 Quake III Arena has always been sensitive to memory bandwidth in general. Thus, it comes as no surprise that the 645 with DDR333 SDRAM edges out the DDR266 competition by 8%.
 The Return to Castle Wolfenstein MP Test also showed big improvement in scores with higher available memory bandwidth. The 645 operating in DDR333 mode was 11% faster than the DDR266 competition. However, this gain decreases under Dronez and Max Payne, ostensibly because the GeForce2 MX became the bottleneck rather than the chipset.
 3DMark2001 is also fairly sensitive to memory bandwidth, with the 645 with DDR333 SDRAM clearly leading the pack. Here, the Intel 845, which has showed strong DDR266 performance thus far, edges out both the P4X266 and 645 by 2%.
