Frankly, though, the GeForce GTX 980's primary purpose is gaming. So to be fair, we're only looking at the card's efficiency in that context. After the launch, we'll spend more time covering the other disciplines in a follow-up story.
Maxwell does very well, even without Gigabyte’s golden sample factored in. This observation is based on the power consumption measurements in our 2014 VGA charts. If Nvidia's reference GeForce GTX 980 sets the bar at 100 percent, then all of the other Maxwell-based cards fall in line right above it. Non-Maxwell-based boards show up below. Not surprisingly, Gigabyte’s golden sample ends up at the top, and even manages to pass a GeForce GTX 750 in the process, which is no small feat for a card built using a large GPU.
Thinking back to the maximum versus average power consumption findings for gaming, one fact becomes abundantly clear: AMD’s issue is not absolute performance or the efficiency of its architecture, but rather that PowerTune technology can’t adjust the power consumption quickly or finely enough depending on the actual load. This is exactly where Nvidia scores most of its points with Maxwell.
But even Nvidia can’t change the laws of physics. The new cards’ power consumption during compute-based testing demonstrates this fact very clearly. There are some ways around these laws, however, and the company's engineers seem to have found them. A gamer would say that they simply have the better skills.

Good stuff here - but you guys were a bit slow on this one. Tom's Hardware is the first site I visit every morning. But with the delay of this article, I've been all over the net this morning on other sites that got their stuff out sooner.
I was hoping for more performance but the efficiency is quite nice. They just put pressure on the top end and gave us a price reduction, instead of overall performance gains.
Likely, we're going to see a Maxwell Titan equivalent come in the next year or so as these are a x04 much like Kepler with the 670/80s were and we're still going to be waiting to see what the x10 will be with the Maxwell architecture.

That's some flat out insane price / performance ratio right there!
Same answer to both... no time.
We literally got the 970 for testing yesterday. The 980, we got the day before. We barely got the article out by this morning.
For those of you who want more info, we'll be spending more time with the GeForce GTX 980 and 970 in the weeks to come, don't you worry.
I'm waiting for the real Maximum Maxwell myself. Unimpressed with these xxx04 launches from Nvidia.

Depending on resolution, dual 970's are roughly equal to the 295x2 at only 2/3's the price.
The features that Nvidia has been rolling out constantly has been quite impressive, while many of them do not appeal to me at all, the sheer amount and in most cases quality of them is insane.
Well done Nvidia. Let's see what AMD responds with, my next main gaming machine purchase as of now are 2 x Nvidia GTX970.
EDIT : Im sure that its a good upgrade to my 2 x HD7950s

Thank you! That answered a question I had in a previous GTX980/970 tease on the live news feed.
Do you guys have this problem often with Nvidia? You always seem to have fewer Nvidia board partner variaty and slower review releases on Nvidia GPUs.
More so than other websites.

My bets are that no NVidia GPUs on the best GPU's for the $$ for the past several months earned Tom's a slight delay in the delivery of these GPUs.

Nah, doubt Nvidia is that petty.
More publicity is exactly that, more publicity.
Tom's has been around a long time and is trusted by A LOT of people.
Doubt Nvidia would compromise the user base.
