Steamworld Build

Steamworld Build is a city builder that scales heavily with raw GPU throughput, and the AMD Ryzen 5 8400F + NVIDIA GeForce RTX 5090 combination delivers exceptional frame rates across all tested resolutions. The data shows that the RTX 5090's massive 32 GB VRAM pool and high clock speeds provide a substantial performance headroom, but the game's optimization means that even at 4K Ultra, the system maintains a playable 58.6 FPS average. This pairing ranks in the 98th percentile of all tested combos, making it a top-tier choice for this title, though the CPU's 6-core/12-thread configuration becomes a notable factor at lower resolutions where frame rates exceed 300 FPS.

Settings Recommendations

For the best balance of visual fidelity and smooth gameplay, the High preset at 2560x1440 is the optimal choice, delivering 168.2 FPS average. This setting provides a substantial improvement over Medium (223.6 FPS) in visual quality while still maintaining a frame rate well above the 144Hz refresh rate common in modern monitors. At 4K, the High preset yields 85.1 FPS, which is the ideal target for high-refresh-rate 4K displays, offering a 44% performance increase over Ultra while sacrificing minimal visual detail.

The Ultra preset is only recommended for players prioritizing maximum visual quality over frame rate. At 1920x1080, Ultra achieves 177.1 FPS, which remains highly playable, but at 4K it drops to 58.6 FPS. This 4K Ultra frame rate is borderline for competitive play but acceptable for a city builder where precise timing is less critical. The Medium preset offers diminishing returns at 1080p (299.7 FPS) and 1440p (223.6 FPS), providing a marginal performance boost over High without significant visual improvements in most scenes.

The Low preset is functionally irrelevant for this hardware combination, as it produces frame rates exceeding 329.8 FPS at 1080p and 282.6 FPS at 1440p. These numbers far exceed the refresh rate capabilities of virtually all displays, making the visual quality trade-off unnecessary. For 4K gaming, High is the definitive recommendation, as it provides a 45% performance advantage over Ultra while the visual differences between these presets are often imperceptible during active city management.

GPU Role

The NVIDIA GeForce RTX 5090 is the dominant component in this pairing, and its specifications directly explain the measured performance. The GPU's 32 GB of GDDR7 memory on a 512-bit bus provides a 1.79 TB/s bandwidth, which is crucial for Steamworld Build's asset streaming during city expansion. The 104.8 TFLOPS FP32 compute capability and 1,636.8 GTexel/s texture rate allow the card to handle complex geometry and texture-heavy scenes without bottlenecking, as evidenced by the high frame rates at all settings levels.

The GPU's clock behavior is notable: a base clock of 2017 MHz boosting to 2407 MHz. This aggressive boost clock, combined with the 176 ROPs, enables the card to sustain high pixel throughput (423.6 GPixel/s), which directly translates to the 329.8 FPS at 1080p Low. The RTX 5090's 94th percentile ranking among all GPUs in the database confirms its top-tier status, sitting 0.1% above the RTX 5090 D and 1.3% above the AMD Radeon PRO W6600 in synthetic benchmarks.

The GPU's 575 W TDP and 950 W suggested PSU indicate substantial power requirements, but the performance data justifies this. The measured FPS at 4K Ultra (58.6 FPS) versus 4K High (85.1 FPS) shows a 31% performance drop when enabling the highest preset, which is a typical scaling curve for this GPU architecture. The 32 GB VRAM allocation is never a limiting factor, as even at 4K Ultra, the card maintains consistent frame pacing without any indication of memory pressure.

How This Combo Ranks

This specific combination of AMD Ryzen 5 8400F and NVIDIA GeForce RTX 5090 ranks 31st out of 1,730 tested combos in Steamworld Build. This places the system in the top 1.8% of all configurations benchmarked for this game, demonstrating exceptional performance. The high ranking is primarily attributable to the RTX 5090's raw compute power, as the CPU's synthetic benchmark scores (25,064 average) place it in the 82nd percentile among all processors, which is good but not elite.

The combo's ranking is particularly impressive given the CPU's modest specifications. The Ryzen 5 8400F's 3DMark max-thread score of 6,165 and Cinebench R23 multi-core score of 20,851 are sufficient to feed the GPU at most resolutions, but the data suggests the CPU becomes a secondary bottleneck at 1080p Low where the system reaches 329.8 FPS. At 4K, the GPU's workload dominates, allowing the combo to achieve its 31st-place ranking, which is consistent with other high-end GPU pairings.

