Accessing the internet is one of the most basic tasks for any computer, but webpages in 2020 are incredibly complex so how the browser interprets the code and renders it as a viewable webpage is no simple task. Modern browsers have both a rendering or layout engine, as well as a scripting engine, and both factor into how well the browser can handle any particular task.

When the web first evolved, it was more or less a static affair, with webpages laid out in HyperText Markup Language, otherwise known as HTML, but as time passed websites became more and more complex, with it not uncommon today to run applications that would have been compiled programs several years ago. As such, browser performance is still an especially important metric for any PC user.

For 2020, the browser landscape has been shaken again, with Microsoft abandoning their closed source browser and moving over to the open source Chromium project, which as the name suggests, is the basis for the popular Google Chrome browser. After being in development for over a year, Microsoft has started updating Windows 10 PCs from Edge based on EdgeHTML to the Chromium Edge. As such, we figured it was a good chance to take stock of the browser landscape and see how some of the more popular browsers fare in terms of performance and battery life.

Although the web is based on HTML, with a standards body approving changes to the base HTML and therefore a level playing field, over the years it has never worked out quite as well as hoped, with web developers focusing on particular browsers that are popular or they are comfortable with, so over the years we have seen quite a few periods where specific browsers have been favored over others. Most readers will likely remember the days of Microsoft’s Internet Explorer 6 dominance, where websites would often only work in IE 6 thanks to heavy use of ActiveX. Internet Explorer has been a dominant feature of business and enterprise intranet sites, to the point where Microsoft is still forced to include and update their ancient browser even as they would like to move on. But that was certainly not the only time that has happened. Microsoft had the shoe on the other foot with the rise of mobile computing, where Webkit was the predominant browser thanks to Apple’s Safari browser on iOS, and Google using Webkit as the basis for Chrome as well.

What this means is that the web landscape, despite being open thanks to a standards body, has never felt as open as it could have been. One dominant platform or another has tended to be the one to drive developers to utilize new features that may not yet be ratified as web standards, or not yet supported by other browsers. So, although there is likely a group of people happy to see Microsoft abandon their own browser engine and move to Chromium, for the web it is not necessarily a net positive to see so much consolidation.

Today’s web landscape heavily favors browsers based on Chromium, which of course includes Google Chrome, but also the new Microsoft Edge, as well as Opera, Vivaldi, Brave, and quite a few more. Mozilla Firefox is the rare exception, with Mozilla developing their own browser engine in Gecko with Spidermonkey for scripting. Apple continues to offer Safari with Webkit, of which Chromium forked into Blink back in 2012.

Mozilla Firefox Gecko SpiderMonkey 79
Opera Blink V8 70
Internet Explorer Trident Chakra (JScript) 11

Although each browser has their own advantages in terms of features, design, and privacy, today we are going to just focus on how each browser performs. When an application is run on your desktop, most of the time it is going to be code that is written, then compiled. On the web, the code is not compiled, and instead the browser relies on its ECMAScripting engine to perform Just-In-Time (JIT) compilation. Because of this, browser performance is heavily impacted by how that scripting engine performs. We have seen advances in the scripting engine improve browser performance over time, as well as sometimes finding degradation as the engine is updated. And, of course, from time to time we have seen various vendors add specific code to deal with popular scripting benchmarks of the day.

The other side of the equation is battery life, meaning how efficient the browser and scripting engine is. The decline of the desktop has been happening for years with laptop sales continually outpacing desktops, so more battery life from your browser is likely a welcome addition.

For this test, we will be focusing on some of the more popular browsers available on the PC. As more of them consolidate around Chromium, we figured it was a good chance to look at how each browser performs, as well as look at the outgoing Microsoft Edge and even Internet Explorer to see if Microsoft has had to sacrifice performance during this transition.

    Just defected to Edge. Google's moat is breached. Reply

    Brave and Dissenter are Chromium forks which provide all of the Chrome browsing experience with none of the Google. That's a fantastic value proposition, especially when combined with DuckDuckGo for search. Reply

    I feel it's mostly about feature set at this point.

    I use FF on mobile because it supports extensions better, I use chrome on desktop because it supports extensions better.

    Edge's translation seems to suck compared to Chrome, and THEY SWITCH THE ORDER OF JAPANESE NAMES.

    No no no no no no no no no no no no no no no no no no.

    I have 600 Mbps internet connection and in Firefox it only goes to 400-420 Mbps on all online speed tests, while on Chrome it reaches full 600 Mbps. Maybe someone can explain to me why? Reply

    I used to use firefox but the UI changes were driving me nuts, switched to Opera years back. It has inbuilt mouse gestures, you can install any chrome extension (it's based on chrome), it has an inbuilt VPN, and it all just works. It may be owned by the chinese (not sure if that's the case) but who cares, they datamine constantly anyway, if you think they don't have your data, you are kidding yourself. Reply
