# Pc Building Simulator with Intel Core Ultra 7 155H + NVIDIA GeForce RTX 5090

This combination of Intel's 16-core mobile processor and NVIDIA's flagship 32 GB graphics card delivers a fascinating split personality in Pc Building Simulator: at 1080p the frame rates soar past 300 FPS, while at 4K Ultra the experience drops to just 61 FPS average. The measured data reveals a simulation game that is far more demanding on the GPU at higher resolutions than its modest visual complexity might suggest, with the RTX 5090's 32 GB VRAM and 1.79 TB/s bandwidth proving essential for maintaining playable frame rates at 4K.

Settings Recommendations

The measured FPS rows provide a clear hierarchy of playable presets across all three resolutions. At 1080p, even the Ultra preset delivers 184 FPS average, which is far beyond what any display can typically show, while Low pushes to 345 FPS. The Medium preset at 1080p shows a 274 FPS average with a minimum of 233 FPS, suggesting that even the most demanding in-game scenes remain comfortably fluid. For competitive or high-refresh-rate monitors, Low at 1080p is the clear choice, but the data indicates that players can select any preset at 1080p without worrying about performance drops below playable thresholds.

At 1440p, the picture becomes more nuanced. Ultra still manages 116 FPS average, while High sits at 122 FPS, and Medium reaches 173 FPS with a minimum of 147 FPS. Low jumps to 244 FPS. The gap between Medium and High is only 51 FPS, but the minimum frame rate data for Medium (147 FPS) suggests that Medium provides the best combination of smoothness and visual fidelity for 1440p gaming. The Ultra preset at 1440p, while averaging 116 FPS, lacks min/max data, so the Medium preset's documented floor of 147 FPS makes it the safer recommendation for consistent performance.

At 4K, the choices become more critical. Ultra falls to 61 FPS average, which is right at the edge of what many consider playable for a simulation game, while High manages 64 FPS. Medium delivers 90 FPS average with a minimum of 77 FPS and a maximum of 104 FPS, making it the only 4K preset with documented frame time stability. Low reaches 127 FPS. Given the data, Medium at 4K is the optimal balance: it provides a 47% improvement over High in average FPS (90 vs 64) while maintaining a documented minimum above 75 FPS. The Ultra preset's 61 FPS average is likely to produce noticeable stutter in busy scenes, whereas Medium's 77 FPS floor suggests a much smoother experience.

CPU Role

The Intel Core Ultra 7 155H brings 16 cores and 22 threads from the Meteor Lake architecture, with a base clock of 3.80 GHz and a boost clock of 4.80 GHz. In Pc Building Simulator, the data suggests that the CPU is rarely the limiting factor at lower resolutions, but its influence becomes apparent when examining the 1080p results. At 1080p Low, the combination produces 345 FPS, which is remarkably high for a simulation game that must track numerous system components and their interactions. The 24 MB of shared L3 cache and dual-channel DDR5 memory support (89.6 GB/s bandwidth) likely help maintain this performance in CPU-bound scenarios.

The processor's benchmark results paint a picture of a capable mid-range mobile chip. Its Cinebench R23 multi-core score of 15028 places it in the 83rd percentile among all CPUs, with an average benchmark score of 32697. Compared to its nearest rivals, the Core Ultra 7 155H essentially trades blows with the Intel Core i5-14600T (deltaPct 0%) and the AMD Ryzen AI 7 PRO 360 (deltaPct 0.1%), while slightly trailing the AMD Ryzen 5 7400F (deltaPct -0.2%) and AMD Ryzen 7 PRO 6850H (deltaPct -0.4%). These near-zero deltas suggest that in synthetic benchmarks, the CPU is competitive with its peers, but in Pc Building Simulator, the actual game performance will depend on how well the title utilizes multiple cores.

The PassMark multi-thread score of 24873 and the integer math score of 86870 indicate strong sustained multi-core throughput, which is relevant for a game that simulates component interactions. However, the single-thread performance (PassMark single thread score of 3468) is more modest, and since many simulation games rely on a primary game thread, this could explain why the 1080p Low result of 345 FPS, while excellent, does not reach the extremes seen in some esports titles. The data implies that Pc Building Simulator at 1080p is at least partially CPU-bound, since the RTX 5090 is capable of far higher frame rates in GPU-bound scenarios, yet the measured 345 FPS ceiling at Low settings suggests the CPU's single-thread performance is the limiter.

