Berdych broke Federer four times, with the final break coming in the seventh game of the fourth set. Berdych served 12 aces, was broken just once and saved seven of eight break points.
Federer came in with an 8-2 career record against Berdych, having lost the first match at the 2004 Athens Olympics and the last in Miami this year.
"I don't think I played poorly," Federer said. "I think he went after it. I know Berdych. I think I've played him 10 times already before. That's the way he plays.
"I think he's been able to play more consistent last year or so, and I was just not able to defend well enough and I didn't come up with the good stuff when I had to. It was disappointing."
Lu stunned three-time finalist Andy Roddick in the fourth round, but couldn't replicate that performance against Djokovic, the 2008 Australian Open champion.
Djokovic lost just 12 points in 13 service games. He won 26 of his first 28 service points, including 15 in a row. The Serb had 29 winners and 17 unforced errors, and converted five of 15 break points.
"Nothing is easy these days, especially at this stage of the tournament," Djokovic said. "But the way I played, I deserved to win. I was hitting all the shots and I was really playing very solid from all parts of the court. I'm very, very happy with the performance today."
Djokovic reached the semifinals here in 2007 but had to retire against Nadal with a foot injury while trailing in the third set.
"This time physically I'm fitter," Djokovic said. "Those were very strange conditions and circumstances. I had to play three very long matches in three days and couldn't hold on in the semifinal. This time everything is in order and I'll give my best."
