NVIDIA is working on a fix to allow the HTC Vive to be connected to the GeForce GTX 1070 and GTX 1080 over DisplayPort. The HTC Vive apparently has the choice between HDMI and Mini DisplayPort, but the headset will not be identified when connected over that connection. Currently, the two workarounds are to connect the HTC Vive over HDMI, or use a DisplayPort to HDMI adapter if your card's HDMI output is already occupied.
It has apparently been an open issue for over a month now. That said, NVIDIA's Manuel Guzman has acknowledged the issue. Other threads claim that there are other displays that have a similar issue, and, within the last 24 hours, some users have experienced luck with modifying their motherboard's settings. I'd expect that it's something the can fix in an upcoming driver, though. For now, I guess plan your monitor outputs accordingly if you were planning on getting the HTC Vive.

Apparently, some people think that AMD will be releasing an RX 490 based on Polaris 10 with an extra four compute units, bringing the total number of stream processors to 2560. I'm guessing that people expected it to be a nice, round number or something, but that's not the case. According to Evan Groenke, Senior Product Manager at AMD, the die has 36 compute units, and there is “nothing else hidden on the product that end users might be looking forward to unlocking”.
Really, this kind-of makes sense. AMD seems to have designed this chip around the performance target of VR, which the RX 480 hits. I don't think that it would really make sense to push about 11% more compute processors into the design, decreasing their yield per wafer for such a relatively small gain.
We are expecting an RX 490 card to land at some point though, thanks to a mistake in publishing on AMD's part. It won't be Polaris 10 or 11.

It appears that MSI will be one of the first AIB partners to get a reference version of the AMD RX 480 graphics card out. Available as soon as next week, the MSI Radeon RX 480 8G pairs AMD’s Polaris-based GPU with 8GB of GDDR5 memory on a reference platform and cooler.
The MSI card uses the AMD reference cooler with a blower style fan and measures 9.45” in length. It is a dual slot design with a red and black aesthetic. Rear IO includes three DisplayPort and one HDMI ports. It is powered by a single 6-pin PCI-E power connector.
There is not much to say with regards to clocks on this GCN4-based card as there are no factory overclocks to speak of. The base clock sits at 1120 MHz (which is an average expected clock, not necessarily the minimum) and the GPU can boost up to a maximum of 1266 MHz out of the box. MSI is clocking the memory at the full 8 GHz though, which is good (AMD stated that partners could clock memory anywhere from seven to eight GHz).
Looking around various retailers, it appears that you will be able to get your hands on it as soon as July 9th from Newegg for $240.
Watch out for pricing before clicking that buy button though, because some sites that allow third party sellers have jacked up the prices quite a bit! If you are looking for a reference design, this card should be as good as the rest. Personally, I am looking forward to MSI and other AIB partner’s custom RX 480 cards which should have much higher overclocking potential and a better power phase setup that should alleviate any power consumption concerns of the reference design’s VRM setup. That is not to say that the reference MSI is going to blow up your PC or anything, but from a buyer's perspective I would rather wait for the custom boards with better coolers that I can push further and faster for only a fairly slight premium. If you need a blower style cooler, this card should work.

Getting a custom-cooled GTX 1080 (for around its MSRP) basically involves monitoring Newegg for a good business week or two, several times per day, pouncing on whatever isn't marked-up. Whether it's low supply or high demand, add-in board vendors haven't stopped announcing new models.
Image Credit: EXPReview
The MSI GTX 1080 8G DUKE is a three-fan (“TriFrozr”) design with an 8-pin and a 6-pin PCIe power connector, which provides 75W more headroom than the Founders Edition. EXPReview claims that it slides between the AERO and the GAMING lines. Although they don't claim how it matches up to ARMOR, which is also between AERO and GAMING, it looks like it's slightly above it, with its RGB LEDs. The GTX 1080 GPU is factory overclocked to 1708 MHz and boosts to 1847 MHz, and the GTX 1070 is overclocked to 1607 MHz with a 1797 MHz boost.
Launch regions are not listed for the cards, but the launch price is supposedly 5399 Chinese Yuan (which converts to $810 USD) and 3499 Chinese Yuan ($524.70 USD) for the GTX 1070. This is quite a bit higher than we would expect, but I'm not sure how regional pricing on electronics works between the USA and China.

