If I am to buy an ARM server, I can ask prices to AMD and, let's say, generic manufacturer XYZ that also sells vanilla A5x based SoCs. If my design isn't too complex to the point of Freedom Fabric not being the deciding factor but a nice plus, as there isn't any differentiation between the two chips, I can just make the two race to the bottom.
AMD may win the order but at razor-thin margins. This model could work for Seamicro alone, but it does not work for a company that designs its own chips.
This is AMD's challenge. They are approaching the traditional ARM customer (who is use to commodity-like pricing for a commodity-like product) and asking them to be willing pay a price premium for the AMD solution on the basis of the solution containing a proprietary network fabric.
That is a tough sell!
My prediction is that freedom fabric is going to end up being the new iGPU - you give it away for free as an incentive to the customer to buy the otherwise non-noteworthy CPU.
It will be a tough future for AMD, no doubt. If they make any kind of headway in terms of creating a market for 64bit server ARM then any number of much more enriched ARM players will decide they should pursue it too.
Not too mention Oracle, IBM, and Intel who will create their own ARM server competitors if they see ARM servers taking much in the way of marketshare from their own bigger iron products.
