Pc Building Simulator

Pc Building Simulator presents an unusual bottleneck profile for the AMD Ryzen 7 3700X and NVIDIA GeForce RTX 5090 D combination. The data shows a system where the GPU's immense raw power is frequently constrained by the simulation's logic and the CPU's Zen 2 architecture. Benchmark results indicate that this pairing produces exceptionally high frame rates across all tested configurations, but the scaling behavior between resolutions and settings reveals a complex interaction between the physics-heavy workload and the graphics pipeline. The measured frames per second (FPS) values, ranging from 89 at 4K Ultra to 267 at 1080p Low, demonstrate that while the RTX 5090 D can push massive pixel throughput, the Ryzen 7 3700X's 8 cores and 16 threads are often the limiting factor in this specific title.

Resolution Scaling

The frame rate drop from 1080p to 4K is surprisingly modest, which strongly indicates a CPU-bound scenario at lower resolutions. At High settings, the average FPS moves from 206 at 1920x1080 to 177 at 2560x1440, a reduction of 29 FPS (approximately 14%). Moving further to 3840x2160, the average FPS is 94, which represents a steep 53% drop from the 1080p result. This pattern is telling: the transition from 1080p to 1440p incurs a relatively small penalty, suggesting the CPU is still the primary bottleneck at both of these resolutions. However, the jump to 4K finally allows the GPU to become the limiting factor, as the pixel fill rate and memory bandwidth demands of 3840x2160 overwhelm the CPU's ability to feed frames.

Analyzing the Low settings data reveals an even clearer picture of the CPU limitation. At 1080p Low, the system achieves 267 FPS, and at 1440p Low it reaches 229 FPS. The difference between these two is only 38 FPS, which is a 14% drop. This is nearly identical to the percentage drop seen between the same resolutions at High settings. If the GPU were the bottleneck, reducing the settings would typically create a larger gap between resolutions because the GPU would have more headroom. Instead, the consistent 14% penalty suggests that the Ryzen 7 3700X's single-threaded performance, evidenced by its Geekbench single-core score of 1593, is the limiting factor for frame generation.

The 4K to 1080p scaling at Ultra settings shows a similar trend. The average FPS at 1080p Ultra is 203, while at 4K Ultra it drops to 89. This 114 FPS difference (56% reduction) is the largest across all settings presets, which is expected given the extreme pixel count of 4K. The data indicates that at 4K, the RTX 5090 D's 32 GB of GDDR7 memory and 1.79 TB/s bandwidth are being utilized more fully, but even then, the game engine's simulation logic prevents the GPU from reaching its full potential. The fact that the 4K High result (94 FPS) is only slightly better than the 4K Ultra result (89 FPS) suggests that the game becomes increasingly dependent on the CPU's physics calculations as resolution increases, rather than purely on GPU rasterization.

Settings Recommendations

The measured data provides a clear hierarchy for optimal settings, with the Medium preset offering the best balance between visual fidelity and frame rate stability. At 1920x1080, the Medium preset delivers an average of 235 FPS with a minimum of 200 FPS and a maximum of 270 FPS. This is the only settings level at 1080p where min/max data was captured, indicating more consistent frame pacing. In contrast, the High and Ultra presets both hover around 203-206 FPS on average, with no recorded minimums, suggesting potential variance. The Low preset at 1080p reaches 267 FPS, but this comes at the cost of visual quality that is likely too severe for a game that relies on visual feedback for system building.

For 2560x1440, the Medium preset again stands out as the recommended choice. It produces an average of 202 FPS, with a minimum of 171 FPS and a maximum of 232 FPS. The High preset at 1440p averages 177 FPS, while Ultra averages 171 FPS. The difference between Medium and Ultra at this resolution is only 31 FPS, but the Medium preset's recorded minimum of 171 FPS indicates that it can maintain playable frame rates even during demanding simulation sequences. The data shows that the Ultra preset at 1440p, while visually superior, does not offer a significant frame rate advantage over High, and both are noticeably below Medium.

At 3840x2160, the decision becomes more nuanced. The Medium preset provides an average of 133 FPS, with a minimum of 113 FPS and a maximum of 153 FPS. This is the only 4K setting with min/max data, and it shows a very playable experience. The High preset at 4K averages 94 FPS, and Ultra averages 89 FPS. While the Ultra preset at 4K is technically playable, the data suggests that the Medium preset at 4K is the superior choice for maintaining a high refresh rate experience. The 44 FPS gap between Medium (133 FPS) and Ultra (89 FPS) at 4K is substantial, and the Medium preset's minimum of 113 FPS ensures the frame rate rarely dips below the 100 FPS threshold.

