* Textures (the same as the ALU but for sampling textures, this is its own debated hardware unit) * 'ALU limit/Utilisation' and indiction of how close the application is getting to fully staturing the raw math compute power of the gpu (most apps will be limited on other factors and not come close to this) This is also broken down by data type (FP16, 32 etc) * 'Occupancy' how many of the gpu threads are active (this is the value that is used by activity monitor) The GPU metrics you can get are in fact quite a bit more detailed than most CPU metrics.
From here you can capture information about the load on your gpu in many different ways at a high resolution including. If you want to do that then you should look into the tools provided in Xcode (you can download this from the App Store for free) when opening Xcode you can in the menu bar click 'XCode -> Open Developer Tools -> Instruments' this opens a tool you can use to inspect in much much more detail the usage and behaviour of apps running on your system.įrom here apple provide some (useful ish) templates but you can build your own templates. it does not indicated the real usage of your gpu. From my expirance the active monitor seems to indicate the maximum number of congruent thread groups that were active during a given priord (even if they were only active for 1ms if all groups were in use then it will show 100%). But for a range of reasons its even more hand wavy than the cpu. The % GPU load indication is a very bad approximation of usage (just like the % value for a cpu).
