No… Cubase does (currently) not take full advantage of the hardware. Not if you have more that 14 cores. Never the less this CPU has so much power, so that your bottleneck(s) will be else where. I have a better Cubase performance once HyperThreading is disabled, but it’s more than sufficient if HT is enabled. Working with that power is very nice.
But if you build a new PC and you only care about Cubase, then 14 cores is the limit. If possible choose a CPU that has a high frequency (and choose a silent water cooling.) In the german forum somebody has posted his hardware https://www.steinberg.net/forums/viewtopic.php?f=217&t=152122 . That could be interesting for you, since the onboard Graphic-Chip is sufficient enough. If money is an issue, then his setup seems to be an excellent choice.
Thanks for the info! Is Cubase unstable with your CPU with hyper threading enabled? Or is it stable but just doesn’t take advantage of all of the cores? If Cubase is stable then another option for me would be to use VE Pro to host sample libraries outside of Cubase.
