Power draw of gpu

Hi,

I am measuring the GPU power on the TX1 through the INA monitors available in the newer revisions. Would like to know if the 15W limit envelope is statically fixed between the GPU, CPU and Memory or is it dynamic in the sense that if there is no load on CPU then the GPU can boost up to as much as required. Reason I am asking is that in some benchmarks I am using the GPU power goes up to 7 or 8 watt at times. I hope this information can be discussed here. Thank you.

Best,
Trinayan

15W is for whole module, a total limit of all parts.

Any INA monitor to measure memory power? I can only find for VDD_GPU and VDD_CPU. Thanks

No INA for memory power.
