I'm glad someone finally started comparing state of the art vs state of art.
Most comparisons have been M1 vs the frankly dated Intel offerings with the previous Mac product line.
So things to remember would be that power/performance is not linear and so 5800 like CPU could be scaled back in power consumption without sacrificing the same proportion of it's performance. Also, 5800X is on TSMC 7nm process where as M1 is on the 5nm; this difference will have a measurable impact on performance and power consumption.
