NVIDIA GeForce GT 745M

The NVIDIA GeForce GT 745M is a DirectX 11 graphics card of the middle class. It is based on the Kepler architecture and manufactured by TSMC in a 28-nanometer process. The GK107 chip (384 shaders) is clocked at up to 837 MHz plus boost and has a 128 bit memory interface (usually DDR3, but GDDR5 also possible).


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. Although more shader cores are available in the Kepler architecture as compared to the Fermi design, the Kepler shaders are expected to be up to two times more power efficient. 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, even though Fermi shaders are clocked at twice the speed.

PCIe 3.0 is now supported by the mobile Kepler series and GPU Boost 2.0 can automatically overclock the card if the laptop cooling system allows it. This feature is available on any notebook with a graphics card of the 700M series.


Depending on clock speed and memory configuration, the GT 745M performs just below the GT 650M or GTX 660M. Models with GDDR5 memory are usually slightly faster than models with DDR3. Current games (as of 2013) can be played fluently in medium to high settings. In older titles, there are also reserves for additional quality features like AA and AF.


The feature set includes support for up to 4 active displays. Furthermore, high resolution monitors of up to 3840x2160 pixels can now be connected using DisplayPort 1.2 or HDMI 1.4a if available. HD-Audio codecs, such as Dolby TrueHD and DTS-HD, can be transmitted via bitstream mode through the HDMI port. However, as most laptops will feature Optimus, the integrated GPU will likely have direct control over the display ports and may limit the feature set available by the Nvidia Kepler cards.

The 5th generation PureVideo HD video processor (VP5) (also integrated in the GK107 core) offers hardware decoding of HD videos. Common codecs such as MPEG-1/2, MPEG-4 ASP, H.264 and VC1/WMV9 are fully supported up to 4K resolutions while VC1 and MPEG-4 are supported up to 1080p. Two streams can be decoded in parallel for features such as Picture-in-Picture. Another feature is the inclusion of a dedicated video encoding engine similar to Intel QuickSync that can be accessed via the NVENCI API.

Power Consumption

The power consumption of the GeForce GT 745M should be similar to the GT 645M (about 25 - 30 watts). As a result, the Nvidia GPU is best suited for multimedia notebooks 14-inches in size or greater.
