This means that Windows users who have opted to get the 64-bit versions of the OS can now run a version of Chrome that is fully optimized for their system. The 64-bit version is shown as an optional download on the main Chrome website. A 64-bit version for Mac OS owners is still in beta testing.
In a blog post, Google had this to say about the launch of Chrome for Windows 64-bit:
"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. Finally, on 64-bit, our defense in depth security mitigations such as Partition Alloc are able to far more effectively defend against vulnerabilities that rely on controlling the memory layout of objects."Also, Google Chrome 37 is out now with improved font rendering and various bug fixes.
