       | Unless you're comparing price/performance, since nowadays there's

         | That is _because_ all cutting-edge chips use TSMC.

         | No competition means price per transistor can stay consistent
         | or even rise, which is one part of why most modern CPUs and
         | GPUs have price/performance ratios that are the same or worse
         | than their previous-generation counterparts.

         | Of course not, but that isn't going to stop people from doing
         | it, nor is it going to stop people from going "x86 is dead"
         | when comparing last-gen-node AMD processors to CPUs only Apple
         | can use (conveniently forgetting that Qualcomm's products
         | underperform at the same process node).
