Unverified: Jukan Says Nvidia's Rubin Was Delayed Again, With Volume Shipments Slipping to 2027
Re: the rumor that NVIDIA cut orders One thing I’ve been able to confirm is that Rubin has been delayed again. I’m told motherboard warpage caused the latest delay and that the HBM issue was resolved in October. (As it happens, Korean media reported today that SK hynix’s HBM4 yield had reached 70%.) As a result, volume shipments of Rubin have slipped to 2027, and I’m told NVIDIA has increased its Blackwell orders in the meantime. Since posting about the rumored order cuts, I’ve spoken with several funds and supply chain contacts. One rumor making the rounds is that CCL orders were cut by 30%. One source I spoke with said that claim was false. I hope this helps. Thanks.
Context
Rubin is Nvidia's next data center platform, so a delay would shift AI compute plans and keep buyers on Blackwell for longer.
Jukan is a semiconductor analyst account that often relays supply chain reports. In this post he responds to rumors that Nvidia cut orders and says he confirmed a new Rubin delay through his own contacts. Nvidia has not commented, so the claim is unverified.
Deep dive
Jukan posted on November 12, in response to rumors that Nvidia cut orders, that one thing he was able to confirm is that Rubin has been delayed again. He says he was told that motherboard warpage caused the latest delay and that an HBM issue was resolved in October.
As a result, according to the post, volume shipments of Rubin have slipped to 2027, and Nvidia has increased its Blackwell orders in the meantime. Jukan also notes that Korean media reported the same day that SK hynix's HBM4 yield had reached 70%.
On the wider order cut rumors, he says he spoke with several funds and supply chain contacts. One rumor going around is that CCL orders were cut by 30%, but he says one source told him that claim was false.
This is an unverified claim from an analyst account citing unnamed sources. Nvidia has not confirmed any delay. Additional reporting, secondhand: an X news summary says Baird downgraded Nvidia to Neutral on November 11, citing limited visibility on 2027 data center demand and supply hurdles, ahead of the company's earnings on November 17.
What to expect next
Nvidia's earnings report on November 17 is the clearest place for the company to address Rubin timing, Blackwell supply and any order changes. Watch for confirmation or denial from Nvidia or its board and manufacturing partners such as TSMC, and for updates from HBM suppliers like SK hynix. A confirmed slip to 2027 would affect the compute roadmaps that labs and cloud providers have shared.
