The Quadro K4100M was an enthusiast-class professional mobile graphics chip by NVIDIA, launched on July 23rd, 2013. Built on the 28 nm process, and based on the GK104 graphics processor, in its N15E-Q3-A2 variant, the chip supports DirectX 12. 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 Quadro K4100M to reach the product's target shader count. It features 1152 shading units, 96 texture mapping units, and 32 ROPs. NVIDIA has paired 4 GB GDDR5 memory with the Quadro K4100M, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 706 MHz, which can be boosted up to 706 MHz, memory is running at 800 MHz (3.2 Gbps effective). Being a mxm module card, the NVIDIA Quadro K4100M 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. Its price at launch was 1499 US Dollars.
