Browser Benchmark: New Chromium-based Edge vs. Edge, Chrome & Firefox

In December 2018 Microsoft announced, to the surprise of many, that they would be replacing their existing Edge browser with a new version based on the Chromium open-source browser project. Other browsers based on Chromium include Google’s Chrome, Opera, and Brave. Microsoft also announced that they would be actively contributing to the Chromium project, which appears to be the case, with over 275 commits as of April 8, 2019.

The replacement for the original Edge browser, hereafter referred to as Chromium-Edge, is still in early development, with no beta release available as of late-April 2019. However, being based on a mature engine like Chromium, it is still and loads most sites without issue already. What is currently offered via the Microsoft Edge Insider site, are versions for Windows 10 in a Dev build channel with targeted weekly updates, and a Canary channel offering daily builds. There is a Beta channel listed, suggesting updates every six weeks, but so far no beta is available. The Insider site also lists Windows 7, 8, 8.1 and macOS as platform targets coming soon. That last bit is interesting since Microsoft hasn’t developed a broswer for Mac since Internet Explorer 5 Mac Edition’s last update in 2003.

Given that this is a significant shift in browser strategy for Microsoft, I decided to test what the performance impact might be for Windows 10 users. Using a variety of benchmarks, I tested the new Chromium-based Edge browser against the current releases of Google Chrome (73.0), Mozilla Firefox (66.0), and the EdgeHTML-based version of Microsoft Edge (44.17763) in Windows 10 1809. Microsoft has only released early builds of Edge in its Chromium flavor, so I tested the initial Dev release (74.1) and one of the daily Canary builds (75.0.134). The benchmarks used for this test are:

  • Google Octane 2.0
  • Sunspider 1.02
  • Mozilla Kraken 1.1
  • Speedometer 2.0
  • JetStream 2
