Intel 875P chipset is intended for workstations and supports special Turbo Mode (now we should call it Performance Acceleration Technology) that is available in case of 800MHz Quad Pumped Bus and PC3200 (DDR400) memory and will ensure a tangible performance increase in most widely spread benchmarks and applications. The idea of the Turbo Mode implies a better optimized interaction with the memory subsystem by removing a few stages from the memory addressing procedures and will also use more aggressive memory timings. Performance Acceleration Technology of Canterwood resembles the Super Bypass Mode implemented in AMD750 chipsets. Eventually PAT may also be implemented in chipsets for mainstream computers when Intel decides that it is necessary.

What is a bit funny is that PAT abbreviation is written like the short-name of Mr. Patrick P. Gelsinger, who is Senior Vice President and Chief Technology Officer of Intel Corporation and who simply calls himself Pat, as I found over here. Gelsinger leads Intel's Corporate Technology Group, which encompasses many Intel research activities, including leading Intel Labs and Intel Research, and driving industry alignment with these technologies and initiatives. As CTO, he coordinates Intel's longer-term research efforts and helps ensure consistency from Intel's emerging computing, networking and communications products and technologies.

Maybe some Intel folks decided to imprint the name of their boss as one of Intel’s technology advantages? Who knows? :-)
