From eyeballing the result, it seems the numbers you quote agree with me that the 2.0Ghz Opteron is faster than anything else. Note that the Opteron number you quote is Intel C in 32 bit mode on Windows. This seems to be faster than a native GCC 3 (they don't give the exact version unfortunately) compile. Amazing - this means there is still a lot of room for further improvement as the compiler gets better. I used the native GCC compile numbers. The Pentium 4 was in a similar situation with Intel C 6 and 7 giving a big performance boost to some programs (You can also see this in the SPEC results). Unfortunately I haven't seen a single version so far that doesn't crash when compiling Deep Sjeng, so those numbers mean very little to me. GCC 3.2.2 on the other hand gives the exact same results in 32 bit Athlon vs the 64 bit Opteron versions - no bugs there! -- GCP
