Performance Specifications

This section describes only the performance specifications of Ascend AI Processors 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 uses a single Ascend AI Processor as an example to describe the performance indicators in basic scenarios. The performance indicators of other resolutions can be estimated in the same way.

In the following table, one channel corresponds to one thread, 720p indicates a resolution of 1280 x 720 pixels, 1080p indicates a resolution of 1920 x 1080 pixels, and 4K indicates a resolution of 3840 x 2160 pixels.

The VPC processing performance is closely related to the image resolution during processing. The maximum resolution of the input and output images is used as the reference resolution. A larger reference resolution indicates a longer processing time and lower performance.
A VPC batch processing API (whose name includes "batch", such as acl.himpi.vpc_batch_crop_resize_paste) allows parallel image processing of multiple VPC hardware units in the DVPP. Therefore, a single channel can reach the maximum total frame rate.
