Pc Building Simulator

Pc Building Simulator is a simulation title that behaves differently from typical shooters or action games, as the benchmark data for the Intel Core i7-14700K and AMD Radeon RX 7900 XT combination reveals. The measured frame rates across three resolutions and four quality presets indicate a system that is overwhelmingly GPU-bound at higher settings, yet capable of extreme performance when the load is lightened. This analysis walks through the data to determine optimal settings, the role of the GPU, scaling behavior, and the CPU's contribution to the overall experience.

Settings Recommendations

The data shows a clear trade-off between visual fidelity and raw frame rate, with the Ultra preset providing the most demanding workload. At 1920x1080, the Ultra preset yields an average of 186.5 FPS, which is still highly playable but represents a significant drop from the 397 FPS achieved at Low settings. For users prioritizing a smooth experience on high-refresh-rate monitors, the High preset at 1920x1080 offers 199.9 FPS, which is only 6.7% slower than Ultra at that resolution, while likely providing a more stable frame time. At 2560x1440, the High preset delivers 122.5 FPS, which is nearly identical to the Ultra preset's 121.7 FPS, making High the more efficient choice for the same visual quality tier. The Medium preset at 2560x1440, with 174.4 FPS, provides a substantial 42.4% improvement over High, suggesting that Medium is the optimal balance for users with 144Hz QHD panels who want to fully utilize their display's refresh rate. For 4K gaming, the High preset at 65.1 FPS is the only viable option that remains above the 60 FPS threshold; Ultra drops to 60.9 FPS, which is borderline, and Medium at 89.9 FPS is a better target for those who can tolerate slightly lower details. The data indicates that High is the recommended preset for a consistent experience across all resolutions, as it maintains a minimum of 65 FPS at 4K and scales to 199.9 FPS at 1080p. Medium is the alternative for users who want to push higher refresh rates, especially at 1440p, where it achieves 174.4 FPS. Low settings are unnecessary for this hardware, as even Ultra never drops below 60 FPS at any resolution tested.

GPU Role

The AMD Radeon RX 7900 XT is the dominant component in this pairing, and its specifications directly explain the observed frame rates. The GPU features 20 GB of GDDR6 memory on a 320-bit bus, providing a bandwidth of 800.0 GB/s, which is more than sufficient for a simulation game like Pc Building Simulator that does not appear to be memory-capacity constrained at these resolutions. The RDNA 3.0 architecture, built on a 5 nm process with 57,700 million transistors, includes 5376 shading units and 192 ROPs, with a boost clock of 2394 MHz and a game clock of 2025 MHz. These specs translate into a pixel rate of 459.6 GPixel/s and a texture rate of 804.4 GTexel/s, which explains why the GPU can handle the geometry and fill-rate demands of the simulation at 4K Ultra without falling below 60 FPS. The GPU's benchmark scores reinforce this: a Passmark G3D score of 29009 and a 3DMark Steel Nomad DX12 score of 5623 place it in the 82nd percentile of all GPUs, with an average benchmark score of 38358. Its nearest rivals include the NVIDIA GeForce RTX 5080 Mobile (0% delta) and the NVIDIA CMP 70HX (0.3% delta), indicating that this desktop GPU performs on par with high-end mobile parts and specialized mining cards, but its 300 W TDP and dual-slot design are desktop-class. The GPU's role becomes more apparent when examining the FPS drops from Low to Ultra at each resolution: at 1080p, the drop from 397 FPS to 186.5 FPS is a 53% reduction, while at 4K, the drop from 127.6 FPS to 60.9 FPS is a 52% reduction. This consistent proportional drop suggests that the GPU's shading and texture units are the primary bottleneck when settings increase, not the CPU.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals a system that transitions from CPU-bound to GPU-bound depending on the resolution and settings. At Low settings, the 1080p average of 397 FPS drops to 249.2 FPS at 1440p (a 37.2% decrease) and then to 127.6 FPS at 4K (a 67.9% decrease from 1080p). This steep drop at 4K Low indicates that even with minimal graphics load, the GPU is still the limiting factor at that high pixel count. In contrast, at Ultra settings, the 1080p average of 186.5 FPS drops to 121.7 FPS at 1440p (a 34.7% decrease) and then to 60.9 FPS at 4K (a 67.3% decrease from 1080p), showing a similar relative scaling pattern. The data suggests that the CPU, with its 20 cores and 28 threads, can maintain high frame rates at 1080p even on Low settings, as evidenced by the 397 FPS result, but the GPU's pixel throughput becomes the limiting factor as resolution increases. The most telling comparison is between 1080p and 1440p at Medium settings: the drop from 280.9 FPS to 174.4 FPS is a 37.9% reduction, which is nearly identical to the Low setting drop of 37.2%. This consistent scaling across settings indicates that the GPU's fill rate and memory bandwidth are the dominant constraints at 1440p and above. At 4K, the GPU is clearly the bottleneck, as the difference between High (65.1 FPS) and Ultra (60.9 FPS) is only 6.9%, suggesting that the GPU is saturated and additional settings have diminishing returns. The benchmark results indicate that for a 4K experience, users should accept the High preset, while 1080p users can leverage the CPU's strength to achieve frame rates above 280 FPS on Medium.

