RISC-V chip manufacturer SiFive announced the launch of two new products, SiFive Performance P870 CPU and SiFive Intelligence X390, mainly for high-performance computing and AI/ML applications.
SiFive Performance P870 and SiFive Intelligence X390 offer low power consumption, compute density and vector computing capabilities designed to deliver significant performance improvements for data-intensive computing applications in consumer electronics, automotive technology and infrastructure.
SiFive executives emphasized the company's commitment to driving high-performance RISC-V innovation and closing the gap with other instruction set architectures. He also stated that the growing demand for semiconductors in fields such as consumer electronics and infrastructure has promoted the rapid expansion of the RISC-V ecosystem.
SiFive Performance P870
The P870 is designed for high-performance consumer applications and can also be used with vector processors in data centers. Setting new standards for RISC-V performance in instruction set architecture availability, throughput, parallelism, and memory bandwidth .
The P870 has a 6-issue out-of-order execution core and a shared cluster cache. Compared with the previous generation SiFive performance processor, the P870 peak single-thread performance has increased by 50% (specINT2k6), and can support up to 32- core clusters .
In addition, the P870 is fully compatible with Google's platform requirements for Android on RISC-V and offers other proven SiFive features: 128b VLEN-length RISC-V Vector (RVV), vector encryption and hypervisor extensions, IOMMU and Advanced Interrupt Architecture (AIA) ), non-inclusive L3 cache, and proven RISC-V WorldGuard security design.
SiFive Intelligence X390
SiFive Intelligence X390 builds on its predecessor, SiFive Intelligence X280, with a single-core configuration, double vector lengths, and dual vector ALUs, delivering a 4x increase in vector computing performance and a 4x increase in sustained data bandwidth.
With the SiFive Vector Coprocessor Interface Extensions (VCIX), companies can easily add their own vector instructions and/or acceleration hardware, allowing users to dramatically increase performance through custom instructions.
Features include: 1024-bit VLEN, 512-bit DLEN, single/dual vector ALU, VCIX (2048-bit output, 1024-bit input).
“ Combining the P870 high-performance general-purpose computing SoC with a high-performance NPU cluster consisting of X390 and customer AI hardware engines provides product designers with a highly flexible, low-power and programmable solution for complex workloads. Excellent compute density. ”
SiFive highlighted strong customer interest in these combined solutions and said some of these customers have experienced success in chip development and commercialization using high-performance SiFive products.
