NVIDIA GM107 Image
The GeForce 845M is a graphics card by NVIDIA, launched in February 2015. Built on the 28 nm process, and based on the GM107 graphics processor, in its N15S-GT1R variant, the card supports DirectX 12.0. The GM107 graphics processor is an average sized chip with a die area of 148 mm² and 1,870 million transistors. Unlike the fully unlocked GeForce GTX 750 Ti, which uses the same GPU but has all 640 shaders enabled, NVIDIA has disabled some shading units on the GeForce 845M to reach the product's target shader count. It features 512 shading units, 32 texture mapping units and 16 ROPs. NVIDIA has placed 2,048 MB DDR3 memory on the card, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 863 MHz, memory is running at 1001 MHz.
We recommend the NVIDIA GeForce 845M for gaming with highest details at resolutions up to, and including, 1280x720.
Being a igp card, its power draw is rated at 45 W maximum. GeForce 845M is connected to the rest of the system using a PCIe 3.0 x16 interface.
