The GeForce GTX 285 was a performance-segment graphics card by NVIDIA, launched on December 23rd, 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. Even though it supports DirectX 11, the feature level is only 10_0, which can be problematic with many DirectX 11 & DirectX 12 titles. 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 paired 1,024 MB GDDR3 memory with the GeForce GTX 285, 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 |
