Pc Building Simulator

Pc Building Simulator is a simulation title that thrives on CPU and memory subsystem performance, and the pairing of the Intel Core Ultra 5 235 with the NVIDIA GeForce RTX 5090 produces a fascinating dataset that reveals the game's unique scaling behavior. The measured frame rates across three resolutions and four quality presets show a configuration that is rarely the limiting factor, with the RTX 5090's immense power being held back by the simulation's engine and the CPU's 14-core, 14-thread layout. The data indicates that this combo is capable of extreme frame rates at lower resolutions, but the demands of 4K Ultra finally begin to stress the GPU, providing a clear picture of where each component's headroom lies.

Resolution Scaling

The frame rate progression from 1080p to 4K reveals that Pc Building Simulator is heavily CPU-bound at lower resolutions, with the GPU only becoming a significant constraint at the highest settings and resolution. At Low settings, the RTX 5090 is effectively unchained, producing 454 FPS at 1920x1080, 336 FPS at 2560x1440, and 176 FPS at 3840x2160. This represents a 61% drop from 1080p to 4K, which is a substantial scaling penalty but still leaves the system operating at refresh rates far beyond what most displays can showcase. The fact that the 4K Low result is still nearly double the 1080p High result of 266 FPS suggests that even at 4K, the CPU is the primary bottleneck at lower quality presets, as the GPU has ample headroom to spare.

Moving to Medium settings, the scaling becomes more linear and GPU-dependent. At 1080p Medium, the system achieves 377 FPS, which drops to 238 FPS at 1440p and 124 FPS at 4K. The 4K Medium result of 124 FPS is a 67% reduction from the 1080p Medium figure, indicating that the increased shader complexity and memory pressure are starting to engage the RTX 5090's 32 GB of GDDR7 memory and 104.8 TFLOPS of compute power. The 1440p Medium result of 238 FPS shows a 37% drop from 1080p, which is a more modest scaling penalty than the 4K step, reinforcing that the GPU's 512-bit memory bus and 1.79 TB/s bandwidth are well-suited to handle the intermediate resolution without major concessions.

At High settings, the scaling pattern continues, with 266 FPS at 1080p, 168 FPS at 1440p, and 88 FPS at 4K. The 4K High result is a 67% reduction from 1080p High, matching the Medium preset's scaling penalty almost exactly. This consistency suggests that the game's rendering engine scales predictably with resolution, and the RTX 5090's 32 GB VRAM is not being exhausted at any of these settings, as the minimum frame rates recorded at Medium settings (106 FPS at 4K) indicate stable performance without memory-related stuttering. The Ultra preset tells a similar story: 253 FPS at 1080p, 160 FPS at 1440p, and 84 FPS at 4K, with the 4K Ultra result representing a 67% drop from 1080p Ultra, again mirroring the other presets' scaling behavior.

The most telling observation is that the gap between 1080p and 1440p is consistently around 37-40% across all settings, while the gap between 1440p and 4K is consistently around 48-50%. This non-linear scaling indicates that the game's simulation logic, which is CPU-intensive, becomes less of a factor as resolution increases, allowing the GPU to take over. At 4K Ultra, the 84 FPS result is the only measured point where the RTX 5090 appears to be the clear limiting component, as the combination of maximum geometry, textures, and post-processing effects finally saturates the GPU's capabilities. The data strongly suggests that for competitive or high-refresh-rate play, 1080p and 1440p are entirely CPU-bound, while 4K is the only resolution where the GPU's 575 W TDP and 92,200 million transistors are truly put to work.

Settings Recommendations

The measured data provides a clear hierarchy for optimizing the experience with this specific CPU and GPU combination. For players targeting 4K, the Medium preset at 124 FPS offers the best balance of visual fidelity and performance, as the jump to High drops the average to 88 FPS, a 29% reduction that may be noticeable on high-refresh-rate 4K panels. The Ultra preset at 84 FPS is only marginally slower than High, suggesting that the extra visual features in Ultra are relatively inexpensive on the RTX 5090, but the 4K Medium result of 124 FPS remains the sweet spot for maintaining a smooth experience above the 100 FPS threshold. The minimum frame rate of 106 FPS recorded at 4K Medium confirms that even the worst-case frame times stay comfortably within playable territory.

At 1440p, the High preset at 168 FPS is the recommended choice, as it provides a significant visual upgrade over Medium's 238 FPS without the 144 FPS difference being perceptible to most users. The 1440p Ultra result of 160 FPS is only 5% slower than High, making Ultra a viable option for those with 144Hz or 165Hz monitors who want maximum visual quality. The 1440p Low preset at 336 FPS is unnecessary for any practical display, as it exceeds the refresh rate of even the most advanced gaming monitors, and the visual compromises are not worth the extra frames. The Medium preset at 1440p, with its minimum frame rate of 202 FPS, is the safest choice for competitive play where frame pacing consistency is paramount.

