NEC
NEC designs HPC systems (SX lineage) and integrates NVIDIA platforms for Japanese enterprise and research buyers. A meaningful share of its GPU server volume rides on partner hardware, so treat individual SKUs case by case.
- NEC's NVIDIA-Certified Systems are all PCIe GPU rack servers (Express5800, NX7700x), not HGX baseboard, MGX or NVL72 platforms; no Blackwell-generation NEC system found as of mid-2026
- For its own flagship AI supercomputer (928x A100, 580 PFLOPS), NEC bought Supermicro GPU servers rather than using its own line at scale
- One genuine in-house AI-infrastructure IP: ExpEther, a proprietary PCIe-over-Ethernet GPU disaggregation and pooling technology, commercialized Jan 2026
- Express5800 servers are designed and produced domestically at NEC Platforms plants in Japan
| Model | Platform | Form factor | Cooling |
|---|---|---|---|
| Express5800/R120j-2M Newest certified NEC server: H100 NVL, L40S, L4 (Hopper/Ada, not Blackwell) | PCIe | 2U | air |
| Express5800/R120h-2M A100, T4; NVIDIA-Certified | PCIe | 2U | air |
| NEC AI Supercomputer (internal) 580 PFLOPS, operational 2023; hardware sourced from Supermicro | HGX A100 (Supermicro-built) | 116 servers, 8x A100 each | TBD |
- Several Express5800 and NX7700x models are NVIDIA-Certified Systems (A100, H100 NVL, L40S class, PCIe)
- cotomi LLM available via NVIDIA NIM microservices (June 2025)
- Not on NVIDIA's MGX partner list at Blackwell launch
- NEC Platforms Kofu Plant, Yamanashi, Japan: design, development and manufacturing
- NEC Platforms Otsuki Plant, Yamanashi, Japan
- NEC's credible NVIDIA offering tops out at Hopper/Ada PCIe servers; verify Blackwell availability directly
- Real strategic weight is as a Japan sovereign-AI integrator: cotomi Japanese LLM and the NEDO-backed consortium with SoftBank, Sony and Honda
- ExpEther PCIe-over-Ethernet GPU pooling is NEC's actual proprietary hardware differentiator
- Multi-vendor: also ships AMD Instinct-based supercomputers (QST/NIFS, Nov 2024)
Is NEC an OEM, ODM or integrator for NVIDIA AI servers?
NEC sits in the "Global OEMs" tier of our index. NEC's NVIDIA-Certified Systems are all PCIe GPU rack servers (Express5800, NX7700x), not HGX baseboard, MGX or NVL72 platforms; no Blackwell-generation NEC system found as of mid-2026
Does NEC design its NVIDIA servers in-house?
NEC designs HPC systems (SX lineage) and integrates NVIDIA platforms for Japanese enterprise and research buyers. A meaningful share of its GPU server volume rides on partner hardware, so treat individual SKUs case by case.
