We have been watching the mobile processor space for a while now with some interest, wondering whether the Turion 64 really matches up well against the Pentium M. The Pentium M's power-saving features and performance per watt are the stuff of modern legend. AMD has done well with Opteron in servers and the Athlon 64 in desktops, but surely AMD's K8-derived mobile competitor doesn't match up with the likes of the Pentium M. Does it? Well, we wanted to find out before the game changes again. Intel's recently announced Core Duo marks the beginning of a transition to multicore processors in the mobile space, and AMD has stated its intention to make a dual-core version of the Turion, as well. Core Duo laptops are just starting to arrive on the market, although volumes are still somewhat limited. With that in mind, let's take a quick look at the two most widely available mobile processors today: the Pentium M versus the Turion 64.
