Pc Building Simulator

Pc Building Simulator is a simulation title where system assembly and component behavior are the core gameplay, and the measured performance of the Intel Core i5-13400F paired with the NVIDIA GeForce RTX 3070 reflects a surprisingly balanced yet resolution-dependent partnership. The data shows a combo that can dominate at 1080p, remains highly capable at 1440p, but begins to show its limits at 4K, where the GPU becomes the primary constraint.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals a classic pattern of GPU-bound behavior at higher resolutions, with CPU headroom becoming apparent only at lower resolutions. At 1080p Low settings, the combo reaches 300.5 FPS, which drops to 188.3 FPS at 1440p Low and then to 98.9 FPS at 4K Low. This represents a 68.1% reduction from 1080p to 4K at Low settings, indicating that the RTX 3070 is the limiting factor even at the lowest graphical presets.

The scaling becomes more pronounced as settings increase. At High settings, the transition from 1080p (151.5 FPS) to 1440p (94.1 FPS) and then to 4K (49.3 FPS) shows a 67.5% total drop. Ultra settings tell a similar story: 143.5 FPS at 1080p, 92.9 FPS at 1440p, and 46.2 FPS at 4K. The gap between 1080p and 1440p at Ultra is 35.3%, while the gap between 1440p and 4K is 50.3%, confirming that the 4K resolution imposes a disproportionately heavy load on the GPU.

Interestingly, the delta between Low and Ultra at each resolution is relatively consistent. At 1080p, Ultra delivers 47.8% of the Low performance; at 1440p, Ultra delivers 49.3% of Low; at 4K, Ultra delivers 46.7% of Low. This consistency suggests that the game's settings scale uniformly across resolutions, with the RTX 3070's 8 GB VRAM and 448.0 GB/s bandwidth providing a stable foundation until 4K, where the pixel count overwhelms the GPU's shader throughput.

The fact that the 1080p Low result (300.5 FPS) is more than double the 4K Ultra result (46.2 FPS) underscores that this game is heavily GPU-limited at high resolutions, with the Core i5-13400F's 10 cores and 16 threads providing ample headroom to avoid CPU bottlenecks even at low settings and high frame rates.

How This Combo Ranks

The combo ranks 818th out of 1769 tested combinations, placing it in the 53.8th percentile of all tested systems. This middle-of-the-pack ranking is noteworthy because the individual components perform well above average in their respective categories: the Core i5-13400F sits in the 82nd percentile among all CPUs, while the RTX 3070 ranks in the 72nd percentile among all GPUs. The combo's overall ranking being lower than either component's individual percentile suggests that the pairing, while effective, does not boost to the top tier of systems tested in this game.

The CPU's nearest rivals provide context for its contribution. The Intel Core i7-13620H scores 25201, a delta of just 0.1% relative to the i5-13400F's average benchmark score of 25236, indicating near-identical CPU performance. The AMD Ryzen 5 5600X3D scores 25365, which is 0.5% higher, and the AMD Ryzen AI 5 PRO 340 scores 25099, 0.5% lower. These margins are negligible, meaning the CPU's performance tier is well established regardless of which rival is considered.

The GPU's nearest rivals show a similar clustering. The AMD Radeon RX 6600 XT scores 27985, a 0.9% delta below the RTX 3070's 28238 average, while the NVIDIA GeForce GTX 980 Ti scores 27956, 1.0% lower. The AMD FirePro S7150 scores 28409, 0.6% higher, and the AMD Radeon R9 M295X scores 28541, 1.1% higher. These small deltas indicate that the RTX 3070 is positioned in a tightly contested performance band, and the combo's rank reflects this competitive but not exceptional standing.

The 818th rank out of 1769 combos means that 951 tested combinations performed better in Pc Building Simulator, likely due to more powerful GPUs or newer architectures. However, the combo's 4K High result of 49.3 FPS and 1440p Ultra result of 92.9 FPS show that it remains viable for high-refresh-rate gaming at mainstream resolutions, even if it does not crack the top half of the database.

GPU Role

The RTX 3070's specifications directly explain its measured performance in this title. The GPU features 8 GB of GDDR6 memory on a 256-bit bus, delivering 448.0 GB/s of bandwidth. The GA104 chip, built on Samsung's 8 nm process, contains 17,400 million transistors across a 392 mm² die. With 5888 shading units, 184 texture mapping units, and 96 raster operation units, the GPU offers substantial compute resources, including 46 ray tracing cores and 184 tensor cores.

Clock speeds are a critical factor: the base clock of 1500 MHz boosts to 1725 MHz, and memory runs at 1750 MHz (14 Gbps effective). These clocks, combined with the 256-bit memory bus, allow the card to reach 20.31 TFLOPS of FP32 performance. The pixel rate of 165.6 GPixel/s and texture rate of 317.4 GTexel/s provide the raw throughput needed for the simulation's rendering workload. The GPU's TDP is 220 W, with a suggested PSU of 550 W, and it connects via PCIe 4.0 x16.

