DDR4 Costs More Than DDR5 — Unless You're Actually Buying It
You have probably seen the headline: legacy DDR4 now costs more than newer DDR5. Then you open a price comparison site to actually buy a stick, and the tags are the other way round. DDR5 is far more expensive.
Both numbers are real. They are just measuring different things, and the distance between them says something about how strange this memory market has become.
KEY TAKEAWAYS
1. On July 1, 2026, spot quotes put a DDR4 16Gb die at $74.63 against $46.83 for DDR5 16Gb — DDR4 59% higher.
2. That same month, Korean retail averaged about $151 for a DDR4 16GB module and $244 for a DDR5 16GB module — DDR5 61% higher.
3. Different units (one die vs one module) and different markets (spot vs retail). The two figures cannot be converted into each other, and reporting that treats a "16Gb" quote as a module price is off by a factor of eight.
Two numbers, both true
Start with the chip. On DRAMeXchange spot on July 1, 2026, the DDR4 16Gb average was $74.63 — 59.3% above the $46.83 average for one-generation-newer DDR5 16Gb. DDR4 8Gb sat at $36.10.
Now the shelf. Danawa's monthly average retail price for Samsung modules in Korea:
| Module | Jan 2026 | May 2026 | Jul 2026 |
|---|---|---|---|
| DDR4 16GB | $148 | $167 | $151 |
| DDR5 16GB | $236 | $233 | $244 |
| DDR5 32GB | $517 | $494 | $534 |
Won converted at each month's average KRW/USD rate from FRED EXKOUS (Jan 1,455.50 · May 1,488.40 · Jul 1,486.01).
Per gigabyte that works out to roughly $9.5 for DDR4 and $15.3 for DDR5. Against early 2025, DDR4 is up about 4.5x and DDR5 about 4.7x.
So here is the thing worth saying plainly: the headline "DDR4 is more expensive" is about chips, not about what you buy. Some coverage writes the spot quote as a "16Gb module", which conflates two units. Gb is a die capacity; GB is a module capacity. One letter, eight times the number.
Why they point opposite ways
The unit differs. A "16Gb" spot quote is one die — 2GB of capacity. A "16GB" retail tag is a finished module built from several of those dies on a PCB. They were never the same object.
The market differs. Most DRAM moves on contracts between makers and large customers. Spot is a thin market for buyers scrambling for inventory, so scarcity lands there first and hardest. In that same July, DDR4 8Gb was $21 on contract (June average) and $36.10 on spot — 71.9% apart, for the same chip.
The lag differs. A DDR4 module on a shelf was built earlier and is already sitting in the channel; today's die quote does not reach that price tag today. DDR5 is being manufactured and sold now, so input costs pass through immediately.
DDR4 chips are not expensive because they are wanted
They are expensive because there is nowhere left to make them. As wafers moved to HBM and DDR5, the DDR4 capacity went with them.
▶ Samsung — originally planned a Q4 2025 end of life, then signed non-cancellable, non-returnable (NCNR) deals with some server customers from Q1 2026, pushing the date out. (DigiTimes, Dec 24, 2025)
▶ SK hynix — says no discontinuation date has been officially set and that it will keep serving customers over the medium term. Industry sources expect output to fall between Q1 and Q2 2026.
▶ Micron — cited final shipments "in the next two to three quarters" on an earnings call, while continuing to serve long-term automotive, defense, industrial and telecom customers.
ADATA chairman Simon Chen put it bluntly: all three global makers have already closed and dismantled their DDR4 lines, so raising DDR4 output is effectively impossible. TrendForce reads the Fab 6 expansion as relocating and redeploying existing Taiwanese equipment rather than adding capacity, so the effect on global DDR4 supply is limited.
Which matters for how this unwinds. A price driven by vanishing supply does not fall the way a price driven by hot demand falls. A demand-driven price comes back down when demand cools. A supply-driven one has nowhere to come back to unless the lines restart.
Switching is not a one-part decision
DDR4 and DDR5 have different pin counts and notch positions, so they physically do not fit each other's slots. A DDR5 module also carries a power management IC on the module itself and splits into two 32-bit sub-channels. The bill of materials is not the same product.
So moving from DDR4 to DDR5 means replacing RAM, motherboard and CPU together. Comparing stick prices alone gives the wrong answer.
AM4 (Ryzen 5000) and LGA1700 (Intel 12th-14th Gen) are the last sockets that take DDR4. AM5, LGA1851 (Core Ultra 200S) and the LGA1954 platform for Nova Lake, due in 2026, are DDR5 only. AMD has said it will support AM5 through 2029. One PC-maker source told ZDNet Korea that with DDR4 and DDR5 CPUs both climbing in price, there is no longer a reason to hold out for DDR4.
When prices spike, fraud follows
In May 2026 PCWorld reported counterfeit DDR5 SO-DIMMs with plastic dummy chips glued to the board turning up in Japanese online listings. Buyers only noticed after installing them, and one had to cut the "chips" open to confirm. The steeper the price curve, the more of these appear.
What I actually watch
| Signal | Why |
|---|---|
| Contract-to-spot gap narrowing | A 71.9% spread is panic pricing; closing it means spot is cooling |
| Another DDR4 end-of-life delay | Good for legacy pricing, but it holds back bits that would go to DDR5 |
| PC OEM transition pace | Whether "no reason to hold out for DDR4" shows up in actual orders |
| Second-half price path | Morgan Stanley sees DDR4 up as much as 50% Q/Q in Q3 and another 10%+ in Q4 |
Risks to this view
▶ Retail is noisy. Channel inventory, promotions and the exchange rate move it independently. The retail figures here are Samsung-module averages in Korea and vary by brand and by week.
▶ Most end-of-life dates are reporting, not company guidance. SK hynix says nothing is officially set, and Samsung has already pushed its date once.
▶ Forecasts are forecasts. If new capacity lands faster than expected, or set demand rolls over, the path changes.
▶ Nova Lake's launch quarter is disputed across outlets, so no quarter is stated here.
The short version
The same DRAM is more expensive as DDR4 in the chip market and more expensive as DDR5 on the shelf. That is not a contradiction to resolve — it is a question of which market's number you are looking at. And the distance between the two is a decent measure of how far this cycle has stretched.
