphing into something beyond that in particular for the FPU. The x87 compatability is there just like Itanium can execute x86 code, just for easier migration, but Intel's hope is that FPU intensive application in the future will base on SSE. Comments ? Gary

Scumbria, re:"Do you think it is fair to compare PIII with optimized SSE vs. Athlon and no 3DNow? Do you think it is fair to compare a GHz Athlon vs. a non-existent GHz PIII?" Excellent points. You even got the iNtEL reserves from overseas to try to twist your points. iNtEL is desperate. steve

Re: "Athlon floating point performance is considerably faster than PIII, but Intel has better compilers which use SSE" I believe this is incorrect on 2 counts. First Athlon FP is only slightly faster and second, Intel's compilers only use the prefetch instructions which Athlon uses also. Intel's compilers are publicly available and AMD can do an apples to apples benchmark comparison however they continue to claim the compilers aren't available and they continue to refuse to explain how they got the poor CuMine FPU scores which no one else in the world has been able to duplicate. This is dishonest period. Re: "Do you think it is fair to compare a GHz Athlon vs. a non-existent GHz PIII?" This is incorrect. The GHz PIII is available however in very limited quantities. EP
