Google Chrome 2 is 20% faster than Chrome 1 in physical speed tests
On Betanews' new physical test platform for Windows-based Web browsers and operating systems, whose construction was completed Friday, our latest tests show that Chrome 188.8.131.52 was 20.4% faster than Chrome 184.108.40.206, in independent benchmarks other than V8 related specifically to speed. Our adjusted performance score for Chrome 2 on our new platform was 21.4% better than Chrome 1, relative to the performance of Microsoft Internet Explorer 7 on the same system.
For the past few months, we'd been testing Web browser performance on easy-to-manage virtual machines. Our move to a physical platform did change our index numbers with respect to Windows Vista, but it changed them fairly proportionately to one another.
Microsoft Internet Explorer 7 ran a little faster in Windows Vista than the IE7 we measured on a virtual system. That should be no surprise to anybody. Naturally, nothing is slower than IE7, which is why we still use it as our index system. But as we verified by repeating the test circumstances from scratch, IE7's speed did jump more than the other browsers in our test.
But not by much. While our initial performance index score for Internet Explorer 8 showed it easily doubling IE7 with room to spare, our reset score was still double that of IE7, with about 215% the speed of its predecessor. IE8's physical index score is 2.03, reflecting a much better SunSpider score for IE7 on the physical platform -- its string processing score is especially higher.
All the other browsers in our test are, as we said, proportionately lower, but with variations less-than-slight enough to justify our having moved our test bed to a physical platform. In our latest tests, Apple's Safari 4 beta registered a score of 14.12 -- meaning Apple's latest browser performs over 14 times better than Microsoft's earlier browser. Divide that score by 2.03, and you'll see how much better performer Safari 4 is than IE8.
After restarting our test matrix fresh on a physical Vista platform, we're adjusting the scores for Firefox browsers to account for the faster IE7. But our latest battery of tests still verify that of Mozilla's three development browsers, the one the public's testing right now -- Firefox 3.5 Beta 4 -- remains the fastest. We've noted the "Beta 5" designation has recently been removed from the 3.5 Beta 5 "Shiretoko" track, indicating a likely move to Release Candidate status. But while Beta 4 posted a revised index score of 8.49, the latest daily build of the private tests of 3.5 posted a 7.47 -- a score we verified by repeating the circumstances. And the latest daily build of Firefox 3.6 Alpha 1 "Minefield" followed behind at 7.25.
We'll be following the suddenly resurgent arena of competitive Web browser development on our physical platform from now on. Our machine uses a Gigabyte GA-965P-DS3 motherboard with an Intel 965 chipset, running a 2.40 GHz Intel Core 2 Quad Q6600 processor with 3 GB of DDR2 DRAM. Our display adapter is an Nvidia GeForce 8600 GTS, and our physical Vista platform is running an Nvidia brand driver.