GPU Role

The NVIDIA GeForce RTX 5090 is an absolute monster on paper: 32 GB of GDDR7 memory on a 512-bit bus delivering 1.79 TB/s bandwidth, with a boost clock of 2407 MHz and 104.8 TFLOPS of FP32 compute. The GPU's PassMark G3D score of 39650 places it in the 92nd percentile among all GPUs, with an average benchmark score of 79842. Its nearest rivals according to the data are surprisingly older professional cards: the NVIDIA Tesla P100 PCIe 16 GB (deltaPct 0.3%) and Tesla P100 PCIe 12 GB (deltaPct 0.6%), with the AMD Radeon RX 6850M XT slightly behind (deltaPct 1.1%) and the AMD Radeon Pro Vega 64X slightly ahead (deltaPct -1.4%). This suggests that the RTX 5090's raw compute power is comparable to these workstation-class GPUs, though its gaming-specific features like RT cores and tensor cores are not directly reflected in these comparison scores.

In Pc Building Simulator, the GPU's role becomes dominant as resolution increases. The frame rate scaling from 1080p to 4K is dramatic: at High settings, the average FPS drops from 193 at 1080p to 122 at 1440p (a 37% reduction), then to 64 at 4K (a 67% reduction from 1080p). This steep decline indicates that the game's rendering pipeline becomes heavily GPU-bound at higher resolutions, likely due to the need to render detailed system components, case interiors, and lighting effects simultaneously. The RTX 5090's 32 GB VRAM is particularly relevant here, as Pc Building Simulator's detailed 3D models of PC components can consume significant memory at 4K, and the data shows that the GPU maintains playable frame rates even at 4K Ultra (61 FPS).

The GPU's 170 RT cores and 680 tensor cores suggest that ray tracing and DLSS features could be available, but the measured data does not include any ray-traced or upscaled settings, so the analysis must focus on traditional rasterization performance. The 423.6 GPixel/s pixel rate and 1,636.8 GTexel/s texture rate indicate that the GPU has ample fill-rate headroom for high-resolution rendering, yet the 4K Ultra result of 61 FPS shows that even this monster GPU struggles with the most demanding preset at 4K. This implies that Pc Building Simulator's Ultra settings may include effects like high-resolution shadows, ambient occlusion, and post-processing that are particularly taxing on GPU compute.

How This Combo Ranks

The combination of Intel Core Ultra 7 155H and NVIDIA GeForce RTX 5090 ranks 578th out of 3002 tested combos in Pc Building Simulator, placing it in the top 19% of all configurations. This is a strong showing, but not exceptional given the GPU's raw power. The rank suggests that the CPU is holding back the overall performance, as the RTX 5090 alone would likely rank much higher if paired with a top-tier desktop processor. The Core Ultra 7 155H's mobile nature (28 W TDP, BGA socket) means it cannot deliver the sustained multi-core performance of a high-end desktop chip, and this appears to cap the system's potential in this game.

The combo rank of 578 out of 3002 means that approximately 2424 other combinations outperform this setup, which is surprising given the RTX 5090's flagship status. This discrepancy highlights the importance of CPU-GPU balance: the data implies that in Pc Building Simulator, many lower-tier GPUs paired with stronger desktop CPUs will achieve higher average frame rates, particularly at 1080p where the CPU is more likely to be the bottleneck. The fact that the RTX 5090's nearest GPU rivals include the Tesla P100 (a 2016-era professional card) further emphasizes that raw GPU compute is not the sole determinant of gaming performance in this title.

The rank also reflects the measured data's consistency: the combo delivers 345 FPS at 1080p Low and 61 FPS at 4K Ultra, a range that spans from extreme overkill to barely playable. This wide performance envelope means that the combo's average performance, and thus its rank, is pulled down by the 4K results. For players targeting 1080p or 1440p, this combo would likely rank much higher in practical terms, but the database's ranking accounts for all measured settings and resolutions equally.

FAQ

Q: What is the best resolution to play Pc Building Simulator with this hardware?

A: Based on the measured data, 1440p with Medium settings provides the best balance of visual quality and performance, delivering 173 FPS average with a minimum of 147 FPS.

Q: Does the RTX 5090's 32 GB VRAM make a difference in this game?

A: The measured data shows that 4K Ultra results in 61 FPS average, which is playable but borderline. The 32 GB GDDR7 memory with 1.79 TB/s bandwidth likely prevents texture streaming issues at 4K, as the game must render detailed component models. However, the data does not include VRAM usage metrics, so this is an inference from the GPU's specifications.

Q: Is the Intel Core Ultra 7 155H a bottleneck for the RTX 5090?

A: The data suggests yes, particularly at 1080p. The combo achieves 345 FPS at 1080p Low, but the CPU's PassMark single-thread score of 3468 and Cinebench R23 single-core score of 1743 indicate modest single-thread performance. Since the combo ranks 578th out of 3002, many other CPU+GPU combinations achieve better overall performance, implying the mobile CPU limits the GPU's potential.

