# Pc Building Simulator — AMD Ryzen 9 9900X + AMD Radeon RX 580

The AMD Ryzen 9 9900X paired with the AMD Radeon RX 580 produces a heavily GPU-limited experience in Pc Building Simulator, with the graphics card consistently capping frame rates across all tested resolutions. The combo ranks 1617th out of 1769 tested configurations, placing it in the bottom 9% of all combinations, which reflects the RX 580's age rather than any weakness in the 12-core Ryzen processor. At 1080p Low, the pairing achieves 120.2 FPS, but this drops to just 19.2 FPS at 4K High, demonstrating a performance curve that is almost entirely dictated by the Polaris GPU.

Resolution Scaling

The frame rate collapse from 1080p to 4K is severe and tells a clear story about where the bottleneck lives. Moving from 1920x1080 to 2560x1440 at High settings reduces the average from 60.9 FPS to 40.5 FPS, a 33.5% drop. Pushing further to 3840x2160 at High yields only 19.2 FPS, which is a 68.5% decline from the 1080p result. This scaling pattern is characteristic of a GPU that has exhausted its pixel throughput capabilities well before the CPU becomes relevant.

At Low settings, the same resolution progression shows 120.2 FPS at 1080p, 76.2 FPS at 1440p, and 41.8 FPS at 4K. The 4K Low result is only slightly better than the 1440p High result (41.8 vs 40.5 FPS), indicating that the RX 580's 256-bit memory bus and 256.0 GB/s bandwidth are the limiting factors at higher pixel counts, regardless of quality preset. The gap between 1080p Low and 4K Low is 78.4 FPS, which is a 65.2% reduction — a steeper drop than many modern GPUs would show, confirming the Polaris architecture's struggle with 4K workloads.

The data suggests that 4K gaming is not viable with this combination. Even at Low settings, 41.8 FPS falls below the smoothness threshold most players expect, and at Medium or above, the results (29.4 and 21.3 FPS) are borderline unplayable. The 1440p results are more promising but still show that the GPU is working near its limits, with Ultra settings at 1440p producing 36.2 FPS. The resolution scaling curve indicates that this combo is best suited for 1080p operation, where it can maintain playable frame rates across all settings.

GPU Role

The AMD Radeon RX 580 is the dominant performance limiter in this pairing. With 8 GB of GDDR5 memory on a 256-bit bus, the card delivers 256.0 GB/s of bandwidth, which proves insufficient for 4K textures and high-detail rendering in Pc Building Simulator. The GPU's base clock of 1257 MHz and boost clock of 1340 MHz are modest by modern standards, and the 14 nm Polaris 20 chip with 2304 shading units produces 6.175 TFLOPS of FP32 compute. These figures place the RX 580 at the 53rd percentile among all GPUs, with an average benchmark score of 13559.

The nearest rivals contextualize the RX 580's position: the NVIDIA GeForce GTX 570 scores 13564 (0% delta), the GTX 950 scores 13549 (0.1% delta), the AMD Radeon Pro 455 scores 13416 (1.1% delta), and the NVIDIA P106-090 scores 13716 (-1.1% delta). This means the RX 580 is effectively in a dead heat with a decade-old GTX 570 in raw compute terms, though the RX 580's 8 GB VRAM gives it an advantage in texture-heavy scenarios. The 42.88 GPixel/s pixel rate and 193.0 GTexel/s texture rate are the figures that matter for this simulation game, and they explain why 4K High settings crush the card to 19.2 FPS.

The 8 GB VRAM capacity is not the primary constraint here — even at 4K Ultra, the card achieves 21.3 FPS, suggesting the core compute and memory bandwidth are the bottlenecks rather than frame buffer exhaustion. The GDDR5 memory running at 2000 MHz (8 Gbps effective) is outdated, and the 256-bit bus width cannot compensate for the low clock speed compared to modern GDDR6X or HBM solutions.

Settings Recommendations

The measured FPS rows provide a clear hierarchy of playable configurations. At 1920x1080, all four settings presets are technically playable, but the differences are stark. Low settings deliver 120.2 FPS, Medium delivers 88.1 FPS, High delivers 60.9 FPS, and Ultra drops to 58.5 FPS. The jump from High to Ultra costs only 2.4 FPS, which suggests that Ultra at 1080p is nearly as efficient as High — a rare case where the highest preset is worth the negligible performance penalty.

At 2560x1440, the picture changes. Medium settings produce 56.8 FPS, which is still smooth, while High drops to 40.5 FPS and Ultra falls to 36.2 FPS. The 1440p Low result of 76.2 FPS shows headroom, but the quality difference between Low and Medium is substantial in a simulation game where reading component details matters. For 1440p, Medium is the optimal choice because it maintains a frame rate above 55 FPS while offering noticeably better visuals than Low.

