At least on Linux, any performance counter used by VTune is also available via Linux perf events.
It's just that VTune is uniquely good at presenting the info and guiding the performance analysis.
The only comparable-quality tool I've used is Nvidia's NSys, but obviously that's not focused on x86.
- pjmlp 1y agoDoes Linux perf also show the micro opts and other low level CPU stuff that VTune also allows to dig into? Also the graphical tooling, flame graphs aren't really the same.
