Introduction

ATi RD600 is ATi's upcoming chipset that supports the Intel Core 2 Duo and Core 2 Extreme processors. Just like its AMD equivalent, a single chipset RD600 can be paired with the South bridge SB600 for utmost performance. CrossFire performance will be greatly enhanced with its Xpress route within the chipset itself, supporting Dual Channel PCIe.

Although there are many ways to improve performance, ATI's goal is to push for higher CLK running in SYNC with the Memory. Some of the other methods include FSB/HTT Link, Memory Freq (via higher FSB/HTT or RAM divider), Memory timings, overclocking the PCIe bus and video cards.

According to information we gathered, the final revision will enhance ASync memory. Currently, with a similarly configured i975X system, the ATi RD600 performance is better due to Xpress Route which is more efficient than then Dual PCIex8.

The ATI RD600 improves the performance with

Independant memory overclocking
Automatic PCIe Overclocking with ATI video cards
Flexible software control over FSB / RAM / PCie
DDR2 1066MHzsupport
Enhanced peer to peer performance
1T Command rate for Single-rank DIMMs

The 90nm process enables low heat output. Passive cooling gives RD600 board designers can make 0 db noise designs.
