Compute throughput: 300 TOPS · Rating precision unresolved One photonic-electronic computing card in the jointly developed payload intended for orbital validation. Official Shanghai Science and Technology Commission report gives a 300 TOPS per-card design rating and INT8, FP8 and FP16 support. It does not assign the rating to one precision, disclose card count or establish measured orbital throughput. Planned specification. Included with these qualifications.

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.
