The power consumption of the GeForce GT 740M should be similar to the GT 730M. Another feature is the inclusion of a dedicated video encoding engine similar to Intel QuickSync that can be accessed via the NVENCI API. Two streams can be decoded in parallel for features such as Picture-in-Picture. 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. The 5th generation PureVideo HD video processor (VP5) (also integrated in the GK107 core) offers hardware decoding of HD videos. 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. 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. This includes support for up to 4 active displays. The feature set of the GT 740M corresponds to the GT 730M. Detailed benchmarks can be found further down on this page. Still, the performance depends on the core clock and the GPU Boost 2.0.
The GK208 version, however, performs significantly worse and is sometimes even below the GT 640M. In older titles, there are also reserves for additional quality features like AA and AF. Current games (as of 2013) can thus be played in medium to high settings. Our benchmarks with a GK107 version show a performance just 10 percent below the GT 650M. The gaming performance of the GeForce GT 740M depends on the used chip.

PCIe 3.0 is now supported by the mobile Kepler series and an optional Turbo mode 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. 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. Although more shader cores are available in the Kepler architecture as compared to the Fermi design, the Kepler shaders are much more efficient. Both versions usually use DDR3 memory however, GDDR5 versions are possible, too.īoth GK107 and GK208 are based on the Kepler architecture and offer two shader blocks, called SMX, each with 192 shaders for a total of 384 shader cores. The shaders are clocked at the same speed as the rest of the chip.

In addition to an older version with the GK107 chip (384 shader, 810 - 895 MHz, 128 bit memory), there also exist models with the new GK208 (384 shader, up to 980 MHz plus boost, 64 bit memory). It is based on the Kepler architecture and manufactured by TSMC in a 28-nanometer process.
