Memory controllers are die area. mm2 die space is linear bom cost.
DRAM+mm2 bom will have a different slope to just DRAM bom but still basically linear. Nonlinear pricing is pure market segmentation.
- aurareturn 1y agoMemory controllers are die area. mm2 die space is linear bom cost. Ignoring the design and platform support that comes with higher bandwidth memory controllers.
- throwaway48476 1y agoAnd this is not also linear or fixed cost, why? I don't think you know how industry pricing works. Wafers have a price, double mm2, double the price of chip in bom.
- aurareturn 1y agoYes. Bigger die size. More complex memory controller designs. More memory lanes. More software support for higher memory lanes. All adds up. I'm explaining why despite memory being a commodity, high memory bandwidth VRAM cost is not cheap.
- throwaway48476 1y agoMemory controllers are copy paste. It's not more complex. It's more expensive in a linear way wrt bom.
