Microsoft and NVIDIA has decided to release some information about DirectX 12 (and DirectX 11.3) alongside the launch of the Maxwell-based GeForce GTX 980 and GeForce GTX 970 graphics cards. Mostly, they announced that Microsoft teamed up with Epic Games to bring DirectX 12 to Unreal Engine 4. They currently have two demos, Elemental and Infiltrator, that are up and running with DirectX 12.

Moreover, they have provided a form for developers who are interested in "early access" to apply for it. They continually discuss it in terms of Unreal Engine 4, but they do not explicitly say that other developers cannot apply. UE4 subscribers will get access to the Elemental demo in DX12, but it does not look like Infiltrator will be available.

DirectX 12 is expected to target games for Holiday 2015.

Fremont, CA (19th September, 2014) - ASUS today announced the STRIX GTX 980 and STRIX GTX 970, all-new gaming graphics cards packed with exclusive ASUS technologies, including DirectCU II and GPU Tweak for cooler, quieter and faster performance. The STRIX GTX 980 and STRIX GTX 970 are factory-overclocked at 1279MHz and 1253MHz respectively and are fitted with 4GB of high-speed GDDR5 video memory operating at speeds up to 7010MHz for the best gameplay experience.

Play League of Legends and StarCraft in silence!
The STRIX GTX 980 and STRIX GTX 970 both come with the ASUS-exclusive DirectCU II cooling technology. With a 10mm a heatpipe to transport heat away from the GPU core, operating temperatures are 30% cooler and 3X quieter than reference designs. Efficient cooling and lower operating temperatures allow STRIX graphics cards to incorporate an intelligent fan-stop mode that can handle games such as League of Legends1 and StarCraft1 passively, making both cards ideal for gamers that prefer high-performance, low-noise PCs.

The answer to the two most important questions are as follows, the GTX 980 will cost you around $560 compared to the $500 for an R9 290X and the GTX 970 an attractive $330 compared to $380 for an R9 290.  Availability is hard to predict but the cards will be shipping soon and you can pre-order your choice of card by following the links on the last page of Ryan's review.  Among all the new features that have been added to this new GPU one of the most impressive is the power draw, as you can see in [H]ard|OCP's review this card pulls 100W less than the 290X at full load although it did run warmer than the 290X Double Dissipation card which [H] compared it to, something that may change with a 980 bearing a custom cooler.  Follow those links to see the benchmarking results of this card, both synthetic and in game.

The GM204 Architecture

James Clerk Maxwell's equations are the foundation of our society's knowledge about optics and electrical circuits. It is a fitting tribute from NVIDIA to include Maxwell as a code name for a GPU architecture and NVIDIA hopes that features, performance, and efficiency that they have built into the GM204 GPU would be something Maxwell himself would be impressed by. Without giving away the surprise conclusion here in the lead, I can tell you that I have never seen a GPU perform as well as we have seen this week, all while changing the power efficiency discussion in as dramatic a fashion.

IMG_9754.JPG

To be fair though, this isn't our first experience with the Maxwell architecture. With the release of the GeForce GTX 750 Ti and its GM107 GPU, NVIDIA put the industry on watch and let us all ponder if they could possibly bring such a design to a high end, enthusiast class market. The GTX 750 Ti brought a significantly lower power design to a market that desperately needed it, and we were even able to showcase that with some off-the-shelf PC upgrades, without the need for any kind of external power.

That was GM107 though; today's release is the GM204, indicating that not only are we seeing the larger cousin of the GTX 750 Ti but we also have at least some moderate GPU architecture and feature changes from the first run of Maxwell. The GeForce GTX 980 and GTX 970 are going to be taking on the best of the best products from the GeForce lineup as well as the AMD Radeon family of cards, with aggressive pricing and performance levels to match. And, for those that understand the technology at a fundamental level, you will likely be surprised by how much power it requires to achieve these goals. Toss in support for things like a new AA method, Dynamic Super Resolution, and even improved SLI performance and you can see why doing it all on the same process technology is impressive.