Custom graphics cards based on NVIDIA’s GTX 1070 GPU have been rolling out from all the usual suspects, and today small form factor enthusiasts have a new option with Gigabyte’s Mini ITX friendly GTX 1070 Mini ITX OC. As the name implies, this is a factory overclocked card that can hit 1746 MHz boost with the right checkboxes ticked in the company’s vBIOS utility.
The new SFF graphics card measures a mere 6.7-inches long and is a dual slot design with a custom single 90mm fan HSF. It is a custom design that uses a 5+1 power phase design which Gigabyte claims is engineered to provide lower temperatures and more stable voltage compared to Nvidia’s reference design which is a 4+1 setup. The cooler on the dual slot card uses an aluminum fin array that is fed by three direct touch heatpipes. The 90mm fan is able to spin down to 0 rpm when the card is not under load which would make it a good candidate for a gaming capable living room PC that also doubles as your media center. Gigabyte further claims that their "3D stripe" ridged fan blade design helps to reduce noise and improve cooling performance.
Rear IO on the card includes two dual link DVI connectors, one HDMI, and one DisplayPort output. The graphics card is powered by a single 8-pin PCI-E power connector.
As far as the nitty gritty specifications are concerned, Gigabyte has the GTX 1070 GPU clocked out of the box at 1531 MHz base and 1721 MHz boost. Using the company’s Xtreme Engine utility, users can enable the “OC Mode” which automatically clocks the card further to 1556 MHz base and 1746 MHz boost. The OC Mode in particular is a decent factory overclock over the reference clocks of 1506 MHz base and 1683 MHz boost respectively. The 8 GB of GDDR5 memory remains effectively untouched at 8008 MHz.
Unfortunately as is usually the case with these kinds of launches pricing and availability has not yet been announced. From a cursory look around Newegg I would guess that the card will be somewhere around $465 (both the factory overclock and SFF premium).

It is rather difficult to rate the cost to performance ratio of GTX 1080's as the prices and availability are in a constant state of flux but we can certainly peg the overall performance of the cards. [H]ard|OCP recently strapped the new ASUS ROG GTX 1080 STRIX GAMING GPU to their testbed to see how it performs. Right out of the box the cards base clock is 1759MHz with a boost clock of 1898MHz and 10GHz GDDR5X, which [H] successfully raised to 1836MHz base, 1973MHz boost with in game frequencies reaching 2139 MHz and the GDDR5 running at 11.3GHz. This had an effect on performance.
"Today we review in full detail our first custom GeForce GTX 1080 video card. ASUS has decked the ROG GTX 1080 STRIX GAMING out with a factory overclock, the STRIX cooling system, and a fully customizable lighting system. Let's see this beast overclock and compare it to the previous gen's GTX 980 Ti and Radeon R9 Fury X."

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.
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.
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.
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.

If you're trying to purchase a Pascal or Polaris-based GPU, then you are probably well aware that patience is a required virtue. The problem is that, as a hardware website, we don't really know whether the issue is high demand or low supply. Both are manufactured on a new process node, which could mean that yield is a problem. On the other hand, it's been about four years since the last fabrication node, which means that chips got much smaller for the same performance.
Over time, manufacturing processes will mature, and yield will increase. But what about right now? AMD made a very small chip that produces ~GTX 970-level performance. NVIDIA is sticking with their typical, 3XXmm2 chip, which ended up producing higher than Titan X levels of performance.
It turns out that, according to online retailer, Overclockers UK, via Fudzilla, both the RX480 and GTX 1080 have sold over a thousand units at that location alone. That's quite a bit, especially when you consider that it only considers one (large) online retailer from Europe. It's difficult to say how much stock other stores (and regions) received compared to them, but it's still a thousand units in a day.
It's sounding like, for both vendors, pent-up demand might be the dominant factor.

Having already read through Ryan's review of the RX 480 while listening to Raja on the live stream you might be curious what others thought of the card. Perhaps there was one of your preferred configurations or games we did not cover or maybe you just love to read. Do not worry as there are plenty of reviews to test out. You could start over at [H]ard|OCP, who test power usage and performance with a different technique, before moving on to other hardware sites.

AMD's current "We're in the Game" promotion offers a glimpse at upcoming product names, including the Radeon RX 490 graphics card, and the new Bristol Ridge APUs.
Visit AMD's gaming promo page and click the link to "check eligibility" to see the following list of products, which includes the new product names:
It seems safe to assume that the new products listed - including the Radeon RX 490 - are close to release, though details on the high-end Polaris GPU are not mentioned. We do have details on the upcoming Bristol Ridge products, with this in-depth preview from Josh published back in April. The A12-9800 and A12-9800E are said to be the flagship products in this new 7th-gen lineup, so there will be new desktop parts with improved graphics soon.

