For a moment ASUS Zenbook 14 OLED UX3402ZA 16GB / i5-1240P was available on for £749, which I think was a good price.

There is no evidence that 1240p has more Power Efficiency than 1135g7 please be more truthful.

There are tones of evidence. Please tell me, why in the world would literally *all* mobile chips use efficiency/performance cores? Maybe because that's cheaper? Or maybe because it's both cheaper and better for energy consumption? Comments like "Oh but that's not true" which make claims without so-called "evidence" should be treated like barking.
