Going to be honest, every time there is a new socket and new generation there is a lot of hype about it. People talking about ~30% performance uplifts, half power consumption, etc.

Sometimes there are dramatic uplifts. The 3000 series were a substantial uplift from 2000 series. The 5800x3D really is a godlike chip that performs in games roughly the same as a 7600x, and sometimes beats it.

But most of the time it's a steady 5-7% uplift of IPC and 5-7% clock speed improvement, leading to about a 10-15% uplift over previous generation. Sometimes we get a surprise but it's rare.
