Low light performance

[slat]

With the rumored specs of the Canon R5 mark ii will or should it have better low light performance than the R6 mark ii?
I read an article recently that said high MP cameras don't have as good of low light performance as lower MP cameras.

When all else is equal that article would be correct.
