Pc Building Simulator

Pc Building Simulator presents an unusual benchmark scenario: it is a simulation title where the primary workload is CPU-driven logic and UI rendering, yet the data shows this AMD Ryzen 7 5700X and NVIDIA GeForce RTX 4080 SUPER pairing delivers frame rates that scale dramatically with resolution and settings. The measured results reveal a system that is overwhelmingly GPU-limited at 4K, but which transitions into a CPU-bound regime as resolution drops and settings are lowered, making it a fascinating case study in component balance.

Resolution Scaling

The frame rate progression from 1080p to 4K demonstrates a classic GPU-bound curve, but with an unusual twist at the high end. At 1080p with Low settings, the combo produces 340.4 FPS, which drops to 291.8 FPS at 1440p and then falls sharply to 154.6 FPS at 4K. This represents a 54.6% reduction in performance from 1080p to 4K at Low settings, indicating that the RTX 4080 SUPER is the dominant bottleneck at higher resolutions. However, the scaling is not uniform across settings. At Ultra settings, the drop is much less severe: 223.6 FPS at 1080p, 142.5 FPS at 1440p, and 72.8 FPS at 4K. The 1080p-to-4K delta at Ultra is 67.4%, which is steeper than the Low settings delta, suggesting that the higher-quality presets introduce additional shading and memory pressure that amplify the GPU workload.

The intermediate resolutions reveal where the balance shifts. At 1440p High, the system produces 147.3 FPS, while at 1080p High it reaches 235 FPS. The 1440p-to-1080p gain of 59.5% suggests that the CPU is beginning to assert itself at lower resolutions, as the GPU has more headroom to render frames quickly. This becomes more evident at Low settings: 291.8 FPS at 1440p versus 340.4 FPS at 1080p yields only a 16.7% improvement, a modest gain that points to the Ryzen 7 5700X's 8 cores and 16 threads becoming a limiting factor. At 4K, the GPU is clearly the constraint, as even the jump from Medium (108.8 FPS) to Low (154.6 FPS) produces a 42.1% uplift, far exceeding the CPU's ability to feed frames at lower resolutions.

GPU Role

The RTX 4080 SUPER's specifications align closely with the observed 4K performance characteristics. With 16 GB of GDDR6X memory on a 256-bit bus and 736.3 GB/s of bandwidth, the card has ample memory capacity for Pc Building Simulator's asset streaming, but the bandwidth is the more critical factor at high resolutions. The 4K Ultra result of 72.8 FPS and 4K High of 79.2 FPS show that the card is being pushed to its limits, with the 8.8% difference between these two presets indicating that Ultra settings impose a meaningful shader and texture overhead. The GPU's 10,240 shading units and 112 ROPs provide the raw compute necessary for these frame rates, while the 80 RT cores and 320 tensor cores are largely idle in this simulation title, as the game does not leverage ray tracing or DLSS.

The measured data suggests that the card's memory subsystem is a key differentiator. At 4K Medium, the system achieves 108.8 FPS, which is 36.8% higher than 4K High, showing that the 16 GB frame buffer is not a constraint but rather the shader complexity is. The GPU's boost clock of 2550 MHz and base clock of 2295 MHz are typical for the Ada Lovelace architecture, and the benchmark results indicate they are sufficient to maintain consistent performance across the resolution range. In synthetic benchmarks, the card scores 34,245 in Passmark G3D and 24,6994 in Geekbench OpenCL, placing it in the 88th percentile of all GPUs. Its nearest rival, the AMD Radeon RX 6900 XT, scores 53,489 on average, a mere 0.2% delta, which suggests that in this game, the RTX 4080 SUPER's lead is marginal at best, as the simulation's workload does not heavily tax the GPU's advanced features.

CPU Role

The Ryzen 7 5700X's contribution becomes apparent when examining the lower-resolution results. At 1080p Low, the system produces 340.4 FPS, but this is only 16.7% higher than the 1440p Low result of 291.8 FPS, a small gain that indicates the CPU is nearing its throughput ceiling. The CPU's 8 cores and 16 threads, based on the Zen 3 architecture, are well-suited for Pc Building Simulator's simulation logic, which involves tracking component compatibility, power draw, and system temperatures. The 32 MB of shared L3 cache helps maintain low latency for these calculations, and the 4.60 GHz boost clock ensures responsive single-threaded performance, as evidenced by a 3DMark single-thread score of 921 and a Cinebench R23 single-core score of 3,193.

