A week in advance? And, none of the companies you listed sell components. What does Google sell that anyone needs benchmarks for? Microsoft and Apple both sell products whose performance is derived from a number of different components, all produced by someone else. Both AMD and NVidia used to paper launch quite frequently, but I can't ever remember NVidia publically announcing a reveal date for a new architecture just to announce they didn't actually have anything ready for release. And even more embarrassing, AMD didn't even have press samples available for reviews. How much of an improvement is AMD going to be able to muster from the drivers in a week? Why don't major review sites have reviews up yet of a card supposedly ready for public release in a week? In recent years NVidia has been quite good at having cards ready the day they are officially announced, with reviews.
Straight trolling? That's a bold move Cotton. All of those companies have branded hardware and software products. iPhone, iPad, Mac, OSX, Google's Nexus phones and tablets, new Android versions, MS Surface, Windows Phone, XB1, new Windows versions, etc. Do you actually think Apple, MS, and Google have little understanding of the products they design? Who produces or assembles the final product is immaterial. That's the way the world works.
Why would AMD have press samples at a product launch? My point that you missed is that AMD's formatting is entirely inline with normal corporate practices. The GPU review industry has been a deviation from that format. Arguing that AMD must conform to whatever format Nvidia chooses is just silly.
