Pc Building Simulator

Pc Building Simulator is a simulation title that tasks the system with managing menus, 3D part models, and benchmark overlays rather than the relentless physics and particle workloads of a shooter. The measured FPS data for the AMD Ryzen 9 5900X with the NVIDIA GeForce RTX 4070 shows a configuration that is decisively GPU-limited at higher resolutions, yet reveals strong CPU headroom at 1080p. The combination ranks 921st out of 3723 tested combos, placing it in the top quartile of all systems tested for this specific game.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent, indicating that the rendering load scales predictably with pixel count. At High settings, the average frame rate falls from 184 FPS at 1920x1080 to 116 FPS at 2560x1440, a reduction of 68 FPS. Moving from 1440p to 3840x2160 brings the average down to 61 FPS, another 55 FPS drop. This trajectory shows that the RTX 4070 is the primary performance limiter once the resolution climbs past 1080p.

At Low settings, the scaling pattern is even more pronounced. The system produces 349 FPS at 1080p, which drops to 232 FPS at 1440p and then to 121 FPS at 4K. The delta between 1080p and 4K at Low settings is 228 FPS, suggesting that the GPU is being saturated by the sheer pixel throughput at 4K, regardless of the reduced graphical complexity.

The Medium settings row provides the only complete min/max data across all resolutions. At 4K Medium, the average is 86 FPS with a minimum of 73 and maximum of 99. At 1440p Medium, the average jumps to 164 FPS with a range of 140 to 189. At 1080p Medium, the average reaches 260 FPS with a spread from 221 to 299. The widening gap between minimum and maximum FPS at lower resolutions (26 FPS at 4K, 49 FPS at 1440p, 78 FPS at 1080p) indicates that while the GPU handles the baseline load, other system components introduce more variance when the frame rate ceiling is higher.

The data suggests that at 1080p, the RTX 4070 is not the bottleneck. The jump from 184 FPS at High to 349 FPS at Low (a 165 FPS difference) shows that the GPU has headroom to spare when settings are reduced. The limiting component at 1080p is likely the CPU or the game's engine logic, given that the Ryzen 9 5900X has 12 cores and 24 threads. At 4K, however, the GPU is clearly the limiting factor, as the difference between Low and High settings is only 60 FPS (121 vs 61), a much smaller gap that reflects the GPU's raw pixel pushing limits.

GPU Role

The NVIDIA GeForce RTX 4070 is built on the Ada Lovelace architecture with a 5 nm process node. It carries 12 GB of GDDR6X memory on a 192-bit bus, providing 504.2 GB/s of memory bandwidth. The GPU operates with a base clock of 1920 MHz and a boost clock of 2475 MHz, with memory clocked at 1313 MHz (21 Gbps effective). These specifications are directly relevant to the measured FPS data, particularly at higher resolutions where memory bandwidth becomes critical.

Looking at the 4K results, the RTX 4070 manages 61 FPS at High settings and 58 FPS at Ultra. The narrow 3 FPS gap between High and Ultra suggests that the GPU is nearing its memory or compute ceiling, as additional graphical features at Ultra do not degrade performance proportionally. The 12 GB VRAM buffer is sufficient for this title at 4K, as there is no evidence of memory-related stutters in the min FPS data (73 FPS at 4K Medium is the only reported minimum, and it is relatively stable).

The GPU's nearest rivals in the benchmark database include the NVIDIA Tesla P4 (0.1% higher average score), AMD Radeon RX Vega 56 (0.4% higher), NVIDIA GeForce RTX 4080 Mobile (1.3% lower), and AMD Radeon PRO W6400 (1.3% higher). These comparisons are based on the aggregate benchmark score of 37648, which places the RTX 4070 in the 81st percentile of all GPUs. In this game specifically, the RTX 4070's 29.15 TFLOPS of FP32 compute and 455.4 GTexel/s texture rate appear sufficient for smooth 1440p gameplay, as evidenced by the 110 FPS average at Ultra settings.

The 200 W TDP and PCIe 4.0 x16 interface are standard for this class of GPU. The data shows that the RTX 4070's performance scales well with resolution until 4K, where it delivers playable but not excessive frame rates. The 3840x2160 Ultra result of 58 FPS is just below the 60 FPS threshold, indicating that users seeking a locked 60 FPS at 4K would need to dial back to High settings or rely on the 86 FPS Medium preset.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest performance. Low settings produce an average of 349 FPS, followed by Medium at 260 FPS (min 221, max 299), High at 184 FPS, and Ultra at 175 FPS. The difference between High and Ultra is only 9 FPS, suggesting that the Ultra preset adds features that have minimal impact on this resolution's GPU load. The 1080p results are uniformly above 170 FPS, indicating this combo is well-suited for high-refresh-rate monitors at this resolution.

Moving to 2560x1440, the averages drop but remain strong. Low settings yield 232 FPS, Medium produces 164 FPS (min 140, max 189), High achieves 116 FPS, and Ultra delivers 110 FPS. The gap between High and Ultra narrows to 6 FPS at 1440p, similar to the 1080p pattern. The minimum FPS at Medium (140) still exceeds 60 FPS by a wide margin, so there is no risk of stuttering during typical gameplay.

At 3840x2160, performance becomes more modest. Low settings average 121 FPS, Medium averages 86 FPS (min 73, max 99), High averages 61 FPS, and Ultra averages 58 FPS. The 4K results show a clear step-down: users must choose between 121 FPS at Low or 61 FPS at High, with Ultra falling just short of 60 FPS. The min FPS at 4K Medium (73) is still well above the playability threshold, but the overall frame rates indicate that 4K requires compromises.

The data across all resolutions shows a consistent pattern: Medium settings offer the best balance of visual quality and performance, with the only complete min/max data available. At 1080p Medium, the system averages 260 FPS with a maximum of 299, which is close to the 349 FPS ceiling of Low settings. At 1440p Medium, the 164 FPS average is 48 FPS higher than High settings, and at 4K Medium, the 86 FPS average is 25 FPS higher than High.

Settings Recommendations

Based on the measured rows, the Medium preset provides the most compelling experience across all three resolutions. The data shows that Medium settings maintain at least 86 FPS at 4K, which is above the standard 60 FPS threshold, while delivering 164 FPS at 1440p and 260 FPS at 1080p. The min FPS values at Medium (73 at 4K, 140 at 1440p, 221 at 1080p) confirm that this preset avoids severe frame drops.

For users with a 1080p display, the High preset at 184 FPS is the recommended choice, as it offers a substantial visual upgrade over Medium (260 FPS) while still exceeding the refresh rate of most 144 Hz monitors. The Ultra preset at 175 FPS is only 9 FPS slower than High, so it is also viable if the user wants maximum visual fidelity without significant performance loss.

At 1440p, the High preset at 116 FPS is ideal for 120 Hz monitors, while Medium at 164 FPS suits 165 Hz displays. The Ultra preset at 110 FPS is only 6 FPS behind High, so the choice between these two depends on whether the user prefers extra graphical effects or a slightly higher frame rate. Low settings at 232 FPS are unnecessary at this resolution unless the user has a 240 Hz monitor.

For 4K, the Medium preset at 86 FPS is the clear winner, providing a comfortable margin above 60 FPS. The High preset at 61 FPS is acceptable for users who prioritize visuals over frame rate, but it leaves little headroom for demanding scenes. The Ultra preset at 58 FPS is borderline, as it dips below the 60 FPS threshold. The Low preset at 121 FPS is overkill for 60 Hz displays and sacrifices too much visual quality.

CPU Role

The AMD Ryzen 9 5900X is a 12-core, 24-thread processor based on the Zen 3 architecture (Vermeer). It has a base clock of 3.70 GHz and a boost clock of 4.80 GHz, with 64 MB of L3 cache. The CPU's aggregate benchmark score is 41376, placing it in the 87th percentile of all CPUs. Its nearest rivals include the Intel Core Ultra 7 366H (0.3% higher), Intel Core Ultra 7 356H (0.4% higher), AMD Ryzen AI 5 PRO 440 (0.4% higher), and Intel Core i7-14650HX (0.5% lower).

In Pc Building Simulator, the CPU's role is evident from the 1080p results. At Low settings, the system achieves 349 FPS, which is 165 FPS higher than at High settings. This large gap suggests that the CPU can feed the GPU faster than the GPU can render at low graphical loads. The 12 cores and 24 threads provide ample capacity for the game's simulation logic, which involves tracking multiple PC components and their interactions.

The CPU's benchmark scores support this interpretation. The Cinebench R23 multicore score of 16262 and the 3DMark max threads score of 10075 indicate strong multi-threaded performance. The single-thread Cinebench R23 score of 1527 and 3DMark single-thread score of 941 show that individual core performance is also solid. These scores suggest that the CPU will not bottleneck the GPU at any resolution tested, as evidenced by the fact that 4K frame rates are significantly lower than 1080p frame rates, indicating GPU saturation.

The CPU's 64 MB L3 cache and dual-channel DDR4 memory support with 51.2 GB/s bandwidth are sufficient for this game. The PassMark multithread score of 39002 and single-thread score of 3469 further confirm that the Ryzen 9 5900X is a high-performance part that can sustain the high frame rates observed at 1080p. The data shows that the CPU is not the limiting component in any of the measured scenarios; instead, the GPU takes over as the bottleneck at 1440p and 4K.

How This Combo Ranks

The AMD Ryzen 9 5900X with NVIDIA GeForce RTX 4070 ranks 921st out of 3723 tested combos for Pc Building Simulator.
