I am saying I don't believe the HEDT rumors
I'm really not sure tbh man. I can't see why not though, if the rumours about the socket needing to be larger are true.
There were certain types of Opteron (the 16 core monsters) that were quite large. They were like a big old rectangle. Socket F? something like that.
What we do know is AMD have 32 core 64T chips either ready or possible. What I mean is, they've said that they are going to do a 32c 64t chip. If that's true (and I have absolutely no reason to doubt it) why would you limit yourself to just servers?
Intel do have some odd old Xeons out there, but these days unless they are massively threaded they usually release them on X99. And before that they released them on X79, meaning HEDT could theoretically use any one of them providing your board provider could be bothered to add support for them.
I personally don't think socket AM4 is going to be big enough to support anything more than it does now (IE 8c 16t).
As an example, 16 core Opteron.
And the board/socket.
Now obviously they have seriously shrunk things since then, but I just can't see them cramming the 32c CPU into a package as small as AM4. So that means they are going to need a bigger socket for those sorts of rigs, which means they would be daft to just make it a business thing and not market it toward people looking to build either a workstation, or a benchmark poser rig.
Intel must be selling the 6950x or they would not have bothered.
Right now AMD have Intel nailed to the post for desktop CPUs. Well, they will once they release Ryzen 5. The biggest question I have is what are they going to do about the 6950x and Intel's 100% dominance in the server/workstation market?
