Elmer,
Pentium I, Pentium II and Pentium III didn't need optimized code to look good. The P4 does. Why?
K6-2 needed 3DNOW optimized code to look good. You dissed that yet you defend the P4. Why is that? How much Intel do you own?

Jim

Elmer, Re: P4 optimized software / SPEC

Thanks for your answer. So you think that SPEC gives the best indication of possible P4 performance in the future? Judging from the results AMD and Intel posted there so far(*), it seems that AMD is roughly on IPC parity in SPECint2000 and at a 25% disadvantage in SPECfp2000. However, with VIA KT266A and Athlon XP coming up my guess is that this will change to a IPC advantage for AMD in SPECint and a parity (or slight disadvantage) in SPECfp. Intel will be still faster overall in SPEC (integer and floating point) but it's not that AMD is hopeless behind in 'new code'. The main disadvantage for AMD is clock-speed right now IMO.

Elmer,

The spectacular P4 performance is gained by compiling with a modern compiler that is P4 aware.

How do you see this will play out in the future with trend being to dump the compilers all together and move in direction of Java and MSFT .NET (CLR platform)?