The NVIDIA Maxwell GM204 Architecture

The NVIDIA Maxwell GM204 graphics processor was built from the ground up with an emphasis on power efficiency. As it was stated many times during the technical sessions we attended last week, the architecture team learned quite a bit while developing the Kepler-based Tegra K1 SoC and much of that filtered its way into the larger, much more powerful product you see today. This product is fast and efficient, but it was all done while working on the same TSMC 28nm process technology used on the Kepler GTX 680 and even AMD's Radeon R9 series of products.

GeForce_GTX_980_Block_Diagram_FINAL.png

The fundamental structure of GM204 is setup like the GM107 product shipped as the GTX 750 Ti. There is an array of GPCs (Graphics Processing Clustsers), each comprised of multiple SMs (Streaming Multiprocessors, also called SMMs for this Maxwell derivative) and external memory controllers. The GM204 chip (the full implementation of which is found on the GTX 980), consists of 4 GPCs, 16 SMMs and four 64-bit memory controllers.

Three Display Component Vendors Support AMD FreeSync

Tagged: amd, freesync, DisplayPort, adaptive sync

MStar, Novatek, and Realtek, three vendors of scaler units for use in displays, have announced support for AMD's FreeSync. Specifically, for the Q1'15 line of monitors, these partners will provide scaler chips that use DisplayPort Adaptive-Sync and, when paired with a compatible AMD GPU, will support FreeSync.

The press release claims that these scalar chips will either support 1080p and 1440p monitors that are up to 144Hz, or drive 4K displays that are up to 60Hz. While this is promising, at least compared to the selection at G-Sync's launch a year earlier, it does not mean that this variety of monitors will be available -- just that internal components will be available for interested display vendors. Also, it means that there are probably interested display vendors.

AMD and partners "intend to reveal" displays via a "media review program" in Q1. This is a little later than what we expected from Richard Huddy's "next month" statements, but it is possible that "Sampling" and "Media Review Program" are two different events. Even if it is "late", this is the sort of thing that is forgivable to me (missing a few months while relying on a standards body and several, independent companies).

Can a heavily overclocked ASUS STRIX GTX 750 Ti OC beat an R9 270?

Subject: Graphics Cards | September 18, 2014 - 12:56 PM |
Tagged: DirectCU II, asus, STRIX GTX 750 Ti OC, factory overclocked

The ASUS STRIX GTX 750 Ti OC sports the custom DirectCU II cooling system which not only improves the temperatures on the card but also reduces the noise produced by the fans.  It comes out of the box with an overclocked  GPU base clock 1124MHz and a boost clock of 1202MHz, with the 2GB of VRAM set to the stock speed of 5.4GHz; [H]ard|OCP managed to increase that to an impressive 1219/1297MHz and 6.0GHz even for the VRAM without increasing voltages.  Unfortunately even with that overclock it lagged behind the Sapphire Radeon R9 270 Dual-X which happens to be about the same price at $170.

"Rounding out our look at ASUS' new STRIX technology we have another STRIX capable video card on our test bench today, this time based on the GTX 750 Ti GPU. We will take the ASUS STRIX GTX 750 Ti OC Edition and test it against an AMD Radeon R9 270 and AMD Radeon R9 265 to see what reigns supreme under $200."

More NVIDIA GeForce GTX 980 Leaked Details

Subject: General Tech, Graphics Cards | September 15, 2014 - 05:02 PM |
Tagged: nvidia, geforce, GTX 980

Details and photographs of the GeForce GTX 980 are leaking on various forums and websites. Based on the Maxwell architecture, it is supposed to be faster and more efficient than Kepler while being manufactured on an identical, 28nm fab process. While we were uncertain before, it now looks like the GTX 980 will be its formal name, as seen in leaked photographs, below.

As expected, the cooler is a continuation of NVIDIA's reference cooler, as seen on recent high-end graphics cards (such as the GeForce Titan). Again, this is not a surprise. The interesting part is that it is rated for about 250W whereas Maxwell is rumored to draw 180W. While the reference card has two six-pin PCIe power connectors, I am curious to see if the excess cooling will lead to interesting overclocks. That is not even mentioning what the AIB partners can do.

