DDR4 RAM is still cheaper per gigabyte than DDR5 in 2026, typically by 20 to 40 percent depending on speed, capacity, and kit configuration. A 32GB DDR4 kit runs $1.56 to $2.19 per gigabyte. A 32GB DDR5 kit runs $2.19 to $3.13 per gigabyte. The gap has compressed significantly from the early DDR5 launch days — DDR5 launched at nearly $10/GB in 2021 — but it has not closed.
Whether that gap is relevant depends entirely on your platform. Modern Intel and AMD systems have made the DDR generation choice for you in most cases. Here is the full picture: what things actually cost, what drives the price difference, and how to find the cheapest option for your specific situation.

DDR4 vs DDR5 Price Per GB: The Current Reality
The numbers as of early 2026, across major retailers:
| Configuration | DDR4 Price Range | DDR4 Per GB | DDR5 Price Range | DDR5 Per GB |
|---|---|---|---|---|
| 16GB (2x8GB) | $30–$45 | $1.88–$2.81/GB | $40–$55 | $2.50–$3.44/GB |
| 32GB (2x16GB) | $50–$70 | $1.56–$2.19/GB | $70–$100 | $2.19–$3.13/GB |
| 64GB (2x32GB) | $100–$140 | $1.56–$2.19/GB | $120–$175 | $1.88–$2.73/GB |
| 96GB (2x48GB) | N/A | N/A | $160–$220 | $1.67–$2.29/GB |
A few things to note in this table:
- DDR4 and DDR5 are converging most visibly at the 64GB tier. DDR5 64GB kits have come down far enough that the premium over DDR4 is sometimes under $30 — a non-issue if you're building a DDR5 platform anyway.
- DDR5 gains a unique capacity advantage at 96GB via 2x48GB kits, a configuration that does not exist in DDR4. For users who need exactly 96GB, DDR5 is your only option.
- The 32GB tier is where most buyers land, and the $20 to $30 DDR5 premium at that capacity is real but not prohibitive.
These prices shift. RAM is a commodity and pricing responds to global DRAM production cycles, smartphone demand, and server procurement. The current market has been relatively stable in early 2026 after significant price pressure in 2024 and 2025.
Why DDR4 Is Still Cheaper
DRAM economics are counterintuitive. You might expect a mature, older technology to be cheaper to produce — and DDR4 is indeed at the mature end of its production curve. But the price difference is not purely about manufacturing cost.
DDR4 supply is massive. DDR4 production lines have been running at scale for years. Manufacturers are not ramping capacity for DDR4; they're running existing capacity to exhaustion before retiring those lines to DDR5 production. This means a large supply of DDR4 modules hitting the market at prices that reflect clearing existing inventory more than optimizing for margin.
DDR5 is the active investment platform. Samsung, SK Hynix, and Micron are building new DDR5 production lines, ramping yields, and still optimizing for cost efficiency. The product is newer, the lines are newer, and the per-unit cost has not fully matured. It will continue to fall.
Speed binning costs money. High-frequency DDR5 (DDR5-6000, DDR5-6400) requires selecting chips that meet tighter tolerances — a process called binning that inherently wastes some production capacity. This is why DDR5-6000 XMP kits cost more than DDR5-4800 base-spec kits, and why frequency alone substantially affects price per GB.
The Cheapest RAM by Use Case
Gaming on a DDR4 Platform (AM4 or Older Intel)
If you are on AMD AM4 (Ryzen 5000 or older) or Intel 12th/13th gen with a DDR4 motherboard, your memory type is fixed. The cheapest upgrade path:
- 16GB to 32GB upgrade: Add a second 2x8GB kit matching your existing RAM, or replace with a 2x16GB kit. A 32GB DDR4-3200 CL16 kit from G.Skill, Corsair, or Kingston runs $50 to $65. That is $1.56 to $2.03/GB — hard to beat.
- Already at 32GB: Adding more DDR4 is cheap. 64GB DDR4 kits are available for $100 to $130. Unless you have a specific workload demanding more, 32GB is fine for gaming.
- Target speed: DDR4-3200 is the sweet spot. DDR4-3600 is slightly faster for Ryzen (better Infinity Fabric sync) but costs $5 to $15 more per kit. DDR4-3200 is fine for Intel platforms. Avoid DDR4-2133 or DDR4-2400 — these are laptop salvage speeds that sometimes appear in desktop listings at deceptively low prices.
