SiFive Announces New Datacenter Processor
SiFive, Inc., a leader in RISC-V computing, has unveiled its latest product, the SiFive Performance P870-D datacenter processor. This new processor is designed to meet the needs of customers requiring highly parallelizable infrastructure workloads such as video streaming, storage, and web appliances. When paired with products from the SiFive Intelligence family, datacenter architects can create a high-performance and energy-efficient compute subsystem for AI applications.
Building on the success of the P870, the P870-D supports the open AMBA CHI protocol, giving customers the flexibility to scale the number of clusters. This scalability allows for increased performance while minimizing power consumption. By utilizing a standard CHI bus, the P870-D enables customers to scale up to 256 cores and utilize industry-standard protocols like Compute Express Link (CXL) and CHI chip to chip (C2C) for coherent high core count heterogeneous SoCs and chiplet configurations.
The P870-D processor enables the creation of infrastructure SoCs with higher compute density compared to competitors, offering improved performance per watt metrics for parallel compute tasks. This results in advantages in total cost of ownership, which is crucial as the industry seeks ways to reduce the cost of training AI models. Additionally, the power-efficiency of the P870-D aligns with the industry's focus on sustainability.
SiFive is collaborating with ecosystem partners to streamline system development. For example, Arteris has worked with SiFive to deliver an emulation-ready reference design with the X280 and P870-D processors. By integrating SiFive's RISC-V processors with Arteris' Network-on-Chip (NoC) IP, customers can accelerate development and bring products to market faster.
Key Features:
- Scalable to 256 cores
- Compatible with RVA23 profile
- Supports RISC-V Sv57 extension
- Integrates Advanced Interrupt Architecture (AIA)
The P870-D processor is sampling to lead customers now, with a final production release expected by the end of 2024.
