Today sees the launch of Intel's fastest mobile processor, the Pentium 4-M running at 2GHz. This brings notebook clockspeeds ever closer to their desktop counterparts, reflecting a move to bring more power to portable PCs.

Intel claims that using a Mobile P4 will increase battery life and performance. Battery life is improved by the use of SpeedStep technology, which regulates how much power the processor draws according to whether the notebook is battery or mains powered.

As for performance, while the Pentium 4 processor has failed to offer real speed gains on the desktop, the P4-M does take the lead when it comes to mobile CPUs.

But to find out how this latest version lives up to this reputation, we tested a Hi-Grade Notino R5400 which uses the new processor. To see the results we got click here.

Other processors launched today include a 1.9GHz P4-M and 1.5, 1.4 and 1.33GHz Mobile Celeron chips. All are based on the 0.13micron technology.
