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, 1080p indicates a resolution of 1920 x 1080 pixels, and 4K indicates a resolution of 3840 x 2160 pixels.

Performance Specifications (Atlas 200/300/500 Inference Product)

The following performance data is based on executing acl.rt.synchronize_stream once after 10 asynchronous media data processing tasks are delivered to a stream.

**Table 1** Performance specifications of the Ascend AI Processor on the Atlas 200/300/500 Inference Product
Scenario	Total Frame Rate
n-channel 1080p (1 ≤ n ≤ 5)	n * 4fps
n-channel 1080p (n ≥ 6)	24 FPS
n-channel 4K (1 ≤ n ≤ 5)	n * 1fps
n-channel 4K (n ≥ 6)	6 FPS

Performance Specifications (Atlas Training Series Product)

The following performance data is based on executing acl.rt.synchronize_stream once after 10 asynchronous media data processing tasks are delivered to a stream.

**Table 2** Performance specifications of the Ascend AI Processor on the Atlas Training Series Product
