Firefox 72 vs. Chrome 80 Browser Performance On Ubuntu Linux With AMD Ryzen
The JetStream performance is similar between the three browser configurations tested on this Ryzen desktop.
But when moving to the more modern JetStream 2 benchmark, Chrome 80 was faster by about 35%.
Chrome continues leading in the CanvasMark test, but at least WebRender provides some elevation to the Firefox competitiveness.
And with the MotionMark benchmark, WebRender really helps Firefox but they have a long way to go in competing with Google's Chrome build for Linux.
StylleBench is one of the tests where Firefox leads and with WebRender there is of minor benefit.
