NVIDIA GeForce GTX 860M Photo NVIDIA GK104 Photo
The GeForce GTX 860M was a graphics card by NVIDIA, launched in March 2014. Built on the 28 nm process, and based on the GK104 graphics processor, in its N15P-GX-A1 variant, the card supports DirectX 12.0. The GK104 graphics processor is an average sized chip with a die area of 294 mm² and 3,540 million transistors. Unlike the fully unlocked GeForce GTX 680 Mac Edition, which uses the same GPU but has all 1536 shaders enabled, NVIDIA has disabled some shading units on the GeForce GTX 860M to reach the product's target shader count. It features 1152 shading units, 96 texture mapping units and 16 ROPs. NVIDIA has placed 2,048 MB GDDR5 memory on the card, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 797 MHz, which can be boosted up to 915 MHz, memory is running at 1250 MHz.
Being a igp card, the NVIDIA GeForce GTX 860M does not require any additional power connector, its power draw is rated at 75 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it. GeForce GTX 860M is connected to the rest of the system using a PCI-Express 3.0 x16 interface.
