OpenAI 3nm chip

[Jawar74]

Hey all,

Again its me with the same price exercise!

I am trying to figure out the OpenAI chip price.

1. I have assumed the chip size is 30x30, so I took this information into this die per wafer calculator and found out there are 60 dies per wafer (link: https://anysilicon.com/die-per-wafer-formula-free-calculators/)

2. The price per wafer (3nm) is ~20K (assumption)

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

4. The price per die is ~$600

Is this correct?

5. will the package cost the same? e.g $600

Thanks in advance for your answers

Thanks for your answers!

Is there any particular reason you assumed it's 30x30 per chip?

Did you also post another estimate that the chip was 28 x 28 here?

This seems like a lame promotion for AnySilicon. The poster is from salesacrobat.com. The first time, shame on them. The second time shame on me.
