What is IOAccelMemoryInfoCollector?

IOAccelMemoryInfoCollector is a diagnostic process tied to GPU memory.

What is IOAccelMemoryInfoCollector?

IOAccelMemoryInfoCollector watches and records how your GPU memory is used. It tracks how much video memory is in use, which processes are using it, and how memory is split across different GPU tasks.

What does it collect?

• GPU memory use per process
• Video memory pressure figures
• Texture and buffer memory use
• GPU memory fragmentation data

This data feeds Activity Monitor's GPU tab and helps Apple find GPU memory problems across macOS.

Does it affect GPU performance?

No. It reads memory figures from the GPU driver without getting in the way of GPU work.

Should you worry?

No. It is a normal macOS diagnostic process for keeping track of GPU memory.
