GP106 Preview

It’s probably not going to come as a surprise to anyone that reads the internet, but NVIDIA is officially taking the covers off its latest GeForce card in the Pascal family today, the GeForce GTX 1060. As the number scheme would suggest, this is a more budget-friendly version of NVIDIA’s latest architecture, lowering performance in line with expectations. The GP106-based GPU will still offer impressive specifications and capabilities and will probably push AMD’s new Radeon RX 480 to its limits.

The GeForce GTX 1060 will sport 1280 CUDA cores with a GPU Boost clock speed rated at 1.7 GHz. Though the card will be available in only 6GB varieties, the reference / Founders Edition will ship with 6GB of GDDR5 memory running at 8.0 GHz / 8 Gbps. With 1280 CUDA cores, the GP106 GPU is essentially one half of a GP104 in terms of compute capability. NVIDIA decided not to cut the memory interface in half though, instead going with a 192-bit design compared to the GP104 and its 256-bit option.

The rated GPU clock speeds paint an interesting picture for peak performance of the new card. At the rated boost clock speed, the GeForce GTX 1070 produces 6.46 TFLOPS of performance. The GTX 1060 by comparison will hit 4.35 TFLOPS, a 48% difference. The GTX 1080 offers nearly the same delta of performance above the GTX 1070; clearly NVIDIA has set the scale Pascal and product deviation.

NVIDIA wants us to compare the new GeForce GTX 1060 to the GeForce GTX 980 in gaming performance, but the peak theoretical performance results don’t really match up. The GeForce GTX 980 is rated at 4.61 TFLOPS at BASE clock speed, while the GTX 1060 doesn’t hit that number at its Boost clock. Obviously Pascal improves on performance with memory compression advancements, but the 192-bit memory bus is only able to run at 192 GB/s, compared to the 224 GB/s of the GTX 980. Obviously we’ll have to wait for performance result from our own testing to be sure, but it seems possible that NVIDIA’s performance claims might depend on technology like Simultaneous Multi-Projection and VR gaming to be validated.

NVIDIA Announces GeForce Experience 3.0 Beta

Tagged: nvidia, geforce, geforce experience

GeForce Experience will be getting an updated UI soon, and a beta release is available now. It has basically been fully redesigned, although the NVIDIA Control Panel is the same as it has been. That said, even though it is newer, GeForce Experience could benefit from a good overhaul, especially in terms of start-up delay. NVIDIA says it uses 2X less memory and loads 3X faster. It still has a slightly loading bar, but less than a second.

nvidia-2016-gfe3-01.png

Interestingly, I noticed that, even though I skipped over Sharing Settings on first launch, Instant Replay was set to On by default. This could have been carried over from my previous instance of GeForce Experience, although I'm pretty sure I left it off. Privacy-conscious folks might want to verify that ShadowPlay isn't running, just in case.

nvidia-2016-gfe3-02.png

One downside for some of our users is that you now require an NVIDIA account (or connect your Google Account to NVIDIA) to access it. Previously, you could use features, like ShadowPlay, while logged out, but that doesn't appear to be the case anymore. This will no-doubt upset some of our audience, but it's not entirely unexpected, given NVIDIA's previous statements about requiring an NVIDIA account for Beta drivers. The rest of GeForce Experience isn't too surprising considering that.

nvidia-2016-gfe3-03.png

We'll now end where we began: installation. For testing (and hopefully providing feedback) during the beta, NVIDIA will be giving away GTX 1080s on a weekly basis. To enter, you apparently just need to install the Beta and log in with your NVIDIA (or Google) account.

You have already seen our delve into the frame times provided by the GTX 1080 but perhaps you would like another opinion.  The Tech Report also uses the FCAT process which we depend upon to bring you frame time data, however they present the data in a slightly different way which might help you to comprehend the data.  They also included Crysis 3 to ensure that the card can indeed play it.  Check out their full review here.

GeForce GTX 1080 and 1070 3-Way and 4-Way SLI will not be enabled for games

Subject: Graphics Cards | June 8, 2016 - 08:44 PM |
Tagged: sli, pascal, nvidia, GTX 1080, GP104, geforce, 4-way sli, 3-way sli

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.

01.jpg

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.

driver2.jpg

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. 

driver1.jpg

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." 

03.jpg

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.

lux2.jpg

I did so, and the result is an impressive score of 17,127!!

lux.jpg

How does that compare to some other products?

luxmarkgraph.jpg

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!

02.jpg

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.

The frequency of Pascal reviews is still increasing

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.

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.

nvidia1.jpg

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.

Manufacturer: NVIDIA

First, Some Background

 
TL;DR:
NVIDIA's Rumored GP102
 
Based on two rumors, NVIDIA seems to be planning a new GPU, called GP102, that sits between GP100 and GP104. This changes how their product stack flowed since Fermi and Kepler. GP102's performance, both single-precision and double-precision, will likely signal NVIDIA's product plans going forward.
  • - GP100's ideal 1 : 2 : 4 FP64 : FP32 : FP16 ratio is inefficient for gaming
  • - GP102 either extends GP104's gaming lead or bridges GP104 and GP100
  • - If GP102 is a bigger GP104, the future is unclear for smaller GPGPU devs
    • This is, unless GP100 can be significantly up-clocked for gaming.
  • - If GP102 matches (or outperforms) GP100 in gaming, and has better than 1 : 32 double-precision performance, then GP100 would be the first time that NVIDIA designed an enterprise-only, high-end GPU.
 

 

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.

nvidia-titan-black-1.jpg

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.

Fast-forward to Pascal.
