Downclocked my notebook with a single-core Turion processor to only 800MHz. Here are some interesting numbers.

Webkit nightly build r41199 from public SVN. Using Safari 4 beta as the frontend UI.

I probably should have given up on the IE7 test, but I let it complete for personal curiosity's sake. It kept running, and running, and running, and running some more, and.... well, you likely get the point. Anyway, the spread between top (Webkit) to bottom (IE7) roughly equates to about a 30 times JavaScript performance difference on my system when clocked at 800MHz.
