HBM MEMORY PRICE · AI ACCELERATOR MEMORY

HBM memory price — HBM3, HBM3E and HBM4 per stack

Per-stack and per-GB reference pricing for the memory bolted to every AI accelerator.

Quick answer: as of 2026-08-28, HBM3 24GB 12-Hi Stack is $200.40 USD / stack, +0.01% over 30 days and +4.00% year over year. Across the 6 contracts tracked on this page the basket is +3.91% over 30 days and +172.17% year over year.

HBM is the reason the rest of the memory market is on fire. It is an allocation product with no open spot market, so tracked levels come from supply-chain reporting and supplier disclosures rather than a daily survey. Each row is flagged reported, derived or estimate and links to its source.

HBM price per GB by generation

Stack price divided by stack capacity, so generations — and HBM versus commodity DRAM — compare on one basis. As of 1970-01-01.

    SK hynix drops 5% after approving $38B of new memory fabs; Seagate falls 7%

    Memory and storage names sold off after SK hynix approved a $38B fab program, with investors reading the spend as the first credible path back to oversupply. New front-end capacity takes 7-9 quarters to produce bits, so the risk lands in 2027-28, not this quarter.

    CXMT eyes a second Beijing DRAM plant as China pushes toward Micron-scale output

    CXMT is reported to be planning a second Beijing DRAM fab, targeting output approaching Micron's by late 2026. Chinese commodity DDR4/DDR5 supply is the single largest downside risk to the conventional-DRAM price curve.

FAQ

How much does an HBM stack cost?
As of 1970-01-01, tracked HBM levels run from roughly the HBM3 24GB stack at the low end to HBM4 48GB at the high end — the exact figures, per stack and per GB, are in the tables above. HBM is sold on multi-quarter allocation rather than an open spot market, so these are indicative reference levels drawn from supply-chain reporting, not exchange prices.
What is the HBM3 price today?
The HBM3 24GB stack row above carries the current tracked level with its 30-day and year-over-year change. HBM3 is the previous-generation part now largely displaced by HBM3E in new accelerator builds, so its pricing tracks residual demand and remaining allocation rather than fresh contracts.
How much does HBM cost per GB versus normal RAM?
The per-GB table above divides each stack price by its capacity. HBM typically lands an order of magnitude above commodity DDR5 on a $/GB basis, because stacked dies, through-silicon vias and advanced packaging all add cost the mainstream part never pays.
Is there an HBM memory price chart?
Yes. Every HBM row links to a dedicated 12-month chart, and the price explorer on this page plots HBM3, HBM3E and HBM4 together — indexed or in absolute dollars — alongside DDR5 and GDDR6 so you can compare generations on one axis.
Why is HBM so expensive compared with DDR5?
HBM stacks DRAM dies vertically with through-silicon vias and requires advanced packaging next to the accelerator. Stacking yields are low, packaging capacity is constrained, and demand is effectively unlimited relative to supply.
Who makes HBM?
SK hynix, Samsung and Micron supply essentially all HBM going into Nvidia, AMD and hyperscaler accelerators. The manufacturer leaderboard ranks them by HBM share, bit share, revenue, backlog and capex.
How does HBM demand affect regular RAM prices?
HBM consumes roughly three times the wafer area per shipped bit versus commodity DDR5, so each wafer converted to HBM removes several times more mainstream bits from the market. That is the core mechanism behind the DDR5 and DDR4 price surge.
Will HBM prices come down?
Not while accelerator demand outruns packaging capacity. HBM4 pricing is set in allocation negotiations a year ahead, so the first sign of softening usually appears in the older generation — a sustained negative 30-day print on HBM3 before HBM3E or HBM4 move.
