Default Any high end cards coming out with lower power consumption?

Will future cards be coming out with lower power consumption?

For example, would a process shrink on the GPU result in less power consumption? So that a future version of the 8800 say, would have equivalent performance but use less power?

Thank you

yes thats the general trend and reasoning behind going to smaller processes. If a g80 is die shrunk it will consume less power , but that all depends if lets say 2 shader clusters are added on top of the die shrink and or clock speeds are increased, we might not see much of change in power consumption, but an increase in performance.

Generally that's true, but it has to be done well, unless you end up with a die shrink like Intel did with the Prescott core.

But nvidia have done well on 7900 series from 7800 series. I believe it would be the same with 8800 refresh

That`s a buy argument for me too. I got a OCZ 520 Watts PSU that poweres my system just fine and has some headroom still.
It prolly would run a 8800 GTX but i can`t be sure and it would be on the edge.
I am not willing to shell out another 150 bucks fora new PSU just for a GPU update.

The CPU producers saw that problem and started working towards lower consumption. The GPU manufacturers head towards more and more power consumption atm. Not long and we`ll face megawatt PCs if it continues like this!

If i can get a refresh of the G80 with x1900 XTish power consumption and it is not a LOT slower then the R600 i know where my money will goto.

Let me ask a more specific question.

When are Nvidia and ATI coming out with cards that are manufactured with a smaller process technology? Below 90 nanometer?

i found out the 1950pro is only 80 nanometer, but 8800 is still at 90nm.

Guess these GPUs will use a lot less power when they go to 65nm, whenever that is.
Anyone know when that is?

I'm going to hold off upgrading from my crappy x800xl they do.

yes switching to a smaller process will mean it will consume less power, but then they will jack up the clockspeeds again to gain more performance, at the cost of power savings.

the quick answer to your initial question :
no, no high end cards are coming out with lower power consumption...


if power is really an issue switch to middle to low range of gfx cards
