Context Before

Though not officially discussed by Nvidia at GTC 2026, an NVL288 concept has been explored within the supply chain.

Evidence

This would entail two NVL144 Kyber racks placed adjacent to each other

Context After

, with a rack-to-rack copper backplane used to connect the two racks. One possibility is that all 288 GPUs are connected all to all, but this would require higher radix switches than the current NVLink 7 switches which only offer a maximum radix of 144 ports of 200G.

② Atomic Claim

此概念會將兩個 NVL144 Kyber racks 並排放置。
