The GeForce GTX 680MX Mac Edition was a mobile graphics chip by NVIDIA, launched on October 23rd, 2012. Built on the 28 nm process, and based on the GK104 graphics processor, in its N13E-GTX2-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. It features 1536 shading units, 128 texture mapping units, and 32 ROPs. NVIDIA has paired 2,048 MB GDDR5 memory with the GeForce GTX 680MX Mac Edition, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 719 MHz, which can be boosted up to 719 MHz, memory is running at 1250 MHz (5 Gbps effective).
Its power draw is rated at 122 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 GTX 680MX Mac Edition is connected to the rest of the system using a PCI-Express 3.0 x16 interface.
