Evidence
The second benefit is a reduction in cost stemming from eliminating almost all transceivers. There is even more room for price reduction if we are looking at NVIDIA LinkX transceivers, which tend to be priced at significant premium to their generic equivalent. If we compare total networking costs for a 3-Layer network with and without CPO-based switches in the scale-out domain, we see an average of ~75% reduction in transceiver costs. However, as with the power savings above, such costs savings tend not to move the needle dramatically considering the full cluster costs.

② Atomic Claim
比較 scale-out domain 使用與不使用 CPO-based switches 的 3-layer network，採用 CPO 後 transceiver cost 平均約可降低 75%。
