Regarding AVX, this isn't Haswell-E/Broadwell-E "issue", but Haswell-E/Broadwell-E Xeon E5 v3/v4 thing, apparently because of their tighter thermal design (see the picture I attached from Intel presentation). It's about 300Mhz difference in turbo-bin depending on individual chip, I couldn't find where Intel actually lists this info.
But it doesn't do any kind of havoc, this is just one of those 'potential' losses, these CPUS are still fast as f*** :- ). Like....really nice.
You mean that Turbo Boost can't boost from nominal base frequency or it will lower уму base frequency down? If I have 2699 v4 with 2.2GHz (2.8 all cores with TurboBoost) I will end up with 1.9GHz lowered CPU in Corona? Or it will boost it to 2.5 only (2.8GHz -300MHz)?
I wrote that Corona (and also Vray from 3.3 service pack) works 100perc. with processor groups :- ).
I also wrote it many times, maru did, ryuu did, yet people still have doubts ;)
Sorry... I got it now. Great, but not for AVX.
