If you have two systems one that draws 250w and take 4 hours, and one that is 350w and takes 25% less time, so 3 hours, then you'll use 300w in total extra.
Even if you only the that 300w per day, then you are talking a huge difference over a 3 year life span. These CPUs are certainly going to be a hard sell to companies trying to hit net zero CO2, which three is pressure on everyone to do.
It's actually pretty embarrassing for Intel really, they provide a massive total percentage of the global market of CPU's and they need to be called out making incredibly inefficient power hungry parts.
People who say it doesn't matter clearly don't give a flying fig about the planet, only themselves.
