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) is also integrated in the GK104 core and 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. Furthermore, high resolution monitors of up to 3840x2160 pixels can 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. The feature set includes support for up to 4 active displays. Battlefield 4 or Thief) fluently in FullHD resolution and very high detail settings.
The GPU has enough power to run demanding games of 2013/2014 (e.g. Therefore, the 870M is just slightly slower than the GTX 680MX and the Radeon R9 M290X. The chip can access up to 6 GB of GDDR5 memory (1250 MHz, 5000 MHz effective) connected via a 192-bit interface.Ĭompared to the old GeForce GTX 770M, the GTX 870M offers significantly more performance thanks to its higher clock rate and the additional shaders. In the GTX 870M, only seven blocks are active for a total of 1344 CUDA cores and 112 TMUs. The GK104 Kepler core offers eight shader blocks, called SMX, that are clocked at the same speed as the central core. The Kepler architecture is the successor to the Fermi architecture that first appeared in laptops with the GeForce 400M series. Similar to the GTX 880M, it is based on the 28 nm GK104 chip (Kepler architecture), but features less shader cores (1344 instead of 1536) as well as smaller and slower memory (6 GB GDDR5). The NVIDIA GeForce GTX 870M is a high-end DirectX 12-compatible graphics card for laptops unveiled in March 2014.
