Along with the release of 32-bit version of Chrome 37, Google also pushed the 64-bit version of Chrome to the stable channel today. 64-bit version was in the beta channel for the last month, and now it’s finally available in the stable channel.
64-bit version of Chrome 37 offers many benefits for speed, stability and security. For example it is 15 percent faster at decoding HD videos on YouTube, said Chrome team programmer Will Harris in a blog post. And don't forget that Chrome 64-bit can handle vastly larger amounts of memory and that offer more data-storage slots called registers that can improve performance.
