16GB or 32GB for gaming?

Yes. 16GB of RAM is enough for gaming in 2026: nine of the 11 major PC games below recommend 16GB or less, and TechSpot found 16GB delivered the same performance as 32GB in 12 of 13 games. 32GB is worth buying when a new gaming PC costs about £60 more with it, and for any PC with an 8GB graphics card, where the extra memory cuts stutter.

Compare Electronic's budget picks follow the same line. The Computek Ryzen 5 5500 RTX 5060 tower at the top of Best budget gaming PC UK 2026 ships with 16GB for £797.99 on Amazon UK at the time of writing (October 2026), and the ZeroLag AZ with the same processor, graphics card and 32GB costs £859.00. The table gives the verdict by situation.

How much RAM do 2026 PC games need?

Most major PC games recommend 16GB of RAM in 2026, and five of the 11 in Compare Electronic's table list 16GB as the minimum. The figures are each publisher's official minimum and recommended specifications, as listed on Steam or the publisher's own site in October 2026.

Two games recommend 32GB. 2K pairs 32GB with an RTX 3080 in its Borderlands 4 recommendation, and Xbox Game Studios lists 32GB for Microsoft Flight Simulator 2024. Both still run on 16GB at their minimum specification, and TechSpot found Borderlands 4 ran roughly on par with 32GB on a 16GB system, despite using up to 18GB when more was available. At the other end, 8GB no longer meets the minimum for Battlefield 6, Marvel Rivals or Monster Hunter Wilds; the full 8GB picture is in Is 8GB RAM enough in 2026?

Does 32GB of RAM give more fps than 16GB?

Not in most games: 32GB raises performance only when a game or the graphics card runs out of memory. TechSpot's January 2026 comparison, run on a Ryzen 7 9800X3D and an RTX 5090 at 4K with Chrome and Discord open in the background, found 16GB matched 32GB on average frame rate and 1% lows in 12 of 13 games. Battlefield 6 used about 11GB on the 16GB setup. The exception was Mafia: The Old Country, which needed about 20GB for smooth frame times.

The graphics card changes the answer. With an 8GB Radeon RX 9060 XT in Spider-Man 2, textures that overflow the card's memory move into system RAM, and TechSpot measured 1% lows more than 60% higher with 32GB than with 16GB. That matters for budget buyers, because the RTX 5060 in most UK gaming PCs under £1,000 also has 8GB of VRAM. TechSpot's verdict was that "32GB is the sweet spot for gamers", while "most games still run perfectly well with 16GB".

Players are moving the same way. In Valve's Steam Hardware and Software Survey for September 2026, 43.28% of Windows PCs had 32GB, up 4.81 points in a month, overtaking 16GB at 37.60%. The trade-off between 8GB and 16GB graphics cards is covered in RTX 5060 vs RX 9060 XT.

How much more does a 32GB gaming PC cost?

On Amazon UK at the time of writing (October 2026), 32GB adds £60.00 to £83.00 to a gaming PC with the same processor and graphics card, a premium of 5.1% to 10.4%. That is a quarter to a third of the £239.99 a 32GB DDR4 kit costs as a later upgrade.

The ADMI row is the warning. ADMI lists its 32GB Ryzen 7 5700X RTX 5060 build for £80.00 less than its 16GB build in a different case, so case and builder margins can outweigh the memory. Buyers should compare whole listings, not the RAM line alone.

Upgrading later costs far more, because DDR5 prices roughly tripled in a few months. Counterpoint Research data showed a 32GB DDR5 module rising from around $94 in late 2025 to $282 in the first quarter of 2026, as memory makers moved production to data-centre memory; the background is in RAM shortage 2026: why tech is more expensive.

DDR5 PCs pay the most. The CyberPowerPC x MSI PBM runs 16GB of DDR5 on AMD's AM5 platform, so its 32GB upgrade, the £390.00 Crucial Pro kit, costs 39.4% of the £989 PC. The DDR4 Computek tower needs the £239.99 Corsair kit, 30.1% of its price.

Which gaming PC should you buy: 16GB or 32GB?

The ZeroLag AZ Gaming PC with a Ryzen 5 5500, an RTX 5060 and 32GB of DDR4 is the best-value 32GB gaming PC on Amazon UK at the time of writing (October 2026), at £859.00. It costs £61.01 more than the 16GB Computek tower with the same processor and graphics card, and swaps Computek's 256GB SSD and 1TB drive for a 1TB NVMe SSD.

The 32GB suits the RTX 5060's 8GB of VRAM, the combination TechSpot found gains most from extra system memory. The compromise is the power supply: ZeroLag lists an MSI 500 W 80 Plus unit, below the 550 W Nvidia recommends for an RTX 5060 system, so a graphics card upgrade needs a new PSU. Windows 11 Pro, Wi-Fi and Bluetooth come installed.

Verdict

16GB of RAM is enough for gaming in 2026, and nine of 11 major games recommend no more. 32GB is the better buy in a new PC when it costs about £60 extra, as it does in the £859.00 ZeroLag AZ RTX 5060, and especially with an 8GB graphics card; upgrading later costs £239.99 to £512.18.
