Context Before

Evidence

Since the announcement of GB200 at Nvidia GTC 2024, the concept of an AI server system has shifted from a chassis to a rack scale system.

Context After

In our GB200 article, we discussed the evolution of Nvidia AI server form factor from HGX (8 GPU per node) to Oberon (NVL72 rack scale). While the HGX form factor still exists, the majority of Nvidia’s Blackwell GPUs are integrated in the Oberon form factor. Rubin will also be offered in both HGX and Oberon systems.

② Atomic Claim

自 Nvidia 在 GTC 2024 發表 GB200 後，AI server system 的概念已從 chassis 轉向 rack-scale system。
