The AMD chip is hands down the better choice.
I don't think there is much truth in that. In fact the performance of Dothan and Turion is very similar clock for clock. CS986's claims that "Intal is stuck using their own junk" are completely false. In fact the Intel Centrino platform only mandates the use of a Pentium M processor, an Intel motherboard, and a Intel Wireless Card, the graphics processor is separate.
ATI X700 graphics card (which you will not find with anything Intel
Well here is a perfect example of a Pentium M 750 with an X700 graphics card.

In any case, the best advice is to find a laptop with the features you like such as size, weight, graphics card, hard drive space, etc. Performance-wise the difference between an equivalent clock speed Turion and Dothan isn't very significant. The Dothan Pentium M's are faster in games, especially with the 533MHz FSB and DDR2 533. However, Turion's are faster in media encoding tasks.

It is worth noting that Pentium M labtops generally have longer battery life. This is due to the fact that not only is the processor power optimized but the motherboard and wireless card are too as part of the Centrino umbrella. DDR2 RAM uses less power as well. Of course, battery life depends a lot of the specific model as manufacturers can skew things with their choice of other components.
If you are just buying a labtop now, you should take godlyatheist's advice. Intel will be releasing the new dual core Yonah Pentium M early next year. The launch date was rumoured to be New Year's Day, but it may be pushed back to January 6. Labtops should be available quickly after that. Yonah would be a much better option as it offers 2 cores without sacrificing clock speed. The price isn't inflating either as dual-core Yonah is set to be same price point replacements of current Dothan processors. A new motherboard and Wireless card under the Napa umbrella is also set to be released. The claim is that the new Yonah and motherboard will offer 68% more performance than current Pentium M's with 28% less power consumption.

If you need a laptop right now, the difference between Turion and Pentium M isn't that significant so look at other features first. If you can wait a few weeks, then do so and get Yonah in the new year. [/quote]
