Does the SMBIOS profile make a difference in overall performance?

I have two questions regarding system profiles.  Atm, I am using the Macmini8,1 as my SMBIOS for my Aorus Pro/9700K setup, but I am curious if it would be better to run this as an iMac9,1 or the Macmini8,1 due to the i7 9700K.  The Macmini has the 8700K and the iMac has the 9900K.  Neither are my particular processor, but I am not sure which profile to use (or if it can even be changed).  I thought I would experiment with the iMac9,1, changing the appropriate numbers in SMBIOS etc. but the boot screen gave me a compatibility error so I had to switch it back..  Also, does it really make any difference in performance to begin with the way Mojave works with the components?  As my system is working great at the moment.

System performance used to depend on SMBIOS profile for Core2Duo/Core2Quad; it could enable/disable native CPU SpeedStep. It's not so true these days but, generally speaking, you shoud always thrive to use the SMBIOS of a model that ressembles your own system. Of course, there are always exceptions to this rule and there are numerous cases for which the SMBIOS of a completely different platform is required to, say, support a graphics card.

 

So, start with the closest SMBIOS and adjust should trouble arise. If using Macmini8,1 SMBIOS resutls in a perfectly running Hack, simply keep this.
