What strikes me about these results is how, for all of the differences in architectures and the back-and-forth battles on individual tests, on the whole the two processors seem evenly matched, as evidenced by the tie on the overall WorldBench score. It seems that every place where one chip should have an advantage, it's brought back into check by another deficit. The Turion 64's on-die memory controller is hampered by the single channel DDR400 limitation, while the Pentium M's high memory bandwidth is handicapped by its slow front-side bus.

From a power consumption perspective, the Turion 64 surprised me. Yes, our Turion 64 test system consumed a third again more power than the Pentium M system at 100% CPU load, but unless you're using your laptop to crunch that F@H work unit on the plane, maximum power consumption isn't usually all that important. For typical use, it seems likely the Turion 64 would be competitive with the Pentium M on the battery life front, as well.
