The debate between HTML 5 and Flash has been going on for some time now, but it was Steve Jobs favoring one over the other that sparked up the rivalry once again. We know that both the new Apple iPhone and the iPad will not support the Flash Player and for good reason — it is a CPU hog.
Streaming Learning Center has been doing some tests of their own; they played a video from YouTube twice — once in HTML 5 and the other in Flash to measure CPU usage. HTML 5 did show that it was faster, but it was not a clear winner like Jobs suggests.
Engadget explains that the test did show that HTML played better in Safari on a Mac, but running on Google Chrome and Windows and Firefox — Flash Player 10.1 was actually faster. The reason behind this is how Flash is able to take advantage of the CPU hardware acceleration in Windows; this is something that Apple hardware does not allow.
What do you prefer HTML 5 or Flash Player?
