Got anything to back that up with?
Its not for nothing AMD makes a big deal out of their 50% performance per watt improvement and that they dont just give their gpu's a 600 watt ceiling allowing them to handily beat big N just at a MUCH higher power consumption.
Do you? To back up yours? Of course you don't. You can quote individuals, or show a couple of YouTube videos about undervolting, but the thing is that both Intel and Nvidia gained market share with power hungry products.
AMD makes a big deal about power consumption the last 7+ years, but it is backfiring in their face the last 2-3 years. People rush to buy power hungry stuff to have the best possible performance, no matter the power consumption. AMD already changed route with Zen 4, letting it turbo as high as possible, while also increasing TDP to 170W, to achieve best possible performance. They will do the same with RDNA 4 or even with RDNA 3, if they come out with a refresh that turbos probably over 3GHz.
AMD is in a desperate position with Nvidia increasing the lead, while Intel is coming from behind to steal OEM sales in the GPU market (from both AMD and Nvidia). At the same time, power hungry Intel CPUs, that are advertised as 16 and 24 core models, while having more E cores than P cores, are taking back market share in the retail market.
AMD is holding up thanks to servers and consoles. If Intel comes out with a good server CPU or even manages in 2-3 years to have something good for consoles to steal that market from AMD, well, many will get what they wised for. Monopolies, stagnation and ridiculous high prices in about everything.
If everyone on the high end didn't care about power consumption, you wouldn't see all these videos demonstrating how to reduce the power consumption of high end Intel and AMD parts. UV is pretty popular nowadays.
People will buy those power hungry models over more efficient models based on a very understandable logic
"I'll get the product that offers the best performance, undervolt it and if I ever need that extra performance, I will run it at defaults or even overclock it".
They will not get the more efficient but slower part, because they wouldn't probably have the option to ... unlock that extra performance when they need to.
People who want every last drop of performance can OC their cards as they wish.
Things changed compared to the past. Companies try to win benchmarks and put price tags on new products based on their optimal performance. If the company A sells the product B with a frequency of 1GHz to keep it efficient, while that product can reach 1.2GHz frequency, it's leaving 20% performance on the table. That means it will be looking 20% slower on benchmark charts and the company will have to price it accordingly, as a 20% slower product. Instead companies try to overclock their new products to their maximum, to achieve maximum performance, to advertise them as fast, to put price tags accordingly.
Let me say it with differently. In the past someone was buying a product that could overclock 30%. That meant "FREE performance". Free is dead today. You buy the product at the highest possible price and then you have the option to LOSE performance, if you wish for efficiency.
