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.

**Table 1** Performance specification references of the Atlas inference products
Scenario	Total Frame Rate
n-channel 720p (1 ≤ n ≤ 3)	n * 480fps
n-channel 720p (n > 3)	1440 FPS
n-channel 1080p (1 ≤ n ≤ 3)	n * 240fps
n-channel 1080p (n > 3)	720 FPS
n-channel 4K (1 ≤ n ≤ 3)	n * 60fps
n-channel 4K (n > 3)	180 FPS

**Table 2** Performance specification references of the Atlas 200I/500 A2 inference products
Scenario	Total Frame Rate
n-channel 720p (1 ≤ n ≤ 3)	n * 400fps
n-channel 720p (n > 3)	1200fps
n-channel 1080p (1 ≤ n ≤ 3)	n * 200fps
n-channel 1080p (n > 3)	600 FPS
n-channel 4K (1 ≤ n ≤ 3)	n * 50fps
n-channel 4K (n > 3)	150 FPS
