What Are NVIDIA GeForce GTX 1080 Founders Edition Cards?

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.

nvidia-2016-dreamhack-1080-specs.png

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.

AMD Releases Radeon Software Crimson Edition 16.5.1 Beta

Subject: Graphics Cards | May 9, 2016 - 02:05 PM |
Tagged: amd, graphics drivers, crimson

This is good to see. AMD has released Radeon Software Crimson Edition 16.5.1 to align with Forza Motorsport 6: Apex. The drivers are classified as Beta, and so is the game, coincidentally, which means 16.5.1 is not WHQL-certified. That doesn't have the weight that it used to, though. Its only listed feature is performance improvements with that title, especially for the R9 Fury X graphics card. Game-specific optimizations near launch appear to be getting consistent, and that was an area that AMD really needed to improve upon, historically.

amd-2015-crimson-logo.png

There are a handful of known issues, but they don't seem particularly concerning. The AMD Gaming Evolved overlay may crash in some titles, and The Witcher 3 may flicker in Crossfire, both of which could be annoying if they affect a game that you have been focusing on, but that's about it. There might be other issues (and improvements) that are not listed in the notes, but that's all I have to work on at the moment.

NVIDIA GeForce GTX 1080 and GTX 1070 Announced

Subject: Graphics Cards | May 6, 2016 - 10:38 PM |
Tagged: pascal, nvidia, GTX 1080, gtx 1070, GP104, geforce

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.

nvidia-2016-dreamhack-1080-specs.png

nvidia-2016-dreamhack-1070-specs.png

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.

nvidia-2016-dreamhack-1080-stockphoto.png

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.

nvidia-2016-dreamhack-newsli.png

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.

NVIDIA GeForce "GTX 1080" Benchmark Leaked

Subject: Graphics Cards | May 5, 2016 - 02:38 PM |
Tagged: nvidia, pascal, geforce

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?

This is your AMD APU. This is your AMD APU on DX12; any questions?

Earlier in the month [H]ard|OCP investigated the performance scaling that Intel processors display in DX12, now they have finished their tests on AMD processors.  These tests include Async computing information, so be warned before venturing forth into the comments.  [H] tested an FX 8370 at 2GHz and 4.3GHz to see what effect this had on the games, the 3GHz tests did not add any value and were dropped in favour of these two turbo frequencies.  There are some rather interesting results and discussion, drop by for the details.

"One thing that has been on our minds about the new DX12 API is its ability to distribute workloads better on the CPU side. Now that we finally have a couple of new DX12 games that have been released to test, we spend a bit of time getting to bottom of what DX12 might be able to do for you. And a couple sentences on Async Compute."

History and Specifications

The Radeon Pro Duo had an interesting history. Originally shown as an unbranded, dual-GPU PCB during E3 2015, which took place last June, AMD touted it as the ultimate graphics card for both gamers and professionals. At that time, the company thought that an October launch was feasible, but that clearly didn’t work out. When pressed for information in the Oct/Nov timeframe, AMD said that they had delayed the product into Q2 2016 to better correlate with the launch of the VR systems from Oculus and HTC/Valve.

During a GDC press event in March, AMD finally unveiled the Radeon Pro Duo brand, but they were also walking back on the idea of the dual-Fiji beast being aimed at the gaming crowd, even partially. Instead, the company talked up the benefits for game developers and content creators, such as its 8192 stream processors for offline rendering, or even to aid game devs in the implementation and improvement of multi-GPU for upcoming games.

Anyone that pays attention to the graphics card market can see why AMD would make the positional shift with the Radeon Pro Duo. The Fiji architecture is on the way out, with Polaris due out in June by AMD’s own proclamation. At $1500, the Radeon Pro Duo will be a stark contrast to the prices of the Polaris GPUs this summer, and it is well above any NVIDIA-priced part in the GeForce line. And, though CrossFire has made drastic improvements over the last several years thanks to new testing techniques, the ecosystem for multi-GPU is going through a major shift with both DX12 and VR bearing down on it.

So yes, the Radeon Pro Duo has both RADEON and PRO right there in the name. What’s a respectable PC Perspective graphics reviewer supposed to do with a card like that if it finds its way into your office? Test it of course! I’ll take a look at a handful of recent games as well as a new feature that AMD has integrated with 3DS Max called FireRender to showcase some of the professional chops of the new card.

Tagged: graphics driver, crimson, amd

AMD's new Crimson driver has just been released with new features including official support for the new Radeon Pro Duo as well as both the Oculus Rift and HTC Vive VR headsets.  It also adds enhanced support for AMD's XConnect technology for external GPUs connected via a Thunderbolt 3 interface.  Crossfire profile updates include Hitman, Elite Dangerous and Need for Speed and they have also resolved the ongoing issue with the internal update procedure not seeing the newest drivers.  If you are having issues with games crashing to desktop on launch you will still need to disable the AMD Gaming Evolved overlay, unfortunately.

