Think you got the wrong idea. I'm not referring to special sauce. I'm saying how do we know that what is now known as GCN not somehow representative of most, if not all, of the same "customizations" that Microsoft are referring to? I'm saying maybe they had a lot more influence on standard GCN than originally suspected. We were introduced to GCN well before either console ever launched, so maybe due to that fact we're viewing it from a perspective of well, It's just GCN, this released back in 2011, so they couldn't have customized much, if anything at all.
When Microsoft talks about heavily customizing the command processor, maybe that same heavily customized command processor is what's inside of all GCN GPUs, meaning the PS4 also? Get where I'm coming from now? And before I get an even more immature response, no, I'm not somehow trying to give Microsoft credit for building the GCN architecture. This, after all, is what AMD does.
