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.

**Table 1** Performance specifications of the Atlas inference products
Scenario with YUV420 8-Bit Input	Total Frame Rate
n-channel 1080p (1 ≤ n ≤ 8)	n * 128fps
n-channel 1080p (n > 8)	1024 FPS
n-channel 4K (1 ≤ n ≤ 8)	n * 32fps
n-channel 4K (n > 8)	256 FPS

**Table 2** Performance specifications of the Atlas 200I/500 A2 inference products
Scenario with YUV420 8-Bit Input	Total Frame Rate
n-channel 1080p	256 FPS
n-channel 4K	64 FPS
