Intel plans to turn up the wick on desktop PC performance Monday.
The chipmaker will announce three new Pentium 4 chips for desktop PCs, along with a new version of its 850 chipset. The new chipset offers a faster 533MHz bus and supports a speedier version of Rambus memory, 1066MHz RDRAM, sources said.

Intel's new flagship Pentium 4 will be a 2.53GHz chip. The other new Pentium 4's will run at 2.26GHz and 2.4GHz. All work with the faster bus.

The added clock speed, faster bus and new RDRAM could translate into an overall performance boost of roughly 10 percent to 15 percent over current high-end desktop PCs, some sources have said. The bus provides a data pathway between the processor and memory. Maintaining a proper ratio between the bus speed and the clock speed of the processor is an important element for preserving performance as processors get quicker.
