The GeForce GTX 485M was a mobile graphics chip by NVIDIA, launched on January 5th, 2011. Built on the 40 nm process, and based on the GF104 graphics processor, in its N12E-GTX-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 GF104 graphics processor is a large chip with a die area of 332 mm² and 1,950 million transistors. It features 384 shading units, 64 texture mapping units, and 32 ROPs. NVIDIA has paired 2,048 MB GDDR5 memory with the GeForce GTX 485M, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 575 MHz, memory is running at 750 MHz (3 Gbps effective).
Being a mxm module card, the NVIDIA GeForce GTX 485M does not require any additional power connector, its power draw is rated at 100 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.
