NVIDIA Unveils Full Power of Maxwell GPU Architecture
SANTA CLARA, CA – 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.
