Pascal TDP

[DrJones]

With Pascal hopefully coming out soon (I doubt June but you never know), I'm curious to hear what people have to say about the TDP of these new cards. They are said to have "2x the performance per watt" of their Maxwell counterparts.

So does this mean a new Pascal card will be able to perform the same as say a 980ti at 250W using only half the power(125W), resulting in lower temps with custom cooling solutions leaving much more headroom for high end overclocks? <---Sorry kind of a run on sentence there.

Or does this mean a Pascal card will be able to perform 2x better than the 980ti while still drawing 250W?

(I am only using the 980ti as an example)

I know we cannot possibly know this for sure yet, but I'm looking forward to seeing everyone's comments.

i'd say a slight increase in performance for about 0.6~0.7x the power consumption is more like it

 

they wont be making a card 2x more powerful as that will ruin the market for the current gen gpu, or the next gen gpu will be more costly than a titan

 

price to perf have to make sense

[-rascal-]

When they say "2x the performance per watt" it is usually the theoretical compute performance (single precision computing, FP32) .

When you translate that to gaming performance, it won't be 2x. It will be quite a bit less.

 

EDIT: You need to look at the WHOLE quote

Quote

Jen-Hsun claims that Pascal will achieve over 2x the performance per watt of Maxwell in Single Precision General Matrix multiplication. But there are two caveats to this claim, as far as gamers are concerned. First, recall that improvements to performance per watt, while certainly vital and important, are not the same thing as improvements to top-line performance. The second thing to keep in mind is that boosting the card’s SGEMM performance doesn’t necessarily tell us much about gaming.

 

And this is talking about the 'Pascal' architecture as a whole -- that includes the $5,000+ workstation monster cards that will be using 'Pascal.' 

 

When nVidia CEO, Jen-Hsun Huang, presented 'Pascal' at the Technology Conference 2016, that was NOT a GTX gaming GPU. Those were Tesla GPU's.

You can't game with those.

Oh yes, I'm aware, this is all very theoretical, but thank you for your comment. I just want to see how others think it will stack up with our current cards

1) use these gpus

2) run minesweeper

3) proven that you can indeed game on compute gpus

Both They make multiple graphics cards. They will have a high end card that draws the same amount of power with more performance, which will replace the 980 Ti price bracket, and they will have something mid-range that gets probably similar performance with less power. The GP100 chip which will replace the GM200 used in the 980 Ti has a TDP of 250-300W.

 

Most likely NVIDIA will release the mid-range chip first, with 180-200W TDP (though they will call it the GTX 1080 or whatever) as they have done with the last few generations, something that performs slightly better than the previous flagships but with a lot less power consumption, to get everyone talking about how the new cards use so much less power. Then a few months later they will release the real flagship (1080 Ti) which will consume just as much power as previous flagships but with a lot more performance.

Tesla cards don't have any display outputs on the back, so no, can't really game on those
