MacBookPro15,2 (ca late 2018) 13" 2.7GHz Quad i7, macOS 11.3, idle with no other applications running, compute times as recorded by benchmark. Likely this is the same system I used to report comment 2. Current Firefox Nightly with fresh profile and no other tabs, 33 runs: average 202ms, median 197ms, min 173, max 237, std dev 15.9 Current Chrome release, no other tabs, 33 runs: average 137ms, median 127ms, min 127, max 159, std dev 6.5 So, the firefox/chrome ratio is a little better than reported on the ryzen (202/137 vs 220/125) but there's a clear difference.
