Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data for Pc Building Simulator reveals a steep and consistent performance cliff as resolution climbs. At 1080p Low, the combo posts 117.3 FPS, which drops to 75.1 FPS at 1440p Low and further to 39 FPS at 4K Low. That is a 36% decline from 1080p to 1440p, and a 48% decline from 1440p to 4K. The pattern is similar across all settings presets, but the relative drop becomes more punishing at higher quality levels. For High settings, the progression is 59.8 FPS at 1080p, 40 FPS at 1440p, and 19.1 FPS at 4K — a 33% drop from 1080p to 1440p, then a 52% drop from 1440p to 4K. Ultra settings show the same shape: 55.4 FPS at 1080p, 39 FPS at 1440p, and 18.5 FPS at 4K.

The data suggests the AMD Radeon RX 580 is the dominant bottleneck at higher resolutions. The GPU's 8 GB of GDDR5 memory on a 256-bit bus with 256.0 GB/s bandwidth is clearly being saturated as pixel count increases. The RX 580's boost clock of 1340 MHz and 2304 shading units simply cannot sustain frame rates at 4K, where even Low settings only manage 39 FPS. The fact that dropping from Ultra to Low at 4K only recovers about 20.5 FPS (from 18.5 to 39) indicates the GPU is fundamentally limited by its raw throughput rather than by specific settings overhead.

At 1080p, the picture is different. The jump from Low (117.3 FPS) to High (59.8 FPS) shows a much larger sensitivity to settings, suggesting that at lower resolutions the GPU has enough headroom that the quality preset becomes the primary variable. This is classic behavior for a system where the GPU is the limiting factor but is still capable at lower pixel counts. The Intel Core i5-14400F, with 10 cores and 16 threads boosting to 4.70 GHz, appears to have ample headroom in this simulation title, as the FPS scaling tracks resolution changes almost exactly with GPU load expectations.

The 4K Ultra result of 18.5 FPS is effectively unplayable, while 4K Low at 39 FPS is borderline. The data implies that for this game, the RX 580 is a 1080p-class card with some 1440p capability at reduced settings, but 4K is beyond its practical reach regardless of settings.

FAQ

Q: What is the best resolution for this combo in Pc Building Simulator?

A: The data shows 1920x1080 as the only resolution where the combo exceeds 60 FPS on any preset. Low settings hit 117.3 FPS, Medium reaches 86 FPS, and High achieves 59.8 FPS. At 1440p, only Low settings (75.1 FPS) clear 60 FPS.

A: At 2560x1440, the GPU manages 75.1 FPS on Low, 51.6 FPS on Medium, 40 FPS on High, and 39 FPS on Ultra. The drop from High to Ultra is minimal (1 FPS), suggesting Ultra's additional demands are not well-supported by the hardware.

Q: Is the CPU or GPU the limiting factor at 1080p?

A: Benchmark results indicate the GPU is the primary limiter even at 1080p. The i5-14400F has a strong multi-threaded score of 21914 in Cinebench R23, and the FPS scaling from Low to Ultra at 1080p (117.3 to 55.4) reflects GPU-bound performance rather than CPU limitation.

Q: Can this combo handle 4K gaming in Pc Building Simulator?

A: No. The highest 4K result is 39 FPS on Low settings, with High at 19.1 FPS, Medium at 28.9 FPS, and Ultra at 18.5 FPS. All 4K results are below 40 FPS, indicating the GPU lacks the throughput for playable 4K performance.

Q: What is the FPS difference between Low and Ultra at 1080p?

A: The gap is 61.9 FPS, from 117.3 FPS on Low to 55.4 FPS on Ultra. This represents a 53% reduction in frame rate when moving from the lowest to the highest quality preset at 1080p.

Q: How does the RX 580's benchmark percentile relate to its in-game performance?

A: The GPU sits at the 53rd percentile among all GPUs with an average benchmark score of 13559. Its nearest rival, the NVIDIA GeForce GTX 570, scores 13564 with a 0% delta. This middling position aligns with the measured FPS results, which show capable 1080p performance but severe degradation at higher resolutions.

