.
With pinned variant I got slightly better throughput with all 5 parts of device enabled but need to repeat to be sure.
After that I'll try 3 pinned CPU threads + GPU (GPU pinned by default).

Repeated - same result. With each thread pinned to own CPU (instead of letting Windows chose) full-busy Trinity APU gives best so far results though enabling GPU gives just diminishing improve. W/o affinity management GPU enabling with full-loaded CPU decreased overall throughput.

Running on 3 CPU cores whilst using GPU should give best throughput.

Yes, I received first bench results - so far 3 [b]pinned[b] CPU processes and 1 GPU (pinned to another left CPU) provide biggest throughput.
Now need to repeat it and check 2 pinnned CPU (PC) + GPU (G) and then 2PC+2G config.
Aftr finishing this experiment I post updated picture for Trinity APU.

Unfortunately, repeated run showed just same throughput as for 4CPU only.
Big deviation here.and it's in CPU part. CPU throughput this time was less than just for 2 CPU active.
