Context Before

Nvidia has indicated that Vera Rubin increases liquid flow rate and achieves nearly double the thermal performance vs Blackwell, without increasing CDU pressure head or introducing additional cooling complexity or cost.

Evidence

Nvidia has achieved this by optimizing the entire hydraulic path.

Context After

We expect larger quick disconnects to support higher flow, as well as updated manifolds and piping.

② Atomic Claim

Nvidia 透過最佳化整條 hydraulic path 達成這項結果。
