Hmmmmmm shares a report from Ars Technica: Micro Magic Inc. — a small electronic design firm in Sunnyvale, California — has produced a prototype CPU that is several times more efficient than world-leading competitors, while retaining reasonable raw performance. EE Times reported on the company’s new prototype CPU, which appears to be the fastest RISC-V CPU in the world. Micro Magic adviser Andy Huang claimed the CPU could produce 13,000 CoreMarks (more on that later) at 5GHz and 1.1V while also putting out 11,000 CoreMarks at 4.25GHz — the latter all while consuming only 200mW. Huang demonstrated the CPU — running on an Odroid board — to EE Times at 4.327GHz/0.8V and 5.19GHz/1.1V. Later the same week, Micro Magic announced the same CPU could produce over 8,000 CoreMarks at 3GHz while consuming only 69mW of power.
Part of the difficulty in evaluating Micro Magic’s claim for its new CPU lies in figuring out just what a CoreMark is and how many of them are needed to make a fast CPU. It’s a deliberately simplified CPU benchmarking tool released by the Embedded Microprocessor Benchmark Consortium, intended to be as platform-neutral and simple to build and use as possible. CoreMark focuses solely on the core pipeline functions of a CPU, including basic read/write, integer, and control operations. This specifically avoids most effects of system differences in memory, I/O, and so forth. […] With that said, it’s worth pointing out that — if we take Micro Magic’s numbers for granted — they’re already beating the performance of some solid mobile phone CPUs. Even at its efficiency-first 3GHz clockrate, the Micro Magic CPU outperformed a Qualcomm Snapdragon 820. The Snapdragon 820 isn’t world-class anymore, but it’s no slouch, either — it was the processor in the U.S. version of Samsung’s Galaxy S7.
