If you benchmark the AMD 7xxx series aganst the Apple chips while considering their power budget, AMD is on par or on top.
Battery life is strongly tied to software though, and here Apple has the upper hand. However, if you use Chrome vs Safari, you will notice degraded battery life on Mac OS too.

Still way better than non-M chips.
I've done the runaround and used Safari, Orion, Chrome, Arc, and back to Firefox on my M1 MBP. Some are better than others, but the machine overall is still superior.
