Compute throughput: 4 TOPS · Arithmetic precision not specified Historical 2021 SpaceCloud iX5-100 heterogeneous payload design. Preflight supplier specification distributed across CPU/GPU/FPGA/VPU. Precision is unspecified and no in-orbit benchmark is claimed. The host launch is separately corroborated; this is not current aggregate ION capacity. Planned specification · June 2021. Included with these qualifications. Source observation: 2021-06-16. Supporting source ↗Compute hardware: SpaceCloud iX5-100 with AMD CPU and GPU, Microsemi FPGA and Intel Movidius Myriad X VPU Historical 2021 Wild Ride / Nebula payload. Applies to the June 30, 2021 iX5-100 flight configuration, not the separate 2026 iX20 payload. The source does not identify the exact AMD or Microsemi part number or component quantities. The 4 TOPS system design figure is not assigned to any individual chip and is not a measured orbital benchmark. Payload-provider identification of the launched flight computer. Included with these qualifications. Source observation: 2026-10-29. Supporting source ↗Memory / storage: Solid-state storage, capacity unspecified Historical 2021 Wild Ride / Nebula payload. D-Orbit identifies solid-state storage in the demonstrated first iteration. RAM quantity and installed storage capacity are not disclosed.

Technical specifications retain the source’s original units and evidence status. Hardware counts, compute rates and power are not equivalent; launched hardware does not establish demonstrated performance. Supplier counts include suppliers and hosts only, reflect current filters and cover this directory, not the entire market. “No record” means no disclosure captured; it does not mean the work is unawarded. Latest developments use source dates, not routine review or collection dates.
