# Pc Building Simulator with AMD Ryzen 9 7900X + NVIDIA GeForce RTX 4090

The benchmark data for Pc Building Simulator reveals an extraordinary pairing: the AMD Ryzen 9 7900X and NVIDIA GeForce RTX 4090 deliver frame rates that range from a low of 82 FPS at 4K Ultra to a staggering 426 FPS at 1080p Low. This combination sits at rank 87 out of 3,723 tested combos, placing it in the top 2.3% of all configurations tested for this simulation title. The data suggests a system that is heavily GPU-limited at higher resolutions, but at 1080p, the CPU's 12-core Zen 4 architecture becomes the more critical factor in pushing frame rates to their absolute limits.

Resolution Scaling

The measured FPS data shows a dramatic scaling pattern as resolution increases. At 1080p High, the system produces 260 FPS, which drops to 164 FPS at 1440p High — a 37% reduction — and further to 86 FPS at 4K High — a 67% reduction from the 1080p baseline. This steep decline indicates that the RTX 4090 becomes the limiting component as pixel count rises, with the GPU's rendering workload scaling almost linearly with resolution.

Looking at the Low settings, the pattern becomes even more pronounced. At 1080p Low, the system achieves 426 FPS, while 1440p Low drops to 328 FPS and 4K Low falls to 171 FPS. The 4K Low result is less than half of the 1080p Low figure, suggesting that even at minimal graphical settings, the GPU's pixel throughput at 4K acts as a hard ceiling. Interestingly, the gap between 1080p and 1440p Low (a 23% drop) is smaller than the gap between 1440p and 4K Low (a 48% drop), which points to the memory bandwidth and rasterization limits of the RTX 4090 becoming more restrictive at the highest resolution.

At Medium settings, the measured minimum and maximum FPS values provide additional insight. The 1080p Medium range spans 313 to 423 FPS, while 1440p Medium spans 197 to 267 FPS, and 4K Medium spans 103 to 140 FPS. The consistency of the frame pacing, as indicated by the min-max spread, remains relatively tight across resolutions — roughly 26% of the average at each tier. This suggests that while the overall frame rate drops with resolution, the system maintains stable performance without severe stuttering or frame-time spikes, which is particularly relevant for a simulation game where consistent physics calculations matter.

The Ultra preset data shows the sharpest resolution scaling. At 1080p Ultra, the system delivers 247 FPS, dropping to 156 FPS at 1440p Ultra (a 37% decrease) and 82 FPS at 4K Ultra (a 67% decrease from 1080p). This scaling pattern mirrors the High settings almost exactly, indicating that the additional graphical features in Ultra primarily tax the GPU rather than the CPU. The data implies that for 4K gaming, the RTX 4090 is the definitive bottleneck, while at 1080p, the Ryzen 9 7900X's 24 threads can keep the GPU fed with data, allowing frame rates to approach the monitor's refresh rate limits.

GPU Role

The NVIDIA GeForce RTX 4090 brings formidable specifications to Pc Building Simulator, with 24 GB of GDDR6X memory on a 384-bit bus delivering 1.01 TB/s of bandwidth. This memory configuration is particularly relevant for a game that involves managing virtual PC components, as texture loading and asset streaming can benefit from the large frame buffer. The GPU's base clock of 2235 MHz and boost clock of 2520 MHz, combined with 16,384 shading units, allow it to maintain high throughput even when the simulation demands complex rendering of multiple system components.

The RTX 4090's 128 ray tracing cores and 512 tensor cores are unlikely to be heavily utilized in a simulation title like Pc Building Simulator, which focuses more on 2D interfaces and 3D component models rather than cinematic lighting effects. However, the GPU's raw compute capabilities — 82.58 TFLOPS of FP32 performance — ensure that any graphical workload the game presents is handled with substantial headroom. The data supports this interpretation: at 4K Ultra, the system still maintains 82 FPS, which is well above playable thresholds, even though this is the lowest measured result.

The GPU's 176 ROPs and 512 TMUs are more relevant to the measured performance. At higher resolutions, the pixel fill rate of 443.5 GPixel/s and texture rate of 1,290.2 GTexel/s become determining factors. The scaling from 1080p to 4K reduces frame rates by roughly two-thirds across all settings, which aligns with the fourfold increase in pixel count and the GPU's ability to maintain memory bandwidth but not double its fill rate output. The RTX 4090's position at the 88th percentile among all GPUs, with an average benchmark score of 60,347, confirms its high-end status, though the nearest rival comparison shows it essentially tied with the Intel Arc Pro A60 (0% delta) and only 2.9% ahead of the AMD Radeon PRO V710 in synthetic benchmarks.

FAQ

CPU Role

The AMD Ryzen 9 7900X brings 12 cores and 24 threads based on the Zen 4 Raphael architecture, with a base clock of 4.70 GHz and a boost clock of 5.60 GHz. This 5 nm processor from TSMC, featuring 13,140 million transistors across a dual-chiplet design, delivers substantial multi-threaded performance for a simulation game that must track numerous system components and their interactions. The CPU's 64 MB of shared L3 cache and 1 MB L2 cache per core provide the fast data access needed for the game's inventory management and part compatibility calculations.

