NVIDIA Geforce GTX 660M Release Information + CUDA Core Count

Desktop cards let you adjust that.....

Yes thats the reason why 650M have higher TDP because it reach higher clocks than 640M. I am not shure if Nvidia have built a turbo design that throttles down after a while though because of heat. I hope not.

With desktop cards you can pretty much do whatever you want as long as you have proper cooling. Notebooks have a very small overclocking limit due to the small and compact design. Oh god how I wish this could come soon

TDP is important for GPU Boost. If the 640M has 25W TDP, 650M has 35W TDP, for example, then 650M will boost for longer and at higher clock speeds.

That is a good point I think a lot of people overlook.

Question is: Will the TDP be configurable? Arrandale was fun...

The reason I'm asking is because for the laptop that I'm waiting to be refreshed with Kepler cores, TDP is the limiting factor. So if I know the TDP of the 660m, then I know if there's a good chance if it will be in the refresh.
So again, any information on where the first place will be to have that information?

What laptop is that?

[maliusmaximus]

m14x r1, being upgraded to r2. But don't pay attention to that. I just want to know where the latest info on TDPs will be posted

There is no definite TDP, but there are some estimates:

Aren't you forgetting something? The new Kepler GPUs all have improved AA features that will maintain AA quality with lower performance loss, called FXAA and TXAA. They can also work together with traditional AA, making games look even better. FXAA is available regardless of the GPU brand, but TXAA is restricted to nVIDIA GPUs as of yet and needs to be implemented in the games. The improved features of the 600 series are hardware related.

"For example if a game is performing poorly because 2X, or 4X, or 8X AA is reducing performance by a great deal, just turn on FXAA instead and get 4X AA image quality at no performance hit".

"The first slide above shows you how NVIDIA has positioned the performance and image quality of TXAA. With TXAA 1 enabled NVIDIA claims you'll get better the quality of 8X MSAA (or slightly better) but at the same performance level of 2X MSAA".

This is shown to actually be true or at least within the performance promised by nVIDIA.

I am curious if this will be an "Always On" Feature of 600 Kepler parts?
