If you've ever with using a Pentium M on a desktop, you were likely overjoyed by the performance gained and reduction in heat once you did get it installed. Pentium Ms proved to be such performance beasts with low power dissapation that now many are wondering what a Turion 64 will behave like in the same scenario. There's a pretty detailed walkthrough covering just this, and despite owning AMD64 systems I never pondered this. Looking over the MT-32, 37, 40 and 44 modules, all socket 754 Turions, the article goes into what you could actually gain in switching or building a desktop system with a mobile processor.
What is interesting to me is that the newer Turions, though based on a 754 pin interface, are actually using a newer core revision which is primarily only available in a 939 pin package. Indeed, it seems a Turion may be a suitable upgrade path for people who jumped on A64 early and are stuck with a lower end model. On top of that, even the fastest of the ML series at speeds >2GHz are dissapating a mere 35W, and the MTs are dissapating 25W, a third of the power of other A64s. Even better, the fastest turion, ML-44, is significantly cheaper than the equivalent Pentium M, on top of running at a faster clock speed. Forget adapters or chipset compatibility as well, as Turion proves that it's fairly easy to make the switch from mobile to desktop. There are some issues with heatsinks, so research is neccessary. Overall, it's worth a look if you are looking for a low power desktop. Read the full article for more details.
