DeviceQuery shows that the maximum core frequency of 3080 is
GPU Max Clock rate: 1905 MHz (1.90 GHz)
On the other hand, I did a test with Nsight Compute for a program with a bunch of kernels. As you can see in the picture below, the cycle numbers and kernel times are shown (output of raw summary). I then added another column which shows the frequency which is 1/(time/cycles).
The numbers show that the frequency is around 1400 MHz and that is similar to the device specification in techpowerup (base clock). However, I have a couple of questions:
1- Does that mean the 1.9 GHz is an overclock frequency or that can be achieved automatically by the firmware depending on the load?
2- I see the frequency is 39 MHz for one kernel with duration of 1.8 ms and 72k cycles. That sounds weird compared to others. Is there any way to get further information about that?
