NVIDIA has impressed the world with the launch of its second generation Maxwell-based GPUs, the GeForce GTX 970 and GTX 980. The cards sip power compared to their already power conservative predecessors, but introduce a slew of new technologies, features and best of all: a great price point. Where to from here? GM200, that's where.
GM200 is now being teased, which is going to be the big new GPU from NVIDIA. NVIDIA's GM200 will feature a die size of 551mm^2, 20-22 SMMs, 2560-2816 CUDA cores, a 384-bit memory bus, a performance boost of around 50% over the GTX Titan Black Edition, with it launching sometime before the end of the year. What it'll arrive as, in terms of naming, is a mystery. With the power efficiency of the GM204 core, which powers the GTX 970 and GTX 980, we should expect a dual-GPU card offered as the GeForce GTX 990, so that's one name it won't use.
Moving on, we could expect it to be the GTX 980 Ti, but if it's offering a huge performance increase over the GTX Titan Black Edition, we might see something like the GTX 985 Ti, or GTX Titan X, something I like the sound of better. Then we have the shift to 20nm, which is expected next year, so if the new GM200 is built on the current 28nm node, the shift to 20nm is going to be an entire new world for NVIDIA. The company has positioned themselves incredibly well after the mess that was Fermi, so much so, that AMD really has no firepower right now - so it'll be interesting to see if NVIDIA holds back, waiting for AMD to release something, to quickly smack it down to reality with its new GM200-based card.
NVIDIA Editor's Day 2014 - NVIDIA had some truly impressive technology to showcase during its Editor's Day in the beautiful Monterey Bay in California, where the technology giant proved that the Moon landings weren't faked, thanks to its new Voxel Global Illumination technology.
Voxel Global Illumination, or VGXI, is dynamic, with 'no baking required' according to NVIDIA. It works on Epic Games' Unreal Engine 4, and other major engines (in Q4 of this year) and uses one-bounce indirect diffuse, specular, reflections, area lights and much more.
NVIDIA were bashing conspiracy theorists, as many of them say the Moon landings were faked. Due to the power found in its Maxwell architecture, VXGI comes alive, and is able to do some truly incredible real-time lighting to prove how light was reflecting off of the lunar surface, lighting up various objects, Neil Armstrong and Buzz Aldrin, as well as the lunar module itself.
This shot, has the real image side-by-side with the rendered image. I'll let you try and work out which one is which, so let us know in the comments section below.
NVIDIA Editor's Day 2014 - NVIDIA's G-SYNC technology is something I've truly embraced, sitting in front of the ASUS ROG Swift monitor right now as I type this, but 4K G-SYNC? Sign. Me. Up.
In Monterey Bay, NVIDIA was showing of Absolute Systems' GeForce GTX 980 SLI-powered system, running the aforementioned Acer 4K G-SYNC monitor, running Crysis 3.
A different look at the Absolute Systems PC.
Close up, the Acer 4K G-SYNC monitor is truly gorgeous. Look out for a review here on TweakTown of it in the near future.
The bad boys in question, two NVIDIA GeForce GTX 980 GPUs in SLI.
NVIDIA has officially launched its Maxwell-based GeForce GTX 900 series, with ZOTAC out of the gate with a bunch of new GTX 980 and GTX 970 GPUs. First off, we have three versions of each: Standard, AMP! Omega, and AMP! Extreme.
Starting with the ZOTAC GeForce GTX 980 Standard, we have the stock Core and Boost Clocks of 1126MHz and 1216MHz, respectively. The 4GB of GDDR5 RAM is clocked at 7010MHz, with the reference cooler, and the usual three DisplayPort outputs, one HDMI 2.0 and dual-link DVI port. Moving onto the AMP! Omega edition, which cranks the Core Clock to 1202MHz, and Boost to 1304MHz.
We have the Memory clock up to 7046MHz, the same 4GB of GDDR5, identical display outputs, but the "Dual-fan IceStorm" cooler. Finally, the AMP! Extreme which doesn't have Core, Boost or Memory Clock speeds revealed yet, but we do know it comes with a sexy-sounding "Triple-fan IceStorm" cooler, so expect the clocks on this GPU to be much higher. All three cards have the same number of CUDA cores, sitting at 2048.
Manli has announced its new Maxwell-based NVIDIA GeForce GTX 980 and GTX 970 GPUs, both rocking a reference cooler, with a third offering a cooling design by Manli for its GTX 970.
Starting with the Manli GeForce GTX 980 which is powered by NVIDIA's GM204 Maxwell-based GPU, which has a TDP of 178W, up from the stock 165W on NVIDIA's reference GTX 980. We have a 2048 CUDA cores, 4GB of GDDR5 RAM on a 256-bit memory bus, a Core Clock of 1126MHz, Base Boost Clock of up to 1216MHz, and 7010MHz Memory Clock. For display connectivity, the Manli GTX 980 has three DisplayPort outputs, a single HDMI 2.0 out, and two DVI outputs.
Moving onto the GTX 970, we have two models: the reference GTX 970 and then the aftermarket design. The reference card features 1164 CUDA cores, 4GB of GDDR5 RAM on a 256-bit memory bus, a Core Clock of 1050MHz, Boost Clock of 1178MHz, and 7010MHz on the memory, the same as the GTX 980. When it comes to the display connectivity, we have the same ports as the GTX 980: three DisplayPort outputs, one HDMI 2.0 and two DVI ports.
