NVIDIA has announced two new graphics cards for the PC, the flagship single-GPU GTX 980 and the mid-range GTX 970. Both are based on NVIDIA's 10th generation Maxwell architecture, which succeeds Kepler.
Other than being more powerful, the two new graphics cards also introduce some new technologies from NVIDIA, including Voxel Global Illumination (VXGI), which enables real-time global illumination. This enables the light to reflect off surfaces more naturally, and the resultant illumination is more realistic and accurate.
Another new feature is Dynamic Super Resolution, which is generally known as supersampling. What this feature does is it renders the game at a higher resolution than your monitor. So if you have a 1080p monitor, the graphics card will render the game at 4K or higher and then downsample it down to fit your screen. The resultant image is cleaner and has less aliasing. This is sometimes present in games and available as SSAA or FSAA options within anti-aliasing settings but in this case, NVIDIA is doing it within its own GeForce Experience software rather than letting the game do it, assuming the game has the option.
The GTX 980 and GTX 970 will be available from various hardware partners, including ASUS, Colorful, EVGA, Gainward, Galaxy, Gigabyte, Innovision 3D, MSI, Palit, PNY and Zotac. The prices start at $549 for the GTX 980 and $329 for the GTX 970.
