How to Fish on Radeon HD 7870

Meets minimumEstimate · low confidence, ±30%

Yes, at lower settings. The Radeon HD 7870 meets How to Fish's minimum spec but not the recommended one. We estimate ~43 fps at 1080p high (range 30–56, low confidence, ±30%), GPU-limited. For 60 fps at 1080p, use the low preset. The cheapest current card for 60 fps at 1080p high is the Radeon RX 6500 XT (~66 fps). Model estimate, not measured; data updated 2026-09-24.

Estimate · low confidence, ±30%

Estimated FPS from our model (v0), based on the game's published requirements and relative GPU/CPU performance. Not measured. Real results vary with drivers, patches, and scenes. Values above 300 fps show as 300+. Data updated 2026-09-24.

Best settings

60 fps at 1080p: low preset
60 fps at 1440p: not reachable
144 fps at 1080p: not reachable

AMD card: use FSR in quality mode before dropping the preset (XeSS also works). DLSS is not available on Radeon.

What limits performance

Estimates above: GPU-limited, assuming a processor fast enough not to hold the Radeon HD 7870 back.
Processor needed for ~43 fps: Core i3-9100F or faster (slowest current desktop CPU our model expects to keep up).

Video memory

Radeon HD 7870: 2 GB
