At Hot Chips 2023, SiFive introduced the new high-performance P870 RISC-V core and its automotive equivalent, the P870-A core, discussing the overall state of RISC-V, its previous generation cores, and future development directions.
The P870 and P870-A RISC-V cores are new additions to SiFive’s Performance series, compatible with the RISC-V RVA23 profile, and are successors to the SiFive P670 core. The SpecINT2k6 benchmark report shows that the P870 scores 17 points per GHz, while the P670 scores 13.2 points per GHz (comparable to the Arm Cortex-A78), indicating a performance improvement of about 29% at the same frequency.
