Performance Rating

The GeForce GTX 660M was a mobile graphics chip by NVIDIA, launched on March 22nd, 2012. Built on the 28 nm process, and based on the GK107 graphics processor, in its N13E-GE-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 GK107 graphics processor is an average sized chip with a die area of 118 mm² and 1,270 million transistors. It features 384 shading units, 32 texture mapping units, and 16 ROPs. NVIDIA has paired 2,048 MB GDDR5 memory with the GeForce GTX 660M, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 835 MHz, which can be boosted up to 950 MHz, memory is running at 1250 MHz (5 Gbps effective).