For 1080p, the Ultra preset at 253 FPS is the obvious recommendation, as it delivers the highest visual quality while still maintaining frame rates that exceed the refresh rate of virtually all gaming displays. The 1080p High preset at 266 FPS is nearly identical in performance, making the choice between High and Ultra purely a matter of visual preference rather than performance. The 1080p Medium preset at 377 FPS and Low preset at 454 FPS are only useful for esports-style play on 360Hz or 500Hz monitors, which are the only display types that could benefit from such extreme frame rates. Given that the game is a simulation about building PCs, the Ultra preset at 1080p provides the most immersive experience without sacrificing any measurable performance, and the 84 FPS minimum at 4K Ultra suggests that even the most demanding settings are playable on this hardware.

FAQ

Q: Is the RTX 5090 overkill for Pc Building Simulator at 1080p?

A: The data shows the RTX 5090 produces 454 FPS at 1080p Low and 253 FPS at 1080p Ultra, indicating the GPU is heavily underutilized at this resolution. The CPU's 14-core, 14-thread configuration and the game's simulation engine are the limiting factors, as the GPU's 32 GB VRAM and 104.8 TFLOPS compute remain largely idle.

Q: What is the best resolution for this combo to maintain above 144 FPS?

A: At 1440p High, the system achieves 168 FPS, and at 1440p Ultra it reaches 160 FPS, both above the 144 FPS threshold. At 4K, only the Medium preset at 124 FPS falls short of 144 FPS, making 1440p the highest resolution that consistently maintains triple-digit refresh rates across all presets.

Q: How does the 4K Ultra performance compare to 4K Medium?

A: The 4K Ultra preset delivers 84 FPS, while the 4K Medium preset achieves 124 FPS, representing a 32% performance penalty for the highest quality settings. The 4K Medium result also has a recorded minimum frame rate of 106 FPS, whereas the Ultra preset has no recorded minimum, suggesting the Medium preset offers more consistent frame pacing.

Q: Does the RTX 5090's 32 GB VRAM ever become a bottleneck in this game?

A: The measured frame rates do not indicate any VRAM-related performance drops, as the minimum frame rates at Medium settings (106 FPS at 4K, 202 FPS at 1440p, 320 FPS at 1080p) show stable performance. The GPU's 1.79 TB/s memory bandwidth and 512-bit bus appear sufficient for all tested settings.

Q: Is the Core Ultra 5 235 the limiting component at 1080p?

A: Yes, the scaling data confirms this. From 1080p High to 4K High, the frame rate drops from 266 FPS to 88 FPS, but the fact that 1080p Low reaches 454 FPS while 4K Low only reaches 176 FPS indicates the CPU cannot feed the GPU fast enough at lower resolutions, with the 14 threads being the primary constraint.

Q: What frame rate can be expected at 1440p Medium with this combo?

A: The measured average is 238 FPS, with a minimum of 202 FPS and a maximum of 274 FPS. This represents a 29% improvement over the 1440p High preset's 168 FPS, making Medium the best choice for those prioritizing frame rate over visual detail at this resolution.

How This Combo Ranks

The Intel Core Ultra 5 235 and NVIDIA GeForce RTX 5090 combination ranks 45th out of 3,002 tested combos in Pc Building Simulator, placing it in the top 1.5% of all configurations. This ranking is notably strong, but the data suggests that the RTX 5090's raw power is not the primary driver of this high placement. The CPU's 89th percentile ranking among all processors, with an average benchmark score of 46,062, puts it in the upper echelon of desktop CPUs, but its nearest rivals reveal a tight cluster: the AMD Ryzen AI 9 HX 375 scores 46,030 (0.1% faster), the Intel Core i9-13900HX scores 46,098 (0.1% slower), and the AMD EPYC 4364P scores 45,970 (0.2% faster). This indicates that the Core Ultra 5 235 is competitively positioned but not exceptional among its peers.

The GPU, however, tells a different story. The RTX 5090 ranks in the 92nd percentile among all GPUs with an average benchmark score of 79,842, and its nearest rivals are professional and mobile parts: the NVIDIA Tesla P100 PCIe 16 GB scores 79,605 (0.3% faster), the Tesla P100 PCIe 12 GB scores 79,396 (0.6% faster), and the AMD Radeon RX 6850M XT scores 78,940 (1.1% faster). These deltas are all within 1.5%, meaning the RTX 5090 is at the very top of the consumer GPU hierarchy, but its 92nd percentile ranking among all GPUs suggests that there are workstation and server parts that outperform it in synthetic benchmarks.

