The GeForce GT 445M was a mobile graphics chip by NVIDIA, launched on September 3rd, 2010. Built on the 40 nm process, and based on the GF106 graphics processor, in its N11E-GE-A1 variant, the chip 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 GF106 graphics processor is an average sized chip with a die area of 238 mm² and 1,170 million transistors. Unlike the fully unlocked GeForce GTS 450, which uses the same GPU but has all 192 shaders enabled, NVIDIA has disabled some shading units on the GeForce GT 445M to reach the product's target shader count. It features 144 shading units, 24 texture mapping units, and 16 ROPs. NVIDIA has paired 1,024 MB GDDR5 memory with the GeForce GT 445M, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 570 MHz, memory is running at 625 MHz (2.5 Gbps effective).
Its power draw is rated at 35 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it. Rather it is intended for use in laptop/notebooks and will use the output of the host mobile device. GeForce GT 445M is connected to the rest of the system using a PCI-Express 2.0 x16 interface.
