Earlier this week Microsoft cast shade on its web browser rivals, benchmarking the energy efficiency of Edge, Chrome, Firefox and Opera on a Microsoft Surface.
Perhaps predictably, Microsoft’s new-to-market browser performed best on a Microsoft Surface running the Windows operating system.
Attacking Microsoft’s lack of transparency in its failure to fully release its methodology saw Opera run a test of its own, unable to copy Microsoft’s conditions.
Opera said on its blog: “[The Microsoft test was followed by an] extensive blog post and obviously a huge PR effort, and it was argued that the test showed that Edge beats Firefox, Chrome and Opera.
“Like most other engineering teams, we love it when someone picks a fight. If we get beaten in a test like this, we consider it a bug.”
Opera, with a naive ad blocker and power saver enabled, lasted longer than Edge and Chrome on Windows 10. In the Opera test, Opera lasted 22 per cent longer than Edge. Google Chrome, a silent bystander in this clash, performed the poorest again.
