For a B580 225W (products are always designed around max TBP, not TDP) like GPU what’s a realistic cost estimate for components and specific subcomponents? Ignore GPU die and memory/VRAM in the math. My own estimates range wildly from $70-120 + GPU & VRAM, so really don’t know what to think.

Here is the template I’ve been using:

Components and Subcomponents

• GPU Die (BGA Package): GPU Die, BGA Package
• Memory: GDDRx, Memory Controller, DRAM ICs
• PCB (n-layer compact/normal): Base PCB, Copper Traces, Solder Mask, Silkscreen
• Cooling Solution: Heat Pipes, Fans, Fan Controller, Thermal Paste, Heatsink, Shroud & Backplate (Plastic), Screws & Holding Mechanism, Thermal Pads (VRM)
• Power Delivery (VRM Components): MOSFETs, Inductors, Capacitors, PWM Controller
• Connectors and Interfaces: HDMI 2.1a, DisplayPort 2.1, PCIe Connector
• Miscellaneous Components: Resistors, Capacitors, Inductors, Diodes, ICs (e.g., voltage regulators, logic ICs)

Cost Overhead

• Testing/Validation + Assembly: Testing and Validation, Assembly
• Packaging: ESD bag, foam, and cardboard box
• Transport: Transport
