Coming soon: 233-MHz MMX notebook PCs

Leading vendors such as Compaq Computer Corp., Dell Computer Corp., Gateway 2000 Inc.,
IBM Corp. and Toshiba America Information Systems Inc. plan to upgrade their notebook
computers for government buyers as early as October.


Formerly code-named Tillamook, the chips had 20 percent to 30 percent faster
performance on Intel benchmarks than the 166-MHz Pentium MMX did. The 166-MHz chip was
until now the fastest processor for mobile computers.


Tillamook processors consume about 40 percent less energy than their predecessors
because the core voltage has dropped to 1.8 volts from 2.45 volts.


Input/output power also has fallen to 2.5 volts from 3.3 volts.


But the increase in battery life is reportedly negligible--about 20 minutes longer per
lithium-ion battery recharge.


That's because the notebook processor draws far less battery power than the hard drive,
display, CD-ROM drive and other components.


The Tillamook processors are made using a 0.25-micron fabrication process.


The chips have a doubled 32K on-chip cache and other enhancements to maximize
processing speed.
