    Check dmesg for any GPU resets; the Intel i915 driver has become pregressively worse since kenel 4.18, with the 5.x series being absolutely unusable for me because of regular random softlocks on the GUI. There has been comments on Arch forums that kernel 5.6.something fixed it, but I've not found that to be the case for me with Mint 19.3. I'm still rocking 4.15.something as a result, because it was the last "easy" kernel which allowed my NUC to work without griefing me one way or another.

    I have the 9560 and haven't noticed anything weird upon upgrading to 20.04 from 19.10. But I haven't benchmarked so I don't really know for sure.

    Do you think it's related to mitigations? I have a 7390 2-in-1 running each master kernel as it's released and haven't noticed those kinds of regressions (admittedly via seat-of-the-pants feel), but I have every mitigation I can find turned "off".

    The sample Dell is a very new & physically tiny 13 inch SUBNOTEBOOK. This creates several problems.
    1) COOLING is compromised, by space volumes, channel flows, noise & battery drainage.
    2) Specialized latest hardware is small sized, power-use compromised & requires special drivers.
    3) This whole setup is optimised for Microsoft Windows
    4) Being newly released, there are the usual BIOS updates coming.
    5) Linux hardware drivers are non-existent or poor functioning.
    6) Exotic hardware demands specially written code & drivers.
    7) External fans for the subnotebook will avoid heat throttling.
    8) If performance is preferred over battery consumption, tweaks are needed.
    9) Tweaking Linux is easy: latest low latency Linux kernel.
    10) Hardware tweaks include undervolting, etc.

    Do you see any errors in `journalctl` when it "pauses"?

    Try a 4.19 kernel or 5.4.
