Pc Building Simulator

# Pc Building Simulator — Intel Core i5-10400F + AMD Radeon RX 580

The measured frame rates for this combination in Pc Building Simulator show a system that is clearly GPU-limited at higher resolutions, but which becomes increasingly CPU-bound at 1080p. The Intel Core i5-10400F, a 6-core/12-thread Comet Lake part with a base clock of 2.90 GHz and boost of 4.30 GHz, pairs with the AMD Radeon RX 580, a Polaris 20 GPU with 8 GB of GDDR5 memory and a 256-bit bus. Across the twelve measured configurations, the average FPS ranges from 19.2 at 4K Ultra to 118 at 1080p Low, a span of nearly 100 frames that reveals how sensitive this title is to both resolution and preset selection.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent across all settings. At High preset, the system delivers 58.5 FPS at 1080p, falls to 37.4 FPS at 1440p, and reaches only 21.3 FPS at 4K — a 63.6% reduction from 1080p to 4K. The same pattern holds at Medium: 86.6 FPS at 1080p, 52.9 FPS at 1440p, and 26.8 FPS at 4K. Low preset shows the largest absolute drop, from 118 FPS at 1080p to 75.3 FPS at 1440p, then 40.7 FPS at 4K, a 65.5% decline overall.

This scaling behavior indicates that the RX 580 is the limiting component at 1440p and 4K. The pixel throughput required at 3840x2160 is four times that of 1920x1080, and the GPU's 256.0 GB/s memory bandwidth and 6.175 TFLOPS FP32 performance simply cannot sustain high frame rates at that resolution. At 1080p, however, the scaling is more moderate — the gap between 1080p and 1440p High is 21.1 FPS, while the gap between 1440p and 4K High is 16.1 FPS, suggesting the CPU begins to play a larger role at lower resolutions where the GPU is less stressed.

The data shows that 1080p is the only resolution where this combo approaches playable frame rates across all presets. At 1440p, only Low (75.3) and Medium (52.9) exceed 50 FPS, while High and Ultra fall to 37.4 and 35.7 respectively. At 4K, every preset falls below 41 FPS, with Ultra dipping to 19.2 — a figure that indicates the GPU is the bottleneck, as no CPU configuration could overcome the raw pixel demands at this resolution.

CPU Role

The Intel Core i5-10400F provides 6 cores and 12 threads, with a boost clock of 4.30 GHz. Its benchmark results show a strong single-threaded presence — a 3dmark single-thread score of 688, a Cinebench R23 single-core score of 1453, and a Geekbench single-core score of 1454. In a simulation title like Pc Building Simulator, which often involves physics calculations and system state updates, this single-thread performance is relevant.

In multi-threaded workloads, the CPU scores 10297 in Cinebench R23 multi-core, 4324 in Cinebench R20 multi-core, and 12115 in Passmark multi-thread. The 3dmark results show a scaling curve from 1350 (2 threads) to 3929 (8 threads) to 4735 (max threads), indicating that the CPU gains about 3.5x performance from 2 to 12 threads — decent scaling, but not perfect linearity, which is typical for a 6-core part with 12 threads.

Relative to its nearest rivals, this CPU sits in a tight cluster. Its average benchmark score of 14168 is 0.4% above the AMD EPYC 7552 (14115), 0.8% below the AMD Ryzen 3 7320C (14277), and 1.1% below the Intel Core i5-8500 (14332). This places the i5-10400F at the 73rd percentile among all CPUs, meaning it outperforms roughly three-quarters of tested processors, but it is not a top-tier part.

In the context of Pc Building Simulator, the CPU's role becomes evident at 1080p Low, where the RX 580 delivers 118 FPS. At this setting, the GPU is not heavily taxed, and the CPU's 4.30 GHz boost clock helps maintain frame pacing. However, at 4K Ultra (19.2 FPS), the CPU is clearly not the limiting factor — the GPU is overwhelmed, and no CPU-side improvement would meaningfully change the result.

How This Combo Ranks

This combination ranks 1649 out of 1769 tested combos in Pc Building Simulator, placing it in the bottom 6.8% of all configurations. This low ranking is notable given that both components individually sit near the middle of their respective distributions — the CPU at the 73rd percentile and the GPU at the 53rd percentile.

