AWOW AK41 - Web Browsers

AWOW AK41 Mini Desktop PC – Web Browsing – Week 6

Watching Video

I looked at video playback in web browsers in Week 2 of my blog. I concluded that watching 4K videos in Chrome/Firefox with a web browser isn’t viable on the AK41, yet watching the same 4K videos in Kodi or VLC is excellent. Videos encoded with lower resolutions (like 1080p) play fine in a web browser. {By the way, a desktop machine with an i5 processor and dedicated NVIDIA graphics card can play 8K videos smoothly in Chrome/Firefox].

The AK41 provides the Intel UHD Graphics 605. I have dug a little deeper by monitoring GPU usage on the AK41 with the aid of the intel-gpu-tools package. Intel developed this tool for debugging the Intel graphics drivers, but it can also be used for monitoring purposes.

In Manjaro, install the package with the command:

$ sudo pacman -S intel-gpu-tools

The package provides intel-gpu-top and a bunch of other utilities. intel-gpu-top offers a top like summary of Intel GPU usage using perf performance counters. It shows usage of the Render/3D/0, Blitter, Video, and VideoEnhance engines.

  • 3D Render – uses regular 3D operations. This is known as rcs0;
  • Blitter – hardware acceleration of 2D operations This is known as bcs;
  • Video – this is known as vcs0;
  • VideoEnhance – this is known as vecs0.

The image below shows the output of intel-gpu-top when watching a 1080p video in Kodi.

I took a screenshot of the same 1080p video at the same point using Google Chrome.

Even though the GPU is running at a higher clock speed in Chrome, the Video engine of the GPU is not used in Chrome.  Whereas Kodi (and VLC, mpv) use that engine.
