description: "UBS: Vera Rubin BOM & Server CostsConventional Server BOM & Memory Cost Trends> Surging Memory Share: Memory now accounts for roughly 69% of the Bill of Materials (BOM) cost for a conventional data center server (loaded with 16 DIMMs of 64GB DRAM and 3.84TB NAND), a sharp rise from 40% in 2025.> Cost Escalation: Driven by rising DDR and NAND contract pricing, incremental memory costs alone are estimated to drive a 127% increase in overall conventional server costs (totaling $26,077 up from $11,513).> Component Breakdown:DRAM costs show a 315% YoY surge ($14,624 total, representing 56% of cost).NAND NVMe Gen4 costs show a 227% YoY increase ($3,379 total, representing 13% of cost).AI Server Superchip Memory Projections (GB300, VR200, VR300)> GB300 (2026): Total HBM3E and LPDDR5X costs per superchip are estimated at $9.7k (53% to 58% of total cost), translating to approximately $350k per rack.> VR200 (2026–2027): Combined HBM4 and SOCAMM2 costs sit at $24.3k (62% of cost) in 2026, climbing to 70% of the total in 2027. Per-rack memory costs move from $875k in 2026 to $1.143m in 2027.> VR300 (2027): Assuming 756GB HBM4E 12-Hi and SOCAMM2, superchip memory costs could reach $35.5k (77% of total superchip cost), driving per-rack memory costs to a massive $1.273m.Macro Rack-Level Trajectory> Milestone Threshold: Total memory costs are projected to comfortably exceed US$1 million per Vera Rubin rack by 2027.> Structural Shift: Across the AI server lineup, total memory costs as a percentage of the overall stack continue a heavy upward trajectory, moving from an already substantial 58% for the GG300 up to 77% for the VR300.For reference, this is from late May. $NVIDIA(NVDA.US) $Micron Tech(MU.US) $DRAM $EWY"
