Alright, if no-one else is going to volunteer themselves, I might as well do so myself. I don't have the expertise of someone like AlStrong, but I've been studying the chip pretty extensively over the past year and a half, and have spent enough time poring over die photos of R700 chips and so forth that I would feel fairly comfortable figuring out the vital statistics, at the very least. I can also have a decent stab at the rest of it, so things like the memory interfaces, internal changes to the GPU cores, the type of ARM core and DSP used, etc., but of course couldn't guarantee that I'll get all of that stuff 100% accurate (it's only for the real nerds, though). What I might do is PM Blu and Durante, and if neither are willing to do it themselves, I'll ask them for pointers on specific components, and go to them with any questions I have while doing it. Best to have back-up for something like this, I suppose.
I also think (hope) that I've been here long enough to be trusted with it, although of course if people don't feel so I wouldn't be offended. I have the next couple of days off, as well, so I have enough time to really put the work in on it. I should say in advance that it may be a few days before I could post anything, both because I'd want to have a lot of time to simply go over the photo, and also to make sure what I'm writing is accurate and run it past people like Blu, Durante and AlStrong for errors. As soon as something like this gets posted on GAF it's going to be all over the internet within 10 minutes, so there isn't really much scope for screwing up.
Anyway, we can give folk a little more time to mull it over, then take a decision later tonight.
