Steamworld Build

Steamworld Build is a city builder where simulation logic and draw calls tend to scale with population and map complexity, making the balance between processor and graphics card critical. The Intel Core i5-12400 paired with the NVIDIA GeForce RTX 3080 produces a dataset that clearly delineates where each component’s influence begins and ends. This analysis breaks down the measured performance across resolutions and presets to explain what the numbers indicate about this specific hardware combination.

CPU Role

The Intel Core i5-12400 is a 6-core, 12-thread processor from the Alder Lake architecture, with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. Its 18 MB of shared L3 cache and support for DDR4 and DDR5 memory position it as a mid-range desktop part, and its benchmark profile shows strong multi-threaded capability with a Cinebench R23 multi-core score of 15935 and a single-core score of 2249. For Steamworld Build, the CPU’s role is primarily managing the game’s simulation logic, pathfinding, and the overhead of rendering many individual entities on screen.

The data suggests that at lower resolutions and settings, the CPU becomes a significant factor. At 1080p Low, the combo achieves 301 FPS, which is a massive jump from the 190.4 FPS seen at 1440p Low. This 58% increase indicates that at 1080p, the RTX 3080 is not the bottleneck; the i5-12400 is feeding frames fast enough to keep the GPU from being idle. The CPU’s PassMark multi-thread score of 18747 and its average benchmark score of 19850 place it in the 77th percentile of all CPUs, which is respectable but not top-tier. Compared to its nearest rivals, the Intel Core i7-9700 (scoring 19831, a 0.1% delta) and the Intel Core i5-11600K (scoring 19771, a 0.4% delta), the i5-12400 is essentially performance-equivalent. This means that in CPU-bound scenarios, such as the 1080p Low test, the i5-12400 is delivering performance in line with those older flagship parts, but it lacks the headroom that a higher-core-count processor might offer for massive late-game cities.

The benchmark results indicate that the CPU’s 6-core/12-thread configuration is sufficient to prevent stuttering in most scenarios, but the scaling from 1440p to 1080p at Low settings shows a 58% frame rate increase, suggesting that the processor is not the limiting factor there. However, as settings increase to Ultra, the frame rate at 1080p drops to 113.4 FPS, which is a 62% reduction from Low. This reduction is largely due to the GPU struggling with higher graphical loads, but it also shows that the CPU can maintain a high enough frame rate to allow the GPU to become the primary constraint. The i5-12400’s single-thread performance, with a 3DMark single-thread score of 910, is adequate for the game’s simulation ticks, ensuring that the game logic does not become a bottleneck at the tested settings.

GPU Role

The NVIDIA GeForce RTX 3080 is a high-end Ampere architecture GPU with 10 GB of GDDR6X memory on a 320-bit bus, providing 760.3 GB/s of bandwidth. Its boost clock of 1710 MHz and 8704 shading units give it substantial raw compute power, reflected in a PassMark G3D score of 25086 and a 3DMark Steel Nomad DX12 score of 4407. This places the GPU in the 80th percentile of all GPUs, with an average benchmark score of 35787. Its nearest rivals include the AMD Radeon RX 7900 GRE (scoring 36101, a -0.9% delta) and the NVIDIA GeForce RTX 5070 Ti Mobile (scoring 35435, a 1% delta), indicating that the RTX 3080 is still competitive with newer mid-range offerings.

In Steamworld Build, the GPU’s role becomes dominant as resolution and settings increase. The 10 GB VRAM is sufficient for the game’s textures at 4K, as the measured data shows a playable 54.4 FPS at 4K High. The GPU’s performance scaling is clear when comparing the 1080p Ultra score of 113.4 FPS to the 4K Ultra score of 41.1 FPS, a 64% drop. This steep decline shows that the RTX 3080 is heavily taxed by the combination of high resolution and Ultra settings, likely due to the increased pixel count and more complex shading. The GPU’s 760.3 GB/s memory bandwidth is critical here, as city builders often have large texture assets and many draw calls that require high memory throughput. The data shows that at 1440p Ultra, the combo hits 72.7 FPS, which is a solid result, but at 4K Ultra, it falls below the 60 FPS threshold, indicating that the GPU is the absolute limiting component at that extreme setting.

The RTX 3080’s compute capability, with a FP32 throughput of 29.77 TFLOPS, is more than enough for the game’s visual effects, but the VRAM capacity and bandwidth are what allow it to maintain high frame rates at 1440p. The drop from 1440p High (109.3 FPS) to 4K High (54.4 FPS) is a 50% reduction, which aligns with the pixel count difference and suggests that the GPU is scaling as expected. The GPU’s performance is not near its rivals in this game, as it holds a slight edge over the Radeon RX 7900 GRE in average benchmark scores, but the measured FPS indicates that it is more than capable of delivering a smooth experience at 1440p with High settings.

Resolution Scaling

The measured FPS data reveals how the balance shifts from CPU to GPU dominance as resolution climbs. At 1080p Low, the combo produces 301 FPS, which is exceptionally high and indicates that neither component is being fully utilized, as the CPU is likely hitting its frame generation limit while the GPU is underutilized. Moving to 1440p Low, the frame rate drops to 190.4 FPS, a 37% decrease, which is more than the pixel count increase (which is about 78% more pixels). This suggests that the GPU is starting to take on more work, but the CPU is still keeping pace.

