The line later included chipsets with combined 2D and 3D capabilities. Initially the Stealth line was Diamond's high-end brand but transitioned to midrange after the Viper line was introduced. 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. In the middle of the Stealth line-up, Diamond chose to implement a numbering scheme to differentiate their cards. For example, the Diamond Stealth Video VRAM was rechristened the Diamond Stealth Video 3xxx. The numbers had more than a random meaning. Specifically, they tell the buyer the card's memory amount and type. The Stealth Video 3240 uses VRAM (3), is equipped with 2MB initially (2), and is upgradeable to 4MB (4). If the first digit was (2), then the card used standard DRAM. The numbering scheme confused many people since Diamond just renamed current cards with new names. The Stealth Video 3240 was simply the old Stealth Video VRAM. New cards did also use the scheme, however, such as the S3 Trio64V+ cards.
