MSI has updated their gaming notebook lineup with the new NVIDIA Pascal mobile GPUs, with the GTX 1080, GTX 1070, and GTX 1060 now available across the board. MSI says the new GPUs will provide up to 40% better performance than the company’s previous GT, GS, and GE models.
“MSI’s GT83/73VR Titan series now showcases an even more commanding design with sports car inspired exhausts and MSI’s Cooler Boost Titan, featuring multiple exhausts and dual whirlwind blade fans to guarantee the best performance even under the most stress. Available in 3 different sizes and 17 unique configurations, including with SLI graphics, 4K panels and Tobii’s eye-tracking technology, MSI’s GT series is the optimum laptop for serious gamers.”
Positioned at the top of the heap is the mighty Titan series, which naturally offers the highest possible specs for those who can afford the price tag.
Notice anything about the top-end GT83 model in the chart above? The GT83VR Titan SLI indeed contains not one, but two NVIDIA GTX 1080 graphics chips, making this $5099 gaming machine a monster of a system - though its 1080p screen real estate means a connected VR headset will be more likely to use all of that available GPU power.
Moving down to the GT72/GT62 series, we see a move to the GTX 1070 GPU accross the board:
Next up is the GS73, which offers (in addition to Pascal graphics) MSI's "Cooler Boost Trinity", which is the company's advanced cooling system for thin notebook designs.
“MSI’s redesigned GS73/63 VR Stealth Pro series now comes with MSI’s Cooler Boost Trinity, a temperature control system featuring three ultra-thin whirlwind blade fans, and a 5-pipe thermal design optimized for ultra-slim gaming notebooks. Available in 17-inch, 15-inch, and 14-inch options, MSI’s GS series gives power mobile gaming a new meaning with the performance of larger systems while measuring less than 1-inch thick.”
The more modest GTX 1060 powers the <1 inch thick notebooks in the series, and both the GS73 and GS63 VR Stealth Pro are equipped with 4K resolution IPS screens (with the GS43VR Phantom Pro at 1080p).
Next we have the VR Apache series, with another approach to cooling called "Cooler Boost 4":
“MSI’s GE72/62 VR Apache series now features MSI’s Cooler Boost 4 technology, an enhanced cooling system with multiple exhausts to keep temperatures low even during the most headed battles. Starting at $1,649, the VR-ready GE series comes in two different sizes and is the ideal unit for gaming enthusiast looking for a powerful and reliable unit.”
These lower-cost gaming machines are still equipped with Intel Core i7 processors, and offer GTX 1060 graphics for both models.
As a very interesting addition to the news of these new laptops, MSI has also announced that select machines equipped with NVIDIA GTX 10 Series graphics will feature 120Hz IPS panels with a 5ms response time.
We should have more imformation on availability soon.
Take your Pascal on the go
Easily the strongest growth segment in PC hardware today is in the adoption of gaming notebooks. Ask companies like MSI and ASUS, even Gigabyte, as they now make more models and sell more units of notebooks with a dedicated GPU than ever before. Both AMD and NVIDIA agree on this point and it’s something that AMD was adamant in discussing during the launch of the Polaris architecture.
Both AMD and NVIDIA predict massive annual growth in this market – somewhere on the order of 25-30%. For an overall culture that continues to believe the PC is dying, seeing projected growth this strong in any segment is not only amazing, but welcome to those of us that depend on it. AMD and NVIDIA have different goals here: GeForce products already have 90-95% market share in discrete gaming notebooks. In order for NVIDIA to see growth in sales, the total market needs to grow. For AMD, simply taking back a portion of those users and design wins would help its bottom line.
But despite AMD’s early talk about getting Polaris 10 and 11 in mobile platforms, it’s NVIDIA again striking first. Gaming notebooks with Pascal GPUs in them will be available today, from nearly every system vendor you would consider buying from: ASUS, MSI, Gigabyte, Alienware, Razer, etc. NVIDIA claims to have quicker adoption of this product family in notebooks than in any previous generation. That’s great news for NVIDIA, but might leave AMD looking in from the outside yet again.
Technologically speaking though, this makes sense. Despite the improvement that Polaris made on the GCN architecture, Pascal is still more powerful and more power efficient than anything AMD has been able to product. Looking solely at performance per watt, which is really the defining trait of mobile designs, Pascal is as dominant over Polaris as Maxwell was to Fiji. And this time around NVIDIA isn’t messing with cut back parts that have brand changes – GeForce is diving directly into gaming notebooks in a way we have only seen with one release.
The ASUS G752VS OC Edition with GTX 1070
Do you remember our initial look at the mobile variant of the GeForce GTX 980? Not the GTX 980M mind you, the full GM204 operating in notebooks. That was basically a dry run for what we see today: NVIDIA will be releasing the GeForce GTX 1080, GTX 1070 and GTX 1060 to notebooks.

