Is 8GB still enough?

8GB of RAM is enough in 2026 for a Chromebook, a phone and a MacBook used for light work, tight for a Windows 11 laptop, and not enough for a gaming PC. Windows 11 laptops and gaming PCs should have 16GB: Microsoft requires 16GB for a Copilot+ PC, and Epic and Mojang both recommend 16GB for Fortnite and Minecraft: Java Edition.

The extra memory costs less than the matched listings suggest. On Amazon UK at the time of writing (October 2026), the 16GB version of the same budget laptop costs £163.60 to £269.00 more than the 8GB version, but the ASUS Zenbook 14 OLED UM3402YA with 16GB costs £460.62, just 62p more than an 8GB Acer Aspire 3. The full shortlist is in Best laptop under £500 UK 2026.

Is 8GB enough? The verdict by device and use

8GB is enough on four of the nine common devices and uses in Compare Electronic's table, and not enough on the two that matter most for a long-term purchase: a Windows laptop kept for years and a gaming PC. The third column is the amount to buy, not the minimum that boots.

Is 8GB RAM enough for a laptop?

8GB of RAM is enough for a laptop that runs ChromeOS or macOS for browsing, documents and video calls, and too little for a Windows 11 laptop expected to last. The operating system decides the answer. ChromeOS runs most work in a browser and Android apps, and Google sets 8GB as the floor for its Chromebook Plus badge. macOS manages memory tightly on Apple silicon and swaps to a fast SSD when it runs short.

Windows 11 carries more background services, and the apps most home and office workers live in, Microsoft Teams, a Chromium browser and the Office desktop apps, all stay resident in memory. On 8GB, Windows pages to the SSD once a few of them are open, so switching between apps slows down. The cost of that compromise grows with time, because apps and websites get heavier over a laptop's life while soldered memory stays the same.

Is 8GB RAM enough for Windows 11?

8GB runs Windows 11 comfortably for one or two apps at a time, and is tight for a full working day of a browser, Teams and Office. Microsoft's minimum for Windows 11 is 4GB of RAM, 64GB of storage and TPM 2.0, but that is the figure to install the operating system, not to use it. Microsoft's own bar for its newest Windows features is higher: a Copilot+ PC needs a neural processing unit rated at 40 TOPS or more, 16GB of RAM and 256GB of storage.

Compare Electronic's rule for a Windows laptop bought in 2026 is 16GB. The Lenovo IdeaPad Slim 3 15 Gen 10 (Snapdragon X) at £499 is a Copilot+ PC with 16GB of LPDDR5X, and Lenovo rates it at up to 18.5 hours of local video playback. 8GB Windows laptops are the most common trap in budget listings: the Acer Aspire 3 with a Core i7-1255U costs £460.00 with 8GB, and its Core i7 badge does nothing to fix the memory. Older listings show the same pattern; see Best laptop under £300 UK 2026 for the 4GB traps below £300.

How much more does a 16GB laptop cost than 8GB?

On Amazon UK at the time of writing (October 2026), the 16GB version of the same budget laptop costs £163.60 to £269.00 more than the 8GB version, an average of £225.86 across three matched pairs. Each pair below has the same model, processor and 512GB SSD, so memory is the only difference. That works out at about £28 per extra gigabyte.

The last row is the finding that matters. Buyers who switch model rather than upgrade the same one get 16GB for almost nothing: the ASUS Zenbook 14 OLED UM3402YA costs 62p more than the 8GB Acer Aspire 3 and adds a 2.8K OLED screen. Memory prices explain the size of the matched gaps: DRAM contract prices rose sharply through 2026, and TrendForce reported that Dell planned laptop price rises of 15% to 20%, as covered in RAM shortage 2026: why tech is more expensive.

Which 16GB laptop should you buy?

The ASUS Zenbook 14 OLED UM3402YA is the best-value 16GB laptop on Amazon UK at the time of writing (October 2026), at £460.62 with an 8-core AMD Ryzen 7 7730U, a 512GB SSD and a 14-inch 2880x1800 90 Hz OLED screen. It is the top pick in the £500 guide.

Notebookcheck measured about 12 hours of Wi-Fi browsing from the 75 Wh battery, and the laptop weighs 1.39 kg. The Lenovo IdeaPad Slim 3 15 Gen 10 (Snapdragon X) at £499 is the 16GB alternative for battery life, with the caveat that Windows on Arm cannot run games with kernel-level anti-cheat such as Valorant. For macOS, the Apple MacBook Air 13-inch M5 costs £1,189 with 16GB as standard.

Is 8GB RAM enough for a Chromebook?

Yes. 8GB is the right amount for a Chromebook in 2026, and Google sets it as the minimum for the Chromebook Plus badge, alongside 128GB of storage, a 1080p webcam and a Full HD IPS screen. ChromeOS runs Google Docs, Microsoft 365 on the web and Android apps within 8GB without the background load Windows carries.

