Performance Specifications

This section describes only the performance metric reference data of AI processor corresponding to each product. The performance specifications vary according to the memory and CPU configurations of each product. For details about the performance specifications of each product, see the official description on the Ascend community.

This section takes a single device as an example to describe the performance specifications in basic scenarios, as shown in the table below. The performance at other resolutions can be estimated in the same way.
