# Pc Building Simulator with AMD Ryzen 9 7900X + AMD Radeon RX 7600 XT

Pc Building Simulator, a simulation title released in 2019, presents a unique workload that combines CPU-driven logic with GPU-accelerated rendering. The pairing of the 12-core AMD Ryzen 9 7900X with the AMD Radeon RX 7600 XT produces a distinctive performance profile across resolutions. The measured data indicates this combo ranks 1131st out of 1769 tested combinations in this game, placing it in the lower-middle portion of the field. This ranking, combined with the FPS trajectory from 1080p to 4K, reveals a system that is heavily GPU-limited at higher resolutions but shows surprising CPU headroom at lower settings.

Resolution Scaling

The FPS drop from 1080p to 4K is dramatic and tells a clear story about system balance. At Low settings, the average frame rate falls from 234.8 FPS at 1920x1080 to 146.8 FPS at 2560x1440, then plummets to 76.4 FPS at 3840x2160. This represents a 67.5% reduction in performance from 1080p to 4K at Low settings, indicating that the RX 7600 XT's rendering pipeline becomes the dominant constraint as pixel count increases.

The scaling pattern shifts with quality presets. At High settings, the drop from 119.7 FPS at 1080p to 75.9 FPS at 1440p to 38.4 FPS at 4K shows a more linear degradation. The Ultra preset tells a similar story: 109.6 FPS at 1080p, 68.8 FPS at 1440p, and 38 FPS at 4K. Notably, the difference between High and Ultra at 4K is negligible—only 0.4 FPS—suggesting that at 4K, the GPU is saturated regardless of whether High or Ultra settings are selected. The gap between Low and Ultra at 4K is 38.4 FPS, whereas at 1080p that same gap is much larger at 125.2 FPS, further confirming that resolution scaling compresses the performance envelope as the GPU becomes the bottleneck.

The data shows that at 1080p, the system has substantial headroom. The jump from Low to Medium costs 71.5 FPS, while Medium to Ultra costs 53.7 FPS. This non-linear scaling suggests the CPU can feed frames quickly at lower resolutions, but the GPU's shading units, TMUs, and ROPs begin to limit throughput as settings increase. At 1440p, the same pattern holds but with reduced absolute values: Low delivers 146.8 FPS, Medium 106.2 FPS, High 75.9 FPS, and Ultra 68.8 FPS. The 4K results—76.4 FPS Low, 57.1 FPS Medium, 38.4 FPS High, and 38 FPS Ultra—show that only the Low preset approaches playable smoothness, while Ultra falls below 40 FPS.

How This Combo Ranks

The combo rank of 1131 out of 1769 places this configuration in the 36th percentile of all tested combinations for Pc Building Simulator. This is a surprisingly low ranking given the hardware involved, but it reflects the game's specific demands. The CPU is not the limiting factor here—the Ryzen 9 7900X sits in the 93rd percentile against all CPUs, with an average benchmark score of 50556. Its nearest rivals include the Intel Core Ultra 5 235 (50598, -0.1% delta), AMD Ryzen 9 5900XT (50738, -0.4% delta), Intel Core i7-13850HX (50827, -0.5% delta), and Intel Core i9-13980HX (50944, -0.8% delta). All four rivals score within 1% of the 7900X, indicating that CPU performance is not differentiating this combo in the rankings.

The GPU tells a different story. The RX 7600 XT ranks in the 63rd percentile against all GPUs with an average benchmark score of 20146. Its nearest rivals are the AMD Radeon RX 460 (20088, +0.3% delta), AMD Radeon RX 7600 (20258, -0.6% delta), NVIDIA GeForce RTX 2060 SUPER (19774, +1.9% delta), and NVIDIA GeForce RTX 3070 Mobile (20534, -1.9% delta). The fact that this GPU is bracketed by a much older RX 460 and a mobile RTX 3070 demonstrates its mid-range positioning. In Pc Building Simulator, the GPU's 16 GB of GDDR6 memory and 288.0 GB/s bandwidth are sufficient for the game's asset loading, but the 2048 shading units and 64 ROPs struggle with the simulation's rendering workload, particularly at higher resolutions.

