Calculating Nvidia Chip Cost

[Jawar74]

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.

Thanks for your answers.

If you want the die price contact Techinsights. They know the numbers. Everything else, including anysilicon calculators, is nonsense. 50% yield is a low number for TSMC. If you are going to use a gross calculation with these software toys use a minimum of 60%. People who know yield and die cost find this type of thing entertaining so thank you.

50% for a large die isn’t bad. What matters is the DD
