I wrote a dead simple bash script that starts up Firefox, Safari and Chromium and samples cumulative cpu time every 5 seconds. All browsers are set up without any extension to open “www.google.it”.

OS: Mac OSX Snow Leopard Hardware: Macbook Pro 13″

Here is the output

cpu time after 10 seconds (startup)
safari 03.25 vs firefox 01.59 vs chromium 1.09
cpu time every 5 seconds (minus startup)
SAFARI | FIREFOX | CHROMIUM

Do you see where this is going ? The same thing happens on every website, when it comes to idling and being gentle on cpu Safari always wins. The difference becomes N times bigger if you consider keeping N tabs opened. This is why I’m a Safari user (next time someone asks, ctrl-c/ctrl-v).
