IE8: Acid Test Passes
You’ll be surprised to see that Internet Explorer 8 Beta (8.0.6001.14184) does better on the Acid2 test than Firefox 2 (2.0.0.12) does:

Safari also passes the Acid2 test, but nobody uses it
The results are far worse on the Acid3 test, with IE8 scoring 17% and Firefox scoring 50%, but I believe they are intended. See, when Microsoft releases Beta 2 of their browser, it will definitely pass the Acid3 tests to give the community just that much more shock and awe:

Safari gets 39%, yay?
Ironically, the IE8 website throws an error when viewed with IE8. I guess that’s what they mean by improved standards compliance:

Worse, the Official Microsoft Site prompts to install some nasty, spyware-looking ActiveX control to view the IE8 site:

Congratulations Microsoft, on passing the Acid2, but unfortunately you have a laundry list of things to do, not limited to (a) make it faster and lighter than Firefox, (b) build in good developer tools, (c) get rid of ActiveX, (d) make a more usable UI, or (e) fix your own website to work in IE.
Safari 3 Windows Review, Benchmark
Safari has a new version, and a new platform. The once mac-only web browser has released Safari 3 for Windows XP, backed by claims of UI, performance, and integration superiority. The claims are that it is 2x faster in Javascript and HTML rendering, a claim we plan to test ourselves. Note that Safari, the first time it was launched, took about a minute to start up and froze the screen for that time. Only after that did it open fast.

Javascript Performance Results
So, their biggest claim is Javascript performance, which they show like so:

We’ll combine the overall results from these benchmarks together:
We find that depending how you look at it, Safari can actually be considered 3x slower than IE7, or roughly of equal speed. Here is an overall performance chart, with two columns–one is the raw average score, the other averages the worst-test group (three results) into one result and averages it:

Safari doesn’t break much ground here
Here’s the per-test chart, which shows Safari kicking ass in the first test, losing the next three, tying the fourth with IE, and doing well again on the last test:

Other annoyances
Interestingly, Apple tries to bundle Safari with not one, but three separate Apple products: Quicktime, Bonjour, and Apple Update. On top of that, they break the back-mousebutton click that I’ve become used to using in IE/FF, and use tons of my RAM main memory up. No one sums it up better than Dev Hints who notes that “Safari Isn’t the Beauty That Apple Likes To Claim.” It’s not bad, and it’s getting better, but there are still bugs to be worked out.
