utilized the RIVA TNT and RIVA TNT2 accelerators which were evolutions of the RIVA 128. In 1999, Diamond was acquired by S3 Graphics and became primarily a supplier of products based upon their graphics accelerator chips. The Diamond Viper II Z200 was based upon the S3 Savage 2000, a supposed NVIDIA GeForce 256 killer. Unfortunately the chip itself was not fully functional and the drivers were very buggy.

This brand was originally created decades ago as just "Fire" by the design team of the professional computer graphics pioneer SPEA Software AG from Starnberg (Germany) that was acquired by Diamond in 1995. Products whilst under the hood of Diamond were: Diamond Fire GL, based on the 3Dlabs GLINT 300SX and S3 Vision968 (for 2D) chips, PCI interface Diamond Fire GL 1000, based on the 3Dlabs Permedia NT (Permedia + GLINT Delta) chips, PCI interface Diamond Fire GL 2000, based on the 3Dlabs GLINT 300SX, GLINT Delta and Avance Logic ALG2564 (for 2D) chips, PCI interface Diamond Fire GL 3000, based on the 3Dlabs GLINT 500TX, GLINT Delta and Avance Logic ALG2564 (for 2D) chips, PCI interface Diamond Fire GL 4000, based on the Mitsubishi 3DPro/2mp chipset and Cirrus Logic CL-GD5446 (for 2D) chip, PCI interface Diamond Fire GL 1000 Pro, based on 3Dlabs Permedia2 chip, PCI/AGP interface The FireGL team was bought by ATI (later AMD) in 2001 once the combined Diamond/S3 dropped out of the graphics market to form SONICblue. ATI continues the Fire GL lineup. As of September 2007, thus long after that business, Diamond was also preparing a new video card, based on the latest-generation R600 graphics core. This was the same core as used for ATI driven FireGL V8650 and V8600 cards. Diamond altered the PCB reference design and labeled their device VFX 2000 series professional workstation graphics card. It came with at least 2 GB GDDR4 memory
