ATI 3D Rage II+ DVD Image ATI Mach64 GTB Image
The 3D Rage II+ DVD was a graphics card by ATI, launched in September 1996. Built on the 500 nm process, and based on the Mach64 GTB graphics processor, in its 3D Rage II DVD variant, the card supports DirectX 5.0. The Mach64 GTB graphics processor is a relatively small chip with a die area of only 90 mm² and 5 million transistors. It features 1 pixel shaders and 0 vertex shaders, 1 texture mapping units and 1 ROPs. Due to the lack of unified shaders you will not be able to run recent games at all (which require unified shader/DX10+ support). ATI has placed 4 MB SDR memory on the card, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 60 MHz, memory is running at 83 MHz.
Being a single-slot card, its power draw is not exactly known. Display outputs include: 1x S-Video, 1x DB13W3. 3D Rage II+ DVD is connected to the rest of the system using a PCI interface.
