Pc Building Simulator

Pc Building Simulator presents an interesting case for the AMD Ryzen 5 5600X and NVIDIA GeForce RTX 4080 combination. The data shows a system that is overwhelmingly capable at standard resolutions, but the performance curve reveals a shift in bottleneck behavior as resolution increases. This analysis walks through the measured FPS data to interpret what it means for this specific pairing.

Resolution Scaling

The measured FPS data shows a clear and predictable pattern: performance degrades as resolution increases, but the rate of that degradation is not uniform across settings. At Low settings, the system pushes 339 FPS at 1920x1080, which drops to 291 FPS at 2560x1440 (a 14.2% decrease), and then falls to 155 FPS at 3840x2160 (a 46.7% decrease from 1440p). This steep drop from 1440p to 4K at Low settings indicates that the GPU is becoming the limiting factor, as the pixel count quadruples while the frame rate does not come close to halving.

At Medium settings, the scaling is smoother: 298 FPS at 1080p, 210 FPS at 1440p (a 29.5% drop), and 110 FPS at 4K (a 47.6% drop from 1440p). The High preset shows a similar proportional decline: 235 FPS at 1080p, 148 FPS at 1440p (a 37% drop), and 78 FPS at 4K (a 47.3% drop from 1440p). The Ultra preset follows suit with 224 FPS at 1080p, 141 FPS at 1440p (a 37.1% drop), and 74 FPS at 4K (a 47.5% drop from 1440p).

The consistency of the percentage drop from 1440p to 4K across all settings — hovering around 47% — strongly suggests that the GPU is the primary bottleneck at 4K. The RTX 4080's 16 GB of GDDR6X memory and 716.8 GB/s bandwidth are being saturated by the higher resolution, regardless of the graphical preset. Conversely, the gap between 1080p and 1440p is smaller at Low settings (14.2% drop) than at High or Ultra (37% drop), implying that at 1080p the CPU has more headroom to maintain high frame rates even as GPU load increases.

Benchmark results indicate that at 1080p, the system is likely CPU-bound in this simulation title. The Ryzen 5 5600X, with its 6 cores and 12 threads, manages to feed the RTX 4080 enough data to achieve over 300 FPS at Low and Medium settings. However, the Ultra preset at 1080p (224 FPS) is only slightly lower than High (235 FPS), suggesting that the CPU's limits are being approached. The data shows that 4K is where the RTX 4080's raw power is fully utilized, with the frame rate dropping to a range (74-155 FPS depending on settings) that is more typical of a GPU-limited scenario.

CPU Role

The AMD Ryzen 5 5600X is a 6-core, 12-thread processor based on the Zen 3 architecture, codenamed Vermeer. It operates at a base clock of 3.70 GHz and a boost clock of 4.60 GHz, with a 65 W TDP. In synthetic benchmarks, it scores 917 in 3dmark single-thread, 5588 in 3dmark max-threads, and 11838 in Cinebench R23 multicore. Its average benchmark score is 21771, placing it in the 75th percentile of all CPUs.

When comparing to its nearest rivals, the Ryzen 5 5600X is essentially tied with the AMD Ryzen 7 4800H (0.1% difference) and is 0.5% behind both the AMD Ryzen 5 PRO 6650U and the Intel Core i7-11700. It is 0.6% ahead of the AMD EPYC 9554P. These negligible differences mean that in Pc Building Simulator, any of these CPUs would produce nearly identical CPU-bound frame rates.

The CPU's role in this game becomes clear when examining the FPS at 1080p. At Low settings, the system achieves 339 FPS, which is exceptionally high. However, the fact that increasing settings to Ultra only drops the frame rate to 224 FPS (a 33.9% reduction) suggests that the CPU is not being fully taxed at these frame rates. The 12 threads of the 5600X are likely sufficient for the simulation logic, which typically benefits from single-thread performance more than raw multicore throughput. The 3dmark single-thread score of 917 and Cinebench R23 single-core score of 1541 indicate solid per-core performance that can handle the game's physics and AI calculations.

At 1440p, the CPU still has enough headroom to keep frame rates above 140 FPS even at Ultra settings. The data shows that the drop from 1080p to 1440p is more pronounced at higher settings (37% for High and Ultra) compared to Low (14.2%), which means the CPU is still the main driver at 1080p but starts to yield to the GPU as resolution increases. At 4K, the CPU role diminishes significantly, as the GPU becomes the clear bottleneck regardless of settings.

GPU Role

The NVIDIA GeForce RTX 4080 is based on the Ada Lovelace architecture with the AD103 chip, manufactured on a 5 nm process. It features 9728 shading units, 304 TMUs, and 112 ROPs, with a base clock of 2205 MHz and a boost clock of 2505 MHz. The 16 GB of GDDR6X memory runs at 1400 MHz (22.4 Gbps effective) across a 256-bit bus, delivering 716.8 GB/s of bandwidth. Its average benchmark score is 54247, placing it in the 86th percentile of all GPUs.

The RTX 4080's nearest rivals are the NVIDIA GeForce RTX 4080 SUPER (0.1% ahead), the AMD Radeon Pro W5700X (1.1% behind), the AMD Radeon RX 6750 GRE 12 GB (2.6% behind), and the AMD Radeon 8060S (2.7% behind). These small deltas mean that the RTX 4080 is positioned at the top tier of GPUs, and its performance in Pc Building Simulator reflects this.

The GPU's role is most evident at 4K resolution. At 3840x2160, the RTX 4080 delivers 155 FPS at Low settings, 110 FPS at Medium, 78 FPS at High, and 74 FPS at Ultra. The relatively small gap between High (78 FPS) and Ultra (74 FPS) — just 5.1% — indicates that the GPU is being pushed to its limits, and additional graphical fidelity comes at a high cost. The 16 GB VRAM is likely sufficient for the game's textures at 4K, but the sheer pixel throughput demands the full bandwidth of 716.8 GB/s.

