Diamond Viper V770 Ultra Video Card Review

Viper V770 Ultra Celeron Benchmarks
The Viper V770 Ultra was tested on a Celeron 466 running at 525Mhz. Most readers will remember this computer from the Celeron 466 test. Our Celeron machine came with:
BX6-v2 motherboard
2 STB Black Magic 3Dfx Card in SLI mode
Micron 256 ram PC-125
SCSI 2940 UW Card
2 SCSI 4.3 GIG IBM Ultrastar 9ES DDRS-34560
SCSI Jazz drive 1.6mb
SCSI zip drive 100mb
S3 Trio 3D AGP Card (Viper V770 is coming)
Acer IDE-40x CD ROM
Four 4" Case Fans
5 Radio Shack Blower Fans
One way cable modem
Windows 98 SE
We used Quake 2 and 3D Mark 99 as our benchmarks. All tests were ran 3 times and the average score is shown. All drivers were the latest ones from the manufacturers. The V770 Ultra was tested at it's rated speed of 150/183. We also included benchmarks from the card running at a much higher 175/200. Then we took out our copy of TNTCLK and cracked it up to 185/220. Just for comparison, we tossed in the scores from the C525's SLI Voodoo 2s which runs at 100Mhz. Vsync was turned off. No tweaks or special cfg files were used. 3D Mark 99 Max was ran at 800x600, 16 bit color, 16 bit Z-Buffer, Triple Frame Buffer.

The Viper 770 Ultra does very well against the SLI V2s, which running at 100Mhz is about the same as a Voodoo 3 running at 175Mhz. The score are very even, with no clear knock outs.
The Viper 770 Ultra does knock out the Voodoo 2 in visual quality. There's really no competition here. The Viper is just plain better looking. Running Quake 3, it's a night and day difference.
How About 32 Bit?
3dfx omitted 32 bit support when it release the Voodoo 3, citing too great a lost in performance for the gains in visual quality. While the frame rates does drop when running the V770 Ultra at 32 bit, the speed is still more than fast enough to play at all but the highest resolutions.
| 32 Bit Benchmark | V770U at 150/183 | V770U at 185/220 |
| Quake 2 Demo1 800x600 | 70.9 | 76.9 |
| Quake 2 Demo1 1024x768 | 46.5 | 50.5 |
| Quake 2 Demo1 1152x864 | 37.9 | 39.9 |
| Quake 2 Crusher 800x600 | 39.5 | 41.5 |
| Quake 2 Crusher 1024x768 | 34.8 | 36.8 |
| Quake 2 Crusher 1152x864 | 30.5 | 33.6 |
The Viper V770 Ultra is very overclockable. It runs at 185/220 with just the stock heatsink fan. We're sure we can get the core speed to 190+Mhz with the Global Win heatsink fan that was used in the V770 test.