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core i5-14400F brings 10 cores and 16 threads to this pairing, with a base clock of 2.50 GHz and a boost clock of 4.70 GHz. This Raptor Lake-R architecture chip, built on Intel's 10 nm process, has a 20 MB shared L3 cache and supports DDR4 and DDR5 memory. The CPU's benchmark scores paint a picture of a strong mid-range processor: a Cinebench R23 multi-core score of 21914 and a single-core score of 3093 place it at the 88th percentile among all CPUs. Its average benchmark score of 32508 is nearly identical to the Intel Core i7-12800H (32513, 0% delta) and the AMD Ryzen 5 PRO 7645 (32446, 0.2% delta).

In Pc Building Simulator, the CPU's role appears secondary to the GPU. The measured FPS data shows that at any given resolution, the difference between Low and Ultra settings is substantial — 61.9 FPS at 1080p, 36.1 FPS at 1440p, and 20.5 FPS at 4K. This settings sensitivity is characteristic of a GPU-limited scenario, where the CPU can feed frames faster than the GPU can render them. The i5-14400F's high single-thread performance (311 in Cinebench R15 single-core, 3093 in R23 single-core) likely prevents CPU bottlenecks in this simulation title, which may not fully utilize all 16 threads.

The CPU's PassMark multi-thread score of 25783 and physics score of 1594 suggest it can handle complex simulation calculations, but the game's frame rates are consistently tied to resolution and GPU settings rather than CPU workload. At 1080p Low, the combo achieves 117.3 FPS — this is likely near the CPU's practical frame delivery limit for this game, but the GPU still has headroom, as evidenced by the fact that Medium settings drop to 86 FPS and High to 59.8 FPS, following a GPU-bound scaling curve.

The processor's 65 W TDP and active production status indicate it is a modern, efficient part, but its 88th percentile standing among CPUs is far above the RX 580's 53rd percentile among GPUs. This disparity reinforces that the GPU is the constraining component in this combo for this game.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

1920x1080: The combo delivers its best results here. Low settings produce 117.3 FPS, Medium hits 86 FPS, High reaches 59.8 FPS, and Ultra drops to 55.4 FPS. The spread from Low to Ultra is 61.9 FPS. Notably, the gap between High and Ultra is only 4.4 FPS, suggesting Ultra's additional quality settings cost little extra performance at this resolution.

2560x1440: Performance drops significantly across the board. Low settings yield 75.1 FPS, Medium produces 51.6 FPS, High manages 40 FPS, and Ultra matches High at 39 FPS. The difference between High and Ultra is just 1 FPS, indicating the GPU is already saturated at this resolution. The drop from 1080p to 1440p is most pronounced on Low settings, where 117.3 FPS falls to 75.1 FPS — a 42.2 FPS reduction.

3840x2160: This is the weakest territory for the combo. Low settings achieve 39 FPS, Medium reaches 28.9 FPS, High drops to 19.1 FPS, and Ultra bottoms out at 18.5 FPS. The gap between High and Ultra remains minimal at 0.6 FPS. At 4K, even the most aggressive settings reduction cannot bring the frame rate to a playable level, with the best case (Low) still under 40 FPS.

The pattern across all resolutions is consistent: Low settings provide the highest headroom, Medium offers a balanced middle ground, and High and Ultra cluster together at the bottom. This clustering suggests the game's High and Ultra presets impose similar GPU loads, while Low and Medium are progressively lighter.

How This Combo Ranks — use comboRankInGame vs other tested combos

In the database of tested combos for Pc Building Simulator, this pairing of Intel Core i5-14400F and AMD Radeon RX 580 ranks 1653 out of 1769 total combinations. This places it in the bottom 7% of all tested configurations, which aligns with the measured FPS data showing sub-60 FPS performance on most settings at 1080p and above.

The rank is particularly telling given the CPU's strong standing. The i5-14400F sits at the 88th percentile among all CPUs, but the RX 580's 53rd percentile position drags the combo down. The GPU's average benchmark score of 13559 is nearly matched by the NVIDIA GeForce GTX 570 (13564, 0% delta) and the GTX 950 (13549, 0.1% delta), both of which are significantly older architectures. This indicates the RX 580 is the weak link in the pairing.

