For comparison sake 13900K can do 30500 at 100W PL2.

R24 also is also better for ARM too. It makes use of the cores better than R23 did.
I have seen claims that R24 favours x64 by supporting AVX2/512 but Chips&Cheese review states that it is only using AVX encoding for mostly scalar operations. Only 7% of instructions are using 128b. Therefore most of the register width is unusued [32b arguments, vs 512b register width in extreme case]. According to the review what has changed is that the working set size is too big to fit in LLC so it stresses memory subsystem more compared to R23. In fact it seems that limiting it to mostly scalar operations favour cores that have large number of smaller fp units, as the size of the unit will not make a difference. So whatever gain Zen5 will have over Zen4 will come from improvements to the front-end, load store unit and integer side of the benchmark as the fp side will most likely not see any gains.

Throwing this on the radar. Would be nice if there was a boost clock jump if this HX 375 is for real. Only an NPU jump to 55 TOPs as of now.

Zen 5 mobile seem to have worse performance per clock vs desktop zen 5 in geekbench 6. Hx 370: 2860@5.1ghz

I think that's just a typo. There are a lot of errors in these placeholder websites. ASUS also has weird errors like that on their strix point laptop pages.

Clocks still fluctuate for whatever reason, it's @ 4.8 most of the time. Not sure if it's a reporting issue or the thing can't hit boost clocks consistently.

GNR does not exhibit this kind of behaviour.

No way zen5c is hitting 4.8 GHz so the clock reporting is definitely off...

That’s the key question because a 7945HX does 33400.
A 7945HX is for a different market compared to a Ryzen 370AI. It has (can have) different power envelope, it is a desktop derivative with 16 cores explicitely dedicated to gaming desktop replacement laptops. Its succesor will be the Fire Range lineup.
370AI in an all-purpose mobile APU aimed at the same market of the 8945H/HS .
