As part of its Pentium upgrade programme, which is due to be unveiled at Comdex/Fall in Las Vegas, Intel Corp is expected to reveal details of a new process for manufacturing smaller, cooler versions of its big, hot Pentium chip. At 13 Watts, the Pentium has suffered well-documented heat dissipation problems that particularly affect small desktops and laptop systems. New 3 Volt, 0.6 micron, 100MHz Pentium iterations for laptops and notebooks are already part of Intel’s plans – the go-faster P24T OverDrive upgrade part for 80486 systems with an OverDrive socket is the one that has been causing concern – and that is not even a full Pentium.
