Why Compare Memory by Price Per Gigabyte?
When shopping for RAM, the total price alone can be misleading. A 16GB kit for £50 sounds cheap until you see a 32GB kit for £80 — just £2.50/GB versus £3.13/GB. Comparing memory by price per gigabyte is the fastest way to spot true value.
Larger kits usually offer a lower cost per GB because you are buying more capacity in one purchase. The same logic applies across DDR4 and DDR5, laptop SO-DIMM and desktop DIMM — a higher-capacity kit is often the better deal even when the upfront price is higher.
GigabytePrices tracks hundreds of memory products daily from Amazon UK, automatically calculating the price per gigabyte for every listing. Whether you need DDR5 for a new build, laptop SO-DIMM for an upgrade, or ECC server RAM, you can find the best value in seconds — without doing the maths yourself.
