hmmm
So, on Windows, same benchmarks, Bay Trail vs Snapdragon 800 - Snapdragon uses 30% less power but Mr Watt then admits that Bay Trail is faster without going into specifics?
But that's the crucial thing, the crux of the argument! If Snapdragon also does 30% less work, then they are essentially equal - the argument moves to idle power draw and OS power management.
I suspect that actually Snapdragon does below 70% of the work of Bay Trail, making it actually less performance/watt efficient - and it's not just a wild guess, there's some old data to base it on:

SunSpider: Snapdragon 800 has 8% less performance
Kraken: Snapdragon 800 has 46% less performance
Octane: Snapdragon 800 has 52% less performance
These are Anandtech numbers from September 2013 - it'd be good if someone found some newer ones.
