Thinking about playing Subnautica on PC and wondering what hardware you actually need? Subnautica is an underwater survival game that launched in January 2018, and the good news is that it is genuinely light on hardware: the official minimum asks for a modest dual-core Haswell-era processor, 4 GB of RAM and integrated graphics such as Intel HD 4600, while the official recommended spec tops out at a GTX 550 Ti-class card with 8 GB of RAM. In other words, most desktops and laptops built in the last several years will run it without any upgrades at all. This guide breaks down the official PC requirements for Subnautica, the best GPU for each resolution, and complete build recommendations to hit your target frame rate.
How Demanding Is Subnautica?
Subnautica is light on PC hardware. It is an older title built on a modest engine, and its official requirements reflect that: the minimum graphics requirement is Intel HD 4600-class integrated graphics, and the recommended card is a 2012-era GeForce GTX 550 Ti with 2 GB of VRAM. The CPU side is similarly gentle, with a Haswell quad-core at 3.2 GHz listed as the recommended part, and the game needs only 20 GB of drive space. In practical terms that means almost any modern processor and a basic discrete GPU will handle 1080p, while 1440p and 4K are realistic targets for mid-range cards rather than something that demands a flagship. The figures below are based on the official specs; always check the game’s official store page for the exact published requirements.

Best GPU for Subnautica by Resolution
1080p
1080p is easy territory for this game. The official minimum is integrated Intel HD 4600-class graphics, so even older budget cards such as a GTX 1050 Ti or RX 570 will run Subnautica at 1080p, and current entry-level options — an RTX 5060, an RX 9060 XT or an Intel Arc B580 — leave plenty of headroom. The AMD Radeon RX 7600 (or a comparable card) is a comfortable pick that handles high settings without breaking a sweat.
1440p
1440p is well within reach of mid-range hardware. A card like the RTX 5060 Ti, the RX 9060 XT or the previous-generation NVIDIA GeForce RTX 4070 SUPER is far more than Subnautica needs, giving you high-refresh 1440p at high or ultra settings with room to spare. This is the resolution most PC gamers target, and any current mid-range card will treat this 2018 title as an easy workload.
4K
Subnautica is not a demanding game at 4K. A modern upper mid-range card — an RTX 5070, an RX 9070, or the NVIDIA GeForce RTX 4070 Ti SUPER — has more than enough muscle for it, and you generally will not need upscaling or a flagship GPU to enjoy the game at this resolution. If you already own a card in this class, Subnautica is a title you can simply set to your preferred quality level and forget about.
CPU, RAM and Storage for Subnautica
Subnautica’s CPU requirements are modest: the official minimum is a Haswell-era dual-core with four threads at 2.5 GHz, and the recommended part is a 3.2 GHz Haswell quad-core. Any modern desktop processor clears that bar comfortably, so you do not need a high-end chip for this game. If you are building a general-purpose gaming PC anyway, the AMD Ryzen 5 7600 is excellent value, while the AMD Ryzen 7 7800X3D is one of the fastest mainstream gaming CPUs available. Intel fans can opt for the Intel Core i5-14600K. For memory, the official recommended figure is 8 GB; 16 GB is a comfortable modern baseline, and a 32 GB DDR5 kit such as the Corsair Vengeance DDR5 32GB leaves generous room for everything else you run alongside the game. Storage is a non-issue at roughly 20 GB, so any drive works; installing Subnautica on an SSD like the Samsung 990 Pro 2TB NVMe SSD shortens load times, but a hard drive is perfectly workable.
Recommended PC Builds for Subnautica
Subnautica runs comfortably on far less than the builds below, so treat these as sensible modern targets if you also play newer, heavier games.
1080p budget build: AMD Radeon RX 7600 + AMD Ryzen 5 7600 + 16 GB DDR5 — far more than Subnautica needs at 1080p, and a solid all-round budget gaming setup.
1440p sweet-spot build: NVIDIA GeForce RTX 4070 SUPER + AMD Ryzen 7 7800X3D + 32 GB DDR5 + 2TB NVMe SSD — overkill for Subnautica, but a great foundation for other titles.
4K high-end build: NVIDIA GeForce RTX 4070 Ti SUPER + AMD Ryzen 7 7800X3D + 32 GB DDR5 + fast NVMe SSD — comfortable 4K in this game, with plenty of headroom elsewhere.
Is It Worth Upgrading Your PC for Subnautica?
If your current PC already runs Subnautica, it is rarely worth upgrading just for this game: it launched in 2018 with a GTX 550 Ti-class recommendation and still runs happily on old hardware. If you are upgrading anyway, the graphics card usually delivers the biggest jump in gaming performance, so put your budget there first. The CPU bar is low, so a processor upgrade only makes sense if you are on a very old platform and also want more performance in newer games. Going up to 8–16 GB of RAM and moving the game to an SSD are inexpensive quality-of-life improvements, but neither is required. Rather than replacing everything at once, target the weakest link in your build for the best value.
Can You Play Subnautica on a Laptop or Handheld?
Subnautica is an excellent fit for laptops and handhelds. Because the official minimum is integrated Intel HD 4600-class graphics, almost any gaming laptop from the last several years — and many thin-and-light machines with modern integrated graphics — can run it. On handhelds like the Steam Deck and ROG Ally, this light 2018 title runs comfortably at reasonable settings, making it a great portable pick. If portability matters, prioritise a device with decent battery life and pair it with a fast microSD or SSD for storage; the game takes up only about 20 GB, so it fits easily.
How to Boost FPS in Subnautica
If frame rates are lower than you would like, start by lowering the overall quality preset, then trim the most expensive effects such as shadows and post-processing before dropping the resolution further. Keep your GPU drivers up to date, close background apps, and make sure the game has enough free space on its drive. On older hardware, driver-level upscaling or a lower render resolution can help, though most systems running Subnautica will not need either. Lowering settings to hit a stable frame rate almost always feels better than chasing maxed-out visuals with stutter.
Frequently Asked Questions
Can my PC run Subnautica?
Almost certainly. The official minimum is a Haswell-era dual-core with four threads at 2.5 GHz, 4 GB of RAM and graphics around Intel HD 4600 level, while the recommended spec is a 3.2 GHz quad-core, 8 GB of RAM and a GTX 550 Ti-class card with 2 GB of VRAM. Any PC with a modern quad-core processor, 8 GB of RAM and a basic discrete or modern integrated GPU will run Subnautica comfortably.
Is Subnautica demanding on PC?
No. Subnautica is a light, older title — its recommended GPU is a 2012-era GTX 550 Ti, and its minimum graphics requirement is integrated Intel HD 4600-class hardware. Budget and mid-range systems handle it easily at 1080p, 1440p and even 4K.
What GPU do I need for Subnautica at 1440p 60fps?
Very little by modern standards. Any current mid-range card — an RTX 5060, an RX 9060 XT or similar — handles 1440p in Subnautica with room to spare, and even older cards below that class will do the job. A NVIDIA GeForce RTX 4070 SUPER-class graphics card is far more than enough for high-settings 1440p, and gives you headroom for much heavier games too.
How much RAM does Subnautica need?
The official recommended amount is 8 GB, with 4 GB listed as the minimum. 16 GB is a sensible target for a modern gaming PC since it covers Subnautica and everything else you are likely to run, but the game itself is comfortable with 8 GB.
Do I need an SSD for Subnautica?
No — an SSD is optional. The game needs only about 20 GB of space and will run from a hard drive. An NVMe drive like the Samsung 990 Pro will shorten load times, but it is not required to play.
