Sorry that I'm replying to such old posts. I have recently spent a lot of time researching this topic, including reading all the posts on this topic.
While reading various websites and forums, I came across at least several configurations where the power consumption was relatively low, despite the use of a 12th generation processor. I'm curious, do you still think that newer generations of Intel processors cannot be energy efficient compared to older generations? Could your assessment be due to observations of C0 stepping instead of H0? I am referring to this issue. Apparently the differences between one stepping and another are large.
Finally, the most important questions.
I know it's difficult to estimate because the processor is only one of the components that influence power consumption, but is it possible to estimate the differences in power consumption between the 10th and 12th generations?
Is it worth looking at older generations of processors in 2024, such as the 10th generation?
