Pc Building Simulator

Pc Building Simulator, a simulation title focused on PC assembly rather than high-octane action, proves to be remarkably forgiving on the Intel Core Ultra 7 155H and NVIDIA GeForce RTX 4070 combination. The data shows this pairing is capable of delivering excellent frame rates across all tested resolutions, with performance scaling predictably from 1080p to 4K. The RTX 4070's 12 GB of VRAM and the Ultra 7 155H's 16-core configuration ensure that the game runs smoothly, though the performance headroom at lower resolutions suggests the CPU becomes a more significant factor as the GPU load decreases.

Resolution Scaling

The measured FPS data reveals a clear and consistent scaling pattern as resolution increases from 1920x1080 to 3840x2160. At the "Ultra" preset, the average frame rate drops from 127 FPS at 1080p to 80 FPS at 1440p, and finally to 42 FPS at 4K. This represents a substantial 67% reduction in performance from the lowest to the highest resolution, indicating that the RTX 4070's rendering workload is the primary bottleneck at 4K. The GPU's 504.2 GB/s memory bandwidth and 29.15 TFLOPS of FP32 compute are heavily taxed by the pixel count at 3840x2160, causing the frame rate to fall below the 60 FPS threshold for smooth gameplay.

The scaling from 1440p to 4K is particularly steep, with the "High" preset showing an 84 FPS average at 2560x1440 falling to 44 FPS at 3840x2160. This 47.6% drop is more pronounced than the 36.8% reduction seen when moving from 1080p to 1440p at the same settings, where the average goes from 133 FPS to 84 FPS. This non-linear scaling suggests that the RTX 4070's 192-bit memory bus and 12 GB of GDDR6X VRAM become increasingly stressed as resolution climbs, with the memory subsystem struggling to feed the GPU's 5888 shading units at 4K resolutions.

Interestingly, the "Low" preset shows the most dramatic resolution scaling, with the average frame rate dropping from 266 FPS at 1080p to 168 FPS at 1440p and then to 88 FPS at 4K. The 4K Low result is only 33.1% of the 1080p Low figure, which indicates that even at minimal settings, the GPU's fill rate and memory bandwidth are the limiting factors. At 1080p Low, the frame rate is so high that the CPU's 22 threads and 4.80 GHz boost clock are likely the constraining element, as the GPU has ample headroom to render frames faster than the processor can submit draw calls.

The data shows that this combo is best suited for 1080p and 1440p gaming, where even the most demanding "Ultra" preset maintains averages above 80 FPS. At 4K, users will need to compromise on settings, as the "Medium" preset with its 62 FPS average and 53 FPS minimum provides the only playable experience at that resolution, while "High" and "Ultra" dip to 44 FPS and 42 FPS respectively. The RTX 4070's 158.4 GPixel/s pixel rate and 455.4 GTexel/s texture rate are simply not sufficient to maintain high frame rates at 3840x2160 with maximum quality settings.

Settings Recommendations

The measured data provides clear guidance on the optimal settings for this hardware combination, with the "Medium" preset emerging as the best balance of visual quality and performance. At 1920x1080, the Medium preset delivers a 189 FPS average with a 160 FPS minimum, which is more than sufficient for any display refresh rate. The 1440p Medium result of 119 FPS with a 101 FPS minimum is equally impressive, offering a smooth experience on high-refresh-rate monitors. Even at 4K, the Medium preset's 62 FPS average and 53 FPS minimum keeps gameplay fluid, though it is the only 4K setting that achieves this.

The "High" preset offers a marginal visual upgrade over Medium but comes at a significant performance cost. At 1080p, High averages 133 FPS, which is 29.6% lower than Medium's 189 FPS, while at 1440p the gap widens to 29.4% with 84 FPS versus 119 FPS. The 4K High result of 44 FPS is 29.0% below the Medium figure, and this drop pushes the experience below the 60 FPS target. Given that the visual differences between Medium and High in a simulation game like Pc Building Simulator are likely subtle, the performance penalty makes High a poor choice for this hardware.

Ultra settings are only recommended for 1080p gaming, where the 127 FPS average remains playable, though it is 32.8% lower than Medium. At 1440p, the Ultra preset's 80 FPS average is still respectable but represents a 32.8% reduction from Medium's 119 FPS. The 4K Ultra result of 42 FPS is the worst measured performance in the entire dataset, and this setting should be avoided entirely at that resolution. The 12 GB VRAM capacity is not the limiting factor here, as the game's texture requirements are modest, but the GPU's compute and memory bandwidth are insufficient for Ultra settings at 4K.

