Benchmarking Arm Neoverse N2, SiFive launches data center-level RISC-V core design P870-D

According to news from this website on August 15, RISC-V IP company SiFive announced yesterday (local time) the launch of the P870-D CPU design for data center applications.

P870-D is built on the P870 high-performance core released by SiFive in 2023, and adds many new features for data center applications:

P870-D supports the open AMBA CHI protocol, with a single cluster up to 64 cores. Overall up to 256 cores, while the original P870 supports up to 32-core clusters;

SiFive has also added RAS functionality to the P870-D, which can detect errors before problems occur and protect data integrity, helping to prevent downtime and ensure system security. Overall reliability;

In addition, P870-D also contains a distributed and scalable IOMMU (Note from this site: Input-Output Memory Management Unit) to accelerate virtualization device IO.

▲SiFive Performance Core Roadmap

SiFive senior director Ian Ferguson told the foreign media The Register that according to SiFive’s test results on TSMC’s 3nm process, the performance of P870-D is equivalent to ArmNeoverse N2, but its scale is only behind. 3/4 of the total.

SiFive Senior Vice President of Products John Ronco said in a press release:

SiFive brings a clean, modern approach to the AI ​​era with its broad portfolio of RISC-V solutions. The new P870-D enhances our proven high-performance architecture, taking performance, flexibility and scalability to new levels.

SiFive’s complete set of solutions including software, IOMMUs, interrupt controllers and other non-core modules combined with our intelligent processors for AI enable our customers to easily implement AI and data center workloads The most effective performance/power/cost metrics.

The SiFiveP870-D processor is currently sampling to key customers, with final production versions expected to be released by late 2024.
