Steamworld Build

Steamworld Build places the AMD Ryzen 7 5800X and Intel Arc B370 combination in a challenging position. The data shows a system that can produce playable frame rates at lower resolutions but struggles significantly as pixel count climbs. This pairing of a strong 8-core CPU with a modest integrated-class GPU creates a distinct bottleneck profile that becomes increasingly apparent at higher graphical loads.

Resolution Scaling

The measured FPS data reveals a steep and consistent performance cliff as resolution increases from 1080p to 4K. At 1080p with High settings, the combo averages 55 FPS, which drops to 35 FPS at 1440p and further to 18 FPS at 4K. This represents a 36% reduction from 1080p to 1440p, and a 67% reduction from 1080p to 4K. The scaling pattern is remarkably linear, suggesting the GPU is the primary limiting factor throughout.

At Low settings, the resolution scaling is even more dramatic. The system delivers 95 FPS at 1080p, 61 FPS at 1440p, and 32 FPS at 4K. The 1080p to 1440p drop of 36% mirrors the High settings curve, but the 1440p to 4K drop of 48% is steeper, indicating that even at minimal graphical load, the GPU cannot maintain performance headroom as pixel count increases.

Medium settings show a similar trajectory: 73 FPS at 1080p, 46 FPS at 1440p, and 25 FPS at 4K. The min FPS values at Medium settings provide additional insight — 62 FPS at 1080p, 39 FPS at 1440p, and 21 FPS at 4K — with the gap between average and minimum widening at higher resolutions, suggesting frame time consistency degrades alongside raw throughput.

Ultra settings produce the most constrained results, with 37 FPS at 1080p, 23 FPS at 1440p, and 12 FPS at 4K. The 1080p to 1440p drop of 38% and the 1440p to 4K drop of 48% indicate that the GPU's rendering pipeline becomes saturated at Ultra, and the resolution scaling penalty compounds as settings increase.

The data indicates that 1080p is the only resolution where this combination approaches smooth gameplay across all settings, while 1440p requires Low settings for playable frame rates. 4K remains largely unplayable regardless of settings, with even Low failing to reach 33 FPS. The limiting component is clearly the Intel Arc B370, as the CPU's strong multi-threaded capabilities cannot compensate for the GPU's limited fill rate and shading throughput.

GPU Role

The Intel Arc B370 is an integrated graphics solution based on the Xe3-LPG architecture, built on Intel's 3 nm process. It features 1280 shading units, 40 texture mapping units, and 20 raster output units, with 10 ray tracing cores. The GPU operates at a base clock of 300 MHz and boosts to 2400 MHz, delivering 6.144 TFLOPS of FP32 performance and a pixel rate of 48.00 GPixel/s.

Memory is system shared, with bandwidth described as system dependent. This architecture means the GPU relies on the host system's DDR4 memory, which for the Ryzen 7 5800X provides 51.2 GB/s of dual-channel bandwidth. The shared memory configuration likely contributes to the performance degradation at higher resolutions, as the GPU competes with CPU workloads for memory bandwidth.

The GPU's benchmark performance places it in a low percentile. Its 3DMark Steel Nomad DX12 score of 1184 positions it at the 5th percentile of all GPUs, with nearest rivals including the ATI Mobility Radeon HD 5570 (1186, 0.2% faster), ATI Radeon HD 5770 (1190, 0.5% faster), and AMD Radeon HD 7650M (1192, 0.7% faster). The AMD FirePro M2000 trails by 1.4% with a score of 1168.

The GPU's 25 W TDP and IGP slot width indicate its integrated nature, with no power connectors and portable device dependent display outputs. Despite its low absolute performance, the GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, ensuring modern API compatibility even if raw throughput is limited.

In Steamworld Build, the GPU's role is decisive. The game's city-building genre typically involves moderate polygon counts and limited particle effects, yet the data shows the Arc B370 struggles to maintain 60 FPS even at 1080p Low. The GPU's 20 ROPs become a bottleneck at higher resolutions, as the pixel fill rate of 48.00 GPixel/s cannot keep pace with the demands of 4K rendering.

How This Combo Ranks

The AMD Ryzen 7 5800X + Intel Arc B370 combination ranks 2683 out of 2924 tested combos in Steamworld Build, placing it in the bottom 8% of all configurations. This ranking reflects the GPU's significant performance limitations, as the CPU's capabilities are largely underutilized.

The combo's rank is consistent with the GPU's 5th percentile standing among all GPUs. The Arc B370's 3DMark Steel Nomad score of 1184 places it near the bottom of the performance spectrum, and this directly translates to poor in-game results. The CPU, by contrast, ranks at the 81st percentile among all CPUs with an average benchmark score of 29123, showing that the processor is not the limiting factor.