The CPU's multithreaded capabilities are more relevant for background tasks and physics calculations. The Cinebench R23 multicore score of 22,620 and Passmark multithread score of 26,612 show strong scaling across the 16 threads, but the game's frame rates at 1080p Ultra (223.6 FPS) versus 1080p High (235 FPS) reveal a 4.9% difference, suggesting that the CPU is not the primary limiter even at lower resolutions. However, the 1080p Low result of 340.4 FPS is telling: it is only 14.9% higher than 1080p Medium (301 FPS), which indicates that the CPU's ability to process game logic becomes a bottleneck when the GPU is not heavily loaded. The CPU's 65 W TDP and 7 nm process node allow for sustained boost clocks without thermal throttling, which is critical for maintaining these high frame rates over extended sessions.

How This Combo Ranks

Among the 1,769 tested combinations in Pc Building Simulator, this pairing of the Ryzen 7 5700X and RTX 4080 SUPER ranks 141st, placing it in the top 8% of all configurations. This ranking is notable because the CPU is not a top-tier part; it sits in the 83rd percentile of all CPUs, with an average benchmark score of 26,214. Its nearest rivals include the Intel Core i9-11900KF (26,196, delta 0.1%), AMD Ryzen 5 7600X (26,272, delta -0.2%), and AMD Ryzen 7 PRO 6850U (26,262, delta -0.2%), showing that the 5700X is competitive with parts from newer generations. The GPU, meanwhile, is in the 88th percentile of all GPUs, with an average score of 53,610, and its nearest rival is the AMD Radeon RX 6900 XT at 53,489 (delta 0.2%).

The combination's high rank relative to its component percentiles suggests that Pc Building Simulator rewards the specific balance of this CPU and GPU. The 141st position out of 1,769 means that only 140 other combinations produce higher average frame rates across all tested scenarios. This is a strong result for a CPU that was released in April 2022 with a launch MSRP of $299, especially when paired with a GPU that has a launch MSRP of 999 USD. The data indicates that the RTX 4080 SUPER's high bandwidth and shading power compensate for the CPU's mid-range positioning, allowing the system to excel in a game that is not traditionally considered a GPU stress test.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates, with Low settings producing 340.4 FPS, Medium reaching 301 FPS, High achieving 235 FPS, and Ultra hitting 223.6 FPS. The gap between Low and Medium is 39.4 FPS, while the gap between High and Ultra is only 11.4 FPS, indicating diminishing returns as settings increase. The 1080p results show a clear CPU influence, as the frame rates are well above what the GPU alone would cap at, but the scaling from Low to Ultra (a 34.3% reduction) reflects the GPU's increasing workload.

Moving to 2560x1440, the frame rates remain high but show a more pronounced GPU impact. Low settings produce 291.8 FPS, Medium drops to 209.9 FPS, High falls to 147.3 FPS, and Ultra reaches 142.5 FPS. The 1440p Ultra result is 36.3% lower than the 1080p Ultra result, while the 1440p Low result is 14.3% lower than 1080p Low. This differential highlights how the GPU becomes more dominant at higher resolutions, as the pixel count increases from 2.07 million to 3.69 million, a 78% increase that directly impacts the rasterization workload.

At 3840x2160, the GPU is clearly the limiting component. Low settings yield 154.6 FPS, Medium drops to 108.8 FPS, High falls to 79.2 FPS, and Ultra bottoms out at 72.8 FPS. The 4K Low result is still quite playable, but the 4K Ultra result shows a 52.9% reduction from the 1080p Ultra score. The progression from Low to Ultra at 4K (a 112.4% reduction) is steeper than at 1080p (34.3%), confirming that the RTX 4080 SUPER's 52.22 TFLOPS of FP32 compute is the primary driver of performance at this resolution. The 4K Medium result of 108.8 FPS represents a sweet spot for visual quality and performance, as it is 37.6% higher than 4K High and 49.5% higher than 4K Ultra.
