NVIDIA designs different SKUs for each export tier, creating a cat-and-mouse with Commerce Department rules

After the October 2022 chip export controls, NVIDIA created the A800 and H800 as China-specific variants with reduced interconnect bandwidth to comply with BIS thresholds. When BIS updated rules in October 2023 to close this loophole, NVIDIA began designing yet another variant. Each rule revision triggers 6-12 months of chip redesign at NVIDIA, during which Chinese customers stockpile the current-generation chips. This creates a permanent lag where export controls are always one chip generation behind the market. This persists because the controls use static performance thresholds (TOPS, bandwidth) that a chip designer can engineer around, and BIS lacks the technical staff to write rules that capture capability without using easily-gamed numeric thresholds.
