In a recent press release, Gigabyte announced that it will soon be adding four new GTX 1060 graphics cards to its lineup. The new cards feature Windforce series coolers and custom PCBs. At the high end is the GTX 1060 G1 Gaming followed by the GTX 1060 Windforce OC, small form factor friendly GTX 1060 Mini ITX OC, and the budget minded GTX 1060 D5. While the company has yet to divulge pricing or availability, the cards should be out within the next month or two.
All of the upcoming cards use a custom design that uses a custom PCB and power phase setup paired with Gigabyte's dual – or in the case of the Mini ITX card – single fan Windforce air cooler. Unfortunately, exact specifications for all of the cards except the high end model are unknown including core and memory clocks. The coolers use a dual composite heatpipe that directly touches the GPU to pull heat away and is dissipated by an aluminum fin stack. The fans are 90mm on all of the cards with the dual fan models using a design that has each fan spinning alternate directions of the other. The cards feature 6GB of GDDR5 memory as well as DVI, HDMI, and DisplayPort video outputs. For example, the Mini ITX OC graphics card (which is only 17cm long) and features two DVI, one HDMI, and one DP output.
More information is available on the GTX 1060 G1 Gaming. This card is a dual slot dual fan design with a 6+1 power phase (reference is 3+1) powered by a single 8-pin power connector. The fans are shrouded and there is a metal backplate to aid in stability and cooling. Gigabyte claims that its "GPU Gauntlet" technology ensures users get heavily overclockable chips thanks to sorting and using the most promising chips.
The 16nm Pascal GPU is factory overclocked to 1847 MHz boost and 1620 MHz base clockspeeds in OC mode and 1809 MHz boost and 1594 MHz base in gaming mode. Users will be able to use the company's Xtreme Engine software to dial up the overclocks further as well as mess with the RGB LEDs. For comparison, the reference clockspeeds are 1708 MHz boost and 1506 MHz base. Gigabyte has left the 6GB of GDDR5 memory untouched at 8008 MHz.
The other cards should have similarly decent factory overclocks, but it is hard to say exactly what they will be out of the box. While I am not a big fan of the aesthetics, the Windforce coolers should let users push Pascal fairly far (for air cooling).
I would guess that the Gigabyte GTX 1060 G1 Gaming will MSRP for just above $300 while the lower end cards will be around $260 (the Mini ITX OC may be at a slight premium above that).
What do you think about Gigabyte's new cards?

Turns out the Pascal-based GPUs suffered from DPC latency issues, and there's been an ongoing discussion about it for a little over a month. This is not an area that I know a lot about, but it's a system that schedules workloads by priority, which provides regular windows of time for sound and video devices to update. It can be stalled by long-running driver code, though, which could manifest as stutter, audio hitches, and other performance issues. With a 10-series GeForce device installed, users have reported that this latency increases about 10-20x, from ~20us to ~300-400us. This can increase to 1000us or more under load. (8333us is ~1 whole frame at 120FPS.)
NVIDIA has acknowledged the issue and, just yesterday, released an optional hotfix. Upon installing the driver, while it could just be psychosomatic, the system felt a lot more responsive. I ran LatencyMon (DPCLat isn't compatible with Windows 8.x or Windows 10) before and after, and the latency measurement did drop significantly. It was consistently the largest source of latency, spiking in the thousands of microseconds, before the update. After the update, it was hidden by other drivers for the first night, although today it seems to have a few spikes again. That said, Microsoft's networking driver is also spiking in the ~200-300us range, so a good portion of it might be the sad state of my current OS install. I've been meaning to do a good system wipe for a while...
Measurement taken after the hotfix, while running Spotify.
That said, my computer's a mess right now.
That said, some of the post-hotfix driver spikes are reaching ~570us (mostly when I play music on Spotify through my Blue Yeti Pro). Also, Photoshop CC 2015 started complaining about graphics acceleration issues after installing the hotfix, so only install it if you're experiencing problems. About the latency, if it's not just my machine, NVIDIA might still have some work to do.
It does feel a lot better, though.

Donning the leather jacket he goes very few places without, NVIDIA CEO Jen-Hsun Huang showed up at an AI meet-up at Stanford this evening to show, for the very first time, a graphics card based on a never before seen Pascal GP102 GPU.
Source: Twitter (NVIDIA)
Rehashing an old name, NVIDIA will call this new graphics card the Titan X. You know, like the "new iPad" this is the "new TitanX." Here is the data we know about thus far:
|Titan X (Pascal)||GTX 1080||GTX 980 Ti||TITAN X||GTX 980||R9 Fury X||R9 Fury||R9 Nano||R9 390X|

