The power consumption of the GeForce 825M 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) 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 825M corresponds to the GT 730M and 740M. Current games (as of 2013/2014) can thus be played in 1366 x 768 and medium settings. However, very demanding games such as Crysis 3 or Battlefield 4 will require lower resolutions and/or details. PCIe 3.0 is now supported by the mobile Kepler series and GPU Boost 2.0 mode can automatically overclock the card if the laptop cooling system allows it. This feature is available on any notebook with a graphics card from the 800M series.Īccording to our benchmarks, the performance of the GeForce 825M is somewhere between the GT 730M and GT 740M. Furthermore, the GK208 chip has 16 TMUs and 8 ROPs on a 64-bit memory interface. GK208 is based on the Kepler architecture and offers 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. It is based on the 28 nm Kepler architecture and uses the same GK208 chip as the GeForce GT 730M and 740M. The NVIDIA GeForce 825M (sometimes also called GT 825M) is a middle class DirectX 12 graphics card. NVIDIA GeForce 825M ► remove from comparison
