Interesting. So You need more RAM ? To do more MP/s ? like 1900 or above ? Seem like at 1919 it was around 35 % which is good right ? I am guessing ? Or is there any other CPU limit that We need to be aware of. Once again thank you so much @bp2008 for testing this really appricieate it. I will need to build a new PC soon so Want to see if I Should go with AMD Or stick with intel or wait a while.. Like I can probaly stick another couple of months or may be more.. if something better is on horizon since I will be pushing 1500 + mp/s load.
My 1919 MP/s test that reached 35% CPU load was with the GUI open on a 4K monitor, with the live preview frame rate unrestricted. It was actually 19% CPU with the GUI closed.
So at this point I am pretty sure you could get to the same MP/s load on a 3700X or similar CPU with only 8 cores (If using the same or better memory speed/configuration). An i9-9900K from Intel should also do fine, and offer Quick Sync, but it would cost more and might not end up actually being more energy-efficient.