NVIDIA will offer a 3GB version of the GTX 1060, and there's more to the story than the obvious fact that is has half the frame buffer of the 6GB version available now. It appears that this is an entirely different product, with 128 fewer CUDA cores (1152) than the 6GB version's 1280.

Boost clocks are the same at 1.7 GHz, and the 3GB version will still operate with a 120W TDP and require a 6-pin power connector. So why not simply name this product differently? It's always possible that this will be an OEM version of the GTX 1060, but in any case expect slightly lower performance than the existing version even if you don't run at high enough resolutions to require the larger 6GB frame buffer.

Corsair and MSI have teamed up once again to produce a liquid-cooled edition of the latest NVIDIA GPU, with the GTX 1080 receiving the same treatment these two gave to the Hydro GFX version of GTX 980 Ti last year.
“The CORSAIR Hydro GFX GTX 1080 brings all the benefits of liquid cooling to the GeForce GTX 1080, boasting an integrated CORSAIR Hydro Series H55 cooler that draws heat from the GPU via a micro-fin copper base cold plate and dissipates it efficiently using a 120mm high-surface area radiator. A pre-installed low-noise LED-lit 120mm fan ensures steady, reliable air-flow, keeping GPU temperatures down and clock speeds high.
With a low-profile PCB and pre-fitted, fully-sealed liquid cooler, the Hydro GFX GTX 1080 is simple and easy to install. Just fit the card into a PCI-E 3.0 x16 slot, mount the radiator and enjoy low maintenance liquid cooling for the lifetime of the card.”
Naturally, with an integrated closed-loop liquid cooler this GTX 1080 won't be relegated to stock speeds out of the box, though Corsair leaves this up to the user. The card offers three performance modes which allow users to choose between lower noise and higher performance. Silent Mode leaves the GTX 1080 at stock settings (1733 MHz Boost), Gaming Mode increases the Boost clock to 1822 MHz, and OC Mode increases this slightly to 1847 MHz (while increasing memory speed in this mode as well).
This liquid-cooled version will provide higher sustained clocks

When [H]ard|OCP looks at the performance of a VR game, be it a Vive or Rift title, they focus on the gameplay experience as opposed to benchmarks. There are numerous reasons for this, from the fact that these games do not tend to stress GPUs like many triple A titles but also because the targets are different, steady render times below 11.1ms are the target as opposed to higher frame counts. AMD initially had issues with this game, the newest driver release has resolved those issues completely. The takeaway quote in [H]'s conclusions provide the most telling part of the review, "If we were to perform a blind gaming test, you would not be able to identify which GPU you were gaming with at the time."
"We are back this week to take another objective look at AMD and NVIDIA GPU performance in one of the the top selling games in the VR-only realm, The Gallery Episode 1: Call of Starseed. This is another GPU-intensive title that has the ability to put some GPUs on their heels. How do the new RX 480 and GeForce 1000 series perform?"

Tagged: htc vive, amd, nvidia, raw data
Raw Data is an early access game for the HTC Vive, one which requires space to move and which allows the Vive to show off its tracking ability. [H]ard|OCP wanted to see how the GPUs found in most high end systems would perform in this VR game and so grabbed several AMD and NVIDIA cards to test out. Benchmarking VR games is not an easy task, instead of raw performance you need to focus on the dropped frames and unstable fps which result in nausea and a less engrossing VR experience. To that end [H] has played the game numerous times on a variety of GPUs with settings changing throughout to determine the sweet spot for the GPU you are running. VR offers a new gaming experience and new tests need to be developed to demonstrate performance to those interested in jumping into the new market. Check out the full review to see what you think of their methodology as well as the raw performance of the cards.
"Both AMD and NVIDIA have had a lot to say about "VR" for a while now. VR is far from mainstream, but we are now seeing some games that are tremendously compelling to play, putting you in middle of the action. Raw Data is one of those, and it is extremely GPU intensive. How do the newest GPUs stack up in Raw Data?"

