Open-source high-performance RISC-V processor

5-6 GHz is a party trick of low core count CPUs (e.g. 4 or 8 cores) that use 250+ W of power to get less than twice the performance they can get at 25 W.

There is a sixty four core OoO RISC-V chip (SG2042) being demoed on a dev board in the last weeks. It runs at 2.0 GHz and has quite a bit of aggregate performance, at lower energy usage than an 8 core i9 running at 6 GHz.

AAA games want raw thread performance more than a huge core count.

I am afraid, but the GHz of RISC-V core for high performance desktop will have to go significantly higher.

That said, for self-hosted servers, and even some servers, RISC-V may already be ready for prime time.

There's nothing (other than loss of efficiency, which matters in these server-focused chips) in the way of higher clocks.

oh, and when I said compilers, that's for legacy code, since with a standard world-wide ISA, it is the start of the assembly era.
