Is there since information in Intel codenames I'm perhaps unaware of?
These days, CPU speed matters less than it did back then, but there still are CPU-hungry applications (I'm looking at you, Autodesk Inventor!), and if I had to put together a PC from scratch (which I think I'll actually sometime this year), I would be kind of lost.
But that does make the decision what CPU is best for a given use case and budget much more complex, too.
(Like I said, the impact of the CPU on overall system performance is less today than twenty years ago for many use cases, so it is not that much of a problem.)
