CPU optimized package clarification

[Rocky-IV4]

Hello
General Knowledge Question

For Intel specific Haswell hardware should I edit PKGBUILD as option # 41. Generic-x86-64-v3 (GENERIC_CPU3) (NEW) or is it better to choose # 25. Intel Haswell (MHASWELL) (NEW)

Thanks

Hello, if your cpu is Core2 series and i3/i5/i7 series chips, use option # 25. Intel Haswell (MHASWELL) (NEW),

And if it's Pentium/Celeron, use option # 41. Generic-x86-64-v3 (GENERIC_CPU3) (NEW).

Because many Pentium/Celeron chips lack the full requisite instruction sets to make use of the CPU-specific optimized packages.
