Find the Cheapest RAM Per GB in 2026
Looking for the best RAM deals? BuyPerUnit compares 1088+ DDR5 and DDR4 memory kits ranked by price per gigabyte — so you can find the most memory for your money across Amazon, Best Buy, and Newegg.
Right now, the cheapest RAM starts at just $2.281/GB, while the average on this page is $20.328/GB. Whether you're building a gaming PC, upgrading a laptop, or maxing out a workstation, we help you find the best value.
RAM Buying Guide: Get the Best Value
1. More GB = Lower $/GB
A 32GB kit at $60 ($1.88/GB) beats two 16GB kits at $40 each ($2.50/GB) in value. Buying a single larger kit saves money and leaves slots free for future upgrades.
2. DDR5 vs DDR4
DDR5 is faster but costs more per GB. If your CPU supports DDR5, it's worth it for longevity. DDR4 is the better value choice for older platforms — it's mature, plentiful, and dirt cheap.
3. Match Your Platform
AMD Ryzen 7000+ and Intel 12th gen+ use DDR5. Older Intel and AMD use DDR4. SODIMM is for laptops. Always check your motherboard specs before buying.
4. Speed Matters Less Than You Think
DDR5-4800 vs DDR5-6000 is a 5-10% performance difference in most games. Unless you need bleeding-edge performance, stick with the best $/GB and enable XMP/EXPO.
DDR3 vs DDR4 vs DDR5: Which Should You Buy?
| Type | Typical $/GB | Speed | Best For |
|---|---|---|---|
| DDR3 | $0.50–1.50 | 800–2133 MHz | Older Intel/AMD platforms (pre-2015) |
| DDR4 | $2.00–4.00 | 2133–4800 MHz | Intel 10th–11th gen, AMD Ryzen 1000–5000 |
| DDR5 | $3.00–6.00 | 4800–7200 MHz | Intel 12th gen+, AMD Ryzen 7000+ |
