Steamworld Build

Steamworld Build, a city builder from late 2023, presents a unique challenge for hardware, demanding strong single-thread performance for simulation logic and a capable GPU for rendering. The combination of the AMD Ryzen 7 9850X3D processor with the Intel Arc B390 integrated graphics produces a dataset that clearly illustrates the bottleneck dynamics of this genre. The measured frames per second (FPS) across resolutions and settings show a system where the CPU’s immense processing power is consistently held back by the GPU’s limited graphical throughput.

Resolution Scaling

The FPS data reveals a stark dependency on resolution, which is the primary indicator of where the performance ceiling lies. At 1920x1080 with Low settings, the combo achieves an average of 106 FPS, a figure that suggests the CPU is capable of feeding frames at a high rate. However, as resolution increases, the frame rate drops precipitously, indicating that the graphics processor is becoming the limiting factor. Moving from 1080p Low to 1440p Low, the average FPS falls from 106 to 67, a substantial reduction of 39 FPS. This trend continues to 4K (3840x2160) Low, where the average FPS plummets to 35, representing less than one-third of the 1080p performance.

This scaling pattern is classic for a system with a powerful CPU and a weak GPU. The load on the rendering hardware increases exponentially with pixel count, and the Intel Arc B390, with its System Shared memory and integrated design, cannot sustain high throughput at higher resolutions. The gap between Low and Ultra settings at each resolution further emphasizes this point. At 1080p, the difference between Low (106 FPS) and Ultra (41 FPS) is 65 FPS, showing the GPU is heavily taxed by graphical fidelity. At 4K, the difference narrows to 21 FPS (35 FPS Low vs. 14 FPS Ultra), but this is because the GPU is already so overwhelmed at Low settings that it has little headroom left to give; the absolute performance is in single digits to low twenties, making the game practically unplayable at 4K regardless of settings. The data strongly suggests that for playable frame rates, users must stay at 1080p or 1440p with moderate settings, as the GPU is the definitive bottleneck in this pairing.

How This Combo Ranks

Within the benchmark database, this specific combination of the AMD Ryzen 7 9850X3D and Intel Arc B390 ranks at 2573 out of 2924 tested combos for Steamworld Build. This places it in the bottom 12% of all configurations, which is a surprisingly low position given the caliber of the CPU. The ranking is a direct consequence of the GPU’s performance, as the combo’s overall score is dragged down by the graphics component's inability to keep pace with the processor.

The high rank number (with 1 being the best) indicates that the vast majority of other CPU-GPU pairings tested in this game deliver higher average frame rates. This is not a reflection of the CPU’s capability, but rather proof of how heavily the game’s performance is gated by the graphics solution. A system pairing this same CPU with a discrete graphics card would undoubtedly rank significantly higher, as the CPU’s benchmark scores (92nd percentile among all CPUs) are exceptional. The data shows that in this specific configuration, the whole is less than the sum of its parts; the powerful processor is effectively neutered by the integrated graphics, resulting in a combo that underperforms relative to its constituent hardware.

CPU Role

The AMD Ryzen 7 9850X3D is a formidable processor, featuring 8 cores and 16 threads based on the Zen 5 architecture. Its base clock of 4.70 GHz and boost clock of 5.60 GHz are high for a chip with a 120W TDP, and the large 96 MB of shared L3 cache is designed to improve gaming performance. In synthetic benchmarks, it scores 22,807 points in Cinebench R23 multi-core and 2,228 points in the single-core test, placing it in the 92nd percentile of all CPUs. This raw compute power is what allows the system to achieve 106 FPS at 1080p Low, where the CPU is not waiting on the GPU to render simple frames.

In a city builder like Steamworld Build, the CPU is responsible for simulating the game world, including the AI of citizens, resource management, and pathfinding. These tasks are often single-threaded or lightly threaded, meaning the high single-core performance of the 9850X3D is critical. The PassMark single-thread score of 4,704 supports this, as it is a strong indicator of the processor's ability to handle the game's simulation logic. However, the benchmark results show that the CPU’s role is to set the maximum possible frame rate, not to guarantee it. The measured FPS at higher resolutions shows that the CPU is rarely the limiting factor, as the frame rate drops are far too steep to be attributed to the processor. The CPU is ready and able to produce high FPS, but it is starved of work by the GPU, which cannot render frames fast enough to keep up with the processor's output.

Measured FPS Breakdown

The measured FPS data for this combo provides a clear picture of its capabilities across different settings and resolutions. At 1920x1080, the system is most comfortable. With Low settings, it achieves an average of 106 FPS, indicating a playable experience. Medium settings lower this to 81 FPS, with a minimum of 69 and a maximum of 93 FPS, showing some frame time variance. High settings yield 60 FPS, which is a solid target for many gamers. However, Ultra settings bring the average down to 41 FPS, which may introduce noticeable stutter in a simulation-heavy game.

Moving to 2560x1440, the performance drops significantly. Low settings produce an average of 67 FPS, a substantial decrease from 1080p. Medium settings average 51 FPS (min 44, max 59), while High settings drop to 38 FPS. Ultra settings at 1440p are largely unplayable, with an average of just 26 FPS. At 3840x2160, the system struggles across the board. The only setting that approaches playability is Low, with an average of 35 FPS. Medium settings fall to 27 FPS (min 23, max 31), and High settings are at 20 FPS. Ultra settings at 4K are a slideshow, with an average of only 14 FPS. The data shows a clear pattern: the system is only capable of providing a consistently smooth experience at 1080p with lower-to-mid settings. The minimum FPS data points for Medium settings (69 at 1080p, 44 at 1440p, 23 at 4K) also suggest that even at these settings, there are occasional hitches, which can be detrimental in a game where the simulation is constantly running.

GPU Role

The Intel Arc B390 is an integrated graphics processor, part of the Panther Lake generation, built on Intel's 3 nm process. It features 1536 shading units, 48 texture mapping units, and 24 raster output pipelines. Its boost clock is 2500 MHz, and it relies on System Shared memory, meaning its bandwidth is dependent on the system's DDR5 RAM. This is a fundamental limitation for gaming, as the GPU must share memory bandwidth with the CPU. Its performance is reflected in its 3DMark Steel Nomad DX12 score of 1,482, which places it in the 9th percentile of all GPUs, putting it in the same performance class as the NVIDIA GeForce GT 710 and GT 625 OEM.

The GPU’s role in this system is to be the primary bottleneck. The benchmark results show that in nearly every scenario, the frame rate is limited by the GPU’s rendering capabilities, not the CPU. For example, at 1080p Low, the GPU is able to produce 106 FPS, but at 4K Low, it only manages 35 FPS. This is purely a function of the GPU's fill rate and memory bandwidth being insufficient for the increased pixel count. The 7.680 TFLOPS of FP32 performance is simply not enough to handle the demands of Steamworld Build at high resolutions. The data indicates that the GPU is the component that dictates the playability of this game. Users looking to improve performance in this specific combo would need to replace the integrated graphics with a discrete solution, as the CPU is clearly not the limiting factor. The GPU’s performance is consistently below the CPU’s output, capping the FPS at levels that are far lower than what the processor is capable of supporting.
