Apple says its new Safari 4 is the world’s fastest browser:
Still the world’s fastest web browser, Safari outraces Firefox, Internet Explorer, and Chrome. On even the most demanding Web 2.0 applications, Safari delivers blazingly fast performance thanks to the industry’s most advanced rendering technologies.
Adrian Kingsley-Hughes at zdnet has tested Safari vs Chrome and IE8, and says Apple’s claims do not stand up to scrutiny. In his tests, Chrome is faster. Unfortunately, he used a different build of Chrome than Apple – 184.108.40.206 vs 220.127.116.11. In addition, he is using a quad core processor, Intel’s QX9770, whereas Apple is using an iMac with a Core 2 Duo processor. Chrome is still work in progress on the Mac, so the results for this are on Vista.
Update: Blogger Luca Filigheddu backs up Apple’s claims with some real-world tests.