GPU Role

The NVIDIA GeForce RTX 5090 D is a formidable graphics card, with its 32 GB of GDDR7 memory and 512-bit bus width providing a bandwidth of 1.79 TB/s. Its raw compute capabilities, including 21,760 shading units and a boost clock of 2407 MHz, are reflected in its Passmark G3D score of 44,065. However, in Pc Building Simulator, the GPU's role is often secondary to the CPU. The data shows that the GPU's massive memory pool is rarely taxed, as the game's asset sizes and texture requirements are not demanding enough to utilize 32 GB. The card's performance percentile of 92% versus all GPUs indicates it is among the top performers, yet the measured FPS in this game do not always reflect that top-tier status.

The GPU's clock speeds, base 2017 MHz and boost 2407 MHz, are consistent with a high-end Blackwell 2.0 architecture part. The 104.8 TFLOPS of FP32 performance is more than sufficient for any current game, but the benchmark results in Pc Building Simulator show that the card is often waiting on the CPU. The deltaPct values for the GPU's nearest rivals are telling: the AMD Radeon RX 6850M XT is 1.6% faster in average benchmark scores, and the NVIDIA Tesla P100 PCIe 16 GB is 2.4% faster. This indicates that the RTX 5090 D, while powerful, is not universally dominant in all synthetic tests, and its performance in a simulation game may not fully leverage its architectural advantages.

The GPU's 176 ROPs and 680 TMUs provide ample pixel and texture processing capabilities, which is why the 4K High preset can still achieve 94 FPS. However, the frame rate data suggests that the GPU's role becomes more pronounced at higher resolutions. The transition from 1440p High (177 FPS) to 4K High (94 FPS) represents a 47% drop, which is a more significant reduction than the 14% drop seen from 1080p to 1440p. This indicates that the RTX 5090 D is only fully engaged at 4K resolution, where its 1.79 TB/s memory bandwidth and 423.6 GPixel/s pixel rate are needed to maintain playable frame rates. At lower resolutions, the GPU is effectively underutilized, with the CPU acting as the primary bottleneck.

How This Combo Ranks

The AMD Ryzen 7 3700X and NVIDIA GeForce RTX 5090 D combination ranks 366 out of 3,002 tested combos in Pc Building Simulator, placing it in the top 12.2% of all configurations. This ranking is somewhat surprising given the GPU's high performance percentile of 92% and the CPU's 84th percentile among all CPUs. The data indicates that the combination underperforms relative to what the individual component benchmarks would suggest, likely due to the CPU's age and the game's dependence on single-threaded performance. The Ryzen 7 3700X, with its 3.60 GHz base clock and 4.40 GHz boost clock, is a Zen 2 architecture part that was released in 2019, and its Passmark single-thread score of 2656 is modest by modern standards.

The ranking of 366 out of 3,002 combos means that approximately 2,636 other combinations achieve higher frame rates in this game. This is a significant finding, as it suggests that pairing a top-tier GPU like the RTX 5090 D with a mid-range CPU from the previous generation creates a substantial bottleneck. The combo's rank is likely dragged down by the CPU's performance in the game's physics and simulation calculations, which are more dependent on integer and single-threaded workloads. The CPU's Passmark integer math score of 66,399 and find prime numbers score of 99 are relevant here, as these are the types of operations that Pc Building Simulator's logic would rely on.

The 3,002 total combos in the database provide a wide comparison field, and the 366th rank indicates that while this is not a poor combination, it is far from optimal. The data suggests that a newer CPU with higher single-threaded performance, even if paired with a less powerful GPU, could achieve a better ranking in this specific game. The combo's position in the top 12.2% is respectable, but it falls short of what the RTX 5090 D's capabilities would imply. This is a classic example of a GPU-limited system being held back by CPU limitations, and the rank reflects that the full potential of the graphics card is not being realized.

FAQ

Q: What is the best resolution for this combo to maintain a high refresh rate?

A: The data shows that at 2560x1440 with Medium settings, the combo achieves an average of 202 FPS with a minimum of 171 FPS. This is the highest resolution where the average FPS exceeds 200, making it the optimal choice for high refresh rate monitors. At 3840x2160, the Medium preset drops to 133 FPS average, which is still playable but below the 144Hz threshold.

Q: How does the CPU's single-threaded performance affect the frame rates?

A: The Ryzen 7 3700X has a Geekbench single-core score of 1593 and a Passmark single-thread score of 2656. The data indicates that at 1080p and 1440p, the frame rate scaling is nearly identical between Low and High settings, which suggests the CPU's single-threaded performance is the limiting factor. The 14% drop from 1080p to 1440p Low (267 to 229 FPS) mirrors the 14% drop at High settings (206 to 177 FPS), confirming CPU limitation.

Q: Is the RTX 5090 D's 32 GB of VRAM necessary for this game?

A: The benchmark results do not provide specific VRAM usage data, but the game's performance at 4K Ultra (89 FPS) and 4K High (94 FPS) shows no indication that memory capacity is a bottleneck. The GPU's 32 GB of GDDR7 memory is more than sufficient for Pc Building Simulator, which is a simulation game with relatively modest texture requirements compared to AAA action titles.

