Today is the big launch day of NVIDIA's new Maxwell-based GeForce GTX 980 and GeForce GTX 970 graphics cards! Based on a 28nm Maxwell GM204 GPU, which is the successor to the GK104, it seems this chip has no problem taking on the GK110 that powers NVIDIA's GeForce GTX 780 Ti!

The GeForce GTX 980 is made up of 5.2 billion transistors, it has 16 SMM units and 64 ROPs with a total of 2048 CUDA cores. It features a 256-bit memory bus with 4GB GDDR5 memory clocked at 7GHz and has a 1126MHz core clockspeed with 1216MHz Boost. The TDP of this card is just 165W, a figure that really highlights the energy efficiency gains made by NVIDIA.

The GeForce GTX 970 on the other hand has 13 SMM units, resulting in a total of 1664 CUDA cores. This card also has 4GB GDDR5 memory clocked at 7GHz and features a 1050MHz core with 1178MHz Boost. The TDP of this card comes in at 145W.

NVIDIA says the cards should be available total, pricing is $549 (550EUR) for the GTX 980 and $329 (325EUR) for the GTX 970.

When we take a look at some of the reviews that hit the web early this morning we can see that the GM204 is quite the wonder. Contrary to expectations, the chip manages to beat the GeForce GTX 780 Ti in all benchmarks by a margin of up to 9 percent! The GeForce GTX 980 uses roughly 70W less in load than a GeForce GTX 780 Ti and delivers roughly twice the performance per Watt than AMD's Radeon R9 290X. The large difference in power consumption also means that the GeForce GTX 980 requires less cooling and produces significantly less fan noise than AMD's top card.

The GeForce GTX 970 is just as interesting as its faster brother, the performance of this card is able to challenge a Radeon R9 290X. A quick check on Newegg reveals the cheapest Radeon R9 290 costs $40 more than a GeForce GTX 970. This means AMD will have to drop prices hard to make its Radeon R9 series attractive again, at present there's little reason to pick a R9 290 or even R9 290X over the GeForce GTX 970 as the latter one is cheaper, consumes a lot less power and runs much more silent.

NVIDIA GeForce GTX 980
In a major leap forward for gaming, NVIDIA (NASDAQ: NVDA) today introduced the first high-end products based on its Maxwell™ chip architecture -- the new GeForce® GTX™ 980 and 970 GPUs -- delivering unmatched performance, major new graphics capabilities and twice the energy efficiency of the previous generation.

Maxwell is the company's 10th-generation GPU architecture, following Kepler™. The engine of next-generation gaming, it solves some of the most complex lighting and graphics challenges in visual computing.

Its new Voxel Global Illumination (VXGI) technology enables gaming GPUs for the first time to deliver real-time dynamic global illumination. Scenes are significantly more lifelike as light interacts realistically in the game environment -- resulting in deeper levels of immersion for gamers.

And a range of new technologies -- including multi-frame sampled antialiasing (MFAA), dynamic super resolution (DSR), VR Direct and extremely energy-efficient design -- enable Maxwell-based GTX 980 and 970 GPUs to render frames with the highest fidelity at higher clock speeds and lower power consumption than any other GPU in their class.

"Maxwell has been years in the making, inspired by our gamers, and created by the best minds in 3D graphics," said Jen-Hsun Huang, NVIDIA's co-founder and chief executive officer. "Its extraordinary performance, efficiency and technologies will empower developers to do their finest work and delight gamers worldwide."

VXGI - Voxel Global Illumination
Realistic lighting is among the most challenging problems faced in real-time graphics. Simulating both direct and indirect lighting, such as reflections for dynamic scenes, has to date been too computationally demanding for GPUs beyond those available to professionals. Game developers have been forced to use lighting tricks that compromise scene realism.

Maxwell overcomes these limitations, combining the performance and programmability required to model both direct and indirect light sources. It does so by deploying VXGI, a new NVIDIA technique to accurately depict indirect lighting, including diffuse lighting, specular lighting and reflections.

VXGI is being added to NVIDIA GameWorks™, the world's most advanced game graphics library, so developers can build future games with dynamic environments filled with rich, natural lighting and breathtaking realism. It is being integrated into popular games engines like Unreal Engine 4, and will be available to developers later this year.

"We've been on a journey for more dynamic and realistic lighting in the game industry, and VXGI is the next big step in that journey," said Halldor Fannar, chief technology officer of CCP Games. "By offering real-time, dynamic indirect lighting, VXGI is a generational leap forward."

MFAA - Multi-Frame Sampled Anti-Aliasing
NVIDIA engineers have given the GTX 980 and 970 a further performance boost with a new technique called multi-frame sampled anti-aliasing (MFAA), which leverages new capabilities in Maxwell GPUs.

MFAA varies the anti-aliasing sample patterns across pixels both within an individual frame and between multiple frames. It then uses a newly developed synthesis filter to produce the best image quality and does so faster than conventional anti-aliasing. For gamers, MFAA yields image quality approaching that of 4xMSAA at the cost of 2Xmsaa -- enabling titles to run faster while maintaining high levels of image quality.

DSR - Dynamic Super Resolution
The GeForce GTX 980 and GTX 970 GPUs can deliver a higher fidelity gaming experience even for those playing on standard 1080p displays. With Maxwell's Dynamic Super Resolution (DSR) technology, games can be rendered at 4K or other high-end resolutions and then scaled down to the native resolution on the user's display using a 13-tap Gaussian filter. The resulting image is much higher quality than simply rendering directly to 1080p.

DSR is automatically enabled through GeForce Experience™, an NVIDIA application that automatically optimizes game settings for peak performance, downloads the latest drivers, and enables game streaming and in-game action capture. Gamers can turn on DSR and enjoy high-fidelity gaming with a single click of a button -- without having to upgrade their monitor.

VR Direct
To deliver on the immersive potential of virtual reality (VR), games require high frame rates and low latency. VR Direct technology incorporates a number of new features to increase performance, lower latency and increase compatibility for VR headsets. These features include:

  • VR SLI -- provides heightened performance on virtual reality devices where multiple GPUs can be assigned a specific eye to render the stereo images faster.
  • Asynchronous Warp -- cuts latency in half and quickly adjusts images as gamers move their heads, without the need to re-render new frames.
  • Auto Stereo -- improves game compatibility for VR devices, such as Oculus Rift, and allows users to play games on select headsets that weren't originally designed for VR.

    "We built Unreal Engine 4 using NVIDIA's Kepler architecture but the GTX 980 and 970 GPUs, based on the new Maxwell architecture, are the most powerful, efficient GPUs for creating scenes of unprecedented detail across PC and VR experiences right now," said Tim Sweeney, founder and CEO at Epic Games. "Our developers are pushing the graphical high end with Maxwell GPUs."

    Availability and Pricing
    The NVIDIA GeForce GTX 980 and GTX 970 GPUs are now available from the world's leading add-in card suppliers, including ASUS, Colorful, EVGA, Gainward, Galaxy, Gigabyte, Innovision 3D, MSI, Palit, PNY and Zotac. Partner participation will vary by region. Pricing is expected to start at $549 for the GTX 980 and $329 for the GTX 970.

    The GeForce GTX 980 and 970 GPUs will also be sold in fully configured systems from leading U.S.-based system builders, including AVADirect, Cyberpower, Digital Storm, Falcon Northwest, Geekbox, IBUYPOWER, Maingear, Origin PC, Puget Systems, V3 Gaming and Velocity Micro, as well as system integrators outside North America.
