Following comparison is made using automated tools on a machine with following specs:
  • OS: Windows Vista (32-bit)
  • CPU: Intel Core Duo (2.16 GHz)
  • RAM: 3 GB
  • Computer: Dell XPS M1530

Clearly Chrome is the winner in overall performance

Conclusion with Standard Deviation

Based on used performance metrics it’s evident that Chrome is overall best browser in terms of performance.

Now if we calculate its variance and standard deviation to determine how better chrome is compared to other browsers.

I will only use CPU usage as performance metric for these calculations

Mean = (11.3+    18.1+    3+    7.6+    4.4 ) /5 = 8.88
Variance =  (5.85 + 9.22 + 34.57 + 1.638  + 20.07)/ 5 = 14.26
Standard Deviation = 3.78
