NVIDIA denies Kyber NVL144 delay reports; roadmap remains intact for H2 2027 launch
On July 6, NVIDIA pushed back against SemiAnalysis reports claiming a 12+ month delay for Kyber NVL144 racks to 2028. An NVIDIA spokesperson stated, 'Our roadmap is intact,' in response to claims that manufacturing challenges with a 78-layer PCB midplane (called the 'orthogonal backplane') would prevent the vertical-rack system from shipping alongside Vera Rubin Ultra. The stock rose 0.37% on the denial.
Kyber NVL144 is designed to double GPU density from 72 to 144 units per rack using a novel vertical compute-tray arrangement, with first deployment alongside Rubin Ultra in H2 2027. SemiAnalysis also alleged that NVIDIA cancelled the backup NVL72x2 design after cloud providers rejected it as operationally cumbersome, and that larger NVL576 8-rack systems may face delays due to co-packaged optics (CPO) manufacturing challenges. NVIDIA offered no further commentary.
For infrastructure architects tracking NVIDIA's roadmap, this denial matters because Kyber represents the next major architectural leap after Rubin (shipping H2 2026). Any 12-month slip would give AMD MI500X and Google TPUv8i rare competitive openings at hyperscaler scale. NVIDIA's terse response and quick rebuttal suggest confidence, but watch Q3 earnings guidance for supply chain color and cloud customer order signals to confirm the timeline holds.
