The GeForce GT 640 OEM Rebrand was a graphics card by NVIDIA, launched in April 2012. Built on the 40 nm process, and based on the GF116 graphics processor, in its GF116-150-A1 variant, the card supports DirectX 12.0. The GF116 graphics processor is an average sized chip with a die area of 238 mm² and 1,170 million transistors. Unlike the fully unlocked GeForce GTX 550 Ti, which uses the same GPU but has all 192 shaders enabled, NVIDIA has disabled some shading units on the GeForce GT 640 OEM Rebrand to reach the product's target shader count. It features 144 shading units, 24 texture mapping units and 24 ROPs. NVIDIA has placed 1,536 MB DDR3 memory on the card, which are connected using a 192-bit memory interface. The GPU is operating at a frequency of 720 MHz, memory is running at 800 MHz.
Being a single-slot card, the NVIDIA GeForce GT 640 OEM Rebrand does not require any additional power connector, its power draw is rated at 75 W maximum. Display outputs include: 2x DVI, 1x mini-HDMI. GeForce GT 640 OEM Rebrand is connected to the rest of the system using a PCI-Express 2.0 x16 interface. The card measures 145 mm in length, and features a single-slot cooling solution.
