NVIDIA Rigel Core: Single-Threaded CPU as the New Control Plane for Agentic AI
NVIDIA unveils Rosa CPU architecture with custom Rigel core (Arm v9.2), targeting single-threaded performance for Agentic AI workloads, paired with Feynman GPU (1.6nm, 50 PFLOPS) in 2028. This shifts CPU design from core-count scaling to serial-latency optimization, directly challenging AMD EPYC and Intel Xeon dominance.
NVIDIA Denies Kyber NVL144 Delay, But 78-Layer PCB Bottleneck Exposes AI Hardware Physics Limit
NVIDIA officially denies reports of Kyber NVL144 rack delay to 2028, but SemiAnalysis revelations about a 78-layer ultra-high-density PCB midplane bottleneck and Rubin Ultra cancellation expose hard physical limits in signal integrity and manufacturing, opening a strategic window for AMD and Google.
NVIDIA Kyber NVL144 Delayed to 2028: Midplane PCB Manufacturing Becomes AI Scaling Bottleneck
SemiAnalysis reveals NVIDIA's Kyber NVL144 delayed beyond 12 months to 2028 due to 78-layer Orthogonal Backplane manufacturing challenges. The interim NVL72x2 solution is cancelled due to operational burdens, and the 4-die Rubin Ultra is also scrapped, leaving a product gap in NVIDIA's scaling roadmap.
