Pc Building Simulator

The AMD Radeon RX 580 paired with the Intel Core i7-14700KF produces a highly resolution-sensitive experience in Pc Building Simulator. The measured frame rates show a clear and steep degradation as pixel count increases, moving from a very playable 123.2 FPS at 1080p Low to a nearly unplayable 20 FPS at 4K High. This pattern indicates that the RX 580 is the definitive limiting component at higher resolutions, while the i7-14700KF's substantial processing power is largely underutilized.

Resolution Scaling

The performance drop from 1080p to 4K is dramatic and exposes the GPU's bandwidth and shading limitations. At 1080p Low, the system achieves 123.2 FPS, which drops to 77.6 FPS at 1440p Low—a reduction of 45.6 FPS (approximately 37%). Moving to 4K Low yields 39 FPS, which is less than one-third of the 1080p Low result. This scaling pattern is typical of a GPU that is saturated by pixel fill and memory bandwidth constraints, not a CPU-bound scenario.

The gap between Low and Ultra settings widens as resolution increases. At 1080p, the spread from Low (123.2 FPS) to Ultra (56.1 FPS) is 67.1 FPS. At 1440p, the spread shrinks to 43.3 FPS (from 77.6 to 34.3 FPS). At 4K, the spread narrows further to just 18 FPS (from 39 to 21 FPS). This convergence indicates that at 4K, the GPU is so heavily loaded that even reducing settings to Low cannot restore fluid performance—the chip's raw throughput becomes the hard ceiling.

The data shows that 1440p represents a borderline zone for this combination. At 1440p Medium, the system delivers 54.3 FPS, which is acceptable for a simulation title, but 1440p High drops to 38.3 FPS and 1440p Ultra to 34.3 FPS. The jump from 1440p to 4K is catastrophic: 4K Medium (28.1 FPS) and 4K High (20 FPS) both fall below the threshold for smooth interaction. Benchmark results indicate that the RX 580's 256-bit memory interface and 256.0 GB/s bandwidth are insufficient for 4K workloads, regardless of the i7-14700KF's ability to feed data quickly.

GPU Role

The AMD Radeon RX 580 is the primary bottleneck in this configuration, and its specifications confirm why. The GPU operates at a base clock of 1257 MHz and a boost clock of 1340 MHz, with 2304 shading units and 32 ROPs. Its 8 GB of GDDR5 memory on a 256-bit bus provides 256.0 GB/s of bandwidth. These figures place the RX 580 in the 53rd percentile among all GPUs, with an average benchmark score of 13559.

In Pc Building Simulator, the GPU's role is to render the system-building interface, component models, and live benchmarks within the simulation. The measured FPS at 1080p High (60.2 FPS) suggests the RX 580 can handle this workload at mainstream resolutions, but the 4K results (20-39 FPS across all settings) show that its 6.175 TFLOPS of FP32 compute is not enough for high pixel counts. The GPU's nearest rivals—the NVIDIA GeForce GTX 570 (avg score 13564) and GTX 950 (avg score 13549)—are within 0.1% performance, confirming the RX 580's position as a mid-range part from its era.

The VRAM capacity of 8 GB is not the limiting factor here, as Pc Building Simulator is not a texture-heavy title. Instead, the constraint is the memory bandwidth and the sheer number of pixels the ROPs must fill at 4K. The pixel rate of 42.88 GPixel/s and texture rate of 193.0 GTexel/s are modest by modern standards, and the 4K Ultra result of 21 FPS reflects these limits. The GPU's end-of-life production status and 14 nm process node further underscore its age relative to the CPU.

Settings Recommendations

The measured rows provide a clear hierarchy of playable settings. For a smooth experience, the data supports 1080p as the primary resolution for this GPU. At 1080p Medium, the system delivers 85.9 FPS, which is well above the 60 FPS target. Pushing to 1080p High yields 60.2 FPS, still acceptable, while 1080p Ultra falls to 56.1 FPS—borderline for a simulation where menu navigation and part placement require responsiveness.

