Google Chrome for Windows now has a 64-bit version

Today Google has announced a 64-bit version of Chrome for Windows with the introduction of 64-bit Dev and Canary channels for Windows 7 and Windows 8 users. You can download both of them from here: Dev and Canary. The 64-bit version is offered by default if you are running a 64-bit version of Windows, but a 32-bit version will still be available. There are three main advantages of the 64-bit version of the browser as reported by TheNextWeb:

Speed: 64-bit allows Google to take advantage of the latest processor and compiler optimizations, a more modern instruction set, and a calling convention that allows more function parameters to be passed quickly by registers. As a result, speed is improved, especially in graphics and multimedia content, which sees an average 25 percent bump in performance.
– Security: 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. Those extra bits also help better defend against exploitation techniques such as JIT spraying, and improve the effectiveness of existing security defense features like heap partitioning.
– Stability: Google has observed a marked increase in stability for 64-bit Chrome over 32-bit Chrome. In particular, crash rates for the renderer process (i.e. Web content process) are almost half.

If you install the 64-bit version, it will replace the 32-bit one. It will import all of your settings and bookmarks in the new install.
