since a few generations ago boosts have become so good that for many use-cases base clock don't matter that much AFIK it's basically tweaked AMD EPYC™ 9654 with much higher boost and some other changes, so that's probably where the base clock comes from some situations where the base clock might still matter: - you perfectly max out CPU utilization (no I/O, hardly cache misses, etc.) and at the same time have exactly only the thermal headroom from the spec and run it for a "long" time - you want to max optimize for watter/perf the best power efficiency is likely around the base clock (for this one because of my assumption of it being more or less a tweaked server processor, on a typical consumer desktop PC I would say likely quite a bit below the base clock)
