SpacemiT, a China-based CPU developer, has introduced the VitalStone V100, a server processor with up to 64 RISC-V cores, reports Heise Online. While the CPU is aimed at modern workloads, the single-thread performance of the processor is comparable to outdated Intel Xeon and AMD Opteron processors.
SpacemiT's VitalStone V100 processor is largely based on the OpenC910 project design, which is already used by Alibaba's T-Head Xuantie C910 processor. The X100 4-issue 12-stage out-of-order cores in the VitalStone V100 were developed in-house by SpacemiT. They are compliant with the RVA23 core specification and support 256-bit vector processing, standardized hypervisors and IOMMU (input-output memory management units), protection against certain side-channel attacks like Spectre or Meltdown, and RISC-V Boot and Runtime Services (BRS), which define how processors boot and interface with firmware and operating systems. The processor is made on a 12nm-class process technology and its maximum frequency is 2.50 GHz.
