Dell Computer is offering an unannounced 3.06-GHz Xeon processor from Intel for Precision workstations on its Web site. The chip features a 533-MHz front-side bus and Intel"s hyperthreading technology, which enables a user to execute background tasks on software written in multiple threads more quickly than conventional processors can. Hyperthreading is supported only by Microsoft"s Windows XP, however, and Dell allows the buyer to order a system with hyperthreading turned off.The Precision can be configured with two processors and is sold without a monitor. So far, Intel has announced Xeon processors at speeds only up to 2.8 GHz.
