According to a Microsoft blog post, Edge was 112% faster, 11% faster and 37% faster than Chrome in three different speed tests. Chrome surpassed Internet Explorer as the most popular browser in the U.S. last year in large part thanks to its speediness.
Consumers will get a chance to try Edge for themselves when it launches as the default browser with Windows 10 on July 29. One of the browser’s main selling points is its deep integration with Cortana, Microsoft’s Siri-like virtual assistant, as well as the ability to mark up web pages with sharable annotations.
Microsoft isn't yet killing off Internet Explorer completely, both it and Edge will co-exist in Windows 10 for now.
