Safari 5 for OS X, Firefox 9 for Windows 7 crowned victors of browser benchmark battle
Tom's Hardware has been running its meticulously detailed Browser Grand Prix since early 2010, and today it has crowned two new winners: Firefox 9 won in the latest Windows 7 Ultimate tests, while Safari 5 was the top browser for OS X Lion.
Context & Ripple Effects
Performance claims have been contested across browser generations: a 2009 Safari result was followed by a challenge to Apple’s Safari 5 speed claim. The latest tests split the result by operating system rather than producing a single cross-platform leader.
Firefox enters the Windows 7 result after IE9 growth on Windows 7 highlighted Firefox’s market-share pressure, while Safari’s win is confined to Apple’s OS X Lion environment. That makes benchmark leadership a platform-specific competitive asset, not a universal verdict.
First-order effects
- Firefox 9 gains an independent performance credential for Windows 7 users at a point when IE9’s growth had put Mozilla under pressure.
- Safari 5 gains the corresponding OS X Lion credential, reinforcing Apple’s browser performance position within its own desktop platform.
Second-order effects
- Microsoft’s IE9 and other Windows browsers face a clearer performance comparison against Firefox 9, making speed a more visible basis for Windows 7 user choice.
- Browser vendors have an incentive to optimize for the operating systems where tests are run, since separate Windows and OS X leaders weaken claims of one browser being fastest everywhere.
Third-order effects
- If operating-system-specific results continue to diverge, browser competition will be shaped less by a single benchmark crown and more by each vendor’s ability to tune software to its host platform.
- The recurring contest between benchmark claims and counterclaims points toward performance measurement becoming a continuing marketing and product-development battleground rather than a settled ranking.
The trend: Browser performance competition is fragmenting by operating system, with benchmark leadership increasingly tied to platform-specific optimization.
