Um, IDC got run off by people jumping down his throat over all kinds of things: Intel's 14nm yield problem, something to do with Apple's A9, and some other crap. I don't remember the AMD fans being much of a thorn in his side, at least not right before he left.
I'll reiterate, if you don't like certain posters showing up in every thread that even looks slightly pro-AMD and poo-pooing the whole thing, just put em on ignore.
Considering that AMD's last relevant CPU was 9 years ago (pre-Conroe), that isn't too surprising.
Actually, I'm surprised that the Zone has gone downhill. There's an active AMD subforum on OCN, and we have AMD chatter here, albeit much less. You can still own the hardware and talk with other AMD fans about how to best make use of it regardless of how "relevant" is said hardware.
The Zone could have been all about promoting HSA by using the limited toolset (there were at least a few folks there with the talent to do it) or any number of things, but instead it just ran dry.
Which is odd, considering how often AMD continues to trot out "Zen is on track for sure!" news releases. For our purposes, they may as well just be puff pieces, but at least AMD's marketing department - such as it is - seems to understand that more than a few people are skeptical of AMD's ability to deliver on future products.
