CPUTYPE in BSD and -march in Linux tell compiler what the CPU is capable of. For instance, my desktop (Linux, Kaby Lake)
Code:
-march=broadwell -mmmx -msse -msse2 -msse3 -mssse3 -mcx16 -msahf -mmovbe -maes -mpclmul -mpopcnt -mabm -mfma -mbmi -msgx -mbmi2 -mavx -mavx2 -msse4.2 -msse4.1 -mlzcnt -mrtm -mhle -mrdrnd -mf16c -mfsgsbase -mrdseed -mprfchw -madx -mfxsr -mxsave -mxsaveopt -mclflushopt -mxsavec -mxsaves --param l1-cache-size=32 --param l1-cache-line-size=64 --param l2-cache-size=8192
By using -march=native these capabilities will be used. While using CPU intensive applications, like video encoding, it does make difference. For office applications - not so much. Everybody interested in benchmarks is free to do their own testing. Below is same from my Kodi frontend (Intel N3050) for comparison.
Code:
-march=silvermont -mmmx -msse -msse2 -msse3 -mssse3 -mcx16 -msahf -mmovbe -maes -mpclmul -mpopcnt -msse4.2 -msse4.1 -mrdrnd -mprfchw -mfxsr --param l1-cache-size=24 --param l1-cache-line-size=64 --param l2-cache-size=1024
In case of building from source I see no reason why one should not use these optimizations. Of course, resulting binaries may not run elsewhere.

Thanks for all the input. I should have known that older versions of BSD would not work with newer hardware. I did have a download of
11.1, but I did not try that version although I thought I did. Since the posting I did successfully load 11.1 to my computer. After posting
I tried OpenBSD 6.2 and GhostBSD, but neither one would boot from CDROM. Again thanks and now that I started my FreeBSD adventure I will
probably be getting back to the forum occasionally.

Congratulations!! Very glad you got that running. While there may be settings that would allow those others to load, I would stick with what you know works for a bit. Have fun!

Ever thought about changing your monicker now that you've got a BSD box, Linux Hal?

BSD Hal9000, perhaps?