Q: Why does the combo rank only 366th out of 3,002 combos despite the powerful GPU?

A: The ranking is likely due to the CPU's performance in the game's simulation logic. The Ryzen 7 3700X's 8 cores and 16 threads provide adequate multi-threaded performance, but the game appears to be sensitive to single-threaded speed. The CPU's percentile rank of 84% versus all CPUs is lower than the GPU's 92% percentile, creating an imbalance that holds back the overall combo performance.

Q: What is the frame rate difference between the Medium and Ultra presets at 1080p?

A: At 1920x1080, the Medium preset averages 235 FPS, while the Ultra preset averages 203 FPS. This is a 32 FPS difference (approximately 14%). The Medium preset also has a recorded minimum of 200 FPS and maximum of 270 FPS, while the Ultra preset has no recorded min/max values, suggesting more consistent performance at Medium.

Q: Does the game scale well with the GPU's memory bandwidth?

A: The RTX 5090 D has a memory bandwidth of 1.79 TB/s, which is exceptionally high. The data shows that from 1440p High (177 FPS) to 4K High (94 FPS), the frame rate drops by 47%, which is a significant penalty. This suggests that the game does not heavily leverage the GPU's bandwidth, as the drop is more consistent with a CPU bottleneck than a memory bandwidth limitation.

Measured FPS Breakdown

At 1920x1080, the measured average FPS values are 267 for Low, 235 for Medium, 206 for High, and 203 for Ultra. The Medium preset at this resolution has a minimum of 200 FPS and a maximum of 270 FPS, providing the only complete min/max data at 1080p. The difference between Low and Medium is 32 FPS, while the difference between High and Ultra is only 3 FPS, indicating that the Ultra preset offers minimal performance benefit over High at 1080p.

Moving to 2560x1440, the average FPS values are 229 for Low, 202 for Medium, 177 for High, and 171 for Ultra. The Medium preset at 1440p has a minimum of 171 FPS and a maximum of 232 FPS. The drop from 1080p to 1440p is consistent across all settings: Low drops by 38 FPS, Medium by 33 FPS, High by 29 FPS, and Ultra by 32 FPS. This consistency reinforces the CPU bottleneck theory, as the GPU's workload increase does not disproportionately affect any particular preset.

At 3840x2160, the average FPS values are 185 for Low, 133 for Medium, 94 for High, and 89 for Ultra. The Medium preset at 4K has a minimum of 113 FPS and a maximum of 153 FPS. The scaling from 1440p to 4K is more dramatic: Low drops by 44 FPS, Medium by 69 FPS, High by 83 FPS, and Ultra by 82 FPS. This indicates that at 4K, the GPU becomes the limiting factor, and the RTX 5090 D's performance scales more predictably with settings changes. The 4K Low preset at 185 FPS is notably higher than the 4K High preset at 94 FPS, a 91 FPS difference, showing that the GPU has significant headroom when settings are lowered.

CPU Role

The AMD Ryzen 7 3700X is a 7 nm Zen 2 architecture processor with 8 cores and 16 threads, codenamed Matisse. Its base clock of 3.60 GHz and boost clock of 4.40 GHz, combined with a 32 MB L3 cache, provide a solid foundation for gaming. However, the benchmark data from Pc Building Simulator reveals that the CPU's role is primarily as a bottleneck at resolutions below 4K. The CPU's Passmark multithread score of 22,458 and Cinebench R15 multicore score of 2092 indicate strong multi-threaded capabilities, but the game's simulation logic appears to rely more heavily on single-threaded performance, where the CPU's Cinebench R15 single-core score of 204 is less impressive.

The CPU's memory support for DDR4 with dual-channel configuration and 51.2 GB/s bandwidth is adequate for the game, but it may contribute to the bottleneck at high frame rates. The data shows that at 1080p Low, the system reaches 267 FPS, which is likely near the maximum frame rate that the CPU can generate. The fact that increasing the resolution to 1440p only reduces the frame rate by 38 FPS (14%) suggests that the CPU is already operating near its limit at 1080p. The CPU's 65 W TDP and 24 PCIe Gen 4 lanes provide efficient power delivery and data transfer, but these attributes do not compensate for the architectural limitations in single-threaded workloads.

The CPU's nearest rivals in benchmark scores include the AMD Ryzen AI 7 350 (0.1% faster) and Intel Core i5-13450HX (0.2% slower), which are both newer architectures. This comparison highlights that the Ryzen 7 3700X, while still competitive in synthetic benchmarks, is aging in terms of per-core performance. In Pc Building Simulator, this translates to a ceiling on frame rates that the RTX 5090 D cannot overcome. The CPU's 16 threads do help maintain smooth frame pacing in the game's more complex simulation scenarios, as evidenced by the Medium preset's recorded minimum FPS values, but the overall performance is constrained by the Zen 2 core design's instruction throughput.
