I would imagine that the typical reviewer's guide does this as well. Maybe just taking it to the next level? I can understand a company not trusting the Press to not do a hack job. Maybe with Kepler it's a bit more complicated. With the rumors of wildly varying performance, and all.
Yep, and Charlie stated that GK104 would have wildly varying performance depending on application so maybe Nvidia is trying to create an extremely controlled testing environment? I'm just speculating here, but based on NV's shenanigans in the past I wouldn't put it past them. If history has shown anything, their marketing methods and such are shady to say the least. This is why i've always found nvidia distasteful despite them making good hardware.. that and their fanbase is so full of hotair...anyway..I'll still buy their stuff (if its good) but its like me buying an apple product. I cannot stand the people behind the company and usually root against them. I probably wouldn't shed a tear if a nuke was dropped on Apple HQ, I kid of course.
I especially loved how nvidia hyped the GTX 480 to death and bragged of it being 5 times faster than the 5870. We all know what happened there, and if I were a betting man I bet the same thing will happen this time. Same or slightly faster speed despite all of the hype , fake slides and rumors. But how many people honestly think that Kepler == 3 GTX 580s? Nvidia hype marketing machine at work, gotta love it.
