ZXO GB300 / Proposed Flagship Configuration
Concept 01 — 2026-10-28

Status: exterior design concept and engineering targets. This is not a qualified shipping configuration or a claim of NVIDIA/OEM certification.

Core platform reference
- NVIDIA GB300 Grace Blackwell Ultra Desktop Superchip.
- One 72-core Grace Arm Neoverse V2 CPU and one Blackwell Ultra GPU.
- 748GB coherent memory: 252GB GPU HBM3e plus 496GB CPU LPDDR5X. The two memory types have different bandwidths.

ZXO flagship integration targets
- One additional RTX PRO 6000 Blackwell Workstation Edition GPU with 96GB GDDR7 ECC, subject to the selected OEM platform, power sharing and cooling approval. Its memory is separate from the GB300 coherent-memory pool.
- Four Samsung 9100 PRO 8TB M.2 2280 PCIe 5.0 x4 NVMe SSDs: 32TB total raw nominal capacity. This is a proposed integration target, not confirmed whole-system compatibility or an officially qualified capacity limit.
- Ubuntu Arm64 with compatible NVIDIA AI developer tools and supported software versions.
- GB300-qualified OEM cooling, power management, networking and firmware as the integration foundation.

Storage qualification
8TB SSD clearance, D5 thickness, heatsinks, thermal pads, slot power, firmware and operating-system compatibility must be checked on the actual platform. Slot generation and topology vary by OEM. Formatting, system reservations and RAID reduce usable capacity. With two 8TB system SSDs mirrored and two independent 8TB data SSDs, nominal logical capacity is approximately 24TB before formatting.

Power and mechanical integration
NVIDIA lists a 1600W reference-system power figure and a 20A circuit requirement. This does not establish that any OEM system can run the GB300 and an additional 600W GPU simultaneously at their individual maximum power settings. Exact power allocation and electrical requirements must be confirmed by the system vendor.

Illustrations show proposed exterior, rear I/O and service features, not CAD drawings or a validated internal layout. Final dimensions, component fit, storage, software, cooling, acoustics, availability and warranty remain subject to OEM sourcing and engineering validation.
