GTX480m announced

[Lonyo]

the biggest shame here, is that you couldn't do optimus on it unless you pair it up with a dual core cpu...

Optimus works with Intel integrated graphics IIRC, that's one of the reasons why it should actually gain traction.
If it was NV chipset only it could never work in the market.

DTRs like the Alienware M17x and Clevo M960U used two GTX 280M in SLI.

The Clevo power brick is 220W, which is just enough considering a high end mobile proc is usually around 35W.

A single GTX 480M with a mobile Core i7 would probably need a 120W power brick. No biggie for a gaming notebook.

If the 480M/memory pulls 100W by itself as reported, you'll need more than 120W to power the entire system.

352 cores though, is it a harvested GF100?

RE: 100W!? by JarredWalton on Tuesday, May 25, 2010
NVIDIA has confirmed with me that this is a die harvested GF100. The future products aren't even out for the desktop market, so it's highly unlikely they would release first in the mobile sector. I expect we'll see mobile versions of the other GF10x chips down the road. As for the 100W... well, companies put Core i7 desktop parts into large notebooks, so why not a 100W GPU? You can fit two 285M chips in an 18.4" notebook as well, so a single 100W GPU isn't that much worse. Obviously, these aren't even remotely targeting the portable market but are after people that don't mind large, heavy, but fast notebooks.

So it seems.
