The GeForce GTX 285 was a performance graphics card by NVIDIA, launched in December 2008. Built on the 55 nm process, and based on the GT200B graphics processor, in its G200-350-B3 variant, the card supports DirectX 11.1. The GT200B graphics processor is a large chip with a die area of 470 mm² and 1,400 million transistors. It features 240 shading units, 80 texture mapping units and 32 ROPs. NVIDIA has placed 1,024 MB GDDR3 memory on the card, which are connected using a 512-bit memory interface. The GPU is operating at a frequency of 648 MHz, memory is running at 1242 MHz.
Being a dual-slot card, the NVIDIA GeForce GTX 285 draws power from 2x 6-pin power connectors, with power draw rated at 204 W maximum. Display outputs include: 2x DVI, 1x S-Video. GeForce GTX 285 is connected to the rest of the system using a PCI-Express 2.0 x16 interface. The card measures 267 mm in length, and features a dual-slot cooling solution. Its price at launch was 359 US Dollars.

GT200B GPU Notes

GT200B, commonly printed on the chip package as G200-xxx-Bx is an optical shrink of the G200 core to the newer 55 manufacturing process of TSMC. It helped shrink the core's energy and thermal footprints to a level that even facilitated building a dual-GPU accelerator
