The Vivobook 16 uses soldered DDR5-5600 (worst of both world, slow and non upgradeable) not LPDDR5x-8000 that should explain the difference. Power limit wise the chassis is actually quite generous. 
			
			
			
				the vivobook 16 gpu performance is limited due to running single channel ram...what a worst article like userbenchmark...
			
			
			
				And maybe even drivers not being optimized yet.
Seems like an article that prefers to have a flashy title than to actually investigate the issue itself.

Not seeing any literature supporting this single-channel claim, but that would explain the poor performance.
