To test power consumption today we are using a Keithley Integra unit and we measure power consumption from the VGA card inputs, not the system wide drain. We measure results while gaming in Tomb Raider at 4k resolution and the synthetic stress test Furmark – recording both results.
The Maxwell architecture is extremely power efficient – seen before with the excellent GTX750 ti, which took all the power it needed from the PCI e slot.
The Nvidia reference GTX980 demands 158 watts total when gaming – when this is directly compared to the R9 290/X (225/237 watts respectively) you can see how far ahead Nvidia are in this regard.
I’m not too excited about this gen.. I was expecting alot more from maxwell. Either way I will own the card when it comes out. I would like to see what the card actually performs like myself and see if the new features can bring it to Amd’s IQ level..
Waiting for the Next Gen Volta
How is this card running cool? Look at the reported temps it is the hottest of all tested. Across all reviews it averages roughly 73-75 degrees gaming and higher under extreme loads. If you were to overclock it, it would be extremely hot, reference r9 290x hot, way too hot!
And you haven’t taken fan speed into consideration. Turning the fan up to 100% on a reference high end GTX is still very much bearable in terms of noise. Extra fan noise for extra performance and stable temps. That’s how it always goes. Unlike the 290x that was a searing, red hot 95c at STOCK and ridiculously loud fans from AMD’s shitty reference design. If you want to keep those overclocks quiet then you buy an third party design. No one should ever intend to run a reference card overclocked off its balls anyway. Stop whining.
In sli the top card will be at the 90+ degree mark, no overclock. Just look at the numbers. Fan speed will not correct this. The really interesting card in all of this is the 970. I think it represents a revolution in price/performance, while the 980 cards are overkill for low res and just as incapable as all the others at multi display and/or 4K resolutions. The 20nm or sub 20nm cards are only a year or so away. As for stop whining, are you emotionally invested in a simple bit of conjecture? Its ok to have an opinion without espousing childishness.
Now you can read the most recent owner reviews on newegg and see how true my comments were in actual practice. This is not a jab. It is just a continuance of a prior conversation. Please do not get upset.
