The GeForce GTX 260 was a high-end graphics card by NVIDIA, launched on June 16th, 2008. Built on the 65 nm process, and based on the GT200 graphics processor, in its G200-100-A2 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 GT200 graphics processor is a large chip with a die area of 576 mm² and 1,400 million transistors. Unlike the fully unlocked GeForce GTX 280, which uses the same GPU but has all 240 shaders enabled, NVIDIA has disabled some shading units on the GeForce GTX 260 to reach the product's target shader count. It features 192 shading units, 64 texture mapping units, and 28 ROPs. NVIDIA has paired 512 MB GDDR3 memory with the GeForce GTX 260, which are connected using a 448-bit memory interface. The GPU is operating at a frequency of 576 MHz, memory is running at 999 MHz.