The delta between CPU and GPU performance tiers explains the combo's poor ranking. The Ryzen 7 5800X's nearest rivals in synthetic benchmarks — the Intel Core Ultra 5 135H (29093, 0.1% slower), Intel Xeon Phi 7210 (29245, 0.4% faster), and Intel Core i5-13500HX (29270, 0.5% faster) — all represent capable processors. However, the GPU's rivals — including the ATI Radeon HD 5770 from an older generation — highlight the Arc B370's dated performance level.

In practical terms, this ranking means the combo sits below the vast majority of tested systems for Steamworld Build. The game's genre typically benefits from strong single-threaded CPU performance for simulation logic, but the GPU bottleneck dominates in this configuration. Users seeking better frame rates would need to prioritize GPU upgrades before considering CPU changes.

CPU Role

The AMD Ryzen 7 5800X provides 8 cores and 16 threads based on the Zen 3 architecture, manufactured on TSMC's 7 nm process. It operates at a 3.80 GHz base clock and boosts to 4.70 GHz, with 32 MB of L3 cache and 512 KB of L2 cache per core. The CPU supports DDR4 memory with dual-channel configuration and 51.2 GB/s bandwidth.

The CPU's benchmark results show strong multi-threaded performance. Cinebench R23 scores reach 15476 multi-core and 1574.5 single-core, while Geekbench reports 11036 multi-core and 2032 single-core. PassMark multi-thread achieves 27732, with single-thread at 3445. The 3DMark tests show scaling from 943 single-thread to 7586 at 16 threads, indicating good thread scaling efficiency.

In Steamworld Build, the CPU's role appears secondary to the GPU. The game's city-building mechanics typically require substantial CPU resources for simulation, pathfinding, and population management. However, the measured FPS data shows that performance degrades predictably with resolution increases — a classic GPU-bound pattern. At 1080p Low, the system achieves 95 FPS, suggesting the CPU can feed the GPU adequately at lower resolutions.

The CPU's 81st percentile ranking and average benchmark score of 29123 indicate it is well above average for gaming workloads. Its nearest rivals in synthetic benchmarks — the Intel Core Ultra 5 135H (29093, 0.1% slower) and AMD Ryzen 5 5600XT (28940, 0.6% slower) — demonstrate that the 5800X remains competitive in its class. The CPU's 105 W TDP and AM4 socket compatibility suggest it is a mainstream desktop part, not a high-end enthusiast offering.

The data suggests that CPU performance is not the constraint in this configuration. Even at 1080p High, where the system achieves 55 FPS, the GPU is likely the limiting factor given its low benchmark scores. The CPU's 16 threads and high multi-threaded scores provide ample headroom for the game's simulation demands, but this headroom goes unused when the GPU cannot render frames quickly enough.

Measured FPS Breakdown

At 1920x1080, the resolution scaling shows a clear progression across settings. Low settings achieve 95 FPS average, Medium reaches 73 FPS with a minimum of 62 FPS and maximum of 84 FPS, High delivers 55 FPS, and Ultra drops to 37 FPS. The spread from Low to Ultra spans 58 FPS, with each settings tier costing approximately 20% performance.

The 2560x1440 results show a marked reduction across all settings. Low settings produce 61 FPS, Medium averages 46 FPS with a minimum of 39 FPS and maximum of 53 FPS, High reaches 35 FPS, and Ultra drops to 23 FPS. The Low to Ultra spread narrows to 38 FPS, indicating that the GPU becomes increasingly constrained as resolution rises.

At 3840x2160, the performance becomes marginal for all settings. Low settings achieve 32 FPS, Medium averages 25 FPS with a minimum of 21 FPS and maximum of 28 FPS, High reaches 18 FPS, and Ultra drops to 12 FPS. The Low to Ultra spread compresses to 20 FPS, suggesting that the GPU is operating at its ceiling even at the lowest settings.

The Medium settings data provides the most complete picture, with minimum and maximum values recorded at each resolution. At 1080p, the 62-84 FPS range shows reasonable consistency. At 1440p, the 39-53 FPS range indicates tighter frame pacing. At 4K, the 21-28 FPS range demonstrates severe performance degradation with limited variability.

The overall pattern reveals that this combination is only viable at 1080p, where it can maintain playable frame rates across all settings. At 1440p, Low settings are required for smooth gameplay, while 4K remains below playable thresholds regardless of configuration. The data confirms that the Intel Arc B370's limited fill rate and shading capabilities are the definitive constraint, with the Ryzen 7 5800X's strong CPU performance unable to compensate for the GPU's fundamental throughput limitations.
