I am somewhat skeptical about total performance claims as many notebook manufacturers have been moving to ARM for efficiency and not total performance.

Current top of the line for notebooks would be the Qualcomm 8cx (ARM, 7? Watts) and AMD 4800U (x86-64, 15 Watts TDP) from quick search around. Would be interesting to see independent reviewers benchmarking those 2 in comparison to Apple's first in-house processor.

Here are some spec comparisons for the time being:
