Pc Building Simulator

Pc Building Simulator, a simulation title released on 2019-01-28, is benchmarked here with the Intel Core i9-14900K and the AMD Radeon RX 7900 XT. The CPU contributes 24 cores and 32 threads with a 6.00 GHz boost clock, while the GPU brings 20 GB of GDDR6 memory on a 320-bit bus. All FPS figures are measured results from the database, and the combo ranks 307th out of 1769 tested combinations.

Resolution Scaling

At 1080p High, the combo produces 196 FPS; at 1440p High it drops to 126.6 FPS; at 4K High it falls to 65 FPS. The 4K figure is less than half of the 1080p figure, and the 1440p figure sits between the two. This pattern — a steep decline as resolution climbs — indicates that the rendering load scales strongly with pixel count, and the GPU becomes the dominant constraint at higher resolutions.

Looking at Low settings, the scaling is even more pronounced: 397.2 FPS at 1080p, 250 FPS at 1440p, and 130.9 FPS at 4K. The 1080p Low result is the highest measured figure in the entire dataset for this combo, suggesting that at low settings the CPU is capable of feeding the GPU far beyond what the GPU can render at higher resolutions. The gap between Low and Ultra at 1080p is large — 397.2 versus 190.5 — while at 4K the gap narrows to 130.9 versus 62.5. This narrowing indicates that at 4K, the GPU's raw throughput is the limiting factor, whereas at 1080p, the CPU's 24 cores and 32 threads can push frame rates much higher.

The step from 1440p to 4K roughly halves the frame rate at each setting: High falls from 126.6 to 65, Medium from 178 to 94.4, Low from 250 to 130.9, and Ultra from 122 to 62.5. The step from 1080p to 1440p is less severe, with reductions of roughly a third at most settings. This asymmetry is typical of a GPU-bound scenario at 4K, where the RX 7900 XT's 51.48 TFLOPS FP32 throughput and 800.0 GB/s memory bandwidth become the primary determinants of performance. The 4K Low result of 130.9 FPS is more than double the 4K Ultra result of 62.5 FPS, showing that settings have a significant impact even at the highest resolution.

CPU Role

The Intel Core i9-14900K is a 24-core, 32-thread processor with a base clock of 3.20 GHz and a boost clock of 6.00 GHz. Its 36 MB of shared L3 cache and 125 W TDP place it in the top tier of desktop CPUs, and its benchmark percentile of 97 against all CPUs confirms this. In Cinebench R23, the chip scores 49872 multi-core and 7040 single-core; in Geekbench, 20370 multi-core and 3064 single-core. The Passmark multithread score of 58674 and single-thread score of 4697 reinforce the CPU's strength in both heavily threaded and lightly threaded workloads. The CPU supports DDR4 and DDR5 memory on a dual-channel bus, and its PCIe Gen 5 interface with 16 lanes provides ample bandwidth for the GPU.

The nearest rivals in the database are the AMD EPYC 7413 (deltaPct -0.3), the Intel Core i9-14900KF (deltaPct 0.7), the Intel Core Ultra 7 265KF (deltaPct 0.7), and the Intel Core Ultra 7 265K (deltaPct 0.9). The i9-14900K's average benchmark score of 79824 trails the EPYC 7413's 80041 by 0.3 deltaPct and leads the i9-14900KF's 79245 by 0.7 deltaPct. This tight grouping means the CPU is effectively tied with these parts in aggregate performance.

For Pc Building Simulator, the CPU's role is evident in the 1080p Low result of 397.2 FPS — a figure that only a high-core-count, high-boost processor can sustain. The 6.00 GHz boost clock is particularly relevant for a simulation game, where single-threaded logic often drives frame pacing. The CPU's launch MSRP is $589, and its 10 nm process node from Intel, with a die size of 257 mm², underpins its design. At 1440p and 4K, the CPU's influence diminishes as the GPU takes over; the 4K Ultra result of 62.5 FPS is far below the 1080p Low result, indicating that the CPU is not the bottleneck at high resolutions.

How This Combo Ranks

The combination of the Intel Core i9-14900K and the AMD Radeon RX 7900 XT ranks 307th out of 1769 tested combos in Pc Building Simulator. This places it in the upper portion of the field, though not at the very top. The rank reflects the balance between the CPU's 97th-percentile standing and the GPU's 82nd-percentile standing. The CPU is clearly a top-tier part, while the GPU, despite its 20 GB of memory and 800.0 GB/s bandwidth, sits slightly lower in the overall GPU hierarchy.

The GPU's nearest rivals — the NVIDIA GeForce RTX 5080 Mobile (deltaPct 0), the NVIDIA CMP 70HX (deltaPct 0.3), the NVIDIA GeForce MX570 (deltaPct -0.4), and the NVIDIA GeForce RTX 4080 Mobile (deltaPct 0.6) — all have average scores within 0.6 deltaPct of the RX 7900 XT's 38358. This tight grouping means the GPU's performance class is well established, and the combo's rank of 307 is driven more by the CPU's strength than by any GPU outlier behavior.

