Pc Building Simulator

The Intel Core Ultra 7 155H paired with the NVIDIA GeForce RTX 4090 delivers a performance profile in Pc Building Simulator that is defined by extreme GPU headroom and a clear CPU bottleneck at lower resolutions. This combo ranks 696th out of 3002 tested combinations, placing it in the top 23% of all systems. The data shows that while the RTX 4090 provides overwhelming frame rates, the mobile-class Ultra 7 155H limits the system from reaching its full potential, particularly at 1080p.

How This Combo Ranks

The combination of the Intel Core Ultra 7 155H and NVIDIA GeForce RTX 4090 achieves a rank of 696 out of 3002 tested combos in Pc Building Simulator. This places the system in the 77th percentile of all configurations, which is a strong result but not elite. The ranking reflects a significant imbalance: the GPU is a top-tier desktop part, while the CPU is a mobile-focused processor with a 28W TDP. The benchmark results show that the system is capable of very high frame rates, yet the CPU consistently holds back the GPU from delivering its maximum possible output.

Looking at the individual component benchmarks, the CPU scores an average of 32697, which places it in the 83rd percentile of all CPUs. Its nearest rivals include the Intel Core i5-14600T with an average score of 32707 (a 0% delta), the AMD Ryzen AI 7 PRO 360 at 32662 (0.1% faster), and the AMD Ryzen 5 7400F at 32750 (0.2% slower). These extremely tight margins show that the Ultra 7 155H is a mid-pack performer in synthetic CPU tests. Meanwhile, the RTX 4090 achieves an average benchmark score of 60347, ranking in the 88th percentile of all GPUs. Its nearest rivals include the Intel Arc Pro A60 at 60326 (0% delta) and the AMD Radeon Pro Vega 48 at 60140 (0.3% faster), which are far less powerful gaming cards. This disparity in component class explains why the combo's in-game rank (696th) is lower than either component's individual percentile ranking.

The in-game rank is likely dragged down by CPU-limited scenarios. While the GPU can generate massive frame counts, the CPU cannot feed it fast enough at lower resolutions, capping the system's overall performance. The result is a combo that performs like a high-end system but leaves performance on the table. The data indicates that the RTX 4090 alone would place much higher if paired with a more powerful desktop CPU, but with this mobile processor, the system settles into the upper-mid tier of all tested combos.

Settings Recommendations

The measured FPS data provides clear guidance on the optimal settings preset for this combo. Across all three tested resolutions, the Low preset delivers the highest average frame rates, but it is not always the best choice for a smooth experience. The Medium preset offers a better balance between visual quality and performance, and the data shows it is the recommended starting point.

At 1920x1080, the Low preset achieves an average of 345 FPS, while Medium delivers 262 FPS, High hits 185 FPS, and Ultra drops to 176 FPS. The Medium preset provides 76% of the Low preset's frame rate while offering noticeably better visuals. The measured minimum FPS at Medium is 222, which is still far above any display's refresh rate. There is no reason to use Low at this resolution because the CPU becomes the limiting factor; the frame rate jump from Medium to Low is large, but the system already exceeds 200 FPS on Medium. For smooth 60Hz or even 144Hz gaming, Medium is the most efficient choice.

At 2560x1440, the pattern shifts. Low averages 233 FPS, Medium drops to 165 FPS, High to 117 FPS, and Ultra to 111 FPS. The Medium preset remains the sweet spot, offering a 165 FPS average with a minimum of 140 FPS. This is sufficient for high-refresh-rate monitors. The High preset at 117 FPS is also viable for 60Hz displays, but Medium provides headroom for frame drops without sacrificing much visual fidelity.

At 3840x2160, the situation changes dramatically. Low averages 122 FPS, but Medium drops to 86 FPS, High to 61 FPS, and Ultra to 58 FPS. Here, the Medium preset is the strongest recommendation, as it maintains an average above 60 FPS while providing much better image quality than Low. The High preset at 61 FPS is right at the 60Hz boundary, which risks noticeable stutter if frame times spike. The Ultra preset at 58 FPS is below the 60 FPS target and should be avoided. The measured data for 4K Medium shows a minimum of 73 FPS and a maximum of 99 FPS, indicating a stable frame time distribution. For the best experience across all resolutions, Medium is the recommended preset, with High being a fallback for 1080p and 1440p users who prefer visuals over headroom.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals a clear picture of the system's bottleneck. At the Low preset, the average frame rate drops from 345 FPS at 1080p to 233 FPS at 1440p (a 32% decrease) and then to 122 FPS at 4K (a 65% decrease from 1080p). This scaling is not linear, which indicates that the CPU is the limiting factor at lower resolutions. At 1080p Low, the CPU cannot process frames fast enough to keep the GPU busy, so the frame rate is capped by the processor's single-thread performance. As resolution increases, the GPU takes on more work, and the frame rate drops proportionally with the pixel count.

At the Medium preset, the scaling is similar: 262 FPS at 1080p, 165 FPS at 1440p (a 37% drop), and 86 FPS at 4K (a 67% drop). The fact that the percentage drop from 1080p to 1440p is larger at Medium (37%) than at Low (32%) suggests that the GPU is starting to become more involved, but the CPU still holds back performance at 1080p. The 4K results show a more GPU-bound scenario, as the frame rate scales more closely with the pixel count increase.