The ranking suggests that Pc Building Simulator is a demanding title, or that the RX 580, despite its 8 GB VRAM and 256-bit bus, is insufficient for this game at higher settings. The GPU's average benchmark score of 13559 is nearly identical to the NVIDIA GeForce GTX 570 (13564, delta 0%), and only 0.1% above the GTX 950 (13549). This means the RX 580 performs at roughly the level of a GTX 570, which is a much older card, despite having more VRAM.

The combo's 1649th rank out of 1769 is a direct consequence of the GPU's limited throughput. Even though the CPU is reasonably capable, the measured FPS at 1440p and 4K are too low to compete with combos featuring stronger GPUs. At 1080p, the system is more competitive — 118 FPS at Low and 86.6 at Medium are respectable — but the overall ranking is dragged down by the poor 4K performance, where all presets fail to reach 41 FPS.

GPU Role

The AMD Radeon RX 580 is built on the Polaris 20 chip using a 14 nm process, with 5,700 million transistors on a 232 mm² die. Its base clock is 1257 MHz, boosting to 1340 MHz, while the 8 GB of GDDR5 memory runs at 2000 MHz (8 Gbps effective) across a 256-bit bus, yielding 256.0 GB/s of bandwidth. The GPU features 2304 shading units, 144 TMUs, and 32 ROPs, with a pixel rate of 42.88 GPixel/s and a texture rate of 193.0 GTexel/s.

In Pc Building Simulator, the GPU's role is most apparent in the resolution scaling. At 1080p Low, the system hits 118 FPS, but this drops to 86.6 at Medium, 58.5 at High, and 59 at Ultra — note the near-identical High and Ultra results, suggesting the Ultra preset adds little beyond High for this GPU. At 1440p, the pattern shifts: Low produces 75.3 FPS, Medium 52.9, High 37.4, and Ultra 35.7. At 4K, the GPU is clearly overwhelmed: Low yields 40.7, Medium 26.8, High 21.3, and Ultra 19.2.

The GPU's benchmark scores reflect its mid-range status. Its Passmark G3D score is 8813, and its 3dmark Steel Nomad DX12 score is 1005. The Geekbench OpenCL score of 37453 and Vulkan score of 45173 indicate moderate compute capability. Relative to its nearest rivals, the RX 580's average score of 13559 is essentially tied with the GTX 570 (13564, 0% delta), 0.1% above the GTX 950 (13549), and 1.1% above the AMD Radeon Pro 455 (13416). This places the GPU at the 53rd percentile, slightly above average but not competitive with modern mid-range cards.

The GPU's 8 GB VRAM is not a limiting factor in this game at these settings, as the measured FPS drops are consistent with compute and bandwidth limits rather than memory capacity issues. However, the 256-bit bus and 256.0 GB/s bandwidth are insufficient for 4K, where the pixel fill rate demands exceed what the 42.88 GPixel/s pixel rate can deliver.

Settings Recommendations

The measured data provides a clear hierarchy of settings for each resolution. At 1080p, Medium (86.6 FPS) and High (58.5 FPS) both offer playable experiences, while Ultra (59 FPS) provides nearly identical performance to High — the 0.5 FPS difference is negligible. Low (118 FPS) is only necessary for high-refresh-rate displays, as it more than doubles the Ultra frame rate.

At 1440p, the choices are more constrained. Low (75.3 FPS) is the only preset that consistently exceeds 60 FPS, while Medium (52.9 FPS) is playable but not smooth. High (37.4) and Ultra (35.7) are both below 40 FPS, which is likely to feel stuttery in a simulation game. For a balanced experience at 1440p, Medium is the highest reasonable preset.

At 4K, no preset achieves playable frame rates. Low (40.7 FPS) is the best option, but even this is marginal. Medium (26.8), High (21.3), and Ultra (19.2) are all below 30 FPS, making them unsuitable for smooth gameplay. The data indicates that this combo should not be used at 4K for Pc Building Simulator, regardless of preset.

The most efficient configuration is 1080p High at 58.5 FPS, which provides a good balance of visual quality and performance. For users seeking higher frame rates, 1080p Medium (86.6 FPS) is the best option, as it delivers 48% more FPS than High while presumably retaining decent visual fidelity. At 1440p, Low (75.3 FPS) is the only preset that avoids significant frame pacing issues. The Ultra preset at any resolution offers no meaningful benefit over High — the 4K Ultra (19.2) and 4K High (21.3) are within 2 FPS of each other, suggesting that the Ultra settings do not tax the GPU in a way that justifies the performance cost.