In the context of 1769 combos, a rank of 307 means the majority of tested systems fall below this pairing. The measured FPS data supports this: even at 4K Ultra, the combo maintains 62.5 FPS, which is a solid result for a simulation title. The rank is a composite measure, and the FPS breakdown shows where this combo excels and where it is merely adequate.

Measured FPS Breakdown

At 1920x1080, the combo delivers 397.2 FPS on Low, 278.4 FPS on Medium, 196 FPS on High, and 190.5 FPS on Ultra. The gap between High and Ultra is small — 196 versus 190.5 — suggesting that Ultra settings add little rendering cost at this resolution. The Low setting, at 397.2 FPS, is the highest measured result in the entire dataset for this combo.

At 2560x1440, the results are 250 FPS on Low, 178 FPS on Medium, 126.6 FPS on High, and 122 FPS on Ultra. The drop from 1080p to 1440p is consistent across settings: Low falls from 397.2 to 250, Medium from 278.4 to 178, High from 196 to 126.6, and Ultra from 190.5 to 122. The 1440p Ultra result of 122 FPS remains well above the 4K Ultra figure of 62.5 FPS, indicating a smooth experience at this resolution. The 1440p Medium result of 178 FPS is nearly double the 4K Medium result of 94.4 FPS, and the 1080p Medium result of 278.4 FPS is substantially higher than the 1440p Medium result.

At 3840x2160, the combo produces 130.9 FPS on Low, 94.4 FPS on Medium, 65 FPS on High, and 62.5 FPS on Ultra. The 4K Ultra result of 62.5 FPS is the lowest in the dataset, but it remains a usable frame rate for a simulation game. The 4K Low result of 130.9 FPS shows that even at 4K, the CPU and GPU together can push frame rates far above the 4K Ultra result when settings are reduced. The progression from Low to Ultra at 4K — 130.9, 94.4, 65, 62.5 — shows a steep drop between Low and Medium, then a more gradual decline to Ultra. The 4K Low result of 130.9 FPS is the highest 4K figure, followed by the 4K Medium result of 94.4 FPS.

GPU Role

The AMD Radeon RX 7900 XT is built on the Navi 31 chip with RDNA 3.0 architecture, featuring 5376 shading units, 336 TMUs, and 192 ROPs. Its base clock is 1387 MHz, its boost clock reaches 2394 MHz, and its game clock is 2025 MHz. The 20 GB of GDDR6 memory on a 320-bit bus delivers 800.0 GB/s of bandwidth, and the card's FP32 throughput is 51.48 TFLOPS. The GPU's benchmark percentile of 82 against all GPUs places it in the upper tier, though below the CPU's 97th percentile. Its launch MSRP is 899 USD. The memory clock is 2500 MHz with 20 Gbps effective data rate, and the pixel rate is 459.6 GPixel/s with a texture rate of 804.4 GTexel/s.

The GPU's nearest rivals in the database are the NVIDIA GeForce RTX 5080 Mobile (deltaPct 0), the NVIDIA CMP 70HX (deltaPct 0.3), the NVIDIA GeForce MX570 (deltaPct -0.4), and the NVIDIA GeForce RTX 4080 Mobile (deltaPct 0.6). All four are within 0.6 deltaPct of the RX 7900 XT's average score of 38358, indicating that the card's performance is tightly clustered with these parts. The 3DMark Steel Nomad DX12 score of 5623 and the Geekbench Vulkan score of 160119 provide additional context for its compute and graphics capabilities. The Passmark G3D score of 29009 and G2D score of 1232 round out the picture.

In Pc Building Simulator, the GPU's role is most visible at 4K. The 4K Ultra result of 62.5 FPS, compared to the 1080p Low result of 397.2 FPS, shows that the GPU is the limiting component at high resolutions. The 20 GB VRAM is more than sufficient for this simulation title, and the 800.0 GB/s bandwidth ensures that texture streaming and memory-bound operations do not become a constraint. The card's 84 RT cores are present, though this game's rendering workload does not appear to stress ray tracing specifically, based on the measured FPS data.

The GPU's 300 W TDP and dual-slot design are consistent with its performance class, and the 2x 8-pin power connectors align with the 700 W suggested PSU. The card's 5 nm process node from TSMC, with 57,700 million transistors on a 529 mm² die, underpins its efficiency. The GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and its bus interface is PCIe 4.0 x16. For this game, the RX 7900 XT delivers strong frame rates at all tested settings, with the 4K Ultra result of 62.5 FPS being the only figure near the lower end of the range.
