Steamworld Build

Steamworld Build, a city builder from late 2023, presents a unique scaling challenge for the AMD Ryzen 7 5800X paired with the Intel Arc B580. The measured frame rates across resolutions and presets reveal a system that is dramatically sensitive to graphics settings, with the gap between Low and Ultra widening significantly as resolution increases. This analysis interprets the data to identify where the bottleneck lies and which configurations deliver the most stable experience.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep and non-linear, indicating that the Intel Arc B580 becomes the primary limiting factor at higher resolutions. At Low settings, the transition from 1920x1080 (181 avg FPS) to 2560x1440 (117.4 avg FPS) represents a 35% performance loss, while moving from 1440p to 3840x2160 (60.9 avg FPS) incurs an additional 48% drop. This pattern suggests that at 1080p Low, the CPU is doing substantial work to feed frames, but as pixel count rises, the GPU's shading and memory bandwidth constraints dominate.

The scaling behavior becomes more extreme with higher presets. At Ultra settings, the drop from 1080p (70.9 avg FPS) to 1440p (44.7 avg FPS) is a 37% reduction, and further to 4K (20.6 avg FPS) is another 54% loss. This compounding effect at Ultra indicates that the B580's 13.67 TFLOPS of FP32 compute and 456.0 GB/s of memory bandwidth are being saturated by the combination of high-resolution rendering and intensive effects. The data shows that at 4K, the gap between Low (60.9) and Ultra (20.6) is a 66% spread, versus a 61% spread at 1080p, confirming that the GPU's workload scales super-linearly with resolution when settings are maxed.

Notably, the 1080p to 1440p transition at Medium (140 to 90.8 avg FPS) shows a 35% drop, while the 1440p to 4K transition (90.8 to 47.6 avg FPS) is a 48% drop. This asymmetry suggests that the B580's 12 GB of GDDR6 memory and 192-bit bus are adequate for 1440p but begin to struggle with the 4K framebuffer, especially when combined with medium-tier textures and effects. For players targeting 4K, the data clearly shows that only Low settings approach playability, while 1440p offers a viable middle ground for higher presets.

GPU Role

The Intel Arc B580, based on the Xe2-HPG architecture, plays a decisive role in Steamworld Build's performance envelope. Its base and boost clocks are both locked at 2670 MHz, a fixed frequency that ensures consistent behavior across workloads. The GPU's 2560 shading units, 160 TMUs, and 80 ROPs provide a balanced configuration for a city builder, where draw calls and texture fills are common. However, the benchmark results reveal that the card's raw compute is the limiting factor at higher presets, not the CPU.

The B580's memory subsystem is a critical component for this genre. With 12 GB of GDDR6 running at 2375 MHz (19 Gbps effective), the card delivers 456.0 GB/s of bandwidth across a 192-bit bus. This is sufficient for 1080p and 1440p at most settings, as evidenced by the 105.5 avg FPS at 1080p High and 68.6 avg FPS at 1440p High. However, at 4K Ultra, the combination of high-resolution textures and complex geometry pushes memory pressure to the limit, resulting in the 20.6 avg FPS figure. The pixel rate of 213.6 GPixel/s and texture rate of 427.2 GTexel/s are respectable, but they cannot compensate for the sheer pixel count at 3840x2160.

The B580's position in the GPU hierarchy, with a percentile ranking of 66 against all GPUs, aligns with its measured performance. Its average benchmark score of 23021 places it nearly identically to the AMD Radeon 760M (22999, deltaPct 0.1) and just 0.7% behind the NVIDIA GeForce RTX 4060 (23181). This suggests that the B580 is a solid mid-range performer, but Steamworld Build's Ultra preset appears to be disproportionately demanding on this architecture, given that the card trails its rivals by a small margin in synthetic tests yet exhibits such steep frame rate drops.

How This Combo Ranks

The combination of the Ryzen 7 5800X and the Arc B580 ranks 1333 out of 1730 tested combos in Steamworld Build. This places it in the lower-middle quartile of all CPU-GPU pairings, which is somewhat surprising given the individual components' specifications. The CPU, with its 8 cores and 16 threads based on Zen 3, achieves an average benchmark score of 27606 and sits at the 84th percentile among all CPUs. Its nearest rival, the AMD Ryzen 7 5800, scores 27535 (deltaPct 0.3), while the Intel Core i5-12600KF scores 27827 (deltaPct -0.8), indicating the 5800X is a capable processor.

