Context Before
Source: SemiAnalysis Estimates
Below, we will go over the differences from our estimates back in April and the details of the Helio rack.
Evidence
Overall, this rack is a scale up domain of 72 GPUs just like Nvidia’s Oberon architecture, hence the UALoE72 (UALink over Ethernet 72) nomenclature.

② Atomic Claim
MI400 Helios/UALoE72 scale-up domain 為 72 GPUs，與 Nvidia Oberon 的 world size 相同。
