Google's Chrome browser is outperforming the latest "stable" builds of both Firefox 3 and Internet Explorer 7 in the popular Acid3 test. The Acid test, for those who do not know, tests how well a browser complies with a given set of Web standards. While all three browsers pass the Acid2 test, Chrome currently clocks in at 78 out of 100 on Acid3, while Firefox and IE7 stand at 71 and 14 respectively. The only release quality build to beat Chrome is Opera, which scores an 83.

Even though Google has the stable builds edged out, we have to remember that Chrome is still in development, where it is topped by a number of other "unstable," development builds, including Firefox 3.1 Beta 1 (85), Opera (91), and Safari 4 (100). It is interesting that the Safari 4 Developer Preview performs so much better than Chrome, given that they are both built on Apple's WebKit framework.

Whenever a new browser or an update to a browser is released, one of the first things that techies tend to look at is how it fares on the Acid test. The latest iteration of the test, Acid3, is the hardest yet and no "stable" browser builds have achieved a 100 out of 100 on the test, although the Safari 4 Developer Preview has.

Passing the Acid3 test is an important goal for browser developers and it's great to see that Chrome is performing so well on its first attempt.

Update:
A reader, Benjamin, writes in saying that under Vista SP1, Chrome shows scores ranging from 74 to 79 on the Acid3 test. Running it again right now, the test showed a score of a 79. Some of the initial variability could have been due to the servers for the Acid3 test being hammered as a result of Chrome's release.
