Today Intel will introduce their new top notch Pentium 4 CPU's running at 2.53Ghz, 2.4Ghz and 2.2Ghz. These new CPU's will take advantage of Intel's revised 850 chipset which offers 533Mhz bus speed and supports a speedier version of Rambus memory, 1066MHz RDRAM. The increased FSB mounts up to a memory bandwidth of 4.26GB/s. 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.
