HTML5Test is exactly what its name says. We saw no version number, though a perfect score is 555.

For this benchmark, a higher number is better.

Chrome loves HTML5:

html5test_chrome_september_2015

Firefox does as well:

html5test_firefox_september_2015

Edge has a ways to go:

html5test_edge_september_2015

Nobody got a perfect score, though Chrome came the closest.

Browser standards are a moving target, though this benchmark does show that Google is pushing the envelope.
