Micro Magic Inc.—a small digital design agency in Sunnyvale, California—has produced a prototype CPU that’s a number of instances extra environment friendly than world-leading opponents, whereas retaining affordable uncooked efficiency.

We first observed Micro Magic’s claims earlier this week, when EE Occasions reported on the corporate’s new prototype CPU, which seems to be the quickest RISC-V CPU on the earth. Micro Magic advisor Andy Huang claimed the CPU may produce 13,000 CoreMarks (extra on that later) at 5GHz and 1.1V whereas additionally placing out 11,000 CoreMarks at 4.25GHz—the latter, all whereas consuming solely 200mW. Huang demonstrated the CPU—operating on an Odroid board—to EE Occasions at 4.327GHz/0.8V, and 5.19GHz/1.1V.

Later the identical week, Micro Magic introduced the identical CPU may produce over 8,000 CoreMarks at 3GHz whereas consuming solely 69mW of energy.
