Nvidia's Kyber Rack Delayed to 2028 Amidst Technical Challenges
Nvidia's highly anticipated Kyber NVL144 rack, designed for its Rubin Ultra GPUs, is reportedly facing a significant delay, with shipments now expected in 2028. This pushes back the availability by over 12 months from its initial projected timeline. The delay is attributed to persistent issues with the Printed Circuit Board (PCB) midplane, according to an analysis by the firm SemiAnalysis. Furthermore, a proposed stopgap solution intended to bridge the gap until the Kyber rack's full deployment has also been canceled. This cancellation is reportedly a direct result of substantial pushback from Nvidia's customers, indicating dissatisfaction with the alternative. The technical hurdles with the PCB midplane appear to be the primary driver behind both the delay of the main product and the axing of the interim measure.
The reported delay of Nvidia's Kyber NVL144 rack to 2028, stemming from PCB midplane challenges, highlights the complex engineering and supply chain hurdles inherent in scaling advanced AI hardware. Customer pushback on interim solutions suggests a critical need for reliable, high-performance infrastructure that meets evolving demands. This situation underscores the delicate balance between rapid innovation and manufacturing readiness, particularly as the industry races to support increasingly powerful AI models. Future strategies may need to incorporate more robust pre-production testing and flexible supply chain management to mitigate such delays and maintain market confidence.
