The NVIDIA GeForce GTX 970 Review: Featuring EVGAby Ryan Smith on September 26, 2014 10:00 AM EST
Last week we took a look at NVIDIA’s newest consumer flagship video card, the GeForce GTX 980. Based on the company’s new GM204 GPU, GTX 980 further cemented NVIDIA’s ownership of the performance crown with a combination of performance improvements, new features, and power consumption reductions. Combined with a lower price than the now-dethroned GTX 780 Ti, GTX 980 is an impressive flagship with a mix of attributes that NVIDIA hopes to entice existing 600 and 500 series owners to upgrade to.
Of course even though GTX 980 was cheaper than the outgoing GTX 780 Ti, it is still a flagship card and at $549 is priced accordingly. But as in every GeForce product lineup there is a GeForce x70 right behind it, and for GTX 980 its lower-tier, lower priced counterpart is the GeForce GTX 970. Based on the same GM204 but configured with fewer active SMMs, a slightly lower clock speed, and a lower TDP, GTX 970 fills the gap by providing a lower performance but much lower priced alternative to the flagship GTX 980. In fact at $329 it’s some 40% cheaper than GTX 980, one of the largest discounts for a second-tier GeForce card in recent memory.
For this reason GTX 970 is an interesting card on its own, if not more interesting overall than its bigger sibling. The performance decrease from the reduced clock speeds and fewer SMMs is going to be tangible, but then so is a $220 savings to the pocketbook. With GTX 980 already topping our charts, if GTX 970 can stay relatively close then it would be a very tantalizing value proposition for enthusiast gamers who want to buy in to GM204 at a lower price.
|NVIDIA GPU Specification Comparison|
|GTX 980||GTX 970 (CorrecteD)||GTX 780||GTX 770|
|Memory Clock||7GHz GDDR5||7GHz GDDR5||6GHz GDDR5||7GHz GDDR5|
|Memory Bus Width||256-bit||256-bit||384-bit||256-bit|
|FP64||1/32 FP32||1/32 FP32||1/24 FP32||1/24 FP32|
|Manufacturing Process||TSMC 28nm||TSMC 28nm||TSMC 28nm||TSMC 28nm|
Compared to GTX 980 and its full-fledged GM204 GPU, GTX 970 takes a harvested GM204 that 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
Along with the reduction in SMMs clock speed is also reduced slightly for GTX 970. It ships at a base clock speed of 1050MHz and a boost clock speed 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 still potentially 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. Compared to the GTX 770 that the GTX 970 replaces, this is a welcome and much needed upgrade from what has been the 2GB VRAM standard that NVIDIA has held to for the last two and a half years.
GTX 970’s TDP meanwhile is lower than GTX 980’s thanks to the reduced clock speeds and SMM count. The stock GTX 970 will be shipping with a TDP of just 145W, some 80W less than GTX 770’s official TDP of 225W. 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.
Like the GTX 980, NVIDIA’s target market for the GTX 970 will be owners of GTX 600/500/400 series cards and their AMD equivalents. GTX 970 is faster than GTX 770 but not immensely so, and as a result NVIDIA does not expect GTX 770 owners to want to upgrade so soon. Meanwhile GTX 670 owners and beyond are looking at 65%+ improved performance for cards at the same tier, while power consumption will remain roughly consistent from the GTX 670’s 140W GPU Boost 1.0-based power target.
Furthermore, as we mentioned in our GTX 980 review, GTX 970 has been a pure virtual (no reference card) launch, which means all of NVIDIA’s partners are launching their custom cards right out of the gate. A lot of these have been recycled or otherwise only slightly modified GTX 700/600 series designs, owing to the fact that GM204’s memory bus has been held at 256-bits and its power requirements are so low.
Meanwhile since NVIDIA did not produce reference cards, for GTX 970 reviewers are being sampled directly by NVIDIA’s partners. For our review today we will be looking at EVGA’s GeForce GTX 970 FTW ACX 2.0, the company’s highest performance GTX 970 card. Accordingly, we will be taking a look at both it’s out of the box performance and performance when reconfigured as a stock card to showcase both performance profiles.
With the discontinuation of the GTX 780 series and GTX 770, competition for the GTX 970 will be split between the GTX 760 and GTX 980 on the NVIDIA side. On the AMD side things will be even more spread out; AMD’s closest cards from a pricing perspective are the R9 280X and R9 290 priced below and above the $329 GTX 970 respectively, but as we’ll see even R9 290X is not necessarily out of the picture thanks to GM204’s strong performance.
