NVIDIA GeForce GT 645 OEM

NVIDIA GeForce GT 645 OEM Image NVIDIA GF114 Image
The GeForce GT 645 OEM was a graphics card by NVIDIA, launched in April 2012. Built on the 40 nm process, and based on the GF114 graphics processor, the card supports DirectX 11.0. The GF114 graphics processor is a large chip with a die area of 332 mm² and 1,950 million transistors. Unlike the fully unlocked GeForce GTX 560 Ti, which uses the same GPU but has all 384 shaders enabled, NVIDIA has disabled some shading units on the GeForce GT 645 OEM to reach the product's target shader count. It features 288 shading units, 48 texture mapping units and 24 ROPs. NVIDIA has placed 1,024 MB GDDR5 memory on the card, which are connected using a 192-bit memory interface. The GPU is operating at a frequency of 776 MHz, memory is running at 957 MHz.
We recommend the NVIDIA GeForce GT 645 OEM for gaming with highest details at resolutions up to, and including, 1280x720.
Being a dual-slot card, its power draw is rated at 102 W maximum. Display outputs include: 2x DVI, 1x mini-HDMI. GeForce GT 645 OEM is connected to the rest of the system using a PCIe 2.0 x16 interface. The card measures 210 mm in length, and features a dual-slot cooling solution.