A Beautiful Graphics Card
As a surprise to nearly everyone, on July 21st NVIDIA announced the existence of the new Titan X graphics cards, which are based on the brand new GP102 Pascal GPU. Though it shares a name, for some unexplained reason, with the Maxwell-based Titan X graphics card launched in March of 2015, this is card is a significant performance upgrade. Using the largest consumer-facing Pascal GPU to date (with only the GP100 used in the Tesla P100 exceeding it), the new Titan X is going to be a very expensive, and very fast gaming card.
As has been the case since the introduction of the Titan brand, NVIDIA claims that this card is for gamers that want the very best in graphics hardware as well as for developers and need an ultra-powerful GPGPU device. GP102 does not integrate improved FP64 / double precision compute cores, so we are basically looking at an upgraded and improved GP104 Pascal chip. That’s nothing to sneeze at, of course, and you can see in the specifications below that we expect (and can now show you) Titan X (Pascal) is a gaming monster.
|Titan X (Pascal)||GTX 1080||GTX 980 Ti||TITAN X||GTX 980||R9 Fury X||R9 Fury||R9 Nano||R9 390X|
|GPU||GP102||GP104||GM200||GM200||GM204||Fiji XT||Fiji Pro||Fiji XT||Hawaii XT|
|Rated Clock||1417 MHz||1607 MHz||1000 MHz||1000 MHz||1126 MHz||1050 MHz||1000 MHz||up to 1000 MHz||1050 MHz|
|Memory Clock||10000 MHz||10000 MHz||7000 MHz||7000 MHz||7000 MHz||500 MHz||500 MHz||500 MHz||6000 MHz|
|Memory Interface||384-bit G5X||256-bit G5X||384-bit||384-bit||256-bit||4096-bit (HBM)||4096-bit (HBM)||4096-bit (HBM)||512-bit|
|Memory Bandwidth||480 GB/s||320 GB/s||336 GB/s||336 GB/s||224 GB/s||512 GB/s||512 GB/s||512 GB/s||320 GB/s|
|TDP||250 watts||180 watts||250 watts||250 watts||165 watts||275 watts||275 watts||175 watts||275 watts|
|Peak Compute||11.0 TFLOPS||8.2 TFLOPS||5.63 TFLOPS||6.14 TFLOPS||4.61 TFLOPS||8.60 TFLOPS||7.20 TFLOPS||8.19 TFLOPS||5.63 TFLOPS|
GP102 features 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% higher than that of the GeForce GTX 1080 and I would expect gaming performance to scale in line with that difference.
Titan X (Pascal) does not utilize the full GP102 GPU; the recently announced Pascal P6000 does, however, which gives it a CUDA core count of 3,840 (256 more than Titan X).
A full GP102 GPU
The complete GPU effectively loses 7% of its compute capability with the new Titan X, although that is likely to help increase available clock headroom and yield.
The new Titan X will feature 12GB of GDDR5X memory, not HBM as the GP100 chip has, so this is clearly a unique chip with a new memory interface. NVIDIA claims it has 480 GB/s of bandwidth on a 384-bit memory controller interface running at the same 10 Gbps as the GTX 1080.
Realworldtech with Compelling Evidence
Yesterday David Kanter of Realworldtech posted a pretty fascinating article and video that explored the two latest NVIDIA architectures and how they have branched away from the traditional immediate mode rasterization units. It has revealed through testing that with Maxwell and Pascal NVIDIA has gone to a tiling method with rasterization. This is a somewhat significant departure for the company considering they have utilized the same basic immediate mode rasterization model since the 90s.

