I've got a similar spec laptop with 24 core (8P + 16E) i9-13900HX that is probably quite comparable or maybe a bit better especially on burst workloads e.g. building software as the max turbo is 500 MHz higher and both similar all-cores boost (3.8-3.9 or so) but I have more cores. It's going to be a long time before we see RISC-V at this level, at least on a per-core basis. I think we'll see around 2020 x86/Apple M1 performance in 2026/27. Late this year we'll see a 16 core RISC-V with around Nehalem or Sandy Bridge performance. But 16 core, so something like a Xeon of that generation -- I had one in a Mac Pro back in 2009. That's a pretty respectable computer. Milk-V says they'll have a board with one for $120 -- I suspect that's with zero or very low RAM, no storage. SiPeed says $300 and that's probably with a good chunk of RAM and eMMC. That will be RISC-V's RK3588 (Rock 5, Orange Pi 5) or Raspberry Pi 5 moment, though it actually leapfrogs those by quite a bit, in both per core speed and number of cores.

Thanks, I think your timeline makes a lot of sense. Considering that, my gut tells me it may be 15 to 20 years before RISC-V catches up (since Intel and AMD and ARM won't be laying down). What do you think the timeline looks like? Do you think RISC-V will catch up anytime within the next 15 to 20 years? Is it more optimistic than that? If a company like AMD spun up a RISC-V division (oh god that would be so amazing), that would obviously greatly accelerate the timetable. I lack a whole lot of strategic info for decision making, but my instinct is to think that could be very good for AMD. There would be some cannabilization, but I don't think nearly as much as you would think, but the big payoff is that if RISC-V is going to be big (which I think it is), they become the de-facto leaders and can own it, much the way Nvidia did with GPUs.
