The 2x number you're claiming was only for geekbench multithreaded, which was the only multithreaded comparison between those two in the Anandtech article. You're trying to make broad sweeping claims from that one data point. That doesn't work. Take for example the CineBench R23 numbers. The M1 at 7.8k lost to the 15W 4800U in that test (talk about the dangers of a single datapoint!). The 5950X meanwhile puts up numbers in the 25-30k range. That's a hell of a lot more than 2x faster. Similarly in SPECint2017 the M1 @ 8 cores put up a 28.85, whereas the 5950X scores 82.98. Again, a lot more than 2X. This is all ignoring that 2x faster for 4x the performance is also actually a pretty good return anyway. Pay attention to the power curves on a modern CPU or what for example TSMC states about a node improvement. For 7nm to 5nm for example it was either 30% more efficient or 15% faster. Getting the M1 to be >2x faster is going to be a lot harder than cutting the 5950X's power consumption in half (a mild underclock will do that easy - which is how AMD crams 64 of these into 200W for the Epyc CPUs, after all). But nobody cares about a 65w highly multithreaded CPU, either, that's not a market. Whatever Apple comes up with for the Mac Pro would be the relevant comparison for a 5950X.
