Can My RX 7800 XT Run Sea of Thieves? FPS Estimate & System Requirements (2026)

The RX 7800 XT is a natural fit for Sea of Thieves at 1440p: about 76 FPS there and 115 FPS at 1080p. Native 4K is possible only with upscaling, not smooth Ultra. Note that Sea of Thieves is CPU-bound at high frame rates, so on a RX 7800 XT the processor — not the GPU — decides how high your average FPS actually climbs.

On a RX 7800 XT, aim for 1440p (QHD) in Sea of Thieves. The RX 7800 XT is a natural fit for Sea of Thieves at 1440p: about 76 FPS there and 115 FPS at 1080p. Native 4K is possible only with upscaling, not smooth Ultra. Note that Sea of Thieves is CPU-bound at high frame rates, so on a RX 7800 XT the processor — not the GPU — decides how high your average FPS actually climbs.

Unlike most titles, Sea of Thieves leans on the processor more than the RX 7800 XT. At 1080p you can already be CPU-limited, so a faster RX 7800 XT gives diminishing returns — spend the budget on a stronger CPU or faster RAM. The RX 7800 XT has more than enough pixel-pushing power for Sea of Thieves.

The limiting factor for this specific pairing is your CPU. Sea of Thieves spends most of its frame budget on the processor (entity counts, physics, draw calls), so the RX 7800 XT — a high-end card at relative index 73/100 — rarely reaches its own limit. Upgrading the CPU yields more FPS than upgrading the GPU here.

Sea of Thieves is assigned a hardware-demand tier 5/9 from its published requirements (or release era + genre). Each GPU has a relative-performance index (RTX 4090 = 100, source TechPowerUp). FPS ≈ 60 × (GPU index ÷ required index)^0.85, then scaled ×0.66 for 1440p and ×0.38 for 4K. FPS figures are editorial estimates from a transparent demand-tier model (TechPowerUp relative-performance indices, retrieved 2026-08-29), not benchmarks. Verify with your own hardware.
