MASSIVE DELAY: Just 3 months after Jensen demoed Kyber NVL144 at GTC, it has faced major setbacks and has been delayed by more than 12 months, pushing it back to 2028. Below, we explain why Kyber has faced massive delays and why NVIDIA’s NVL72x2 back-to-back rack architecture was… pic.twitter.com/VYduxnu01B July 5, 2026. The orthogonal backplane sits between Kyber's vertically mounted compute trays and the switch trays behind them, replacing the cable harnesses of earlier racks with a rigid board that carries the all-copper NVLink fabric. Tom's Hardware is the main source layer for now, and the rest should be read as a signal that is still widening. On the device side, the useful angle is whether a technical change actually alters feel, lifespan, or upgrade cost in real use.
What is happening now
MASSIVE DELAY: Just 3 months after Jensen demoed Kyber NVL144 at GTC, it has faced major setbacks and has been delayed by more than 12 months, pushing it back to 2028. Tom's Hardware form the main source layer behind the core facts in this piece. This is still a developing thread, so the useful part is knowing which source signals are hardening and which ones still need caution. With devices, practical impact usually shows up in battery life, heat, stability, and long-term usability rather than in a few flashy headline numbers.
Where the sources line up

Tom's Hardware form the main source layer behind the core facts in this piece. With devices, practical impact usually shows up in battery life, heat, stability, and long-term usability rather than in a few flashy headline numbers. The readers who should care most are the ones planning to replace a device, buy an accessory, or upgrade a work setup in the next few months.
The details worth keeping
The orthogonal backplane sits between Kyber's vertically mounted compute trays and the switch trays behind them, replacing the cable harnesses of earlier racks with a rigid board that carries the all-copper NVLink fabric. On the device side, the useful angle is whether a technical change actually alters feel, lifespan, or upgrade cost in real use. The readers who should care most are the ones planning to replace a device, buy an accessory, or upgrade a work setup in the next few months. The next step is to see whether the current signals harden into a durable change or fade as a short-lived experiment.
Why this matters most
The signal is strong enough to deserve attention, but it still needs to be read as something developing rather than fully settled. With 1 source layers on the table, the part worth reading most closely is where firm facts meet the market's early reaction. Kyber runs liquid cooling by default and stacks 144 Rubin Ultra packages, double the 72 packages in a current Oberon NVL72 rack .
What to watch next
The next readout is price, device coverage, and whether the change feels real once the hardware reaches users. Patrick Tech Media will keep checking rollout speed, user reaction, and how Tom's Hardware update the next pieces. From 1 early signals, the piece keeps 1 references that are useful for locking the main details in place. That is why the useful reading move is not to stop at the headline, but to compare the promise, the workflow change, and the likely cost before deciding anything.
