NVIDIA shipments stay Blackwell-led as Rubin's ramp slips into next year on HBM4 snags, keeping HBM the key bottleneck.

Key Highlights

Mix: Blackwell dominates NVIDIA GPUs; Rubin's share slips on readiness delays.
Outlook: Rubin ramps next year, turning mainstream; Rubin Ultra stays small at first.
Bottleneck: Low HBM4 yields constrain chip shipments.
Spec: Suppliers weigh a 12hi-to-8hi HBM4/4e shift to boost yield.
