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.
Performance Specifications (
Atlas inference product
)
The following performance data is based on executing acl.rt.synchronize_stream once after 64 asynchronous media data processing tasks are delivered to a stream, and the host server is configured as: Intel(R) Xeon(R) CPU E5-2680 v4@2.40 GHz as the CPU frequency, with 14 CPU cores.

A VPC batch processing API (whose name contains "batch", for example, acl.media.dvpp_vpc_batch_crop_async) allows the parallel image processing on multiple VPC hardware units in the DVPP. Therefore, a single channel can reach the maximum total frame rate.
Performance Specifications (
Atlas training product
)
The following performance data is obtained by calling the acl.rt.synchronize_stream API once after 10 asynchronous media data processing tasks are delivered to a stream.
- For non-8K images, the performance specifications in basic scenarios with a single device are as follows (one channel corresponds to one thread):