At 1080p High, the frame rate is 169.2 FPS, which drops to 109.3 FPS at 1440p High, a 35% reduction. This consistent scaling pattern indicates that the RTX 3080 is now the primary bottleneck, as the CPU is able to feed frames faster than the GPU can render them. The biggest divergence occurs at 4K. At 4K Low, the combo hits 99.8 FPS, which is a 48% drop from 1440p Low. This is a significant drop, but it is still above 60 FPS, showing that the GPU can handle 4K with reduced settings. However, at 4K High, the frame rate falls to 54.4 FPS, and at 4K Ultra, it drops to 41.1 FPS.

The scaling from 1080p to 4K at each setting shows a clear trend. For Low settings, the drop from 1080p to 4K is 67% (from 301 to 99.8 FPS), while for High settings, the drop is 68% (from 169.2 to 54.4 FPS), and for Ultra, the drop is 64% (from 113.4 to 41.1 FPS). This consistency suggests that the GPU is the limiting factor across all settings at higher resolutions. The data indicates that the i5-12400 is strong enough to avoid becoming a bottleneck even at 4K Low, where the CPU is still able to maintain a frame rate of 99.8 FPS. The limiting component is definitively the GPU at 1440p and above, as the frame rate scaling aligns closely with the increase in pixel count. At 1080p Ultra, the CPU is still not a major constraint, as the 113.4 FPS result is high, but the GPU is clearly being pushed harder than at lower settings.

Settings Recommendations

The measured rows provide a clear hierarchy of performance across presets. At 1080p, all settings are playable, with Ultra delivering 113.4 FPS, which is smooth for a city builder. Medium settings at 1080p yield 227.9 FPS, which is excessive for this genre, but it shows the headroom available. For a balanced experience at 1080p, the data suggests that High settings (169.2 FPS) offer a strong visual upgrade over Low (301 FPS) without a proportional frame rate loss, as the drop is only 44%. The Ultra preset at 1080p is still viable, but the jump from High to Ultra only reduces the frame rate by 33%, which may not be worth the visual gains if the user prefers higher refresh rates.

At 1440p, the recommendation shifts. Ultra produces 72.7 FPS, which is above the 60 FPS threshold and is the best experience for visual fidelity. High settings at 1440p yield 109.3 FPS, which is a 50% increase over Ultra, but the visual difference between High and Ultra in a city builder is often subtle, involving shadow quality and ambient occlusion. The data shows that Medium settings at 1440p provide 145 FPS, which is excellent for high-refresh-rate monitors, but it sacrifices some texture and lighting quality. The sweet spot for 1440p is High, as it balances visual quality with a frame rate that comfortably exceeds 100 FPS, ensuring smooth panning and zooming.

At 4K, the choices are more constrained. Ultra settings drop to 41.1 FPS, which is below the playability threshold for most users, as city builder games require smooth camera movement to manage large maps. High settings at 4K produce 54.4 FPS, which is close to 60 FPS but may still show minor stutters during heavy simulation loads. Medium settings at 4K yield 77.2 FPS, which is a much better experience, and Low settings hit 99.8 FPS. Given the data, the best experience at 4K is Medium, as it provides a 42% frame rate improvement over High while maintaining acceptable visual quality. The Ultra preset at 4K is not recommended based on the measured 41.1 FPS, as it is likely to feel sluggish. The 1440p High preset offers the best balance of visual fidelity and performance across all resolutions, as it delivers 109.3 FPS, which is high enough for any display, and the settings are visually rich.

How This Combo Ranks

The combination of the Intel Core i5-12400 and NVIDIA GeForce RTX 3080 ranks 505th out of 1730 tested combos in Steamworld Build, placing it in the top 29% of all configurations. This rank is respectable, given that the CPU is a mid-range part and the GPU is a previous-generation high-end model. The ranking is influenced by the fact that the game is more GPU-bound at higher resolutions, which allows the RTX 3080 to show its strength, but the CPU’s performance is not holding the combo back significantly.

The rank of 505 out of 1730 indicates that there are many combos with more powerful CPUs or newer GPUs that achieve higher frame rates, particularly at 1080p where the CPU matters more. However, the measured data shows that this combo is capable of delivering high frame rates at 1440p and playable frame rates at 4K, which puts it ahead of many lower-tier pairings. The CPU’s average benchmark score of 19850 places it near the Intel Core i7-9700 and i5-11600K, and the GPU’s average score of 35787 is near the AMD Radeon RX 7900 GRE. This combination of a 77th percentile CPU and an 80th percentile GPU results in a balanced system that does not have a glaring bottleneck, as evidenced by the consistent frame rate scaling.

The 505th rank is not a top-tier position, but it is a strong mid-table result. The data shows that the combo excels at 1440p High, where it achieves 109.3 FPS, which is likely above the average for all tested combos at that setting. The ranking also reflects that the RTX 3080’s 10 GB VRAM is sufficient for 4K, but the GPU’s raw compute power is not enough to handle Ultra settings at that resolution, which pushes the combo down in the rankings compared to systems with more powerful GPUs like the RTX 4090 or newer 40-series cards. The i5-12400’s performance is adequate, but it does not provide the extra headroom that a higher-core CPU might offer for simulation-heavy late-game scenarios, which could affect long-term playability. Overall, the combo ranks well for its component tier, and the measured FPS data confirms that it is a reliable option for playing Steamworld Build at 1440p with high settings, with the ability to step down to 4K Medium if needed.
