HBM price tracker: the memory that caused the shortage

HBM prices: frequently asked questions

How much does HBM cost per GB?

About $12.00 to $12.80 per gigabyte for HBM3E and about $16.00 for HBM4, converted from the per-gigabit contract prices of $1.50 to $1.60 and $2.00 that DigiTimes reported in July 2026. A gigabyte is eight gigabits, so the conversion is arithmetic rather than an estimate. These are supply prices negotiated with AI chipmakers, not retail prices, and no one sells HBM to consumers.

Is HBM more expensive than regular DDR5?

Per gigabyte, and comparing an AI supply contract with a consumer retail listing, no: HBM3E at $12.00 to $12.80 per GB is below the $15.93 average for a retail DDR5 kit. That comparison crosses two very different channels, so treat it as a striking fact rather than a like-for-like price. The reason HBM drives the shortage is not its price per gigabyte but its margin per wafer: a wafer committed to HBM earns a memory maker far more than the same wafer committed to mainstream DRAM, so the capacity moved and everything else went short.

Why is HBM causing a DRAM shortage if it is a different product?

Because it competes for the same fabs and the same wafers. HBM is built by stacking standard DRAM dies, so every wafer that goes into HBM is a wafer that did not become a server DIMM or a desktop module, and the stacking process consumes more wafer per usable gigabyte than a flat module does. Add the AI build-out buying every stack available and the arithmetic is unavoidable: prioritizing HBM shrinks mainstream DRAM supply even though the two products sit in different markets.

Are HBM prices going up or down?

Up. Samsung and SK hynix raised HBM3E supply prices by nearly 20% for 2026, which was itself unusual for a generation that had already gone mainstream and would normally be getting cheaper. HBM4 is forecast to move from about $2.00 per gigabit in the second half of 2026 to $4.00 to $5.00 or more in 2027. As long as that is where the margin is, mainstream DRAM stays the lower priority.

What does HBM pricing mean for the price of my next PC upgrade?

It sets the floor under everything else. As long as HBM earns more per wafer than mainstream DRAM, memory makers have no commercial reason to flood the consumer market, which is why the forecasts cluster on late 2027 at the earliest rather than on any near-term relief. Practically: plan around today's retail prices, take the DDR4 discount if your platform allows it, and treat HBM contract pricing as the leading indicator of whether consumer supply is about to loosen.
