NVIDIA GeForce GTX 275 Image NVIDIA GT200B Image
The GeForce GTX 275 was a performance graphics card by NVIDIA, launched in January 2009. Built on the 55 nm process, and based on the GT200B graphics processor, in its G200-105-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. It features 240 shading units, 80 texture mapping units and 28 ROPs. NVIDIA has placed 896 MB GDDR3 memory on the card, which are connected using a 448-bit memory interface. The GPU is operating at a frequency of 633 MHz, memory is running at 1134 MHz.
We recommend the NVIDIA GeForce GTX 275 for gaming with highest details at resolutions up to, and including, 1680x1050.
Being a dual-slot card, the NVIDIA GeForce GTX 275 draws power from 2x 6-pin power connectors, with power draw rated at 219 W maximum. Display outputs include: 2x DVI. GeForce GTX 275 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 249 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
