# Pc Building Simulator with AMD Ryzen 5 5600G + NVIDIA GeForce RTX 5090

Pc Building Simulator is a simulation title that scales unusually well with raw hardware, and the combination of AMD's 6-core Ryzen 5 5600G with NVIDIA's flagship RTX 5090 produces results that are heavily GPU-bound at higher resolutions yet increasingly CPU-limited at 1080p. The measured data shows this pairing delivers playable frame rates across all tested settings, with the RTX 5090's 32 GB of GDDR7 memory and 104.8 TFLOPS FP32 compute providing massive headroom that the 5600G's Zen 3 architecture cannot always fully utilize.

FAQ

Q: Is the Ryzen 5 5600G a bottleneck for the RTX 5090 in this game?

A: At 1080p, yes—the frame rate gap between Low and Ultra settings is only 319.5 to 242.8 FPS, which is a 24% spread, suggesting the CPU limits performance before the GPU can stretch its legs. At 4K, the spread widens dramatically (177.1 Low vs 84.4 Ultra, a 52% difference), indicating the GPU becomes the primary constraint.

Q: How does this combo rank against other tested combinations?

A: The combo ranks 89th out of 1,769 tested combinations in Pc Building Simulator, placing it in the top 5% of all pairings. This is a strong result given the CPU's mid-range positioning, though the ranking reflects the GPU's dominance in this title.

Q: What is the best settings preset for smooth gameplay at 4K?

A: High settings at 4K deliver 87.1 FPS average, which is the best balance between visual quality and frame rate. Ultra drops to 84.4 FPS (a 3% reduction), while Medium hits 124.1 FPS—both playable, but High offers the sweet spot for quality-per-frame.

Q: Does the RTX 5090's 32 GB VRAM matter in this game?

A: The data indicates the 32 GB GDDR7 buffer is more than sufficient, as performance scales consistently with resolution without any signs of VRAM-related stutter or frame drops. The 1.79 TB/s bandwidth provides ample headroom for texture-heavy simulation scenes.

Q: How does the 5600G's single-thread performance affect results?

A: The CPU's 3dmark single-thread score of 872 and Cinebench R23 single-core score of 2,365 suggest adequate per-core performance, but the 1080p results show it becomes the limiting factor. The 6-core/12-thread configuration with a 3.90 GHz base and 4.40 GHz boost provides enough throughput for this simulation, but not enough to fully saturate the RTX 5090.

Q: Is this a balanced pairing for 1440p gaming?

A: At 2560x1440, the combo delivers 172.4 FPS on High and 164.8 FPS on Ultra, showing strong performance with reasonable scaling between presets. This resolution appears to be where the CPU and GPU reach a more balanced state, with the 5600G keeping pace adequately.

Settings Recommendations

The measured data presents a clear hierarchy: Ultra settings provide the highest visual fidelity but cost significant frame rate at every resolution. At 1080p, the difference between Ultra (242.8 FPS) and High (247 FPS) is negligible—less than 2%—so High is the recommended preset for this resolution to save GPU resources without sacrificing visible quality. At 1440p, the gap widens slightly: High (172.4 FPS) beats Ultra (164.8 FPS) by 4.6%, but both remain far above playable thresholds. The real decision comes at 4K, where Ultra (84.4 FPS) and High (87.1 FPS) are both playable, but High offers a 3.2% improvement while likely reducing GPU temperature and power draw. Medium settings provide a substantial FPS boost at every resolution (124.1 at 4K, 238.5 at 1440p, 280.6 at 1080p) but compromise visual detail for headroom that most displays cannot even show—only 240 Hz monitors would benefit at 1080p Medium. Low settings are unnecessary for this pairing, as even 4K Ultra maintains 84.4 FPS, well above the 60 FPS standard for smooth simulation gameplay. For the best experience, High at 4K (87.1 FPS) or Ultra at 1440p (164.8 FPS) are the optimal choices depending on display resolution.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals a classic GPU-bound curve at higher resolutions. At Ultra settings, the drop from 1080p (242.8 FPS) to 1440p (164.8 FPS) represents a 32% reduction, and further down to 4K (84.4 FPS) is another 49% reduction—totaling a 65% loss from 1080p to 4K. This steep decline indicates the RTX 5090 is being pushed progressively harder as pixel count increases. However, the Low preset tells a different story: 1080p Low (319.5 FPS) to 1440p Low (276.4 FPS) is only a 13% drop, but 1440p to 4K Low (177.1 FPS) is a 36% decline. The smaller 1080p-to-1440p gap at Low settings suggests the CPU is limiting performance at lower resolutions—the 5600G cannot feed frames fast enough to utilize the GPU fully. At 4K, the GPU becomes the bottleneck regardless of settings, as evidenced by the wider spread between Low (177.1 FPS) and Ultra (84.4 FPS) at that resolution. The data indicates this game is heavily GPU-dependent at 4K, but at 1080p the 5600G's 16 MB L3 cache and dual-channel DDR4 memory bandwidth (51.2 GB/s) constrain throughput.

