Synthetic CPU Performance
When it comes to raw CPU performance, it is kind of trivial that there are hardly any differences between the different platforms or FSB / latency settings
SiSoft Multimedia
SiSoft Sandra Multimedia CPU benchmark: Integer iSSE2 [it/s]: 2.4 = 2.4 GHz, 2.53 = 2.53 GHz; -100, -133: FSB; /SPD: DDR333 at SPD settings; /800 PC800 RDRAM; /1066: PC1066 RDRAM; /146: The 2.53 GHz P4 was overclocked to 146 MHz FSB / 183 MHz DRAM frequency (2775 MHz) on the ASUS P4S333. Aside from the clock speed, nothing else matters.
SiSoft Sandra Multimedia CPU benchmark: Floating-Point iSSE2 [it/s]: 2.4 = 2.4 GHz, 2.53 = 2.53 GHz; -100, -133: FSB; /SPD: DDR333 at SPD settings; /800 PC800 RDRAM; /1066: PC1066 RDRAM; /146: The 2.53 GHz P4 was overclocked to 146 MHz FSB / 183 MHz DRAM frequency (2775 MHz) on the ASUS P4S333. Again, from a Rambus-hater standpoint, it would be nice to see the RDRAM i850E chipset consistently perform at the bottom of the group but the performance delta is simply non-existent.
SiSoft Arithmetic
SiSoft Sandra Dhrystone ALU [MIPS]: 2.4 = 2.4 GHz, 2.53 = 2.53 GHz; -100, -133: FSB; /SPD: DDR333 at SPD settings; /800 PC800 RDRAM; /1066: PC1066 RDRAM; /146: The 2.53 GHz P4 was overclocked to 146 MHz FSB / 183 MHz DRAM frequency (2775 MHz) on the ASUS P4S333. There are minor differences in the Dhrystone scores but personally I still consider those as "in the noise". The Whetstone scores showed the same trimodal distribution as the MMX benchmarks shown above.
Boring... but necessary to show that all other differences are not caused by CPU power but by the proper interfacing of the CPU with the rest of the system.
