Well, sorry I don't have a whole lot of (recent) computers to compare, but here is one speed comparison... I ripped a DVD (48 minute, unprotected) using HandBrake to H.264, 2-pass encoding, de-interlaced. (All other options default, including the wonky 704x400 resolution it picked.) It took 55 minutes running HandBrake natively on my 2.0 GHz Core Duo with 2 GB RAM. (average 21.3 fps.) Which means that the 2.16 GHz Core Duo MAY be able to handle it in real time (24 fps,) and the upcoming batch of new processors from Intel (Merom/Conroe) will certainly be able to do it. When run in Rosetta... Well... I gave up because the estimate had it taking over 4 hours. But after 45 minutes, it had averaged only 4.5 fps. (Which is on pace for 4 hours, 15 minutes.) On my 1.25 GHz G4 eMac with 768 MB RAM, it took 4 hours, 25 minutes, averaging 4.4 fps. Yes, that means a 2.0 GHz Core Duo running through Rosetta is faster than my 1.25 GHz G4 running natively at H.264 encoding.
