Launching Today: GTX 980 & GTX 970

Now that we’ve had a chance to take a look at the architectural and feature additions found in Maxwell 2 and GM204, let’s talk about the products themselves.

Today NVIDIA will be launching 2 products. These are the GeForce GTX 980 and GeForce GTX 970. As with past 80/70 parts this is a two tier launch, with GTX 980 being NVIDIA’s new flagship card and 1st tier GM204 card, while GTX 970 offers 2nd tier performance at much lower pricing.

Starting with the GeForce GTX 980, this is a fully enabled GM204 part. This means that 16 SMMs are enabled (2048 CUDA cores), as are all 64 ROPs and the full 256-bit memory bus. It is in other words GM204 at its best.

For clockspeeds NVIDIA is shipping GTX 980 with a base clockspeed of 1126MHz, a boost clockspeed of 1216MHz, and in our samples we have found the maximum clockspeed (highest stock boost bin) to be 1252MHz. This is a higher set of clockspeeds than any NVIDIA consumer GPU thus far, surpassing GTX 770, GTX Titan Black, and GTX 750 Ti. Curiously NVIDIA’s self-defined (and otherwise arbitrary) boost clock is much higher than on past parts; normally it would only be 50MHz or so above the base clock. This indicates that NVIDIA is getting more aggressive with their boost clock labeling and are picking values much closer to the card’s maximum clockspeed. This is a subject we will be revisiting later.

Meanwhile the memory clock stands at 7GHz, the same as with NVIDIA’s past generation of high-end cards. With GDDR5 clockspeeds all but tapped out, NVIDIA appears to have reached the limits of GDDR5 as a technology, hence their long-term interest in HBM for future architectures and improved color compression for current architectures. In any case this 7GHz of GDDR5 is attached to a 256-bit memory bus, and is populated with 4GB of VRAM. NVIDIA for the longest time has held to 2GB/3GB of memory for their cards, so it is a welcome sight to see that they are now making 4GB their standard, especially if they are going to target 4K gaming.

For power delivery GTX 980 has a rated TDP of 165W. This is significantly lower than the 250W TDPs of the GTX 780/780Ti/Titan and even the 225W TDP of the GTX 770, and heavily contributes to NVIDIA’s overall power efficiency advantage. Meanwhile NVIDIA does not specify an idle TDP, however in our testing idle power usage is lower than ever for a high-end NVIDIA card, indicating that NVIDIA should have it down to the single watt range.

Moving on, we have the GTX 980’s lower price, lower performance counterpart, the GTX 970. Compared to GTX 980, GTX 970 drops 3 of the SMMs, reducing its final count to 13 SMMs or 1664 CUDA cores. It also sheds part of a ROP/L2 cache partition while retaining the 256-bit memory bus of its bigger sibling, bringing the ROP count down to 56 ROPs and the L2 cache down to 1.75MB, a configuration option new to Maxwell.

As expected, along with the reduction in SMMs clockspeed is also reduced slightly for GTX 970. It ships at a base clockspeed of 1050MHz, with a boost clockspeed of 1178MHz. This puts the theoretical performance difference between it and the GTX 980 at about 85% of the ROP performance or about 79% of the shading/texturing/geometry performance. Given that the GTX 970 is unlikely to be ROP bound with so many ROPs, the real world performance difference should much more closely track the 79% value, meaning there is a significant performance delta between the GTX 980 and GTX 970. Elsewhere the memory configuration is unchanged from GTX 980. This means we’re looking at 4GB of GDDR5 clocked at 7GHz, all on a 256-bit bus.

GTX 970’s TDP meanwhile is lower than GTX 980’s thanks to the reduced clockspeeds and SMM count. The stock GTX 970 will be shipping with a TDP of just 145W, some 80W less than GTX 770. NVIDIA’s official designs still include 2 6-pin PCIe power sockets despite the fact that the card should technically be able to operate on just one; it is not clear at this time whether this is for overclocking purposes (150W would leave almost no power headroom) or for safety purposes since NVIDIA would be so close to going over PCIe specifications.

Due to the launch of the GTX 980 and GTX 970, NVIDIA’s product lineup will be changing to accommodate these cards. GTX 780 Ti, GTX 780, and GTX 770 are all being discontinued; their replacements offer better performance at better prices for lower power consumption. GTX 980 will be launching at $550, meanwhile GTX 970 will be launching at the surprisingly low price of $329, some 40% cheaper than GTX 980. On a historical basis GTX 980 is a bit higher than most of the past GTX x80 cards – which are often launched at $500 – while GTX 970 immediately slots in to GTX 770’s old price.

NVIDIA’s target market for the GTX 900 series will be owners of GTX 600/500/400 series cards and their AMD equivalents. GTX 980 and GTX 970 are faster than their 700 series predecessors but not immensely so, and as a result NVIDIA does not expect 700 series owners to want to upgrade so soon. Meanwhile 600 series owners and beyond are looking at 70%+ improved performance for cards at the same tier, along with some degree of a reduction in power consumption.

For today’s launch NVIDIA will be doing a reference launch of the GTX 980, so reference cards will be well represented while production of customized cards ramps up. Meanwhile GTX 970 is a pure virtual launch, meaning there will not be any reference cards at all. NVIDIA’s partners will be launching with customized designs right away, many of which will be carried over from their GTX 600/700 card designs. This will be a hard launch and cards should be readily available, and while NVIDIA should have no problem producing GM204 GPUs on the very mature TSMC 28nm process, it is difficult to predict just how well supplies will hold out.

On the competitive basis NVIDIA’s direct competition for the GTX 980 and GTX 970 will be split. GTX 980 is an immediate challenger for the Radeon R9 290X, AMD’s flagship single-GPU card which outside of a couple of sales continues to be priced around $499. GTX 970’s competition meanwhile will be split between the Radeon R9 290 and Radeon R9 280X. From a performance perspective the R9 290 is going to be the closer competitor, though it's priced around $399. Meanwhile the R9 280X will undercut the GTX 970 at around $279, but with much weaker performance.

NVIDIA for their part will not be running any promotions or bundles for the GTX 900 series, so what you see is what you get. Otherwise AMD will have their continuing Never Settle Forever bundle in play, which offers up to 3 free games in order to add value to the overall product.

Finally, there will be price cuts for the GTX 700 series. Officially GTX 760 stays in production with a new MSRP of $219. Meanwhile GTX 770, GTX 780, and GTX 780 Ti will go on clearance sale at whatever prices retailers can manage, and are still part of NVIDIA’s Borderlands bundle offer. That said, from a performance and power efficiency angle, the GTX 900 series is going to be a much more desirable product line.

    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 ? Reply

    TDP =/= Power consumption although they are related. TDP is the amount of heat it will output. Reply
  • 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.) Reply
  • 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. Reply

    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) Reply

    It's okay to be ignorant, but not ignorant and belligerent. Reply

    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.

    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. Reply
  • 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.
