I'm really not sure what it is you are arguing against here.
Surely you recognize the commercial marketing aspects that belay the very purpose of organized "sponsorships", yes?
And who said Sysmark was a good tool to gauge anything? Maybe we are just talking past each other here, I wouldn't use Sysmark to assess anything that I was putting my own money towards.
And there is no doubt that AMD offers Ferrari something that is not reflected in Sysmark...namely world class support waiting hand and foot to make sure everything is running smoothly so as to risk nothing imperiling the goodwill that needs to exist between sponsors.
If AMD would come sit next to my computers and field on-site technicians in case something crashes during a press event then I'd say to heck with Sysmark benching too
But sadly not all of AMD's customers can expect the same sort of AMD experience,
and so some of them will be compelled to let Sysmark do the talking. (not that I would, but clearly some people are and will be)
