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!
