You're right. Chrome spanks the crap out of any CPU I use it on!
Really, I read this and laughed. Plenty of people are buying current i7 and i9 CPUs for "gaming" with tiny GPUs and probably spending way more time in a web browser than any other app, hands down. Many of them will use integrated graphics for their entire life spent plugged in and doing whatever.
If you are buying an i7/i9 CPU for any scientific or heavy lifting, non-gaming purpose then you are already doing it wrong. But most consumers don't read benchmarks, they buy what's available. And cheap. Cheap helps a lot.
Instead of laughing out loud, I suggest you brush up on English comprehension. 'Gaming' wasn't mentioned by the poster I quoted. They mentioned MS Office applications, web browsing and photoshop.
Gaming is obviously one of the most popular use cases of a high end CPU, as some of these games can actually leverage a benefit from a high end CPU, compared to a mid - range one.
You mention "scientific or heavy lifting, non-gaming purpose" type software. I agree that it's obvious, even to a small child, that such tasks are either best suited to cloud compute, or a Xeon/threadripper based workstation solution.
Again, brush up on your reading comprehension, it's a skill you'll find useful to not put yourself in embarrassing situations.
