Pc Building Simulator

The pairing of AMD’s Ryzen 5 5600 with NVIDIA’s GeForce RTX 4090 in Pc Building Simulator produces an unusual bottleneck dynamic. While the RTX 4090 is a flagship-class GPU with 24 GB of GDDR6X memory and a 1.01 TB/s memory bandwidth, the Ryzen 5 5600 is a 6-core, 12-thread Zen 3 part with a 4.40 GHz boost clock. The measured frame rates reveal that this simulation title is heavily dependent on the CPU’s single-thread performance, yet the GPU’s raw power still dominates at higher resolutions. The data shows a clear pattern: at 1080p, the CPU becomes the limiting factor, while at 4K, the GPU’s workload increases enough to shift the balance. This analysis breaks down the measured FPS across resolutions and settings, contextualizes the combo’s rank among 1769 tested configurations, and explains the GPU’s role in this specific title.

Resolution Scaling

The FPS drop from 1080p to 4K is stark and reveals a classic CPU-bound scenario at lower resolutions. At 1080p with Low settings, the combo achieves 331.1 FPS, but this falls to 284.5 FPS at 1440p and 171.7 FPS at 4K. The percentage decline from 1080p to 4K at Low settings is approximately 48% — a massive reduction that indicates the RTX 4090 is being held back by the Ryzen 5 5600 at 1080p. The CPU’s 3.50 GHz base clock and 4.40 GHz boost clock, combined with 32 MB of shared L3 cache, simply cannot feed the GPU enough frames at lower resolutions where the GPU is underutilized.

At Ultra settings, the pattern shifts. The 1080p Ultra result is 245.5 FPS, dropping to 158.6 FPS at 1440p and 81.9 FPS at 4K. The 4K Ultra score is only 33% of the 1080p Ultra score, showing that the GPU is now the dominant constraint. This is expected: the RTX 4090’s 16384 shading units and 82.58 TFLOPS FP32 performance are being fully exercised at 4K, while the CPU has more time to prepare frames. The gap between Low and Ultra at 4K is also telling — 171.7 FPS versus 81.9 FPS — a 52% performance drop purely from settings, which confirms that the GPU’s rendering workload scales dramatically with visual fidelity.

Interestingly, the 1440p results show a middle ground. At High settings, 1440p delivers 166.5 FPS, which is 65% of the 1080p High score of 255.6 FPS. This suggests that 1440p is where the CPU and GPU reach a more balanced state, though the CPU still exerts some influence. The 1080p to 1440p drop at High settings is 89.1 FPS, while the 1440p to 4K drop is 79.2 FPS — nearly identical absolute reductions, implying that the game’s engine scales resolution in a linear fashion once the CPU bottleneck is mitigated. For a simulation game focused on PC building, these numbers indicate that the RTX 4090 is overkill for 1080p but becomes a necessary component for smooth 4K Ultra play.

FAQ

*Q: What is the highest average FPS achieved by this combo in Pc Building Simulator?*

A: The highest measured average FPS is 331.1, achieved at 1920x1080 resolution with Low settings. This drops to 284.5 FPS at 2560x1440 Low and 171.7 FPS at 3840x2160 Low.

Q: Does the RTX 4090’s 24 GB VRAM make a difference in this game?

A: The 24 GB GDDR6X memory with 1.01 TB/s bandwidth is far more than Pc Building Simulator requires, as evidenced by the FPS scaling. At 4K Ultra, the combo still delivers 81.9 FPS, suggesting that VRAM capacity is not a limiting factor at any tested setting.

Q: How does the Ryzen 5 5600’s single-thread performance affect results?

A: The CPU’s 3DMark single-thread score of 882 and Cinebench R23 single-core score of 2584 indicate strong per-core performance. However, at 1080p, the 331.1 FPS Low result versus 245.5 FPS Ultra shows that the CPU cannot sustain higher frame rates, acting as the bottleneck before the GPU is fully utilized.

Q: What is the most demanding setting combination for this hardware?

A: The most demanding configuration is 3840x2160 resolution with Ultra settings, producing 81.9 FPS. This is the lowest measured average FPS and represents the point where the GPU’s 16384 shading units and 176 ROPs are working hardest.

Q: Is this combo better suited for 1440p or 4K gaming?

A: The data favors 1440p for high refresh rates, with Ultra settings hitting 158.6 FPS. At 4K Ultra, the combo manages 81.9 FPS, which is playable but not ideal for high-refresh displays. The 1440p High result of 166.5 FPS offers the best balance of fidelity and speed.

Q: How does the combo’s rank in this game compare to its overall hardware percentile?

A: The combo ranks 81st out of 1769 tested combinations in Pc Building Simulator, placing it in the top 4.6% of all combos. This is slightly below the CPU’s 79th percentile and GPU’s 91st percentile, reflecting the CPU bottleneck at lower resolutions.

GPU Role

The RTX 4090’s role in Pc Building Simulator is defined by its immense compute resources and memory subsystem. The GPU’s 16384 shading units, 512 TMUs, and 176 ROPs provide a pixel rate of 443.5 GPixel/s and a texture rate of 1,290.2 GTexel/s. These specifications translate into the ability to push 4K Ultra at 81.9 FPS, which is a demanding workload for most hardware. The 24 GB of GDDR6X memory on a 384-bit bus delivers 1.01 TB/s of bandwidth, ensuring that texture streaming and asset loading never become a bottleneck, even at 4K with high-detail settings.

