Evidence

For Rubin Ultra NVL144 Kyber, there will be no CPO used for scale up, despite rumors from other analysts suggesting scale-up CPO introduction for Kyber.

Context After

However, optics for NVLink are coming and will be progressively phased in. Scale-up CPO will first be used for the Rubin Ultra NVL576 system to connect between 8 Oberon form factor racks, forming a two-layer all-to-all network.

② Atomic Claim

對 Rubin Ultra NVL144 Kyber 而言，scale-up 不會使用 CPO；這與其他分析師傳出的 Kyber 將導入 scale-up CPO 的說法不同。
