NVIDIA GeForce GTX 680M Image NVIDIA GK104 Image
The GeForce GTX 680M is a graphics card by NVIDIA, launched in June 2012. Built on the 28 nm process, and based on the GK104 graphics processor, in its N13E-GTX-A2 variant, the card supports DirectX 12.0. The GK104 graphics processor is an average sized chip with a die area of 294 mm² and 3,540 million transistors. Unlike the fully unlocked GeForce GTX 680 Mac Edition, which uses the same GPU but has all 1536 shaders enabled, NVIDIA has disabled some shading units on the GeForce GTX 680M to reach the product's target shader count. It features 1344 shading units, 112 texture mapping units and 32 ROPs. NVIDIA has placed 4,096 MB GDDR5 memory on the card, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 719 MHz, which can be boosted up to 719 MHz, memory is running at 900 MHz.
We recommend the NVIDIA GeForce GTX 680M for gaming with highest details at resolutions up to, and including, 1680x1050.
Being a mxm module card, the NVIDIA GeForce GTX 680M does not require any additional power connector, its power draw is rated at 100 W maximum.
