The GeForce GT 630 Rev. 2 PCIe x8 was a graphics card by NVIDIA, launched in May 2013. Built on the 28 nm process, and based on the GK208 graphics processor, in its GK208-301-A1 variant, the card supports DirectX 12.0. The GK208 graphics processor is a relatively small chip with a die area of only 87 mm² and 915 million transistors. It features 384 shading units, 32 texture mapping units and 8 ROPs. NVIDIA has placed 2,048 MB DDR3 memory on the card, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 902 MHz, memory is running at 900 MHz.
Being a single-slot card, the NVIDIA GeForce GT 630 Rev. 2 PCIe x8 does not require any additional power connector, its power draw is rated at 25 W maximum. Display outputs include: 1x DVI, 1x HDMI, 1x VGA. GeForce GT 630 Rev. 2 PCIe x8 is connected to the rest of the system using a PCI-Express 2.0 x8 interface. The card measures 115 mm in length, and features a single-slot cooling solution.
