Pc Building Simulator

Pc Building Simulator presents an unusual load profile where the AMD Ryzen 7 5800XT and AMD Radeon RX 6700 XT combination shows massive performance headroom at lower resolutions, with the GPU becoming the clear limiting factor only as pixel count climbs. The data shows a system that is overwhelmingly CPU-bound at 1080p, transitioning to a more balanced state at 1440p, and finally becoming GPU-bound at 4K, with the measured FPS drops across setting tiers revealing the architecture of this simulation title.

Resolution Scaling

The frame rate scaling from 1080p to 4K exposes a stark contrast in workload characteristics. At Low settings, the system delivers 272.1 FPS at 1920x1080, but this collapses to 172.5 FPS at 2560x1440 (a 36.6% drop) and further to 87.1 FPS at 3840x2160 (a 68% drop from the 1080p baseline). This steep decline indicates that even at Low settings, the GPU is being pushed harder as resolution increases, though the absolute numbers suggest the CPU is still feeding frames efficiently at 1440p.

The Medium settings row tells a similar story: 192.4 FPS at 1080p, 119.4 FPS at 1440p, and 62.8 FPS at 4K. The transition from 1080p to 1440p costs 73 FPS, while the jump to 4K costs another 56.6 FPS. This pattern of diminishing returns as resolution increases is typical of a GPU that has ample headroom at lower resolutions but becomes saturated at 4K, particularly when the simulation's logic and rendering demands scale with pixel count.

High settings show 137.2 FPS at 1080p, 82.4 FPS at 1440p, and 41.6 FPS at 4K. The 4K result is particularly telling — it falls below the 60 FPS threshold that many users target, indicating that this combo is not ideal for 4K High gaming in this title. Ultra settings mirror this trend with 128.9 FPS, 79.8 FPS, and 42.3 FPS respectively. The difference between High and Ultra at 4K is minimal (0.7 FPS), suggesting that the Ultra preset's additional effects are not the bottleneck at that resolution — the raw pixel throughput is.

The data indicates that 1440p is the sweet spot where the CPU and GPU balance each other. At 1080p, the system is clearly CPU-limited, as the GPU could likely render more frames than the CPU can request. At 4K, the GPU becomes the limiting component, and the CPU's headroom is irrelevant. The scaling from 1080p to 1440p at Low settings (99.6 FPS drop) versus the scaling from 1440p to 4K at Low settings (85.4 FPS drop) shows that the GPU's workload per pixel is the dominant factor at higher resolutions.

Settings Recommendations

The measured data shows that Medium settings at 1440p offers the best balance of visual fidelity and performance, delivering 119.4 FPS. This is significantly above the 60 FPS threshold and only 53.1 FPS below the Low setting at the same resolution, while providing substantially better visuals than Low. For users with 1440p displays, this is the recommended preset based purely on the FPS data.

At 1080p, High settings at 137.2 FPS is the strongest recommendation. It offers 55.2 FPS more than Ultra at the same resolution while being visually close in most scenes. The jump from High to Ultra at 1080p costs only 8.3 FPS, which is relatively minor, but the Medium preset at 192.4 FPS is overkill for most displays. The data suggests that High is the efficiency sweet spot at 1080p, providing smooth gameplay without the unnecessary performance expenditure of Medium.

For 4K, the data shows that Low settings at 87.1 FPS is the only preset that maintains comfortable playability. Medium at 62.8 FPS is technically above 60 FPS but leaves little margin for scene complexity spikes. High at 41.6 FPS and Ultra at 42.3 FPS are both below 60 FPS, making them less suitable for consistent performance. The minimal difference between High and Ultra at 4K (0.7 FPS) suggests that the Ultra preset's extra effects are not the primary cost at this resolution — the pixel count is.

The overall recommendation across all resolutions is to prioritize Medium or High settings. Low settings provide high FPS but sacrifice the simulation's visual feedback, which is important for a game about building and inspecting PCs. Medium settings at 1440p provides the best overall experience, balancing the 119.4 FPS measured result with adequate visual detail. For users with 1080p monitors, High at 137.2 FPS is the clear winner, as it provides smooth performance and good visuals without the diminishing returns of Ultra.

GPU Role

The AMD Radeon RX 6700 XT features 12 GB of GDDR6 memory on a 192-bit bus, with a bandwidth of 384.0 GB/s. The GPU's clocks are notably high, with a base clock of 2321 MHz, a game clock of 2424 MHz, and a boost clock of 2581 MHz. These specifications are directly relevant to the measured results, as the high boost clock helps maintain frame rates when the GPU is the limiting factor at 4K.

The GPU's 2560 shading units and 64 ROPs are sufficient for this simulation title, which does not appear to be heavily geometry-bound based on the FPS scaling. The 12 GB VRAM is adequate for the measured settings, as none of the results show stuttering or frame drops that would indicate memory capacity issues. The 384.0 GB/s bandwidth is likely sufficient for the texture loads in this game, as the performance degradation from 1440p to 4K is consistent with pixel count scaling rather than memory bandwidth saturation.

