IMPORTANT UPDATE: After writing this story, but before publication, we went to NVIDIA for comment. As we were getting ready to publish, the company updated me with a shift in its stance on multi-GPU configurations. NVIDIA will no longer require an "enthusiast key" to enable SLI on more than two GPUs. However, NVIDIA will also only be enabling 3-Way and 4-Way SLI for a select few applications. More details are at the bottom of the story!
You'll likely recall that during our initial review of the GeForce GTX 1080 Founders Edition graphics card, we mentioned that NVIDIA was going to be moving people towards the idea that "only 2-Way SLI will be supported" and promoted. There would still be a path for users that wanted 3 and 4 GPU configurations anyway, and it would be called the Enthusiast Key.
As it turns out, after returning from an AMD event focused on its upcoming Polaris GPUs, I happen to have amassed a total of four GeForce GTX 1080 cards.
Courtesy of some friends at EVGA and two readers that were awesome enough to let me open up their brand new hardware for a day or so, I was able to go through the 3-Way and 4-Way SLI configuration process. Once all four were installed, and I must point out how great it is that each card only required a single 8-pin power connector, I installed the latest NVIDIA driver I had on hand, 368.19.
Knowing about the need for the Enthusiast Key, and also knowing that I did not yet have one and that the website that was supposed to be live to enable me to get one is still not live, I thought I might have stumbled upon some magic. The driver appeared to let me enable SLI anyway.
Enthusiasts will note however that the green marker under the four GPUs with the "SLI" text is clearly only pointing at two of the GTX 1080s, leaving the remaining two...unused. Crap.
At this point, if you have purchased more than two GeForce GTX 1080 cards are simply out of luck and are waiting on NVIDIA to make good on it's promise to allow for 3-Way and 4-Way configurations via the Enthusiast Key. Or some other way. It's way too late now to simply say "we aren't supporting it at all."
While I wait...what is there for a gamer with four GeForce GTX 1080 cards to do? Well, you could run Ashes of the Singularity. It's multi-GPU mode uses MDA mode, which means the game engine itself accesses each GPU on its own, without the need for the driver to handle anything regarding GPU load balancing. Unfortunately, Ashes only supports two GPUs today.
Well...you could run an OpenCL based benchmark like LuxMark that access all the GPUs independently as well.
I did so, and the result is an impressive score of 17,127!!
How does that compare to some other products?
The four GTX 1080 cards produce a score that is 2.57x the result provided by the AMD Radeon Pro Duo and 2.29x the score of SLI GeForce GTX 980 Ti cards. Nice!
So there you go! We are just as eager to get our hands on the ability to test 3-Way and 4-Way SLI with new Pascal GPUs as some of the most extreme and dedicated enthusiasts out there are. With any luck, NVIDIA will finally figure out a way to allow it - no matter how it finally takes place.
IMPORTANT UPDATE: Before going to press with this story I asked NVIDIA for comment directly: when was the community finally going to get the Enthusiast Key website to unlock 3-Way and 4-Way SLI for those people crazy enough to have purchased that many GTX 1080s? The answer was quite surprising: NVIDIA is backing away from the idea of an "Enthusiast Key" and will no longer require it for enabling 3-Way and 4-Way SLI.
Here is the official NVIDIA statement given to PC Perspective on the subject:
With the GeForce 10-series we’re investing heavily in 2-way SLI with our new High Bandwidth bridge (which doubles the SLI bandwidth for faster, smoother gaming at ultra-high resolutions and refresh rates) and NVIDIA Game Ready Driver SLI profiles. To ensure the best possible gaming experience on our GeForce 10-series GPUs, we’re focusing our efforts on 2-way SLI only and will continue to include 2-way SLI profiles in our Game Ready Drivers.
DX12 and NVIDIA VR Works SLI technology also allows developers to directly implement and control multi-GPU support within their games. If a developer chooses to use these technologies then their game will not need SLI profiles. Some developers may also decide to support more than 2 GPUs in their games. We continue to work with all developers creating games and VR applications that take advantage of 2 or more GPUs to make sure they’ll work great on GeForce 10-series GPUs.
For our overclocking community, our Game Ready Drivers will also include SLI profiles for 3- and 4-way configurations for specific OC applications only, including Fire Strike, Unigine and Catzilla.
NVIDIA clearly wants to reiterate that only 2-Way SLI will get the attention that we have come to expect from the GeForce driver dev team. As DX12 and Vulkan next-generation APIs become more prolific, the game developers will still have the ability to directly access more than two GeForce GTX 10-series GPUs, though I expect that be a very narrow window of games simply due to development costs and time.
NVIDIA will enable support for three and four card configurations in future drivers (without a key) for specific overclocking/benchmarking tools only, as a way to make sure the GeForce brand doesn't fall off the 3DMark charts. Only those specific applications will be able operate in the 3-Way and 4-Way SLI configurations that you have come to know. There are no profiles to change manually and even the rare games that might have "just worked" with three or four GPUs will not take advantage of more than two GTX 10-series cards. It's fair to say at this point that except for the benchmarking crowd, NVIDIA 3-Way and 4-Way SLI is over.
We expect the "benchmark only" mode of 3-Way and 4-Way SLI to be ready for consumers with the next "Game Ready" driver release. If you happened to get your hands on more than two GTX 1080s but aren't into benchmarking, then find those receipts and send a couple back.
So there you have it. Honestly, this is what I was expecting from NVIDIA with the initial launch of Pascal and the GeForce GTX 1080/1070 and I was surprised when I first heard about the idea of the "enthusiast key." It took a bit longer than expected, and NVIDIA will get more flak for the iterated dismissal of this very niche, but still pretty cool, technology. In the end, this won't have much impact on the company's bottom line as the quantity of users that were buying 3+ GTX GPUs for a single system was understandably small.

