Think that until Mac officially announces MacIntel, no respectable site would release thorough tests and comparisions, only previews and hints of what might come... even if they have hacked versions of it running, they can't very well give you the results as they are hacked, i.e. illegal, versions of the software... so at most we can merely speculate on the possibilities...
for the interested though, can always tune in to various sites that provide info on "efforts in the direction of merging Mac software and Intel hardware"...
