JPEGE Performance Specifications

Performance Specifications

This section describes only the performance specifications of the AI processor of each product, which may differ based on the memory and CPU configurations of the respective product. For details about the product performance specifications, see the official descriptions at the Ascend community.

This section takes a single NPU 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.

In the following table, one channel corresponds to one thread, 1080p indicates a resolution of 1920 × 1080 pixels, and 4K indicates a resolution of 3840 × 2160 pixels.

On the Atlas A3 training products/Atlas A3 inference products, an NPU has two devices, and the maximum specifications can be reached only when the two devices work in parallel.
