Steamworld Build

Steamworld Build is a city builder that rarely behaves like a traditional first-person shooter benchmark, and the data for the AMD Ryzen 7 7700 + NVIDIA GeForce RTX 5090 configuration confirms this. The pairing produces a massive performance envelope, but the way frame rates scale across resolutions reveals a system that is heavily bound by game logic and CPU throughput at lower settings, while the GPU takes over as the primary constraint only at the most demanding presets.

Resolution Scaling

The measured frame rates show an unusual pattern for a modern title. At 1080p with Low settings, the combo achieves 358.5 FPS, but dropping to 1440p Low only reduces this to 290.1 FPS, and at 4K Low it still holds 150.5 FPS. This scaling is far from linear: moving from 1080p to 1440p costs roughly 19% performance, while moving from 1440p to 4K costs another 48%. The relatively modest drop at 1440p suggests that the CPU, with its 8 cores and 16 threads, is still feeding the GPU adequately at that resolution, but the 4K Low result indicates the RTX 5090’s raw rasterization power is beginning to be the limiting factor.

At High settings, the pattern shifts. The 1080p result is 263.8 FPS, 1440p drops to 163.8 FPS, and 4K falls to 87.9 FPS. The percentage drop from 1080p to 1440p is now 38%, and from 1440p to 4K is 46%. The 4K High figure of 87.9 FPS is still very playable, but the scaling curve shows that the game’s visual effects at High settings place a much heavier load on the GPU’s shading units and memory subsystem. The RTX 5090’s 32 GB of GDDR7 memory and 1.79 TB/s bandwidth are clearly not being saturated at 1080p, but they become relevant as resolution climbs.

The Ultra preset is where the GPU truly takes over. At 1080p Ultra, the average is 178 FPS; at 1440p Ultra, it falls to 114.1 FPS; and at 4K Ultra, it bottoms out at 59 FPS. The drop from 1080p to 1440p is 36%, and from 1440p to 4K is 48%. This is a classic GPU-bound scaling pattern, where the RTX 5090’s 104.8 TFLOPS of FP32 compute is being fully utilized. The 4K Ultra result of 59 FPS is exactly at the edge of the 60 FPS target, suggesting that the combination of high resolution and maximum settings is the first point where this flagship GPU starts to feel challenged by Steamworld Build’s engine.

GPU Role

The NVIDIA GeForce RTX 5090 is the dominant component in this pairing, and its specifications explain why it performs so well. The GPU features 21,760 shading units, 680 texture mapping units, and 176 ROPs, with a boost clock of 2407 MHz. Its memory configuration is equally impressive: 32 GB of GDDR7 on a 512-bit bus, delivering 1.79 TB/s of bandwidth. These numbers translate directly to the benchmark results. At 1080p Low, the GPU is effectively idle, producing 358.5 FPS, but the fact that it can still hit 150.5 FPS at 4K Low shows that even at minimal settings, the sheer pixel throughput required at 3840x2160 is substantial.

The RTX 5090’s 94th percentile ranking among all GPUs, with an average benchmark score of 84,306, places it near the top of the stack. Its nearest rival, the NVIDIA GeForce RTX 5090 D, scores 84,241, a delta of just 0.1%. This is essentially a tie, indicating that the standard RTX 5090 is performing exactly as expected. The AMD Radeon PRO W6600, which trails by 1.3%, is not in the same performance class, and the NVIDIA CMP 40HX actually leads by 1.6%, though that card is a mining-specific part with no display outputs.

In Steamworld Build, the GPU’s role becomes more pronounced at higher settings. The Ultra preset at 4K produces 59 FPS, which is the only measured result below 60 FPS. This is not a failure of the GPU but rather a reflection of the game’s engine drawing more complex geometry and shadows. The RTX 5090’s 170 ray tracing cores and 680 tensor cores are not directly relevant to a city builder’s rasterization workload, but the raw FP32 throughput and memory bandwidth are what allow it to maintain high frame rates even when the game’s simulation layer is active.

CPU Role

The AMD Ryzen 7 7700 is a 65 W, 8-core, 16-thread processor based on the Zen 4 architecture, with a base clock of 3.80 GHz and a boost clock of 5.30 GHz. Its 32 MB of shared L3 cache and 83.2 GB/s of dual-channel DDR5 memory bandwidth are modest by 2025 standards, but they are more than sufficient for a city builder. The CPU’s 91st percentile ranking among all processors, with an average benchmark score of 40,468, puts it in the upper tier of desktop chips. Its nearest rival, the AMD Ryzen 9 7940H, scores 40,431, a delta of just 0.1%, meaning the 7700 is effectively tied with a higher-tier mobile part.

The CPU’s influence on Steamworld Build is most visible at lower resolutions and settings. At 1080p Low, the system hits 358.5 FPS, which is likely near the engine’s simulation tick rate limit. The 16 threads allow the game to spread its population and resource simulation across multiple cores, and the 5.30 GHz boost clock ensures that single-threaded tasks, like pathfinding or UI updates, are handled quickly. The Cinebench R23 multicore score of 29,302 and single-core score of 4,136 support this interpretation: the CPU is strong enough to avoid becoming a bottleneck in most scenarios.

However, the data also shows that the CPU does not scale perfectly with the GPU’s capabilities. At 4K Ultra, the system drops to 59 FPS, and the CPU’s role becomes secondary to the GPU’s rendering load. The 3DMark 16-thread score of 8,484 and max-thread score of 8,479 are nearly identical, indicating that the CPU’s performance is consistent across workloads. This consistency is beneficial for a game like Steamworld Build, where frame times can spike during large-scale construction or when many units are active. The PassMark multithread score of 34,470 and integer math score of 110,295 further confirm that the CPU handles complex calculations without issue.

How This Combo Ranks

The AMD Ryzen 7 7700 + NVIDIA GeForce RTX 5090 combination ranks 14th out of 1,730 tested combos in Steamworld Build. This top-1% placement is expected given the components’ individual rankings: the CPU is in the 91st percentile of all processors, and the GPU is in the 94th percentile of all GPUs. The rank of 14 indicates that there are 13 other configurations that achieve higher average frame rates across the tested settings, but those are likely to feature even more powerful CPUs, such as the Ryzen 9 series or Intel Core i9 parts, which would provide a slight edge in the CPU-bound 1080p Low scenario.

The fact that this combo ranks 14th rather than higher is telling. The RTX 5090 is the second-fastest GPU in the database by average score, trailing only the NVIDIA CMP 40HX by a 1.6% margin. However, the Ryzen 7 7700, while excellent, is not the fastest CPU available. Its 8 cores and 16 threads are sufficient for Steamworld Build, but a 16-core or 24-core processor could push the 1080p Low result higher, potentially improving the overall combo rank. The data shows that at 1080p Low, the system produces 358.5 FPS, and it is plausible that a stronger CPU could push this toward 400 FPS, but the measured results are what they are.

In practical terms, the 14th rank out of 1,730 is a stellar outcome. It means that this pairing outperforms 99.2% of all tested configurations in this specific game. The gap between this combo and the top spot is likely small in absolute FPS terms, especially at higher resolutions where the GPU dominates. At 4K Ultra, the RTX 5090’s 59 FPS result is likely matched by any system with the same GPU, regardless of CPU, because the rendering load is so heavy. The CPU’s influence is confined to the lower-resolution, lower-settings presets, and the 7700 handles those admirably.
