Performance Rating

The GeForce GTX 490 was a graphics card by NVIDIA, that was never released. Built on the 40 nm process, and based on the GF100 graphics processor, in its GF100-375-A3 variant, the card supports DirectX 12. Even though it supports DirectX 12, the feature level is only 11_0, which can be problematic with newer DirectX 12 titles. The GF100 graphics processor is a large chip with a die area of 529 mm² and 3,100 million transistors. Unlike the fully unlocked GeForce GTX 480 Core 512, which uses the same GPU but has all 512 shaders enabled, NVIDIA has disabled some shading units on the GeForce GTX 490 to reach the product's target shader count. GeForce GTX 490 combines two graphics processors to increase performance. It features 480 shading units, 60 texture mapping units, and 48 ROPs, per GPU. NVIDIA has paired 3,072 MB GDDR5 memory with the GeForce GTX 490, which are connected using a 384-bit memory interface per GPU (each GPU manages 1,536 MB). The GPU is operating at a frequency of 608 MHz, memory is running at 854 MHz (3.4 Gbps effective).
