Diamond Viper
The Viper was released in 1993. The Weitek P9000 chip is a Windows accelerator, while the 5286 or OTI087X from Oak Technology handled the 2D VGA work. Some cards have the more integrated P9100 in place of both the P9000 and 5286 chips.
It's worth noting that the Viper VLB was known for its poor performance, due to its sluggish VGA chip which can only run on a 16-bit interface.

The Viper was an odd design choice in 1993, after Diamond had good success with the Stealth Pro.
The Viper's standard RAMDAC was a Brooktree Bt485 which ran at 110 MHz, though Diamond offered a Sierra HiColor DAC as a cost option for this card.
Board Revisions
Several board revisions are known to exist for the Viper: B1, B3, E3 and E4.
Competition
The Viper VLB went up against a range of early VESA Local Bus "GUI accelerators" back in 1993, including the Hercules Graphite VL (HG510), Genoa 8500 VL-20, Number Nine #95GXE VL-Bus, Orchid Fahrenheit VA/VLB, STB Horizon VL, Cardinal Warpspeed, and ATI Graphics Ultra Pro mach32. When compared to these, the Viper VLB performed the best. InfoWorld ran a benchmark comparison of all of these cards, with the Viper VLB scoring the top position with a VidMark of 86.88, though the rest of the pack weren't far behind.
Price was an important factor, and it didn't always mean you got a card that was far better just because you had deeper pockets. In second place was the Cardinal Warpspeed with a score VidMark of 84.84. In third place was the $595 Number Nine #9GXE VL-Bus with a score of 78.70. The Genoa 8500 scored third place with a VidMark of 75.89 even though it cost just $219 (under half the price of the Viper). Behind these were the Orchid Fahrenheit VA/VLB which came in fourth place with a score of 75.84 and the STB Horizon VL that scored 70.65. Interestingly, bottom of the pile was the ATI Graphics Ultra Pro mach32 with a VidMark of 61.11 despite it relatively high price tag of $499.
