APU & Graphics Card & Hardware:

GIGABYTE GB-BXA8-5545

  • AMD Richland A8-5545M 1.7G/ 2.7GHz(Turbo)
  • AMD Radeon HD 8510G
  • 16 GB ram (2x8)
  • 120 GB msata SSD
  • Screen Resolution: 3840x2160 @ 24hz 
  • AMD Catalyst Driver Version:
    12.105.0.0

    Operating System
    Win 7 64bit Enterprise

    Issue Details
    When trying to playback 4k video (via youtube, VLC, windows media player) the CPU is maxed out to 100% and video gets 1 frame per second or lower in windowed or fullscreen mode. Playback of a 720p in windowed mode is smooth, but 720p and 360p video contect played back fullscreen gets less than 10FPS. 

    AMD says with the A8 series I can "Take advantage of the newest 4k monitors (4096x2160)." See the ocument here: http://resources.creativechannel.com/151186/NA%202013%20HTS.pdf

    It seems I can only use this APU for spreadsheets and light web browsing @ 4k. Am I missing something?

    Do you realize that the A8-5545M is one of the lowest powered laptop APUs AMD sells and as such has considerable lower performance as it's only a 19w APU? You should expect the APU to be maxed out pretty much all the time.

    Yes, I realize that. I'm just looking for the cheapest/smallest solution that'll output 4k @ 24hz or 30hz and be smooth for video playback (no gaming).

    I also see the marketing materials that claim it supports 4k. After upgrading to the latest 14.x beta drivers I saw some drastic improvement. The thing can playback a 1080p video (while monitor at 4k resolution) smooth, and a 4k video @ 4k resolution is bearable, there's some choppines depending on the scene. This was a win7 install, I'll try with win8.1 on the GB-BXA8-5545 and see if that makes a difference.

    My requirement was a tiny form factor, hence why I went with the brix/nuc setups. I've decided to fork over the extra $250 and get a GIGABYTE GB-BXi5-4570R with i5-4570R/Iris Pro graphics 5200, as that's proven to playback 4k video smooth.

    It does support 4K but it doesn't say anything about being able to run video @ 24-30 Hz. from the second lowest powered Trinity APU. I can't imagine anyone expecting that kind of performance from a 19w APU.

    The i5-4570R is a 65w APU. That's desktop APU territory. The A10-5700 would be in that thermal range and naturally run much faster (probably double or more), than the 19w A8-5545M you selected originally.