For users prioritizing frame rate, the "Low" preset at 1440p provides a 168 FPS average, which is 41.2% higher than Medium and represents the best performance-to-quality ratio for competitive or fast-paced gameplay. The 1080p Low result of 266 FPS is the highest measured in the dataset, though this exceeds the refresh rate of most monitors, making the extra performance moot. The data clearly shows that Medium is the sweet spot for this combo, offering playable frame rates at all resolutions while maintaining a reasonable level of visual fidelity.

GPU Role

The NVIDIA GeForce RTX 4070's specifications directly explain the observed performance characteristics in Pc Building Simulator. With 12 GB of GDDR6X VRAM on a 192-bit bus, the GPU provides 504.2 GB/s of memory bandwidth, which is sufficient for this game's assets at all tested resolutions. The fact that VRAM capacity does not appear to be a bottleneck is evidenced by the relatively modest performance drop between Medium and High settings, which would be more pronounced if the GPU were running out of memory. The 5888 shading units and 184 texture mapping units deliver a texture rate of 455.4 GTexel/s, which is more than adequate for the game's relatively simple geometry and textures.

The GPU's clock speeds play a significant role in its performance, with a base clock of 1920 MHz and a boost clock of 2475 MHz. These high clocks, combined with the Ada Lovelace architecture's efficiency, allow the RTX 4070 to maintain strong frame rates even at 1440p with medium settings. The 29.15 TFLOPS of FP32 compute power is the primary driver of the 119 FPS average seen at 1440p Medium, as the game's simulation logic is not particularly demanding on the GPU's compute units. The 46 RT cores and 184 tensor cores are present but largely underutilized, as Pc Building Simulator does not employ ray tracing or DLSS features in the measured configurations.

The GPU's 81st percentile ranking among all GPUs and its average benchmark score of 37648 indicate that it is a solid mid-range performer, though it is not a top-tier card. Its nearest rival, the NVIDIA Tesla P4, scores nearly identically at 37628 with a deltaPct of 0.1%, while the AMD Radeon RX Vega 56 trails by 0.4% with a score of 37507. The RTX 4080 Mobile scores 38135, which is 1.3% higher, showing that the desktop RTX 4070 is closely matched with high-end mobile parts. This positioning explains why the GPU struggles at 4K Ultra, as its performance is comparable to a mobile chip rather than a flagship desktop card.

The GPU's pixel rate of 158.4 GPixel/s is a key factor in the 4K performance drop. At 3840x2160, the GPU must fill approximately 8.3 million pixels per frame, and at 42 FPS on Ultra, this translates to roughly 348.5 million pixels per second, which is well below the theoretical maximum. The memory bandwidth of 504.2 GB/s also becomes a constraint at 4K, as the higher resolution demands more texture fetches and frame buffer writes. The 200 W TDP and dual-slot design are consistent with a mid-range GPU, and the 550 W suggested PSU indicates that this card does not require excessive power delivery.

Measured FPS Breakdown

The complete dataset of measured frame rates provides a comprehensive picture of this combo's gaming performance. At 1920x1080, the frame rates range from a maximum of 266 FPS on Low to a minimum of 127 FPS on Ultra. The Medium preset records a 189 FPS average with a 160 FPS minimum and 217 FPS maximum, showing excellent consistency with only a 30.1% variance between the lowest and highest frame times. The High preset averages 133 FPS, which is 29.3% lower than Medium, while Ultra drops another 4.5% to 127 FPS, indicating diminishing returns from High to Ultra.

At 2560x1440, the performance scales down proportionally. The Low preset achieves a 168 FPS average, which is 36.8% lower than the 1080p Low result, while Medium delivers 119 FPS with a 101 FPS minimum and 137 FPS maximum. The High preset averages 84 FPS, and Ultra drops to 80 FPS, representing only a 4.8% difference between these two settings. This suggests that at 1440p, the GPU's compute and memory resources are becoming saturated, and the visual improvements from High to Ultra have minimal impact on frame rate.

The 3840x2160 results show the most significant performance degradation. The Low preset averages 88 FPS, which is 47.6% lower than the 1440p Low figure, while Medium averages 62 FPS with a 53 FPS minimum and 72 FPS maximum. The High preset drops to 44 FPS, and Ultra is nearly identical at 42 FPS, showing only a 4.5% difference. The 4K Medium result is the only playable option at this resolution, as the 53 FPS minimum ensures that frame times remain below the 18.9 ms threshold for 60 FPS gameplay, though just barely.

