Pc Building Simulator

Pc Building Simulator, a simulation title from 2019, presents an unusual workload where system assembly logic and hardware interaction are rendered in real-time. The combination of an Intel Core i5-13400F and an NVIDIA GeForce RTX 4090 produces a dataset that reveals clear performance hierarchies across resolutions and settings. This analysis examines the measured frames per second (FPS) from the FACT PACK, interpreting the results through the lens of component utilization and in-game ranking.

Resolution Scaling

The measured FPS data shows a predictable decline as resolution increases, but the magnitude of that decline reveals important information about the system's balance. At 1920x1080 with Low settings, the combo achieves 366 FPS. Moving to 2560x1440 at the same Low preset drops the average to 314 FPS, a reduction of 52 FPS or approximately 14.2%. The step to 3840x2160 Low yields 171 FPS, which is a substantial 45.5% drop from the 1440p figure. This pattern indicates that even at Low settings, the transition to 4K resolution begins to place significant demand on the rendering pipeline, though the absolute numbers remain exceptionally high.

For Medium settings, the scaling follows a similar trajectory. The 1080p Medium average is 322 FPS, which falls to 232 FPS at 1440p — a 90 FPS decrease (27.9%). At 4K Medium, the average drops further to 121 FPS, representing a 47.8% reduction from the 1440p result. The minimum FPS figures at Medium settings also scale with resolution: 274 FPS at 1080p, 197 FPS at 1440p, and 103 FPS at 4K. These minimums suggest that frame pacing remains consistent, with no anomalous stutters appearing as resolution increases.

High settings exhibit a similar pattern. At 1080p, the average is 260 FPS. At 1440p, it drops to 164 FPS (a 36.9% decrease), and at 4K, it reaches 86 FPS (a 47.6% decrease from 1440p). Ultra settings show the lowest overall numbers: 247 FPS at 1080p, 156 FPS at 1440p, and 82 FPS at 4K. The Ultra preset at 4K produces the lowest measured average in the entire dataset, which aligns with expectations for a maximum-quality configuration.

The scaling behavior across all settings indicates that the RTX 4090 remains the dominant performance factor at 1080p and 1440p, where the CPU can feed frames quickly enough. However, the sharp drops between 1440p and 4K — particularly at Low settings where the 171 FPS figure is less than half of the 1080p Low result — suggest that pixel throughput becomes the limiting constraint at 4K. The gap between High and Ultra at 4K is small (86 FPS vs 82 FPS, a 4.7% difference), implying that the additional Ultra effects do not scale linearly with the performance cost at that resolution.

How This Combo Ranks

Within the benchmark database, this specific combination of Intel Core i5-13400F and RTX 4090 achieves a combo rank of 146 out of 3,723 tested combinations for Pc Building Simulator. This places the pairing in the top 3.9% of all tested configurations, which is a strong result given the game's simulation nature and the diverse hardware combinations in the database. The rank indicates that this setup outperforms the vast majority of tested systems, though it does not reach the absolute top tier.

The rank can be contextualized by examining the CPU's overall percentile. The i5-13400F sits at the 77th percentile among all CPUs in the benchmark suite, with an average benchmark score of 25,292. Its nearest rivals include the AMD Ryzen 9 6900HS with a score of 25,284 (0% delta), the Intel Core 5 120 with 25,362 (-0.3% delta), the AMD Ryzen 5 5600X3D with 25,365 (-0.3% delta), and the AMD Ryzen 7 6800H with 25,201 (0.4% delta). These near-identical scores suggest that the i5-13400F's compute performance is tightly clustered with several competing processors, meaning the combo rank is likely influenced more by the GPU's capabilities than by CPU superiority.

For the GPU, the RTX 4090 achieves an 88th percentile ranking among all GPUs, with an average benchmark score of 60,347. Its nearest rivals show interesting comparisons: the Intel Arc Pro A60 scores 60,326 (0% delta), the AMD Radeon Pro Vega 48 scores 60,140 (0.3% delta), the AMD Radeon Pro W6600M scores 61,896 (-2.5% delta), and the AMD Radeon PRO V710 scores 58,657 (2.9% delta). The fact that the RTX 4090's benchmark score is nearly matched by these professional and workstation-oriented cards in synthetic tests, yet the combo rank in this game is high, indicates that the game's specific rendering paths favor the GeForce architecture.

The combination of a 77th percentile CPU and an 88th percentile GPU yielding a top-4% combo rank suggests that Pc Building Simulator responds well to the GPU's strengths, and the CPU does not bottleneck the system in a way that drags down the overall ranking. The data indicates that many higher-ranked combos likely feature even stronger CPUs, but the i5-13400F provides sufficient performance to let the RTX 4090 operate near its potential in this title.

