I only kicked the tires on the discrete GPU.
I have been looking at this now. It seems, according to `turbostat` that one core reaches 3000mhz (indicating turbo is not kicking in), but... see below:
I have https://ark.intel.com/products/97463/Intel-Xeon-Processor-E3... so Turbo should hit 4ghz
I tried this:
https://askubuntu.com/questions/871308/enabling-disabling-tu...
and put a 1 in /sys/devices/system/cpu/intel_pstate/no_turbo and it dropped the cpu frequency from ~2700 to 2200 according to the `turbostate` command. However, when I run i7z it reports a frequency of 3000 (maximum frequency without turbo), which is correct, and a frequency of ~3600 mhz (freq multiplier of 36x, which is one of a possible 40x, 38x, 37x, and 36x turbo multipliers) so I /think/ it is doing the right thing. I am going to assume turbostate is not correctly reporting the frequency using the correct multiplier, but that may not be true.
It is definitely scaling the CPU speed. And, anecdotally, it compiles things very quickly :)
What sort of investigations have you performed?
the only problem is that turboboost does not seem to work out of the box, is it working for yours?
