Edge offloads the largest part of the workload to the GPU, but that comes at the prices of high GPU utilization. There is no clear winner, rather we can observe different strategies being used by the four browsers’ developers. The following table shows the combined CPU / GPU compute utilization of all four browsers. The following table shows the CPU and GPU compute utilization per browser while each browser was configured with the Intel GPU. The following table shows the CPU and GPU compute utilization per browser while each browser was configured with the Nvidia GPU.

The following screenshot from uberAgent’s dashboards shows average GPU compute utilization with Intel HD Graphics 4600:

All I had to do was have the four browsers concurrently run identical workloads and look at uberAgent’s dashboards afterwards. uberAgent determines GPU utilization per process, which is perfect for this kind of analysis. All other applications, including Desktop Window Manager and other OS components get the Intel GPU.īrowser versions used (latest at the time of writing):Īll measurements were taken with our user experience and application performance monitoring product uberAgent. Nvidias Optimus technology allows the user to control which applications have access to the Nvidia GPU.

All four browsers were running simultaneously on a Lenovo W540 equipped with Intel HD Graphics 4600 and Nvidia Quadro K1100M.
