SiFive has announced two RISC-V “Performance” cores with Performance P550 that should be the fastest 64-bit RISC-V processor so far with a SPECInt 2006 score of 8.65/GHz, as well as a Performance P270 Linux capable processor with full support for the RISC-V vector extension v1.0 rc. SiFive Performance P550 P550 highlights: RISC-V RV64GBC ISA 13 stage, 3-issue high-performance out-of-order pipeline Supports multicore coherence with up to 4 cores in a core complex Private 32KB+32KB L1 cache and a private 256KB L2 cache per core Up to 4MB L3 cache in a four-core cluster SPECint 2006 – 8.65/GHz 2.4 GHz in 7nm with a footprint of less than 0.25 mm SiFive compares the Performance P550 core to Arm’s Cortex-A75 with higher performance in SPECint2006 and SPECfp2006 integer/floating-point benchmark, all a much smaller area which would enable a quad-core P550 cluster on about the same footprint as a single Cortex-A75 core.
