"If Ryzen is more than that, I don't see it taking a big bite out of the market. Which isn't surprising, as Intel did just halve the margins on their enthusiast parts..."
Either it is more than that, and it will take huge chunk of the market, or Intel simply reduced margins out of the goodness of their heart.
I don't understand what you're trying to say. My point was that a $1k Threadripper would have absolutely destroyed Intel's 2016 lineup, but it'll merely be competitive with what was announced today.
If the top end SKU is more than $1k then I don't see it taking much of the market, due to the factors in my original post, factoring in the total cost of a machine and inertia greatly favoring Intel.
I was trying to say that AMD did threaten Intel with market share, and they countered that with lowering prices.
As for the rest of your post, it depends. HEDT is diverse. I was looking for a new CPU for my hobby project, 8 - 16 cores, still undecided. I have literally 0 FPU needs, but will take any integer power there is.
I also pay for electricity, so, 65W AMD vs 140W (at least for 6 core) Intel makes my decision very easy.
You also have to consider that AMD HEDT is announced and arriving. Intel response is all marketing slides right now, full with TBDs. They are also misleading people that the chunk of cache they moved from L3 to L2 will magically be all IPC gains.
I own right now more Intel than amd machines, but moving forward my TOC says AMD is the clear winner.
I do hope Intel will come back, but realistically, they are still overclocking sandy bridge. It may take them several years for a new architecture.
Either it is more than that, and it will take huge chunk of the market, or Intel simply reduced margins out of the goodness of their heart.
