KZNerd, re: benefits of DRDRAM at higher processor speeds

I gleaned a few things off of the benchmarks from Tom's Hardware Guide (http://www.tomshardware.com):

1) Celeron is already up to a 7:1 processor-to-bus clock ratio, and the performance improvements are still there. Soon, Celeron will go to 7.5:1, then 8:1, maybe even further. This would argue against the need for faster DRAM technology, however ...

2) Different benchmarks demonstrate different reliance on DRAM bandwidth. From most reliant on DRAM bandwidth to least:

- SSE applications such as speech recognition
- High-end Winstone 99 applications (Visual C++, Photoshop, etc.)
- Business Winstone 99 applications (MS Office, Netscape, etc.)
- Games

3) Because latency between PC66 and PC100 SDRAM is the same, going to higher clock ratios on a 100 MHz bus will see even smaller performance increases than going to higher clock ratios on a 66 MHz bus. That's why Intel probably won't go past a 6.5:1 clock ratio on a 100 MHz bus.
