The GeForce GTX 295 was a high-end graphics card by NVIDIA, launched in January 2009. Built on the 55 nm process, and based on the GT200B graphics processor, in its G200-400-B3 variant, the card supports DirectX 10.0. The GT200B graphics processor is a large chip with a die area of 470 mm² and 1,400 million transistors. GeForce GTX 295 combines two graphics processors to increase performance. It features 240 shading units, 80 texture mapping units and 28 ROPs per GPU. NVIDIA has placed 1,792 MB GDDR3 memory on the card, which are connected using a 448-bit memory interface per GPU (each GPU manages 896 MB). The GPU is operating at a frequency of 576 MHz, memory is running at 999 MHz.
Being a dual-slot card, the NVIDIA GeForce GTX 295 draws power from 1x 6-pin + 1x 8-pin power connectors, with power draw rated at 289 W maximum. Display outputs include: 2x DVI, 1x HDMI. GeForce GTX 295 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 500 US Dollars.

GT200B GPU Notes

PureVideo HD: VP2
VDPAU: Feature Set A

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
