In the end that sum it takes energy during gaming is meaningless. I spend more on coffee while playing than to electricity.
Note: this isn't about debating which platform is best, rather understanding power consumption impact and the cost to your budget.
Are these costs major? Life changing? Absolutely not. But you should care about them and make decisions incorporating them, not ignoring it as if power consumption is irrelevant even if doubled!
Can additional performance allow me to do more while e.g gaming?
Like doing some stuff in the background, having VMs, IDEs, Dockers running?
See the insanity of optimizing couple of watts from PC? I don't play 12 hours a day, I play after work in the evenings - at best few hours a day, but not every day.
My workstation's power usage does not have any impact on my life. Even if doubled, tripled, quadruppled, it would be lost in margins of everything else where I use electricity.
PS5 eats about the same amount of power to be fair (or my XSX) so there's not much to save here. Also, they're a bit slower than my desktop and do not provide the flexibility.
Proper gaming performance requires power as no one has invented any golden goose to reduce it (not AMD, not NVIDIA, not Apple) at the same performance. I'd even wonder if Apple's usage of GPU in M2 Ultra is that power efficient when looking at the real world games as the fps counters are so low.
Theoretical performance is pointless in the end if it doesn't actually crunch anything that fast in reality. Maybe the glue architecture is only nice on paper and that's why Apple after years of ignoring specs is now only advertising specs on their GPU parts, not what it could do.
