NVIDIA G-SYNC HDR display component costing over $500?

PC Perspective is raising some eyebrows with its teardown analysis of the ASUS ROG Swift PG27UQ display. As you may know, this is one of the first 27-inch 4K 144Hz G-SYNC HDR displays, even though it can't actually achieve 4K 144Hz because that's outside the specifications of DisplayPort 1.4.

Anyway, the screen costs a massive $1,999 and it seems a big chunk of this cost is due to the NVIDIA G-SYNC HDR support. In its review, PC Perspective estimates the new G-SYNC module from NVIDIA has a production cost of at least $500.

G-SYNC HDR isn't a small chip, it's actually a chunky module that features the Intel Altera Arria 10 GX 480 FPGA as well as 3GB DDR4-2400 memory:

It's an unstocked item, without a large bulk quantity price break, but you can actually find this exact same FPGA on both Digikey and Mouser, available to buy. It's clear that NVIDIA isn't paying the $2600 per each FPGA that both sites are asking, but it shows that these are not cheap components in the least. I wouldn't be surprised to see that this FPGA alone makes up $500 of the final price point of these new displays, let alone the costly DDR4 memory.
