You don't need these tricks, you can always increase clocks and speed up memory interfaces. It was a lot harder for Intel to widen the memory interface of the P5 or increase the clocks sufficiently so they made it superscalar. RISC-V gets to take advantage of being produced in 2024 and absorbing all the clock speed and transistor advantages we get for free today because of 6 decades of transistor production.

But how do you explain the 25x performance gap then?

  It costs a lot of money to develop an advanced CPU and deploy on an advanced node. You need a market for the chips to justify that so it's a bit of chicken or egg problem. The gap is slowly closing and I'm looking forward to a RISC-V linux laptop in the next few years.

  RISC-V hasn't maxed out. A new 2.4Ghz clockspeed at 7nm(dev board actually 1.4Ghz) when my old Ryzen 7 5800X at 7nm gets 4.5Ghz. https://www.theregister.com/2024/04/09/sifive_riscv_hifive/ https://www.theregister.com/2024/04/09/sifive_riscv_hifive/

    But increasing the clock speed might give you a 5x speed improvement at most.

      That's not the only thing you can do.
