Will Power Bi / Query support multithreading in the future?

As captioned, buying a new PC, wonder if I need a higher core count CPU for future updates. Many Thanks

    Power BI already uses multiple cores.  If you want to splurge, get more memory.

    HI nascaline,

    As lbendlin said, current power bi already enabled multiple threads feature. (e.g. parallel loading)

    You can direct use these features if your device existed enough resources. For performance reasons, I'd like to suggest you use the 64-bit version instead 32-bit version. (notice: 32-bit version has 4G limit on memory resource usage)

    BTW, you can also take a look at the following blog about tips and tricks to improve power bi performance:

How exactly are the processes distributed to the threads?

Is it that rendering is executed on one thread and e.g. queries on a separate thread?

That is my assumption. I have a huge report and when I change the page there after longer modeling I actually see only load on one core.

So if queries make up 90% of the performance usage and e.g. rendering only 10% you don't notice much of the multithreading.

I have an i5 11600 and 64GB RAM.
It doesn't run that well, especially after prolonged use it feels like an engine limitation.
