Pong written in both flash and HTML5. Left side is flash, right side is HTML5.

Interesting problem of tuning both sides speed. Here (small Atom netbook hooked to big screen) the ball moves noticeably faster on the Flash side. To the point of making me lose a Pong match with myself.

Three generations old MBP with Chrome 7, everything is okay, both sides seem to be equally smooth.

my bad.. couple of reloads and it connected.

While I'm seeing better perf on the flash side (XP, FF 3.6.12), Pong isn't exactly an ideal test bed.

Interesting that on the page they say "We believe the two technologies are not in competition" but that is exactly what this type of demo is going to stir up. While the improvements in browsers and javascript engines as of late has been nice, I think we're still a few years off from real parity, especially on lower-spec'd machines. Make no mistake, Flash on the web will be obsoleted by HTML5. But not yet, especially for all those people who don't update their browser every month.

For the time being, if Flash evangelists really wanted to make a point, they should do this same type of set up, but with a complicated (hardware-accelerated?) visualization.

Why so somber? You also won the match! ;)