GPU Role

The NVIDIA GeForce RTX 4090 is the primary driver of the measured frame rates, and its specifications explain the observed performance. The GPU features 24 GB of GDDR6X memory on a 384-bit bus, providing a bandwidth of 1.01 TB/s. This memory configuration is more than adequate for a simulation game like Pc Building Simulator, which typically does not require massive texture pools. The 24 GB capacity means that even at 4K Ultra settings, VRAM usage would not approach the limit, allowing the GPU to operate without memory-related stutters or texture thrashing.

The GPU's clock speeds are notable: a base clock of 2,235 MHz and a boost clock of 2,520 MHz. These high clocks contribute to the GPU's raw compute throughput, which is measured at 82.58 TFLOPS for FP32 operations. The Ada Lovelace architecture, built on a 5 nm process at TSMC, packs 76,300 million transistors into a 609 mm² die. The GPU also includes 16,384 shading units, 512 texture mapping units, and 176 raster output units, along with 128 ray tracing cores and 512 tensor cores.

In the context of Pc Building Simulator, the RTX 4090's role is to render the game's interface, component models, and simulation environment at high frame rates. The measured data shows that the GPU delivers 366 FPS at 1080p Low, which is far beyond any display's refresh rate capability, indicating that the GPU is not the limiting factor at that resolution and settings combination. However, as resolution increases to 4K, the GPU's pixel fill rate becomes more important. The pixel rate of 443.5 GPixel/s and texture rate of 1,290.2 GTexel/s are sufficient to maintain high frame rates even at 4K, as evidenced by the 171 FPS at 4K Low.

The GPU's benchmark scores provide additional context. Its Passmark G3D score is 38,194, and its 3DMark Steel Nomad DX12 score is 9,223. These synthetic benchmarks align with the real-world performance seen in this game, where the GPU consistently produces high frame rates across all tested configurations. The GPU's percentile rank of 88 among all GPUs confirms that this is a top-tier part, though its nearest rivals in the database are professional cards with similar average scores — a quirk of the benchmark database's scoring methodology rather than an indication of gaming performance equivalence.

Measured FPS Breakdown

The FACT PACK provides 12 measured FPS data points, covering four resolutions and four settings presets. Starting at 1920x1080, the Low preset delivers an average of 366 FPS. The Medium preset averages 322 FPS, with minimum and maximum values of 274 and 370 FPS respectively. High settings produce 260 FPS on average, and Ultra settings yield 247 FPS. The progression from Low to Ultra at 1080p shows a total drop of 119 FPS (from 366 to 247), which represents a 32.5% performance cost for the highest quality preset compared to the lowest.

At 2560x1440, the Low preset averages 314 FPS. Medium settings average 232 FPS, with a minimum of 197 FPS and a maximum of 267 FPS. High settings produce 164 FPS, and Ultra settings yield 156 FPS. The delta between Low and Ultra at this resolution is 158 FPS (from 314 to 156), a 50.3% reduction. The fact that the Low-to-Ultra gap widens from 32.5% at 1080p to 50.3% at 1440p indicates that the higher resolution amplifies the cost of quality settings.

At 3840x2160, the Low preset delivers 171 FPS on average. Medium settings average 121 FPS, with a minimum of 103 and a maximum of 140 FPS. High settings produce 86 FPS, and Ultra settings yield 82 FPS. The Low-to-Ultra difference here is 89 FPS (from 171 to 82), which is a 52.0% reduction. Interestingly, the gap between High and Ultra at 4K is only 4 FPS (86 to 82), suggesting that Ultra settings at this resolution are not substantially more demanding than High — at least in terms of average frame rate.

Comparing across resolutions at the same settings reveals the scaling behavior. For Low settings, 1080p to 1440p shows a 52 FPS drop (366 to 314), and 1440p to 4K shows a 143 FPS drop (314 to 171). For Medium settings, the drops are 90 FPS (322 to 232) and 111 FPS (232 to 121) respectively. For High settings, the drops are 96 FPS (260 to 164) and 78 FPS (164 to 86). For Ultra settings, the drops are 91 FPS (247 to 156) and 74 FPS (156 to 82). The pattern shows that Low and Medium settings experience larger absolute drops when moving from 1440p to 4K, while High and Ultra have smaller absolute drops — likely because they are already closer to the GPU's performance ceiling at lower resolutions.