Compared to the CPU's nearest rivals, the Ryzen 5 8400F performs within 0.3% of the AMD Ryzen 5 7500F and within 0.1% of the AMD Ryzen AI 5 PRO 340. This indicates that the CPU choice has minimal impact on the final ranking, as the GPU's performance ceiling is the primary differentiator. The 31st-place ranking out of 1,730 combos means this system outperforms the vast majority of configurations, including many with more powerful CPUs paired with lesser GPUs.

Measured FPS Breakdown

At 1920x1080, the system delivers exceptional performance across all presets. The Low preset achieves 329.8 FPS, Medium achieves 299.7 FPS, High achieves 261.5 FPS, and Ultra achieves 177.1 FPS. The scaling from Low to Ultra shows a 46% performance reduction, indicating that the Ultra preset adds significant rendering complexity. All 1080p results are above 170 FPS, making this resolution ideal for competitive play or high-refresh-rate displays.

At 2560x1440, the performance remains robust. The Low preset reaches 282.6 FPS, Medium reaches 223.6 FPS, High reaches 168.2 FPS, and Ultra drops to 111.3 FPS. The transition from 1080p to 1440p results in a 14% frame rate reduction at Low settings and a 37% reduction at Ultra, showing that higher resolutions disproportionately impact the most demanding presets. The 1440p Ultra result of 111.3 FPS is still above the 100 FPS threshold for smooth gameplay.

At 3840x2160, the system shows its strengths and limitations. The Low preset achieves 150.5 FPS, Medium achieves 118 FPS, High achieves 85.1 FPS, and Ultra drops to 58.6 FPS. The 4K results demonstrate that the RTX 5090 can handle 4K gaming, but the Ultra preset requires compromises. The 4K High result of 85.1 FPS is the recommended sweet spot, providing a 45% performance improvement over Ultra while maintaining high visual fidelity.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals important insights about the system's bottleneck characteristics. At Low settings, the FPS drops from 329.8 at 1080p to 150.5 at 4K, representing a 54% reduction. This significant drop at low settings indicates that the GPU is the primary limiting factor, as the CPU is not heavily stressed at these settings. The 4K Low result of 150.5 FPS shows that the GPU's raw compute power is sufficient for high refresh rates even at 4K.

At High settings, the scaling shows a 67% FPS reduction from 1080p (261.5 FPS) to 4K (85.1 FPS). This steeper drop suggests that the increased pixel count and texture complexity at 4K impose a heavier load on the GPU's shading units and memory bandwidth. The 1.79 TB/s memory bandwidth is adequate, but the 4K Ultra result of 58.6 FPS indicates that the GPU is approaching its limits with the most demanding settings.

The Ultra preset shows the most dramatic scaling, with a 67% reduction from 1080p (177.1 FPS) to 4K (58.6 FPS). This pattern confirms that the GPU is the dominant component, as the CPU's performance headroom remains constant across resolutions. The data suggests that at 1080p and 1440p with lower presets, the CPU may provide occasional frame pacing limitations, but at 4K, the GPU is unequivocally the limiting factor.

CPU Role

The AMD Ryzen 5 8400F's 6 cores and 12 threads, based on the Zen 4 architecture, provide adequate processing power for Steamworld Build's simulation and logic systems. The CPU's boost clock of 4.70 GHz and 16 MB of shared L3 cache deliver solid single-thread performance, as evidenced by the 3DMark single-thread score of 951 and Cinebench R23 single-core score of 2,943. These scores are consistent with the CPU's 82nd percentile ranking, placing it in the upper tier of processors.

The CPU's multi-threaded capabilities, shown in the Cinebench R23 multi-core score of 20,851 and PassMark multi-thread score of 24,530, are sufficient for city builder workloads that typically utilize multiple threads for pathfinding and resource management. However, the data suggests that at 1080p with Low settings (329.8 FPS), the CPU's 12 threads become a potential bottleneck, as the frame rate approaches the CPU's maximum frame generation capacity.

The CPU's nearest rival, the AMD Ryzen 7 2700X, has an identical average benchmark score (25,057 vs 25,064), indicating that the 8400F's performance is comparable to a previous-generation 8-core processor. This is notable because the 8400F's 65 W TDP and 4 nm process node provide this performance in a more power-efficient package. The CPU's 12 threads and 4.70 GHz boost clock are well-matched for this game, as the measured FPS at 4K does not show any CPU-related frame drops, confirming that the GPU is the primary performance driver.
