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.
NVIDIA's Ansel Technology
“In-game photography” is an interesting concept. Not too long ago, it was difficult to just capture the user's direct experience with a title. Print screen could only hold a single screenshot at a time, which allowed Steam and FRAPS to provide a better user experience. FRAPS also made video more accessible to the end-user, but it output huge files and, while it wasn't too expensive, it needed to be purchased online, which was a big issue ten-or-so years ago.
Seeing that their audience would enjoy video captures, NVIDIA introduced ShadowPlay a couple of years ago. The feature allowed users to, not only record video, but also capture the last few minutes. It did this with hardware acceleration, and it did this for free (for compatible GPUs). While I don't use ShadowPlay, preferring the control of OBS, it's a good example of how NVIDIA wants to support their users. They see these features as a value-add, which draw people to their hardware.

Update (May 12th, 1:45am): Okay so the post has been deleted, which was originally from Chris Bencivenga, Support Manager at EVGA. A screenshot of it is attached below. Note that Jacob Freeman later posted that "More info about SLI support will be coming soon, please stay tuned." I guess this means take the news with a grain of salt until an official word can be released.
Original Post Below
According to EVGA, NVIDIA will not support three- and four-way SLI on the GeForce GTX 1080. They state that, even if you use the old, multi-way connectors, it will still be limited to two-way. The new SLI connector (called SLI HB) will provide better performance “than 2-way SLI did in the past on previous series”. This suggests that the old SLI connectors can be used with the GTX 1080, although with less performance and only for two cards.
This is the only hard information that we have on this change, but I will elaborate a bit based on what I know about graphics APIs. Basically, SLI (and CrossFire) are simplifications of the multi-GPU load-balancing problems such that it is easy to do from within the driver, without the game's involvement. In DirectX 11 and earlier, the game cannot interface with the driver in that way at all. That does not apply to DirectX 12 and Vulkan, however. In those APIs, you will be able to explicitly load-balance by querying all graphics devices (including APUs) and split the commands yourself.
Even though a few DirectX 12 games exist, it's still unclear how SLI and CrossFire will be utilized in the context of DirectX 12 and Vulkan. DirectX 12 has the tier of multi-GPU called “implicit multi-adapter,” which allows the driver to load balance. How will this decision affect those APIs? Could inter-card bandwidth even be offloaded via SLI HB in DirectX 12 and Vulkan at all? Not sure yet (but you would think that they would at least add a Vulkan extension). You should be able to use three GTX 1080s in titles that manually load-balance to three or more mismatched GPUs, but only for those games.
If it relies upon SLI, which is everything DirectX 11, then you cannot. You definitely cannot.

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.

After the live streamed event announcing the GeForce GTX 1080 and GTX 1070, Allyn and I spent a few minutes this afternoon going over the information as it was provided, discussing our excitement about the product and coming to grips with what in the world a "Founder's Edition" even is.
If you haven't yet done so, check out Scott's summary post on the GTX 1080 and GTX 1070 specs right here.

The first non-reference GTX 1080 has been revealed courtesy of Galax, and the images (via VideoCardz.com) look a lot different than the Founder's Edition.

The Galax is the first custom implementation of the GTX 1080 we've seen, and as such the first example of a $599 variant of the GTX 1080. The Founder's Edition cards carry a $100 premium (and offer that really nice industrial design) but ultimately it's about performance and the Galax card will presumably offer completely stock specifications.

Expect to see a deluge of aftermarket cooling from EVGA, ASUS, MSI, and others soon enough - most of which will presumably be using a dual or triple-fan cooler, and not a simple blower like this.

During the GeForce GTX 1080 launch event, NVIDIA announced two prices for the card. The new GPU has an MSRP of $599 USD, while a Founders Edition will be available for $699 USD. They did not really elaborate on the difference at the keynote, but they apparently clarified the product structure for the attending press.
According to GamersNexus, the “Founders Edition” is NVIDIA's new branding for their reference design, which has been updated with the GeForce GTX 1080. That is it. Normally, a reference design is pretty much bottom-tier in a product stack. Apart from AMD's water-cooling experiments, reference designs are relatively simple, single-fan blower coolers. NVIDIA's reference cooler though, at least on their top-three-or-so models of any given generation, are pretty good. They are fairly quiet, effective, and aesthetically pleasing. When searching for a specific GPU online, you will often see a half-dozen entries based on this, from various AIB partners, and another half-dozen other offerings from those same companies, which is very different. MSI does their Twin Frozr thing, while ASUS has their Direct CU and Poseidon coolers.
If you want the $599 model, then, counter to what we've been conditioned to expect, you will not be buying NVIDIA's reference cooler. These will come from AIB partners, which means that NVIDIA is (at least somewhat) allowing them to set a minimum product this time around. They expect reference cards to be intrinsically valuable, not just purchased because they rank highest on a “sort by lowest price” metric.
This is interesting for a number of reasons. It wasn't too long ago that NVIDIA finally allowed AIB vendors to customize Titan-level graphics cards. Before that, NVIDIA's reference cooler was the only option. When they released control to their partners, we started to see water cooled Titan Xs. There is two ways to look at it: either NVIDIA is relaxing their policy of controlling user experience, or they want their personal brand to be more than the cheapest offering of their part. Granted, the GTX 1080 is supposed to be their high-end, but still mainstream offering.
It's just interesting to see this decision and rationalize it both as a release of control over user experience, and, simultaneously, as an increase of it.

So NVIDIA has announced their next generation of graphics processors, based on the Pascal architecture. They introduced it as “a new king,” because they claim that it is faster than the Titan X, even at a lower power. It will be available “around the world” on May 27th for $599 USD (MSRP). The GTX 1070 was also announced, with slightly reduced specifications, and it will be available on June 10th for $379 USD (MSRP).
Pascal is created on the 16nm process at TSMC, which gives them a lot of headroom. They have fewer shaders than the Titan X, but with a significantly higher clock rate. It also uses GDDR5X, which is an incremental improvement over GDDR5. We knew it wasn't going to use HBM2.0, like Big Pascal does, but it's interesting that they did not stick with old, reliable GDDR5.
The full specifications of the GTX 1080 are as follows:
- 2560 CUDA Cores
- 1607 MHz Base Clock (8.2 TFLOPs)
- 1733 MHz Boost Clock (8.9 TFLOPs)
- 8GB GDDR5X Memory at 320 GB/s (256-bit)
- 180W Listed Power (Update: uses 1x 8-pin power)
We do not currently have the specifications of the GTX 1070, apart from it being 6.5 TFLOPs.
It also looks like it has five display outputs: 3x DisplayPort 1.2, which are “ready” for 1.3 and 1.4, 1x HDMI 2.0b, and 1x DL-DVI. They do not explicitly state that all three DisplayPorts will run on the same standard, even though that seems likely. They also do not state whether all five outputs can be used simultaneously, but I hope that they can be.
They also have a new SLI bridge, called SLI HB Bridge, that is supposed to have double the bandwidth of Maxwell. I'm not sure what that will mean for multi-gpu systems, but it will probably be something we'll find out about soon.