Beyond its over-engineering for Maxwell's TDP, it also includes a back plate.

Its display connectors have been hotly anticipated. As you can see above, the GTX 980 has five outputs: three DisplayPort, one HDMI, and one DVI. Which version of HDMI? Which version of DisplayPort? No clue at the moment. There has been some speculation regarding HDMI 2.0, and the DisplayPort 1.3 standard was just released to the public today, but I would be pleasantly surprised if even one of these made it in.

AMD R9 390X Is Rumored Liquid Cooled

Less than a year after the launch of AMD's R9 290X, we are beginning to hear rumors of a follow-up. What is being called the R9 390X, because if it is called anything else, then that was a very short-lived branding scheme, might be liquid cooled. This would be the first single-processor, reference graphics card to have an integrated water cooler. That said, the public evidence is not as firm as I would normally like.

According to Tom's Hardware, Asetek is working on a liquid-cooled design for "an undisclosed OEM". The product is expected to ship during the first half of 2015 and the press release claims that it will "continue Asetek's success in the growing liquid cooling market". Technically, this could be a collaboration with an AIB partner, not necessarily a GPU developer. That said, the leaked photograph looks like a reference card.

We don't really know anything more than this. I would expect that it will be a refresh based on Hawaii, but that is pure speculation. I have no evidence to support that.

Personally, I would hope that a standalone air-cooled model would be available. While I have no experience with liquid cooling, it seems like a bit extra of a burden that not all purchasers of a top-of-the-line single GPU add-in board would want to bare. Specifically, placing the radiator if their case even supports it. That said, having a high-performing reference card will probably make the initial benchmarks look extra impressive, which could be a win in itself.

NCIX and LinusTech Does Four Single GPUs... Twice

Psst. AMD fans. Don't tell "Team Green" but Linus decided to take four R9 290X graphics cards and configure them in Quad Crossfire formation. They did not seem to have too much difficulty setting it up, although they did have trouble with throttling and setting up Crossfire profiles. When they finally were able to test it, they got a 3D Mark Fire Strike Extreme score of 14979.

Psst. NVIDIA fans. Don't tell "Team Red" but Linus decided to take four GeForce Titan Black graphics cards and configure them in Quad SLI formation. He had a bit of a difficult time setting up the machine at first, requiring a reshuffle of the cards (how would reordering PCIe slots for identical cards do anything?) and a few driver crashes, but it worked. Eventually, they got a 3D Mark Fire Strike Extreme score of around 13,300 (give or take a couple hundred).

NVIDIA GM204 info is leaking

Please keep in mind that this information has been assembled via research done by WCCF Tech and Videocardz off of 3DMark entries of unreleased GPUs; we won't get the official numbers until the middle of this month.  That said, rumours and guesswork about new hardware are a favourite past time of our readers so here is the information we've seen so far about the upcoming GM204 chip from NVIDIA.  On the desktop side is the GeForce GTX 980 and GeForce GTX 970 which should both have 4GB of GDDR5 on a 256-bit bus with GPU clock speeds ranging from 1127 to 1190 MHz.  The performance that was shown on 3DMark has the GTX 980 beating the 780 Ti and R9 290X and the GTX 970 performing similarly to the plain GTX 780 and falling behind the 290X.  SLI scaling looks rather attractive with a pair of GTX 980 coming within a hair of the performance of the R9 295X2.

NVIDIA-GeForce-GTX-980-and-GeForce-GTX-970-3DMark-Firestrike-Performance-635x599.png

On the mobile side things look bleak for AMD, the GTX 980M and GTX 970M surpass the current GTX 880M which in turn benchmarks far better than AMD's M290X chip.  Again the scaling in SLI systems will be impressive assuming that the leaks that you can see indepth here are accurate.  It won't be too much longer before we know one way or the other so you might want to keep your finger off of the Buy Button for a short while.
