SiFive Performance
P870/P870A

The highest performance RISC-V core is ideal for consumer applications or used in conjunction with a vector processor in the datacenter. The P870 sets an impressive, new RISC-V performance bar across instruction availability, throughput, parallelism and memory bandwidth. 

Bringing a 50% peak single thread performance upgrade (specINT2k6) over the previous generation Performance processors, the P870 is a six-wide, out-of-order core, meeting RVA 23, with a shared cluster cache enabling up to a 32-core cluster. High execution throughput comes with more instruction sets per cycle, more ALU and more branch units.

The P870A is designed for Automotive applications. For more information contact your sales representative.
