Resolution Scaling

The measured frames per second across the three tested resolutions reveal a clear pattern of GPU-bound scaling, but with an interesting twist at the higher settings. At 1080p with Low settings, the combination of the AMD Ryzen 9 7900X and NVIDIA GeForce RTX 5080 produces 424.5 FPS. Moving to 1440p at the same setting drops performance to 312.9 FPS, a reduction of roughly 26%. The jump to 4K Low brings the average down to 164.7 FPS, which represents a 47% drop from the 1440p figure.

This scaling curve suggests that the RTX 5080 is the primary limiting component even at lower settings, as the frame rates scale almost inversely with pixel count. The 1080p to 4K transition at Low settings shows a 61% total reduction in frame rate. However, the data becomes more telling when examining the High and Ultra presets. At High settings, the 1080p score of 247.9 FPS drops to 154.9 FPS at 1440p—a 37.5% decrease—and then to 80.7 FPS at 4K, another 48% reduction. The Ultra preset follows a similar trajectory: 236.1 FPS at 1080p, 147.5 FPS at 1440p, and 77.4 FPS at 4K.

The consistency of these percentage drops across presets indicates that the rendering pipeline is uniformly taxing the GPU. There is no evidence of a CPU bottleneck appearing at lower resolutions, which would typically manifest as a plateau in frame rates. Instead, the data shows that the Ryzen 9 7900X with its 12 cores and 24 threads is feeding the RTX 5080 adequately at every resolution. The 4K Ultra result of 77.4 FPS is remarkably close to the 4K High result of 80.7 FPS, suggesting that the additional workload from Ultra settings is minimal at this resolution, likely due to the game's simulation nature rather than heavy graphical effects.

Settings Recommendations

The measured rows provide a clear hierarchy of performance for different quality presets. At 4K, the jump from Low to Medium costs 49.2 FPS (from 164.7 to 115.5), while moving from Medium to High costs another 34.8 FPS (to 80.7). The Ultra preset at 4K delivers 77.4 FPS, only 3.3 FPS less than High. This tight grouping at the top end suggests that High and Ultra are nearly equivalent in performance cost at 4K, making High the more sensible choice for most users seeking a balance between visual fidelity and smoothness.

At 1440p, the data shows a wider spread. Low delivers 312.9 FPS, Medium drops to 224.5 FPS, High hits 154.9 FPS, and Ultra manages 147.5 FPS. The difference between High and Ultra here is only 7.4 FPS, which is negligible in practical terms. Given that the 4K Ultra score of 77.4 FPS remains above the 60 FPS threshold for smooth gameplay, the data suggests that High settings at 4K provide the best overall experience, as it offers a meaningful improvement over Medium (80.7 vs 115.5 FPS) without the diminishing returns seen when pushing to Ultra.

For 1080p users, the story is different. The Low preset achieves 424.5 FPS, Medium reaches 352.2 FPS, High delivers 247.9 FPS, and Ultra produces 236.1 FPS. The gap between High and Ultra is again small (11.8 FPS), but all presets are well above any reasonable refresh rate target. The data implies that at 1080p, even Ultra settings leave substantial headroom, making the choice of preset more about visual preference than performance necessity.

How This Combo Ranks

The AMD Ryzen 9 7900X paired with the NVIDIA GeForce RTX 5080 achieves rank 50 out of 1769 tested combinations in Pc Building Simulator. This places the combo in the top 2.8% of all configurations tested for this game. The high ranking is consistent with the measured frame rates, which show the system capable of exceeding 400 FPS at 1080p Low and maintaining over 75 FPS at 4K Ultra.

The CPU's percentile ranking of 93 against all CPUs indicates that the Ryzen 9 7900X is in the top 7% of processors, while the GPU's percentile of 89 places it in the top 11% of graphics cards. The combination of two high-percentile components yields a system that ranks exceptionally well in this simulation game. The data suggests that this pairing is particularly well-suited for Pc Building Simulator, where the CPU's 12 cores and 24 threads may contribute to the simulation aspects, while the GPU handles the visual rendering efficiently.

The rank of 50 out of 1769 also implies that there are 49 other combinations that perform better, likely featuring even higher-end GPUs or CPUs. However, the measured performance at 4K Ultra of 77.4 FPS demonstrates that this combo is more than capable of delivering a smooth experience at the highest settings and resolution tested.