Measured FPS Breakdown

At 1920x1080, the data shows a wide range of performance across settings. Low settings produce an average of 397 FPS, which is the highest recorded in this test set. Medium settings drop to 280.9 FPS, representing a 29.2% reduction from Low. High settings yield 199.9 FPS, a 28.8% reduction from Medium. Ultra settings produce 186.5 FPS, which is a 6.7% reduction from High. This progression shows diminishing returns as settings increase, with the largest gap between Low and Medium. At 2560x1440, the pattern continues but with lower absolute numbers. Low settings average 249.2 FPS, Medium settings average 174.4 FPS (a 30% reduction from Low), High settings average 122.5 FPS (a 29.8% reduction from Medium), and Ultra settings average 121.7 FPS, which is nearly identical to High. The 1440p Ultra result is only 0.7% lower than High, indicating that the GPU is approaching its limits at this resolution. At 3840x2160, the performance scales down further. Low settings average 127.6 FPS, which is still very playable. Medium settings average 89.9 FPS, a 29.5% reduction from Low. High settings average 65.1 FPS, a 27.6% reduction from Medium. Ultra settings average 60.9 FPS, which is only 6.5% lower than High. The 4K results show that the GPU is the clear bottleneck, as the gap between High and Ultra is small, but the gap between Medium and High is significant. The overall ranking shows this combo at rank 338 out of 1769 combos in the game, placing it in the top 19.1% of tested configurations. The measured data is consistent across all twelve rows, with no anomalies indicating thermal throttling or driver issues.

CPU Role

The Intel Core i7-14700K is a 20-core, 28-thread processor based on the Raptor Lake architecture, with a base clock of 3.40 GHz and a boost clock of 5.60 GHz. Its cache configuration includes 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. In Pc Building Simulator, the CPU's role is most evident at lower resolutions and settings where the GPU is not fully saturated. The 1080p Low result of 397 FPS demonstrates that the CPU can feed the GPU at very high frame rates, which is supported by its strong multi-threaded benchmarks: a Cinebench R23 multi-core score of 44534 and a Passmark multithread score of 52392. The CPU's single-thread performance is also robust, with a Cinebench R23 single-core score of 6287, which is crucial for simulation games that often rely on a single main thread for game logic. The processor's percentile vs all CPUs is 96, placing it in the top 4% of all processors, with an average benchmark score of 70074. Its nearest rivals include the Intel Core i7-14700KF (0% delta) and the AMD Ryzen 9 9950X (-0.5% delta), indicating that the 14700K is competitive with top-tier consumer and even some server parts. However, the data shows that the CPU is not the bottleneck in most scenarios. At 4K Ultra, the FPS drops to 60.9, which is a 67.3% reduction from 1080p Ultra (186.5 FPS), and this reduction is consistent across all settings, confirming that the GPU is the limiting factor at high resolutions. The CPU's 125 W TDP and 10 nm process node allow it to sustain high clock speeds, but in this game, its performance headroom is only fully utilized at 1080p Low and Medium settings. The benchmark results indicate that for users with high-refresh-rate 1080p monitors, the 14700K is sufficient to push the RX 7900 XT to its limits, but at 1440p and above, the GPU's 300 W TDP and compute resources become the primary constraint. The CPU's 33 MB of L3 cache and dual-channel memory support (DDR4 and DDR5) provide adequate bandwidth for the game's data, but the lack of a notable FPS difference between High and Ultra at 1440p (122.5 vs 121.7) suggests that the GPU's shading units are saturated, not the CPU's cores.
