Chromium take up too much CPU processing power on Linux compared to Windows

I have a Dell Inspiron 15 7579 2-in-1 laptop.

Any chromium-based browsers on any Linux distro are all unnecessarily taking up too much CPU processing power. I pressed shift+esc on both Windows and Linux within the browsers and I found that Brave was taking up way too much CPU processing power compared to Windows. So I compared two websites Benchmark Your Graphics Card On Linux and WhatsApp Web

Idle: 1-4 Scrolling: 30-40

Idle: 0 Scrolling: 30-60

Idle: 0-3 Scrolling: 18-48

Idle: 17 Scrolling: 140-160

Idle: 0 Scrolling: 153

Idle: 2-5 Scrolling: 110

So I am not too sure why on Linux Chromium-based browsers are taking up more CPU processing power compared to Windows, if anyone knows what is going on I would love to know. Thanks
