The Quadro 4000 was an enthusiast-class professional graphics card by NVIDIA, launched on November 2nd, 2010. Built on the 40 nm process, and based on the GF100 graphics processor, in its GF100-825-A3 variant, the card supports DirectX 12. The GF100 graphics processor is a large chip with a die area of 529 mm² and 3,100 million transistors. Unlike the fully unlocked GeForce GTX 480 Core 512, which uses the same GPU but has all 512 shaders enabled, NVIDIA has disabled some shading units on the Quadro 4000 to reach the product’s target shader count. It features 256 shading units, 32 texture mapping units, and 32 ROPs. NVIDIA has paired 2,048 MB GDDR5 memory with the Quadro 4000, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 475 MHz, memory is running at 702 MHz (2.8 Gbps effective).
Being a single-slot card, the NVIDIA Quadro 4000 draws power from 1x 6-pin power connector, with power draw rated at 142 W maximum. Display outputs include: 1x DVI, 2x DisplayPort. Quadro 4000 is connected to the rest of the system using a PCI-Express 2.0 x16 interface. The card measures 241 mm in length, 111 mm in width, and features a single-slot cooling solution.
