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
Each compute tray contains four MI400 GPUs, while each switch tray contains two Tomahawk 6 102.4T Ethernet switches running at 200G per lane.
Context After

② Atomic Claim
Helios 每 compute tray 含 4 顆 MI400 GPU；每 switch tray 含 2 顆 102.4T Tomahawk 6 Ethernet switches、200G/lane。