A report from VideoCardz.com shows what appears to be an NVIDIA GeForce GTX 1060 graphics card with a cooler similar to the "Founders Edition" GTX 1080/1070 design.
Is this the GTX 1060 reference design? (Image via VideoCardz.com)
The image comes via Reddit (original source links in the VideoCardz post), and we cannot verify the validity of the image - though it certainly looks convincing to this writer.
So what does VideoCardz offer as to the specifications of this GTX 1060 card? Quoting from the post:
"NVIDIA GeForce GTX 1060 will most likely use GP106 GPU with at least 1280 CUDA cores. Earlier rumors suggested that GTX 1060 might get 6 GB GDDR5 memory and 192-bit memory bus."
We await official word on the GTX 1060 from NVIDIA, which VideoCardz surmises "is expected to hit the market shortly after Radeon RX 480".

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.

An astute reader spotted several more RX 480's on Newegg, lacking clock speeds but providing physical dimensions, albeit with what looks to be a stock image. All three cards seem to be dual slot designs, XFX's card measuring 10" x 5", ASUS' at 11.8" x 5.4" and Sapphire's a wide bodied 11.8" x 6.5". This could indicate a custom cooler or merely that the cards have rough dimensions listed as opposed to the exact size.
Unfortunately the comparison and details page is unavailable so we don't have a way to see the listed clock speeds but we can be sure that they will have three DP 1.2 ports and an HDMI out. We will keep an eye out for any more leaks we can share with you.

Tagged: SLI HB, nvidia, EVGA SLI HB
Earlier this month we reported that EVGA would be producing its own version of Nvidia's SLI High Bandwidth bridges (aka SLI HB). Today, the company unveiled all the details on its new bridges that we did not know previously, particularly pricing and what the connectors look like.
EVGA is calling the new SLI HB bridges the EVGA Pro SLI HB Bridge and it will be available in several sizes to accommodate your particular card spacing. Note that the 0 slot, 1 slot, 2 slot, and 4 slot spacing bridges are all for two graphics card setups; you will not be able to use these bridges for Tri SLI or Quad SLI setups. While Nvidia did not show the underside of the HB bridges when it first announced them alongside the GTX 1080 graphics card, thanks to EVGA you can finally see what the connectors look like.
As many surmised, the new high bandwidth bridges use both fingers of the SLI connectors on each card to connect the two cards together. Previously (using the old-style SLI bridges), it was possible to connect card A to card B using one set of connectors and Card B to Card C using the second set of connectors for example. Now, you are limited to two card multi-GPU setups. That is the downside; however, the upside is that the HB bridges promise to deliver all of the necessary bandwidth to allow for high speed 4K and NVIDIA Surround display setups. While you will not necessarily see higher frame rates, the HB bridges should allow for improved frame times which will mean smoother gameplay on those very high resolution monitors!
The new SLI bridges are all black with an EVGA logo in the middle that is backlit by an LED. Users are able to use a switch along the bottom edge of the pcb to select from red, green, blue, and white LED colors. In my opinion these bridges look a lot better than the Nvidia SLI HB bridge renders from our computex story (hehe).
Now, as for pricing: EVGA is pricing its SLI HB bridges at $39.99 with the 2 slot spacing and 4 slot spacing bridges available now and the 0 slot and 1 slot spaced bridges set to be available soon (you can sign up to be notified when they are available for purchase). Hopefully reviews will be updated shortly around the net with the new bridges to see what impact they really have on multi-GPU gaming performance (or if they will just be better looking alternatives to the older LED bridges or ribbon bridges)!

The AMD Radeon RX 480 is set to launch on June 29th, but a VisionTek model was published a little early (now unpublished -- thanks to our long-time reader, Arbiter, for the heads up). Basically all specifications were already shared, and Ryan wrote about them on June 1st, but the final clock rates were unknown. The VisionTek one, on the other hand, has it listed as 1120 MHz (5.16 TFLOPs) with a boost of 1266 MHz (5.83 TFLOPs).
Granted, it's possible that the VisionTek model could be overclocked, even though the box and product page doesn't mark it as a factory-overclocked SKU. Also, 5.16 TFLOPs and 5.83 TFLOPs align pretty close to AMD's “>5 TFLOPs” rating, so it's unlikely that the canonical specifications slide underneath this one. Also, TFLOP ratings are basically a theoretical maximum performance, so real-world benchmarks need to be considered for a true measure of performance. That said, this would put the stock RX 480 in the range of a GTX 980 (somewhere above its listed boost clock, and slightly below its expected TFLOP rating when overclocked).
There is no price listed for the 8GB model, but the 4GB version will be $199 USD.

