ScienceMark 2.0, HEXUS Pifast
Remember that we're comparing CPUs that all operate at different frequencies. The ASUS A6JA sports a 2GHz Intel Core Duo T2500, the Dell XPS Gen 2 a standard, single-core Dothan Pentium M 770 running at 2.13GHz, and the Rockdirect a desktop Pentium 4 570J clocked in at 3.8GHz. Three Intel CPUs, two of which are designed for pure mobile use, and one, the Yonah T2500, utilising dual-core technology.
Higher memory bandwidth and reduced access latency for the Centrino Duo T2500 is no surprise; it runs off a faster FSB than the Dothan-based Pentium M.
And whilst it gives away 133MHz in clock speed to the Pentium M 770, a series of internal performance optimisations make it the quickest in the single-threaded HEXUS Pifast test. A 2GHz CPU soundly thrashing a 3.8GHz Pentium 4? You can now see why Intel was so eager to move on to a processor numbering system.
