Turion 64 uses less electricity at idle than Pentium M

Both are great chips. Except one gives you outstanding integer performance, floating point performance and 64bit performance for free. Plus you don't have to worry about a usb device sucking killing your battery life.

"The power consumption tests are actually very interesting. While it's true that the Pentium M beats the Turion 64 by a substantial margin under load, the fact is that typical laptop usage leaves the system at idle the vast majority of the time. At idle, the Turion 64 system actually comes in with slightly lower power consumption than the Pentium M rig. This result indicates that, depending on usage patterns, the Turion could prove a worthy alternative to the Pentium M in terms of battery life."

"From a power consumption perspective, the Turion 64 surprised me. Yes, our Turion 64 test system consumed a third more power than the Pentium M system at 100% CPU load, but unless you're using your laptop to crunch that F@H work unit on the plane, maximum power consumption isn't usually all that important. For typical use, it seems likely the Turion 64 would be competitive with the Pentium M on the battery life front, as well."

but if you put it to normal daily use the P-M will turn up ahead, ie consuming less, since the difference at 100% (load) is more prominent than at idle.

Anyway I don't think this is a very fair comparison. It would be better to compare the whole platform, ie with chipset. If the chipset were to be factored in, the Turion platform might show as more efficient (memory controller on CPU already acounted for powerwise).

BUT there are quite a few laptops out there with identical features except for the CPU/chipset, and the P-M still manages to come ahead with regards to battery life.

Let's see what the next round will bring!

 

Interesting,

Not that interesting, but somewhat interesting, seems the 25W Turion has been good for some time, of course trying to find a decent laptop with it in is next to impossible, and it still has the issue of if/when 64bit software is going to actually matter, I'd still place a bet on 64bit not being useful to most users for at least another 3 or 4 years.

 

I have read that article and some tests won PM and some Turion. Interestingly games performance was on PM 2.0 GHz side. I think that each has its own advantages.
But the reason for this post is actually the USB issue you mentioned 64bit. Although many think it is strictly the Intel platform problem, unfortunately it seems that it is the Windows problem affecting all platforms. Fix is actually the registry entry.

And I recommend reading the whole article, many interesting things can be found.

Cheers,

 

Unfortunately no-one seems to have tried the tests on a Turion (of any sort) so it may be an Intel/Microsoft issue, or it may be a microsoft (alone) issue, until someone does the tests with a Turion (and currently the main problem seemed to be getting a performance monitor to watch the equivalent of the Intel C3 state on an AMD).

So... maybe 64Bit can provide one since he works for AMD?

 

I wrote this in your other thread, but seeing as you have a tendancy to post multiple time I will have the decency to do the same.

According to your source, the Turion has lower power consumption by just 6% when idle, is that even outside of the margin of error? The article does not attribute any gains in battery life to this lower power consumption. In addition to that, under load the Pentium M consumes a wopping 32% less power. Do you really want to argue that the Turion has lower power consumption that the Pentium M? Also, the Core Duo is suppose to have lower overall power consumption than the Pentium M.

 

This came up in LaptopLogic's review of the two CPUs - the Turion beats the P-M at its own game. However, nobody buys a notebook just to let it sit there - you're probably going to be doing something with it, and in that case, the P-M outfoxes the Turion.

 

may i ask you are so against Intel and so for AMD???

you keep trying to prove AMD's superiority...

i really hope you don't work for AMD, and this is their new marketing strategy.

your point proves next to nothing, and the whole USB power consumtion thing is a windows issue not an Intel issue.

are you done yet?..........
