NVIDIA GeForce 9800 GX2 Image NVIDIA G92 Image
The GeForce 9800 GX2 was a high-end graphics card by NVIDIA, launched in March 2008. Built on the 65 nm process, and based on the G92 graphics processor, in its G92-450-A2 variant, the card supports DirectX 10.0. The G92 graphics processor is a large chip with a die area of 324 mm² and 754 million transistors. GeForce 9800 GX2 combines two graphics processors to increase performance. It features 128 shading units, 64 texture mapping units and 16 ROPs per GPU. NVIDIA has placed 1,024 MB GDDR3 memory on the card, which are connected using a 256-bit memory interface per GPU (each GPU manages 512 MB). The GPU is operating at a frequency of 600 MHz, memory is running at 1000 MHz.
We recommend the NVIDIA GeForce 9800 GX2 for gaming with highest details at resolutions up to, and including, 1680x1050.
Being a dual-slot card, the NVIDIA GeForce 9800 GX2 draws power from 1x 6-pin + 1x 8-pin power connectors, with power draw rated at 197 W maximum. Display outputs include: 2x DVI, 1x HDMI. GeForce 9800 GX2 is connected to the rest of the system using a PCIe 2.0 x16 interface. The card measures 267 mm in length, and features a dual-slot cooling solution. Its price at launch was 599 US Dollars.
