I was referring to Package power because package includes powering on things like L3 cache which is used by the CPU core.Mobile Zen never consumes >20W for pure ST loads. Desktop does, mobile is usually around 15W. It also comes with lower peak performance though, so that's to be expected.
For iso-performance Zen 4 will likely be significantly more competitive with Apple's current end cores in performance/W. A lot of power is used for that last roughly 15% performance. To put things into perspective, Zen 4 uses similar levels of power for 4.5GHz as Zen 3 uses for 3.5GHz. That being said, AMD still have a significant disadvantage on power coming from their uncore by comparison however - what I said only applies to looking at the core power only.
For 1T, it seems like the package power is 24w. Core itself is 12.3w.
Here's my M1 Pro CPU wattage data during ST portion of Geekbench5.
Wattage info is shown every 1 second.
We can see that the M1 Pro stays below 2w for most the ST test. It peaked at 5w for 1 second.
I'm not an expert in CPU testing nor do I have a Zen3 or M2 laptop. But at the very least, it seems like M1 is roughly 3-6x more efficient than Zen3 in ST.
