Why This Matters

SiFive's new BigSky SF-2U870 platform marks a significant step forward in RISC-V high-performance server solutions, offering robust hardware capabilities and compatibility with the latest standards like RVA23. This development enhances the viability of open-source RISC-V architectures in enterprise and data center environments, potentially challenging established CPU vendors. For consumers and the tech industry, it signals increased diversity, innovation, and the growing maturity of RISC-V in demanding applications.

Key Takeaways

Hello you fine Internet folks,

The RISC-V ecosystem is an ever-evolving one especially in the high-performance application class silicon space. We have seen a number of acquisitions and exits in the past year with Ventana being acquired by Qualcomm in December of last year and the wrapping up of operations of Condor Computing. We have also seen silicon being taped out with the most prolific chip being SpacemiT’s K3 SoC with Tenstorrent following suit with their Atlantis SoC along with Akeana taping out their test chip.

But today we are not talking about those companies nor those chips. Today we are talking about a company that has been in the RISC-V scene since the very beginning, SiFive and their new platform, the SiFive BigSky SF-2U870.

Aiming for the Sky

The BigSky SF-2U870 (BigSky) platform consists of:

A standard 19” 2U server

32 P870-D cores running at 2.2 GHz

256 GB of DDR5-5600

64 Lanes of PCIe 5.0 plus 4 Lanes of PCIe Gen 3.0

Support for double-wide GPUs (Up to 450W)
