I use an App called Quick System Info Pro (
http://slideme.org/application/quick-system-info-pro) and it tells me the EE's System Cache is 323 MB, Total memory is 502 MB (I think this is user memory), and it has a Marvell Mohawk rev 0 processor running at 788.07 MHz.
Quick System Info Pro tells me my PE's System Cache is 323 MB, Total Memory is 502 MB, and it has a Marvell Mohawk rev 0 processor running at 796.26 MHz.
Essentially the specs are the same with the PE processor running just a hair faster.
