Microsoft has really been putting a lot of focus on improving it with each release. I love reading through the blog articles for each major release, that outline all the performance improvements that were done: https://devblogs.microsoft.com/dotnet/performance-improvemen...
A warning for those not in the know, the performance improvement posts famously give mobile browsers trouble because they are so massive. All because the extent of the improvements is so great (along with the amount of detail the posts go into about the improvements).
And if you look at the PRs for the core, there are Intel people hacking away at the low-level routines too; to make it run better on their latest server CPUs.

Old Note 9, Chrome and Firefox.
Non flagship mobile devices could very well choke on one of those pages, but most newer devices should display these pages with little grief.
