powermetrics bandwidth stats (M1 Max)
Hi, I am trying to interpret the bandwidth stats from the built-in powermetrics cli tool on M1 Max. For example, I can get output that looks like this: GFX RD             : 7.144 MB/s GFX WR             : 5.154 MB/s GFX1 RD             : 7.108 MB/s GFX1 WR             : 5.155 MB/s GFX DCS RD           : 6.544 MB/s GFX DCS WR           : 6.951 MB/s I have a few questions: What is "DCS"? On M1 Max, there is GFX and GFX1. Is this 2 cluster of 16 graphics cores, each with their own memory controller? In that case, what is "GFX DCS"? I can't find any existing documentation, so hope someone can help to explain this. Thanks in advance!
