To comply with U.S. stipulations, Chinese enterprises received an adjusted version termed the H800 or A800, primarily distinguished by reduced on-device interconnect velocities.

The U.S. Government recently introduced a trade stipulation barring NVIDIA from vending specific models, including the H100, H800, A100, A800, L40, L40S, and RTX 4090, within the Chinese domestic sector. The list also encompasses advanced AI chips like the "Hopper" H800 and "Ampere" A800. It's noteworthy that the H800 and A800, designed exclusively for China, embed hardware-driven performance decrement, aligning with the AI processor constraints established by the U.S. However, their inclusion indicates Chinese users might have discovered methods to counteract these limitations or are securing them in amplified volumes to match the aspired output levels.

Intel and AMD chip sales may experience similar constraints. Foreseeable regulations might further obstruct the transaction and shipment of semiconductor production apparatus to China by corporations such as Applied Materials, Lam, and KLA. Nvidia, foreseeing such impositions in August, predicted these might not drastically affect immediate financial outcomes but acknowledged potential enduring implications. Nvidia said on Tuesday in an SEC filing that the restrictions apply to the company’s A100, A800, H100, H800, L40, L40S, and RTX 4090 chips. It also said that it affected entire systems sold with those chips, including its DGX and HGX systems. Nvidia said the restrictions may hurt its ability to complete development of new products on schedule.
