Pc Building Simulator

Pc Building Simulator is a simulation title that is far more demanding on the GPU than the CPU, and the data for the AMD Ryzen 7 5800XT + AMD Radeon RX 570 combination demonstrates a clear bottleneck. The measured frame rates show that the RX 570 is the limiting component at every resolution, with the powerful Ryzen 7 5800XT providing ample headroom that goes unused. The performance curve across resolutions confirms that this is a GPU-bound scenario, where visual fidelity and pixel count dictate the experience far more than the processor's capabilities.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep and consistent, pointing directly to the GPU as the performance ceiling. At 1080p High settings, the combo produces 56 FPS, but moving to 1440p High drops the average to 32.4 FPS, a reduction of 23.6 FPS. Pushing further to 4K High yields just 16.9 FPS, which is only 30% of the 1080p performance. This scaling pattern is classic GPU-bound behavior; the CPU is not struggling to feed the GPU, but rather the RX 570's compute and memory bandwidth are being saturated by the increasing pixel load.

The scaling is even more revealing at lower settings. With Low settings, the combo achieves 110.1 FPS at 1080p, but this falls to 70.9 FPS at 1440p and then to 37.7 FPS at 4K. The percentage drop from 1080p to 4K at Low settings is 65.8%, which is nearly identical to the 69.8% drop observed at High settings. This consistency suggests that the GPU's raw throughput, not the settings' specific effects, is the primary driver of performance degradation. If the CPU were the bottleneck, we would expect the Low settings to show a smaller relative drop, as the lower load would allow the CPU to maintain higher frames for longer. Instead, the data indicates that the RX 570's 224.0 GB/s memory bandwidth and 5.095 TFLOPS of FP32 compute are simply overwhelmed by the pixel count at 4K.

At 1440p, the story remains the same. The Ultra preset produces 32.4 FPS, which is identical to the High preset's 32.4 FPS. This plateau suggests that the GPU is already at its limit at this resolution, and further increasing settings from High to Ultra does not change the outcome because the bottleneck is the GPU's fill rate and shading power. The 4K Ultra result of 19.6 FPS is only 2.7 FPS higher than the 4K High result, reinforcing that the GPU is completely saturated and cannot be pushed further without a significant frame rate penalty.

How This Combo Ranks

The benchmark database ranks this pairing at 1658 out of 1769 tested combos for Pc Building Simulator, placing it in the bottom 6% of all tested configurations. This low rank is a direct consequence of the RX 570's age and performance tier, not the CPU. The Ryzen 7 5800XT is a high-end processor with an 86th percentile ranking among all CPUs, while the RX 570 sits at the 74th percentile among all GPUs. The combination of a top-tier CPU with a mid-range, end-of-life GPU creates a significant imbalance that the game's engine cannot exploit.

The nearest rival data for the GPU illustrates the competitive landscape. The RX 570's average benchmark score of 30158 is within 0.8% of the NVIDIA GeForce RTX 5070 Mobile and within 0.2% of the NVIDIA GeForce RTX 5060 and AMD Radeon RX 7700 XT. However, these deltaPct values are minimal, meaning the RX 570 is at the very bottom of this performance cluster. The fact that such modern GPUs are only slightly ahead in synthetic benchmarks does not translate to real-world gaming, where the RX 570's 4 GB VRAM and older GCN 4.0 architecture limit its effectiveness in a 2019 simulation title. The combo rank of 1658 out of 1769 indicates that most other pairings, even those with weaker CPUs, achieve better frame rates in this specific game because they are paired with more capable graphics cards.

Measured FPS Breakdown

The measured FPS data provides a full picture of the combo's capabilities across three resolutions and four settings presets. At 1920x1080, the average frame rates are 110.1 FPS for Low, 76.5 FPS for Medium, 56 FPS for High, and 53.1 FPS for Ultra. The jump from Low to Medium is 33.6 FPS, while the jump from Medium to High is 20.5 FPS, and from High to Ultra is only 2.9 FPS. This indicates diminishing returns as settings increase, with the GPU struggling to maintain the same relative performance gains at higher presets.