At 1440p, the RTX 4080 shows more headroom: 291 FPS at Low, 210 FPS at Medium, 148 FPS at High, and 141 FPS at Ultra. The gap between High and Ultra shrinks to 4.7%, suggesting that the GPU is still working hard but has enough bandwidth to maintain playable frame rates. At 1080p, the GPU is almost never the limiting factor, as even Ultra settings produce 224 FPS. The data shows that the RTX 4080's 48.74 TFLOPS of FP32 performance is ample for this simulation game at all but the most demanding 4K Ultra scenarios.

How This Combo Ranks

In Pc Building Simulator, this combination of AMD Ryzen 5 5600X and NVIDIA GeForce RTX 4080 ranks 336th out of 3723 tested combos. This places it in the top 9% of all combinations in the database, which is a strong showing for a CPU that is not the newest generation and a GPU that is now marked as end-of-life.

The ranking reflects the balance between the two components. The CPU's 75th percentile ranking among all CPUs and the GPU's 86th percentile ranking among all GPUs combine to produce a system that is above average but not at the absolute top. The 3723 combos include many with newer, higher-end CPUs like the Ryzen 7000 series or Intel 13th/14th gen, which would push this combo down in the rankings despite the RTX 4080's strong performance.

However, the gap to the top is not enormous. The data shows that the RTX 4080 is within 0.1% of the RTX 4080 SUPER, meaning the GPU is not the limiting factor in the ranking. Instead, the Ryzen 5 5600X's 6 cores, while sufficient for this game, hold back the overall combo ranking when compared to CPUs with more cores or higher single-thread performance. The 3dmark 16-thread score of 5582 and the passmark multithread score of 21858 are respectable but not class-leading.

For Pc Building Simulator specifically, the ranking is likely higher than the overall average because the game is not heavily multithreaded. The simulation genre tends to favor single-thread performance, where the 5600X's 917 3dmark single-thread score and 1541 Cinebench R23 single-core score are competitive. This means the combo's 336th rank may underrepresent its actual in-game performance, which is excellent as shown by the FPS data.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and desired frame rate. At 1920x1080, all settings produce playable frame rates, but the difference between Medium (298 FPS) and Ultra (224 FPS) is 74 FPS. For a 144 Hz or 165 Hz monitor, Medium settings at 1080p provide a significant FPS buffer, while High (235 FPS) offers a better visual experience with still ample headroom.

At 2560x1440, the choice is more nuanced. Medium settings deliver 210 FPS with a minimum of 179 FPS, which is ideal for high-refresh-rate gaming. High settings drop to 148 FPS, which is still above 144 Hz, and Ultra falls to 141 FPS, just below the 144 Hz threshold. For a 1440p 144 Hz display, High settings are the best balance, providing 148 FPS average with no listed minimum FPS issues. If a 165 Hz monitor is used, Medium is safer due to its 179 FPS minimum.

At 3840x2160, the data suggests that High settings (78 FPS) are the sweet spot for a 60 Hz or 75 Hz display. Ultra (74 FPS) offers only a 5.1% visual improvement at a 5.1% FPS cost, making it a marginal upgrade. Low settings (155 FPS) are overkill for most 4K displays, which typically cap at 120 Hz or 144 Hz. Medium (110 FPS) is a good choice for 4K 120 Hz displays, providing a comfortable margin above the refresh rate.

The minimum FPS data at Medium settings is instructive: 253 FPS at 1080p, 179 FPS at 1440p, and 93 FPS at 4K. These minimums indicate that the system maintains stable frame times, with no severe dips. For the smoothest experience across all resolutions, Medium settings are recommended, as they offer the best combination of high average FPS and consistent minimum FPS.

Measured FPS Breakdown

The complete measured FPS data for this combo is as follows:

1920x1080:

• Low: 339 FPS average
• Medium: 298 FPS average, 253 FPS minimum, 343 FPS maximum
• High: 235 FPS average
• Ultra: 224 FPS average

2560x1440:

• Low: 291 FPS average
• Medium: 210 FPS average, 179 FPS minimum, 242 FPS maximum
• High: 148 FPS average
• Ultra: 141 FPS average

3840x2160:

• Low: 155 FPS average
• Medium: 110 FPS average, 93 FPS minimum, 126 FPS maximum
• High: 78 FPS average
• Ultra: 74 FPS average

The data reveals several key patterns. First, the jump from Low to Medium at each resolution incurs a significant FPS penalty: 41 FPS at 1080p, 81 FPS at 1440p, and 45 FPS at 4K. This suggests that Medium settings introduce additional GPU workload that is not proportional to the visual improvement. Second, the gap between High and Ultra is consistently narrow: 11 FPS at 1080p, 7 FPS at 1440p, and 4 FPS at 4K. This indicates that Ultra settings are not well-optimized or that the GPU is already near its limits at High.

The maximum FPS at Medium settings (343 at 1080p, 242 at 1440p, 126 at 4K) shows that the system can briefly exceed the average by a wide margin, suggesting that frame pacing is generally smooth but can spike in less demanding scenes. The minimum FPS at Medium (253 at 1080p, 179 at 1440p, 93 at 4K) confirms that the system rarely dips below playable thresholds, even at 4K.

Overall, the measured data paints a picture of a highly capable system that excels at 1440p and below, with 4K performance that is still very playable at High settings. The Ryzen 5 5600X and RTX 4080 combination is well-matched for this simulation title, with the CPU handling lower resolutions effortlessly and the GPU taking over as the primary driver at 4K.