In synthetic benchmarks, the Ryzen 9 7900X scores 29,300 in Cinebench R23 multicore and 2,016.5 in single-core, with a Geekbench multicore score of 19,267 and single-core of 2,617. These results place the CPU at the 91st percentile among all processors. The PassMark multithread score of 51,406 and single-thread score of 4,238 indicate strong performance in both threaded and single-threaded workloads, which is relevant for Pc Building Simulator's mixed demands of physics simulation and UI rendering.

The measured FPS data reveals the CPU's role through the 1080p Low results. At 426 FPS, the system is likely CPU-bound, as the GPU has minimal work with Low settings. The Ryzen 9 7900X's 24 threads can handle the game's simulation logic, while its 5.60 GHz boost clock ensures low latency for single-threaded tasks like UI updates. The drop to 328 FPS at 1440p Low (a 23% decrease) indicates that the GPU begins to take on more responsibility, but the CPU still maintains high throughput. The 4K Low result of 171 FPS, which is less than half of the 1080p figure, confirms that the GPU becomes the bottleneck at higher resolutions, allowing the CPU to operate below its full potential.

The CPU's memory bandwidth of 83.2 GB/s over dual-channel DDR5, combined with its 64 MB L3 cache, supports the game's need for rapid data access when loading component models and calculating compatibility. The 170 W TDP and AM5 socket platform provide ample power delivery for sustained multi-core performance, which is essential for a simulation that may run complex background calculations. The launch MSRP of $549 positions this as a high-end desktop processor, and its benchmark scores show it competing closely with server-class chips like the AMD EPYC 7313P (0.2% delta) and Intel Xeon Phi 7290 (0.3% delta).

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates across all settings. Low settings produce 426 FPS, Medium reaches 368 FPS with a minimum of 313 and maximum of 423, High achieves 260 FPS, and Ultra manages 247 FPS. The scaling from Low to Ultra represents a 42% reduction in performance, indicating that each graphics preset tier adds a meaningful but manageable workload. The Medium settings' min-max range of 313-423 FPS shows a spread of 110 FPS, which is 30% of the average, suggesting some frame-time variability even at this resolution.

Moving to 2560x1440, the frame rates remain high but show clear GPU scaling. Low settings deliver 328 FPS, Medium produces 232 FPS with a range of 197-267 FPS, High reaches 164 FPS, and Ultra drops to 156 FPS. The reduction from 1080p to 1440p ranges from 23% at Low settings to 37% at High and Ultra, showing that the GPU's pixel processing demands grow with resolution. The Medium settings' min-max spread of 70 FPS is 30% of the average, matching the proportional variability seen at 1080p.

At 3840x2160, the system's performance becomes more moderate. Low settings still deliver 171 FPS, Medium produces 121 FPS with a range of 103-140 FPS, High achieves 86 FPS, and Ultra drops to 82 FPS. The 4K results show a 48% reduction from 1440p at Low settings, but only a 48% reduction at High settings, indicating that the GPU's memory bandwidth becomes increasingly critical as resolution rises. The Medium settings' min-max spread of 37 FPS is 31% of the average, maintaining the consistent frame pacing seen at other resolutions.

The overall trend across all resolutions shows that the RTX 4090's performance scales predictably with pixel count, with the CPU maintaining high frame rates at lower resolutions. The 4K Ultra result of 82 FPS remains comfortably above playable thresholds, and the 1080p Low result of 426 FPS demonstrates the system's capability to drive high-refresh-rate displays in this simulation title.

Settings Recommendations

Based on the measured FPS data, the High preset offers the best balance of visual quality and performance for most users. At 1080p, High delivers 260 FPS, which exceeds the refresh rate of virtually all gaming monitors. At 1440p, High produces 164 FPS, still sufficient for high-refresh-rate displays. Even at 4K, High maintains 86 FPS, providing a smooth experience for a simulation game where precise frame timing is less critical than in fast-paced shooters.

For players with 4K displays seeking maximum visual fidelity, the Ultra preset at 82 FPS is a viable option, as the 5% performance difference from High (86 FPS) is negligible. However, the data suggests that the visual improvements from Ultra over High are minimal given the small FPS impact, so High is the more efficient choice for preserving frame rate headroom. The Medium preset offers a middle ground, with 368 FPS at 1080p, 232 FPS at 1440p, and 121 FPS at 4K, but the visual downgrade from High is unlikely to be worth the additional frame rate for most players.

The Low preset, delivering 426 FPS at 1080p and 171 FPS at 4K, is only recommended for competitive play or when using extremely high-refresh-rate displays (240 Hz or higher). Given that Pc Building Simulator is a simulation game focused on system assembly and management rather than fast action, the extra frame rates from Low settings provide no tangible gameplay benefit. The data indicates that High settings at 1440p — with 164 FPS — represent the sweet spot for this combination, offering a crisp image with smooth performance that fully utilizes both the Ryzen 9 7900X's processing power and the RTX 4090's rendering capabilities.
