Benchmarking the New Wave of RISC-V Server Chips

The open ISA goes to work

RISC-V spent a decade as an academic curiosity. This year, three vendors shipped production server processors on the open ISA — and cloud providers are actually deploying them.

The numbers

On integer workloads, the best RISC-V parts now land within 15% of comparable ARM designs. Where they shine is cost: without ISA licensing fees and with aggressive chiplet strategies, price-performance beats x86 by up to 40% on scale-out workloads like web serving and CDN edge nodes.

The software gap

The silicon is ready; the ecosystem is catching up. JIT compilers, vector extensions, and observability tooling still trail ARM by roughly two years. For greenfield cloud-native workloads, that gap is manageable. For legacy enterprise software, it remains a dealbreaker.

Bottom line

RISC-V in the datacenter is no longer a question of if. The only question is which workloads move first — and our testing says the edge is already moving.
