# Pc Building Simulator with AMD Ryzen 9 7900X + NVIDIA GeForce RTX 3080

The combination of the AMD Ryzen 9 7900X and NVIDIA GeForce RTX 3080 delivers a fascinating performance profile in Pc Building Simulator, a simulation title that scales dramatically with resolution and settings. The measured data reveals a system that excels at high refresh rates at 1440p but begins to show its limits when pushed to 4K Ultra, with the CPU showing exceptional headroom while the GPU becomes the primary constraint at higher resolutions. This analysis examines the measured frame rates across three resolutions and four quality presets, interpreting what the data reveals about the balance between the 12-core Zen 4 processor and the Ampere-based graphics card.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial, revealing a classic GPU-bound scenario at higher resolutions. At High settings, the average frame rate falls from 176 FPS at 1920x1080 to 111 FPS at 2560x1440, then to 58 FPS at 3840x2160. This represents a 37% decrease when moving from 1080p to 1440p, and a 48% further drop when moving from 1440p to 4K. The scaling pattern indicates that the RTX 3080's rendering throughput is the limiting factor at higher pixel counts, while the CPU has ample headroom to feed the GPU at lower resolutions.

The trend becomes even more pronounced when examining Low settings, where the frame rate at 1080p reaches 352 FPS but drops to 222 FPS at 1440p and 116 FPS at 4K. The 4K result at Low settings is still higher than the 1080p result at Ultra settings (168 FPS), suggesting that the GPU's raw pixel-pushing capability is the dominant variable. The resolution scaling from 1440p to 4K at Low settings shows a 48% reduction, nearly identical to the proportional drop seen at High settings, reinforcing that the RTX 3080's memory bandwidth and shading throughput are the constraining factors at 4K.

Interestingly, the gap between 1080p and 1440p is proportionally smaller at higher settings. At Ultra, the drop from 168 FPS to 106 FPS represents a 37% reduction, while at Low settings the drop from 352 FPS to 222 FPS is also 37%. This consistent scaling suggests the game's workload is well-balanced across the GPU's compute units, with no single bottleneck emerging until the 4K resolution boundary. The data indicates that this system is best suited for 1440p gaming, where it maintains high frame rates even at Ultra settings, while 4K requires dropping to Medium settings to achieve playable performance above 60 FPS.

GPU Role

The NVIDIA GeForce RTX 3080, built on the Ampere architecture with 10 GB of GDDR6X memory on a 320-bit bus, demonstrates its capabilities through the measured results. The GPU's memory bandwidth of 760.3 GB/s plays a crucial role in the 4K results, where the 58 FPS average at High settings and 55 FPS at Ultra suggest that the 10 GB memory capacity is sufficient but the bandwidth becomes a limiting factor at higher resolutions. The GPU's boost clock of 1710 MHz and base clock of 1440 MHz provide the computational foundation for the 29.77 TFLOPS of FP32 performance, which translates to the observed frame rates across all settings.

The GPU's 8704 shading units and 272 texture mapping units are directly reflected in the scaling between settings at each resolution. At 4K, the jump from Low (116 FPS) to Medium (82 FPS) represents a 29% performance cost, while the jump from Medium to High (58 FPS) costs another 29%. This consistent incremental penalty suggests the game's visual effects at each preset level place proportional demands on the GPU's compute resources. The RTX 3080's 68 RT cores and 272 tensor cores, while not explicitly tested in this game's measured data, contribute to the overall architecture that handles the simulation's rendering workload.

Comparing to its nearest rivals in the GPU benchmark database, the RTX 3080's average benchmark score of 23172 places it just 0.3% below the NVIDIA P106-100 and 0.3% below the AMD Radeon Pro Vega 16, with similar margins to the AMD Radeon RX 6600M and Radeon R9 M290X. These very small deltas (all within 0.4%) indicate that the RTX 3080's raw compute performance is closely matched by those cards in synthetic benchmarks, though the measured FPS in this game demonstrates the real-world advantage of its higher memory bandwidth and shading throughput. The GPU's 68th percentile ranking among all GPUs suggests it sits in the upper-middle tier of graphics cards, which aligns with the observed performance that delivers excellent 1440p results but struggles to maintain 60 FPS at 4K Ultra.

CPU Role

The AMD Ryzen 9 7900X provides exceptional processing headroom in this simulation title, as evidenced by the massive frame rates achieved at lower resolutions. With 12 cores and 24 threads based on the Zen 4 architecture, this CPU delivers a Cinebench R23 multi-core score of 29300 and a single-core score of 2016.5, along with a Geekbench multi-core score of 19267 and single-core score of 2617. These synthetic benchmarks suggest the CPU can easily handle the simulation logic and physics calculations required by Pc Building Simulator, which is confirmed by the 352 FPS result at 1080p Low settings.

