Steamworld Build

How This Combo Ranks

The Intel Core i5-12400 paired with the NVIDIA GeForce RTX 5080 lands at rank 90 out of 1730 tested combinations in Steamworld Build. That places this pairing in the top 5.2% of all tested combos, a strong result for a city builder where simulation logic and rendering overlap. The combo's percentile ranking reflects a system that can drive high refresh rates at mainstream resolutions while still maintaining playable frames at 4K Ultra. The ranking is notably high given that the CPU sits at the 77th percentile among all processors, while the GPU reaches the 89th percentile among all graphics cards. This suggests the pairing extracts near-maximum potential from both components, with neither acting as a severe bottleneck in this specific title. The data indicates that users with this combination should expect a fluid experience across the board, though the gap between the 90th rank and the top tier suggests there are faster configurations available, primarily those built around higher-end CPUs.

GPU Role

The RTX 5080 carries 16 GB of GDDR7 memory on a 256-bit bus, yielding 960.0 GB/s of bandwidth. Its Blackwell 2.0 architecture, built on a 5 nm process at TSMC, contains 10752 shading units, 336 texture mapping units, and 112 raster output pipelines. The GPU operates at a base clock of 2295 MHz with a boost clock of 2617 MHz, while memory runs at 1875 MHz with 30 Gbps effective speed. In Steamworld Build, the GPU's role shifts dramatically based on settings and resolution. At 1080p Low, the card delivers 307.5 FPS, indicating that the GPU is far from saturated and that the CPU is doing the heavy lifting. However, at 4K Ultra, performance drops to 52.6 FPS, showing that the GPU becomes the primary constraint when pixel count and visual effects stack up. The card's FP32 compute of 56.28 TFLOPS and pixel rate of 293.1 GPixel/s provide ample headroom for the game's isometric rendering and building animations. The RTX 5080's 84 RT cores and 336 tensor cores are underutilized in this title, as Steamworld Build does not heavily rely on ray tracing or AI-accelerated features. The GPU's PassMark G3D score of 36565 and average benchmark score of 59188 place it at the 89th percentile, with nearest rivals including the Intel Arc A570M (1.6% slower) and Intel Arc Pro A60 (1.9% faster), showing that the 5080 sits in a competitive performance envelope at its price tier.

CPU Role

The Intel Core i5-12400 is a 6-core, 12-thread processor from the Alder Lake-S family, with a base clock of 2.50 GHz and boost clock of 4.40 GHz. It features 18 MB of shared L3 cache and 1.25 MB L2 cache per core, with an 80 KB L1 cache per core. The CPU supports DDR4 and DDR5 memory in dual-channel configuration and connects via PCIe Gen 5 with 16 lanes. Its Cinebench R23 multi-core score of 15935 and single-core score of 2249 demonstrate solid multi-threaded throughput for simulation-heavy gameplay. In Steamworld Build, the CPU's role is most evident at lower resolutions and settings. At 1080p Low, the combo hits 307.5 FPS, which is likely near the engine's practical limit. The CPU's PassMark multi-thread score of 18747 and single-thread score of 3456 indicate that the six physical cores handle the game's simulation tick rate effectively, while the 12 threads allow background tasks to run without interfering with frame pacing. The i5-12400's nearest rivals in average benchmark score include the Intel Core i7-9700 (0.1% faster), Intel Core i7-8700 (0.2% slower), and Intel Core i5-11600K (0.4% slower), showing that this chip holds its own against older and similarly positioned parts. The CPU's 65 W TDP and active production status make it a power-efficient choice for sustained gaming sessions, though the unlocked multiplier is not available for overclocking headroom.

Measured FPS Breakdown

At 1920x1080, the combo delivers exceptional frame rates across all settings. Low settings produce 307.5 FPS, Medium yields 281 FPS, High reaches 241 FPS, and Ultra drops to 164.9 FPS. The scaling from Low to Ultra at 1080p shows a 46.4% reduction in frame rate, indicating that visual effects have a substantial impact even at this resolution. The gap between High and Ultra is particularly notable at 76.1 FPS, suggesting that Ultra settings enable effects that tax the GPU significantly.

Moving to 2560x1440, the performance remains strong. Low settings hit 262.1 FPS, Medium achieves 202.5 FPS, High reaches 151.5 FPS, and Ultra falls to 104.6 FPS. From 1080p to 1440p, the frame rate drops by 14.8% at Low, 27.9% at Medium, 37.1% at High, and 36.6% at Ultra. The larger percentage drops at higher settings indicate that the GPU is becoming more involved as resolution and visual complexity increase.

At 3840x2160, the picture changes significantly. Low settings produce 139 FPS, Medium delivers 110.9 FPS, High achieves 80.8 FPS, and Ultra drops to 52.6 FPS. The 4K results show a clear GPU bottleneck, particularly at Ultra, where the frame rate falls below the 60 FPS threshold. From 1440p to 4K, the drops are 47.0% at Low, 45.2% at Medium, 46.7% at High, and 49.7% at Ultra. These nearly uniform percentage reductions suggest that the GPU is now the limiting factor across all settings, with the CPU having ample headroom to feed frames.

Resolution Scaling

The resolution scaling data reveals a clear shift in the limiting component. From 1080p to 1440p, the average frame rate drop across all settings is approximately 28.6%, while from 1440p to 4K, the average drop is approximately 47.2%. This non-linear scaling indicates that the system moves from a CPU-bound state at low resolutions to a GPU-bound state at 4K. At 1080p, the CPU's 6 cores and 12 threads are sufficient to push frame rates beyond 300 FPS at Low settings, meaning the GPU is idling. As resolution increases, the GPU's workload grows, and by 4K, the RTX 5080's rendering capabilities become the primary constraint.

The transition is most dramatic at Ultra settings. At 1080p Ultra, the combo delivers 164.9 FPS, which is still highly playable. At 1440p Ultra, it drops to 104.6 FPS, a 36.6% reduction. At 4K Ultra, it falls to 52.6 FPS, a 49.7% reduction from 1440p. This pattern shows that while the GPU can handle 4K at lower settings (139 FPS at Low), the Ultra preset's additional effects—likely including enhanced shadows, ambient occlusion, and particle effects—push the card beyond its comfort zone. For users targeting 4K, the data suggests that High settings (80.8 FPS) provide a better balance than Ultra, while those at 1080p or 1440p can comfortably run Ultra settings. The CPU's role as the limiting factor at lower resolutions is further confirmed by the minimal frame rate differences between 1080p and 1440p at Low settings (307.5 vs 262.1 FPS), where the GPU has plenty of spare capacity and the CPU's single-thread performance becomes the bottleneck.