However, the combo's low rank suggests that the B580's performance characteristics are not well-suited to this specific game's engine. The GPU's percentile ranking of 66 (against all GPUs) is notably lower than the CPU's 84, indicating that the graphics card is the bottleneck. This is corroborated by the frame rate data: at 1080p Low, the system achieves 181 avg FPS, which is excellent, but at 4K Ultra it drops to 20.6 avg FPS. The rank of 1333 out of 1730 suggests that many other combos, likely with more powerful GPUs, handle the Ultra preset more gracefully.

The delta percentages between the B580 and its nearest rivals are minimal (ranging from -0.7 to 1.3), yet the in-game performance shows a wide variance based on settings. This implies that Steamworld Build's Ultra preset may rely on features that are less optimized on Intel's Battlemage architecture, such as certain DX12 Ultimate paths (the GPU supports DirectX 12 Ultimate with version 12_2). The combo's rank, therefore, is more indicative of the GPU's limitations under high load rather than the CPU's processing power.

Measured FPS Breakdown

At 1920x1080, the system delivers a wide spectrum of performance. Low settings yield 181 avg FPS, which is exceptionally smooth and indicates that the CPU is not a limiting factor at this resolution. Medium settings produce 140 avg FPS, a 23% reduction from Low, while High settings result in 105.5 avg FPS, a 25% reduction from Medium. Ultra settings drop to 70.9 avg FPS, which is still playable but represents a 33% loss from High. This scaling pattern suggests that each preset tier adds a meaningful computational load, but even Ultra remains above the 60 FPS threshold for smooth gameplay.

At 2560x1440, performance degrades predictably but remains usable for most presets. Low settings achieve 117.4 avg FPS, which is a 35% drop from 1080p Low. Medium settings reach 90.8 avg FPS, a 35% drop from 1080p Medium. High settings produce 68.6 avg FPS, a 35% drop from 1080p High, while Ultra settings fall to 44.7 avg FPS, a 37% drop from 1080p Ultra. The consistency of the ~35% penalty across Low, Medium, and High indicates that the GPU's bandwidth is being scaled proportionally with pixel count, but the Ultra preset's additional effect load causes a slightly larger relative hit.

At 3840x2160, the system struggles to maintain playability except at Low settings. Low settings achieve 60.9 avg FPS, which is exactly at the threshold for smooth gameplay, representing a 48% drop from 1440p Low. Medium settings drop to 47.6 avg FPS, a 48% drop from 1440p Medium. High settings fall to 36.8 avg FPS, a 46% drop from 1440p High, while Ultra settings plummet to 20.6 avg FPS, a 54% drop from 1440p Ultra. The data shows that the 4K resolution is simply too demanding for this GPU at anything above Low, with the Ultra preset being nearly unplayable.

Settings Recommendations

Based on the measured FPS rows, the optimal experience depends heavily on the target resolution. For 1920x1080, the High preset at 105.5 avg FPS offers the best balance of visual quality and performance, as it remains well above 60 FPS while providing a richer visual experience than Low or Medium. The Ultra preset at 70.9 avg FPS is also viable for players who prioritize maximum visual fidelity, as it maintains a playable frame rate.

For 2560x1440, the High preset at 68.6 avg FPS is the recommended choice, as it delivers smooth gameplay while keeping the frame rate above the 60 FPS mark. The Medium preset at 90.8 avg FPS is a strong alternative for those who prefer higher frame rates, while the Low preset at 117.4 avg FPS is ideal for competitive or highly responsive play. The Ultra preset at 44.7 avg FPS is not recommended, as it falls below the smoothness threshold.

For 3840x2160, the Low preset at 60.9 avg FPS is the only viable option, and it barely meets the 60 FPS standard. Players targeting 4K should either accept Low settings or consider reducing the resolution to 1440p for a better visual experience. The Medium preset at 47.6 avg FPS and High preset at 36.8 avg FPS are playable for less demanding users, but the Ultra preset at 20.6 avg FPS is effectively a slideshow and should be avoided. In summary, the data indicates that this combo is best suited for 1080p High or 1440p High, with 4K reserved for Low settings only.
