When testing SunSpider, Chrome v220.127.116.11 scored 919.2ms on the laptop, and 1864.2ms on the desktop. Chrome v18.104.22.168 scored 583.6ms on the laptop, and 1323.4ms on the desktop. The laptop score was 36.6 percent faster, and the desktop was 29 percent faster.
Running both versions of Chrome through Dromaeo came up with similar results. Keeping in mind that the higher number is better for Dromaeo's tests, the older Chrome scored an overall 113.25 runs/s on the laptop. The newer one hit 139.90 runs/s, an improvement of 23.5 percent. The desktop results were the inverse of the laptop's.
Where the SunSpider results showed greater gains for the new Chrome on the laptop, the Dromaeo desktop tests showed an improvement of 33.8 percent. Chrome v22.214.171.124 hit 146.63 runs/s while v126.96.36.199 scored 196.29 runs/s.
Also new in this version of Chrome is the F11 hot key to toggle full screen mode, which drops all hints of the browser frame except for the scroll bars--but only if they're appearing on that site in standard mode. There's also a new form autofill under Options in the Tools menu, and users can selectively remove thumbnails from the New Tab landing page.