In Pc Building Simulator, the GPU's role is evident from the measured FPS. At 1080p Low, the card produces 300.5 FPS, which drops to 213.6 FPS at Medium, 151.5 FPS at High, and 143.5 FPS at Ultra. The relatively small gap between High (151.5) and Ultra (143.5) at 1080p suggests that the highest settings introduce diminishing returns, likely due to the game's simulation-focused rendering rather than pure pixel pushing. At 4K, the Ultra preset yields 46.2 FPS, which is below the 60 FPS threshold, indicating that the 8 GB VRAM and 448.0 GB/s bandwidth are insufficient for smooth 4K gaming on this title.

The GPU's benchmark scores corroborate its mid-range positioning: a 3DMark Steel Nomad DX12 score of 3162, Geekbench OpenCL of 123479, and Vulkan of 120664. The Passmark G3D score of 22214 and GPU Compute score of 11195 place it in a solid but not elite tier. The percentileVsAllGpus of 72 confirms that it outperforms roughly three-quarters of all GPUs in the database, yet the 4K results show that it cannot fully saturate a 4K display in this game.

Measured FPS Breakdown

At 1080p, the combo delivers exceptional performance across all settings. Low settings produce 300.5 FPS, Medium yields 213.6 FPS, High achieves 151.5 FPS, and Ultra bottoms out at 143.5 FPS. These numbers indicate that the RTX 3070 has ample headroom for competitive or high-refresh-rate gaming at this resolution, with even the Ultra preset maintaining frame rates well above 144 Hz.

Moving to 1440p, performance remains strong but drops as expected. Low settings deliver 188.3 FPS, Medium produces 134.1 FPS, High reaches 94.1 FPS, and Ultra settles at 92.9 FPS. The drop from High to Ultra is minimal (1.2 FPS), suggesting that the Ultra preset at this resolution is not significantly more demanding than High, possibly due to the game's asset streaming behavior. The 1440p results show that the combo can drive high-refresh-rate monitors at Medium settings (134.1 FPS) and remains playable at Ultra (92.9 FPS).

At 4K, the GPU's limitations become apparent. Low settings produce 98.9 FPS, which is still smooth, but Medium drops to 68.8 FPS, High to 49.3 FPS, and Ultra to 46.2 FPS. The gap between High (49.3) and Ultra (46.2) is just 3.1 FPS, indicating that the Ultra preset offers negligible visual improvement at a modest performance cost. The 4K results show that the combo is only suitable for 4K gaming at Low or Medium settings, with High and Ultra falling below the 60 FPS target.

The scaling across settings is consistent: at every resolution, Low to Medium yields a significant gain, while High to Ultra shows diminishing returns. For instance, at 1080p, Low to Medium is a 28.9% drop, Medium to High is a 29.1% drop, and High to Ultra is just a 5.3% drop. This pattern repeats at 1440p (28.8%, 29.8%, 1.3%) and 4K (30.4%, 28.3%, 6.3%), confirming that the Ultra preset in Pc Building Simulator is not particularly demanding relative to High.

Settings Recommendations

For 1080p gaming, the Ultra preset at 143.5 FPS is the obvious choice, as it provides maximum visual fidelity while still maintaining frame rates that exceed most high-refresh-rate displays. There is no reason to sacrifice quality at this resolution, given the 143.5 FPS result is only 8 FPS lower than High. For users with 240 Hz monitors, the Medium preset at 213.6 FPS offers a better balance of visual quality and frame rate, though Low at 300.5 FPS is available for esports-style play.

At 1440p, the High preset at 94.1 FPS is the recommended starting point, as it delivers smooth gameplay on standard 60 Hz and 144 Hz monitors. The Ultra preset at 92.9 FPS is nearly identical in performance and can be selected if the user prioritizes visual fidelity, as the 1.2 FPS difference is imperceptible. For users with 144 Hz displays, the Medium preset at 134.1 FPS is the best choice, providing a 42.6% improvement over High while still looking good.

At 4K, the situation is more constrained. The Low preset at 98.9 FPS is the only option that comfortably exceeds 60 FPS, making it the recommended preset for 4K gaming. Medium at 68.8 FPS is playable and offers better visuals, but it requires a tolerance for frame rates below 70 FPS. High at 49.3 FPS and Ultra at 46.2 FPS are not recommended for 4K, as they fall below the 60 FPS threshold and would result in a suboptimal experience. Given that the gap between High and Ultra is only 3.1 FPS, users who insist on 4K should either accept Medium or reduce the resolution to 1440p for higher settings.

The data indicates that this combo is best suited for 1080p and 1440p gaming, where it can take full advantage of high refresh rates. For 4K, the RTX 3070's 8 GB VRAM and 448.0 GB/s bandwidth are insufficient for High or Ultra presets, making Low the only truly smooth option. The Core i5-13400F's CPU performance, as evidenced by its 82nd percentile ranking and 21279 Cinebench R23 multicore score, ensures that the CPU will never bottleneck the GPU in this simulation, allowing the GPU to be the sole determinant of frame rates.
