[Institutional Research Report Reveals Significant Delays in Two Key Technical Paths for AI Data Centers] BlockBeats News, June 10 — Independent research institution SemiAnalysis, which focuses on semiconductors, AI infrastructure, and data center fields, released its latest multi-vertical research note today. The core conclusion points to significant delays in two key technical paths for AI data centers. The first is the substantial delay in the shipment of NVIDIA's native 800VDC architecture. The report states that NVIDIA's originally planned large-scale adoption of the single-ended 800VDC power design has now been postponed to 2028. While the 400VDC high-voltage direct current solution is still progressing as planned, hyperscalers (large-scale cloud providers) currently prefer to continue using mature low-voltage solutions or gradually transition to 400VDC rather than rushing to switch to 800VDC. The report highlights that the marginal benefits of 800VDC in terms of current power grid supply and efficiency improvements are insufficient to justify its complexity, causing the industry to temporarily slow down its pace. The second is the slowdown in the production and delivery pace of CPO (Co-Packaged Optics). The expected shipment volume of CPO in 2027 is significantly lower than previous aggressive market forecasts, with large-scale production potentially delayed to 2028 or even 2029. The shipment volume of scale-out CPO switches faces downward adjustment risks, primarily due to bottlenecks in optical engine connection yield, ASIC integration challenges, and overall cost-effectiveness. Currently, the optimistic yield for optical engine connections is around 95%, but the CPO output driven by a single ASIC remains very limited. SemiAnalysis indicates that 400VDC products are expected to ramp up starting in Q2 2026, with significant growth in 2027; some NPO (Near Package Optics) projects may accelerate progress. However, the downside is that shipments relying on new platforms like Rubin Ultra/Kyber sidecars will be delayed to the 2028 window, putting pressure on related power supply, switch, and optical module suppliers. SemiAnalysis maintains a relatively positive outlook on companies such as Amphenol, Vertiv, and Legrand, while adopting a more cautious stance toward Lumentum, Himax, Navitas, and Wolfspeed.
