NVIDIA Rubin Chip Slightly Delayed Due to Thermal Issues, Mass Production Starting July
nashnova research
Nvidia's next-gen Vera Rubin GPU hit a minor delay over a server thermal-lid design flaw — now fixed — with KeyBanc expecting volume production to begin in July and full-year shipment forecasts unchanged.
What exactly went wrong?
The Rubin GPU's server thermal lid — a metal cap sitting on the chip to draw heat away — had a design flaw that caused a slight production delay.
KeyBanc analyst John Vinh, citing Asia supply-chain sources, confirmed the issue is resolved; current signs point to a July volume ramp.
Nvidia had not commented as of the report's publication.
Did the full-year outlook change?
Vinh kept his full-year forecasts intact: 1.7–1.8 million Rubin chips and 5.5–6.0 million Blackwell chips.
This means → the delay is a week-scale tweak, not a directional shift in the product cycle; the supply-chain cadence remains on track.
He also raised his Nvidia price target from $310 to $330, maintained an outperform rating, and based the target on a 25× P/E on KeyBanc's fiscal-2028 earnings estimate.
Where is Nvidia's moat?
Vinh argues Nvidia's CUDA software stack — its proprietary GPU programming platform that developers find hard to leave once adopted — creates a formidable barrier to entry, limiting competitive risk.
In plain terms = customers buying Nvidia chips aren't just buying hardware; they're locked into an entire software ecosystem — making it very hard for rivals to win on specs alone.
He expects Nvidia to keep dominating cloud and enterprise AI workloads, the fastest-growing segment in semiconductors.
How did the stock react?
Nvidia rose 1.2% pre-market Tuesday to $206.05, with a year-to-date gain of roughly 9.1% — lagging the broader semiconductor sector.
This reflects a notably calm market response to the delay; the uptick suggests investors focused more on the price-target raise and unchanged shipment outlook.
The key watch-items ahead: whether the thermal fix holds on schedule and whether the July volume-production milestone is met — both will validate whether the Rubin cycle is tracking as expected.
