As noted previously, the 64-bit version of Google’s popular browser should be faster than its 32-bit counterpart, especially in graphics and multimedia content, and also safer because of its ability to leverage new OS features such as High Entropy ASLR on Windows 8. In addition, 64-bit Chrome should feel more stable than the 32-bit version, with fewer crashes during general use.
The new 64-bit version of Chrome is still a beta, so a few bugs should be expected. The relatively short amount of time from the Canary and Dev channels suggest a stable release might not be too far away. Fingers crossed.