With Computex behind us it is time to catch up on all the reviews which were launched during the show, including [H]ard|OCP's review of the GTX 1070 Founders Edition. Their testing was done using an NVIDIA provided driver, GeForce 368.19 the same one which Ryan used in his review. They did not have a chance to delve into overclocking or utilizing the new power settings. From their testing they concluded the GTX 1070 is a great upgrade for those using a vanilla GTX 980 or R9 390X, while the card performs faster than a R9 Fury X or GTX 980 Ti the jump is not quite enough to recommend dumping it for anything less than a GTX1080.
"In our review of the NVIDIA GeForce GTX 1070 Founders Edition video card we will explore the price competitive performance and find out what kind of gameplay advantage the new GeForce GTX 1070 Founders Edition offers over the previous generation cards. We compare both the GTX 980 and Radeon R9 Fury GPUs to the new GTX 1070"

If we missed your favourite game, synthetic benchmark or a specific competitors card in our review of the new GTX 1070 then perhaps one of the sites below might satisfy your cravings. For instance, if it is Ashes of the Singularity or The Division which you want to see benchmarked the [H]ard|OCP has you covered. They also had a go at overclocking, with the new software they tweaked the card's fan speed to 100%, power target at 112%, and GPU Offset overclocking at +230. That resulted in a peak GPU speed of 2113MHz although the averaged frequency over a 30 minute gaming session was 2052MHz, they will revisit the card to overclock the memory in the near future. Check out their full review here.
"The second video card in the NVIDIA next generation Pascal GPU architecture is finally here, we will explore the GeForce GTX 1070 Founders Edition video card. In this limited preview today we will look at performance in comparison to GeForce GTX 980 Ti and Radeon R9 Fury X as well as some preview overclocking."

