Who cares about power consumption if it's slow (even if it's not, in the "top performance" card)?
Who cares? People who want to use a small form factor case instead of a giant full tower. OEMs who don't want to have to spec out bigger power supplies just to offer a video card upgrade.
Once Quadro comes around, businesses that rely heavily on GPUs will care, too - power consumption can really add up for them.
I'd be surprised if Apple didn't take power usage into account when deciding which GPU vendor to go with on the next Mac Pro.
And on the other side of the coin, those that used the 470/480 sit here and pretend like a few watts suddenly mean the difference between buying a cheaper and faster card when their spons..., I mean brand is slightly more efficient. :thumbsdown:
Exactly who are we talking about here?
2048 cores, 16 SMM, not 15 SMM as many had thought. ~175W TDP.
Also GTX 970 is 148W TDP.
Those figures are actually a bit better than I had initially guessed. I wonder what we'll see for TDP on the GTX 960. If they bring it in around 100-125W, it might actually be feasible to cool that card fanlessly with something like the Accelero S1 Plus, at least if your case has decent airflow.
I think you dramatically misunderstand just how little 75 watts is.
Do you start sweating in an island of heat when you turn on a light bulb? Because one those puts out more heat than a second 6-pin would add.
Incandescent light bulbs do noticeably heat up a room. They're extremely inefficient, which is why they're in the process of being banned.
If after-market 970s can provide 92-93% of the performance of 290X at such a dramatically lower power level, combined with NV's strong brand value and NV-specific features, it'll be enough to make 290Xs irrelevant for the majority of the market (1080p and below gamers) even if AMD were to drop 290X to $400. I think AMD will need to drop 290 to $319 and 290X to $359 if a 148W 970 is $399.
After this release, the only really competitive card AMD will have on the high end will be the R9 295X. (It will continue to be the only single-board solution that can provide viable AAA gaming at 4K, with the possible exception of the three-times-as-expensive-and-not-as-good Titan Z.) Tonga, Tahiti, and single-chip Hawaii are going to have a hard time against GM204; they're going to have to rely on price drops, which is not good for AMD's bottom line. Pitcairn too will be squeezed when the GTX 960 comes along. AMD really needs to get the ball moving again or they'll lose market share rapidly.
