Interesting part is they have actually been open for a week now. They did a quiet opening on the 25th and it was still busy that day

I see what's going on, they have two HX370 laptops:
Laptop MC score Avg Power
P16 1213 113 W
S16 921 29 W
M3 Pro 1059 (30 W?)
Any more power, and the CPU is much less power efficient, 300% increase in power for 30% increase in performance.

I think the OC might have mis-read the power numbers, 110 W is well into desktop CPU power range. Here is a excerpt from Anand Tech:
> In our peak power test, the Ryzen AI 9 HX 370 ramped up and peaked at 33 W.

119W for hx370 looks extremely sus, seems to me more like the system level power consumption and not CPU-only.
According to phoronix [1,2], in their blender CPU test, they measured a peak of 33W.
Here max power numbers from some other tests that I know are multi-threaded:
--
Linux 6.8 Compilation: 33.13 W
LLVM Compilation: 33.25 W
--
If I plug in 33W into your equation, that would give us score of HX 370: 104 PPA
This supports the HX 370 being pretty power efficient, although still not as power efficient as M3.

That is fair, I was taught that decoders for x86 are less efficient and more power hungry than RISC ISAs because of their variable length instructions.
I remember being told (and it might be wrong) that ARM can decode multiple instructions in parallel because the CPU knows where the next instruction starts, but for x86, you'd have to decode the instructions in order.

I have heard that part of the reason for little coverage of ryzen mobile CPUs is their limited availability as AMD was focussing on using the fab capacity for server chips.

IMO, the most interesting thing about this line is the battery life---within an hour of MBP3 and within 2 hours of Asus's Qualcomm. Making it comparable to ARM architectures.
Which is a little surprising because ARM is commonly believed to be much more power efficient than x86.

These are interesting results and make a strong case for AMD over Qualcomm, especially in battery life:
ASUS S16 (Qualcomm): 13h 39m
Apple MacBook Pro (M3): 12h 35m
ASUS S16 (AMD): 11h 10m
ASUS S15 (Intel): 9h 15m
ASUS S16 (Qualcomm): 1,138
ASUS S16 (AMD): 997
Apple MacBook Pro (M3): 716
Apple MacBook Pro (M3): 141
ASUS S16 (AMD): 113
ASUS S16 (Qualcomm): 108
