In the case I am looking at (~960x 12 cores for a renderfarm), these cores will be maxed out 24/7. In 3D animation, raw horsepower is still king, and people will always want more power to keep up with demands for yet higher levels of "Wow!" that are being placed on even small production houses that simply cannot purchase this kind of firepower. Outsourcing is increasingly popular.
For the people comparing these to various desktop parts, That is the target audience that AMD is looking at. Although a few guys here will no doubt pick these up (XS Crunchers mainly, I would love too assuming I had the disposable to do so), do you really think that the whole of XS's purchases of these processors will equal even that single sale? And this is XS, the leading edge of the Enthusiast market.
These chips are not comparable to the desktop parts, and were never designed to be.
