Asus crosses Intel with PAT compatibility claim
Asus is on course to clash with Intel over whether its Springdale-based mobo, the P4P800 offers features provided by Intel’s Canterwood chipset. 
Launched in April, Canterwood, aka the i875, offers what Intel calls Performance Enhancement Technology (PAT). Essentially, that means the chipset uses more aggressive memory timings to achieve a 3-5 per cent performance boost. Intel launched Springdale, the i865, t’other week as a lower-end alternative to Canterwood. Both chipsets support the Pentium 4 operating over a 200MHz frontside bus quad-pumped to an effective 800MHz. Yesterday, Asus announced its 865-based P4P800 Deluxe mobo shipped with the ability to turn on PAT via the company’s own BIOS. In short, with one easy tweak your 865 has become an 875 - ironic, given PAT is one of the few things that differentiates the 875 from the 865. Today, Intel dismissed Asus’ claim. A spokesman said that PAT is “hardwired” into the 875 - it can’t be enabled in the 865. “PAT cannot be enabled on a 865-based motherboard,”.
