Website AnandTech has run two speed tests on the internet browsers packaged with the next-gen consoles.
The first test, using Sunspider, a benchmark suite that aims to measure JavaScript performance, found the PlayStation 4 returned a result of 1,027.40 whilst the Xbox One managed 2,360.90. This being a speed test, the lower the score the better and this shows the PS4 browser runs over twice as fast as the Xbox One counterpart.
The second test used Kracken, a JavaScript performance benchmark created by Mozilla that measures the speed of several different test cases extracted from real-world applications and libraries. This gave the PS4 a score of 22,768.70 whilst the Xbox One was around five times slower with a rating of 111,892.50.
The downside to the improved speed is increased power consumption; AnandTech found the PS4 used more juice in every scenario apart from when in standby mode.
