- Remove"discounts" applied against the purchase of intel hardware. The OEMs of the day couldn't easily afford this and would have gone out of business.
- Remove R&D support (and offer to further support the other OEMs...
Intel, by doing this stifled competition and removed options from consumers. AMD were denied access to some Tier 1 vendors e.g. Dell.
Would AMD have made a fortune given access to these markets? Who knows. Could AMD have fulfilled larger demands on its production? Who knows.
The EU, Japan, Korea and the State of New York (link

HP, Dell, Lenovo are 3 OEMs that today are using AMD Zen based processors in their products.
Which OEMs are avoiding AMD?
Market share. Bulldozer was not competitive with Core i7 or core i5. It takes time and sustained development to rebuild trust. AMD aren't doing badly with Zen. Navi, we will have to see.
AMD is serving an extremely useful service to CONSUMERS, it is providing a choice. If you want to see why that is important then look back a few years at intel pricing.
