As far as I understand it the issue depends on the specific workload and which CPU is being used.
Either way, in general the test has shown year after year that relatively fast CPUs with more cores perform better. Sometimes there are differences in architecture that may change the outcome, but it’s generally true.
By the way; there’s the rumor floating around that there is an actual temporary “fix” to the MMCSS limitation in Windows for Cubase/Nuendo. I believe you have to contact Steinberg directly to get instructions on how to do it.
