Intel's Dothan Makes Its Late Debut

Synthetic Benchmarks

SiSoft Sandra 2003 Benchmarks: CPU, Multimedia And Memory

In order to make it easier to distinguish the two Winbook configurations from one another, we've labeled one Winbook with WB and the other Winbook with WD. The "B" in "WB" stands for Banias/1.7 GHz. And the "D" in "WD" stands for Dothan/2.0 GHz. The measurements were taken with different power schemes (Portable Laptop, Always On, Max Battery), as well as in battery-powered and power supply modes.

Dothan is faster, simply because its clock speed is 18% faster. The performance difference between the Pentium Ms with clock rates of 1.7 GHz and 1.6 GHz is marginal.

In this case, the 2 MB cache, twice the size of that on Banias, does not come into its own, either. The increase in speed corresponds almost exactly to the difference in core clock.

In memory performance, there is barely any difference between the two Winbook configurations. The Lifebook S6120, however, proves to have considerably poorer memory performance, which can be assigned to its integrated graphics without dedicated video memory. The fact that a portion of the system memory is used for image rendering naturally reduces memory bandwidth.