The delta between the combo's rank and the CPU's percentile suggests that many other combinations in the database pair stronger GPUs with comparable or lesser CPUs, achieving better results in this game. The 1769-combo field includes configurations that likely feature higher-tier GPUs, which would explain why a 93rd-percentile CPU paired with a 63rd-percentile GPU lands in the bottom half of the rankings.

Measured FPS Breakdown

At 1920x1080, the system delivers its best results. Low settings produce 234.8 FPS, which is more than double the High preset's 119.7 FPS. Medium settings yield 163.3 FPS, and Ultra drops to 109.6 FPS. The spread from Low to Ultra is 125.2 FPS, showing significant settings sensitivity. The step from Low to Medium costs 71.5 FPS, while Medium to High costs 43.6 FPS, and High to Ultra costs 10.1 FPS. This pattern indicates diminishing returns as settings increase, with the largest performance hit occurring between Low and Medium.

At 2560x1440, the absolute numbers drop but the pattern remains. Low settings achieve 146.8 FPS, which is 62.5% of the 1080p Low result. Medium delivers 106.2 FPS, High reaches 75.9 FPS, and Ultra produces 68.8 FPS. The Low-to-Ultra spread narrows to 78 FPS. The transition from Low to Medium costs 40.6 FPS, Medium to High costs 30.3 FPS, and High to Ultra costs 7.1 FPS. The gap between High and Ultra shrinks to 7.1 FPS, suggesting that at 1440p, the GPU begins to saturate at High settings.

At 3840x2160, the performance collapses. Low settings deliver 76.4 FPS, which is barely above the 1440p High result. Medium produces 57.1 FPS, High drops to 38.4 FPS, and Ultra matches at 38 FPS. The Low-to-Ultra spread is only 38.4 FPS. The step from Low to Medium costs 19.3 FPS, Medium to High costs 18.7 FPS, and High to Ultra costs 0.4 FPS. At 4K, the GPU is the sole limiting factor—increasing settings from High to Ultra has virtually no effect, while the difference between Low and Medium remains significant.

CPU Role

The AMD Ryzen 9 7900X is a 12-core, 24-thread processor built on the Zen 4 architecture (codename Raphael) using a 5 nm process from TSMC. It operates on the AMD Socket AM5 platform with a base clock of 4.70 GHz and a boost clock of 5.60 GHz. The CPU supports DDR5 memory in dual-channel configuration with 83.2 GB/s bandwidth and includes 64 MB of shared L3 cache, with 1 MB L2 and 64 KB L1 per core. The 170 W TDP and unlocked multiplier indicate a high-end desktop part, though its integrated Radeon Graphics are secondary to the discrete RX 7600 XT.

In synthetic benchmarks, the 7900X demonstrates strong multi-threaded performance. Its Cinebench R23 multicore score is 43695, while single-core reaches 6168. Geekbench shows 17830 multicore and 2952 single-core. The 3DMark results scale from 1093 single-thread to 12536 max-threads, with 16-thread scoring 10972. Passmark multithread reaches 51406, with integer math at 169273 and floating-point math at 103952. These figures place the CPU in the 93rd percentile, with an average benchmark score of 50556.

In Pc Building Simulator, the CPU's role is evident from the resolution scaling data. At 1080p Low, the system produces 234.8 FPS, which approaches the CPU's frame-feeding limit. However, the fact that the combo ranks 1131st out of 1769 suggests that the GPU is the primary constraint. The 12 cores and 24 threads are largely underutilized in this simulation, as evidenced by the minimal delta (under 1%) between the 7900X and its nearest rivals. The CPU's 5.60 GHz boost clock and 64 MB L3 cache provide ample single-thread performance, but the RX 7600 XT's 22.57 TFLOPS FP32 throughput and 176.3 GPixel/s pixel rate cannot keep pace with the CPU's output at higher resolutions. The data indicates that swapping the GPU for a higher-tier model would yield larger FPS gains than any CPU change within this performance class.
