HD-Audio codecs, such as Dolby TrueHD and DTS-HD, can be transmitted via bitstream mode through the HDMI port. Furthermore, high resolution monitors of up to 3840x2160 pixels can now be connected using DisplayPort 1.2 or HDMI 1.4a if available. The improved feature set now includes support for up to 4 active displays. Older and less demanding games, such as Modern Warfare 3, are easily playable with maxed out settings and high resolutions. Therefore demanding games like Battlefield 3 are playable in 1366x768 and medium settings. The gaming performance of the GeForce GT 645M equipped with DDR3 graphics memory depends on the 3D clock in the used laptop and is slightly above an average GT 640M. The implementation of this boost mode is done in the BIOS, but it is ultimately dependent upon the manufacturer of the laptop.

PCIe 3.0 is now supported by the mobile Kepler series and an optional Turbo mode can automatically overclock the Nvidia card by a theoretical 15 percent if the laptop cooling system allows it. However, due to the missing hot clock of the shader domain, two shaders of a Kepler chip are as fast as one shader of a Fermi chip (the latter is clocked twice as fast). Although more shader cores are available in the Kepler architecture as compared to the Fermi design, the Kepler shaders are still expected to be up to twice as power efficient. The GK107 Kepler core offers two shader blocks, called SMX, each with 192 shaders for a total of 384 shader cores that are clocked at the same speed as the processor core. The Kepler architecture is the successor to the Fermi architecture that first appeared in laptops with the GeForce 400M series. The graphics card uses a 128-Bit wide memory interface with either the more common but slower DDR3 for VRAM or the more expensive and faster GDDR5. It is a faster clocked GeForce GT 640M and therefore also based on the Kepler GK107 architecture manufactured in 28nm at TSMC. The NVIDIA GeForce GT 645M is a mid-range, DirectX 11.1 compatible graphics card that was announced in the third quarter of 2012 for laptops.

This device has no display connectivity, as it is not designed to have monitors connected to it. The GPU is operating at a frequency of 837 MHz, memory is running at 900 MHz. NVIDIA has paired 2,048 MB DDR3 memory with the GeForce GT 745M, which are connected using a 128-bit memory interface. It features 384 shading units, 32 texture mapping units, and 16 ROPs. The GK107 graphics processor is an average sized chip with a die area of 118 mm² and 1,270 million transistors. Even though it supports DirectX 12, the feature level is only 11_0, which can be problematic with newer DirectX 12 titles. Built on the 28 nm process, and based on the GK107 graphics processor, in its N14P-LP variant, the chip supports DirectX 12. The GeForce GT 745M was a mobile graphics chip by NVIDIA, launched on April 1st, 2013.
