Yes that's normal. Video playback is not a particularly good performance test because:Thanks Casey. All looks well when playing the video, however, this could be completely non-related (and therefore normal behaviour), but whilst that video was playing in the background via Quicktime, I was browsing the Internet/Tonymac etc, and noticed that every time I clicked a link, GFX AVG actually dipped a fair bit (as you can see on the green line). Is this normal? (screenshot attached)
The same behaviour also happens if I open notes and update my personal changelog for the changes/additions I've done to this Hack etc.
- It's a fixed time test. It doesn't make sense, for example, to finish the test in half the time. It just needs to finish on time.
- It's not particularly compute-intensive because the computation is spread out over time. iGPU only needs to decode a little bit of the file to keep the video playing in real time. IGPU does not need to decode the entire 1.2GB file as fast as possible.
- During playback, the full 1.15GHz or 1.2GHz speed of iGPU is not needed, but it's there in case it's needed.
