Since most of the HTML5 components are come from previous versions (such as from basic HTML to HTML 4.01), HTML4-capable browsers still can support it. Since the HTML5 is released in 2012–2014, there were few browsers who claimed to have HTML5 support. According to Which Browsers Support HTML5? Chrome 10 had the highest score in The HTML5 test - How well does your browser support HTML5?, which is 301 out of 400 (now 300, since the maximum score increases to 555) should have more HTML5 compatibility. Firefox 4.0 has 249 out of 400 (now 215 out of 555). Opera 11.10 comes the next, with score 212 out of 555. Safari 5.1 scored 224 out of 555. The last browser to have good HTML5 support is Internet Explorer 10. It scores 265 out of 555. You can find the data in Which Browsers Support HTML5?, including for tablet and mobile OSes, as well as others such as game consoles, Kindle and smart TVs.
