Benchmarking browsers is a somewhat silly exercise, since scores cannot be replicated on a variety of hardware, and it is not uncommon for even the same system to fail to replicate benchmarks scores, especially in JavaScript tests in two succeeding runs. The guys over at ConceivablyTech have an interesting approach, running browsers through multiple tests on different sets of hardware (including an Android smartphone), and showing the scaling differences between browsers when you are using a dual-core netbook on the low-end and a six-core desktop on the high-end. They also tested HTML5 on Firefox mobile and found the browser has better HTML5 support than the current Firefox 4 Beta 6.