The data reveals that the RTX 4070's performance ceiling is reached at 4K with Medium settings, as the GPU cannot maintain 60 FPS at higher presets. The 1080p and 1440p results show that this combo is capable of high-refresh-rate gaming, with the 1440p Medium result of 119 FPS being particularly noteworthy for a 1440p 120Hz monitor. The 1080p Medium minimum of 160 FPS guarantees a smooth experience on even the fastest gaming displays, and the 217 FPS maximum provides ample headroom for variable refresh rate technologies.

How This Combo Ranks

The Intel Core Ultra 7 155H and RTX 4070 combination ranks 1577 out of 3002 tested combos in Pc Building Simulator, placing it in the 52.5th percentile. This means that roughly half of all tested hardware combinations perform better in this game, which is a surprisingly low ranking given the strong absolute performance numbers. The ranking suggests that many other CPU-GPU pairings, likely including those with more powerful desktop GPUs or higher-end CPUs, achieve higher frame rates in this simulation title.

The CPU's 83rd percentile ranking among all processors and its average benchmark score of 32697 indicate that the Ultra 7 155H is a strong mobile processor, but it is not a top-tier desktop part. Its nearest rival, the Intel Core i5-14600T, scores 32707 with a deltaPct of 0%, showing that the Ultra 7 155H is essentially tied with a mid-range desktop chip. The AMD Ryzen AI 7 PRO 360 scores 32662, a 0.1% difference, while the AMD Ryzen 5 7400F and Ryzen 7 PRO 6850H score 32750 and 32812 respectively, with the latter being 0.4% faster.

The combo's mid-pack ranking is likely influenced by the CPU's mobile nature and 28 W TDP, which limits sustained performance compared to desktop processors with higher power budgets. Even though the Ultra 7 155H has 16 cores and 22 threads, its 3.80 GHz base clock and 4.80 GHz boost clock are lower than many desktop CPUs, and the 24 MB shared L3 cache may not be sufficient for the game's simulation logic. The comboRankInGame of 1577 out of 3002 means that users seeking the absolute highest frame rates in Pc Building Simulator would need to consider more powerful desktop hardware.

However, it is important to note that the ranking does not reflect the playability of the experience, as the measured FPS data shows that this combo delivers smooth performance at all tested settings and resolutions. A 52.5th percentile ranking is respectable for a mobile CPU paired with a mid-range desktop GPU, and the absolute frame rates are more than adequate for a simulation game that does not require twitch reflexes. The ranking should be interpreted as an indication that this combo is average among tested configurations, not that it provides a poor experience.

CPU Role

The Intel Core Ultra 7 155H's 16 cores and 22 threads are more than sufficient for Pc Building Simulator's demands, as evidenced by the high frame rates at 1080p where the GPU is not the limiting factor. The CPU's 3.80 GHz base clock and 4.80 GHz boost clock provide strong single-threaded performance, which is critical for simulation games that often rely on a single main thread for game logic. The 24 MB shared L3 cache helps reduce memory latency, and the 89.6 GB/s memory bandwidth ensures that the CPU can quickly access game data.

The CPU's benchmark scores reveal its capabilities, with a Cinebench R23 multi-core score of 15028 and a single-core score of 1743. The PassMark single-thread score of 3468 places it in the 83rd percentile among all CPUs, indicating that its single-core performance is above average. The multi-threaded PassMark score of 24873 shows strong multi-core performance, which is beneficial for background tasks but less critical for Pc Building Simulator's gameplay. The CPU's 112 KB L1 cache per core and 2 MB L2 cache per core provide ample fast storage for frequently accessed data.

The CPU's role becomes more apparent at lower resolutions where the GPU has headroom. At 1080p Low, the 266 FPS average is likely CPU-limited, as the GPU could theoretically render more frames if the CPU could submit draw calls faster. The 4.80 GHz boost clock helps here, but the mobile CPU's 28 W TDP limits its sustained clock speeds under heavy load. The 16 cores are not all utilized equally in this game, as the simulation logic is likely single-threaded, making the single-core performance more important than the core count.

The CPU's 83rd percentile ranking and average benchmark score of 32697 place it in line with the Intel Core i5-14600T, which scores 32707, and slightly above the AMD Ryzen AI 7 PRO 360 at 32662. The AMD Ryzen 7 PRO 6850H scores 32812, which is 0.4% higher, showing that the Ultra 7 155H is competitive with other mid-range processors. The CPU's 7 nm process node and Meteor Lake architecture provide good efficiency, but the mobile design means it cannot match the performance of desktop CPUs with higher TDPs. For Pc Building Simulator, the CPU is not the bottleneck at 1440p and 4K, but at 1080p with low settings, it does limit the maximum achievable frame rate.