The GPU’s clock behavior is also relevant. With a base clock of 2235 MHz and a boost clock of 2520 MHz, the RTX 4090 maintains high frequency under load. The memory clock runs at 1313 MHz, translating to 21 Gbps effective speed. These clocks contribute to the GPU’s 82.58 TFLOPS FP32 performance, which is critical for the simulation’s physics and rendering calculations. However, the measured FPS data shows that the GPU is not always the limiting factor. At 1080p Low, the 331.1 FPS result suggests the CPU is saturating first, as the RTX 4090’s compute capacity is underutilized.

The GPU’s 128 RT cores and 512 tensor cores are present but largely irrelevant for this title, which does not appear to use ray tracing or DLSS based on the FPS measurements. Instead, the GPU’s raw rasterization power dominates. The 4K High result of 87.3 FPS versus 4K Ultra at 81.9 FPS shows only a 6% drop, indicating that the Ultra preset’s additional effects do not heavily tax the GPU. This suggests that the RTX 4090 is overprovisioned for the game’s visual demands, and the CPU’s 6-core, 12-thread configuration with 32 MB L3 cache is the primary limiter at lower resolutions.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates across all settings. Low settings produce 331.1 FPS, Medium hits 288.1 FPS, High reaches 255.6 FPS, and Ultra bottoms out at 245.5 FPS. The spread from Low to Ultra is 85.6 FPS, which is a 26% reduction. This relatively small gap indicates that the CPU is holding performance back; even at Low settings, the Ryzen 5 5600’s maximum throughput caps the frame rate. The 1080p results show no scenario where the GPU is the limiting factor, as even the most demanding Ultra preset stays above 245 FPS.

Moving to 2560x1440, the frame rates scale down but remain high. Low settings produce 284.5 FPS, Medium drops to 233.8 FPS, High hits 166.5 FPS, and Ultra falls to 158.6 FPS. The Low-to-Ultra spread here is 125.9 FPS, a 44% reduction, showing that the GPU begins to matter more as resolution increases. The High and Ultra results are close (166.5 versus 158.6), suggesting that the CPU still exerts influence, but the GPU’s workload is growing. The 1440p Medium result of 233.8 FPS is particularly notable, as it shows that even mid-tier settings can exceed 200 FPS at this resolution.

At 3840x2160, the GPU takes over as the primary constraint. Low settings deliver 171.7 FPS, Medium drops to 124.7 FPS, High falls to 87.3 FPS, and Ultra bottoms out at 81.9 FPS. The Low-to-Ultra spread is 89.8 FPS, a 52% reduction, which is the largest percentage drop across all resolutions. This confirms that at 4K, the RTX 4090’s rendering workload dominates, and the CPU’s role diminishes. The 4K High and Ultra results (87.3 and 81.9) are within 6% of each other, indicating that the Ultra preset’s marginal visual improvements are not worth the performance cost. The 4K Low result of 171.7 FPS is still faster than most 1440p Ultra results on lesser hardware, underscoring the GPU’s raw power.

How This Combo Ranks

In Pc Building Simulator, the Ryzen 5 5600 + RTX 4090 combo ranks 81st out of 1769 tested configurations. This places it in the top 4.6% of all combos, which is a strong showing given that the game is CPU-intensive at lower resolutions. The rank is notable because the RTX 4090 is among the fastest GPUs available, but the Ryzen 5 5600 is a mid-range CPU from 2022 with a launch MSRP of $199. The combo’s performance is limited by the CPU’s 6-core, 12-thread configuration, which falls behind higher-core-count processors in multithreaded workloads.

The CPU’s nearest rivals in benchmark scores include the Intel Xeon D-1746TER with a delta of 0.6% and the AMD EPYC 9554P with a delta of -0.6%. These comparisons show that the Ryzen 5 5600’s average benchmark score of 21765 is nearly identical to server-class chips, but those chips have far more cores and threads. In gaming, however, the Ryzen 5 5600’s single-thread performance (882 in 3DMark single-thread) is what matters, and it holds up well. The GPU’s nearest rivals are the NVIDIA Tesla T4 (delta -0.4%) and Tesla P40 (delta 0.5%), which are data-center parts, not gaming GPUs. This highlights that the RTX 4090’s 66473 average benchmark score is in a class of its own for consumer hardware.

The combo’s 81st rank is driven by the fact that many other combos use faster CPUs like the Ryzen 7 or Intel Core i7 series. For example, the Intel Core i7-11700F, a rival to the Ryzen 5 5600, has an average score of 21957, which is 0.9% higher. This small CPU difference translates into meaningful FPS gains at 1080p, where the CPU is the bottleneck. At 4K, the rank would likely be much higher, as the GPU’s dominance reduces the CPU’s impact. The data suggests that for Pc Building Simulator, the ideal combo would pair the RTX 4090 with a higher-end CPU to avoid the 1080p bottleneck, but the current pairing still delivers exceptional frame rates, particularly at 1440p and 4K.
