The issue might be that the benchmarks shown during the presentation were for iOS, and the author here might have built for OS X. The other possibility may be that the we may need to tweak the compiler settings.
I certainly don't think that Apple was outright lying in their benchmarks. Those sort of shenanigans are a PR nightmare, and nobody thinks its worth it anymore.
I'm curious which period you're referring to here. I haven't been following Apple presentations in detail for a while, but I remember the iPad 2 announcement was chock-full of flat-out lies. Do you mean that this is something that's changed since then (March 2011)? Or do you mean that it's not worth it for developer-focused presentations vs consumers (who would presumably be more credulous)?
That article would be more credible if it didn't give two examples of dual-core tablets (Dell and Motorola) that shipped "in volume" that actually flopped. Which raises the question of just what kind of volume they were shipping in - probably orders of magnitude lower than the kind of volume the iPad 2 ships in.
Ah of course, that was dumb of me. I was remembering this from a few years ago but I should've taken the time to dig up a source referring to it. For some reason I was thinking "everybody must remember that".
Shock news: Marketing puts company's products in positive light!
All companies tweak the truth to make themselves look good (which company was touting their huge sales numbers when they had barely sold any products to actual customers, just retailers?). Apple aren't alone, they just get the most press.
I don't know why almost everyone in this thread is acting as if anything even incidentally negative about Apple is a personal attack on them and their family; it's really rather pathetic.
As you said, this is common practice, and Apple may or may not be one of the more egregious offenders [1], but it doesn't matter. I wasn't saying anything about Apple being shittier than other companies in this regard; I was responding to the parent commenter's claim that a company wouldn't do something like that these days. Now how the fuck is your claim of "Every company does this, leave Apple alone!" not in full support of my point (and arguing against a point that, as near as I can tell, nobody made)?
[1] IMO the lie about the Samsung quote is a level of dishonesty you don't see all that often but my point is that differences in degree like that aren't really relevant
