Chrome 37 has been promoted to the stable channel. This means that the 64-bit Chrome for Windows is ready for primetime. You won't be upgraded to the 64-bit version even if you use 64-bit Windows 7 or Windows 8, so you have to manually install the 64-bit Chrome 37 from this page. You can also click the "Windows 64-bit" from Chrome's download page.
"64-bit Chrome offers many 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% improvement in decoding performance. Stability measurements from people opted into our Canary, Dev and Beta 64-bit channels confirm that 64-bit rendering engines are almost twice as stable as 32-bit engines when handling typical web content," informs Google.
So why is 64-bit Chrome opt-in? It doesn't support 32-bit NPAPI plugins. This may be an important downside for some users, but Chrome will remove NPAPI support in the coming months anyway. Until then, the 32-bit Chrome will still be the default.
Chrome's "known issues" page informs that the 64-bit plugins for Java and Silverlight work properly, while the plugins for Google Earth and Google Voice don't work because they're 32-bit plugins. You can switch between the 32-bit and 64-bit Chrome versions from Chrome's download page.
