Pc Building Simulator

The Intel Core i5-13400F paired with the AMD Radeon RX 7900 XT produces a wide, predictable performance envelope in Pc Building Simulator. Measured data show the combination scales from a very capable 366 FPS average at 1080p Low down to 62 FPS at 4K Ultra, meaning each component takes on different roles depending on resolution and preset. The CPU, with a Cinebench R23 multi-core score of 22604 and a single-core score of 3191, is strong enough to keep framerates consistently high at lower resolutions, while the GPU's 800 GB/s memory bandwidth and 51.48 TFLOPS FP32 throughput become the governing factors at 4K. This is a balanced, swift combo for a game that rewards both raw core throughput and pixel throughput, sized well for competitive and simulation play.

Resolution Scaling

The measured FPS values show a steep drop as the internal rendering resolution moves from 1920x1080 to 3840x2160. At 1080p Low, the combo averages 366 FPS; at 1440p Low, it falls to 250 FPS; and at 4K Low it measures 131 FPS. The same pattern holds for every preset: Medium drops from 281 FPS at 1080p to 177 FPS at 1440p and then to 93 FPS at 4K; High goes from 198 to 125 to 65; Ultra from 189 to 119 to 62. The raw decrease from 1080p to 1440p is typically around the same in FPS points, while the larger drop occurs when stepping from 1440p to 4K. For example, at Low the drop from 1080p to 1440p is 127 FPS, but from 1440p to 4K it is 131 FPS. That mild additional fall at 4K points to the increasing pixel-count burden overwhelming even this high-bandwidth GPU. The data shows a scaling pattern that closely matches typical rendering load: at 1080p the CPU is the ceiling, as evidenced by the unusually high low-setting frame rate, while at 1440p and above the RX 7900 XT's pixel-processing power—its 51.48 TFLOPS FP32, 459.6 GPixel/s pixel rate, and 800.0 GB/s memory bandwidth—is what determines the result. For the same preset, the ratio of FPS between resolutions is consistent and not extreme, indicating a smooth, helpfully stable experience without sudden cliffs. The 4K Medium row provides the only incomplete dataset ( min 79, max 105 ), and it confirms that even at 4K the performance is remarkably consistent given the moderate resolution – the min-to-max span is just 27 FPS. All other presets are without min/max, but the averages tell the story of a combo that handles 1080p with room to spare, delivers good performance at 1440p, and only starts to show its limitations at 4K high/ultra settings where the pixel count dominates.

Settings Recommendations

Choosing the optimal preset depends on the target resolution. The data shows that at 1440p, the Ultra preset delivers a smooth 119 FPS again, but High at 125 FPS is almost identical and only 6 FPS faster. At 1080p, even the Ultra preset is a strong 189 FPS, with High at 198 FPS. For a 144Hz monitor at 1440p, High achieves 125 FPS and Ultra reaches 119 - both can hit the refresh rate, but High is a fraction ahead in numeric terms and likely sacrifices none of the visual difference given the similarity. Similarly, at 4K the High preset at 65 FPS is 3 FPS above Ultra’s 62, but the medium step is the real jump: Medium at 93 FPS is 28 FPS above High. Thus, for 4K, Medium is the best balance in the measured rows, providing a far more fluid experience (93 vs 65 FPS) while still lifting the visual detail above Low’s 131 FPS, which is set only for maximum performance and leaves a lot of quality on the table. At 1440p, if one desires high frame rates, the Low preset runs at a massive 160 FPS but at a visual cost; the data suggests Medium at 1440p offers 174 FPS and is the highest preset still exceeding 160. When the goal is the maximum smoothness on a 144Hz screen, Medium at 1440p (177 FPS) or even High (125 FPS) slots well: 1440p suggested to optimize that balance of quality and headroom, the Smart recommendation based on the measured numbers is to pick Medium across all resolutions when seeking a sensible trade‑off: 1080p Medium runs 281, 1440p medium 177, and 4K medium 93 – the latter being the only way to stay above 90 FPS at 4K. Low is never the best choice for sustained play since its framerate excess is beyond even monitors, and Ultra provide diminishing returns at high resolutions while only hurting FPS.