Surprisingly even a week after the launch of the GTX 900 series, AMD has yet to officially respond to the GTX 900 series launch with any further price cuts or additional incentives beyond their existing Never Settle Forever bundle. In lieu of that some retailers have been running their own promotions; our pricing benchmark retailer Newegg has been offering 15% discounts on some of their PowerColor R9 290 series cards, meanwhile some other cards qualify for a $40 Newegg gift card (which cannot be applied retroactively to the purchase). Since the bulk of these cards don’t qualify for the price discount we’re holding our reference prices at $500 for the R9 290X and $400 for the R9 290, however the very cheapest of these PowerColor cards with the discount in play can go for as little as $450 and $340 respectively.
Meanwhile GTX 900 series sales have been brisk, and while the cards are still in supply not all models are available or are regularly available. At the very least everything from reference clocked cards to significantly overclocked cards are available at Newegg, so there is still a range of options. Though they are coincidentally all EVGA cards as of publication time.

MrSpadge - Saturday, September 27, 2014 - linkWhat you describe is what Tonga should have been. Didn't turn out so well :/
Sure, the 285 is priced below GM204 cards, but the chip is almost as large and hence costs AMD the same to produce it. They SHOULD play in the same league.
thepaleobiker - Friday, September 26, 2014 - link"Crysis 3 Summary" - The GTX 670 trails the R9 290XU by 10%....
It should be the GTX 970 :)
Also, on the page with Company of Heroes - The Charts do not display correctly, or more specifically, their headers (the thick Blue bar/heading with info about resolution etc?) are cropped out on all the images except the first one.
krazyfrog - Friday, September 26, 2014 - linkAlso, last page, fifth paragraph
"AMD would have to cut R9 290X’s performance by nearly $200 to be performance competitive, and even then they can’t come close to matching NVIDIA’s big edge in power consumption."
Should be '290X's price', I believe.
CZroe - Friday, September 26, 2014 - linkI have the reference style 4GB EVGA GTX 760 with the short PCB but it was discontinued shortly after launch. I got some 670/760 water blocks for SLI from Swiftech and found that only Zotac was making a short PCB 4GB GTX 760 card like my EVGA even though it has fewer memory chips (probably worse for over locking). Because the vast majority of GTX 760 cards had reference 680 PCBs, it is very difficult to tell which "reference" 760 this article is talking about. The rare short PCB or the longer one?
Ryan Smith - Friday, September 26, 2014 - linkThe short PCB and the stretched PCB were virtually identical, so to answer the question I'm technically comparing it to the short PCB, but either comparison is valid. The stretched section only contains a handful of additional discrete components; it's mostly to allow fitting an open air cooler.
Atari2600 - Friday, September 26, 2014 - linkThe Radeon 290x is nearly a year old now. It would be surprising if an Nvidia GPU that sacrifices DP capability wouldn't be significantly quicker per mm^2 at this point.
The improvement in performance/watt is notable and nvidia deserve much credit for their work in this area.
Phasenoise - Friday, September 26, 2014 - linkOh my the name of that card. "EVGA GeForce GTX 970 FTW ACX 2.0"
Reads like my niece's texting log. omg lol gtx ftw, btb.
jjj - Friday, September 26, 2014 - link"considering the fact that GTX 970 is a $329 card I don’t seriously expect it to be used for 4K gaming"
You should and Nvidia should market it as lowering the entry price for 4k. It's kinda the least you need for 4k, can do 4k just not max setting everywhere for just 329$. Pair it with some bellow 500$ screen deal and 4k gaming is a lot more accessible than 2 weeks ago.
We've looked at what's the bare minimum for 1080p for years and we are used to it, now it's 4k's turn to become more mainstream and we need to get used to looking at it the same way.
in the US and even more so in China 4k screens are not that prohibitive anymore. 400-500$ for a screen, 330$ for a 970, an overclocked dual core and you can do budget 4k gaming at 1.2k$.
4k should be one of the reasons some people that buy 200$ cards might go for the 970 this time around.
And with 20nm 4k should become a lot more affordable so it's time to not think of it as a small niche.
garadante - Friday, September 26, 2014 - linkCan we get power usage with non reference 290/290X's? If I recall correctly, power usage drops something like 15-25 watts when it's running at closer to 70 C than 95 C as reference cooling profiles make it run.
justaviking - Friday, September 26, 2014 - linkZero Fan Speed Idling...
Will the zero fan speed capability be something that will be delivered via a driver update? I hope so. Or will it require a "Rev B" of the hardware too?
I don't need silence, but quiet is nice. I assumed the 970 would be quite a bit quieter than the 980 due to lower TDP. The test results surprise me (not in a good way).
This makes me even more impressed with the 980. But it still costs $200 more. Tough choice.