How This Combo Ranks

With a combo rank of 89 out of 1,769 tested combinations, this pairing places in the 95th percentile of all CPU-GPU combos tested in Pc Building Simulator. This ranking reflects the RTX 5090's massive contribution—the GPU sits in the 94th percentile among all GPUs, with an average benchmark score of 84,306. The CPU, meanwhile, ranks in the 78th percentile among all CPUs with an average score of 19,983. The combination of a top-6% GPU with a mid-upper-range CPU produces a result that exceeds what either component would achieve alone. Notably, the GPU's nearest rivals (RTX 5090 D at +0.1%, RTX 5050 Mobile at +0.2%, Radeon PRO W6600 at +1.3%, CMP 40HX at -1.6%) are all within a 3% margin, showing how tightly clustered top-tier GPUs are in synthetic benchmarks. The CPU's rivals (i7-11600H at +0.2%, i7-11800H at -0.2%, EPYC 7713P at -0.2%, Threadripper PRO 5995WX at +0.3%) similarly show that the 5600G sits in a dense performance band. The ranking of 89th overall suggests that while the GPU carries the load, the CPU's mid-range standing prevents this combo from breaking into the top 50 pairs.

GPU Role

The RTX 5090's specifications dominate this pairing's performance profile. With a boost clock of 2407 MHz, 21,760 shading units, and 176 ROPs, the GPU delivers a pixel rate of 423.6 GPixel/s and a texture rate of 1,636.8 GTexel/s. The 32 GB of GDDR7 memory on a 512-bit bus provides 1.79 TB/s of bandwidth, which is critical for a simulation game that may load many assets. The FP32 throughput of 104.8 TFLOPS (with FP16 at 1:1 ratio) gives the GPU enormous compute headroom. In the measured results, the GPU's role is most apparent at 4K, where it maintains 84.4 FPS on Ultra despite the 5600G's modest 16 MB L3 cache. The 170 RT cores and 680 tensor cores support DirectX 12 Ultimate features, though the game's simulation nature likely relies more on standard rasterization. The GPU's 94th percentile ranking (average score 84,306) versus the CPU's 78th percentile (19,983) shows the performance mismatch, yet the measured FPS numbers remain excellent because the RTX 5090 can brute-force through most scenes. The 575 W TDP and 950 W suggested PSU indicate this is a power-hungry solution, but the performance data justifies the thermal and electrical demands for 4K gaming.

Measured FPS Breakdown

1080p (1920x1080):

• Low: 319.5 FPS average
• Medium: 280.6 FPS average
• High: 247 FPS average
• Ultra: 242.8 FPS average

At 1080p, the CPU limits performance—the gap between Low and Medium is 12%, but Medium to High is 12% again, while High to Ultra is only 1.7%. The 319.5 FPS ceiling at Low shows the 5600G's maximum frame generation capability.

1440p (2560x1440):

• Low: 276.4 FPS average
• Medium: 238.5 FPS average
• High: 172.4 FPS average
• Ultra: 164.8 FPS average

The 1440p results show a more pronounced GPU influence: Low to Medium drops 14%, Medium to High drops 28%, and High to Ultra drops 4.4%. The 276.4 FPS at Low still exceeds any 1440p display's refresh rate.

4K (3840x2160):

• Low: 177.1 FPS average
• Medium: 124.1 FPS average
• High: 87.1 FPS average
• Ultra: 84.4 FPS average

At 4K, the GPU becomes the clear bottleneck: Low to Medium drops 30%, Medium to High drops 30%, and High to Ultra drops 3.1%. The 84.4 FPS at Ultra is above the 60 FPS standard, while Low's 177.1 FPS shows the RTX 5090's raw power even at 4K. The consistent ~30% drops between Low-Medium-High at 4K indicate the game's settings have compounding effects on GPU load.
