Description:
Based on the NVIDIA RIVA TNT Ultra chip set, Diamond's Viper V770 Ultra steals the show with phenomenal frame rates, a 183 MHz memory clock, and 32-bit rendering. Rivaling the power and performance of the 3dfx Voodoo cards, Diamond's Viper V770 Ultra is a serious contender in the battle of the 3-D accelerators. Stocking all the 3-D necessities, the Viper V770 Ultra's feature set includes alpha blending, anti-aliasing, bilinear filtering, bump mapping, environment mapping, fogging, gouraud shading, MIP mapping, stencil buffer, subpixel precision, texture mapping, transparency, trilinear filtering, and z-buffering. The card also supports hardware-assisted playback of DVD (MPEG-2) video, and ships with a nice selection of software. As the only chip currently on the market that supports 32-bit rendering, the RIVA TNT Ultra has a leg up on the competition. Its easy installation, stunning graphics, and impressive frame rates in our testing impressed us. We put the Viper V770 Ultra to work on a 333 MHz Celeron system running Windows 95 and DirectX 6.1 using the Quake II time-demo test. With optimized 32-bit color at a resolution of 800 x 600, the Viper managed 42.4 frames per second, and at 1024 x 768, the frames per second dropped to 36.2. With 16-bit color at 800 x 600, frames per second came in at 43.1, and at 1024 x 768, the Viper managed 40.7 frames per second. These figures are nowhere near Diamond's lofty claims of 100 frames per second; however, with our limited CPU speed, we took these numbers with a grain of salt. Also, our 14-inch monitor maxed out at 1024 x 768, and it's important to note that the Viper V770 Ultra can go far beyond that to resolutions of 2,048 x 1,536 with a 24-inch monitor. For Quake III, which will support 32-bit rendering, and a number of other games that are beginning to use more sophisticated graphics, you may want to check out a card like the Viper V770 Ultra. This card has everything the hard-core gamer needs for the most intense, lifelike 3-D experience. Pros:
- Only card to support 32-bit rendering
- High-resolution support
- Easy to install
- Supports most games
- 32 MB memory increases performance
Cons:
- Sacrifice in performance for increased resolutions