Tiling is an interesting subject and we can harken back to the PowerVR days to see where it was first implemented. There are many advantages to tiling and deferred rendering when it comes to overall efficiency in power and memory bandwidth. These first TBDR (Tile Based Deferred Renderers) offered great performance per clock and could utilize slower memory as compared to other offerings of the day (namely Voodoo Graphics). There were some significant drawbacks to the technology. Essentially a lot of work had to be done by the CPU and driver in scene setup and geometry sorting. On fast CPU systems the PowerVR boards could provide very good performance, but it suffered on lower end parts as compared to the competition. This is a very simple explanation of what is going on, but the long and short of it is that TBDR did not take over the world due to limitations in its initial implementations. Traditional immediate mode rasters would improve in efficiency and performance with aggressive Z checks and other optimizations that borrow from the TBDR playbook.
Tiling is also present in a lot of mobile parts. Imagination’s PowerVR graphics technologies have been implemented by others such as Intel, Apple, Mediatek, and others. Qualcomm (Adreno) and ARM (Mali) both implement tiler technologies to improve power consumption and performance while increasing bandwidth efficiency. Perhaps most interestingly we can remember back to the Gigapixel days with the GP-1 chip that implemented a tiling method that seemed to work very well without the CPU hit and driver overhead that had plagued the PowerVR chips up to that point. 3dfx bought Gigapixel for some $150 million at the time. That company then went on to file bankruptcy a year later and their IP was acquired by NVIDIA.
Screenshot of the program used to uncover the tiling behavior of the rasterizer.
It now appears as though NVIDIA has evolved their raster units to embrace tiling. This is not a full TBDR implementation, but rather an immediate mode tiler that will still break up the scene in tiles but does not implement deferred rendering. This change should improve bandwidth efficiency when it comes to rasterization, but it does not affect the rest of the graphics pipeline by forcing it to be deferred (tessellation, geometry setup and shaders, etc. are not impacted). NVIDIA has not done a deep dive on this change for editors, so we do not know the exact implementation and what advantages we can expect. We can look at the evidence we have and speculate where those advantages exist.
The video where David Kanter explains his findings
Bandwidth and Power
Tilers have typically taken the tiled regions and buffered them on the chip. This is a big improvement in both performance and power efficiency as the raster data does not have to be cached and written out to the frame buffer and then swapped back. This makes quite a bit of sense considering the overall lack of big jumps in memory technologies over the past five years. We have had GDDR-5 since 2007/2008. The speeds have increased over time, but the basic technology is still much the same. We have seen HBM introduced with AMD’s Fury series, but large scale production of HBM 2 is still to come. Samsung has released small amounts of HBM 2 to the market, but not nearly enough to handle the needs of a mass produced card. GDDR-5X is an extension of GDDR-5 that does offer more bandwidth, but it is still not a next generation memory technology like HBM 2.
By utilizing a tiler NVIDIA is able to lower memory bandwidth needs for the rasterization stage. Considering that both Maxwell and Pascal architectures are based on GDDR-5 and 5x technologies, it makes sense to save as much bandwidth as possible where they can. This is again probably one, among many, of the reasons that we saw a much larger L2 cache in Maxwell vs. Kepler (2048 KB vs. 256KB respectively). Every little bit helps when we are looking at hard, real world bandwidth limits for a modern GPU.
The area of power efficiency has also come up in discussion when going to a tiler. Tilers have traditionally been more power efficient as well due to how the raster data is tiled and cached, requiring fewer reads and writes to main memory. The first impulse is to say, “Hey, this is the reason why NVIDIA’s Maxwell was so much more power efficient than Kepler and AMD’s latest parts!” Sadly, this is not exactly true. The tiler is more power efficient, but it is a small part to the power savings on a GPU.
The second fastest Pascal based card...
A modern GPU is very complex. There are some 7.2 billion transistors on the latest Pascal GP-104 that powers the GTX 1080. The vast majority of those transistors are implemented in the shader units of the chip. While the raster units are very important, they are but a fraction of that transistor budget. The rest is taken up by power regulation, PCI-E controllers, and memory controllers. In the big scheme of things the raster portion is going to be dwarfed in power consumption by the shader units. This does not mean that they are not important though. Going back to the hated car analogy, one does not achieve weight savings by focusing on one aspect alone. It is going over every single part of the car and shaving ounces here and there, and in the end achieving significant savings by addressing every single piece of a complex product.
This does appear to be the long and short of it. This is one piece of a very complex ASIC that improves upon memory bandwidth utilization and power efficiency. It is not the whole story, but it is an important part. I find it interesting that NVIDIA did not disclose this change to editors with the introduction of Maxwell and Pascal, but if it is transparent to users and developers alike then there is no need. There is a lot of “secret sauce” that goes into each architecture, and this is merely one aspect. The one question that I do have is how much of the technology is based upon the Gigapixel IP that 3dfx bought at such a premium? I believe that particular tiler was an immediate mode renderer as well due to it not having as many driver and overhead issues that PowerVR exhibited back in the day. Obviously it would not be a copy/paste of the technology that was developed back in the 90s, it would be interesting to see if it was the basis for this current implementation.

Update @ 9:45pm: I heard that some AMD users were notified about their R9 purchase as well, calling it simply "R9". Since I didn't see concrete proof, I omit it from the post in case it was a hoax (as the story is still developing). I have since been notified of a tweet with an email screenshot.
Original post below:
Apparently, Newegg is informing customers that NVIDIA has settled a class action lawsuit with customers of the GeForce GTX 960 and GTX 980 cards, along with the GTX 970. It's currently unclear whether this is an error, or whether this is one of the sibling class action lawsuits that were apparently bundled together with the GTX 970 one. Users on the NVIDIA Reddit are claiming that it has to do with DirectX 12 feature level support, although that seems like knee-jerk confirmation bias to me.
Regardless, if you purchased a GeForce 900-series graphics card from Newegg, maybe even including the 980 Ti, then you should check your email. You might have a settlement en-route.
That's all we know at this point, though. Thanks to our readers for pointing this out.

VideoCardz is reporting that an official announcement of the rumored mobile GPUs might be coming at Gamescom later this month.
"Mobile Pascal may arrive at Gamescom in Europe. According to DigiTimes, NVIDIA would allow its notebook partners to unveil mobile Pascal between August 17th to 21st, so just when Gamescom is hosted is hosted in Germany."
We had previously reported on the rumors of a mobile GTX 1070 and 1060, and we can only assume a 1080 will also be available (though VideoCardz is not speculating on the specs of this high-end mobile card just yet).

Gamescom runs from August 17 - 21 in Germany, so we only have to wait about three weeks to know for sure.
