su9300/9400/9600 laptop CPU performance?

[acole1]

I have notices some new laptops, like the Latitude XT2, are now using "Intel Core 2 Duo su9300/su9400/su9600" CPU's clocked at 1.2, 1.4, and 1.6GHz respectively.

How to these compare to the Txxxx, Pxxxx, and the like C2D processors? I can't seem to find any comparable benchmarks or info.

Thanks!

"SU" ULV CPUs have a 10W TDP. "SL" low power is 17W, "P" power optimized use 25W, "T" use 35W. Quads are 35/45W AFAIK.
As far as speed, just look at the clock speeds. They are far faster than a single core atom, but not going to blow the doors off of anything desktop also based on C2D.

Im hoping for a LV CPU option on the XT3/e4210, but I doubt its going to happen, power/battery requirements and heat limits being what they are. Which is why Ill probably be picking up an e4310, rather than an e4210.

Thanks, that helps!

yeah. Intel has said they've gotten nehalem based arrandale chips down to 10W. But if they can do a 17W chip, and remove the 6-7W of heat from the northbridge at the same time, itd have be a wash. Of course, they could stick with 10W chips and bag the battery life savings.

The ULV/LV chips have the reduced from full cache amounts (2/3MB IIRC), but there is nothing special about performance compared to other chips with the same clock speed / bus speed / cache configurations.
