The NVIDIA GeForce GT 735M is a DirectX 11 graphics card of the middle class, which has been presented in spring 2013. It is based on the Kepler architecture and manufactured by TSMC in a 28-nanometer process. The GK208 chip (384 shaders) is clocked at up to 889 MHz plus boost and has a 64 bit memory interface (DDR3). Despite the nominally higher classification, the GT 735M is therefore slower than the 128-bit version of the GT 730M.
Architecture
The GK208 is a slightly revised version of the previously Kepler chip GK107. Although both have the same number of shader units (384 ALUs), the memory interface has been cut down from 128 to 64 bits.
The GK208 supports PCIe 3.0 as well as GPU Boost 2.0. This feature can automatically overclock the card if the laptop cooling system allows it. GPU Boost 2.0 is available on any notebook with a graphics card of the 700M series.
Performance
Depending on the clock rate, the performance of the GT 735M is somewhere between the GT 640M LE and the GT 640M. In particular, the narrow memory interface limits the performance significantly. Current games (as of 2013) can thus be played fluently only in low or medium settings. In older titles, there are also reserves for higher quality levels.
Features
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 735M should be similar to the old GT 640M LE (about 20 W), as Nvidia describes the card as a "low power" model. As a result, the GPU is best suited for notebooks 13-14 inches in size or greater.
The NVIDIA GeForce GT 750M SLI is a high-end DirectX 11-compatible graphics solution for laptops, consisting of two GeForce GT 750M. Each card has a 28nm GK107 core based on the Kepler architecture. With SLI, each card usually renders a single frame (AFR mode). Therefore, it may suffer from micro stuttering in low fps ranges of 30fps. This happens because of different timespans between two frames (e.g., irregular delays between sequential frames).
Architecture
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.
Performance
Equipped with fast GDDR5 memory, the GT 750M SLI performs similar to a single GeForce GTX 675MX or GeForce GTX 770M. Depending on the game, there can be big differences here, depending on how well SLI scales in a particular case. Overall, most current games (as of 2013) can be played fluently in 1080p and (very) high settings.

Power Consumption
The power consumption of the GeForce GT 750M SLI doubles compared to a single 750M, reaching about 70 - 80 W. As a result, the Nvidia GPU is only suited for larg gaming notebooks.
