The GeForce GT 720M was a mobile graphics chip by NVIDIA, launched in December 2013. Built on the 28 nm process, and based on the GK208 graphics processor, in its GT 720M 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 GK208 graphics processor is a relatively small chip with a die area of only 87 mm² and 1,020 million transistors. Unlike the fully unlocked GeForce GT 630 Rev. 2, which uses the same GPU but has all 384 shaders enabled, NVIDIA has disabled some shading units on the GeForce GT 720M to reach the product's target shader count. It features 192 shading units, 16 texture mapping units, and 8 ROPs. NVIDIA has paired 2,048 MB DDR3 memory with the GeForce GT 720M, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 719 MHz, which can be boosted up to 758 MHz, memory is running at 800 MHz.
Being a mxm module card, its power draw is rated at 33 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 GT 720M is connected to the rest of the system using a PCI-Express 2.0 x8 interface.
