By Rich Pell

The new range-topping member of the company’s SiFive Performance family, the SiFive Performance P650 processor will bring RISC-V into new markets and applications, says the company. The SiFive Performance P650 will enable RISC-V designs for performance-demanding application processor markets from data center to edge, automotive, compute, mobile and more.

“SiFive’s mission is to answer the semiconductor industry’s call for more processor IP choices,” says Dr. Yunsup Lee, co-founder and CTO, SiFive. “SiFive is singularly focused on bringing innovative processor technology based on the RISC-V architecture to market. This announcement is the next step towards our long-term vision of bringing RISC-V processors to all performance-hungry applications.”

The SiFive Performance P650 processor builds upon the SiFive Performance P550 processor, maintaining an efficient core pipeline while expanding the processor instruction-issue width to deliver a 40% performance increase per clock cycle. Additional architecture enhancements improve maximum clock frequency, achieving an overall 50% performance gain compared to the company’s previous fastest processor.

With a projected score of 11+ SPECInt2006/GHz, the SiFive Performance P650 brings RISC-V into a new category of high-end computing applications, says the company. The SiFive Performance P650 is scalable to sixteen cores using a coherent multicore complex, complete with essential system components such as platform-level memory management and interrupt control units, and supports the new RISC-V hypervisor extension for virtualization. SiFive will offer an “Architecture Preview” to select lead customers, for evaluation of the SiFive Performance P650 ahead of general availability.

The SiFive Performance P650 Architecture Preview will be offered to lead customers in Q1 of 2022 with general availability coming mid-year.
