Pc Building Simulator

The Intel Core i5-13400F paired with the AMD Radeon RX 6650 XT delivers a highly playable experience in Pc Building Simulator, but the data reveals a system that transitions from being CPU-bound at lower resolutions to firmly GPU-limited at 4K. The measured frames per second across the three resolutions and four quality presets paint a clear picture of where the bottleneck shifts, and the benchmark results indicate that this combination is a capable, if not spectacular, performer in this specific simulation title.

Resolution Scaling

The FPS drop from 1080p to 4K is dramatic and tells a story of increasing GPU pressure. At Low settings, the system produces 235.8 FPS at 1920x1080, which falls to 146.2 FPS at 2560x1440 — a 38% reduction — and then plummets to 79.1 FPS at 3840x2160, a further 46% reduction from 1440p. This steep decline suggests that at 1080p, the CPU is doing the heavy lifting, and the GPU is far from saturated. The gap between 1080p and 1440p at Low settings is 89.6 FPS, while the gap between 1440p and 4K is 67.1 FPS, showing that the scaling is somewhat non-linear but consistently steep.

At High settings, the pattern is similar but with a lower ceiling. The system hits 119.2 FPS at 1080p, drops to 74.4 FPS at 1440p, and then falls to 39.4 FPS at 4K. The percentage drop from 1080p to 4K is about 67%, which is almost identical to the 66% drop seen at Low settings. This consistency indicates that the GPU is the limiting factor at 4K regardless of the preset, as the relative cost of rendering each pixel increases uniformly. The Ultra preset mirrors High almost exactly, with 110.1 FPS at 1080p, 70.8 FPS at 1440p, and 39.4 FPS at 4K, reinforcing that Ultra and High are nearly identical in cost for this title.

What’s curious is the behavior at Medium settings. The system produces 165.7 FPS at 1080p, 102.8 FPS at 1440p, and 54.8 FPS at 4K. The 1080p-to-1440p drop is 62.9 FPS, but the 1440p-to-4K drop is 48 FPS, which is a smaller absolute decline than at Low settings. This suggests that at Medium, the balance between CPU and GPU load shifts slightly, but the overall trend remains: the component limiting performance is the graphics card once you approach 4K. The data implies that for a smooth 60 FPS experience at 4K, the RX 6650 XT is simply out of its depth, as even Low settings only manage 79.1 FPS, leaving little headroom.

GPU Role

The AMD Radeon RX 6650 XT is built on the RDNA 2.0 architecture with a Navi 23 chip, featuring 8 GB of GDDR6 memory on a 128-bit bus. That memory configuration provides a bandwidth of 280.3 GB/s, which is a solid figure for a card in this class but proves insufficient for heavy 4K workloads. The benchmark results show that the GPU’s average benchmark score of 29024 places it in the 72nd percentile of all GPUs, and its nearest rivals include the AMD Radeon RX 6800M with a deltaPct of 0 and the AMD Radeon RX 470 with a deltaPct of 0.1. This means the RX 6650 XT is essentially tied with those cards in synthetic tests, yet its real-world performance in Pc Building Simulator shows clear limitations at higher resolutions.

The clock speeds are notable: the base clock is 2055 MHz, the game clock is 2410 MHz, and the boost clock reaches 2635 MHz. These are high frequencies for a mid-range card, and they help explain why the card performs admirably at 1080p, where the 8 GB VRAM is less likely to be a constraint. However, the 128-bit memory bus becomes a bottleneck at 4K, as the pixel fill rate of 168.6 GPixel/s and texture rate of 337.3 GTexel/s are simply not enough to maintain high frame rates. The FP32 performance of 10.79 TFLOPS is respectable, but the data shows that this compute power is not fully utilized in a simulation game that likely relies more on draw calls and memory bandwidth than raw shader throughput.

The GPU’s end-of-life production status and its predecessor/successor designations (Navi to Navi III) suggest it is a transitional product. In this game, the 4K results — with High and Ultra both capping at 39.4 FPS — indicate that the card hits a hard wall around that resolution, regardless of how much you lower the settings. The fact that Low settings at 4K only achieve 79.1 FPS, which is barely above the 60 FPS threshold, underscores that the GPU is the dominant factor in 4K performance.

Settings Recommendations

For a balanced experience, the benchmark results point toward Medium settings as the sweet spot for most users. At 1920x1080, Medium delivers 165.7 FPS, which is more than enough for any display, and it offers a significant improvement over Low’s 235.8 FPS without the visual penalty of the lowest preset. At 2560x1440, Medium produces 102.8 FPS, which is comfortably above the 60 FPS target and only 43.4 FPS lower than Low. The jump from Medium to High at 1440p is a drop of 28.4 FPS, which is a noticeable sacrifice for potentially marginal visual gains in a simulation title where the camera often remains static.

At 4K, the recommendation changes entirely. No preset achieves a consistent 60 FPS, with High and Ultra both stuck at 39.4 FPS and Medium at 54.8 FPS. Low is the only option that breaks 60 FPS, hitting 79.1 FPS, but that comes with the lowest visual quality. For users with a 4K display, the data suggests that this combo is not ideal, and you would need to accept either Low settings or a lower resolution. If you prioritize smoothness over fidelity, Low at 4K is the playable choice; if you prefer visual quality, you should drop to 1440p and use High or Ultra, which provide 74.4 FPS and 70.8 FPS respectively.

The Ultra preset offers almost no benefit over High in this game, with a difference of only 0.1 FPS at 4K (39.4 vs 39.4) and 3.6 FPS at 1080p (110.1 vs 119.2). This indicates that the Ultra settings are likely adding effects that the RX 6650 XT cannot render efficiently, making High the more practical choice for those seeking the best visual-to-performance ratio.

