This may actually beat the Z1 Extreme as it only has 4P+4E cores without HT (so it's more similar to the Steam Deck's Aerith/Sephiroth APU) with 8 Xe (Arc) cores, which already does beat 780M at the same TDP.

Hopefully MSI got the cooling down right for their 2nd generation handhelds, but it should be easy since its only 4+4 cores.
The only issue I can see is if MSI screwed up the cooling for these 2nd gen. Claws, but it shouldn't be hard as its just 4P+4E without HT. Take note, in the video he power-limited the 258V to the TDPs that should be attainable in handhelds, especially since the ROG Ally X also goes up to max 30W TDP stock.
Also that Zenbook S14 only has one fan with two heatpipes, so should be more or less like the cooling systems of the handhelds. I had to double check this, but it actually has two fans on two heatpipes:

Doesn't change anything since both ROG Allys and the 1st gen MSI Claws have dual fans as well.
EDIT: For what it's worth, I gave the Claw A1M series a bad score (I even returned my Claw, LOL) as it needed 35W to 45W TDP to even beat the Z1 Extreme handhelds and the minimum stock TDP was 20W
, but that just shows the inefficiency of Meteor Lake CPUs and early Arc graphics.
