The Odroid-C2 results appear essentially unchanged for armv7
(with some minor regressions within noise) and only little
better for armv8 (but still likely within noise). On the
Raspberry Pi 4, there appears to be some improvement for
armv7 and a decent improvement for armv8 but there is higher
level of noise than on Odroid-C2. Results from this single
run are not very conclusive but we expect to see a clear
trend in the data after submission.
