Google's 64-bit Windows version of Chrome is currently available for preview, promising that the browser is more stable and faster than its 32-bit sibling. The new 64-bit Chrome was advanced to the "Canary" and "Dev" channels.

Available for Windows 7 and 8 users, the 64-bit Chrome allows users to take advantage of the latest processor and compiler optimizations, supports a more modern instruction set, and a calling convention that allows more function parameters to be passed quickly by registers. The result is a faster performance in graphics and multimedia content, where Google sees an average 25% improvement.

With Chrome able to take advantage of the latest OS features such as High Entropy ASLR on Windows 8, security is improved on 64-bit platforms as well.

Finally, Google says that the 64-bit Chrome is more stable than the 32-bit version, with crash rates for the the renderer process (i.e. web content process) to be almost the half.

Apple's Safari has been 64-bit on OS X since 2009's version 4. Microsoft's Internet Explorer has been available in 64-bit since 2006's IE7, while Opera Software also offers a 64-bit edition on Windows.

Google currently offers a 64-bit browser for Linux, and is working on one for OS X.

Mozilla has long had 64-bit versions of Firefox for OS X and Linux, but has yet to push a 64-bit Windows edition into its prime release channels.
