I understand the advantages of higher single-core performance and the difficulties in parallelization. And yes, higher clock speeds mean better performance, all other things being equal. But originally, you said 10 GHz, a record-breaking clock speed, would be advantageous. I replied to say that I doubt that, given the physical limits mentioned in the links I shared above. If what you originally meant was that processors with fewer cores and better raw performance per core is what you need, then I misunderstood. >Have you ever coded a many-core application that runs on thousands of CPUs? Nope. I admit you have more experience in that area than I do, but I don't really see why you brought it up. >Nevertheless, for a specific domain I would need a really high speed single-core CPU. Out of curiosity, which domain do you have in mind?
