Zen 5 still clocks way higher than GPUs even with the penalties. Additionally, CPUs typically target much lower latency for operations even per-clock, which adds a ton of silicon cost for the same throughput, and especially so at high clock frequency. The difficulty with transitions that Skylake-X suffered especially from just has no equivalent on GPU; if you always stay in the transitioned-to-AVX512 state on Skylake-X, things are largely normal; GPUs just are always unconditionally in such a state, but that be awful on CPUs, as it'd make scalar-only code (not a thing on GPUs, but the main target for CPUs) unnecessarily slow. And so Intel decided that the transitions are worth the improved clocks for code not utilizing AVX-512.
