Following successful runs in Google's Dev, Beta, and Canary channels, the 64-bit version of Google's Chrome browser for Windows is now available as a stable release (Chrome 37). That means you can have all the benefits of the 64-bit version without the risks of instability that come from running pre-release software. According to Google, 64-bit Chrome offers a bunch of benefits for speed, stability, and security.
"Our measurements have shown that the native 64-bit version of Chrome has improved speed on many of our graphics and media benchmarks. For example, the VP9 codec that’s used in High Definition YouTube videos shows a 15 percent improvement in decoding performance," Google stated in a blog post.
According to Google, the 64-bit rendering engines are nearly twice as stable as the 32-bit engines when handling typical web content. On top of that, security safeguards such as Partition Alloc are able to "far more effectively defend against vulnerabilities that rely on controlling the memory layout of objects." In other words, 64-bit Chrome is pretty much better than the 32-bit variant in every single way.
Be that as it may, the 64-bit version will remain opt-in, Google said. You can download 64-bit Chrome here.
