DDR4 remains the most affordable option per gigabyte, making it a great choice for budget builds and upgrades to existing systems. DDR5 costs more per GB but offers higher bandwidth and better power efficiency, making it the preferred choice for new builds on Intel 12th Gen+ or AMD Ryzen 7000+ platforms.

RAM Price Per GB by Capacity

CapacityCheapest /GBAverage /GB
8GB£7.50£11.24
16GB£7.90£15.75
32GB£6.22£16.67
64GB£7.75£12.14
128GB£14.06£14.88

As a general rule, higher-capacity kits offer a lower price per gigabyte. A 32GB kit typically gives you a better price per GB than a 16GB kit. For the best value, consider buying the largest capacity your budget and motherboard support.

Desktop DIMM memory is typically the cheapest per gigabyte, followed by laptop SO-DIMM modules. Server ECC/registered memory commands a premium due to error-correcting capabilities and higher reliability ratings required for 24/7 operation.

What Affects the Price of RAM?

Several factors influence how much you'll pay per gigabyte of RAM:

  • DDR Generation – DDR5 costs more than DDR4 due to newer technology, though the gap is closing as DDR5 matures.
  • Speed (MHz) – Higher-speed modules (e.g., DDR5-6400 vs DDR5-4800) cost more per GB. For most users, mid-range speeds offer the best value.
  • Capacity – Larger kits (32GB+) generally offer lower prices per gigabyte than smaller kits.
  • Form Factor – Laptop SO-DIMM modules typically cost slightly more than desktop DIMMs.
  • ECC / Server Grade – Error-correcting memory for servers costs more due to additional components and testing.
  • Brand – Premium brands like Corsair and G.Skill may charge more than budget options, though performance can vary.
  • Timing / Sales – RAM prices fluctuate regularly. Black Friday, Prime Day, and other sales events can offer significant discounts.

Frequently Asked Questions

How much does 1GB of RAM cost in 2026?

In 2026, the price per gigabyte of RAM varies by type. DDR4 memory typically costs £1.50-5.00 per GB, while DDR5 ranges from £2.00-8.00 per GB. Server ECC memory tends to be more expensive. The cheapest RAM per GB is usually found in higher-capacity kits (32GB+) as they offer better value per gigabyte.

Is DDR4 or DDR5 RAM cheaper per GB?

DDR4 RAM is generally cheaper per gigabyte than DDR5 in 2026. DDR4 has been on the market longer and has more competition, driving prices down. However, DDR5 prices have fallen significantly and the gap is narrowing. For new builds on modern platforms, DDR5 offers better long-term value despite the slightly higher cost per GB.

Why does laptop RAM cost more per GB than desktop RAM?

Laptop memory (SO-DIMM) typically costs slightly more per gigabyte than desktop memory (DIMM) because SO-DIMM modules are physically smaller and have higher manufacturing density requirements. However, the price difference has narrowed in recent years and some laptop memory kits are competitively priced.

How much RAM do I need for my computer?

For basic computing and web browsing, 8GB is sufficient. For gaming and general productivity, 16GB is recommended. Content creators, video editors, and heavy multitaskers should consider 32GB. Professional workstations and servers may need 64GB or more. Buying more capacity usually gives you a better price per GB.

Does buying more RAM give better value per GB?

Yes, larger capacity kits generally offer a lower price per gigabyte. For example, a 32GB kit (2x16GB) typically costs less per GB than two separate 8GB modules totalling 16GB. This economy of scale means buying the largest kit your budget allows is usually the best value.
