SpacemiT V100: the First Chip Fully Compliant with the RISC-V Server Specification

SpacemiT V100 Xiangshan RISC-V server spec RVA23 DDR5 PCIe 5.0 datacenter

On October 19, 2026, at the 6th RISC-V Summit China in Shenzhen, SpacemiT (进迭时空) and the Xiangshan open-source processor team jointly launched the V100 (“Vital Stone”) — a server-class CPU that the company positions as the first general-purpose compute chip fully compliant with the RISC-V server specification family. Compute, AI and storage server systems built around it were shown at the same time. This is the announcement that moves RISC-V from “embedded and edge” into the machine room proper.

Why “first” is a standards claim, not a marketing line

What makes the V100 notable is not raw clock speed — it is that a whole stack of server specifications has only recently stabilized, and this is the first chip launched against the complete set:

The practical consequence, as the company frames it: a mainstream Linux distribution installs, boots and runs on the platform unmodified — SpacemiT lists openEuler, openRuyi, openKylin, Debian, Ubuntu, Fedora, Red Hat and Rocky. That is the x86-style deployment model (one distro image, many server SoC platforms) rather than the per-chip BSP porting that has defined most RISC-V system work to date.

Microarchitecture: 6 + 40 hybrid cores

The V100 integrates 46 RISC-V cores in a two-tier hybrid arrangement:

ClusterCoresMax clockPer-core throughput
Xiangshan Kunminghu V2R2 (performance tier)62.1 GHzSPECint2006 ≥ 15.0/GHz
SpacemiT X100 (throughput tier)402.4 GHzSPECint2006 ≥ 9.0/GHz

A dual-socket coherent interconnect scales the configuration to 92 cores per server. Press coverage of the launch (Michael Larabel’s report, syndicated via KhanList) adds 12 nm process and 120 W TDP, figures not present on the official product page — treat them as reported, not confirmed by SpacemiT.

Back-of-envelope, our estimate: 40 × 2.4 GHz × 9.0 + 6 × 2.1 GHz × 15.0 ≈ ~1050 aggregate SPECint2006 per socket. This is arithmetic from the official per-core, per-GHz figures — SpacemiT has not published a whole-chip score, and real multi-core scaling will land below the ideal sum.

Memory, I/O and virtualization

Server-grade RAS and security

The V100 implements the full RISC-V server RAS feature set covering CPU, memory, PCIe and interconnect, with on-die temperature sensors monitored by a BMC over in-band and out-of-band firmware management. On security: hardware root of trust, secure boot, key management, lifecycle management, secure debug, trusted computing, and support for mainstream Chinese national cryptographic (guomi) algorithms — a clear signal about its primary market being China’s domestic datacenter and “agent infrastructure” builds.

Product lineage: K1 → K3 → V100

K32026RISC-V AI CPUFirst volume-produced RVA23 chip
V1002026Server-class CPUFirst chip fully compliant with the RISC-V server specification

SpacemiT founder and CEO Chen Zhijian called V100 “the step from end devices to the cloud” for the company, and framed it as RISC-V moving into a “truly deployable, scalable datacenter market.” RISC-V International CEO Andrea Gallo, speaking at the same summit, positioned the architecture as serving both cloud and edge AI. Notably, V100 lands in the same niche as Lanxin’s LX500 (48 cores, 75 TOPS INT8, Lenovo WR5219 G5 in volume production) — China now has at least two RISC-V server CPUs moving from paper to product within the same quarter.

Cold-water check: a 46-core, 12 nm, 52-lane PCIe 5.0 part is a credible first-generation RISC-V server CPU, but it is not chasing current Xeon/EPYC/Arm top-end silicon. The bet here is the standards stack — if one distro image really does boot across RISC-V server platforms, the ecosystem cost curve bends. Benchmark data on real hardware will be the next thing to watch.

2026 年 10 月 19 日,在第六届 RISC-V 中国峰会(深圳)上,进迭时空(SpacemiT)与香山团队联合发布服务器级 CPU V100(Vital Stone),定位为业内首颗完整符合 RISC-V 服务器规范体系的通用计算芯片,计算、智算、存储三类服务器整机方案同步亮相。

“首颗”是标准符合性声明

V100 的关键不在主频,而在于它是第一颗对着完整服务器规范套件发布的芯片:RVA23 Profile、Server SoC 规范、Server Platform 规范、Boot & Runtime Services(BRS,官方称测试全项通过)以及安全模型。落地效果是:主流 Linux 发行版无需定制即可直接安装启动 — 官方列出 openEuler、openRuyi、openKylin、Debian、Ubuntu、Fedora、Red Hat、Rocky。这正是 x86 式的“一个发行版镜像装多种服务器平台”部署模式,取代以往逐芯片做 BSP 的做法。

微架构:6 + 40 混合核

集群核数最高主频单核吞吐
香山昆明湖 V2R2(性能层)62.1 GHzSPECint2006 ≥ 15.0/GHz
进迭时空 X100(吞吐层)402.4 GHzSPECint2006 ≥ 9.0/GHz

通过双路一致性互联可扩展至单服务器 92 核。发布会报道(Michael Larabel,经 KhanList 转载)补充了 12 nm 工艺与 120 W TDP,这两个数字不在官方产品页上,按“报道口径”对待。

粗算(我们的推算,非官方数据):40×2.4×9.0 + 6×2.1×15.0 ≈ 单路约 1050 聚合 SPECint2006。这是按官方每核每 GHz 数字做的算术,进迭时空未公布整芯片成绩,实际多核扩展会低于理想和。

内存、I/O 与虚拟化

RAS 与安全

完整 RISC-V 服务器 RAS 特性覆盖 CPU、内存、PCIe、总线;多位置温度传感器由 BMC 实时监控,支持带内/带外固件管理。安全侧:硬件信任根、安全启动、密钥管理、生命周期管理、安全调试、可信计算,并支持国密主流算法 — 目标市场指向国内数据中心与智能体(Agent)基础设施。

产品谱系:K1 → K3 → V100

型号年份定位里程碑
K12024RISC-V AI CPU首颗 RVA22 量产芯片
K32026RISC-V AI CPU首颗 RVA23 量产芯片
V1002026服务器级 CPU首颗完整符合 RISC-V 服务器规范的计算芯片

进迭时空创始人兼 CEO 陈志坚称 V100 是公司“从端到云”的一步;RISC-V 国际基金会 CEO Andrea Gallo 在同一峰会表示 RISC-V 正在为云端与边缘 AI 提供支持。值得注意的是,V100 与蓝芯算力 LX500(48 核、75 TOPS INT8、联想 WR5219 G5 已量产)落位同一赛道 — 同一季度内,中国至少有两颗 RISC-V 服务器 CPU 从纸面走到产品。
