Is D54250WYK really capable for 4K videos?

4K is a new buzz-word at CES 2014. I believe, HD5000 was promoted as a 4K-capable solution so I've gave it a try. It worth mentioning that there are no 4K monitors around so all the experiements were accomplished on a regular FullHD monitor and 4K video was downscaled to fit 1080p during playback.

 

MPC-HC was choosen as a player due to its wide spread -- it's got bundled with various codec packs -- and its on-screen playback statistics. See screenshots attached.

 

Sample videos came from (credits to their authors):

  1. 4K Test Sequences | Elemental Technologies -- Coastguard Pro Res, last in the list of samples -- MPEG-4 QuickTime, 602 Mbps, 3 840 x 2 160 pixels, 23.976 fps
  2. 4K Resolution Original Digital cinema 4K 4096×2304 [QFHD 3840x2160] DEMO ULTRA HD - YouTube -- grabbed 4K video and played locally -- AVC High@L5.1, 17.6 Mbps, 4 096 x 2 304 pixels, 25.000 fps

 

So... As on-screen statistics in attachments shows, neither 4K sample was played in a default framerate, frames were severely dropped -- 9/23.976 and 17/25! QT sample was not hardware accelerated, AVC sample was accelerated with DXVA2. Moreover, both times CPU was working hard showing its load between 48% and 60%. Fan was rotating at speeds between 5000 rpms and 6200 rpms. CPU temperatures were around 70C.

 

To me, everything indicates against the comfortable 4K playback with i5-4250U in my current system setup.

 

Intel, would you advise something? What codec/player should I use for a frame-to-frame 4K playback without boiling NUC in its tiny box?

 

Any feedback is highly appreciated!
