NVIDIA's Rubin Ultra Rack Estimated To Cost $21 Million, With HBM4e Memory Alone Swelling To $1.5 Million Per Unit
NVIDIA's upcoming Rubin Ultra racks have an estimated cost of $21 million, largely attributed to the increased prices for HBM4e memory, which alone can reach $1.5 million per unit. The projections by BofA Global Research highlight a significant escalation in production costs, particularly when compared to previous generation Blackwell servers. Notably, the HBM costs for these new racks have surged, exceeding previous benchmarks and indicating a substantial shift in the landscape of AI infrastructure investments.
