The three leaked models appear to be part of the Barcelo family that is launching in early 2022. Barcelo is believed to be only Cezanne refresh that is still produced on the 7 nm nodes and features the same 15 W TDP, along with the same core counts, L3 cache memory and Vega iGPUs from the current Cezanne models.

Lucienne did bring some minor improvements, like the enhanced clock gating and +1 graphics CU compared to the Renoir APUs they replaced. Hopefully, Barcelo can bring something more than a clock bump.
