If you consider the mainstream products of Intel and Nvidia, they have way more moderate power consumption. These products with massive power draw are ultra enthusiast products. They are an outlier. You could build a great PC now with a RTX 3060 and a mainstream CPU that would be fine with a 500~ watt PSU.

As technologists, we should support manufacturers pushing the limit in power and performance. It helps drive overall efficiency and move technology forward.

Power consumption doubled at least even on mainstream and keep increasing gen over gen.

1070 vs 3070 is +52٪ average (145 vs 220w) and +66% (154 vs 250w) sustained.

2070 vs 3070 is +10% (195) or +24% (203) sustained.

Even the 3060 you defend draws power as older flagships and 500w arent enough even for mainstream gaming.

And it keeps getting worse both on gpu and cpu size.

We aren't technologists but consumers, and reality is that x86 and gpus are in near duopolys so the 3 companies involved have little reasons to do a better job and it's clear Apple socs or more and more cloud moving into arm have not been enough of wake up calls.

And yet energy efficiency continues to improve: https://tpucdn.com/review/nvidia-geforce-rtx-3080-ti-founder...

In fact, the 3070 is significantly more power efficient than the 1070 is. Because while yes power is up 50%, performance is up 100%. So performance per watt has continued to improve even as power consumption has also increased.

The reality of power consumption is that it's the main lever to pull right now to deliver generational gains. It's the same lever Apple pulled for the M2 even.

You mean the ARM enterprise SoCs that use just as much power as x86 does to deliver on average worse performance?

Yep, I’m using a 500w psu to power my gaming pc with a rtx 3060 ti and a 12700k cpu
where is the amd/nvidia/intel product that offers comparable performance at a power draw that is anywhere near m1?
I believe AMD Ryzen 6000 mobile cpus can hold their own against the apple m1. They have comparable performance and can be set by the manufacturer at a TDP comparable to the m1(and still perform well). Except for mainly m1 optimized apps, GPU performance should be pretty comparable too. Ryzen integrated graphics perform better in gaming.
