ATI FireGL V7100 Image ATI R423 Image
The FireGL V7100 was a high-end professional graphics card by ATI, launched in December 2004. Built on the 130 nm process, and based on the R423 graphics processor, in its R423 GL variant, the card supports DirectX 9.0c. The R423 graphics processor is an average sized chip with a die area of 289 mm² and 160 million transistors. It features 16 pixel shaders and 6 vertex shaders, 16 texture mapping units and 16 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 256 MB GDDR3 memory on the card, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 493 MHz, memory is running at 475 MHz.
We recommend the ATI FireGL V7100 for gaming with highest details at resolutions up to, and including, 1280x720.
Being a single-slot card, the ATI FireGL V7100 does not require any additional power connector, its power draw is rated at 91 W maximum. Display outputs include: 2x DVI, 1x S-Video. FireGL V7100 is connected to the rest of the system using a PCIe 1.0 x16 interface. The card measures 211 mm in length, and features a single-slot cooling solution. Its price at launch was 1,099 US Dollars.
