The Acid3 test (here) tests a browsers Javascript rendering ability in terms of being standards-compliant, for a reference Webkit scores 100, Opera scores 83, Firefox 3 scores 71, IE 7 scores 12, but you just get a mess (seen here), and Google Chrome (which uses the Webkit rendering engine (don’t confuse this with the browser “WebKit“, read more about webkit here) and a new javascript engine called V8-which boasts speed to kill, produces a 73 on the Acid3 test. Not bad considdering it’s the fastest to complete the test, but clearly Opera and WebKit (the browser).
@UPDATE- 9:35P
after doing some Google searching I’ve discovred that Google Chrome has scored from 61/100 to 78, this test is supposed to be repeatable, however it seems there’s some user-biased module to Chrome. My finding was that Chrome scored 73. That’s all I can say for sure.