CPU Role

The Intel Core i5-13400F provides the computational foundation for this combo. This CPU features 10 cores and 16 threads, with a base clock of 2.50 GHz and a boost clock of 4.60 GHz. It is built on Intel's Raptor Lake architecture using a 10 nm process, with a die size of 215 mm². The cache hierarchy includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 20 MB of shared L3 cache. The CPU supports both DDR4 and DDR5 memory in a dual-channel configuration, though the FACT PACK does not specify which was used for testing.

In synthetic benchmarks, the i5-13400F demonstrates strong multi-threaded performance. Its Cinebench R23 multicore score is 22,604, while the single-core score is 3,191. The 3DMark 16-thread score is 7,314, and the max-thread score is 7,307 — nearly identical, suggesting the CPU scales well with additional threads. The Passmark multithread score is 25,032, and the single-thread score is 3,634. These scores indicate that the CPU has ample compute capability for a simulation game, which may involve physics calculations, AI routines, or other background tasks alongside rendering.

The CPU's average benchmark score of 25,292 places it at the 77th percentile among all CPUs. Its nearest rivals show minimal performance deltas: the AMD Ryzen 9 6900HS scores 25,284 (0% delta), the Intel Core 5 120 scores 25,362 (-0.3% delta), the AMD Ryzen 5 5600X3D scores 25,365 (-0.3% delta), and the AMD Ryzen 7 6800H scores 25,201 (0.4% delta). These results suggest that the i5-13400F is competitive with a range of mobile and desktop processors, though none of these rivals are top-tier desktop flagships.

In Pc Building Simulator, the CPU's role appears to be secondary to the GPU, as evidenced by the high frame rates even at 1080p where CPU bottlenecks would typically manifest. The 366 FPS at 1080p Low is above the realm where most CPUs would struggle, indicating that the i5-13400F can keep up with the RTX 4090's frame generation at lower resolutions. The CPU's 10-core configuration with 16 threads provides sufficient parallelism for the game's simulation aspects, though the game's 2019 release date means it likely does not fully utilize all available threads.

The fact that frame rates drop significantly at 4K while remaining high at 1080p confirms that the GPU becomes the limiting factor at higher resolutions, not the CPU. The CPU's boost clock of 4.60 GHz ensures that single-threaded tasks — such as game logic or UI rendering — are handled efficiently. The 20 MB of L3 cache also helps reduce memory latency for frequently accessed data structures in the simulation.

Settings Recommendations

Based on the measured FPS data, the optimal settings preset depends on the target resolution and desired frame rate. At 1920x1080, all settings presets deliver well above 240 FPS, with the lowest being Ultra at 247 FPS. For most users with a 1080p display, Ultra settings provide the best visual quality without sacrificing playability, since even the maximum quality preset maintains a high average frame rate. However, for competitive or high-refresh-rate scenarios, the Medium preset's 322 FPS or Low preset's 366 FPS might be preferable if the display supports refresh rates above 240 Hz.

At 2560x1440, the Medium preset delivers 232 FPS with a minimum of 197 FPS, which is suitable for high-refresh-rate gaming. High settings at 1440p produce 164 FPS, still above the typical 144 Hz refresh rate. Ultra settings at 1440p yield 156 FPS, which is also acceptable for 144 Hz displays. The Low preset's 314 FPS is excessive for most displays and does not offer meaningful benefits over Medium in terms of visual quality. Therefore, for 1440p, Medium or High settings provide the best balance, with High offering superior visuals at a modest performance cost (232 to 164 FPS, a 29.3% reduction).

At 3840x2160, the situation changes. The Low preset averages 171 FPS, Medium averages 121 FPS, High averages 86 FPS, and Ultra averages 82 FPS. For a 60 Hz display, all settings presets exceed the refresh rate, so Ultra settings can be used without issue. For a 120 Hz display, Medium settings are necessary to maintain frame rates above 120 FPS on average (121 FPS). For a 144 Hz display, only Low settings (171 FPS) reliably exceed the refresh rate. The High and Ultra presets at 4K both hover around 82-86 FPS, making them suitable for 60 Hz displays but not for higher refresh rates. Given the minimal difference between High (86 FPS) and Ultra (82 FPS) at 4K, Ultra settings provide marginally better visuals for a negligible frame rate cost.

The overall recommendation is to prioritize resolution over settings for this combo, since the RTX 4090's large performance headroom at lower resolutions allows for maximum quality presets. At 4K, users should choose settings based on their display's refresh rate: Low for 144 Hz, Medium for 120 Hz, and Ultra or High for 60 Hz. At 1440p and 1080p, Ultra settings are recommended for the best visual experience, as the measured frame rates remain high enough for smooth gameplay on virtually any display.
