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.

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.

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.

We're expecting a major announcement tomorrow... at some point. NVIDIA create a teaser website, called “Order of 10,” that is counting down to a 1PM EDT. On the same day, at 9PM EDT, they will have a live stream on their Twitch channel. This wasn't planned as long-term as their Game24 event, which turned out to be a GTX 970 and GTX 980 launch party, but it wouldn't surprise me if it ended up being a similar format. I don't know for sure whether one or both events will be about the new mainstream Pascal, but it would be surprising if Friday ends (for North America) without a GPU launch of some sort.
VideoCardz got a hold of 3DMark Fire Strike Extreme benchmarks, though. It is registered as an 8GB card with a GPU clock of 1860 MHz. While synthetic benchmarks, let alone a single benchmark of anything, isn't necessarily representative of overall performance, it scores slightly higher than a reasonably overclocked GTX 980 Ti (and way above a stock one). Specifically, this card yields a graphics score of 10102 on Fire Strike Extreme 1.1, while the 980 Ti achieved 7781 for us without an overclock.
We expected a substantial bump in clock rate, especially after GP100 was announced at GTC. This “full” Pascal chip was listed at a 1328 MHz clock, with a 1480 MHz boost. Enterprise GPUs are often underclocked compared to consumer parts, stock to stock. As stated a few times, overclocking could be a huge gap, too. The GTX 980 Ti was able to go from 1190 MHz to 1465 MHz. On the other hand, consumer Pascal's recorded 1860 MHz could itself be an overclock. We won't know until NVIDIA makes an official release. If not, maybe we could see these new parts break 2 GHz in general use?
