Browser Comparison - Acid 3 Test
Posted by Joeb on March 14, 2008
So, as requested, I decided to compare the beta’s of all the latest browsers using the Acid 3 test with somewhat surprising results…Below you will find screenshots of the results from IE8 Beta 1, Firefox 3 Beta 4, & Opera 9.5 Beta.
Internet Explorer 8 Test Result:
Firefox 3 Test Result:
Opera 9.5 Test Result:
As you can see - IE8 fails miserably! It initially only gets 10/100, but after a few seconds it increases to 17/100, which I find odd. Though admittedly IE8 is intended for developers to begin getting their pages compatible with IE8. Opera 9.5 also fails the test, though with a more respectable 60/100, which increased from somewhere around 47 after about a second or so.
Finally, Firefox 3, which scores 67/100 is the only browser I tested which doesn’t have the word “fail” on the end result, though I don’t think that counts as a pass because it didn’t score 100.
For what it’s worth, the end result should look like this reference rendering (as provided by acidtests.org).

I think it’s interesting how each browser score is the same no matter what OS it is installed on, unless I’m mistaken. Were all of yours on Vista?

Yes all tests were on Vista

Today I tried with Safari 3.1: it gains a result of 75/100!

Apparently later builds of Opera get 100%, later builds of Safari get 98% and Firefox 3.0b4 get 75%
Not able to test that claim though, as I don’t have these builds (Firefox the exception)

Opera 9.5b2 now gives 78/100.