Manli has also provided a slightly modified GTX 970 with an aftermarket cooler, something that comes with slightly increased Base and Boost Clocks. We have 1076MHz, up from 1050MHz for Base, and 1216MHz up from 1178MHz for the Boost Clock. The Memory Clock remains the same: 7010MHz. These cards should be available right now in select markets.
NVIDIA Editor's Day 2014 - Another interesting technology unveiled by NVIDIA in Monterey Bay was MFAA, a new anti-aliasing technique that isn't as harsh on your hardware.
MFAA stands for Multi-Frame Sampled AA, where NVIDIA finds more information inside of every pixel on your screen, anti-aliasing the scene much better. It has the performance hit of 2x MSAA, but the look of 4x MSAA, which will provide gamers with a better looking image, without the performance hit they're used to with traditional AA methods, like MSAA.
NVIDIA Editor's Day 2014 - One of the more interesting things shown off by NVIDIA at its Editors Day was DSR, or Dynamic Super Resolution. DSR is capable of rendering a 4K image, and then downsampling it to 1080p, which has multiple use cases.
First, you can render at 4K, and then display this higher resolution image on your not-so-high resolution display, such as a 1080p panel. This provides a sharper image, without you needing to upgrade your display.
Above, we have the normal image on the left, with DSR on the right.
NVIDIA Editor's Day 2014 - One area of NVIDIA's new direction with Maxwell is virtual reality, with a totally new focus on VR with something NVIDIA calls VR Direct. VR Direct provides multiple technologies from the Maxwell architecture, and previous technologies from NVIDIA, to make the VR experience much better.
First, we have low-latency, which will reduce the amount of time it takes for the scene to be rendered on your PC, and displayed to the VR display sitting just an inch or so from your eyes. Second, we have VR SLI: something that will help your GeForce GTX SLI setup render the two scenes (one to each eye) much better, resulting in improved performance and better yet, scaling between your GPUs.
Latency is something NVIDIA is very concerned about, with the company wanting to remove as much of it as possible, in order to get a better VR gaming experience. As you can see, right now we have around 50ms of delay between the image being rendered and outputted to something like the Oculus Rift, but NVIDIA have some new technologies to remove much of this delay.
MFAA also makes an appearance, which will provide yet another layer of improved visuals. Auto Asynchronous Wrap begins doing work on the scene before the next frame, as you can see in the image above. The dotted line is where the next frame begins, but the GPU can now shift some of that ms delay (to before the frame), instead of after - resulting in delay to your eyes.
VR DSR is going to be the big thing here, with Dynamic Super Resolution able to render the scene at 3840x2160, or 4K, and then down to 1080p (or 1440p on the CV1 if the rumors are correct). This will provide a better-looking image, without needing the display on the Rift needing to be 4K, just yet.
For the past week or so, we have been sitting on the information of NVIDIA's new GeForce 900 series GPUs, with the two latest cards now official: the GeForce GTX 980 (our review is right here), and GeForce GTX 970. NVIDIA is pricing the GTX 900 series very competitively, with the GeForce GTX 980 priced at $549, and the GTX 970 at only $329. These are some incredible price points considering the feature set, improved performance, additional features and reduced TDP. NVIDIA will be discontinuing the GTX 780 and GTX 770, shifting the price of the GTX 760 to just $219.
For starters, we have the new Maxwell architecture, which is where NVIDIA is pulling this rabbit from a hat from. NVIDIA has some serious magic from Maxwell, with the star of the show, the GTX 980, really pushing the boundaries of what is possible from a GPU, without requiring a nuclear reactor to power it. For starters, the "GM204" has 5.2 billion transistors, 2048 CUDA cores, 128 Texture Units, 64 ROPS, and a 256-bit wide memory bus with 4GB of GDDR5.
NVIDIA has achieved this huge jump over the GK104 thanks to twice the performance of the GK104 with the GM204, and two times the performance-per-watt over GK104, too. There's an improved schedular, new datapath organization, and over 40% delivered performance per CUDA core on GM204. The memory architecture behind Maxwell has also received an injection of improvement, with enhanced compression algorithms, and enhancing caching effectiveness, and when compared against the GTX 680, we have some big improvements.
It looks like we are just days away from meeting the new GeForce GTX 900 series from NVIDIA, with a very detailed look at MSI's offering of the GTX 970 GAMING card, which features the company's TwinFrozr V cooler.
MSI's GTX 970 GAMING features TwinFrozr V, which includes two 100mm propeller-blade fans, with a beautiful black-and-red design. The GeForce GTX 970 itself features 1664 CUDA cores, with MSI's factory-overclocked 1140MHz and Boost clock of 1279MHz. 4GB of RAM is on the card with a 256-bit memory bus, with a TDP of just 148W. MSI requires one 8-pin and one 6-pin, which is up from the two 6-pin PCIe power connector requirements of the reference GeForce GTX 970.
One of the weird things that MSI has done to its GTX 970 GAMING card, is remove some of the DisplayPort outputs that the reference GTX 970 sports. The reference GTX 970 and GTX 980 GPUs include three DisplayPort outputs, but the MSI GTX 970 GAMING has just one DisplayPort, one HDMI and two DVI ports.
