    But LW 11.5 result is more noisy.
    Does that have GI importance sampling turned on in LW2015?

    Yes.
    Added test:

    LW 2015.3 = 18 min 2 sec
    LW 2015.3 = 14 min 0 sec - importance sampled BG = off - noisy
    LW 11.5 = 13 min 5 sec - noisy

    Rendered on:
    Threadripper 3960x (Auto Overclock in Ryzen Master software active)
    RAM 64GB @ 3200 14 14 14 34 1T
    No additional OC done.

    I've not installed the Auto Overclock Ryzan master software. That's just native CPU balancing itself.
    I'm not sure I have much headroom for overclocking on Air cooling though. Maybe I'll try.

    I've got RAM at 3200MHz with slightly slower timings than yours. 16-18-18-35. The RAM is overclocked from 2666MHz.

    I've not checked/tried with the importance sampling as off.
    Sounds like it gives noisey results like 11.5?

    Ok, minor update and history:

    i7 3930K - hex-core with HT - 4.5GHz - LW 11.5 @ 1 hour 6 mins, 3 seconds
    i7 3930K - hex-core with HT - 4.2GHz - LW 2015.3 @ 1 hour 42 mins 21 secs

    Threadripper 3960X - 24 core HT/SMT - around 4GHz - LW 2015.3 @ 19 mins 13s
    Threadripper 3960X - 24 core HT/SMT - around 4-4.1GHz - LW 2015.3, importance sampling OFF @ 14 mins 31s

    2015.3 with GI importance sampling off behaves similarly to 11.6.3 (you're using 11.6.3, not actually 11.5, right?!), producing noisier results in around the same time. With GI importance sampling on, 2015.3 does additional sampling which takes a bit longer, but produces significantly cleaner results.

    As subsequent 11.x revisions fixed a bunch of bugs over 11.5, you really should be comparing 11.6.3 not 11.5, unless intentionally avoiding a specific, known bug from later revision. Better put, unless you have a clear justification to use earlier revisions, you should always compare with the latest available for a given version.

    Actually, shame on me. I wrote 11.5 as I was thinking that was the latest version of LW 11. I can't even reember the version numbers now.

    I do know, that when I ran the benchmark in Februrary 2013, it was the current version of LW 11.x, whatever that was.
