Speed of memory has been the bottleneck all along. More transistors are only useful if they are L1 cache, but to take advantage of larger caches we need to change the OS/languages we use. I would say 1 Gflops/Watt is peak 32-bit CPU, I think most people should try and work from that number and keep energy usage as low as possible. Raspberry 4 for desktop! 28nm is enough, going smaller creates more problems than it solves.
