The Quadro 4100 was a professional graphics card by NVIDIA. Built on the 28 nm process, and based on the GK104 graphics processor, the card supports DirectX 12. 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 Quadro 4100 to reach the product's target shader count. It features 1344 shading units, 112 texture mapping units, and 32 ROPs. NVIDIA has paired 2,048 MB DDR3 memory with the Quadro 4100, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 797 MHz, memory is running at 891 MHz. Being a single-slot card, its power draw is rated at 35 W maximum. Display outputs include: 4x mini-DisplayPort 1.2. Quadro 4100 is connected to the rest of the system using a PCI-Express 3.0 x16 interface. The card measures 160 mm in length, and features a single-slot cooling solution.
