Steamworld Build

Steamworld Build is a city builder that leans less on raw GPU muscle and more on sustained CPU throughput, and the pairing of the AMD Ryzen 5 3600 with the NVIDIA GeForce RTX 3080 produces a distinctive performance curve. The data shows a setup that is heavily CPU-bound at lower resolutions, with the RTX 3080’s headroom only becoming apparent as the pixel count climbs. The measured results across the three resolutions and four quality presets reveal a component dynamic where the 6-core, 12-thread Zen 2 processor dictates the ceiling, while the Ampere GPU ensures that visual fidelity scaling does not introduce severe bottlenecks.

Resolution Scaling

The transition from 1080p to 4K demonstrates a classic case of a GPU that is waiting for the CPU to catch up. At 1920x1080 with Low settings, the combo produces 229.5 FPS, but this is not evidence of the RTX 3080’s power—it is the point where the Ryzen 5 3600’s single-thread performance, with a boost clock of 4.20 GHz, becomes the limiting factor. Moving to 2560x1440 Low, the frame rate drops to 188.9 FPS, a 17.7% reduction, which is relatively modest and indicates the GPU is still not fully engaged. The real scaling begins at 3840x2160 Low, where the average falls to 97.2 FPS, a 48.5% decrease from the 1440p result. This steep drop signals that the RTX 3080’s 10 GB of GDDR6X memory and 760.3 GB/s bandwidth are finally being taxed, while the CPU has more breathing room.

The scaling pattern shifts dramatically with higher settings. At Ultra, the 1080p result is 117.4 FPS, and 1440p drops to 73 FPS, a 37.8% decline. The 4K Ultra figure of 37.9 FPS represents a further 48.1% reduction from 1440p, showing that the GPU is now the primary constraint. The gap between Low and Ultra at 4K is substantial—97.2 FPS versus 37.9 FPS—which suggests that the RTX 3080’s 8704 shading units and 68 RT cores are being pushed hard by the game’s draw calls and simulation logic. The data indicates that this combo is balanced for 1440p High, where the 110.1 FPS result keeps the CPU and GPU in relative harmony, but at 1080p, the CPU holds the system back from exploiting the GPU’s full potential.

FAQ

Q: What is the maximum average frame rate this combo achieves in Steamworld Build?

A: The highest recorded average is 229.5 FPS at 1920x1080 with Low settings, which represents the CPU-bound ceiling for this pairing.

Q: How does the combo perform at 4K Ultra settings?

A: At 3840x2160 with Ultra settings, the average FPS drops to 37.9, indicating that the RTX 3080 is the limiting factor at this extreme preset.

Q: Is the Ryzen 5 3600 or the RTX 3080 the bottleneck at 1080p Medium?

A: At 1080p Medium, the system produces 208.4 FPS, which is close to the Low-setting result of 229.5 FPS, suggesting the CPU’s multi-threaded performance (Cinebench R23 multi-core score of 15045) is the primary constraint.

Q: What is the difference in performance between 1440p High and 4K High?

A: The 1440p High average is 110.1 FPS, while 4K High drops to 56.9 FPS, a 48.3% reduction that highlights the GPU’s workload increase at higher pixel counts.

Q: Does the RTX 3080’s memory bandwidth help at lower resolutions?

A: The 760.3 GB/s bandwidth is underutilized at 1080p, where the CPU holds the system back, but it becomes critical at 4K where the 10 GB frame buffer is more heavily utilized.

Q: How does this combo compare to other tested configurations?

A: The combo ranks 613 out of 1730 tested combinations, placing it in the upper third of all pairings for this game.

GPU Role

The NVIDIA GeForce RTX 3080 plays a secondary role at lower resolutions but becomes the star performer as the resolution increases. The GPU’s base clock of 1440 MHz and boost clock of 1710 MHz, paired with its 10 GB of GDDR6X memory on a 320-bit bus, provide the raw throughput needed for high-fidelity rendering. In Steamworld Build, the game’s simulation-heavy nature means the GPU’s 8704 shading units are not always fully utilized, particularly at 1080p where the CPU’s 6 cores and 12 threads are the limiting factor. The passmark G3D score of 25086 and the 3DMark Steel Nomad DX12 score of 4407 confirm the GPU’s capability, but the benchmark results show that this power is only realized at 4K.

