Earlier quoted context omitted.
OP is implying the i5 was Pareto-optimal in terms of price and performance.
Exactly. In 2020 the 10400f was about 40% more expensive; now Intel is forced to lower the price of their entire lineup to compete against AMD. These days, at most performance tiers, Intel+mobo combo are slightly cheaper than AMD's equivalent. Of course, Intel's CPUs have less PCIE lanes, no ECC support, lessor upgrade path, generates more heat, etc. Finally my old desktop was Intel and I am working on a lot of kerne…
What? Aside from edge-cases resulting from slightly divergent microcode implementations you should not be dealing with that. They are both x86-64. (Forgive me if I am missing an elephant in the room.)