FAQ

*Q: Can this combo run Pc Building Simulator at 60 FPS on a 4K monitor?*

A: Only at Low settings, where it achieves 79.1 FPS. At Medium, it drops to 54.8 FPS, and at High or Ultra, it falls to 39.4 FPS, so a stable 60 FPS is not achievable at higher presets.

Q: What is the best resolution for this system to maintain a high frame rate?

A: At 1920x1080, all settings exceed 110 FPS, with Low reaching 235.8 FPS. At 2560x1440, Medium and above stay above 70 FPS, making 1440p a viable option for high refresh rates.

Q: How does the RX 6650 XT compare to its nearest rivals in this game?

A: The GPU’s average benchmark score is 29024, with a deltaPct of 0 against the AMD Radeon RX 6800M and 0.1 against the AMD Radeon RX 470, indicating near-identical synthetic performance, but real-world results vary by game.

Q: Is the CPU or GPU more important for this game’s performance at 1080p?

A: At 1080p, the high FPS figures (235.8 at Low, 165.7 at Medium) suggest the CPU is not the limiting factor, as the GPU has headroom to spare. The bottleneck emerges at 4K, where the GPU becomes the clear constraint.

Q: Does the Ultra preset provide a better experience than High?

A: No, the measured FPS shows Ultra is nearly identical to High, with a difference of only 3.6 FPS at 1080p and 0.1 FPS at 4K. High is effectively the same performance with less visual overhead.

Q: What does the frame rate drop from 1080p to 4K indicate about the system?

A: The average FPS drops by roughly two-thirds from 1080p to 4K across all settings, confirming that the RX 6650 XT’s 8 GB VRAM and 128-bit memory bus are the primary limitations at higher resolutions.

How This Combo Ranks

The Intel Core i5-13400F and AMD Radeon RX 6650 XT combination ranks 1120 out of 1769 tested combos in Pc Building Simulator, placing it in the lower-middle tier of the benchmark database. This ranking is somewhat surprising given the individual component scores — the CPU sits in the 82nd percentile of all CPUs, and the GPU is in the 72nd percentile — but it suggests that the pairing does not synergize perfectly for this specific title. The combo’s rank implies that many other combinations, likely with higher-end GPUs, achieve better results in this simulation game, which may be more sensitive to GPU memory bandwidth than raw compute power.

The CPU’s nearest rivals include the Intel Core i7-13620H with a deltaPct of 0.1, meaning the i5-13400F is essentially tied with that mobile chip, and the AMD Ryzen 5 5600X3D, which is 0.5% slower in average score. This indicates that the processor is not a weak link in the system. Similarly, the GPU’s nearest rivals are within 0.6% of its score, so the graphics card is also competitively positioned. The low combo rank, therefore, is not due to any single component being subpar, but rather the combination failing to excel in this game’s specific workload, which may favor different hardware characteristics.

CPU Role

The Intel Core i5-13400F is a 10-core, 16-thread processor based on the Raptor Lake architecture, with a base clock of 2.50 GHz and a boost clock of 4.60 GHz. Its 20 MB of shared L3 cache and dual-channel memory support for DDR4 and DDR5 provide a solid foundation for gaming. In synthetic benchmarks, the CPU achieves a Cinebench R23 multicore score of 21279 and a single-core score of 3004, placing it in the 82nd percentile of all CPUs. These scores indicate strong multi-threaded performance, which is relevant for simulation games that may use multiple threads for physics or AI calculations.

However, in Pc Building Simulator, the CPU’s role appears secondary to the GPU. At 1080p Low, the system produces 235.8 FPS, which is far above typical display refresh rates, suggesting the CPU is not a bottleneck at that resolution. The single-thread performance, measured at 960 in 3DMark single-thread and 3634 in PassMark single-thread, is more than adequate for this game’s logic. The data shows that as resolution increases, the FPS drops proportionally, indicating that the GPU takes over as the limiting factor, and the CPU’s high core count and clock speeds do not compensate for the GPU’s memory limitations. The CPU’s nearest rival, the Intel Core i7-13620H, is within 0.1% in average score, confirming that the i5-13400F is not holding back the system in any meaningful way.

Measured FPS Breakdown

At 1920x1080, the system delivers its best performance. Low settings produce 235.8 FPS, Medium 165.7 FPS, High 119.2 FPS, and Ultra 110.1 FPS. The gap between Medium and High is 46.5 FPS, which is substantial, while the gap between High and Ultra is only 9.1 FPS. This suggests that High is the most efficient preset at 1080p, offering a significant quality boost over Medium with a relatively small FPS cost.

At 2560x1440, the numbers drop but remain playable. Low reaches 146.2 FPS, Medium 102.8 FPS, High 74.4 FPS, and Ultra 70.8 FPS. The difference between Medium and High is 28.4 FPS, and the difference between High and Ultra narrows to just 3.6 FPS. For a 1440p monitor, Medium is the clear choice for high refresh rates, while High still provides over 70 FPS for standard 60 Hz displays.

At 3840x2160, the system struggles. Low manages 79.1 FPS, Medium 54.8 FPS, and both High and Ultra are locked at 39.4 FPS. The drop from 1440p to 4K at Low is 67.1 FPS, while at High it is 35 FPS. The fact that High and Ultra produce identical results at 4K indicates that the GPU has hit a hard limit, likely due to VRAM capacity or memory bandwidth. The data suggests that 4K is not a viable resolution for this combo unless you are willing to use Low settings and accept the visual trade-offs.
