Nvidia started offering the A100 replacement, the A800, to Chinese customers. The A100 is based on the Ampere architecture and is widely used in AI, data analytics and HPC. The United States introduced a new policy on export restrictions last month, and the A100 was included in the list of export restrictions. The A800 has the same computing performance as the A100, but with narrower interconnect bandwidth and lower data rates than egress limits. Nvidia says the A800 is compliant with U.S. government export controls and cannot be programmed to exceed export control speeds. Nvidia expects high demand for the A800 chip; the company will start making offers in China as soon as Wednesday. Shipments are expected to begin in the next few weeks. The transfer rate of the A100 reaches 800 GB/s, and the A800 drops to 600 GB/s, which will have a huge performance impact on supercomputing.