The rank of 1653 out of 1769 means most other combos tested in this game achieve higher frame rates. The data suggests that for Pc Building Simulator specifically, the RX 580's 8 GB of VRAM and 256.0 GB/s bandwidth are insufficient to push this title into higher performance tiers. The combo's low rank is consistent with the measured FPS results, which show the system struggling to maintain 60 FPS at 1080p on anything above Medium settings.

Comparatively, the CPU's nearest rivals — the Intel Core i7-12800H and AMD Ryzen 5 PRO 7645 — have near-identical average benchmark scores, but the overall combo rank would depend heavily on the GPU paired with them. In this configuration, the GPU clearly limits the system's potential.

Settings Recommendations — which preset gives the best experience per the measured rows

For 1080p, the data suggests Medium settings (86 FPS) offers the best balance of visual quality and performance. Low settings (117.3 FPS) provide maximum smoothness but sacrifice visual fidelity, while High (59.8 FPS) and Ultra (55.4 FPS) hover near the 60 FPS threshold. The 4.4 FPS difference between High and Ultra at 1080p means Ultra is a reasonable choice if visual quality is prioritized, as the performance cost is minimal.

At 1440p, Low settings (75.1 FPS) are the only preset that comfortably exceeds 60 FPS. Medium (51.6 FPS) is playable but not ideal, while High (40 FPS) and Ultra (39 FPS) fall below the smoothness threshold. The 1 FPS difference between High and Ultra at this resolution makes Ultra the better choice if the user insists on higher quality, since the performance penalty over High is negligible.

At 4K, no settings preset achieves playable frame rates. Low (39 FPS) is the only option that approaches 40 FPS, but the game will feel sluggish. Medium (28.9 FPS) and High/Ultra (19.1/18.5 FPS) are all below acceptable playability. The data indicates that 4K should be avoided entirely with this combo.

The overall recommendation is 1080p Medium for the best experience, or 1080p Ultra if visual fidelity matters more than the 30.6 FPS difference from Medium. At 1440p, users should stick to Low settings to maintain frame rates above 70 FPS.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 580 is a Polaris 20 chip built on GlobalFoundries' 14 nm process, with 5,700 million transistors on a 232 mm² die. It operates at a base clock of 1257 MHz and a boost clock of 1340 MHz, with 8 GB of GDDR5 memory running at 2000 MHz (8 Gbps effective) across a 256-bit bus, yielding 256.0 GB/s of bandwidth. The GPU has 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. Its FP32 performance is 6.175 TFLOPS.

The GPU's 53rd percentile standing among all GPUs, with an average benchmark score of 13559, places it in the middle of the pack. Its nearest rivals include the NVIDIA GeForce GTX 570 (13564, 0% delta) and GTX 950 (13549, 0.1% delta), which are similarly aged parts. The RX 580's DirectX 12 benchmark score of 43 and Vulkan score of 45173 in Geekbench suggest moderate modern API performance.

In Pc Building Simulator, the GPU's limitations are clear from the measured FPS data. The 8 GB VRAM is sufficient for this simulation title, but the 256.0 GB/s bandwidth becomes a constraint at higher resolutions. The 4K results, which max out at 39 FPS on Low settings, indicate the GPU's memory bandwidth and compute throughput cannot handle the pixel count. The 18.5 FPS at 4K Ultra is particularly telling — the GPU is completely overwhelmed.

The RX 580's 185 W TDP and suggested PSU of 450 W show it is a power-hungry part for its performance class. Its PCIe 3.0 x16 interface, while older, does not appear to be a bottleneck in this game based on the FPS scaling. The GPU's end-of-life production status and 2017 release date are consistent with its middling benchmark position.

The data shows that the RX 580's 6.175 TFLOPS of FP32 performance is simply not enough for 1440p Ultra or any 4K preset in this game. The GPU's 32 ROPs and 42.88 GPixel/s pixel rate become the limiting factor at 4K, where resolution demands overwhelm the rasterization throughput. For Pc Building Simulator, the RX 580 is best utilized at 1080p with Medium or Ultra settings, where it delivers 86 FPS and 55.4 FPS respectively.
