Mobility Radeon HD 4570 Sneaks In
Close to ten days before ATI's Mobility Radeon HD 4000 series rolls out at the upcoming CeBIT event, one of its eggs seems to have hatched a little early. Dell's Indian website has already started listing it in the specifications of the Studio 15 notebook. Enter Mobility Radeon HD 4570. This mGPU is derived from the 55 nm RV710 graphics processor, and intends to be a handy performance boost over integrated graphics. It features 80 stream processors, 8 texture memory units, and 4 raster operations units. It connects to GDDR3, DDR2 memory using its 64-bit wide memory bus. The card used in Dell's Studio 15 sports 256 MB of memory. The mGPU is expected to outperform competing NVIDIA G110M by 20~30%, while keeping its TDP rating at a mere 13 W. Once formally announced, one could expect to hear more about this mGPU.

waiting on this before I buy a laptop
although I did find one that's a 1080p screen + bluray drive + C2D + 9200GS for £600...should I wait>?
3600s have 120
3400s have 40
I KNOW the ATI release is new
wait some more, this might be the low end, an replacement for my x1900m mxm 3 is coming up ;-P
For $100 more I could upgrade to an ATI mobility 4570 .
Is it worth it? How much faster? 10%????
When the lady from Dell called, she said she could upgrade but her info said I could only upgrade to a T3850. What the heck is going on? Is that the same as the 4570?

4500MHD = 900 Marks in 3d06
HD 4570 = 3000 Marks in 3d06
So its at least 2-3 (200-300%) faster than the GMA 4500MHD.
As for the T3850, that sounds like an Intel processor not a GPU. The HD 4570 is only available on the Dell Studio 1555 afaik.
