The latest RISC-V CPU cores from SiFive, the P670 and P470, are targeted at applications where compute density matters.

SiFive is expanding its family of high-end RISC-V CPU cores, aiming to unseat ARMs Cortex-A series in space-constrained, performance-hungry designs such as wearables, robots, and other consumer devices.
The Santa Clara, California-based company said one of the new 64-bit cores, the P670, is its most advanced CPU yet based on the RISC-V architecture. It will compete with ARMs Cortex-A78 processor, which made it into smartphones chips for the first time in 2019. SiFive indicated that the P670 is best suited for a 5-nm process node and packs roughly the same performance as the Cortex-A78 in a 50% smaller space.
To complement it, the company also rolled out the P470 core. It features many of the same building blocks as the P670 in a more compact, less power-hungry package that will compete directly with ARMs Cortex-A55.
