I think the other issue is that a lot of these contracts were signed at the height of COVID, and with tsmc in high demand they have to pay what tsmc want, rarely do prices ever reduce once people are happy to pay a certain price the price is essentially set forever more, usually only up, rarely down. global foundries cannot compete with tsmc and Samsung are in bed doing mostly mobile chips.
To compare the price to a chip from 4 years ago, might be a little incongruous. AMD do need to make money on each chip they sell, and costs around them have increased dramatically, not just manufacturing but material costs also.
I don't think it's about being conditioned, look at Nvidia fan boys for that, virtually zero performance improvement but willing to pay way over the RRP just to get their mitts on them, but it's generally a fact of life, my shopping bill doesn't appear to be reducing am I being conditioned that the new pricing is the norm, I need to eat.soninhave to pay. I do however refuse to pay food prices at events, one place went to recently wanted £10 for a (yes just 1) cheese toasty, there were 3 of us, absolutely were not paying that.
