>That should be next to nothing for a premium laptop.
For low end to mid range laptop a BOM cost of $9 is a lot. Especially to PC manufacturers, so bad that installing crapware becomes their major source of revenue. For high end the marketing budget comes in form of Rebate.
One of the major reason AMD got off to a good start from major manufactures is actually because Intel cant even provide them enough chip in the first place. And hence intel hasn't done much to push back at all because they dont have the capacity right now.
Which is why I said "premium laptop". I don't expect lower end laptops to include it regardless of the cost of the controller itself. There's far more than the $9 involved: greater PCB complexity, additional ICs, extra connectors, etc.
But a premium line like HP's Z-series includes TB even in the lowest config (i5-8400, UHD 630 iGPU) starting at ~$3500. I'm reasonably certain that going with AMD CPUs would actually lower the BOM despite the extra $9 TB controller. Intel CPUs are not cheap.
