I was unaware of so many tests; thanks for details!  Guess you meant 
14900K (typographical error).

What about lbench (multithreaded nbench replacement) on UNIX/GNU/Linux (I 
also saw other tests available like Phoronix)?  Those OS will be used.
    So, random access memory (RAM) may affect test speeds.  Maybe 
relevant: AMD Ryzen 9 5950X central processing unit (CPU) is already on 
this BioStar X470GTA system-board with RAM overclocked '3200' (PC3200?) 
and--if possible--I'd use Intel Core i9 14900K CPU on SuperMicro X13SAE-F 
system-board, which SuperMicro technical support hasn't been clear if 
14900K (14th generation but X13SAE-F webpage says up to 13th generation) 
or faster DDR5SDRAM even works (with BIOS update unless too many Watts) or 
I should wait for possible new version/similar system-board by them, so 
maybe no way to know maximum DDR5 speed yet...
    My family has older 2016 personal computer (PC) local PC shop and I 
built... randomly crashes/halts/reboots maybe once/week, so wondering if I 
should replace BioStar with SuperMicro or if 14900K will be slower for my 
usage, in contrast to 5950X, so should be my family's new one instead 
(otherwise they get BioStar... so far very rarely crashing/halting).  They 
don't computer program nor are power users, so don't want fastest/brand-
new, but we use cores they don't, on average, and at night, number-
crunching ( http://boinc.berkeley.edu , cryptocurrency)... we both use 
plain PCI slots and sometimes (number-crunching) extra display/video/
graphics cards so these are reasons for X13SAE-F or full-/extended-ATX, 
even for them.
