HBM4 price — 48GB stack cost and premium over HBM3E
The next high bandwidth memory generation, priced per stack and per gigabyte.
Quick answer: as of 2026-10-12, HBM3 24GB 12-Hi Stack is $200.17 USD / stack, +0.20% over 30 days and +4.00% year over year. Across the 4 contracts tracked on this page the basket is +0.74% over 30 days and +124.50% year over year.
HBM4 widens the interface to 2048 bits and adds a logic base die, moving part of the stack onto a foundry logic process. That changes the cost structure of high bandwidth memory and pulls a second supply chain — advanced packaging and foundry — into memory pricing.

17 Sep spot board: DDR5 averages $55.23; DDR4 16Gb retreats 1.85%
DDR5 16Gb 4800/5600 averaged $55.233 (+0.73%) and DDR5 eTT averaged $24.50 (+0.82%). DDR4 split: 8Gb 3200 rose 0.78% to $46.143 while 16Gb 3200 fell 1.85% to $86.00. The board remains historically expensive, but the first visible corrections are appearing in select legacy parts.

512Gb TLC NAND slips to $20.083 as consumer buying stays weak
The 512Gb TLC wafer spot reference fell another 0.31% to $20.083 on 14 September after a 2.71% weekly decline to $20.146. Consumer purchasing remains cautious even while enterprise SSD demand keeps contract pricing elevated.

Spot board, 1 Sep: DDR5 16Gb $54.08, DDR4 16Gb $92.02, DDR4 8Gb $44.54 — all up under half a percent
The 1 September session closed with DDR5 16Gb 4800/5600 at a $54.083 average (+0.31%), DDR4 16Gb 3200 at $92.024 (+0.27%) and DDR4 8Gb 3200 at $44.544 (+0.40%). Every line is still green, but the daily session moves are now fractions of a percent rather than the multi-point jumps of June and July. The spread is the story: DDR4 16Gb printed a $117.00 high against a $42.20 low in the same session.

FAQ
- What is the HBM4 price?
- As of 1970-01-01 the tracked HBM4 48GB stack level and its per-GB equivalent are in the table above. HBM4 is priced in forward allocation negotiations roughly a year ahead of shipment, so the level reflects contract economics, not a tradeable spot market.
- How much more expensive is HBM4 than HBM3E?
- The comparison table on this page shows the current premium per stack and per GB. HBM4 doubles the interface width and adds a logic base die, both of which raise cost before yield effects are counted.
- Why does HBM4 cost so much?
- A 2048-bit interface, a custom logic base die often built on a foundry logic node, more stacked dies, and hybrid bonding at the leading edge. Each of those steps has lower yield than the equivalent in HBM3E, and advanced packaging capacity is the binding constraint industry-wide.
- When does HBM4 ramp in volume?
- HBM4 is ramping into next-generation accelerator platforms, with supplier qualification the gating factor rather than raw wafer capacity. Watch the 30-day column here against HBM3E: the two converging is the signal that HBM4 supply has caught up with the platform ramp.
- Who will supply HBM4?
- SK hynix, Samsung and Micron are all qualifying HBM4, with foundry partnerships for the logic base die reshaping the competitive order. The manufacturer leaderboard tracks HBM share and capex for each.
