Performance comparisons using two popular benchmarks, Speedometer, Octane v2, Octane v1, and Jetstream2. The leftside images are Chromium, and the rightside images are Thorium. Testing was done on my main machine: AMD FX-8370 overclocked to 4.5 Ghz. | 24 GB 1600 Mhz. DDR3 RAM | Nvidia GTX 970 | Gigabyte GA-78LMT-USB3 R2 Motherboard. The browsers were run on a fresh, updated install of Ubuntu 22.04.1 codename "Jammy Jellyfish", with no other major background tasks runnning.
Speedometer v.2.1: Chromium vs. Thorium | 71.9 vs. 106 | – 38.3361% performance gain.
Octane v.2.0: Chromium vs. Thorium | 28394 vs. 31108 | – 9.12238% performance gain.
JetStream2: Chromium vs. Thorium | 95.869 vs. 104.823 | – 8.92313% performance gain.
Octane v.1.0: Chromium vs. Thorium | 26492 vs. 27959 | – 5.38833% performance gain.
I also tested some other popular Chromium based browsers: Google Chrome, Brave, and Vivaldi. (Click on their scores to see screenshots.)
