Last month, Google released 64-bit version of Chrome for Windows for the first time. The two brand new 64-bit Dev and Canary channels for Windows 7 and 8 users, giving a faster and more secure browsing experience. It includes several improvements in speed, security and stability: Speed: 64-bit allows us to take advantage of the latest processor and compiler optimizations, 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% improvement in performance. Security: With Chrome able to take advantage of the latest OS features such as High Entropy ASLR on Windows 8, security is improved on 64-bit platforms as well. Those extra bits also help us better defend against exploitation techniques such as JIT spraying, and improve the effectiveness of our existing security defense ...

The news courtesy of Ian Forsyth, program manager at ARM.  He did not however say when this 64 bit OS will show up on ARM’s chips. ARM has just announced its first 64-bit processor designs, Cortex-A57 and Cortex-A53, which are based on ARM’s Armv8 architecture. ARM said that it expects servers and mobile devices based on the processors to reach the market in 2014. Nvidia is developing a processor core based on ARM’s 64-bit architecture under the code-name Project Denver. A Qualcomm spokeswoman said the company cannot comment at this time on specific product plans. Windows RT, which runs on ARM, is currently limited to 32 bits, unlike the desktop x86 Windows 8, which has no problem with both 32 and 64 bit chipsets. While it will be some time before these ...