The Acer Chromebook Plus 514 CB514-5H costs £419 with 8GB, a 10-core Intel Core 5 120U and a 512GB SSD, and the ASUS Chromebook Plus CX34 CX3402CVA costs £289 with 8GB and Google updates until June 2032. Students choosing between the two systems should read Chromebook vs Windows laptop for students.

Is 8GB RAM enough for a MacBook Air?

New MacBook Air models no longer come with 8GB: the Apple MacBook Air 13-inch M5 starts at 16GB of unified memory and costs £1,189 on Amazon UK at the time of writing (October 2026). Apple's 8GB Mac in 2026 is the MacBook Neo, with an A18 Pro chip, which is enough for Safari, Microsoft 365, Zoom and Teams calls and photo edits in the Photos app.

8GB becomes tight on a Mac for 4K video editing, large Xcode projects and local language models. Apple Intelligence runs on any Mac with an M1 chip or later, so 8GB is enough to use it, but Apple's support page reserves up to 14GB of storage for Apple Intelligence on Macs with an M3 or later and at least 12GB of unified memory, against up to 8GB on other Macs. The gap between the two laptops is covered in MacBook Neo vs MacBook Air M5. The Apple MacBook Air 13-inch M5 is the safer buy for anyone keeping a Mac five years.

Is 8GB RAM enough for gaming?

No. 16GB of RAM is the minimum for a gaming PC in 2026, because 8GB meets only the minimum specification of the most-played games. Epic recommends 16GB for Fortnite, Mojang recommends 16GB for Minecraft: Java Edition, and EA recommends 12GB of dual-channel memory for EA Sports FC 27. In Steam's August 2026 hardware survey, 41.20% of PCs had 16GB.

Minecraft: Java Edition shows how integrated graphics raise the bar: since 21 July 2026, Mojang lists 12GB for laptops without a graphics card, because the graphics chip borrows system memory. The full breakdown is in Minecraft PC requirements 2026. The Computek Ryzen 5 5500 RTX 5060 gaming PC costs £797.99 on Amazon UK with 16GB of DDR4, enough for every game in the table.

Is 8GB of VRAM enough in 2026?

8GB of graphics memory (VRAM) is enough for 1080p gaming without ray tracing and falls short with it. Tom's Hardware's GPU hierarchy (June 2026) measured the Radeon RX 9060 XT 16GB at 98.3 fps and the RX 9060 XT 8GB at 93.2 fps across 11 games at 1080p, a 5.5% gap. With ray tracing at 1080p, the 16GB card averaged 45.3 fps against 33.0 fps, a 37% gap from memory alone.

VRAM is separate from system RAM: a PC needs 16GB of RAM whatever its graphics card. The RTX 5060 has 8GB of VRAM and suits 1080p raster gaming; the trade-off between the two cards is covered in RTX 5060 vs RX 9060 XT.

Is 8GB RAM enough for a phone?

Yes. 8GB of RAM is enough for a phone in 2026 and is the standard in mid-range models: the Google Pixel 10a, Samsung Galaxy A57 and Nothing Phone (4a) all ship with 8GB. Apple Intelligence runs on the iPhone 15 Pro and every iPhone 16 or later, according to Apple.

Flagships have moved to 12GB. The Google Pixel 10 and Samsung Galaxy S26 have 12GB, and Apple groups the iPhone 17 Pro, iPhone 17 Pro Max and iPhone Air among devices with at least 12GB of unified memory. The extra memory serves on-device features and camera processing more than everyday apps, so 8GB remains a sound buy for a phone kept three to four years.

Can you add more RAM to an 8GB laptop later?

Usually not. Most budget and thin laptops use LPDDR5 or LPDDR5X memory soldered to the motherboard, and Apple's unified memory is part of the chip package, so the amount bought is the amount kept. Business laptops are the exception: the Lenovo ThinkPad T14 Gen 5 has two DDR5 memory slots and supports up to 64GB.

Renewed business laptops often have 16GB already. The renewed Dell Latitude 5420 costs £254 with 16GB, a 512GB SSD and Windows 11 Pro, cheaper than any new 8GB Windows laptop in the price table. Buyers who need a new laptop should treat 8GB on Windows as a reason to choose another model.

Verdict

8GB of RAM is enough in 2026 for a Chromebook, a phone and a MacBook used for light work. It is tight for a Windows 11 laptop and not enough for a gaming PC, where 16GB is the minimum. The cheapest way to 16GB is a different model, not an upgrade: the ASUS Zenbook 14 OLED UM3402YA has 16GB for £460.62 on Amazon UK at the time of writing (October 2026), 62p more than an 8GB Acer Aspire 3.
