The GeForce GTX 645 OEM was a graphics card by NVIDIA, launched on April 22nd, 2013. Built on the 28 nm process, and based on the GK106 graphics processor, in its GK106-200-A1 variant, the card supports DirectX 12. Even though it supports DirectX 12, the feature level is only 11_0, which can be problematic with newer DirectX 12 titles. The GK106 graphics processor is an average sized chip with a die area of 221 mm² and 2,540 million transistors. Unlike the fully unlocked GeForce GTX 660, which uses the same GPU but has all 960 shaders enabled, NVIDIA has disabled some shading units on the GeForce GTX 645 OEM to reach the product’s target shader count. It features 576 shading units, 48 texture mapping units, and 16 ROPs. NVIDIA has paired 1,024 MB GDDR5 memory with the GeForce GTX 645 OEM, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 824 MHz, memory is running at 1000 MHz (4 Gbps effective). Being a single-slot card, the NVIDIA GeForce GTX 645 OEM does not require any additional power connector, its power draw is rated at 65 W maximum. Display outputs include: 1x DVI, 1x HDMI, 1x DisplayPort. GeForce GTX 645 OEM is connected to the rest of the system using a PCI-Express 3.0 x16 interface. The card measures 147 mm in length, and features a single-slot cooling solution. Category: Graphics Cards
