The GeForce GTX 660 was a performance-segment graphics card by NVIDIA, launched in September 2012. Built on the 28 nm process, and based on the GK106 graphics processor, in its GK106-400-A1 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 GK106 graphics processor is an average sized chip with a die area of 221 mm² and 2,540 million transistors. It features 960 shading units, 80 texture mapping units, and 24 ROPs, . NVIDIA has paired 2,048 MB GDDR5 memory with the GeForce GTX 660, which are connected using a 192-bit memory interface. The GPU is operating at a frequency of 980 MHz, which can be boosted up to 1032 MHz, memory is running at 1502 MHz.
Being a dual-slot card, the NVIDIA GeForce GTX 660 draws power from 1x 6-pin power connector, with power draw rated at 140 W maximum. Display outputs include: 2x DVI, 1x HDMI, 1x DisplayPort. GeForce GTX 660 is connected to the rest of the system using a PCI-Express 3.0 x16 interface. The card measures 241 mm in length, and features a dual-slot cooling solution. Its price at launch was 229 US Dollars.
