Intel has shown off a 4GHz version of the Pentium 4 processor -- almost twice as fast as the current top-of-the-range chip -- and will add hyperthreading technology that makes one processor work as two. Intel chips are getting faster at a rate of 25MHz a week, and one day it should be 25MHz per day. Other changes to PC design are being proposed in the TideWater design. (This week, Intel is having one of its regular IDF conferences for hardware and software developers. WinHEC, the real Windows Hardware Engineering Conference, will be held in April in Seattle.)
