Low power chip battle

Intel Corp. looks to trump Transmeta's Crusoe chip with a pair of CPUs it claims run faster and use less power. Designed for notebook PCs that need all the power they can get, the 500-MHz Ultra Low Voltage Mobile Pentium III with SpeedStep consumes a mere 1 watt at full power and less than 0.5 watt in its 300-MHz battery-optimized mode. The 500-MHz Celeron lacks SpeedStep but uses less than 1 watt as well. IBM Corp. has begun to ship the first notebooks with the new Ultra Low Voltage Mobile PIII--a ThinkPad I-Series 1124--in Japan.
