i would think a module it's 160% if it loss 20%, i think it's on 2 cores the loss.

But the advantage is single thread way much faster than tuban, i think. One core ( so one thread ) can run code on the 256bits AVX FP. It's not faster with 2 threads on one module for FP, but the advantage, is less threaded FP code will be faster.

Int should be faster too in ipc even pipe is deeper. As JF- said, PII was 1.5+1.5, BD ( ² ? ) is 2+2. ( ALU+AGU ).

I think it's a good deal. JF- said this week we are going to know what about BD work in 4 threads on 4 modules. Will be auto on 2 modules and 2 modules off or 4 modules on ?
