Interesting - what’s the power consumption on it?

Previous gen (4800U) was 15W TDP by default (configurable between 10W and 25W).
This new one (5800U) was not yet officially announced.

Sadly, TDP is far from held on those. What you get at 15W is the base clock present at: https://www.anandtech.com/show/15324/amd-ryzen-4000-mobile-a...
For the Ryzen 7 4800U, that's just 1.8GHz. 4.2GHz which is the turbo clock blows through that limit by a lot. (of course that's for multi-core workloads)
For Ryzen 5th generation, we have this for per-core only power draw, without the I/O: https://www.anandtech.com/show/16214/amd-zen-3-ryzen-deep-di...
We can see from the graph at https://images.anandtech.com/doci/16214/PerCore-1-5950X_575p... that to reach 6.6W per core, the clock has to fall to 3.8GHz. At such a clock, Zen 3 is way behind the Apple M1 performance wise.
