No doubt about it AMD is sending conflicting messages about Vega.
The only things I have seen so far that I believe are...
Some one posts an order form online that was seen from a company who sells custom PCBS. Just two were ordered by AMD. This was oo, last September?
Raja posts on Twitter saying "In Taiwan talking about Vega !!" or something/somewhere like that. People reply to his tweet, he replies "Vega is a long way off".
We see a rig with what is apparently a Vega card in it. It has a really odd PCB with an extension on the back with a USB 3 connector in shrouded in duct tape.
AMD post the Vega logo at random intervals.
AMD announce the Frontier card.
Other than that lot? everything else you have probably read is bull toffee. Going on the past? AMD released Fury X (their last big card) in the summer, but it wasn't available until September and even then OCUK only had 9 of each make/variant in stock and they moved very, very slowly.
The only rumour lately that I might even possibly believe is that there are supply issues. This makes sense, because they had the same issues with Fury X. Mind you, even that might be BS.
I quote Kevin Bloody Wilson..
"Quite often I get to thinking, as I get around a bit, that half of what you read is bull and the other half's all s**t"