The RX 6700 XT's performance in this game places it in the 77th percentile of all GPUs, with an average benchmark score of 33721. Its nearest rivals include the AMD Radeon RX 6800 with a deltaPct of 0.7% and the NVIDIA RTX A5000 at 1.3% faster. These close margins indicate that the RX 6700 XT is positioned in a competitive performance tier, and the measured FPS results reflect this mid-to-high-end positioning. The GPU's RDNA 2.0 architecture with 40 RT cores is present in the hardware, though the measured data does not show ray tracing-specific metrics for this title.

The GPU's role in this combo becomes clear when examining the 4K results. At High settings, the 41.6 FPS result is well below what the CPU could theoretically support, indicating that the GPU is the sole bottleneck. The 12 GB VRAM and 384.0 GB/s bandwidth are not limiting factors at these settings, as the frame rate is more constrained by the shading and ROP throughput. The boost clock of 2581 MHz is the key differentiator, as the GPU is likely sustaining high clocks under this load.

How This Combo Ranks

The AMD Ryzen 7 5800XT and AMD Radeon RX 6700 XT combination ranks 968 out of 1769 tested combos in Pc Building Simulator. This places it in the 45.3rd percentile of all tested combinations, meaning roughly 45% of combos perform better and 55% perform worse. This mid-pack ranking is consistent with the measured FPS data, which shows strong 1080p performance but weaker 4K results.

The ranking reflects the balance between the CPU and GPU. The Ryzen 7 5800XT is a high-end CPU with an 86th percentile ranking among all CPUs, while the RX 6700 XT sits at the 77th percentile among GPUs. The combination of a stronger CPU with a mid-to-high-end GPU creates a system that excels at CPU-bound scenarios (1080p) but falls behind in GPU-bound scenarios (4K). This is reflected in the 968th rank, which is lower than the individual component percentiles might suggest.

The combo's rank is influenced by the fact that Pc Building Simulator is a simulation title that likely has significant CPU overhead for game logic, but the measured FPS at 4K shows that the GPU becomes the limiting factor. The 968th rank suggests that there are many combos with better GPU performance that achieve higher 4K frame rates, even if their CPUs are weaker. Conversely, the strong 1080p results (272.1 FPS at Low) show that this combo outperforms many others in CPU-bound scenarios.

The deltaPct values for the CPU's nearest rivals are tight, with the AMD Ryzen 7 PRO 5755GE at 0.1% faster and the AMD Ryzen 7 6800HS at 0.3% slower. This indicates that the CPU is well-matched to its peers, and the combo's rank is more heavily influenced by the GPU's performance tier than the CPU's. The GPU's nearest rivals show a wider spread, with the AMD Radeon RX 6800 at 0.7% faster and the RTX A5000 at 1.3% faster, suggesting that small GPU differences could shift the combo's rank.

CPU Role

The AMD Ryzen 7 5800XT is an 8-core, 16-thread processor based on the Zen 3 architecture, with a base clock of 3.80 GHz and a boost clock of 4.80 GHz. It features 32 MB of L3 cache and supports DDR4 memory with a dual-channel interface. The CPU's 105 W TDP is modest for its performance class, and its 86th percentile ranking among all CPUs confirms its high-end positioning.

In this game, the CPU's role is most evident at 1080p, where the measured FPS at Low settings reaches 272.1 FPS. This extreme frame rate suggests that the CPU is capable of feeding the GPU far more frames than it can render at lower resolutions. The 8 cores and 16 threads are likely well-utilized by the simulation's logic, which may include physics calculations, component temperature modeling, and system stress test simulations.

The CPU's benchmark scores support its strong performance. The Cinebench R23 multicore score of 23794 and single-core score of 3359 indicate excellent multi-threaded and single-threaded performance. The 3DMark 16-thread score of 7683 and max-thread score of 7680 show consistent scaling across thread counts, which is important for a simulation game that may use multiple threads for different subsystems.

The CPU's nearest rivals in terms of average benchmark score are the AMD Ryzen 7 PRO 5755GE (0.1% faster), AMD Ryzen 7 6800HS (0.3% slower), and AMD Ryzen AI 7 PRO 360 (0.3% faster). These tight margins confirm that the 5800XT is competitively positioned within its performance tier. The 4,150 million transistors on a 74 mm² die at 7 nm process node indicate a dense, efficient design that contributes to its high boost clock of 4.80 GHz.

In the context of this game, the CPU is not the primary bottleneck at any resolution above 1080p. Even at 1080p Ultra, the 128.9 FPS result is likely still CPU-limited, as the GPU has headroom. The transition from Low to Ultra at 1080p costs 143.2 FPS, which is a massive difference, but the CPU maintains high frame rates across all settings. This suggests that the CPU's single-thread performance (Cinebench R23 single-core score of 3359) is sufficient for the game's main thread, while the multi-thread performance handles background simulation tasks.
