Fermi question · Technology
About how many transistors are in an NVIDIA Blackwell-architecture GPU?
Make a fast, defensible estimate before you reveal the reference answer. Think in factors, not exact recall.

Reference answer

≈ 208 billion transistors
Fermi estimates are judged by scale, so a reasonable approximation can still earn a strong score.
One way to estimate it
Scale from large modern accelerator dies, which contain hundreds of billions of transistors.
- Advanced GPU scale≈ 10¹¹ transistors
- Two large dies in one GPUroughly doubles a 100B-class die scale
- Estimate≈ 2 × 10¹¹ transistors
