Notable members of the Stealth family have been the Diamond Stealth 3D 2000, by far the most popular S3 Virge-based board. The Diamond Stealth32, using the Tseng Labs ET4000/W32p chipset, was capable of impressive price/performance, especially in DOS. The Diamond Stealth64 Graphics 2001, with the ARK 2000PV/MT chipset, was known for excellent DOS performance at the time. The Diamond Stealth II S220, using the Rendition Verite V2100 2D/3D accelerator, was popular with enthusiasts for its excellent price/performance for both 2D and 3D gaming. A special BIOS patch was released by Diamond for the Stealth II S220 which brought its clock speed up to the same level as the high-end Verite V2200 chip, resulting in equal performance at a significantly lower price.
