Claims
- The AI infrastructure race increasingly depends on power efficiency, not only raw GPU performance.
- Nvidia's co-packaged optics technology integrates light-based data transfer directly with GPU chips.
- CPO reduces wasted power in GPU-to-GPU communication in AI data centers.
- Nvidia demonstrated the CPO switch in collaboration with Lambda.
Key quotes
The AI race is not only about stronger GPUs, but about wasting far less power while those GPUs talk to each other.
With co-packaged optics (CPO), NVIDIA is putting the light-based [data transfer directly with GPU chips].
