Subnautica benchmark on RX 580 8GB: FPS by resolution and quality
Pick yours and we recalculate the whole table above with it.
Subnautica FPS with a RX 580 8GB and a Intel Core i5-13400
| Quality | 1080p (Full HD) | 1440p (2K) | 4K (Ultra HD) |
|---|---|---|---|
| Ultra | 58FPS min 50Acceptable | 37FPS min 33Acceptable | 14FPS min 13Unplayable |
| High | 76FPS min 66Good | 48FPS min 42Acceptable | 19FPS min 17Poor |
| Medium | 99FPS min 86Good | 63FPS min 56Good | 24FPS min 21Poor |
| Low | 128FPS min 111Excellent | 82FPS min 72Good | 32FPS min 29Acceptable |
| Bottleneck (estimated) | balanced | GPU 40% | GPU 77% |
The percentage estimates how much of the stronger component's capability goes unused because of the other one.
This one does matter: from the Intel Core i5-10400F downwards the processor becomes the brake on the RX 580 8GB. There is 18% between the slowest and fastest CPU in the table. One caveat: this is at 1080p, where the CPU weighs most. At 1440p and 4K the graphics card takes over and the processor stops mattering.
FSR performance: FPS with AI upscaling
Upscaling renders Subnautica at a lower internal resolution and reconstructs the image, so you trade a little sharpness for extra frames. These are the estimated figures for the RX 580 8GB with FSR enabled, starting from its native Ultra FPS.
| Resolution | Native | FSR Quality | FSR Performance |
|---|---|---|---|
| 1080p | 58 | 73 | 84 |
| 1440p | 37 | 50 | 61 |
| 4K | 14 | 20 | 26 |
About ray tracing: every figure on this page is with ray tracing off. The RX 580 8GB has no dedicated hardware for it, so it is an option best left disabled.
Estimated figures. The real gain varies by game and by the version of the technology.
Is the CPU or the graphics card holding you back?
These FPS assume a mid-range CPU that isn't a bottleneck — roughly a Intel Core i5-13400 — and 16 GB of RAM.
The RX 580 8GB and that processor are well matched in Subnautica: neither clearly holds the other back, so the table figures are a fair reflection of the pair. At 4K it flips: there the graphics card becomes the limit.
Is the RX 580 8GB Enough for Subnautica?
The RX 580 8GB delivers 58 FPS at 1080p Ultra in Subnautica. Performance is acceptable but not ideal. Consider lowering the resolution or quality.
At 1440p it gets 37 FPS and at 4K 14 FPS at Ultra quality.
This GPU does not reach 60 FPS at 1080p Ultra
