SunSpider JavaScript benchmark and ACID 3 compatibility charts - Firefox 3.0 RC 3 and Opera 9.50 added

Time to add Firefox 3.0 RC 3 and Opera 9.50 to my SunSpider JavaScript benchmark and ACID 3 compatibility charts. How do these new browsers compare to the rest?

SunSpider JavaScript benchmark

This latest run of the SunSpider JavaScript benchmark was carried out on the same hardware and software platform as previous tests (to make sure nothing had changed we re-ran some of the browsers to check that we got the same results).

Here are the results:

[poll id=308]

This is the first time that I've not seen a release of Firefox 3.0 being faster than the previous release - the speed of Firefox 3.0 RC3 is virtually identical to that of Firefox 3.0 RC1 (within the tolerances of the test at any rate). On the other hand, Opera 9.50 final shows dramatic improvement over the betas. However, Opera has a long way to go to catch up with Firefox and Safari.

ACID 3

I also took the opportunity to put each browser up against the ACID 3 CSS compliance test.

Here are the results:

Opera 9.50 final takes the crown, scoring an 83.

Thoughts?