GP104 Strikes Again
It’s only been three weeks since NVIDIA unveiled the GeForce GTX 1080 and GTX 1070 graphics cards at a live streaming event in Austin, TX. But it feels like those two GPUs, one of which hasn't even been reviewed until today, have already drastically shifted the landscape of graphics, VR and PC gaming.
Half of the “new GPU” stories are told, with AMD due to follow up soon with Polaris, but it was clear to anyone watching the enthusiast segment with a hint of history that a line was drawn in the sand that day. There is THEN, and there is NOW. Today’s detailed review of the GeForce GTX 1070 completes NVIDIA’s first wave of NOW products, following closely behind the GeForce GTX 1080.
Interestingly, and in a move that is very uncharacteristic of NVIDIA, detailed specifications of the GeForce GTX 1070 were released on GeForce.com well before today’s reviews. With information on the CUDA core count, clock speeds, and memory bandwidth it was possible to get a solid sense of where the GTX 1070 performed; and I imagine that many of you already did the napkin math to figure that out. There is no more guessing though - reviews and testing are all done, and I think you'll find that the GTX 1070 is as exciting, if not more so, than the GTX 1080 due to the performance and pricing combination that it provides.
Let’s dive in.
First, Some Background
NVIDIA's Rumored GP102
When GP100 was announced, Josh and I were discussing, internally, how it would make sense in the gaming industry. Recently, an article on WCCFTech cited anonymous sources, which should always be taken with a dash of salt, that claimed NVIDIA was planning a second architecture, GP102, between GP104 and GP100. As I was writing this editorial about it, relating it to our own speculation about the physics of Pascal, VideoCardz claims to have been contacted by the developers of AIDA64, seemingly on-the-record, also citing a GP102 design.
I will retell chunks of the rumor, but also add my opinion to it.
In the last few generations, each architecture had a flagship chip that was released in both gaming and professional SKUs. Neither audience had access to a chip that was larger than the other's largest of that generation. Clock rates and disabled portions varied by specific product, with gaming usually getting the more aggressive performance for slightly better benchmarks. Fermi had GF100/GF110, Kepler had GK110/GK210, and Maxwell had GM200. Each of these were available in Tesla, Quadro, and GeForce cards, especially Titans.
Maxwell was interesting, though. NVIDIA was unable to leave 28nm, which Kepler launched on, so they created a second architecture at that node. To increase performance without having access to more feature density, you need to make your designs bigger, more optimized, or more simple. GM200 was giant and optimized, but, to get the performance levels it achieved, also needed to be more simple. Something needed to go, and double-precision (FP64) performance was the big omission. NVIDIA was upfront about it at the Titan X launch, and told their GPU compute customers to keep purchasing Kepler if they valued FP64.

Yes that's right, if you felt Ryan and Al somehow missed something in our review of the new GTX 1080 or you felt the obvious pro-Matrox bios was showing here are the other reviews you can pick and choose from. Start off with [H]ard|OCP who also tested Ashes of the Singularity and Doom as well as the old favourite Battlefield 4. Doom really showed itself off as a next generation game, its Nightmare mode scoffing at any GPU with less than 5GB of VRAM available and pushing the single 1080 hard. Read on to see how the competition stacked up ... or wait for the 1440 to come out some time in the future.
"NVIDIA's next generation video card is here, the GeForce GTX 1080 Founders Edition video card based on the new Pascal architecture will be explored. We will compare it against the GeForce GTX 980 Ti and Radeon R9 Fury X in many games to find out what it is capable of."

The summer of change for GPUs has begun with today’s review of the GeForce GTX 1080. NVIDIA has endured leaks, speculation and criticism for months now, with enthusiasts calling out NVIDIA for not including HBM technology or for not having asynchronous compute capability. Last week NVIDIA’s CEO Jen-Hsun Huang went on stage and officially announced the GTX 1080 and GTX 1070 graphics cards with a healthy amount of information about their supposed performance and price points. Issues around cost and what exactly a Founders Edition is aside, the event was well received and clearly showed a performance and efficiency improvement that we were not expecting.
The question is, does the actual product live up to the hype? Can NVIDIA overcome some users’ negative view of the Founders Edition to create a product message that will get the wide range of PC gamers looking for an upgrade path an option they’ll take?
I’ll let you know through the course of this review, but what I can tell you definitively is that the GeForce GTX 1080 clearly sits alone at the top of the GPU world.

The GTX 1080 announcement is starting to ripple into retailers, leading to price cuts on the previous generation, Maxwell-based SKUs. If you were interested in the GTX 1080, or an AMD graphics card of course, then you probably want to keep waiting. That said, you can take advantage of the discounts to get a VR-ready GPU or if you already have a Maxwell card that could use a cheap SLI buddy.
This tip comes from a NeoGAF thread. Microcenter has several cards on sale, but EVGA seems to have the biggest price cuts. This 980 Ti has dropped from $750 USD down to $499.99 (or $474.99 if you'll promise yourself to do that mail-in rebate). That's a whole third of its price slashed, and puts it about a hundred dollars under GTX 1080. Granted, it will also be slower than the GTX 1080, with 2GB less video RAM, but $100 might be worth that for you.
