NVIDIA GeForce GTX 260 OEM Image NVIDIA GT200B Image
The GeForce GTX 260 OEM was a graphics card by NVIDIA, launched in December 2009. Built on the 55 nm process, and based on the GT200B graphics processor, in its G200-103-B2 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. Unlike the fully unlocked GeForce GTX 275, which uses the same GPU but has all 240 shaders enabled, NVIDIA has disabled some shading units on the GeForce GTX 260 OEM to reach the product's target shader count. It features 192 shading units, 64 texture mapping units and 28 ROPs. NVIDIA has placed 1,792 MB GDDR3 memory on the card, which are connected using a 448-bit memory interface. The GPU is operating at a frequency of 518 MHz, memory is running at 1008 MHz.
We recommend the NVIDIA GeForce GTX 260 OEM for gaming with highest details at resolutions up to, and including, 1280x720.
Being a dual-slot card, its power draw is rated at 182 W maximum. Display outputs include: 2x DVI, 1x S-Video. GeForce GTX 260 OEM 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

Compute Capability: CUDA 1.3

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
