Google yesterday announced 64 bit support to chrome with two brand new 64 bit dev and canary channels for windows 7 and 8 users, giving us more secure browsing and experience. If you want to download the 64 bit installer from the Canary and Dev download pages.
The new version will just replace your current chrome installation without affecting your settings and bookmarks so there is no need to uninstall your current chrome version. The new 64 bit of chrome includes several improvements which are listed below:
- Speed: 64-bit allows us 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, where we see an average 25% improvement 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 us better defend against exploitation techniques such as JIT spraying, and improve the effectiveness of our existing security defense features like heap partitioning.
- Stability: Finally, we’ve observed a marked increase in stability for 64-bit Chrome over 32-bit Chrome. In particular, crash rates for the the renderer process (i.e. web content process) are almost half that of 32-bit Chrome.