At 3840x2160, no settings preset achieves a playable frame rate. The best result is 41.8 FPS at Low, which is marginal, and Medium drops to 29.4 FPS. The recommendation is to avoid 4K entirely with this combo, or if forced, use Low settings and accept the 41.8 FPS average. The data shows that High settings at 4K produce 19.2 FPS, which is a slideshow, and Ultra is only marginally better at 21.3 FPS. The optimal experience is clearly 1080p Ultra at 58.5 FPS, which offers the best balance of visual fidelity and performance.

How This Combo Ranks

The combination of AMD Ryzen 9 9900X and AMD Radeon RX 580 ranks 1617th out of 1769 tested combos in Pc Building Simulator. This places it in the 9th percentile, meaning 91% of all tested CPU-GPU pairings outperform it in this game. The ranking reflects the GPU's severe limitation — the Ryzen 9 9900X is a top-tier processor that ranks in the 94th percentile among all CPUs, but it is paired with a GPU that sits in the 53rd percentile. The mismatch is enormous, and the combo ranking suffers accordingly.

The CPU's nearest rivals show how much headroom is being wasted. The AMD Ryzen 9 9900X3D scores 54681 (a -0.4% delta from the 9900X's 54450 average), while the Intel Core i7-14700F scores 54097 (0.7% delta), the Intel Core Ultra 5 245K scores 55304 (-1.5% delta), and the Intel Core Ultra 5 245KF scores 55421 (-1.8% delta). These processors are all within 2% of each other in CPU benchmarks, yet the combo ranking is dragged down entirely by the RX 580's 13559 average benchmark score, which sits at the 53rd percentile.

For context, the GPU's nearest rivals — the GTX 570, GTX 950, Radeon Pro 455, and P106-090 — all score within 1.1% of the RX 580. This means the combo's 1617th rank is not a result of a poorly matched CPU, but rather a GPU that is fundamentally outclassed in a modern simulation title. The Ryzen 9 9900X has 12 cores, 24 threads, and a boost clock of 5.60 GHz, but none of that matters when the GPU cannot deliver more than 120 FPS even at 1080p Low.

CPU Role

The AMD Ryzen 9 9900X is massively overqualified for this pairing. With 12 cores, 24 threads, a base clock of 4.40 GHz, and a boost clock of 5.60 GHz, this Zen 5 processor (Granite Ridge codename) delivers exceptional compute performance. Its Cinebench R23 multi-core score of 46438 and single-core score of 6555 place it among the fastest desktop CPUs available, and its 94th percentile ranking among all CPUs confirms this. The 64 MB of shared L3 cache and 89.6 GB/s of dual-channel DDR5 memory bandwidth provide ample data throughput for any game.

In Pc Building Simulator, the CPU's role is largely irrelevant because the RX 580 becomes the bottleneck at every resolution and settings combination. The evidence is in the FPS scaling: at 1080p Low, the combo reaches 120.2 FPS, but the CPU is capable of far higher frame rates in CPU-bound scenarios. The GPU's PassMark G3D score of 8813 and DirectX 12 score of 43 indicate that it cannot keep up with the CPU's ability to feed it draw calls. The Ryzen 9 9900X's single-thread performance (3DMark single-thread score of 1286, Geekbench single-core of 3341) would be sufficient for even the most demanding simulation logic, but the GPU's 6.175 TFLOPS of FP32 compute is the ceiling.

The CPU's nearest rivals all score within 1.8% of the 9900X, which means swapping to any of them would not change the game's performance at all — the RX 580 is the limiting factor in every case. The 9900X's 4 nm TSMC process and 16,630 million transistors are wasted on this workload, as the game's engine does not require the multi-threading capabilities that the 12-core processor offers. In CPU-bound titles, the 9900X would shine, but in this simulation game with this GPU, it is dormant.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best results. Low settings produce 120.2 FPS, Medium drops to 88.1 FPS, High falls to 60.9 FPS, and Ultra is nearly identical at 58.5 FPS. The 1080p Ultra result is notable because it is only 2.4 FPS below High, suggesting the Ultra preset adds minimal overhead in this game. The spread from Low to Ultra is 61.7 FPS, which is a 51.3% reduction.

At 2560x1440, the performance drops significantly. Low yields 76.2 FPS, Medium 56.8 FPS, High 40.5 FPS, and Ultra 36.2 FPS. The 1440p Medium result of 56.8 FPS is the last "smooth" threshold before the GPU starts to struggle. The drop from 1080p Medium to 1440p Medium is 31.3 FPS, a 35.5% decrease that highlights the GPU's resolution sensitivity.

At 3840x2160, the results are consistently poor. Low reaches 41.8 FPS, Medium 29.4 FPS, High 19.2 FPS, and Ultra 21.3 FPS. The Ultra result being higher than High is an anomaly in the test data, but both are unplayable. The 4K Low result of 41.8 FPS is the only one above 30 FPS, and even that is marginal. The total range across all 12 measurements spans from 19.2 FPS (4K High) to 120.2 FPS (1080p Low), a 101 FPS spread that demonstrates the extreme sensitivity of this combo to both resolution and settings.
