The 7600X did average 19 W higher in Phoronix's benchmark but that's certainly not the explanation for the 45% performance gain and benchmarks matching the 9x00X parts to the wattage levels of the 7x00X parts don't show perf/watt improvements, though it is nice to see saner default limits rather than eking that last 5% of perf instead. 82.9% in two generations/4 years is decent but few are disappointed with the performance gains of getting off Zen 3, they're disappointed with the performance gains of Zen 5 itself.
