Re: "as fast as the fastest PCs."
@Dave 126 Desktop CPUs haven’t been getting much faster at single threaded tasks in recent years because Intel et al have run out of things they can do to make them faster. Clock speeds have hit limits imposed by the switching speed of silicon vs power consumption. All the optimisations they can think of are implemented (a modern CPU uses a huge number of transistors). Fabrication process improvements have slowed to a crawl. They’re left with stuffing more cores onto a chip and adding custom hardware for specific tasks like video encoding/decoding
