Final Words

When NVIDIA launched the first Maxwell cards earlier this year, we knew that we would be in for a treat with their latest architecture. Though just a fragment of the performance of what their eventual high-end cards would be, NVIDIA’s first Maxwell cards offered an interesting look at an architecture that would be capable of doubling NVIDIA’s performance per watt on the same 28nm TSMC manufacturing process they started with over 2 years ago. To that end I don’t think there has been any doubt that NVIDIA’s eventual second generation Maxwell cards would be equally amazing when it comes to power efficiency, but I feel NVIDIA has still impressed us when it comes to performance, features, and pricing.

In many ways it feels like this latest launch has returned us to the PC video card industry of 2012. NVIDIA’s flagship consumer card is once again powered by a smaller and more potent consumer-class x04 GPU, and once again NVIDIA is swinging the one-two punch of performance and power efficiency. When GTX 680 was launched it set a new high mark for the video card industry, and now we see GTX 980 do more of the same. The GTX 980 is faster, less power hungry, and quieter than the Radeon R9 290X, so once again NVIDIA has landed the technical trifecta. Even if we’re just looking at performance and pricing the GTX 980 is the undisputed holder of the single-GPU performance crown, besting everything else AMD and NVIDIA have to offer, and offering it at a price that while no means a steal is more than reasonable given NVIDIA’s technical and performance advantage. As such GTX 980 comes very, very close to doing to Radeon R9 290X what GTX 680 did to Radeon HD 7970 over 2 years ago.

Meanwhile from a feature perspective the GTX 900 series is going to prove to be a very captivating product. Dynamic Super Resolution is a brutish-yet-clever solution of what to do about anti-aliasing on today's deferred renderer games that cannot support traditional MSAA/SSAA, and while I’m withholding my judgment on Multi-Frame sampled Anti-Aliasing until it’s made available to users in NVIDIA’s drivers, the idea at least has merit. Otherwise I am very happy to see that NVIDIA has now fully caught up to the competition in terms of baseline API features by offering everything needed to support Direct3D 11.2 and beyond.

Along those lines, NVIDIA’s focus on voxel technology for Maxwell 2 is a very interesting route to take, and I am eagerly anticipating seeing whether it gets widely adopted and what developers do with it. VXGI is a very neat concept to generate voxel based global illumination, and building in the features necessary to do significant portions of it in hardware is a wise move by NVIDIA. The catch at this point is the same catch that faces all vendor specific technologies: just because the hardware is there doesn’t mean developers will put it to good use, especially in this age of console ports. NVIDIA for their part has made the right move by making sure VXGI will run on other hardware, but I am concerned that the performance delta means that it’s only going to be viable on Maxwell 2 GPUs for now, which could discourage developers. None the less we do need better lighting in games, and I hope this encourages developers to finally adopt these kinds of high quality global illumination systems.

As for the hardware itself, is there anything left to say other than that GTX 980 is a well-built, well-engineered card? The build quality is impeccable – raising the bar over even GTX Titan – and the power efficiency gains are truly remarkable. With a TDP lower than even GTX 680, this is the lowest power consumption has been for a chart-topping card since 9800 GTX over half a decade ago. It’s really a bit of a honeymoon period since if and when NVIDIA does Big Maxwell one has to expect power consumption will go back up, but for the time being it’s very pleasing to be able to get chart-topping performance inside of 165W. And the fact that this comes from the same company responsible for GTX 480 just 2 generations ago makes this the ultimate technical turnaround.

In conclusion, the GeForce GTX 980 represents another stellar performance from NVIDIA. Their reign at the top is not going to go unchallenged – AMD can’t match NVIDIA on performance, but they can sure drive down prices – but as was the case in 2012 the crown continues to securely reside in NVIDIA’s hands, and once again they have done the technical hard work to earn it.

Finally, as a reminder we will be following up this article next week with our look at GTX 980 SLI performance and a look at the GTX 970. Of the two cards launched today the GTX 970 is without a doubt the more interesting of the two thanks to its relatively low price compared to the performance NVIDIA is offering, but due to our aforementioned board issues we will not be able to take a look at it until next week. So until then stay tuned for the rest of our GM204 coverage.

    To Ryan Smith. How can the GTX 980 possibly have a 165W TDP when it actually consumes 8 watts more than the 195W TDP GTX 680 !? please explain ? did Nvidia just play games with the figures to make them look more impressive ?

    TDP =/= Power consumption although they are related. TDP is the amount of heat it will output.
  • Carrier - Friday, September 19, 2014 - link

    You're right, power consumption and heat output are related. That's because they're one and the same! What else could that electricity be converted to? Light? A massive magnetic field? Mechanical energy? (The fan, slightly, but the transistors aren't going anywhere.)
  • Laststop311 - Friday, September 19, 2014 - link

    no they aren't the same. Not all the electricity used is converted to heat. This is where the word EFFICIENCY comes into play. Yes it is related in a way but maxwell is more efficient with the electricity it draws using more of it and losing less of it to converted heat output. It's all in it's design.

    bullshit. since a gpu doesn't do chemical nor mechanical transformations all the energy used is converted to heat (by way of moving electrons around). efficiency in a gpu means how much energy is used for a fixed set of calculations (for example: flops)

    It's okay to be ignorant, but not ignorant and belligerent.
  • bebimbap - Friday, September 19, 2014 - link

    there is "work" being done, as transistors have to "flip" by use of electrons. Even if you don't believe that "input energy =\= output heat" think of it this way
    100w incandescent bulb produces X amount of useful light
    18w florescent bulb also produces X amount of useful light

    in this sense the florescent bulb is much more efficient as it uses only 18w to produce the same light as the 100w incandescent. so if we say they produce the same amount of heat, then
    100w florescent would produce ~5x the light of a 100w incandescent.

    ur so smart bro
  • Guspaz - Friday, September 19, 2014 - link

    The power draw figures in this article are overall system power draw, not GPU power draw. Since the 980 offers significantly more performance than the 680, it's cranking out more frames, which causes the CPU to work harder to keep up. As as result, the CPU power draw increases, counteracting the benefits of lower GPU power draw.
  • Carrier - Friday, September 19, 2014 - link

    I don't think that can explain the whole difference. It performs similarly to a 780 Ti in Crysis 3, so the difference in power consumption can only come from the card. The 980 is rated 85W less in TDP but consumes only 68W less at the wall. The discrepancy gets worse when you add losses in the power supply.

    My guess is the TDP is rated at nominal clock rate, which is cheating a little because the card consistently runs much higher than nominal because of the boost.
