Performance Rating

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 GK106S 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 GK106S 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 650 Ti, which uses the same GPU but has all 768 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).
