You can look up the processor revision/stepping here:


You can search by model number, etc. on the left side or more 
specifically by the cpu OPN (e.g., ADO4600CUBOX) on the right 

If you select steppings G1/G2 and then pull down the model list, 
you can see the range of processors in each stepping.  I don't 
think any of them are quad/triple cores.

Searching the "3800+" and knowing it is 65 watts (EE) shows 
either an F2 or F3.  Likewise, the "4850e" is a G2.

Checking the cpuinfo on systems using a 4850e (G2) and a 4600+ EE 
(F2) both give "cpu family: 15", so they have included the Gs in 
the excluded group, too.
