Alibaba Crafts A 16-Core RISC-V Chip @ 2.5GHz
Alibaba this week announced a RISC-V 64-bit processor comprised of 16 cores at 2.5GHz. The Chinese RISC-V CPU is fabbed at 12nm and this RISC-V processor supports out of order execution. This Alibaba design achieves a 7.1 Coremark/MHz rating, a great deal faster than any other publicly announced RISC-V processor. It's still not as fast as say the newest AMD Ryzen 9 or Intel Core i7/i9 parts, but it's certainly much better than all of the other RISC-V processors/SoCs we've seen announced to date. Unfortunately additional details on this Alibaba design are light.

...kind of depends on how you write the compiler. The more registers with the same functionality there are, the more types of operations and operands can be register-resident without having to resort to stack-flippery.
