NVIDIA has introduced two new high-end devices based on its Maxwell architecture, the GeForce GTX 980 and GeForce GTX 970.
The official pricing for GTX 980 and GTX 970 cards are Rs. 46,000 and Rs. 28,000 respectively.
Both devices have improved graphics capabilities and are more energy efficient than the previous generaton GPU’s.

Maxwell is company’s 10th generation GPU architecture, following Kepler. The new GPU’s enhances the lighting and graphics in visual computing.
The new GPU’s for the first time will deliver real-time dynamic global illumination using the new Voxel Global Illumination (VXGI) technology.
It offers a range of new technologies such as multi-frame sampled anti-aliasing (MFAA), dynamic super resolution(DSR), VR Direct and energy-efficient.
The new GPUs also deliver new features for gamers who use 4K screens and virtual reality headsets.

VXGI- Voxel Global Illumination
This feature provides realistic lighting in the games. Maxwell combines performance and programmability required to model both direct and indirect light sources.
VXGI is being added to NVIDIA GameWorks, the advanced game graphics library.
MFAA- Multi Frame Sampled Anti Aliasing
To boost the performance of new GPU’s NVIDIA has developed a new technique called multi-frame sampled anti aliasing which varies the anti-aliasing sample patterns across pixels within both individual and multiple frames.
It uses newly developed synthesis filter to provide optimum image quality.
DSR- Dynamic Super Resolution
Dynamic Super Resolution (DSR) improves image quality by rendering games at a resolution higher than what is displayed on a user’s monitor, for example games can be rendered at 4K and downsampled to 1080p, which results in a higher quality image than rendering directly at 1080p.
DSR is automatically enabled through GeForce Experience, and NVIDIA app that optimizes game settings for quality performance.
It delivers quality performance on virtual reality devices where multiple GPU’s can be assigned.
Compatibility with VR devices including the Oculus Rift is improved, Two Maxwell graphics cards in SLI can be set so that each one renders the frames for one eye.
The NVIDIA GeForce GTX 980 and GTX 970 GPU’s are available in India from card suppliers like ASUS, Galaxy and Zotac.
