The 12900K MSRP is $589, the AMD 5950X MSRP is $799.
Where is it $589? Its sold for $1,426.45 https://www.amazon.com/dp/B09FXDLX95 and the 5950X is $749 https://www.amazon.com/dp/B0815Y8J9N/ so the Intel is much more expensive in the real word than MSRP and the AMD is slightly cheaper.
Claiming that the Intel CPUs are "many times more expensive" than the AMD comparables is just wrong.
Edit: https://www.bestbuy.com/site/intel-core-i9-12900k-desktop-pr... Never mind found it for less here, wonder why it’s so much on amazon.