At 1440p, the choices become more constrained. The only setting that maintains a comfortable frame rate is Low, at 77.6 FPS. Moving to Medium drops the average to 54.3 FPS, which may be tolerable for a slower-paced simulation but is not ideal. The data suggests that 1440p High (38.3 FPS) and Ultra (34.3 FPS) are not recommended, as they approach the stutter threshold where the interface feels sluggish.

For 4K, the results are uniformly poor. The best 4K result is Low at 39 FPS, which is still below 40 FPS and will feel choppy. Medium (28.1 FPS), High (20 FPS), and Ultra (21 FPS) are all effectively unplayable. The recommendation from the measured data is to avoid 4K entirely with this GPU. The optimal experience is 1080p Medium or High, where the system balances visual fidelity with frame rates above 60 FPS. If 1440p is necessary, Low settings are the only viable option.

How This Combo Ranks

This specific combination of the Intel Core i7-14700KF and AMD Radeon RX 580 ranks 1629 out of 1769 tested combos in Pc Building Simulator. This places it in the bottom 8% of all combinations, indicating a significant mismatch between the CPU and GPU capabilities. The rank reflects the overall system performance in this game, where the GPU's limitations drag down what would otherwise be a top-tier CPU.

The i7-14700KF is a high-end processor, ranked in the 96th percentile among all CPUs with an average benchmark score of 70104. Its nearest rivals include the Intel Core i7-14700K (deltaPct 0%), AMD EPYC 9115 (0.3%), and AMD Ryzen 9 9950X (-0.4%). In contrast, the RX 580 sits in the 53rd percentile among GPUs with an average score of 13559. The 1629th rank out of 1769 combos shows that the GPU's performance ceiling is the dominant factor in this pairing.

Benchmark results indicate that this combo would be severely CPU-bound at low resolutions and low settings, but GPU-bound at higher resolutions. At 1080p Low, the 123.2 FPS result is likely close to what the CPU can feed, but the GPU is still the limiting factor because the i7-14700KF's 20 cores and 28 threads are far more capable than the RX 580's throughput. The rank of 1629 suggests that most other tested combinations achieve better overall frame rates, likely because they pair more balanced components.

CPU Role

The Intel Core i7-14700KF plays a secondary role in this game's performance, but its specifications explain why it is not the bottleneck. This processor features 20 cores (a mix of performance and efficiency cores) and 28 threads, with a base clock of 3.40 GHz and a boost clock of 5.60 GHz. It has 33 MB of shared L3 cache and supports DDR4 and DDR5 memory on a dual-channel bus. The CPU's average benchmark score of 70104 places it in the 96th percentile of all CPUs, with strong results in Cinebench R23 (44557 multicore, 6290 singlecore) and Geekbench (19287 multicore, 2972 singlecore).

Pc Building Simulator is a simulation title that likely uses CPU resources for physics calculations, component compatibility checks, and system state updates. However, the measured FPS at 1080p Low (123.2 FPS) suggests that even this demanding simulation cannot fully utilize the i7-14700KF's capabilities. The CPU's 125 W TDP and unlocked multiplier indicate it is designed for heavy workloads, but the game's frame rates are clearly governed by the GPU.

The CPU's role becomes more apparent when comparing Low to Ultra settings at the same resolution. At 1080p, the jump from Low to Ultra reduces FPS from 123.2 to 56.1, a 54% drop that is entirely attributable to GPU load. The CPU maintains consistent performance across these settings, as evidenced by the fact that the frame rate scaling follows GPU workload patterns. The i7-14700KF's nearest rivals—the i7-14700K (0% delta) and Ryzen 9 9950X (-0.4% delta)—have similar average scores, confirming that this CPU is not a limiting factor in this combination. For this game, the CPU's 20 cores and high boost clock are more than sufficient; the RX 580's 14 nm Polaris architecture is what holds the system back.