Note: everything with a ? on is educated guesses on our part.
Obviously there is a lot for us to still learn about this new GPU and graphics card, including why in the WORLD it is still being called Titan X, rather than...just about anything else. That aside, GP102 will feature 40% more CUDA cores than the GP104 at slightly lower clock speeds. The rated 11 TFLOPS of single precision compute of the new Titan X is 34% better than that of the GeForce GTX 1080 and I would expect gaming performance to scale in line with that difference.
The new Titan X will feature 12GB of GDDR5X memory, not HBM as the GP100 chip has, so this is clearly a new chip with a new memory interface. NVIDIA claims it will have 480 GB/s of bandwidth, and I am guessing is built on a 384-bit memory controller interface running at the same 10 Gbps as the GTX 1080. It's truly amazing hardware.
What will you be asked to pay? $1200, going on sale on August 2nd, and only on NVIDIA.com, at least for now. Considering the prices of GeForce GTX 1080 cards with such limited availability, the $1200 price tag MIGHT NOT seem so insane. That's higher than the $999 starting price of the Titan X based on Maxwell in March of 2015 - the claims that NVIDIA is artificially raising prices of cards in each segment will continue, it seems.
I am curious about the TDP on the new Titan X -
will it hit the 250 watt mark of the previous version? Yes, apparently it will it that 250 watt TDP - specs above updated. Does this also mean we'll see a GeForce GTX 1080 Ti that falls between the GTX 1080 and this new Titan X? Maybe, but we are likely looking at an $899 or higher SEP - so get those wallets ready.
That's it for now; we'll have a briefing where we can get more details soon, and hopefully a review ready for you on August 2nd when the cards go on sale!

Phoronix took a look at how NVIDIA's mid range cards performance on Linux has changed over the past four generations of GPU, from Fermi, through Kepler, Maxwell, and finally Pascal. CS:GO was run at 4k to push the newer GPUs as was DOTA, much to the dismay of the GTX 460. The scaling is rather interesting, there is a very large delta between Fermi and Kepler which comes close to being replicated when comparing Maxwell to Pascal. From the looks of the vast majority of the tests, the GTX 1060 will be a noticeable upgrade for Linux users no matter which previous mid range card they are currently using. We will likely see a similar article covering AMD in the near future.
"To complement yesterday's launch-day GeForce GTX 1060 Linux review, here are some more benchmark results with the various NVIDIA x60 graphics cards I have available for testing going back to the GeForce GTX 460 Fermi. If you are curious about the raw OpenGL/OpenCL/CUDA performance and performance-per-Watt for these mid-range x60 graphics cards from Fermi, Kepler, Maxwell, and Pascal, here are these benchmarks from Ubuntu 16.04 Linux."

The GTX 1060 Founders Edition has arrived and also happens to be our first look at the 16nm FinFET GP106 silicon, the GTX 1080 and 1070 used GP104. This card features 10 SMs, 1280 CUDA cores, 48 ROPs and 80 texture units, in many ways it is a half of a GTX 1080. The GPU is clocked at a base of 1506MHz with a boost of 1708MHz, the 6GB of VRAM at 8GHz. [H]ard|OCP took this card through its paces, contrasting it with the RX480 and the GTX 980 at resolutions of 1440p as well as the more common 1080p. As they do not use the frame rating tools which are the basis of our graphics testing of all cards, including the GTX 1060 of course, they included the new DOOM in their test suite. Read on to see how they felt the card compared to the competition ... just don't expect to see a follow up article on SLI performance.
"NVIDIA's GeForce GTX 1060 video card is launched today in the $249 and $299 price point for the Founders Edition. We will find out how it performs in comparison to AMD Radeon RX 480 in DOOM with the Vulkan API as well as DX12 and DX11 games. We'll also see how a GeForce GTX 980 compares in real world gaming."

Twelve days ago, NVIDIA announced its competitor to the AMD Radeon RX 480, the GeForce GTX 1060, based on a new Pascal GPU; GP 106. Though that story was just a brief preview of the product, and a pictorial of the GTX 1060 Founders Edition card we were initially sent, it set the community ablaze with discussion around which mainstream enthusiast platform was going to be the best for gamers this summer.
Today we are allowed to show you our full review: benchmarks of the new GeForce GTX 1060 against the likes of the Radeon RX 480, the GTX 970 and GTX 980, and more. Starting at $250, the GTX 1060 has the potential to be the best bargain in the market today, though much of that will be decided based on product availability and our results on the following pages.
Does NVIDIA’s third consumer product based on Pascal make enough of an impact to dissuade gamers from buying into AMD Polaris?
All signs point to a bloody battle this July and August and the retail cards based on the GTX 1060 are making their way to our offices sooner than even those based around the RX 480. It is those cards, and not the reference/Founders Edition option, that will be the real competition that AMD has to go up against.
First, however, it’s important to find our baseline: where does the GeForce GTX 1060 find itself in the wide range of GPUs?

