No, that's literally been the case with Intel processors. Especially mobile ones. There's practically zero difference between Haswell and Whiskey Lake (5 years newer) core performance. Even Ice Lake was a minor improvement. But the power consumption has dropped, heat generation has dropped (a lot of it because they abandoned FIVR), IGP performance has increased and they started supporting DDR4, so overall performance has increased. I personally lament the death of the mobile socket. I hope AMD still has socketed mobile processors, but I doubt it. They're only useful for people who want to upgrade or fix their laptops themselves, people who want to resell their old laptop/parts, and the environment.
