Open-source software and open-standard architectures to accelerate next-generation datacenter AI compute

Today at the AI Infra Summit, SiFive, Inc., and AMD showcased a demonstration of AMD ROCm™ (Learn more) running on SiFive’s recently announced BigSky Datacenter Development Platform.

In a demonstration-only system, the companies showed the ability to run the modern Gemma4-E2B LLM model using ROCm 10.0 on SiFive servers powered by the SiFive Performance™ P870-D CPUs acting as the head node, and AMD Radeon™ AI PRO R9700 GPUs driving the inference offload.

This collaboration brings together the best of open source software, the AMD ROCm ecosystem, and the best of RISC-V open standard architectures to enable next-generation datacenter AI compute. The two companies will continue to evaluate optimization of ROCm on RISC-V powered servers, aiming to speed up processing times and enable even more acceleration use cases and larger models in the future.

“We are pleased to collaborate with AMD to bring the ROCm open software ecosystem to our BigSky datacenter development platform,” said Matt Langman, SVP, Datacenter at SiFive. “By combining the leading open standard architecture with their open-source software, we are enabling hyperscalers and developers to run advanced AI workloads seamlessly on RISC-V. This is another pivotal milestone as we work to accelerate the adoption of RISC-V in the datacenter.”

“ROCm’s open-source foundation enables developers to bring accelerated AI workloads to a broad range of systems,” said Ramine Roane, corporate vice president, AI software product management, AMD. “This demonstration with SiFive is an early step in enabling developers to explore ROCm-based AI acceleration on RISC-V host platforms.”

To see the demo in person, stop by SiFive’s booth inside the RISC-V International Pavilion at the AI Infra Summit this week, taking place September 15–17, 2026, at the Santa Clara Convention Center in Santa Clara, CA.

The SiFive BigSky SF-2U870 is designed explicitly for advanced software porting, workload tuning, and validation testing to foster ecosystem enablement. Hardware specifications include:

• 32 P870-D cores operating at 2.0 GHz
• 256GB DDR5-5600 memory
• 4x PCIe® Gen5 x16 (64 lanes) and PCIe Gen3 x4
• 2x 7.68TB U.2 NVMe SSD
• 10/25Gb OCP 3.0 NIC

The platforms are available today. Interested parties should contact SiFive sales for more information.
