Web Browser Grand Prix: Chrome 20, Opera 12, Firefox 13

How do the latest Windows 7-based Web browsers stack up? Chrome and Firefox each have three wins under this operating system; can one become our champion? Or will Opera clean house here, as it did under Windows XP? We set up a new test system to find out.

DOM And CSS Performance

DOM

Since Dromaeo is still not playing nicely with the WebKit-based browsers under Windows, we have to bring out Acid3. All five Web browsers pass this conformance test scoring 100%, so we're using the completion time as a stand-in performance test. If Dromeao begins to work with WebKit-based browsers on Windows again, we'll bring it back into the fold.

Safari takes the lead at a steady 0.31 seconds. IE9 earns a second-place finish, followed closely by Chrome. Firefox places fourth and Opera, which consistently dominates Mozilla's Dromaeo DOM test suite, finishes last.  

CSS

Composite Scoring

The CSS composite is the average of Microsoft's Maze Solver CSS3 benchmark and Andy Edinborough's CSS Stress Testing and Performance Profiling bookmarklet applied to a copy of the Tom's Hardware homepage hosted from our local Web server.

Safari steals the show, coming in first place at just 3.68 seconds. Chrome 20 is the second-place finisher, followed by IE9 in third place. Opera 12 places fourth, with Firefox 13 coming in last place with a time of more than 35 seconds.

Drill Down

The charts below contain the results of Maze Solver and CSS Stress Testing & Performance Profiling.

Microsoft Maze Solver

As usual, Firefox does extremely poorly in Microsoft's Maze Solver CSS3 benchmark. But Firefox also snags the win with the CSS Stress Testing & Performance Profiling benchmark on every site we apply it to. Opera, which always earns high scores in Maze Solver, has the worst times in the CSS2 test. Only Safari exhibits superior performance in both metrics.

    1.what the benchmarks dont show is that in Firefox , if a tab has a heavy page with a lot of CPU intensive workload, the complete browser UI starts stuttering. That means the browser UI is on the same thread as the page loading.

    2. in the 40 tab test, try working in a tab during the loading of the 40 tabs. you will find lots of difference between browsers. FF hangs, Opera and Chrome remain fluid.

    3. how about a test where a browser is using 1GB+ RAM and you are trying to open/close tabs. Then see the UI responsiveness. most browsers can easily handle 800MB RAM. but which browser easily handles 1.2GB+ RAM ?

    IE9 does so good on HTML5 HWA accelerated benchmarks because its able to offload more of the processing to the GPU.
    i tested this and found that during a HTML5 benchmark, IE9 had the least CPU usage, and most GPU usage amongst all the browsers.

    How many firefox users dont use ADblockPlus ? very very less.Also ABP developer is a regular contributor to the Firefox source code.
    maybe you should do a few memory benchmarks with ABP installed just to realistically judge what 99.99% of FF users go through.

    i won't ever use a browser a browser WITHOUT AD BLOCK Plus. (ABP)

    ABP works wonderful on Firefox, i RARELY see any ad. While I have used ABP on Chrome BUT its doesn't block half the ads.
    I know its Not Google's fault, its just that ABP developers are putting more effort with Firefox.

    So for me, Firefox > Chrome.

    @mayankleoboy1: 1+2) Interesting, I'll be looking for that next time 3) That would require a different workload for each browser.

Besides, that would give FF an unfair advantage.

    MSI afterburner for GPU. windows task manager for CPU.

    i sent a mail regarding this to Chris. but maybe i sent it too late for this article...

    if you open multiple tabs together in chrome, it can use each CPU core for each tab. so if you have a quad core, and you open 4+ tabs together, the CPU usage will be 100% (using all 4 cores) during the tab loading time.
    but if you run 4 instance of dromaeo in 4 tabs, the CPU usage is still 25% (using only 1 core).
    so chrome is not completely multiprocessing.

    in IE10 beta, if you run 4 instances of dromaeo benchmark in 4 tabs, it uses all the for cores. so we can expect better multiprocessing from IE10 and win8 :)

    @mayankleoboy1: I got that email yesterday or the day before, this article was completed a few days before that. Sorry, my inbox usually gets a few pages deep after a doing long benchmark-heavy article.
    Is Dromaeo (the DOM portion) working in Chrome for you? I could not get it to finish in Chrome or Safari on any of my Windows machines.

    i ran the javascript benchmark that ran fine. Didnt run the DOM benches.

    BTW, i run chrome dev version. so that could make a difference.
