Context Before
While Feynman adopting CPO is on the roadmap, the question is to what extent? Will in-rack interconnectivity be copper based or optical? We will show possible configurations behind the Paywall. Vera ETL256
CPU demand is rising as AI workloads require more data handling, preprocessing, and orchestration beyond GPU compute. Reinforcement learning further increases demand, with CPUs running simulations, executing code, and verifying outputs in parallel. As GPUs scale faster than CPUs, larger CPU clusters are needed to keep them fully utilized, making CPUs a growing bottleneck.
Evidence
The underlying rationale mirrors the NVL rack design philosophy: pack compute tightly enough that copper interconnects can reach everything within the rack, eliminating the need for optical transceivers on the spine

② Atomic Claim
其設計邏輯與 NVL rack 相同：把運算元件塞得足夠密集，使 copper interconnect 能涵蓋整個機櫃，因而不需要在 spine 使用 optical transceivers。
