I was running WUs through BOINC today, using just 50% of the available resources to imitate non-SMT. The Linux scheduler does a pretty good job keeping processes on their threads, so affinity is good. Those jobs returned on 19th @38k seconds were partly already running with 16 threads, before switching to 8. Those returning on 20th should last ~36k seconds.
When you were running the GW Search AVX tasks, did you have your CPU frequency set to 3.6 GHz?
I want to see how the R7 compares to an 8-core 5960x with AVX load at the same clock frequency. Running 16-threads at 3.6 GHz on my 5960x, my GW tasks were completing in the range of 48K-49K seconds each.

yes, 3,6GHz...
