Well, I don't think anybody would agree that the Pentium-M is poorly designed, AMD fanboy or not... as for the Uniwill, I have no idea. Considering the Pentium-M clocks down to 10W whereas the AThlon 64 the Uniwill uses clocks down to 11, and the Athlon 64 gets far more battery life, I'd say there's a lot more at work than just the processor. I have no time to look, but any of these could be attributed to the screen, chipset, RAM, wifi card, cooling, or the video card.
|Intel 915 chipset actually has a bug, that makes it use too much power. This info is off the top of my head, so can't give you too much details, but if you use Google you can find this to be true. You're still looking at the Life run, and I already explained why Turion wins in that (superior drivers).
The drivers? How so... I'm interested in learning more on this, but I was unable to find any pages that refer to this. Could you possibly see if you could find where you saw this so I could read into it?
|All I can say is... LOL
Has ANY official review ever created feature "undervolting" results? This is a mainstream review, so don't expect absurd things. And you explained it yourself: Pentium M at LOWEST CPU SPEED got 3hrs 25min. How's that suspicious?
As for the undervolting, its just one means of extending battery life. True, almost all reviews don't do it; but then, most reviews don't under/overclock their video cards and switch out memory. I figured since it was alright to optimize the notebooks, undervolting was in the same ballpark.
|This is kinda obvious. DDR400 CAS2.5 is the STANDARD for Turion. DDR533 CAS4 is the STANDARD for Dothan. Acer was just being miserly pricks by choosing to go with DDR333.
But the difference here is, they replaced
--as in took out what was provided and put in their own preference--the RAM in the Ferrari. In other words, they used the most efficient memory. So to be fair, why didn't they do the same for the Pentium-M? There's faster memory available for it as well, which indicates they showed a definite preference to the Turion.
That being said, I'm liking the Turion more and more, but I'm not really liking where its available. I love AMD processors for the desktop (how can you not?), but I think that benchmarking needs to be expanded for the Turion. It seems like all too few people have reviews of it, whereas you can throw a rock and hit a dozen reviews of laptops featuring the Pentium-M. Still, not looking at the components themselves, I fail to see how certain components drain less battery life even though they're using more power. That was my main problem with the review--not the fact that it was by Intel or AMD. If it is indeed some kind of bug with Intel's chipset (which is very odd, to say the least), that would open up all kinds of explanations.
runninkyle17: I'm looking forwad to the same benchmark! AMD is definitely on its way to _really_ breaking into the market and taking serious sales away from Intel. If only the larger manufacturers started using the Turion... the Thinkpad would be godly if they did! The same goes for most of the other manufacturers. Unfortunately, Dell and what not have an Intel-only agreement, which will definitely hinder their break in.
Laptop<3: The Turion isn't a faster chip? Well, it all depends on what you're looking at. I mean, if you're talking about frequencies, they're more than well-matched... if you're talking about performance, that entire subject seems to be a bunch of big unknowns. Pentium-M owners say its Intel, Turion owners say its AMD. As for the battery life... that's also very, very subjective. For one, the quality of the battery determines the length, as does heat, etc.. Plus, what if one computer uses a nicer screen while another uses a bad one? Its not at all uncommon for there to be several different screens in the same notebook line.
So in short, Turions are actually quickly rising... I think Intel has gotten real comfy with its position, and it may actually have to start really pushing for new R&D in order to run head to head with the Turion. It'll definitely be interesting to see the dual-core P-M, although it remains to be seen when and if AMD will release one sooner.
