The speed and the efficiency of these chips are just insane:

"As just one example, a recent microprocessor design using RISC-V has a clock speed of 5 gigahertz, well above a recent, top-of-the-line Intel Xeon server chip, E7, running at 3.2 gigahertz. Yet the novel RISC-V chip burns just 1 watt of power at 1.1 volts, less than one percent of the power burned by the Intel Xeon." (Source)

Perhaps reading from the source is better? 🙂 https://riscv.org/

Sorry if I'm preaching to the choir, given the type of Lemmy users, in terms of already knowing about RISC-V and in terms of assuming y'all know about the M1. Still, I just learned about RISC-V today, and I'm awed!