Q: How does this combo compare to the RTX 5090's nearest GPU rivals?

A: The RTX 5090's nearest rivals are the NVIDIA Tesla P100 PCIe 16 GB (deltaPct 0.3%), Tesla P100 PCIe 12 GB (deltaPct 0.6%), AMD Radeon RX 6850M XT (deltaPct 1.1%), and AMD Radeon Pro Vega 64X (deltaPct -1.4%). These deltas are all within 1.4% in synthetic benchmarks, but the RTX 5090's 32 GB VRAM and modern architecture make it more suitable for 4K gaming.

Q: What is the frame rate difference between Low and Ultra settings at 1440p?

A: At 1440p, Low delivers 244 FPS average while Ultra delivers 116 FPS average, a difference of 128 FPS. Medium sits between at 173 FPS with a documented minimum of 147 FPS, making it the only preset at this resolution with min/max data available.

Q: Is this combo suitable for 4K gaming in Pc Building Simulator?

A: Yes, but with caveats. The 4K Medium preset delivers 90 FPS average with a 77 FPS minimum, which is smooth. The 4K High preset drops to 64 FPS, and Ultra falls to 61 FPS. For consistent 60+ FPS gameplay, Medium is the recommended 4K preset based on the measured data.

Measured FPS Breakdown

At 1920x1080, the measured frame rates span a wide range. Low settings produce 345 FPS average, Medium delivers 274 FPS with a minimum of 233 FPS and maximum of 315 FPS, High reaches 193 FPS, and Ultra manages 184 FPS. The gap between Medium and High is 81 FPS, while the gap between High and Ultra is only 9 FPS, suggesting diminishing returns from High to Ultra at this resolution. The Medium preset's documented frame range (233-315 FPS) indicates stable performance, while the lack of min/max data for other presets means only average FPS can be compared.

At 2560x1440, the data shows Low at 244 FPS, Medium at 173 FPS (min 147, max 199), High at 122 FPS, and Ultra at 116 FPS. The Medium preset's minimum of 147 FPS is notable because it remains above the refresh rate of most 1440p monitors (typically 144 Hz), meaning this preset should provide a tear-free experience on standard displays. The drop from Medium to High is 51 FPS, while High to Ultra is only 6 FPS, again showing that High offers minimal visual improvement over Ultra at this resolution.

At 3840x2160, the measured FPS values are: Low at 127 FPS, Medium at 90 FPS (min 77, max 104), High at 64 FPS, and Ultra at 61 FPS. The Medium preset's min/max range of 77-104 FPS shows a 27 FPS variance, which is the largest spread among all Medium presets across resolutions. The difference between High and Ultra at 4K is only 3 FPS, making Ultra essentially identical to High in performance terms. The 4K Low setting at 127 FPS is the only 4K preset that comfortably exceeds 120 FPS, which could matter for high-refresh-rate 4K monitors.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals a consistent pattern across all settings. At Low settings, the FPS drops from 345 at 1080p to 244 at 1440p (a 29% reduction), then to 127 at 4K (a 63% reduction from 1080p). At Medium settings, the drop is from 274 at 1080p to 173 at 1440p (37% reduction), then to 90 at 4K (67% reduction). At High settings, the drop is from 193 to 122 (37% reduction) to 64 (67% reduction). At Ultra settings, the drop is from 184 to 116 (37% reduction) to 61 (67% reduction).

The consistent 37% reduction from 1080p to 1440p across Medium, High, and Ultra settings is striking, as is the consistent 67% reduction from 1080p to 4K for those same presets. This uniformity suggests that the performance scaling is determined primarily by pixel count rather than preset complexity. The 1440p resolution has 78% more pixels than 1080p, and the 4K resolution has 300% more pixels, so the FPS drops roughly track the pixel count increases, indicating a GPU-bound scenario where the rendering workload scales linearly with resolution.

However, the Low preset shows a different scaling pattern: a 29% reduction from 1080p to 1440p and a 63% reduction to 4K. This shallower drop suggests that at Low settings, the workload is less GPU-bound and more CPU-limited, particularly at 1080p where the 345 FPS result may be capped by the processor's single-thread performance. The fact that Low scaling deviates from the other presets implies that at higher settings, the GPU is the primary limiting factor, while at Low settings, the CPU begins to assert its influence. This interpretation aligns with the combo's overall rank of 578 out of 3002, which reflects the CPU's inability to fully leverage the RTX 5090's power at lower resolutions and settings.
