Phoenix
Athlon64: at 2GHz clockspeed, running SuSe Linux 9.0, compiled with ifc 7
G4_667_PB: Apple PowerBook G4 at 667MHz, 1GB RAM, running OSX 10.3 Server, compiled with IBM xlf95 compiler
dG5: Apple dual G5 2GHz, 2.5GB RAM, running OSX 10.3 Server, compiled with IBM xlf95 compiler
Itanium2_1.3GHz: Altix 32 CPU Itanium2 at 1.3GHz, running Linux, compiled with Intel Fortran compiler v8
P4_2.53GHz: Intel P4 at 2.53GHz, running FreeBSD, compiled with Intel Fortran v7 (FreeBSD native executable)
P4_2.6GHz: Intel P4 at 2.6GHz, running Linux 2.6.1, compiled with Intel Fortran v8
PWR3: IBM SP nighthawk-II Power3 System, AIX 5.1, compiled with xlf95
PWR4: IBM Regatta Power4 System, AIX 5.1, compiled with xlf95
Graph of benchmarks
The results of these tests are interesting.The fastest machines are the Athlon64 and the G5, in many cases the G5 is substantially faster. This is due to the use of the Altivec unit on the G4/G5 that can deliver massive performance increases with just a few pieces of code. Thex exp() function is fastest on the Athlon64 and the Intel CPUs as long as they do not produce underflows. The Power3 and Power4 systems are lacking behind, however, they are still nearly 5 times faster for I/O (this does not show up in these tests). The performance of the Itanium2 is a total mystery to me, the result of the bench.f test for the Itanium2 is extremely good but the performance of the PHOENIX runs is extremely poor. Furthermore, some tests could not run (crashed). To get optimal performance out of a G5 you must use the Altivec unit in the most time consuming parts of the code, the speed-ups are staggering. The Athlon64/Opterons do not need special coding and have overall very good performance.

These are not practical numbers. Show me Photoshop, After Effects and 3D app benchmarks utilizing the latest processors. In all fairness to intel they should of at least utilized the latest P4.

Errr... these are scientific benchmarks... for scientists who couldn't care less about After Effects. And when was the last time you ran After Effects on POWER3 and Itanium2?

Pwned.
Yeah, cool for the science folks.

Amazing, a benchmark Prescott actually is decent at  . Also it looks like only a few of the subtests get much out of SMP.

I agree, these numbers are meaningless. How fast will they be in writing my thesis?

Yes, I know I could buy a PC, but why?