Tagged: Volta, pascal, nvidia, maxwell, 16nm
For the past few generations, NVIDIA has been roughly trying to release a new architecture with a new process node, and release a refresh the following year. This ran into a hitch as Maxwell was delayed a year, apart from the GTX 750 Ti, and then pushed back to the same 28nm process that Kepler utilized. Pascal caught up with 16nm, although we know that some hard, physical limitations are right around the corner. The lattice spacing for silicon at room temperature is around ~0.5nm, so we're talking about features the size of ~the low 30s of atoms in width.
This rumor claims that NVIDIA is not trying to go with 10nm for Volta. Instead, it will take place on the same, 16nm node that Pascal is currently occupying. This is quite interesting, because GPUs scale quite well with complexity changes, as they have many features with a relatively low clock rate, so the only real ways to increase performance are to make the existing architecture more efficient, or make a larger chip.
That said, GP100 leaves a lot of room on the table for an FP32-optimized, ~600mm2 part to crush its performance at the high end, similar to how GM200 replaced GK110. The rumored GP102, expected in the ~450mm2 range for Titan or GTX 1080 Ti-style parts, has some room to grow. Like GM200, however, it would also be unappealing to GPU compute users who need FP64. If this is what is going on, and we're totally just speculating at the moment, it would signal that enterprise customers should expect a new GPGPU card every second gaming generation.
That is, of course, unless NVIDIA recognized ways to make the Maxwell-based architecture significantly more die-space efficient in Volta. Clocks could get higher, or the circuits themselves could get simpler. You would think that, especially in the latter case, they would have integrated those ideas into Maxwell and Pascal, though; but, like HBM2 memory, there might have been a reason why they couldn't.
We'll need to wait and see. The entire rumor could be crap, who knows?
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.
Let’s take a quick look at the card’s details.
|GTX 1060||RX 480||R9 390||R9 380||GTX 980||GTX 970||GTX 960||R9 Nano||GTX 1070|
|GPU||GP106||Polaris 10||Grenada||Tonga||GM204||GM204||GM206||Fiji XT||GP104|
|Rated Clock||1506 MHz||1120 MHz||1000 MHz||970 MHz||1126 MHz||1050 MHz||1126 MHz||up to 1000 MHz||1506 MHz|

|ROP Units||48 (?)||32||64||32||64||56||32||64||64|
|Memory Clock||8000 MHz||7000 MHz
|6000 MHz||5700 MHz||7000 MHz||7000 MHz||7000 MHz||500 MHz||8000 MHz|
|Memory Interface||192-bit||256-bit||512-bit||256-bit||256-bit||256-bit||128-bit||4096-bit (HBM)||256-bit|
|Memory Bandwidth||192 GB/s||224 GB/s
|384 GB/s||182.4 GB/s||224 GB/s||196 GB/s||112 GB/s||512 GB/s||256 GB/s|
|TDP||120 watts||150 watts||275 watts||190 watts||165 watts||145 watts||120 watts||275 watts||150 watts|
|Peak Compute||3.85 TFLOPS||5.1 TFLOPS||5.1 TFLOPS||3.48 TFLOPS||4.61 TFLOPS||3.4 TFLOPS||2.3 TFLOPS||8.19 TFLOPS||5.7 TFLOPS|
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.

Normally, I pose these sorts of rumors as “Well, here you go, and here's a grain of salt.” This one I'm fairly sure is bogus, at least to some extent. I could be wrong, but especially the GP100 aspects of it just doesn't make sense.
Before I get to that, the rumor is that NVIDIA will announce a GeForce GTX Titan P at Gamescom in Germany. The event occurs mid-August (17th - 21st) and it has been basically Europe's E3 in terms of gaming announcements. It also overlaps with Europe's Game Developers Conference (GDC), which occurs in March for us. The rumor says that it will use GP100 (!?!) with either 12GB of VRAM, 16GB of VRAM, or two variants as we've seen with the Tesla P100 accelerator.
The rumor also acknowledges the previously rumored GP102 die, claims that it will be for the GTX 1080 Ti, and suggests that it will have up to 3840 CUDA cores. This is the same number of CUDA cores as the GP100, which is where I get confused. This would mean that NVIDIA made a special die, which other rumors claim is ~450mm2, for just the GeForce GTX 1080 Ti.
I mean, it's possible that NVIDIA would split the GTX 1080 Ti and the next Titan by similar gaming performance, just with better half- and double-precision performance and faster memory for GPGPU developers. That would be a very weird to me, though, developing two different GPU dies for the consumer market with probably the same gaming performance.
And they would be announcing the Titan P first???
The harder to yield one???
When the Tesla version isn't even expected until Q4???
I can see it happening, but I seriously doubt it. Something may be announced, but I'd have to believe it will be at least slightly different from the rumors that we are hearing now.

Tagged: pascal, nvidia, htc vive, GTX 1080, gtx 1070, GP104
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.
