ECCN 3A090 - advanced-computing integrated circuits (Commerce Control List thresholds)

STRUCTURED RESTATEMENT of CCL paragraph 3A090 with the paragraph text quoted verbatim, cross-checked against 91 FR 1684 (spl-bis-2026-01-advanced-computing-case-by-case) which cites the same TPP and DRAM-bandwidth figures. Marked confidence 0.8 rather than higher because it is a lookup site, not the eCFR itself: the authoritative text is 15 CFR 774 supplement no. 1, and the binding determination for any specific part is the exporter's own ECCN classification, not this page. THRESHOLDS, which is the part a supply record needs: 3A090.a covers ICs with 'total processing performance' >= 4800, OR TPP >= 1600 with 'performance density' >= 5.92. 3A090.b covers TPP >= 2400 and < 4800 with performance density >= 1.6 and < 5.92, OR TPP >= 1600 with performance density >= 3.2 and < 5.92. 3A090.c and .d address HBM and other items. The parenthetical note in 3A090.b matters for anyone reading a datasheet: '2 x MacTOPS may correspond to the reported TOPS or FLOPS on a datasheet' - industry convention counts one multiply-accumulate D = A x B + C as 2 operations, so a vendor TFLOPS number is twice the TPP contribution unless stated otherwise. THE PRACTICAL SCOPE POINT for supply records: consumer gaming GPUs generally do NOT meet 3A090 parameters and fall under 3A001 or EAR99, while professional and datacenter parts of the same architecture may. That is why a GeForce RTX 5090 and an RTX PRO 6000 Blackwell from the same generation can carry different export-control status, and why the status must be recorded per part rather than per vendor.