The CPU's boost clock of 5.60 GHz and base clock of 4.70 GHz provide the single-thread performance necessary for game logic, while the 64 MB of shared L3 cache and 1 MB L2 cache per core help reduce memory latency. The 83.2 GB/s of memory bandwidth available through the dual-channel DDR5 support ensures the CPU can quickly feed data to the GPU. The 5 nm process node from TSMC, with 13,140 million transistors across a 2x 71 mm² die, contributes to the CPU's efficiency in maintaining high clock speeds under load.

When comparing to its nearest rivals, the Ryzen 9 7900X's average benchmark score of 53288 places it just 0.2% above the AMD EPYC 7313P and 0.6% above the Intel Xeon 634, while it sits 0.3% below the Intel Xeon Phi 7290 and 0.6% below the Intel Core i7-14700F. These tight margins in synthetic benchmarks suggest the 7900X is competitively positioned, but its real advantage in this game appears to be its ability to maintain high minimum frame rates, as evidenced by the 134 FPS minimum at 1440p Medium and 212 FPS minimum at 1080p Medium. The CPU's 91st percentile ranking among all CPUs indicates it has substantial headroom that is not fully utilized at 4K resolutions, where the GPU becomes the bottleneck.

The overall ranking of 1022 out of 3723 indicates that while this is not a top-tier combination, it outperforms the majority of tested systems, making it a solid choice for this game at 1440p.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest performance across all settings. Low settings produce an average of 352 FPS, Medium settings produce 249 FPS with a minimum of 212 FPS and maximum of 287 FPS, High settings produce 176 FPS, and Ultra settings produce 168 FPS. The difference between High and Ultra at this resolution is minimal at just 8 FPS, suggesting that the Ultra preset adds visual effects that have a negligible performance cost at 1080p given the GPU's capabilities.

At 2560x1440, the performance remains strong but shows the GPU beginning to work harder. Low settings average 222 FPS, Medium settings average 157 FPS with a range of 134 to 181 FPS, High settings average 111 FPS, and Ultra settings average 106 FPS. The gap between High and Ultra remains tight at 5 FPS, while the jump from Low to Medium costs 65 FPS, representing a 29% performance reduction. The minimum frame rate of 134 FPS at Medium settings demonstrates the system's ability to maintain smooth gameplay even during demanding scenes.

At 3840x2160, the GPU becomes the clear limiting factor. Low settings average 116 FPS, Medium settings average 82 FPS with a range of 70 to 95 FPS, High settings average 58 FPS, and Ultra settings average 55 FPS. The drop from Medium to High is 24 FPS (29% reduction), while the drop from High to Ultra is just 3 FPS, indicating that the Ultra preset's additional effects are relatively lightweight compared to the rendering load at 4K. The minimum frame rate of 70 FPS at Medium settings shows that 4K Medium is the most demanding configuration that still maintains consistently smooth performance above 60 FPS.

Settings Recommendations

Based on the measured data, the optimal settings depend heavily on the target resolution. At 1920x1080, Ultra settings are clearly recommended, as the 168 FPS average provides an excellent experience that maximizes visual quality without any meaningful performance compromise. The system has so much headroom at this resolution that even the most demanding preset delivers frame rates well above typical high-refresh-rate displays.

At 2560x1440, Ultra settings are also recommended, with the 106 FPS average providing a smooth experience on most monitors. The small 5 FPS gap between High and Ultra settings makes Ultra the obvious choice for maximizing visual fidelity. For users with 144 Hz or higher refresh rate displays, Medium settings at 157 FPS may be preferable to ensure the frame rate consistently exceeds the display's refresh rate, as the 134 FPS minimum at Medium provides a larger safety margin.

At 3840x2160, Medium settings provide the best balance of visual quality and performance, with an average of 82 FPS and a minimum of 70 FPS. This configuration ensures smooth gameplay above 60 FPS while maintaining reasonable visual fidelity. High settings at 58 FPS and Ultra at 55 FPS are borderline playable but risk dropping below 60 FPS during demanding scenes, making them acceptable only for users who prioritize visual quality over frame rate consistency. Low settings at 116 FPS are unnecessary given the Medium preset's strong performance, and the visual quality reduction is not justified when Medium already delivers such a high frame rate. The data shows that the RTX 3080's 10 GB memory configuration is well-suited to 1440p Ultra, while 4K gaming requires the compromise of Medium settings to achieve a consistently smooth experience.
