Intel's chipset, formerly known as Canterwood, increases the top speed at which data travels between the memory modules and the processor from 533MHz to 800MHz. Increased front-side bus speeds allow the processor to access data stored in the main memory more quickly and more frequently, improving overall performance.
Intel's hyperthreading technology will allow the chipset to fool an operating system into believing it is running on two processors. The operating system then sends more instructions for execution, which are absorbed by unused portions of the real processor.
Hewlett-Packard, Gateway and Dell have launched desktop systems based on the new technology, with other major PC suppliers expected to follow soon.
The 875P will also introduce of dual-channel double data rate memory, known as DDR400. Most PCs with double data rate memory currently use DDR266 or DDR333, but DDR400 is catching on among high-end users that need the quickest memory technology available.
Intel has also launched a 3GHz Pentium 4 processor that supports the faster front-side bus speed. The company will add the faster front-side bus to other Pentium 4 processors by May, including the 2.6GHz and 2.8GHz Pentium 4 chips.
