That's probably better explained by TSMC 7nm capacity rather 5nm capacity. I'm sure Nvidia would have preferred even TSMC 7nm over Samsung 8nm.

- kllrnohj 6y agoNvidia used TSMC 7nm for the first Ampere chip, the GA100 used in the HPC-focused A100. The density vs. the Samsung 8nm manufactured GA102 in the RTX 3090 & 3080 is drastic. 65.6M / mm² vs. 45.1M / mm². Either Samsung gave Nvidia a hell of a deal or TSMC's 7nm was booked up.
- tutanchamun 6y agoCould also be a bit of both. But I wouldn't be surprised if it's mainly Samsung giving Nvidia a great deal. For years it's all over town that Samsung seems to have the best wafer prices in the industry.
