A 4090 die costs around $200 to produce so not sure how we get from that to $1600.
i think its more close to 300.. i base that on 50-60% yields and a small premium on node customization, i believe TSMC has to spend efforts on PDK customization, interoperability issues, specific compliance etc. and that get priced into the final offer
so lets assume nvidia is targeting a 50% gross margin, the selling price becomes $600 to AIBs..
then you'd have inward logistics and AIB margins on that.. let' say it works out to 15% - so the price of the chip jumps to $706 when it hits the AIB outbound WH
now youd have to add distributor margins.. maybe 7% including inward logistics, $759 when it hits the distributor WH
same again for retailers.. around 5% including logistics, retailers work on thin margins, so $800 by the time it reaches end consumers
and this is just the chipset, so you'd have to further had vram chips, board, cooler etc... the coolers on FE are supposed to expensive, like $150-200 thats what i remember from Ampere leaks, so nvidia isagain going to double that to $300 in line with their margins..
maybe it would fall short of 1599 but its not going to be a big number