GPU Role

The NVIDIA GeForce RTX 5080 brings substantial memory resources to this game, with 16 GB of GDDR7 memory on a 256-bit bus delivering 960.0 GB/s of bandwidth. The GPU's base clock of 2295 MHz and boost clock of 2617 MHz provide the computational throughput needed for the high frame rates observed in the measured data. The 10752 shading units and 112 ROPs contribute to the pixel throughput of 293.1 GPixel/s, which helps explain the performance at 4K resolutions.

The GPU's FP32 performance of 56.28 TFLOPS is a strong indicator of its raw compute capability, and the data reflects this in the 4K Low result of 164.7 FPS. The 84 RT cores and 336 tensor cores may not be heavily utilized in a simulation game like Pc Building Simulator, but their presence ensures compatibility with any DirectX 12 Ultimate features. The GPU's percentile ranking of 89 against all GPUs places it in the top 11%, and its nearest rivals show a narrow performance delta: the Intel Arc A570M is 1.6% behind, while the Intel Arc Pro A60 is 1.9% ahead.

The 360 W TDP and suggested 750 W PSU indicate that this GPU requires substantial power delivery, but the measured frame rates justify the power envelope. The memory clock of 1875 MHz with 30 Gbps effective speed provides the bandwidth necessary to feed the GPU's processing units at 4K Ultra settings, where the measured 77.4 FPS demonstrates no memory bottleneck.

Measured FPS Breakdown

At 1920x1080, the data shows the full range of settings performance. Low settings produce 424.5 FPS, Medium drops to 352.2 FPS, High delivers 247.9 FPS, and Ultra achieves 236.1 FPS. The progression from Low to Ultra represents a 44.4% reduction in frame rate, indicating that the graphical settings have a significant impact at this resolution.

Moving to 2560x1440, the measured scores are 312.9 FPS at Low, 224.5 FPS at Medium, 154.9 FPS at High, and 147.5 FPS at Ultra. The reduction from Low to Ultra here is 52.9%, showing that the higher resolution amplifies the cost of increased settings. The gap between High and Ultra remains tight at 7.4 FPS, suggesting that Ultra settings add little visual benefit relative to High at 1440p.

At 3840x2160, the measurements show 164.7 FPS at Low, 115.5 FPS at Medium, 80.7 FPS at High, and 77.4 FPS at Ultra. The Low to Ultra reduction is 53.0%, consistent with the 1440p pattern. The 4K High and Ultra scores are separated by only 3.3 FPS, making High the more efficient choice at this resolution. The overall trend across all resolutions shows that the RTX 5080 handles the transition from 1080p to 4K with predictable scaling, and the Ryzen 9 7900X keeps pace without becoming a limiting factor.

CPU Role

The AMD Ryzen 9 7900X, with its 12 cores and 24 threads, provides substantial multi-threaded processing capability that benefits simulation games. The base clock of 4.70 GHz and boost clock of 5.60 GHz ensure strong single-thread performance, which is reflected in the 3dmark single-thread score of 1093 and the Cinebench R23 single-core score of 6168. The CPU's 64 MB of shared L3 cache and 1 MB L2 per core provide ample cache for the game's simulation logic.

The CPU's 93rd percentile ranking against all CPUs indicates that it outperforms 93% of tested processors. In Cinebench R23 multicore, the 43695 score demonstrates the CPU's ability to handle heavily threaded workloads, which is relevant for a game that simulates PC building and operation. The Passmark multithread score of 51406 and the average benchmark score of 50556 further confirm the CPU's strong overall performance.

The nearest rivals show that the Ryzen 9 7900X is closely matched with the Intel Core Ultra 5 235, which is 0.1% behind in average score, while the AMD Ryzen 9 5900XT is 0.4% behind. This tight grouping suggests that the CPU's performance is well-established in its class. The measured FPS data shows no signs of CPU bottlenecking, as even at 1080p Low with 424.5 FPS, the system continues to scale with GPU settings, indicating that the 12 cores and 24 threads provide sufficient processing power to feed the RTX 5080 at all tested resolutions and settings.
