SiFive, a leading RISC-V processor design firm, recently introduced two innovative chip designs aimed at revolutionizing high-performance computing across various industries. The SiFive Performance P870 and SiFive Intelligence X390 chips were officially announced at a press and analyst event held in Santa Clara, California. These designs, based on the open RISC-V architecture, offer exceptional performance, low power consumption, and vector compute capability. With these processors, SiFive aims to provide a significant boost to data-intensive computing applications in domains such as consumer electronics, automotive technology, and infrastructure.
SiFive executives emphasized the company’s commitment to driving high-performance RISC-V innovation and bridging the gap with other instruction set architectures in the market. The RISC-V ecosystem has been rapidly expanding, fueled by the growing demand for semiconductors in sectors like consumer electronics and infrastructure. SiFive CEO Patrick Little highlighted the flexibility of SiFive’s RISC-V solutions, allowing companies to address the unique computing requirements of these segments and capitalize on the momentum around generative AI and other cutting-edge applications.
The SiFive Performance P870 is designed specifically for high-performance consumer applications and can also be utilized alongside a vector processor in data centers. This chip sets a new standard for RISC-V performance, offering availability in terms of instruction set architecture, high throughput, parallelism, and exceptional memory bandwidth. With a 50% peak single-thread performance upgrade compared to previous SiFive Performance processors, the P870 features a six-wide out-of-order core and a shared cluster cache that supports up to a 32-core cluster.
Building upon the success of its predecessor, the SiFive Intelligence X280, the SiFive Intelligence X390 chip is designed to combine AI and ML applications with hardware accelerators for mobile, infrastructure, and automotive applications. With its single-core configuration, the X390 offers a four-fold improvement in vector computation, thanks to its doubled vector length and dual vector ALUs. This leads to quadruple the amount of sustained data bandwidth. The SiFive Vector Coprocessor Interface eXtension (VCIX) provides companies with the flexibility to add their own vector instructions and/or acceleration hardware, enabling unprecedented performance enhancement.
By combining the SiFive Performance P870 and SiFive Intelligence X390 with a high-performance NPU cluster, SiFive offers product designers an agile and programmable solution for generative AI applications. This combined solution provides superior compute density, low power consumption, and exceptional flexibility for handling complex workloads. SiFive emphasized the strong interest from customers in these combined solutions, with several already achieving success in silicon development and commercialization using high-performance SiFive products.
As one of the pioneers in RISC-V, SiFive is committed to transforming the future of computing by harnessing the limitless potential of this architecture for high-performance and data-intensive applications. The company has raised significant funds, employed over 500 professionals across multiple locations, and recorded 350 design wins. Its customer base includes renowned names such as Intel, Amazon, Qualcomm, Samsung, Google, and NASA. SiFive’s continuous collaboration with partners across the ecosystem ensures that the software, security, and flexibility benefits of the open standard RISC-V platform are readily available for SiFive processors, enabling companies to commercialize their SiFive-powered products.
SiFive acknowledges its rivals in the processor market, particularly Arm. SiFive CEO Patrick Little mentioned that SiFive’s top customers include all of Arm’s top customers, particularly in the mobile domain. While Arm has been a dominant player in the industry for decades, SiFive aims to challenge the status quo by offering 30% to 40% better power efficiency and compute density compared to Arm’s solutions. Although it may take some time for SiFive’s advancements to reach their full potential, the company is confident that RISC-V is the fastest-growing software ecosystem, and their complete solutions make them an attractive choice for companies in need of agile hardware.
Little also highlighted SiFive’s progress in penetrating various U.S. government procurements. SiFive’s success in markets such as China, automotive, and more has been further amplified by the recent Arm IPO, which brought attention to the potential of alternative architectures. Despite export controls imposed on certain advanced chips, SiFive’s products are not yet restricted from being used by Chinese customers. This gives SiFive a significant advantage in the Chinese market, which is regarded as a hotspot for sales.
SiFive’s introduction of the SiFive Performance P870 and SiFive Intelligence X390 chips reflects the company’s commitment to revolutionizing high-performance computing through innovative RISC-V designs. SiFive’s ability to provide complete solutions, its growing customer base, and its continuous collaborations position the company as a major player in the processor market. As RISC-V gains traction across various industries, SiFive aims to lead the charge with its high-performance, low power consumption, and flexible solutions that meet the evolving demands of data-intensive computing applications. With its robust ecosystem and commitment to innovation, SiFive is well-positioned to drive the future of computing.
