battery life difference between Turion X2 and Core 2

I'll probably never take full advantage of either CPU's processing capabilities, so the only selling point for me is battery life. I know that Core 2 CPU's offer better battery life than Turion 64 X2, but how much better?

 

I think the battery life and performance ratio for the Core 2 Duo will beat the Turion X2 hands down. It won't have as good a battery life as Duo Core, but it will trade in a tiny bit of battery life for much better performance. Only problem with Duo is that it only has a 533Mhz (I think) FSB, 32-bit only, and lacks some of the features (like SSSE3 and Active Management Technology).

I would recommend just getting a Core 2 Duo so you'll have a good battery life (get a 12 cell if you need it) and be set for the future.

 

For a C2D and a comparable Turion 64 CPU in terms of clock speed, how much bettery battery life would the Core 2 offer?

(ie. dv2000t vs. dv2000z, etc.)

 

Hi.

only the early CoreDuo processors were 533mhz the T2050, T2050, all the rest are 667mhz

I have an T2050 as my laptop is 533mhz or 800mhz, I dont know what happened to 667mhz can you belive it.

For a shared memory GPU notebook, you'll get better battery life from the C2D at the expense of a much weaker Intel GPU. For a dedicated memory GPU notebook the battery life difference narrows dramatically.

Performance for the C2D is better... on benchmarks, thanks to the massive L2 caches Intel uses to compensate for their lack of an integrated memory controller and HyperTransport, and only until you factor in cost.

Real world, the combination of an AMD CPU free of the Intel marketing tax and much better AMD/ATI or NVIDIA GPU is often a better choice.

 

I was thinking along the same lines. Are you saying that a Turion X2 paired with a GeForce 6150 (IGP) will have better battery life than a comparable Core 2 Duo paired with a GeForce 7200 (128mb dedicated/ 128mb shared)? I honestly still can't figure out whether or not to choose a dv2000z or a dv2000t because I've heard horrible things about battery life on the dv2000z (~2 hours). Would a dv2000t get about 3 hrs? I've tried combing the reviews on this site, but all of them offer conflicting reports of battery life.

 

If you really want to save battery life and still get the performance of Core 2 Duo, I think you would want the new Santa Rosa based laptops ( http://en.wikipedia.org/wiki/Centrino). Most of the improvements are aimed at power saving (dynamic FSB switching, flash memory caching (versus powering up the hard drive) as a solid state memory, enhanced sleep state, and IDA). It also has a really good integrated gpu (big leap from GMA 950). You can recognize it by looking for laptops with a 800Mhz FSB.

It might be pricey for awhile, but, at the very least, it will drive the cost down for all the past platforms. I got the Napa platform just a week ago at a great deal thanks to the lower price.

 

Yes, I'm actually waiting for Santa Rosa to come out just so I could by the current tech at a lower price. I have no true interest in Santa Rosa.

 

Yeah, if you are plugged in most of the time and don't game much then the Turion is a good choice to save money. I would personally always get Core 2 Duo because its performance is better and battery life is better. Intel is quite ahead in terms of performance and battery life in the mobile segment.

 

Well, for starters, what is the battery life on a dv2000z (AMD)? Is it that horrible?

Is it possible that the crappy battery life in the 'z' version is the workings of the GeForce 6150? Even though it is integrated, it might be more demanding than the GMA 950?

I'm contemplating getting a 't' version with the GeForce 7200 Go. How adverse an effect will the 7200 have on the battery life? Are we talking a half-an-hour difference or more?

 

The GeForce 6150 is definitely more demanding than the GMA950, partially because it's a much better GPU and partially because NVIDIA isn't all that good at power efficiency yet. I have high hopes for the AMD/ATI 690M chipset.

 

I have a dv2138xx T56 x2. My battery life set at max battery with wireless is around 2:30

 

You mean max brightness right? That's pretty good then! This is on Vista or XP?

 

Medium brightness with XP, max battery.

 

Medium brightness with XP, max battery. With 12 cell can hit 5hrs
