Chrome 64-bit vs. Chrome 32-bit: performance, RAM consumption and security?

A while ago, we recommended you using Chrome 64-bit if you chose Google’s browser for Windows 64-bit systems. Initial testing for this version indicated that it was more stable, safer and faster in most usage cases than Chrome 32-bit.

A Digital Citizen‘s benchmark informs us of both versions’ current performance, their compatibility with the HTML5 web standard and another key element for a lot of users as well: RAM consumption.

The test was run on a mid-end PC sporting an AMD FX-8350 processor running at 4 GHz, an 8 GB of DDR3 memory at 2,133 MHz and a Radeon R9 270 graphics card with 2 GB of GDDR5 integrated memory in its core. Windows 10 Pro 64-bit with Creators Update was the OS used, and several benchmarks where run on it three times with the average score being recorded. The results were:

JetStream 1.1

This is a benchmark that runs latency tests measuring how quickly web applications can start and ramp up to a sustained peak performance, and run smoothly without interruptions. Higher scores mean better performance. Chrome 64-bit was an 8% faster.

Peacekeeper

It measures JavaScript’s performance and its ability to handle its most common functions, which are widely used on the web. Chrome 64-bit was a 4% faster.

Basemark Web 3.0

It measures the ability to render objects in 2D and 3D and crunch multiple CSS operations at the same time. It also indicates support for CSS3, HTML5, Flash and Silverlight and how fast the browser loads pages and send requests. Once again, Chrome 64-bit was a 6% faster.

Octane 2.0

It is a benchmark developed and maintained by Google. It measures the web browser’s JavaScript performance by running a series of tests that cover the most common usage cases found on the web. Chrome 64-bit was a 7% faster than the 32-bit version.

MotionMark

It is a benchmark that focuses on graphics performance. It is designed to stress the graphics system rather than the JavaScript’s engine. The difference is more noticeable here and, as before, Chrome 64-bit takes over at 16%.

Web compatibility

The HTML5 test indicates how well your browser supports the web standard and its related specifications. Google offers the same level of support, so both versions got the same score.

RAM consumption

RAM consumption is another important element to take into account, especially on low-end devices since Chrome is incredibly voracious in this sense.

For the test, a scenario as real as possible and identical for the two versions was used by opening several tabs running Gmail, Facebook, CNN, YouTube, BoredPanda and two for Digital Citizen themselves. The test tried to get the maximum possible content playing in each one of them by playing a video on YouTube and loading news on the social network tab.

The results turned out as expected. Chrome 64-bit eats up a lot more memory, taking 1.19 GB in this case, almost doubling the 32-bit version’s 634 MB, according to the OS’ task manager.

Conclusions

Chrome 64-bit topped Chrome 32-bit in every performance test. It ends up consuming much more memory, which is something to bear in mind if you run Chrome on low-end devices (4 GB or less), although it would not be a problem in current devices with 8-16 GB.

Stability is another element to take into consideration. According to Google, the 64-bit version is twice more stable than the 32-bit version, with the former showing half the errors of the latter in most web pages.

Lastly, let’s talk about security. Chrome 64-bit includes a 64-bit Flash plugin that is usually run on websites that require it typically to decrease the exploitation of all kinds of vulnerabilities, especially those related to loading objects from the memory, and other additional security features not present in the 32-bit version.

Google currently distributes the 64-bit version for Windows by default on Chrome’s download page. If you need the 32-bit version (only recommended for those cases involving low-end devices), you have to click on the option ‘download Chrome for another platform’.

Using 64-bit versions takes the lead, and not just on Chrome. Just today we witnessed Firefox 55’s being launched. Mozilla recommends using 64-bit versions if you work with devices running on Windows 64-bits since they say it is a lot less likely to run out of memory and freeze.

According to internal tests, Firefox’ 64-bit version reduces crashes by 39% on PCs with 4 GB of RAM. Mozilla intends to automatically migrate Widows 64-bit users to Firefox’ 64-bit version in its next launching.
