Expected this MCM means basically stacked gpu dies, so 2, 3, 4 card gpu sli/crossfire of past is now on single gpu. However power requirements don't go away, you save on additional components like additional VRAM but each additional gpu die still consumes power, stacking more means higher power usage as scales linear.
Well im done with high end cards then, iv always bought the x80 cards since the overheating gtx480, guess il knock it down to x70 or even less if the x60 or x60ti cards are good enough in future, good thing i skipped the 3080 and will wait and see what the 4070 does
And the energy to power them comes 100% from wind and solar? No mate, it doesn't.
With cars we are just brushing the problem under the carpet, maybe creating a bigger one because of the batteries.
It's absurd that I undervolted my RX580 by 150mV and it consumes allot less power for virtually the same performance. We are burning the planet for capitalism because 5% difference in performance will sell.

I undervolt my 3700x to 1.2v and perf is no different in games as im GPU limited at 4k, i do it for temps, nothing to do with the planet, the planet will do just fine, it was here before life and will be here long after, the planet will win the long game.
Next time HH will hold a contest for a graphic card will give away also a new power supply as a bonus 😀 ......
.... for the sake of it ... SUNFlower 😀 🙂)))) that will be hillarious
GTFO both Nvidia and AMD if they go that route,I have problem with my 1070 being more like 170watt and around 200+ under full load, where are the 150watt cards those cards i always bought there non extant now
I just hope that Nvidia includes a longer adapter cable this time around as the one for the previous founders cards would ruin any aesthetic oriented builds and for just for cable management in general.
"850w psu was enough" no it never was the optimal load both for efficiency and durability of your psu is near 50% load so with a 5950x and a 3090 we're supposed to run 1600w psu
I need to repeat this every time but if you are a car owner and you don't know you shouldn't drive it at the redline nonstop because either the engine will blow up or you will melt everything in the engine compartment then sure buy a psu that is "just enough" risking your gpu motherboard and cpu to spare 100$ not smart
if you overload your psu it will blow up and destroy your gpu/motherboard guess how I know, it's not a mistake you make twice but more importantly it's a mistake I made when gpus where 450$ not 3000$ so maybe don't cheap out on the psu in 2021 bad timing

Agree with everything you said but there is no need to buy PSU that double the total system power consumption. 1600W Platinum PSU is like triple the price of a good 1000W Gold PSU or double the price of 1200W platinum PSU.
All modern PSU maintain almost flat efficiency rating across all load, at 90% load it would only lose like 3% efficiency compare to a 50% load.
Furthermore the rated PSU wattage rating is for Output, meanwhile the wall measurement is Input. If someone is measuring 800W at the wall, that means his total system power consumption is only 800 x 90%efficiency = 720W

There is no shame in being energy consumption aware.
Yes there will be life, just maybe a little less variegated and nice, or maybe things will collapse all of a sudden. But in general energy consumption does matter, and we can't negate that.

Not necessarily. When you're stacking chips, you need to lower the voltage and clock speeds or else the chips farthest from the heatsink are going to overheat. Even Intel lapping a few micrometers off their dies made all the difference in cooling. When it comes to adjusting voltage and clock speeds, the difference in power usage does not scale linearly. When it comes to GPUs, clock speed isn't all that important until all of your cores are maxed out. But if we can take modern GPU designs and double or even triple the amount of transistors, they don't have to be clocked as high as they are now. So, a MCM GPU will proportionately consume a lot less power, relative to the transistor count.
k3vst3r:
Nothing stop people limiting these new cards to whatever wattage they feel comfortable with?
It doesn't make sense to pay extra only to deliberately cripple performance. For argument's sake, let's say you try to maintain the performance but just undervolt, where you get a healthy 25% wattage reduction. A 25% reduction of a 600W GPU is still a whopping 450W. A 25% reduction of 450W is 338W, which is still high enough to need more than 2x 8-pin PCIe connectors.
Kaleid:
Umh nope. Not buying anything over 250w
300W is my limit, though I'd much rather go down to 250W where possible.
