The latest Macworld magazine has a review of the Intel iMac.  The speed 
hit for running non-universal applications, using Rosetta software 
translation, depends on what older machine is being compared, what 
older machine you are leaving behind.

Three functions tested in MP3 Encode, Photoshop Suite, and MS Word 
Scroll ran in roughly one half to one third the time on the iMac 
G5/2.1GHz and in about two thirds to three quarters the time in the 
eMac G4/1.42GHz.  But the iMac Dual Core machines ran the tests in two 
thirds to three quarters the time required in the iMac G4/700MHz, the 
slowest model with the half-basketball base.

So I'm guessing that the iMac Dual Core using Rosetta for old OS X 
applications is roughly equivalent to the performance of the single CPU 
Quicksilver 2002 models at 800 and 933MHz.
