Chrome moves to 64 bit beta

Google has released a beta version of a 64-bit version of Chrome which looks stable enough to give its 32 bit version a good kicking.

Early users say that it is faster, stable and has better security capabilities than the current 32 bit version of Chrome.

The beta version of the 64-bit Chrome can be used on 64-bit systems and has nearly daily updates which can be irritating for those who do not like thinking about what their computer is doing.

According to Google, the 64-bit browser takes advantage of the latest processor and compiler optimisations, a more modern instruction set, and a calling convention that allows more function parameters to be passed quickly by registers. As a result, speed is improved, especially in graphics and multimedia content, where we see an average 25 per cent improvement in performance.

Google said that Chrome 64-bit could take advantage of the latest OS features such as High Entropy ASLR on Windows 8. Generally security was improved on 64-bit platforms anyway. Those extra bits also help us better defend against exploitation techniques such as JIT spraying, and improve the effectiveness of our existing security defence features like heap partitioning.

It has also noticed that there was an increase in stability for 64-bit Chrome over 32-bit Chrome. In particular, crash rates for the renderer process (i.e. web content process) are almost half that of 32-bit Chrome.
