# Pc Building Simulator: AMD Ryzen 9 9950X3D + AMD Radeon RX 580

This combination pairs AMD's flagship 16-core Zen 5 processor with a last-generation Polaris GPU, creating a stark imbalance in Pc Building Simulator. The benchmark data shows a system where the CPU has enormous headroom while the graphics card becomes the definitive performance ceiling, particularly at higher resolutions and quality settings. The measured frame rates across the twelve test configurations reveal a component pairing that delivers playable results at 1080p but struggles to maintain smooth motion at 4K, with the RX 580's age and memory configuration proving decisive.

Resolution Scaling

The frame rate drop from 1080p to 4K is severe and consistent across all quality settings, indicating a GPU-bound scenario. At Low settings, the average frame rate falls from 121.3 FPS at 1920x1080 to 77.6 FPS at 2560x1440—a 36% reduction—and then to 40.3 FPS at 3840x2160, which is just 33% of the 1080p result. This scaling pattern is characteristic of a graphics card operating at its bandwidth and shading limits, rather than a CPU bottleneck.

The Ultra settings tell an even more restrictive story: 57.5 FPS at 1080p drops to 35.1 FPS at 1440p and plummets to 20.3 FPS at 4K. The gap between Low and Ultra at 4K is only 20 FPS (40.3 versus 20.3), whereas at 1080p the same settings spread yields 63.8 FPS (121.3 versus 57.5). This compression of performance at higher resolutions confirms that the RX 580's pixel throughput and memory bandwidth are the limiting factors, not the Ryzen 9 9950X3D's computational capabilities.

The Medium preset follows the same trajectory, with 85 FPS at 1080p, 53.5 FPS at 1440p, and 25.7 FPS at 4K. The resolution scaling factor from 1080p to 4K at Medium is roughly 3.3x, meaning the card loses over two-thirds of its performance when moving to four times the pixel count. Pc Building Simulator's simulation workloads do not appear to place unusual demands on the CPU at lower resolutions, as the frame rates scale almost entirely with GPU workload.

GPU Role

The AMD Radeon RX 580 is built on the Polaris 20 chip with GCN 4.0 architecture, fabricated on a 14 nm process at GlobalFoundries. Its 8 GB of GDDR5 memory on a 256-bit bus delivers 256.0 GB/s of bandwidth, which is a modest figure by modern standards but sufficient for this simulation title at lower settings. The card's base clock of 1257 MHz and boost clock of 1340 MHz are conservative, and the 2304 shading units operate at a peak FP32 throughput of 6.175 TFLOPS.

In Pc Building Simulator, the GPU's 32 ROPs and 144 TMUs appear to be the primary constraints at 4K, where the Ultra preset manages only 20.3 FPS. The card's pixel rate of 42.88 GPixel/s and texture rate of 193.0 GTexel/s are simply insufficient for high-resolution rendering with quality effects enabled. The memory clock of 2000 MHz (8 Gbps effective) provides the 256.0 GB/s bandwidth, but this becomes a bottleneck when the game needs to fetch large texture sets at 3840x2160.

The RX 580's benchmark percentile of 53 places it in the middle of all GPUs, with an average benchmark score of 13559. Its nearest rivals include the NVIDIA GeForce GTX 570 at 13564 (0% delta) and the GTX 950 at 13549 (0.1% delta), indicating that this card performs at a level comparable to older mid-range parts. The 8 GB VRAM is adequate for Pc Building Simulator's requirements, but the raw compute and fill-rate limitations show up clearly in the 4K results, where even Low settings cannot maintain 60 FPS.

CPU Role

The AMD Ryzen 9 9950X3D is a 16-core, 32-thread processor based on Zen 5 architecture (Granite Ridge), built on TSMC's 4 nm process. It features a base clock of 4.30 GHz and a boost clock of 5.70 GHz, with 128 MB of shared L3 cache. The CPU's benchmark scores are exceptional: Cinebench R23 multicore reaches 59712, while single-core hits 8430, and Geekbench multicore scores 22515. The 3DMark 16-thread test produces 16374, with max-thread scoring 17184.

In Pc Building Simulator, the CPU's role is almost entirely secondary. The benchmark data shows no scenario where frame rates are limited by processor performance—at 1080p Low, the system achieves 121.3 FPS, and the drop to 4K is entirely attributable to the GPU. The Ryzen 9 9950X3D's 16 cores and 32 threads, combined with its high boost clock, provide far more processing headroom than this simulation game requires. The processor's percentile rank of 96 against all CPUs places it in the top tier, with an average benchmark score of 71660.

The CPU's nearest rivals include the Intel Xeon Platinum 8270 (avg score 71056, 0.9% delta) and the AMD Ryzen 9 9950X (70420, 1.8% delta), showing that the 9950X3D leads its immediate competition. However, this performance advantage is irrelevant in Pc Building Simulator, where the GPU's capability dictates the final frame rates. The 170 W TDP and dual 70.6 mm² die size indicate a high-end part that is fundamentally overqualified for this workload.

How This Combo Ranks

This specific combination ranks 1626 out of 1769 tested combos in Pc Building Simulator, placing it in the bottom 8% of all configurations. The ranking reflects the severe bottleneck created by pairing a top-tier 2025 processor with a 2017-era graphics card. The combo's position is particularly striking given the CPU's 96th percentile performance, which suggests that the ranking is almost entirely determined by the GPU's limitations.

The data indicates that this pairing would be better served by a more balanced graphics solution, as the RX 580's percentile of 53 against all GPUs is dramatically lower than the CPU's standing. The benchmark results show that the combo's performance at 1080p Ultra (57.5 FPS) is barely above the 4K Low result (40.3 FPS) of the same settings, underscoring the GPU's inability to scale with resolution demands. The rank of 1626 places this system in the company of configurations that are likely GPU-bound at 1080p, which is consistent with the measured frame rates showing 121.3 FPS at Low but only 57.5 FPS at Ultra.

Measured FPS Breakdown

At 1920x1080, the system delivers its best results. Low settings produce 121.3 FPS average, which is smooth and responsive. Medium settings drop to 85 FPS, still well within playable territory. High settings yield 60.1 FPS, and Ultra settings fall to 57.5 FPS—the only 1080p preset that dips below 60 FPS. The spread between Low and Ultra at 1080p is 63.8 FPS, showing that settings have a substantial impact at this resolution.

Moving to 2560x1440, the frame rates decline noticeably. Low settings average 77.6 FPS, which remains playable. Medium settings produce 53.5 FPS, and High settings yield 40.5 FPS. Ultra settings drop to 35.1 FPS, which is approaching the threshold where simulation games feel sluggish. The 1440p results show a 42.5 FPS spread between Low and Ultra.

At 3840x2160, the system struggles across all settings. Low settings average 40.3 FPS, Medium drops to 25.7 FPS, and High manages only 22.8 FPS. Ultra settings bottom out at 20.3 FPS, which is borderline unplayable for a simulation title. The 4K spread between Low and Ultra is just 20 FPS, indicating that the GPU is saturated even at the lowest quality preset. The data shows that this combo is only suitable for 1080p gaming, with 1440p requiring reduced settings and 4K being impractical for smooth play.
