How much RAM do you need for gaming in 2026?

In 2026, 16GB of RAM is enough to play almost anything, and 32GB is the comfortable choice if you do other things at the same time. Memory is not what makes frames per second: the graphics card is. RAM is there so you don't run out, and beyond that point each extra gigabyte brings you almost nothing.

This guide tells you which capacity to pick for how you play, how many sticks to buy, and what the rise in DDR5 prices changes. The measurements quoted come from press tests, not from our performance table: our FPS figures don't depend on RAM.

How much RAM do you need for gaming in 2026?

Here is the answer by profile.

• 8GB: the floor has been passed. Windows, your browser and the game launcher already use part of it. Keep it for an old PC that only runs light games.
• 16GB: the reasonable minimum for a new PC. Press tests show average FPS very close to 32GB in most recent games.
• 32GB: the comfortable choice. You can keep Discord, a loaded browser and a capture tool open without a second thought, and you have headroom for the years ahead.
• 64GB: pointless for gaming. It only makes sense for heavy video editing, 3D work or some very heavily modded simulations.

The second row is the one that matters. With 16GB, a recent game can get close to the limit: TechSpot tested more than 30 games, and about half a dozen approach or exceed 16GB, with Hogwarts Legacy the hungriest, while the great majority run fine on 16GB, often with little headroom. When RAM fills up, Windows writes to the SSD and you feel a hitch.

16GB or 32GB: what difference in games?

On the average frames per second, almost none. In TechSpot's tests, most games show very similar averages between 16GB and 32GB. Only a handful of very demanding titles, such as Hogwarts Legacy, clearly benefit.

The difference appears elsewhere: in the 1% lows, the slowest frames of a session. These are the ones you perceive as a micro-stutter. With more memory, these dips are rarer and shallower. A game can therefore show the same average on 16GB and 32GB and still feel nicer on 32GB.

Which games really benefit from 32GB?

Most online games and big single-player titles are comfortable with 16GB. Three families of games justify 32GB.

• Simulators. Microsoft Flight Simulator 2024 lists 16GB as the minimum, 32GB as recommended and 64GB as the ideal configuration. Racing or management simulations with a lot of content follow the same logic.
• Modded games. A game with hundreds of mods, such as Skyrim or a Minecraft world loaded with packs, fills memory quickly.
• Dense open worlds, like Cyberpunk 2077, which stay playable on 16GB but take advantage of the headroom when you have other programs open.

If you mostly play competitive games like Valorant or Counter-Strike 2, 16GB is plenty: put the difference towards the graphics card instead.

On a tight budget, 16GB in two sticks and the difference invested in the graphics card give a better experience than 32GB with a weaker card.

How many sticks: one or two?

Take two identical sticks. They run in dual channel, meaning the processor reads the memory through two lanes in parallel. A single stick leaves only one lane open.

Press tests show that the gap depends a lot on the game: a few per cent on the average in some titles, clearly more on the 1% lows in others. DDR5 limits the damage compared with the older DDR4, because each stick already holds two sub-channels, but dual channel is still the right reflex.

For 32GB, that means 2 × 16GB. For 16GB, 2 × 8GB. Two sticks also leave you the option of adding two more later, if your motherboard has four slots. Fit them in the slots shown in your motherboard manual, usually every other one.

Which RAM speed should you choose?

On a recent AMD platform (AM5), DDR5-6000 with CL30 latency is the usual starting point. At that frequency, the memory and the processor work in good harmony. Faster kits cost more for a small gain, and the graphics card remains the dominant factor for FPS.

Two practical tips:

• Enable the XMP or EXPO profile in the BIOS. Without it, your RAM runs at a base speed well below the one printed on the box.
• Check compatibility. A DDR5 motherboard does not accept DDR4, and the other way round. The two cannot be mixed.

Why is RAM so expensive in 2026?

The price of DDR5 has risen sharply since late 2025. In October 2026, expect roughly £280 to £450 for a 32GB DDR5-6000 kit at UK retailers, depending on the brand, and roughly £210 to £290 for a 16GB (2 × 8GB) kit. These ranges are indicative: prices move quickly and vary from shop to shop, so check the price on the day you buy. The commonly cited cause is manufacturers shifting production towards memory for artificial intelligence, at the expense of consumer memory.

What it changes for you:

• Choosing 16 or 32GB has a real cost. The gap between the two, anywhere from about £50 to £200 depending on the kits, is a large part of the price of an entry-level graphics card. Ask yourself how you actually use your PC instead of taking 32GB by reflex.
• Compare prices on the day you buy. Price trackers contradict one another, and prices move fast. Don't rely on any fixed figure, including ours.
• Don't go for DDR4 to save money without checking the whole platform: it needs another motherboard and another processor, and it closes the door on future upgrades.

If you're unsure, our configurator takes your games, your budget and today's prices into account to tell you whether the extra cost of 32GB is worth it, or whether that money is better spent elsewhere.