The VRAM allocation is telling. At 4K Ultra, the frame rate drops to 37.9 FPS, which is a 60.8% reduction from the 4K Low result of 97.2 FPS. This suggests that the game’s asset streaming and texture compression are heavily dependent on the 10 GB frame buffer, and the RTX 3080’s 68 RT cores and 272 tensor cores, while not directly relevant to a city builder, contribute to the overall graphics pipeline. The GPU’s 29.77 TFLOPS FP32 performance is more than sufficient for the game’s shader complexity, but the data indicates that the bottleneck at 4K High (56.9 FPS) and 4K Ultra is likely the memory bandwidth and the sheer number of pixels being processed. The GPU’s role shifts from being underutilized at 1080p to being the sole determinant of performance at 4K, with the CPU’s influence waning as resolution climbs.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of how this combo scales across settings and resolutions. At 1920x1080, the results are: Low 229.5 FPS, Medium 208.4 FPS, High 169.3 FPS, and Ultra 117.4 FPS. The drop from Low to Ultra is 48.9%, which is a significant penalty for higher visual quality, but the absolute numbers remain playable. The 1440p results show a similar pattern: Low 188.9 FPS, Medium 147.9 FPS, High 110.1 FPS, and Ultra 73 FPS. The jump from High to Ultra at 1440p is a 33.7% reduction, which is steeper than the 30.7% drop seen at 1080p from High to Ultra, indicating that the GPU is starting to feel the pressure.

At 4K, the breakdown is more dramatic: Low 97.2 FPS, Medium 74.5 FPS, High 56.9 FPS, and Ultra 37.9 FPS. The 4K Ultra result is the only one that dips below 60 FPS, which would be a concern for smooth gameplay on a 60 Hz display. The scaling from Low to Ultra at 4K is a 61% reduction, which is the steepest of any resolution. This suggests that the RTX 3080 is being pushed to its limits, and the 10 GB VRAM may be insufficient for the Ultra preset’s higher-resolution textures. The data shows that the combo is most comfortable at 1440p High, where the 110.1 FPS result provides a solid balance between visual fidelity and frame rate, while 4K gaming requires accepting Medium settings or lower to maintain acceptable performance.

How This Combo Ranks

With a rank of 613 out of 1730 tested combinations, this pairing of the AMD Ryzen 5 3600 and NVIDIA GeForce RTX 3080 sits in the upper third of all configurations for Steamworld Build. The rank reflects a system that is capable but not top-tier, primarily due to the CPU’s age. The Ryzen 5 3600, with a percentile rank of 76 among all CPUs, is a solid mid-range processor, but its nearest rivals show how close the competition is: the Intel Core i5-11400 is only 0.1% behind in average benchmark score, while the AMD Ryzen 5 7535HS is 0.2% ahead. This tight grouping means that the CPU’s performance is highly dependent on the specific workload, and in Steamworld Build, the multi-threaded demands of the simulation engine are well-served by the 12 threads.

The GPU’s percentile rank of 80 places it above the CPU, and its nearest rivals include the AMD Radeon RX 7900 GRE (0.9% behind) and the NVIDIA GeForce RTX 5070 Ti Mobile (1% ahead). This suggests that the RTX 3080 is still a competitive GPU, but the overall combo rank is dragged down by the CPU’s limitations. The data implies that pairing this GPU with a newer, faster CPU would likely push the combo significantly higher in the rankings, as the 1080p results are clearly CPU-bound. The rank of 613 out of 1730 indicates that there are over 600 combinations that perform better, but also over 1,100 that perform worse, placing this setup in a comfortable position for 1440p gaming and playable 4K at reduced settings.