Building New on DDR5 (Intel 14th Gen or AMD AM5)
If you're buying a new platform in 2026, you are almost certainly on DDR5. The platform defines the memory type — this is not optional. The cheapest path to value:
- 32GB baseline: A 2x16GB DDR5-6000 CL36 kit costs $70 to $90 from Corsair, G.Skill, or Kingston. At $2.19 to $2.81/GB, this is the entry-level value tier for DDR5.
- AMD AM5 target speed: DDR5-6000 with EXPO support. This is AMD's tuned sweet spot. Going to DDR5-6400 or higher delivers minimal additional performance at a real cost premium.
- Intel 14th Gen target speed: DDR5-5600 to DDR5-6400 with XMP support. Intel's memory controller is slightly less frequency-sensitive than AMD's. DDR5-5600 CL36 is a solid value buy.
- Avoid DDR5-7200 and above: These binned kits target benchmarkers, not everyday builders. They cost $20 to $60 more per kit for performance gains that are unmeasurable in real workloads. The extra money is genuinely wasted for gaming and content creation.
Content Creation / Local AI Workloads
Memory bandwidth matters more here. For video editing, 3D rendering, or running local LLMs:
- Minimum 64GB. 32GB runs tight with modern video editors and AI models. 64GB gives you real headroom.
- DDR5 is worth it. The bandwidth advantages of DDR5 show up in exactly these workloads. If you're spending money on a workstation, DDR5-6000 64GB is the baseline.
- Value pick: G.Skill Flare X5 DDR5-6000 64GB kits frequently hit the best $/GB in the DDR5 64GB category. Watch for sales — this category sees aggressive promotional pricing.
Mixing RAM kits is technically possible but practically risky. Two kits from different manufacturers, different speeds, or different latency ratings can cause instability even if they are individually compatible with your platform. For best results, buy all your RAM at once as a matched kit. If you need to expand later, try to find the identical model you already own.
Where to Find the Cheapest RAM Right Now
RAM pricing is volatile and the cheapest retailer changes regularly. A few strategies:
Check Amazon and Newegg simultaneously. These two split RAM deals most often. Best Buy carries a narrower RAM catalog and rarely wins on price for memory.
Watch for manufacturer rebates. G.Skill, Corsair, and Kingston all run periodic rebate offers that can cut $10 to $20 off kit prices, particularly on slower-moving high-capacity kits. These are not advertised loudly — check the product page or the manufacturer's rebate portal.
Buy on sale events, not urgency. RAM does not go out of stock the way GPU or CPU deals do. A 32GB DDR4 kit will still be available in three weeks. The smart move is setting a target price (e.g., "I'll buy when 32GB DDR5-6000 CL36 drops under $75") and acting when it hits.
BuyPerUnit tracks RAM prices from Amazon, Best Buy, and Newegg daily and ranks every kit by price per GB. When a kit drops to its floor price across any of the three retailers, it surfaces at the top of the ranking. That is the fastest way to catch a RAM deal without manually watching three sites.

Is DDR4 or DDR5 cheaper in 2026?
DDR4 is still cheaper per GB. A 32GB DDR4 kit runs $1.56 to $2.19/GB. A 32GB DDR5 kit runs $2.19 to $3.13/GB. The gap has closed significantly from DDR5's launch — when it cost nearly $10/GB — but DDR4 still wins on pure price per gigabyte.
What is the cheapest DDR5 RAM?
Budget-tier DDR5 32GB kits from Kingston Fury Beast, Crucial, and G.Skill Ripjaws S5 at DDR5-4800 or DDR5-5600 CL46 regularly hit the lowest per-GB cost in the DDR5 category — sometimes under $2.30/GB. These run at base or near-base spec speeds but deliver the DDR5 bandwidth advantages at the lowest price. BuyPerUnit shows live rankings of the cheapest DDR5 kits by price per GB.
How much RAM do I need in 2026?
32GB is the practical baseline for most desktop users. 16GB works but runs tight with modern browsers, background processes, and any creative software. 64GB is worth it for video editing, 3D rendering, and local AI workloads. 128GB is for serious workstations and server applications.
What speed DDR5 should I buy?
For AMD AM5: DDR5-6000 CL36 with EXPO support. For Intel 14th Gen: DDR5-5600 to DDR5-6400 with XMP support. Avoid DDR5-7200 and above unless you benchmark for competition — the real-world gains over DDR5-6000 are unmeasurable in games and most applications, and the price premium is substantial.
