SiFive Performance
P870/P870-A

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.

For Automotive applications the P870-A is designed to meet the specific needs of manufacturers. Contact sales for more information on this product.