The High and Ultra presets tell a different story. At High, the frame rate drops from 185 FPS at 1080p to 117 FPS at 1440p (a 37% drop) and then to 61 FPS at 4K (a 67% drop). At Ultra, the numbers are 176 FPS, 111 FPS, and 58 FPS, respectively. These settings are more GPU-intensive, and the scaling is more consistent. The data suggests that at 4K, the system becomes GPU-bound, as the RTX 4090's raw power is taxed by the higher resolution and settings. The CPU bottleneck is most pronounced at 1080p, where the Ultra 7 155H's modest single-core performance limits the system to 176-345 FPS depending on the preset, while the GPU could theoretically output much more.

This analysis indicates that the limiting component shifts with resolution. At 1080p, the CPU is the bottleneck, capping frame rates at levels far below what the RTX 4090 can achieve. At 4K, the GPU becomes the primary limiter, and the system's frame rates align more closely with what the GPU alone can deliver. Users targeting high refresh rates at 1080p will find the CPU holding back performance; those playing at 4K will get the most balanced experience.

Measured FPS Breakdown

The measured FPS data provides exact figures for each resolution and settings preset. At 1920x1080, the Low preset delivers an average of 345 FPS, which is the highest frame rate recorded in this test. The Medium preset averages 262 FPS with a minimum of 222 and a maximum of 301 FPS. The High preset averages 185 FPS, and the Ultra preset averages 176 FPS. The gap between Low and Medium is 83 FPS, while the gap between High and Ultra is only 9 FPS, showing diminishing returns at the highest settings.

At 2560x1440, the Low preset averages 233 FPS. The Medium preset averages 165 FPS with a minimum of 140 and a maximum of 190 FPS. The High preset averages 117 FPS, and the Ultra preset averages 111 FPS. The frame rate difference between High and Ultra narrows to just 6 FPS, suggesting that Ultra offers no meaningful performance penalty at this resolution.

At 3840x2160, the Low preset averages 122 FPS, which is still above the 60 FPS threshold for smooth play. The Medium preset averages 86 FPS with a minimum of 73 and a maximum of 99 FPS. The High preset averages 61 FPS, right at the boundary of acceptable performance, and the Ultra preset averages 58 FPS, which is below the 60 FPS target. The data shows a steep drop from Low to Medium (36 FPS) and a moderate drop from Medium to High (25 FPS), with only a 3 FPS difference between High and Ultra.

The minimum FPS data is only available for the Medium preset at each resolution: 222 FPS at 1080p, 140 FPS at 1440p, and 73 FPS at 4K. These minimums indicate that the frame pacing is stable, with no severe drops below the average. The maximum FPS values for Medium are 301 at 1080p, 190 at 1440p, and 99 at 4K, showing a consistent performance envelope. The lack of min/max data for other presets limits deeper analysis, but the averages alone provide a clear performance hierarchy.

CPU Role

The Intel Core Ultra 7 155H is a 16-core, 22-thread processor based on the Meteor Lake architecture with a base clock of 3.80 GHz and a boost clock of 4.80 GHz. It features a 24 MB shared L3 cache and a 7 nm process node. The CPU's benchmark scores show strong multi-threaded performance, with a Cinebench R23 multi-core score of 15028 and a single-core score of 1743. The PassMark multi-thread score is 24873, while the single-thread score is 3468.

In Pc Building Simulator, the CPU's role is primarily to handle game logic, simulation calculations, and frame pacing. The game is not heavily multi-threaded, relying more on single-core performance. The Ultra 7 155H's single-core score of 1743 in Cinebench R23 places it in the 83rd percentile of all CPUs, which is decent but not exceptional for a modern processor. The data shows that this single-thread performance is the limiting factor at 1080p, where the system cannot exceed 345 FPS even on Low settings.

The CPU's 28W TDP indicates it is designed for mobile use, which explains its modest performance compared to desktop processors. The boost clock of 4.80 GHz helps in lightly-threaded workloads, but the power constraints prevent sustained high clocks. The 16 cores and 22 threads provide ample multi-threading for other tasks, but in this game, the extra cores go unused, as the simulation is likely single-thread-bound.

The L3 cache of 24 MB is shared across all cores, which helps with data locality in simulation games. The memory bandwidth of 89.6 GB/s, while adequate, is lower than what high-end desktop CPUs offer, potentially contributing to the bottleneck at high frame rates. The CPU's integrated graphics, Arc Xe-LPG 128EU, are irrelevant in this test because the system uses the dedicated RTX 4090.

Overall, the CPU's role in this combo is to provide adequate processing power for the game's logic while feeding the GPU. The data indicates that it succeeds in maintaining playable frame rates at 4K, but it fails to unlock the RTX 4090's full potential at lower resolutions. For users prioritizing 1080p high-refresh gaming, a more powerful desktop CPU would be necessary, but for 4K gaming, this mobile processor is sufficient.
