NVIDIA GeForce GTX 275 PhysX Edition Image NVIDIA GT200B Image
The GeForce GTX 275 PhysX Edition was a graphics card by NVIDIA, launched in February 2010. 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 PhysX Edition for gaming with highest details at resolutions up to, and including, 1680x1050.
Being a dual-slot card, the NVIDIA GeForce GTX 275 PhysX Edition draws power from 1x 6-pin + 1x 8-pin power connectors, with power draw rated at 219 W maximum. Display outputs include: 2x DVI. GeForce GTX 275 PhysX Edition 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.

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