At 2560x1440, the averages are 70.9 FPS for Low, 50.9 FPS for Medium, 32.4 FPS for High, and 32.4 FPS for Ultra. The drop from Low to Medium is 20 FPS, but the drop from Medium to High is 18.5 FPS, and there is no change from High to Ultra. This plateau at 32.4 FPS confirms that the GPU is at its limit, unable to differentiate between High and Ultra workloads. At 3840x2160, the averages are 37.7 FPS for Low, 23.4 FPS for Medium, 16.9 FPS for High, and 19.6 FPS for Ultra. The Ultra setting is actually 2.7 FPS higher than High, which is likely a measurement anomaly but still indicates that all 4K presets are below the playable threshold of 30 FPS, except for Low which barely exceeds it.

GPU Role

The AMD Radeon RX 570 is the primary determinant of performance in this game. Its 4 GB of GDDR5 memory, running at 1750 MHz with a 256-bit bus, provides 224.0 GB/s of bandwidth. This memory configuration is insufficient for 4K textures, as evidenced by the sub-20 FPS results at 4K High and Ultra. The GPU's base clock of 1168 MHz and boost clock of 1244 MHz, combined with 2048 shading units, yields a texture rate of 159.2 GTexel/s and a pixel rate of 39.81 GPixel/s. These figures are modest by modern standards, and the game's simulation of PC building, which renders detailed 3D models and environments, taxes the GPU's fill rate heavily.

The GPU's benchmark scores further contextualize its position. Its Geekbench OpenCL score of 32084 and Vulkan score of 42752 show it can handle compute tasks, but its 3DMark Steel Nomad DX12 score of just 880 is indicative of its limited DirectX 12 performance. The GPU's percentile rank of 74 places it above average, but its nearest rivals are all modern cards, highlighting its age. The RX 570's end-of-life production status and lack of ray tracing cores or tensor cores mean it relies entirely on traditional rasterization, which is still the core requirement for Pc Building Simulator. The 150 W TDP and 450 W suggested PSU are modest, but the performance ceiling is the key issue, not power delivery.

CPU Role

The AMD Ryzen 7 5800XT plays a secondary role in this game, as its performance is far above what the RX 570 can utilize. The CPU's 8 cores and 16 threads, based on the Zen 3 architecture, provide substantial processing power. Its base clock of 3.80 GHz and boost clock of 4.80 GHz are high, and its 3DMark multi-threaded scores of 7683 (16 threads) and 6141 (8 threads) demonstrate strong multi-core capability. In Cinebench R23, it scores 23794 multi-core and 3359 single-core, indicating it can handle any simulation logic without breaking a sweat.

The CPU's percentile rank of 86 places it in the top 14% of all processors, and its average benchmark score of 29774 is nearly identical to its nearest rivals, including the AMD Ryzen 7 6800HS and AMD Ryzen 7 7840H, with deltaPct values of -0.3%. This means the 5800XT is statistically tied with those mobile parts in synthetic benchmarks, but its desktop platform with DDR4 memory support and PCIe Gen 4 provides a solid foundation. However, in Pc Building Simulator, the CPU's 32 MB of L3 cache and 51.2 GB/s memory bandwidth are not stressed, as the game's frame rates are dictated by the GPU. The data shows no scenario where the CPU becomes the bottleneck; even at 1080p Low with 110.1 FPS, the CPU has headroom, as the frame rate is still limited by the GPU's ability to render frames.

Settings Recommendations

For the best playable experience, the data suggests using 1080p with Medium settings, which yields 76.5 FPS, or High settings at 56 FPS. Both are above the 60 FPS and 30 FPS thresholds, respectively. The Ultra preset at 1080p produces 53.1 FPS, which is only 2.9 FPS lower than High, so the visual upgrade may be worth the minor frame rate cost. However, if a higher frame rate is preferred, Low settings at 1080p deliver 110.1 FPS, which is more than double the High settings result and provides the smoothest experience.

At 1440p, the options are more limited. Low settings at 70.9 FPS are playable, and Medium at 50.9 FPS is acceptable, but High and Ultra both cap at 32.4 FPS, which is below the 60 FPS ideal. For a balanced experience, 1440p Medium is the best choice, offering a 50.9 FPS average that is closer to playable while maintaining moderate visual quality. At 4K, only Low settings at 37.7 FPS are marginally playable, while Medium, High, and Ultra all fall below 25 FPS, making them unsuitable for smooth gameplay. The data strongly indicates that this combo is best suited for 1080p gaming, where it can achieve high frame rates on Medium or High presets, while 1440p and 4K should be avoided unless the user is willing to accept significant compromises in settings or frame rates.
