The beta version of Opera's latest browser, Opera 10.5, is currently the world's fastest browser, benchmark tests show.
According to tests run by Computerworld, Opera 10.5 was nearly 15 percent faster than Safari for Windows and almost 20 percent faster than Google Chrome, the previous number one and number two browsers.
Opera claims that Vega renders graphics about three times faster than the library utilised by Opera 10.10, the company's current production browser.
Other additions to the beta include a revamped interface that reduces the space allotted to menus, support for Windows 7 's Aero Peek and Jump List features, an address bar that brings the history and bookmark search of Firefox's Awesomebar to Opera, and the ability to mark any tab as private so there's no record kept of sites visited or actions taken within that tab.
Opera 10.5's beta is available for Windows only, but alpha builds of the Mac and Linux versions can be downloaded from the Opera Desktop Team blog.
The Norwegian browser maker has not set a ship date for the final of 10.5, but has said that the Windows version will beat the others to that milestone as well.
About the time that the final code for Windows is released, Opera will have the Mac and Linux betas ready.
Opera 10.5 beta can be downloaded from the company's website.
