Ok here we go, that 7% inrease was a i840 (dual channel RDRAM) vs. a BX 440 w/PC100 SDRAM. Here's what happens if you clock the FSB of the BX to 133. Higher is better Sysmark 2000 440BX 133 MHz FSB PC133 SDRAM 173 i840 PC800 RDRAM 171 Bryce 4 440BX 133 MHz FSB PC133 SDRAM 201 i840 PC800 RDRAM 187 Corel Draw 9 440BX 133 MHz FSB PC133 SDRAM 181 i840 PC800 RDRAM 182 Elastic Reality 440BX 133 MHz FSB PC133 SDRAM 197 i840 PC800 RDRAM 204 Excel 2000 440BX 133 MHz FSB PC133 SDRAM 171 i840 PC800 RDRAM 183 NaturallySpeaking Prof 4.0 440BX 133 MHz FSB PC133 SDRAM 201 i840 PC800 RDRAM 187 Paradox 9.0 440BX 133 MHz FSB PC133 SDRAM 173 i840 PC800 RDRAM 163 Photoshop 5.5 440BX 133 MHz FSB PC133 SDRAM 147 i840 PC800 RDRAM 142 PowerPoint 2000 440BX 133 MHz FSB PC133 SDRAM 176 i840 PC800 RDRAM 179 Premiere 5.1 440BX 133 MHz FSB PC133 SDRAM 168 i840 PC800 RDRAM 168 Windows Media Encoder 4.0 440BX 133 MHz FSB PC133 SDRAM 171 i840 PC800 RDRAM 171 Word 2000 440BX 133 MHz FSB PC133 SDRAM 148 i840 PC800 RDRAM 151 Open GL Tests AWadvs 440BX 133 MHz FSB PC133 SDRAM 77.7 fps i840 PC800 RDRAM 77.7 fps DRV-06 440BX 133 MHz FSB PC133 SDRAM 31.74 i840 PC800 RDRAM 31.43 There are some other test that favor the i840 but they are AGP4 vs. AGP2. RDRAM's only real speed advantage is in high-bandwidth video editing and unless you do your graphics in MS Office, don't expect any gains in performance. The price of RDRAM 256mb ECC chips fell $200 this past week if anyone is intrested. My point is that money spent on RDRAM is better spent on getting another machine to spread the workload around.
