I found this quite interesting. This site has compared two Acer notebooks, the Ferrari 4005 and TravelMate 8104.

The configuration of both are identical, except for the processor, board and memory. The Athlon-based notebook uses a 2 GHz Turion with DDR333 memory on Express 200M chipset. While the Pentium-based system has a 2 GHz Dothan with DDR2 on the 915PM chipset. Everything else is the same, including amount of memory, video card, hard drive capacity etc.

They've even done an architectural comparison of the two chips. Here's a bit

Comparison

In order to correctly interpret the benchmarks, it is imperative to understand the strengths and weaknesses of the Dothan and Turion processor architectures.

Featuring brand new technology developed specifically for a high performance to power ratio, such as the accurate branch prediction, micro-ops fusion engine, and dedicated stack manager, Dothan obviously has the superior CPU architecture. In contrast, Turion is merely a slightly modified desktop/server CPU. In fact, it would make sense to call Turion a low-voltage, single-channel Athlon 64. Unfortunately, this means that many transistors are wasted on server and desktop-specific features. Due to its architecture, it is fair to assume that Turion will lose to Dothan in power consumption and heat, but we must keep a rather large detail in mind: Intel and AMD do not calculate thermal design power the same way. Intel measures TDP as the maximum power dissipated at 75% of the maximum power for a given frequency. AMD measures TDP as the maximum power dissipated when the CPU is drawing the maximum current under worst-case conditions. Thus while Intel’s numbers may be lower, and they have a lot of power optimizations, the Pentium M is not as economical as its 27W TDP suggests. Suddenly the Turion ML’s 35W TDP isn’t looking so bad, and the Turion MT’s 25W TDP is looking mighty good. Therefore, we can expect Turion to be, for the most part, competitive with Dothan. The question is where the strengths and weaknesses of each architecture lie.

The Turion performs quite well! AMD's finally showing their mettle on the notebook front. Go through the full review.

Great review! :hap2:
Looks like AMD's set to beat the pants off Mr. Intelligent! :p

i think u haven't read it carefully ...... i also a AMD fanboy(and i mean it) but in mobiles there is nothing that can beat Intel

its very difficult to catch with intel ... as u can see almost all the processor architecture are invented by intel ..... they started the concept of microprocessor .... its was really tough job giving intel some competition in that and AMD has done that even they have beated them in some fields ....

hey... in the article, The Turion is pronounced the winner except for battery life... and that too only when the proccy is running flatout all the time. But in almost all other benchies, the AMD is better..... what makes you say that Intle is still better??

Atually if u read the comments, they have waffled.

Performance is pretty much in par, you get somewhat better perf on turion, but lose out on power consumption, but price may be different.
