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.

The performance specifications of JPEGD are based on hardware decoding performance. JPEGD hardware decoding does not support the image decoding with three SOS markers. For image formats not supported by hardware, software decoding is used. The software decoding performance for reference is 1080p at 15 FPS. If the output image decoded by JPEGD involves rotation, the performance is lower than the reference values of software decoding. For example, the performance is lower than 15 FPS for 1080p images.

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

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

Scenario	Total Frame Rate
1-channel 1080p	128 FPS
n-channel 1080p (n ≥ 2)	256 FPS
1-channel 4K	32 FPS
n-channel 4K (n ≥ 2)	64 FPS

Performance Specifications (Atlas Training Series Product)

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

Scenario	Total Frame Rate
n-channel 1080p (1 ≤ n ≤ 16)	n * 128fps
n-channel 1080p (n > 16)	2048 FPS
n-channel 4K (1 ≤ n ≤ 16)	n * 32fps
n-channel 4K (n > 16)	512 FPS
