intent exactly
and as far as I can tell it's quite unlikely that there is bad intent involved
as far as I understand DIY sells of Threadriper solely exist for PR, mind share reasons a bit of edge case handling and maybe some book keeping trick to even out certain marked OEM demand fluctuations.
but I don't think they make relevant amounts of profit with DIY sells
I mean think about it most (by far) end users of Threadrippers are companies needing it for work stations.
Most larger companies only buy from OEMs like DELL for various reasons like warranty handling, uniform platforms, certain "enterprise" BIOS features etc.
Even for small companies the DIY part is often an issue, they might not have IT experts and even if this system goes e.g. to a software developer they might not be willing to hardware maintain their PC (and take responsibility for it).
This leafs a relative small number of private enthusiasts and small companies, to small to really be profitable.
Add to that that the demand of DIY is less predictable then that of OEMs, and production capacities for CPUs tend to be limited and even if less so currently tend to still often doesn't allow fast dynamic changes of the amount.
Idk. but if I would be AMD I think I would pin down my big customers on contracts with a more fixed demand (both fixed initially and fixed+%variety follow up) and then plan CPU production of that (with maxed out variety) and if there are any spare factory resources I would use them for either server CPUs or desktop CPUs whatever currently sells hotter. Then if the OMS don't max out their variety I would stock the remainder and once enough stock accumulated pass it the the consumer facing department to sell as DIY parts.
