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.

    Building a reliable PC involves more than just assembling the parts. You need to be able to configure all of the BIOS settings appropriately. This can be quite involved and frustrating as it can require a lot of trial and error with stress testing. It is however often the only means to get a 100% reliable PC.

    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.
