Question Calculating the cost of Nvidia's Blackwell Chip ?

[Luke1977]

Hey all,

I am trying to figure out the Blackwell chip price.

1. According to Wikipedia the chip is 28 x 28, so I took this information into this die per wafer calculator and found out there are 67 dies per wafer (link: https://anysilicon.com/die-per-wafer-formula-free-calculators/)

2. The price per wafer (4NP) is ~15K according to this page: https://anysilicon.com/wafer-cost/

3. For now, I will assume the yield is 50%

4. The price per die is ~$450

Is this correct?

Thanks for your answers.

Keep in mind you’re talking about nvidia who seems to act like their products are gold at times lately.

50% Yield meaning that from 67 dies only 33 or so dies will actually be functionally useful leading to:

$15,000/ 33 being the ~$450. Correct?

How much + or - variance in Yield % is acceptable?

Is there any concern or requirement with respect to broader statistical results?

Overall concern/question being that the presented calculations and results may be over-simplified.

Will leave that to the more statistically inclined folks.
