Nvidia Announces 480M Fermi GPU for Notebooks
Fermi power comes to notebooks.
Earlier this year, Nvidia unleashed its DirectX 11 offerings on the desktop world with the GeForce GTX 480 and 470. Now the company is spreading the Fermi technology to the mobile segment.
Today Nvidia officially announced the GeForce GTX 480M, which it touts as the world's fastest notebook GPU and "DirectX 11 done right" with hardware tessellation support.
"GeForce GTX 480M delivers nearly three times more Nvidia CUDA cores over previous generation Notebook GPUs, which means users get unbelievably fast video transcoding, upscaling from standard definition to high definition and real-time movie clean-up with the click of a button," Nvidia's Matt Wuebbling wrote in a blog post.

Yes yes very impressive. But how hot nvidia.
I didn't think they could do it mobile by cutting so few cores.
Hope they could lower voltage that much to allow mobile power constraints.
These specs are still rather impressive and Fermi is already terrible when it comes to power and heat.
For this to be even remotely useful in notebooks, the mobile architecture has to be completely different from the desktop one.
If you look at just how hot and noisy it is in a well ventilated full tower and how much power it consumes, it just can't work in a laptop where power is in limited supply and cooling even more so. And with Fermi's heat, the 'lap' in laptop is out of the question as well...
Hey, maybe they'll follow on from the GTX 480 design, and turn the bottom of the laptop itself into a heatsink!
So you're saying my laptop can also act as a portable stove now?
Im just waiting for reports of people getting burns from their laptops now... on a more serious note, if they pull it off without that many problems this could be a very impressive especially coupled with Optimus tech.
I can see shades of the laptop gpu failure they had with the 600 series where HP,Dell and many others ahd laptops failing by the thousands.....
Well holy-crap. Nvidia must be thanking their lucky stars for Toms comments - I can't imagine they'd have thought of such bleedin' obvious problems themselves...
/sarcasm off
Burn Baby Burn!!
"DirectX 11 done right"
Maybe, but ATi's solutions do more with less, and without creating a fire risk.
The detail looks amazing. I imagine a time when a high end card gives the same frames per second as a low end card but the tesselation levels are adjusted in real time so on the high end card things just look so much sweeter
I held out for ages to upgrade to a 480. Then on release I found it would not be practical as I wanted 2. I have a coolermaster stacker case with uprated cooling and 1000W power supply. Now they are going to put something from the same line in a laptop.
Personally my laptop is a tool I use intensively for business. I cant afford it to cause problems with heat or power, so I think I will pass on any laptop with this in it when we next come round to upgrading our laptops unless they release new more efficient chips. Anyone can crack a walnut with a sledgehammer. Trowing 100s of watts or power and massive temperatures at the problem of graphics processing was not the right choice in my view.
On the other hand... they do say hot "laptops" on the lap do seriously reduce you fertility (in men). I your not planning on having a family this will certainly be the laptop for you. If you dont mind 2nd degrees burns while answering your email.