Techspot published an article that compared eight GPUs across six, high-end dies in NVIDIA's last four architectures: Fermi to Pascal. Average frame rates were listed across nine games, each measured at three resolutions:1366x768 (~720p HD), 1920x1080 (1080p FHD), and 2560x1600 (~1440p QHD).
The results are interesting. Comparing GP104 to GF100, mainstream Pascal is typically on the order of four times faster than big Fermi. Over that time, we've had three full generational leaps in fabrication technology, leading to over twice the number of transistors packed into a die that is almost half the size. It does, however, show that prices have remained relatively constant, except that the GTX 1080 is sort-of priced in the x80 Ti category despite the die size placing it in the non-Ti class. (They list the 1080 at $600, but you can't really find anything outside the $650-700 USD range).
It would be interesting to see this data set compared against AMD. It's informative for an NVIDIA-only article, though.

Phoronix wanted to test out how the new GTX 1070 and the R9 Fury compare on Ubuntu with new drivers and patches, as well as contrasting how they perform on Windows 10. There are two separate articles as the focus is not old silicon versus new but the performance comparison between the two operating systems. AMD was tested with the Crimson Edition 16.6.1 driver, AMDGPU-PRO Beta 2 (16.20.3) driver as well as Mesa 12.1-dev. There were interesting differences between the tested games as some would only support one of the two Linux drivers. The performance also varies based on the game engine, with some coming out in ties, others seeing Windows 10 pull ahead and even some cases where your performance on Linux was significantly better.
NVIDIA's GTX 1080 and 1070 were tested using the 368.39 driver release for Windows and the 367.27 driver for Ubuntu. Again we see mixed results, depending on the game Linux performance might actually beat out Windows, especially if OpenGL is an option.
Check out both reviews to see what performance you can expect from your GPU when gaming under Linux.
"Yesterday I published some Windows 10 vs. Ubuntu 16.04 Linux gaming benchmarks using the GeForce GTX 1070 and GTX 1080 graphics cards. Those numbers were interesting with the NVIDIA proprietary driver but for benchmarking this weekend are Windows 10 results with Radeon Software compared to Ubuntu 16.04 running the new AMDGPU-PRO hybrid driver as well as the latest Git code for a pure open-source driver stack."

Tagged: tesla, pascal, nvidia, GP100
GP100, the “Big Pascal” chip that was announced at GTC, will be coming to PCIe for enterprise and supercomputer customers in Q4 2016. Previously, it was only announced using NVIDIA's proprietary connection. In fact, they also gave themselves some lead time with their first-party DGX-1 system, which retails for $129,000 USD, although we expect that was more for yield reasons. Josh calculated that each GPU in that system is worth more than the full wafer that its die was manufactured on.
This brings us to the PCIe versions. Interestingly, they have been down-binned from the NVLink version. The boost clock has been dropped to 1300 MHz, from 1480 MHz, although that is matched with a slightly lower TDP (250W versus the NVLink's 300W). This lowers the FP16 performance to 18.7 TFLOPs, down from 21.2, FP32 performance to 9.3 TFLOPs, down from 10.6, and FP64 performance to 4.7 TFLOPs, down from 5.3. This is where we get to the question: did NVIDIA reduce the clocks to hit a 250W TDP and be compatible with the passive cooling technology that previous Tesla cards utilize, or were the clocks dropped to increase yield?
They are also providing a 12GB version of the PCIe Tesla P100. I didn't realize that GPU vendors could selectively disable HBM2 stacks, but NVIDIA disabled 4GB of memory, which also dropped the bus width to 3072-bit. You would think that the simplicity of the circuit would want to divide work in a power-of-two fashion, but, knowing that they can, it makes me wonder why they did. Again, my first reaction is to question GP100 yield, but you wouldn't think that HBM, being such a small part of the die, is something that they can reclaim a lot of chips by disabling a chunk, right? That is, unless the HBM2 stacks themselves have yield issues -- which would be interesting.
There is also still no word on a 32GB version. Samsung claimed the memory technology, 8GB stacks of HBM2, would be ready for products in Q4 2016 or early 2017. We'll need to wait and see where, when, and why it will appear.

GeForce Hotfix 368.51 drivers have been released by NVIDIA through their support website. This version only officially addresses flickering at high refresh rates, although its number has been incremented quite a bit since the last official release (368.39) so it's possible that it rolls in other changes, too. That said, I haven't heard too many specific issues with 368.39, so I'm not quite sure what that would be.
As always with a hotfix driver, NVIDIA pushed it out with minimal testing. It should pretty much only be installed if you have a specific issue (particularly the listed one(s)) and you don't want to wait until one is released that both NVIDIA and Microsoft looked over (although Microsoft's WHQL certification has been pretty lax since Windows 10).
Oddly enough, they only seem to list 64-bit links for Windows 8.1 and Windows 10. I'm not sure whether this issue doesn't affect Windows 7 and 32-bit versions of 8.1 and 10, or if they just didn't want to push the hotfix out to them for some reason.