The combo's 45th place ranking out of 3,002 is likely influenced by the fact that Pc Building Simulator is a CPU-intensive simulation title, and the Core Ultra 5 235's 14 cores and 14 threads (with no hyperthreading) may not be optimally suited for this workload. The measured frame rates at 4K Ultra (84 FPS) are respectable but not class-leading, and the ranking would likely be higher with a CPU that has more threads, such as the Ryzen AI 9 HX 375 or Core i9-13900HX, which are within 0.1% of the Core Ultra 5 235's average score. The data indicates that this combo is well-balanced for general gaming, but in a simulation title that rewards strong single-thread and multi-thread performance, the Core Ultra 5 235's 3.40 GHz base clock and 5.00 GHz boost clock are sufficient to place it in the top 50, though not the top 10.

GPU Role

The NVIDIA GeForce RTX 5090 is the dominant component in this pairing, and its specifications explain the measured performance ceiling at 4K. With 32 GB of GDDR7 memory on a 512-bit bus, the GPU offers 1.79 TB/s of bandwidth, which is critical for a simulation game that may load large texture sets and complex 3D models. The 21760 shading units, 680 TMUs, and 176 ROPs provide 104.8 TFLOPS of FP32 compute, and the 170 RT cores and 680 tensor cores handle ray tracing and AI acceleration, though Pc Building Simulator likely does not heavily utilize these features. The 2017 MHz base clock and 2407 MHz boost clock are the highest in the GeForce 50-series, and the 575 W TDP requires a 950 W suggested PSU, making this a power-hungry but capable part.

The GPU's role in the measured results becomes clear when examining the resolution scaling. At 1080p, the RTX 5090 is never the bottleneck, as even the Ultra preset at 253 FPS leaves the GPU with significant headroom. The 32 GB VRAM is never fully utilized, as the game's maximum memory footprint at 4K Ultra does not appear to exceed the 32 GB allocation, based on the absence of frame drops. The 1.79 TB/s bandwidth is also more than sufficient, as the minimum frame rates at Medium settings (106 FPS at 4K) show no signs of memory bandwidth throttling. The GPU's 92nd percentile ranking among all GPUs, with an average benchmark score of 79,842, confirms that it is one of the fastest consumer cards available, but its performance in this game is constrained by the CPU.

At 4K Ultra, the RTX 5090 finally becomes the limiting factor, with the 84 FPS result representing the GPU's maximum capability under the game's heaviest load. The pixel rate of 423.6 GPixel/s and texture rate of 1,636.8 GTexel/s are theoretical maxima that the game's engine cannot fully exploit, but the 4K Ultra result of 84 FPS indicates that the GPU is working near its practical limits. The GPU's 5 nm process node and 92,200 million transistors on a 750 mm² die are the largest consumer chip ever made, and this hardware advantage is what allows the combo to maintain playable frame rates at 4K Ultra, even if the 84 FPS result is below the 100 FPS threshold that many gamers prefer. The GPU's role is therefore to provide a high ceiling for resolution and settings scaling, while the CPU determines the floor at lower resolutions.

Measured FPS Breakdown

At 1920x1080, the measured frame rates show a clear hierarchy across settings. The Low preset achieves 454 FPS, which is the highest recorded result in the entire dataset, followed by Medium at 377 FPS with a minimum of 320 FPS and a maximum of 433 FPS. The High preset drops to 266 FPS, and Ultra is close behind at 253 FPS. The gap between Low and Medium is 77 FPS (17%), while the gap between Medium and High is 111 FPS (29%), and the gap between High and Ultra is only 13 FPS (5%). This indicates that the game's visual settings have diminishing returns beyond High, with Ultra offering minimal performance impact at this resolution.

At 2560x1440, the frame rates scale downward proportionally. Low produces 336 FPS, Medium achieves 238 FPS with a minimum of 202 FPS and a maximum of 274 FPS, High reaches 168 FPS, and Ultra delivers 160 FPS. The 1440p results are consistently 26-37% lower than their 1080p counterparts across all settings, with the Low preset showing the largest drop (26%) and the High preset showing the largest drop (37%). The Medium preset's minimum of 202 FPS is notable, as it remains above the 200 FPS threshold, suggesting that the GPU and CPU combination can maintain high frame rates even during demanding simulation moments.

At 3840x2160, the frame rates reach their lowest points. Low produces 176 FPS, Medium achieves 124 FPS with a minimum of 106 FPS and a maximum of 143 FPS, High drops to 88 FPS, and Ultra is the lowest at 84 FPS. The 4K results are 48-61% lower than their 1080p counterparts, with the Low preset showing the smallest drop (61%) and the Ultra preset showing the largest drop (67%). The 4K Medium result of 124 FPS is the only 4K setting above the 100 FPS threshold, and its minimum of 106 FPS indicates that frame pacing remains stable even under load. The 4K Ultra result of 84 FPS is the only measured point where the RTX 5090 is clearly the limiting component, as the GPU's 104.8 TFLOPS of compute is fully saturated by the game's maximum settings.
