New Intel Processors: Prescott & Tejas Information

Published by

Japanese website PC Watch Impress has compiled the latest information on Intels upcoming processors. While Prescott will feature the much anticipated 800Mhz FSB, Tejas will introduce an even more impressive front side bus of 1066Mhz. Prescott is scheduled to be released in Quarter 4 this year and will be technically limited to maximum speeds around 5Ghz. Tejas, which is slated somewhere in 2004 / 2005 will reach core clocks of 4.4Ghz at launch. To position their new high-end processors Intel is improving HyperThreading technology on both processor cores as well as adding significantly more cache (Prescott: 16Kb L1 cache, 1Mb L2 cache).
