Highest performance four-issue, out-of-order RISC-V vector application processors

Overview

The latest generation SiFive Performance™ P600-Series processors are the highest performance commercially licensable RISC-V processors.

The P670 vector application processor features a thirteen-stage, four-issue, out-of-order pipeline and offers best-in-class performance, with >50% uplift over the SiFive Performance P550, while maintaining a significant performance-per-area advantage compared to the Arm® Cortex®-A78.

For applications that don't require vector compute, or for more area-constrained markets, the P650 offers similar performance levels in a smaller area footprint.
