The Quadro K620 was a professional graphics card by NVIDIA, launched in July 2014. Built on the 28 nm process, and based on the GM107 graphics processor, in its GM107-850-A2 variant, the card supports DirectX 12. The GM107 graphics processor is an average-sized chip with a die area of 148 mm² and 1,870 million transistors. Unlike the fully unlocked GeForce GTX 750 Ti, which uses the same GPU but has all 640 shaders enabled, NVIDIA has disabled some shading units on the Quadro K620 to reach the product’s target shader count. It features 384 shading units, 24 texture mapping units, and 16 ROPs. NVIDIA has paired 2,048 MB DDR3 memory with the Quadro K620, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 1058 MHz, which can be boosted up to 1124 MHz, memory is running at 900 MHz.
Being a single-slot card, the NVIDIA Quadro K620 does not require any additional power connector, its power draw is rated at 45 W maximum. Display outputs include: 1x DVI, 1x DisplayPort. Quadro K620 is connected to the rest of the system using a PCI-Express 2.0 x16 interface. The card measures 160 mm in length, and features a single-slot cooling solution.
