The GeForce GT 420 OEM was a graphics card by NVIDIA, launched in September 2010. Built on the 40 nm process, and based on the GF108 graphics processor, in its GF108-200-A1 variant, the card supports DirectX 12.0. The GF108 graphics processor is an average sized chip with a die area of 116 mm² and 585 million transistors. Unlike the fully unlocked GeForce GT 730, which uses the same GPU but has all 96 shaders enabled, NVIDIA has disabled some shading units on the GeForce GT 420 OEM to reach the product's target shader count. It features 48 shading units, 4 texture mapping units and 4 ROPs. NVIDIA has placed 1,024 MB DDR3 memory on the card, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 700 MHz, memory is running at 900 MHz.
Being a single-slot card, the NVIDIA GeForce GT 420 OEM does not require any additional power connector, its power draw is rated at 50 W maximum. Display outputs include: 1x DVI, 1x HDMI, 1x VGA. GeForce GT 420 OEM 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.
