Right now I am on my ancient cheap laptop with some 4 core intel and hard drive noises, the only time it has issues with webpages is when I have too many tabs open for its 4gigs of ram. My current laptop which is a 16 core Rhyzen 7 from about 2021 (x13) has never had an issue and I have yet to have too many tabs open on it. I think you might be having a OS/browser issue.

As an aside, being on my old laptop with its hard drive, can't believe how slow life was before SSDs. I am enjoying listening to the hard drive work away and I am surprised to realize that I missed it.
