I'd be interested in an x86-64 processor that took the 1+3+4 approach of the Snapdragon 875. One big core with a super high clock rate and massive IPC, three smaller ones, and four that are smaller still. A desktop CPU with a single-core performance equal to half a normal 8-core chip would be an absolutely incredible tool for IPC-constrained applications like game console emulation.

- MBCook 6y agoThe bigger problem is you need operating system support. Linux/android has it. iOS has it. If iOS has it there’s a very good chance that macOS has it (we’ll probably find out on Tuesday). What does Windows support heterogeneous cores at all? I don’t think it does. And until that happens, would you be able to sell a chip to the public?
- wmf 6y agoSurface ARM laptops have big.little so there must be some kind of support but I don't have any confidence that it's good. It will take MS a while to get it refined. People are probably better off disabling the little cores so threads don't slow down by getting accidentally scheduled on them.
- kasabali 6y agoWell said. A lot of people I see on hardware forums seem to have the deception that we'd suddenly have 10 GHz cores had big.LITTLE x86 processors appear. Reality is we'd have few of exact same cores we have today and a dozen more atom level cores put there solely for the purpose of marketing spec race.
- rasz 6y agoGreat idea, now sell me one with 8 of those big cores and none of the rubbish ones.
