As a result, the Nvidia GPU is only suited for larg gaming notebooks. The power consumption of the GeForce GT 755M SLI doubles compared to a single 755M, reaching about 100 W. 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.
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 feature set includes support for up to 4 active displays.

Overall, most current games (as of 2013) can be played fluently in 1080p and (very) high settings. Depending on the game, there can be big differences here, depending on how well SLI scales in a particular case. Thanks to the slighly higher clocks, the GT 755M SLI is somewhat faster than the former GT 750M SLI and performs similar to a single GeForce GTX 770M or GTX 680M. This feature is available on any notebook with a graphics card of the 700M series.

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. 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 expected to be up to two times more 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. irregular delays between sequential frames).Ĭompared to the GeForce 750M, the 755M respectively 755M SLI is combined only with GDDR5 graphics memory and clocked slightly higher. This happens because of different timespans between two frames (e.g. Therefore, it may suffer from micro stuttering in low fps ranges of 30fps. With SLI, each card usually renders a single frame (AFR mode). Each card has a 28nm GK107 core based on the Kepler architecture. The NVIDIA GeForce GT 755M SLI is a high-end DirectX 11-compatible graphics solution for laptops, consisting of two GeForce GT 755M. NVIDIA GeForce GT 755M SLI ► remove from comparison
