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 cost savings from copper more than offset the additional cooling overhead
