The GeForce GTX 775M Mac Edition was a mobile graphics chip by NVIDIA, launched on November 8th, 2013. Built on the 28 nm process, and based on the GK104 graphics processor, in its N13E-GTX-A2 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 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, which uses the same GPU but has all 1536 shaders enabled, NVIDIA has disabled some shading units on the GeForce GTX 775M Mac Edition to reach the product's target shader count. It features 1344 shading units, 112 texture mapping units, and 32 ROPs. NVIDIA has paired 2,048 MB GDDR5 memory with the GeForce GTX 775M Mac Edition, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 797 MHz, which can be boosted up to 797 MHz, memory is running at 1250 MHz (5 Gbps effective). Being a mxm module card, the NVIDIA GeForce GTX 775M Mac Edition 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.
