Which OS are you running and which browser? We've optimized for many common browsers/OS combos but have clearly missed yours (nothing to do with your specs).
As a counterpoint, Ryzen 7530U + 16GB here and with Linux+Firefox the page generates a fairly constant 25% CPU load.
So while clearly heavy for what is essentially a few streaming counters, it's not a system killer.
Latest stable Debian 12 with latest stable Firefox 120. Wouldn't really call it an exotic setup...
Runs quite smoothly on my cell phone.
To be fair, this doesn't qualify as generic browsing. It's more like a CGI sequence from a remake of WarGames.
