To quote: Here's the site description of the speed tests:
• Richards: OS kernel simulation benchmark, originally written in BCPL by Martin Richards (539 lines).
• DeltaBlue: One-way constraint solver, originally written in Smalltalk by John Maloney and Mario Wolczko (880 lines).
• Crypto: Encryption and decryption benchmark based on code by Tom Wu (1,689 lines).
• RayTrace: Ray tracer benchmark based on code by Adam Burmister (3,418 lines).
A few notes: First, your mileage may vary; I ran these tests on my dual-core Windows XP machine.
Second, my apologies here to Opera, whose browser I don't have installed.
Third, I tried to run the SunSpider benchmark tests as well, but perhaps because a lot of other curious people had the same idea on the day Chrome launched, I couldn't get to...
