Choosing the right RAM is one of the most common questions when building or upgrading a computer. In 2025, DDR5 is the new standard, but DDR4 is still common and cheaper. So which one should you choose – DDR4 or DDR5? Here we explain the differences.

What are DDR4 and DDR5?

• DDR4 – Introduced in 2014. Most common in computers built up to 2021–2022. Cheaper, but lower bandwidth.

• DDR5 – Launched in 2020. Current standard in new gaming computers. Higher speeds and more future-proof.

Performance Differences

• Speed:

  • DDR4 → Typically 2400–3600MHz.

  • DDR5 → 4800–8000MHz (6000MHz is most common in 2025).

• Latency:

  • DDR4 often has lower CL values (e.g., CL16–CL18), providing fast response times.

  • DDR5 has higher CL (CL30–CL40), but its higher frequency still delivers better overall performance.

• Capacity:

  • DDR4 → Max 16GB per module (usually).

  • DDR5 → Common with 16GB or 32GB per module. Perfect for 32–64GB RAM in gaming and work computers.

Price and Availability in 2025

• DDR4 → Cheaper, especially if you already have a motherboard that supports it.

• DDR5 → Has become significantly cheaper compared to 2021–2022. Today, the price difference is often marginal, especially for 32GB kits.

Who is DDR4 suitable for?

• You already have a computer with a DDR4-compatible motherboard.

• You want to upgrade on a budget and not replace the entire platform.

• You play simpler titles or use the computer for everyday tasks.

Who is DDR5 suitable for?

• You are building a brand new computer in 2025.

• You want the highest possible performance in new games.

• You are thinking long-term and want to future-proof your computer.

FAQ

Is DDR5 always better than DDR4?
Yes, but the difference can vary depending on the game and application. In modern titles, you often get 5–15% better performance with DDR5.

Can I use DDR4 in a DDR5 motherboard?
No. Motherboards support either DDR4 or DDR5, never both.

Is it worth upgrading from DDR4 to DDR5?
If you are planning to change your CPU/motherboard anyway → Yes. If you only want to upgrade RAM and currently have DDR4 → No, in that case, it's more cost-effective to buy more DDR4.
