The NVIDIA GeForce GTX 980 Review: Maxwell Mark 2
by Ryan Smith on September 18, 2014 10:30 PM ESTBattlefield 4
Our latest addition to our benchmark suite and our current major multiplayer action game of our benchmark suite is Battlefield 4, DICE’s 2013 multiplayer military shooter. After a rocky start, Battlefield 4 has finally reached a point where it’s stable enough for benchmark use, giving us the ability to profile one of the most popular and strenuous shooters out there. As these benchmarks are from single player mode, based on our experiences our rule of thumb here is that multiplayer framerates will dip to half our single player framerates, which means a card needs to be able to average at least 60fps if it’s to be able to hold up in multiplayer.
Battlefield 4 is one of our tougher games, especially with the bar set at 60fps to give us enough headroom for multiplayer performance. To that end the GTX 980 turns in another solid performance, though the dream of averaging 60fps at 1440p Ultra is going to have to wait just a bit longer to be answered.
Overall on a competitive basis the GTX 980 looks very strong. Against the GTX 780 Ti it further improves on performance by 8-13%, 30%+ against GTX 780, and 66% against GTX 680. Similarly it fares well against AMD’s cards – even with their Mantle performance advantage – with the exception of one case: 4K at Medium quality. With maximum quality settings, at all resolutions the GTX 980 can outperform AMD’s best by around 15%. But in the case of 4K Medium, with the lesser shader overhead in particular the R9 290XU gets to pull ahead thanks to Mantle. At this point NVIDIA is losing by just 4%, but it goes to show how close the race between these two cards is going to be at times and why AMD is never too far behind NVIDIA in several of these games.
In any case for Ultra quality you’re looking at the GTX 980 being enough for 1080p and even 1440p if you flex the 60fps rule a bit. 4K at these settings though is going to be the domain of multi-GPU setups.
Meanwhile delta percentage performance is extremely strong here. Everyone, incuding the GTX 980, is well below 3%.

Different tests, different results. That's nothing new.kron123456789 - Friday, September 19, 2014 - link
But, i still think that Nvidia isn't understated TDP of the 980 and 970.Friendly0Fire - Friday, September 19, 2014 - link
Misleading. If a card pumps out more frames (which the 980 most certainly does), it's going to drive up requirements for every other part of the system, AND it's going to obviously draw its maximum possible power. If you were to lock the framerate to a fixed value that all GPUs could reach the power savings would be more evident.Also, TDP is the heat generation, as has been said earlier here, which is correlated but not equal to power draw. Heat is waste energy, so the less heat you put out the more energy you actually use to work. All this means is that (surprise surprise) the Maxwell 2 cards are a lot more efficient than AMD's GCN.

"TDP is the heat generation, as has been said earlier here, which is correlated but not equal to power draw."The GPU is a system which consumes energy. Since the GPU does not use that energy to create mass (materialization) or chemical bonds (battery), where the energy goes is easily observed from the outside.
1) waste heat
2) moving air mass through the heatsink (fan)
3) signalling over connects (PCIe and monitor cable)
4) EM waves
5) degradation/burning out of card's components (GPU silicon damage, fan bearing wear etc.)
And that's it. The 1) is very dominant compared to the rest. There's no "hidden" work being done by the card. It would be against the law of conservation of energy (which is still valid, as far as I know).

That's a misunderstanding of what TDP has to do with desktop cards. Now for mobile stuff, that's great. But the bottlenecks for "Maxwell 2" isn't in TDP, it's in clockspeeds. Meaning the efficiency argument is useless if the end user doesn't care.Now, for certain fields the end user cares very much. Miners have apparently all moved onto ASIC stuff, but for other compute workloads any end user is going to choose NVIDIA currently, just to save on their electricity bill. For the consumer end user, TDP doesn't matter nearly as much unless you're really "Green" conscious or something. In that case AMD's 1 year old 290x competes on price for performance, and whatever AMD's update is it will do better.
It's hardly a death knell of AMD, not the best thing considering they were just outclassed for corporate type compute work. But for your typical consumer end user they aren't going to see any difference unless they're a fanboy one way or another, and why bother going after a strongly biased market like that?

While it's a fair argument that unless you're environmentally inclined the energy savings from lower TDP don't matter, I'd say a lot more people do care about reduced noise and heat. People generally might not care about saving $30 a year on their electricity bill, but why would you choose a hotter noisier component when there's no price or performance benefit to that choice.AMD GPUs now mirror the CPU situation where you can get close to performance parity if you're willing to accept a fairly large (~100W) power increase. Without heavy price incentives it's hard to convince the consumer to tolerate what is jokingly termed the "space heater" or "wind turbine" inconvenience that the AMD product presents.

actually the gpu's from amd do not mirror the cpu situation at all. amd' fx 9xxx with the huge tdp and all gets so outperformed by even the i7-4790k on almost everything and the 8 core i7-5960x obliterates it in everything, the performance of it's cpu's are NOT close to intels performance even with 100 extra watts. At least with the GPU's the performance is close to nvidias even if the power usage is not.TLDR amd's gpu situation does not mirror is cpu situation. cpu situation is far worse.

I as a consumer greatly care about the efficinecy and tdp and heat and noise not just the performance. I do not like hearing my PC. I switched to all noctua fans, all ssd storage, and platinum rated psu that only turns on its fan over 500 watts load. The only noise coming from my PC is my radeon 5870 card basically. So the fact this GPU is super quiet means no matter what amd does performance wise if it cant keep up noise wise they lose a sale with me as i'm sure many others.And im not a fanboy of either company i chose the 5870 over the gtx 480 when nvidia botched that card and made it a loud hot behemoth. And i'll just as quickly ditch amd for nvidia for the same reason.

"For the consumer end user, TDP doesn't matter nearly as much unless you're really "Green""Or live in a country where taxes make up 75% of your power bill \
