Intel's 820 Chipset - Performance using SDRAM

Content Creation Winstone 2000 provides us with a good real world simulation of a multitasking environment. As you can see by the chart, the i820 equipped with SDRAM is about 3 - 6% slower than the i820 using RDRAM and about 8% slower than a regular BX with SDRAM.

The performance of the i820 with SDRAM is about on par with that of the VIA Apollo Pro 133A using SDRAM, while in some cases the 133A manages to pull ahead courtesy of its 133MHz memory bus frequency whereas even with the 150MHz FSB setting, the i820 w/ SDRAM ran the memory bus at 112MHz.
