64-Bit Chrome For Windows In Beta Phase

64-Bit Chrome
After a short test phase, the 64-bit version of Chrome for Windows is now available in a beta. A fianl version will be released later this year. Even though the hardware and operating systems are fit for 64 bit, many software manufacturers do with the switch to the new architecture more difficult. In the browser world, only the Internet Explorer (since version 8) is available as a 64-bit version.

Now Google Chrome is following the suit and is releasing the 64-bit beta version of their fast browser in beta mode which is meant for the Windows users. A 64-bit version of the Chrome browser is available now to users of Windows 7 and 8 and is in beta development mode. This move shows that Google considers this version is stable enough for a wider public, which would most likely to appear as a final version with Chrome 37 in late August or even within six weeks.

What is surprising is that, as compared to Mozilla, very short test phase of the 64-bit version in the so-called Dev and Canary development branches, which had begun in June. For the Firefox; the developers are experimenting with a 64-bit version for Windows Years together, but they have never released a stable one. According to the internal testing the 64-bit version of Chrome, however, is now much more stable than the 32-bit version, which has been confirmed in the two-month test phase as well.

Above all, the crash rate of the rendering process had significantly reduced. Although the main advantage of 64-bit programs rarely comes (more than 3.2 gigabytes of addressable memory) for smaller programs such as browsers to support, but the development should be also applied here in the future. A real advantage is improving the security of Windows-8-users who do not currently have.

 In Windows 8 Chrome can use with high entropy due to the 64-bit Address Space Layout Randomization (ASLR), which also help to better fend off JIT-Spraying attack. In addition, existing defense mechanisms, such as the heap partitioning is more effective.

According to Google, the larger word width also allows "the use of processor and compiler optimizations, modern instruction sets and calling conventions, which allow more function parameters are quickly passed by the register."

This should be accelerated in particular with the presentation of graphics and multimedia content. Google tells that the average performance increased by 25 percent. In their first announcement of Google promised its users more speed, security and stability.

 The 64-bit beta of Chrome 37 is available for Windows now for download and can be used as a complete replacement for the previously used 32-bit versions.
