> But marketing isn't really known for being technically accurate, why would Apple's be any exception? The comments and emphasis about the benefits on unified memory come right out of Johny Srouji's mouth. Granted, everything Apple execs say is vetted by marketing and legal, but I can't see Srouji emphasizing a made-up marketing point as a weird red herring either. As I mentioned above, someone on HN has "debunked" every single optimization Apple says they've done. But the numbers don't lie. Somewhere along the way, some of the "debunking" is full of shit. I'm guessing most of it is. The simplest explanation is that Apple is being forthright here and people don't understand what they've done or how those optimizations work.
