For Vega they needed HBM otherwise that card would have used over 500 Watt with GDDR5 and still not be able to run high clocks.
Checkout Buildzoid he tested Vega and explained why it would not have worked with GDDR5.
Since when do you get large discounts when there is scarcity?
Do you understand how signed contracts work? You pay a set price no matter what. Sometimes there is even payment penalties if the manufacturer cant deliver enough parts as well. AMD may have paid more until Hynix could deliver the quantity needed. However many have clauses on non delivery by a certain date which means Hynix had to pay the difference. We will never know cause we will never see the contract signed for HBM and AMD helped develop it as well which likely set prices far different then what they would charge somebody else. Biggest problem with HBM is the complexity it added to the package which AMD even struggled with at first. It's more expensive then GDDR but not by as much as most think and they kept GDDR on the lower end stuff that sells in large quantities, like they should.
