Nvidia's Kyber AI Rack Delayed to 2028
Research firm SemiAnalysis reports that Nvidia’s Kyber NVL144 rack‑scale architecture — designed to house Rubin Ultra chips — has been delayed to 2028 due to manufacturing challenges with a specialized multi‑layer printed circuit board (PCB midplane). SemiAnalysis also says the larger NVL576 system is likely delayed or limited to small volumes, and that a proposed fallback (bolting two current racks together) was cancelled after cloud providers pushed back. The delay raises concerns that Nvidia’s fast product cadence is colliding with manufacturing limits and could create a technical opening for rivals such as AMD and Google. Nvidia’s current Rubin systems remain in production and are slated to ship this fall to cloud partners including Amazon Web Services, Microsoft Azure and Google Cloud.
Delay of Nvidia's next‑generation rack has implications for AI compute capacity, cloud deployments and competitive dynamics — potentially enabling rivals (AMD, Google) to gain share at the high end and affecting timelines for large model training and inference.

Key Takeaways & Evidence Grounding
- SemiAnalysis reported Kyber NVL144 rack architecture delayed to 2028 due to PCB midplane manufacturability challenges.
- SemiAnalysis said NVL576, a larger system linking eight racks, is also likely delayed or limited to small volumes.
- A proposed backup plan of bolting two current Nvidia racks together was cancelled after pushback from cloud service providers and hyperscalers.
- Nvidia’s current‑generation Rubin systems are in production and expected to begin shipping this fall to cloud partners including Amazon Web Services, Microsoft Azure and Google Cloud.
- SemiAnalysis projects Nvidia’s data‑center compute revenue will run about 20% above Wall Street consensus in the second half of fiscal 2027.

Nvidia's Growth Soars as Vera Rubin Hits Market
Nvidia reported another quarter of rapid growth and issued an optimistic forecast driven by AI data-center demand and the rollout of its next rack-scale system, Vera Rubin. The company expects year-over-year revenue to rise about 77% this quarter to roughly $78 billion, beating analyst estimates, and said data center sales now represent over 91% of revenue. Nvidia began shipping first Vera Rubin samples and says Rubin’s 72 next-generation GPUs will deliver about 10x more performance per watt versus predecessors. Management flagged supply commitments into 2027 and raised its addressable opportunity tied to Blackwell and Rubin. Competitors and risks cited include AMD’s upcoming Helios rack system (with Meta committing AMD GPUs) and large cloud customers building in-house chips; Nvidia is not assuming any China data-center revenue in its near-term outlook due to export-control uncertainty.
Nvidia Sees $1T Orders for Blackwell and Vera Rubin
At GTC 2026 Jensen Huang framed a shift from chip-focused competition to a token-and-agent economy, positioning OpenClaw as a new software substrate while announcing Nvidia’s Vera Rubin data-center system and a purpose-built Vera CPU for agentic AI. Nvidia demonstrated a jump in token decoding throughput (from ~2 million to ~700 million tokens/second in a ~1GW data center), discussed token-pricing tiers (~$3–$150 per million tokens), and emphasized token-per-watt as a key efficiency metric. The newsletter ties these announcements to broader industry signals: a Harvard-backed study showing supervision of AI agents raises cognitive load and error rates; viral deepfake distrust around a Netanyahu livestream; OpenAI delaying an “adult mode” over moderation and age-detection limits (12% misclassification in tests, ~100M underage weekly users cited); and TL;DR items including Mistral’s open-source Small 4 model, lawsuits by Encyclopaedia Britannica and Merriam‑Webster against OpenAI, Shopify’s AI shopping‑agent investments, and a reported Nebius–Meta compute deal.
Nvidia's Vera Rubin: 10x More Efficient AI System Unveiled
Nvidia unveiled details and gave CNBC a first look at Vera Rubin, a new rack-scale AI system it says will deliver roughly 10 times the performance per watt of its predecessor, Grace Blackwell. Vera Rubin is a modular, fully liquid‑cooled rack expected to ship in H2 2026; each rack contains 72 Rubin GPUs and 36 Vera CPUs and about 1.3 million components sourced from 80+ suppliers across 20+ countries. Nvidia says the design simplifies maintenance (hot‑swap superchips) and boosts energy efficiency despite higher absolute power draw. Major cloud and AI customers — including Meta (which committed to use Vera Rubin by 2027), OpenAI, Anthropic, Amazon, Google and Microsoft — are expected users. The article notes supply‑chain pressures on memory pricing, competitive pressure from AMD (Helios) and others, and Nvidia’s plan to manufacture large amounts of U.S. AI infrastructure through 2029.
