DDR4 vs DDR5 Price in 2026: Which Is Actually Cheaper?
For years DDR4 was the obvious budget choice. In 2026 that has flipped. With memory makers winding down DDR4 production it has become scarce and frequently costs more per GB than DDR5, while DDR5 itself is elevated by the AI-driven DRAM shortage. In practice the answer is almost always decided by your motherboard, not the price tag. Here is how the two compare today.
How this guide stays current
RamRadar re-ranks these picks using live pricing and current fit signals instead of leaving a static affiliate list untouched for months.
Market-aware ranking
We favor kits trading well versus their all-time low so this page points to buyable options, not stale listicles.
Fit before hype
Capacity, platform fit, and real-world value matter more than headline specs that rarely change your outcome.
Trust-aware offers
We bias toward known brands and cleaner retailer signals so weak or misleading listings do not dominate the recommendations.
Quick recommendation
- •For a new build, buy DDR5 — every current AMD AM5 and Intel LGA1851 platform requires it.
- •Buy DDR4 only to upgrade an existing AM4 / LGA1200 / DDR4-era board.
- •DDR4 is no longer reliably cheaper per GB; treat it as a legacy purchase, not a value play.

FAQ
Is DDR4 cheaper than DDR5 in 2026?
Often no. DDR4 is end-of-life and increasingly scarce, so its per-GB price has risen and now frequently matches or exceeds DDR5. The old "DDR4 equals budget" rule no longer holds.
Can I put DDR5 in a DDR4 motherboard?
No. The slots are physically keyed differently and the platforms are incompatible. Your motherboard and CPU socket decide which one you can use.
Should I upgrade my DDR4 system or move to DDR5?
If your current board takes DDR4 and you just need more memory, buying DDR4 now (while it is still available) is fine. If you are replacing the CPU and motherboard anyway, move to a DDR5 platform.
