Performance Rating

The GeForce GTX 680M was a mobile graphics chip by NVIDIA, launched on June 4th, 2012. Built on the 28 nm process, and based on the GK104 graphics processor, in its N13E-GTX-A2 variant, the chip 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 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, 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 paired 4 GB GDDR5 memory with the GeForce GTX 680M, 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 758 MHz, memory is running at 900 MHz (3.6 Gbps effective).