Get 'em right here!

"The latest version of Radeon Software Crimson Edition is here with 16.4.2. With this version, AMD delivers many quality improvements, updated/introduced new CrossFire profiles and delivered full support for AMD’s XConnect technology (including plug’n’play simplicity for Thunderbolt 3 eGFX enclosures configured with Radeon R9 Fury, Nano or 300 Series GPUs.)  Best of all, our DirectX 12 leadership continues to be strong, as shown by the performance numbers below."

The Dual-Fiji Card Finally Arrives

This weekend, leaks of information on both WCCFTech and VideoCardz.com have revealed all the information about the pending release of AMD’s dual-GPU giant, the Radeon Pro Duo. While no one at PC Perspective has been briefed on the product officially, all of the interesting data surrounding the product is clearly outlined in the slides on those websites, minus some independent benchmark testing that we are hoping to get to next week. Based on the report from both sites, the Radeon Pro Duo will be released on April 26th.

AMD actually revealed the product and branding for the Radeon Pro Duo back in March, during its live streamed Capsaicin event surrounding GDC. At that point we were given the following information:

  • Dual Fiji XT GPUs
  • 8GB of total HBM memory
  • 4x DisplayPort (this has since been modified)
  • 16 TFLOPS of compute
  • $1499 price tag

The design of the card follows the same industrial design as the reference designs of the Radeon Fury X, and integrates a dual-pump cooler and external fan/radiator to keep both GPUs running cool.

Based on the slides leaked out today, AMD has revised the Radeon Pro Duo design to include a set of three DisplayPort connections and one HDMI port. This was a necessary change as the Oculus Rift requires an HDMI port to work; only the HTC Vive has built in support for a DisplayPort connection and even in that case you would need a full-size to mini-DisplayPort cable.

The 8GB of HBM (high bandwidth memory) on the card is split between the two Fiji XT GPUs on the card, just like other multi-GPU options on the market. The 350 watts power draw mark is exceptionally high, exceeded only by AMD’s previous dual-GPU beast, the Radeon 295X2 that used 500+ watts and the NVIDIA GeForce GTX Titan Z that draws 375 watts!

02-official.jpg

Here is the specification breakdown of the Radeon Pro Duo. The card has 8192 total stream processors and 128 Compute Units, split evenly between the two GPUs. You are getting two full Fiji XT GPUs in this card, an impressive feat made possible in part by the use of High Bandwidth Memory and its smaller physical footprint.

The Radeon Pro Duo has a rated clock speed of up to 1000 MHz. That’s the same clock speed as the R9 Fury and the rated “up to” frequency on the R9 Nano. It’s worth noting that we did see a handful of instances where the R9 Nano’s power limiting capability resulted in some extremely variable clock speeds in practice. AMD recently added a feature to its Crimson driver to disable power metering on the Nano, at the expense of more power draw, and I would assume the same option would work for the Pro Duo.

Report: NVIDIA GP104 Die Pictured; GTX 1080 Does Not Use HBM

Subject: Graphics Cards | April 22, 2016 - 10:16 AM |
Tagged: rumor, report, pascal, nvidia, leak, graphics card, gpu, gddr5x, GDDR5

According to a report from VideoCardz (via Overclock.net/Chip Hell) high quality images have leaked of the upcoming GP104 die, which is expected to power the GeForce GTX 1070 graphics card.

NVIDIA-GP104-GPU.jpg

"This GP104-200 variant is supposedly planned for GeForce GTX 1070. Although it is a cut-down version of GP104-400, both GPUs will look exactly the same. The only difference being modified GPU configuration. The high quality picture is perfect material for comparison."

A couple of interesting things have emerged with this die shot, with the relatively small size of the GPU (die size estimated at 333 mm2), and the assumption that this will be using conventional GDDR5 memory - based on a previously leaked photo of the die on PCB.

"Leaker also says that GTX 1080 will feature GDDR5X memory, while GTX 1070 will stick to GDDR5 standard, both using 256-bit memory bus. Cards based on GP104 GPU are to be equipped with three DisplayPorts, HDMI and DVI."

While this is no doubt disappointing to those anticipating HBM with the upcoming Pascal consumer GPUs, the move isn't all that surprising considering the consistent rumors that GTX 1080 would use GDDR5X.

Is the lack of HBM (or HBM2) enough to make you skip this generation of GeForce GPU? This author points out that AMD's Fury X - the first GPU to use HBM - was still unable to beat a GTX 980 Ti in many tests, even though the 980 Ti uses conventional GDDR5. Memory is obviously important, but the core defines the performance of the GPU.

If NVIDIA has made improvements to performance and efficiency we should see impressive numbers, but this might be a more iterative update than originally expected - which only gives AMD more of a chance to win marketshare with their upcoming Radeon 400-series GPUs. It should be an interesting summer.
