Windows 10 came with a lot of new features and one of the most important additions is the new Microsoft Edge browser with Cortana integration. This browser, which was codenamed Project Spartan, replaces the old and criticized Internet Explorer, which was becoming less and less used.

So, is Edge good enough to make the users forget about the Chrome or Firefox browsers? Below, you’ll find a comparison between Edge and Internet Explorer 11 and you’ll draw conclusions based on the new features and performance.

User Interface

Microsoft hasn’t worked much on the UI of the new browser, because the logo seems similar and only a few changes were made to the page layouts. But the Edge is definitely more impressive than the previous browser, as it has a more minimalistic interface, which offers a sleeker experience (IE had a clunky navigation). It’s not as gorgeous as Chrome, but it’s very aesthetical. And the navigation buttons have been reduced as much as possible.


New Features

The previous IE didn’t have the best functionality, as it lacked many features, but Microsoft tried to fix this problem and came with some features that will please a lot of users. The annotation feature involves a button located at the top, which will overlay OneNote onto the web page you’re visiting, and will allow you to write notes, draw or highlight sections and even copy some parts of the page and save them to OneNote or share them via different channels.

Also, the Pocket-style Reading List function saves any webpage to a list and you can read it later. Consider it a temporary bookmarks feature.


Without a doubt, Microsoft did its best to make Edge more responsive and slicker than IE, which has an inferior performance. It has no problem dealing with HTML5 content, and in the HTML5 benchmark tests, Edge managed to score 402 out of 555, while the predecessor obtained a score of 348.

In the Jetstream Javascript benchmark, the old browser had scores of 33.7 and 34.2 respectively (the average score was 33.9), being way behind Edge, with an average score of 51.4, obtained from 45.7 and 56.4.


In the Sunspider Javascript benchmark, however, it seems that Edge was outperformed by IE, but you shouldn’t take this test into consideration, because the developers are no longer maintaining it and the results aren’t really reliable.

The users will notice that Edge requires more memory that IE, and to give you an example on what to expect, then open 14 tabs, play a video and run a web-based photo editor, and you’ll see that Edge will use 27.2MB of RAM, while IE will need only 12.9MB of RAM.

Even the boot time is faster with Edge, as it requires 17 seconds to load 14 tabs, with four seconds more than IE.