GPU Role

The RX 7900 XT is a pivotal driver in this game, and the measured numbers confirm the GPU is the boundary for high‑resolution settings. Its memory resources are abundant: 20 GB of GDDR6 across a 320‑bit bus yields a bandwidth of 800.0 GB/s, which is more than enough to handle the texture assets of this simulation title. The GPU that has 5376 shading units, 336 TMUs and 192 ROPs, with a base clock of 1387 MHz and a boost of 2394 MHz. Those limits become clear when we process the fact set: at 1440p Medium, the frame rate is 177, and at 4K Medium it falls to 93. The GPU-intensive pixel processing is clearly the limiting factor at 4K—at the Media preset the FPS drops by almost half from 1440p to 2160p, a decrease that aligns with a tre‑to‑quad-pixel increase. In contrast the same resolution step at Low only halved from 250 to 13Ms, which points to the fact that the Low setting reduces overall rendering load so drastically that the GPU is no longer the main bottle‑neck but the CPU's single‑thread performance ( Cinebench R23 single‑core 3191 ) dominates. The GPU draws a TDP of 300 W and requires a 700 W power supply, consistent with its immense compute resources. Across the game, the GPU benchmarks show it sits in percentile 55 among all GPUs in the dataset, with an average benchmark score of 13745. Its nearest rivals in the GPU test are the AMD Radeon 660M (0.5% lower), NVIDIA RTX A2000 Mobile (0.5% lower), and AMD Radeon RX 570X (0.9% lower). That positioning explains why the GPU, while far from the absolute fastest, delivers robust performance in this simulation when combined with a strong CPU, as it is able to sustain high shift rates at loaded resolutions like 4K.

How This Combo Ranks

In the database of tested combinations, the i5‑13400F + RX 7900 XT combination achieves an overall of 699 out of 3723 combos. That means it lands in the upper range of tested pairs, but still below many other combos where both components are higher positioned. The CPU's percentile rank is 77, while the GPU's rank is only 592, a notable asymmetry. The inverse makes clear that the overall standing that is 97 is shaped much more by the strong CPU than by the GPU, which is close to the mid‑range of all GPUs. Compared to CPU nearest rivals, the processor's average benchmark score of 25292 is within 0.3% of the Intel Core 5 120 (score 25362) and the AMD Ryzen 5 5600X3D (score 25365), and exactly matching the AMD Ryzen 9 6900HS at 0.0% difference. That the CPU rivals score similarly low means the combo's rank rests on its unusually fast memory bandwidth and core count, not on a boardry board of brute CPU. For the GPU, the nearest rivals average score (e.g., AMD Radeon 660M at 13812, RTX A2000 13821) are ~0.5% below; the actual difference between 0.87% and 0.0% highlight that the GPU performance is not an outlier, but it is enough to bring the total ranking to the 69 percentile. In the measured game data, this combination matches or exceeds many combinations that rely on faster CPUs but weaker GPUs, because the game is particularly sensitive to strong single‑core performance at low resolutions (Cinebench R23 single a 3191) and to a strong memory bandwidth at high resolutions – both of which this pair provides.

All framerates are measures in average FPS. No min/max values are provided for most preset‑resolution combinations, but the Medium rows carry full min/max spans, showing reliable frame‑time behavior even then. The breakdown confirms that the i5‑13400F + RX 7900 XT handles every category effectively; only the very high 4K settings drag it to below 70 FPS, while anything at 1440p or lower reaches comfortable gaming numbers. The 4K Ultra reading of 62 FPS is the only metric that dips below the usual 60 FPS threshold for fluid gaming, making Ultra at 4K the only significantly challenged scenario. Overall, the dataset strongly suggests a combo that is best tuned for high‑refresh 1440p or high‑detail 4K with a medium preset.
