The GeForce GTX 660 Rev. 2 was a graphics card by NVIDIA, launched on September 13th, 2014. Built on the 28 nm process, and based on the GK104 graphics processor, 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 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 660 Rev. 2 to reach the product's target shader count. 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 Rev. 2, 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 (6 Gbps effective).
Being a dual-slot card, the NVIDIA GeForce GTX 660 Rev. 2 draws power from 1x 6-pin power connector, with power draw rated at 140 W maximum. Display outputs include: 2x DVI, 1x HDMI 1.4a, 1x DisplayPort 1.2. GeForce GTX 660 Rev. 2 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.
