SiFive

Performance

The SiFive Performance™ family of RISC-V processors is designed for maximum throughput and performance efficiency for datacenter workloads, ranging from Web servers and multimedia processing to Networking and Storage. The Performance family provides 64-bit, Out of Order (OoO) Cores for a range of design points based on workload requirements. These range from 3 wide to 6 wide OoO cores with 2 dedicated vector engines for AI workloads. For customers, this provides a balanced best-in-class energy and area-efficient portfolio of Cores. The SiFive Performance Family represents the future of Compute.

RISC-V Processors

Balanced Performance

With the ever-expanding SiFive portfolio, RISC-V has rapidly evolved from its early market traction within the embedded processor market to take on the high-performance application space. SiFive is leading the way with our Performance family, a broad range of feature-rich-OS application processors, from the entry-level, dual-issue multistage pipeline P270 all the way up to the latest out-of-order processors.

Where power, footprint, and cost constraints generally override the need for high performance. Add to these constraints the complexity of delivering new RISC-V technology that stands shoulder to shoulder with advanced proprietary architectures, and it is clear that a large category of processor consumers has, before now, gone underserved without a variety of high-performance choices from the market.
