Steamworld Build

Steamworld Build is a city builder that scales unusually hard with resolution, and the Intel Core i5-14400F + NVIDIA GeForce RTX 5080 combination reveals a system that is heavily GPU-bound at higher settings, yet surprisingly capable of extreme frame rates at lower presets. The data shows a clear pattern: at 1080p Low, the combo delivers 329 FPS average, but at 4K Ultra, it drops to 54 FPS average. This six-fold spread demonstrates that the RTX 5080's raw throughput is the primary lever on performance, while the i5-14400F provides sufficient headroom to avoid becoming a bottleneck until frame rates exceed the 300 FPS mark. The following analysis breaks down the measured results across every resolution and preset, contextualizes the CPU and GPU roles using benchmark data, and offers practical settings guidance.

Resolution Scaling

The frame rate curve from 1080p to 4K is steep and consistent, indicating that Steamworld Build's rendering pipeline places increasing stress on the GPU as pixel count rises. At High settings, the average FPS falls from 236 at 1080p to 150 at 1440p (a 36% reduction) and then to 79 at 4K (a 47% reduction from 1440p). This is a classic sign of pixel-bound rendering, where the RTX 5080's 960.0 GB/s memory bandwidth and 56.28 TFLOPS FP32 compute are the limiting factors. The resolution scaling is non-linear, with the 4K drop being more severe than the 1440p drop, which suggests that memory bandwidth saturation begins to occur beyond 1440p.

At Low settings, the scaling pattern shifts. The 1080p result of 329 FPS drops to 262 FPS at 1440p (a 20% reduction) and then to 139 FPS at 4K (a 47% reduction from 1440p). The smaller 1080p-to-1440p drop indicates that at lower settings, the CPU begins to play a more significant role, as the i5-14400F's 10 cores and 16 threads can feed frames up to around 300 FPS. However, the 4K Low result of 139 FPS shows that even with minimal graphical load, the GPU still dominates at higher resolutions. The data suggests that the sweet spot for this combo is 1440p, where the CPU and GPU balance is most favorable.

The Ultra preset reveals the most dramatic scaling. At 1080p Ultra, the combo achieves 159 FPS, but this falls to 101 FPS at 1440p (a 36% reduction) and then to 54 FPS at 4K (a 47% reduction). This consistent 36-47% drop pattern across all settings confirms that resolution is the single largest performance variable in this game, and the RTX 5080's 16 GB of GDDR7 memory is sufficient to handle the data footprint at all tested resolutions without capacity-related stutters.

GPU Role

The NVIDIA GeForce RTX 5080 is the dominant component in this pairing, and its influence is visible across every resolution and preset. The GPU's 16 GB of GDDR7 memory on a 256-bit bus provides 960.0 GB/s of bandwidth, which is sufficient to feed the 10752 shading units at all tested settings. The boost clock of 2617 MHz, combined with the 112 ROPs and 336 TMUs, allows the card to maintain high fill rates even at 4K, though the data shows that Ultra settings cause the biggest performance penalty.

In synthetic benchmarks, the RTX 5080 achieves a Passmark G3D score of 36565 and a Geekbench Vulkan score of 255450, placing it in the 87th percentile of all GPUs. Its average benchmark score of 56083 is 0.6% higher than the AMD Radeon 8060S (55757) and 0.7% higher than the AMD Radeon RX 6750 GRE 12 GB (55698), but 2.2% lower than the AMD Radeon RX 9070 GRE (57367). This mid-range positioning explains why Steamworld Build's 4K Ultra result (54 FPS) is respectable but not exceptional, as the card sits between higher and lower performing rivals.

The VRAM capacity of 16 GB is never a limiting factor in the measured data. Even at 4K Ultra, where texture memory usage would be highest, the average FPS of 54 indicates that the GPU is compute-bound rather than memory-bound. The GDDR7 memory clock of 1875 MHz (30 Gbps effective) provides ample bandwidth for the game's city-building visuals, which feature dense geometry and numerous objects that benefit from high texture throughput.

Measured FPS Breakdown

At 1920x1080, the system delivers exceptional performance across all presets. Low settings yield 329 FPS average, which is the highest measured result in the entire dataset. Medium settings produce 298 FPS average with a minimum of 254 FPS and maximum of 343 FPS, showing excellent frame pacing. High settings drop to 236 FPS, while Ultra settles at 159 FPS. These results indicate that at 1080p, the RTX 5080 is never the bottleneck; instead, the CPU's ability to feed the GPU becomes the limiting factor, as evidenced by the narrowing gap between Low and Medium (31 FPS difference) compared to the gap between High and Ultra (77 FPS difference).

At 2560x1440, the performance remains strong but shows a more pronounced GPU influence. Low settings deliver 262 FPS, which is a 20% reduction from 1080p. Medium settings hit 201 FPS average with a minimum of 171 FPS and maximum of 231 FPS, making it the most consistent 1440p option. High settings achieve 150 FPS, while Ultra drops to 101 FPS. The 1440p results show a clearer separation between presets, with the gap between Low and Medium (61 FPS) being nearly double the gap at 1080p, indicating that the GPU is beginning to work harder as pixel count increases.

At 3840x2160, the system's limits become apparent. Low settings deliver 139 FPS, which is a 47% reduction from 1440p. Medium settings drop to 106 FPS average with a minimum of 90 FPS and maximum of 122 FPS, representing the only 4K preset with a recorded minimum above 60 FPS. High settings fall to 79 FPS, while Ultra bottoms out at 54 FPS. The 4K data shows that even the RTX 5080 cannot maintain high refresh rates at maximum detail, but it does offer a playable experience at Medium settings.

CPU Role

The Intel Core i5-14400F provides the computational foundation for this system, and its 10 cores (6 performance and 4 efficiency) with 16 threads are well-suited for Steamworld Build's city-building simulation logic.
