Yes, some games remain playable with 8GB of system RAM, but that does not make 8GB a reliable gaming target. In a January 2026 TechSpot comparison, several titles ran acceptably on a high-end test PC with memory capped at 8GB, while others stuttered, delivered poor frame-time consistency, or reduced texture quality. The results show why average FPS alone can give a misleading picture—and why 16GB is a safer budget baseline, with 32GB a more comfortable target for a general gaming PC.
What the 8GB test can—and cannot—tell you
TechSpot’s Steven Walton tested 8GB, 16GB, 32GB, and 64GB of system memory on January 8, 2026. The test PC used a Ryzen 7 9800X3D, GeForce RTX 5090, and a three-year-old Windows 11 installation, with Chrome (six tabs), Discord, and monitoring tools open. Windows was limited to different amounts of the same 64GB kit, preserving its timings, frequency, and ranks. Games were tested at 4K, typically at maximum quality settings.

This is a controlled comparison of memory capacity on one system, not a guarantee for a different PC, game patch, resolution, or settings profile. The machine’s powerful CPU and graphics card also make it unlike many budget PCs. Still, the results show the range of outcomes: 8GB can be enough to launch and play some games, but it can also compromise smoothness or visual quality. TechSpot’s full 2026 test includes the test conditions and game-by-game results.
Which games were playable with 8GB?
“Playable” does not always mean smooth. In the table, findings refer to TechSpot’s 2026 setup; they are not universal minimum requirements. Frame-time consistency describes how evenly frames arrive: irregular delivery can look and feel like stuttering even when the average frame rate seems reasonable.

- Cost-efficient, high-performance DDR4 upgrade
- Intel XMP-ready
- Ready for AMD Ryzen
- Plug N Play functionality
| Game | What happened at 8GB in the test |
|---|---|
| Arc Raiders | Playable, with only minimal stuttering. TechSpot said 16GB was enough for an optimal experience. |
| Battlefield 6 | Ran reasonably well. The game used around 11GB in the 16GB configuration and up to 14GB when 64GB was available; an 8GB graphics card could add memory pressure at the Extreme preset. |
| Marvel Rivals | Frequent frame stutters. The 16GB, 32GB, and 64GB results were virtually identical in this setup. |
| Borderlands 4 | Average frame rates looked similar, but 1% lows suffered from very inconsistent frame times. |
| Mafia: The Old Country | 8GB was not viable for a smooth experience; the test found around 20GB of system memory was needed. |
| Warhammer 40,000: Space Marine 2 | Apparently reasonable performance figures concealed many high-resolution textures being replaced with low-resolution assets. TechSpot called 16GB the minimum for the tested experience. |
| Black Myth: Wukong | Somewhat playable, but frequent frame-time stuttering was expected. TechSpot strongly recommended 16GB. |
| STALKER 2: Heart of Chornobyl | Poor frame-time consistency at 8GB; the 16GB, 32GB, and 64GB results were broadly similar. |
| Clair Obscur: Expedition 33 | Technically playable, with noticeable stuttering. TechSpot recommended 16GB for an optimal experience. |
| Cyberpunk 2077: Phantom Liberty | Mostly playable in the Ultra test, with occasional frame-pacing issues. The Medium test also showed more stuttering at 8GB. |
| Doom: The Dark Ages | Effectively a non-starter because of constant frame-time issues. |
| Kingdom Come: Deliverance II | Technically playable, but with frequent frame-pacing issues and significantly worse 1% lows. |
| The Outer Worlds 2 | Mostly playable, but with noticeable frame-time issues. |
Why average FPS is not enough
A single average-FPS figure can hide two different problems. First, frames may arrive unevenly: the average can look acceptable while brief pauses or inconsistent pacing make play feel rough. That is why 1% lows and frame-time behavior matter alongside average FPS. Second, a game may appear to run well because it has quietly lowered visual detail. In Space Marine 2, the test found many high-resolution textures had been replaced with lower-resolution assets at 8GB.
When judging a game on a low-memory PC, check for stutter during play and whether texture quality or other assets have changed—not just whether the game starts or what its average FPS reports.

System RAM and graphics-card VRAM are different
System RAM is the computer’s main memory; VRAM is memory on the graphics card. A game may rely on both, and an 8GB graphics card is not equivalent to having 8GB of system RAM. When VRAM is insufficient, some asset data can spill into system memory, increasing pressure on that resource too.

With both that 8GB GPU and only 8GB of system RAM, the tested Marvel Rivals experience was unworkable. In a Spider-Man 2 comparison using 16GB of system RAM, the 16GB RX 9060 XT produced 35% higher average frame rates and 70% better 1% lows than the 8GB version. Those figures belong to TechSpot’s specific tests, not every combination of card and game.

A 2018 TechSpot article also described how limited VRAM, graphics settings, and storage speed can affect memory pressure: if system memory is exhausted too, assets may move to local storage at a severe performance cost. That older article is useful context, not a current compatibility guide. Read the 2018 comparison.

If you play newer games, move between games and other apps, or are troubled by stutters, upgrading is a sensible step. The 2026 comparison found 16GB viable for budget-focused gaming and described 32GB as its general gaming sweet spot. Those are test-based recommendations, not guarantees that every game needs the same capacity. Walton’s conclusion was: “32GB is the sweet spot for gamers.”

Before buying memory, check what your PC supports: memory generation, form factor, maximum capacity, and available slots. A laptop may use a different form factor from a desktop, and some systems may not allow memory upgrades. The benchmark does not establish compatibility for your particular computer.

- Start with the games and patches you actually use. The test ranged from minimal stuttering in Arc Raiders to constant frame-time problems in Doom: The Dark Ages.
- Look beyond average FPS. Check 1% lows, frame-time consistency, and whether stutters appear during play.
- Inspect visual quality. A game that runs may still substitute lower-resolution textures or other assets.
- Account for the whole PC. GPU VRAM, background apps, resolution, and graphics settings all affect memory pressure.
- Verify upgrade compatibility. Confirm the memory type, form factor, slot availability, and supported capacity before choosing a kit.
For historical context, TechSpot’s 2018 comparison found that the effects of 8GB varied by game, including weaker frame-time performance in some Battlefield V and Shadow of the Tomb Raider tests. Its then-current 16GB “sweet spot” conclusion dates to 2018; the newer test gives a better basis for present-day guidance. See the 2018 test details.
