The 28C/56T Platinum 8176 sells for no less than $8719
Actually, the
big customers don't pay that much, but still... For that, it had
better be made of platinum!
That's $311.39
per core!
The otherwise identical CPU jumps to a whopping $11722, if you want to equip it with up to 1.5 TB of RAM instead of only 768 GB.

Adding to that, we recently renovated our supercomputer. We have almost 3500 dual-socket compute nodes. That's nearly 7000 24-core Xeon 8160. Other than 4 less cores per unit, its identical to Xeon 8176. I don't really know how much we paid for each Xeon, not even high management knows that, since we ordered the supercomputer as a whole to the best bidder.
The whole supercomputer is €34 million. €4 million are devoted to the disc system, and €30 million to the compute subsystem + some work on the electrical and cooling systems. The compute system includes the racks, the interconnection network, cabling (more than 50 Km of cabling) and several months installing and testing components. I assume most of the cost is due to the compute nodes.
As a guessing exercise, lets say that €25 million are devoted to the compute nodes, that is €7150 per node, which includes 2 sockets , motherboard, memory, SSD disc, redundant power source and router to connect to other nodes. Guessing again I would say that each Xeon 8160 should be somewhere around €2000-2500. Xeon 8160 is listed at $4702
