It depends on what you are running?? AMD said a 15% IPC increase,so that plus any clockspeed increase?
The problem is what if Intel pushes for tests without the mitigations?? This way AMD makes sure it is ahead of the curve.
This was the point, AMD showed their CPU's in the worst case scenario, they even showed them losing in games, however intels chips were in more favourable conditions, so AMD basically said "heres our new chips without extra stuff to make them faster, against the competitions best chips without the stuff that hinders their performance, heres some slides showing whats what, form your own opinions"
Now we all know most people with a 9900k are not applying those Intel security patches if all they do is game, everyone on Windows10 will eventually get those scheduler updates, they will boost those AMD scores between 6 and 16% im told.
Do we know what ram was being used? we have no info on PBO and XFR and if the chips can manually OC etc.. there is potentially nothing left on the table for those chips except the Win10 update to boost performance, but on the other hand there could potentially be a ton of OC headroom left untapped, we just dont know.
But we do know the new AMD stuff competes and more often than not beats Intels best in games without some additional enhancements that are easy to do
