Performance Rating
The GeForce GT 645 OEM was a graphics card by NVIDIA, launched on April 24th, 2012. Built on the 40 nm process, and based on the GF114 graphics processor, 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 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 paired 1,024 MB GDDR5 memory with the GeForce GT 645 OEM, 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 (3.8 Gbps effective).
