Pc Building Simulator

Pc Building Simulator presents a unique stress case for the Intel Core Ultra 7 155H and AMD Radeon 880M combination, where the integrated graphics solution is pushed to its absolute limit. The measured frame rates across resolutions reveal a system that is fundamentally GPU-bound, with the CPU’s substantial multi-core capabilities largely sidelined by the demands of the RDNA 3.5 integrated graphics.

Resolution Scaling

The frame rate data shows a dramatic collapse as resolution increases, which is the clearest indicator of where the bottleneck lies. At 1080p with Low settings, the combo achieves 105 FPS, a very playable figure for a simulation title. Scaling up to 1440p Low drops the average to 66 FPS, a 37% reduction from the 1080p result. Moving to 4K Low further reduces the average to 35 FPS, which is less than half of the 1440p figure and only a third of the 1080p performance.

This steep scaling curve is consistent across all quality presets. For example, at Medium settings, the average frame rate falls from 74 FPS at 1080p to 47 FPS at 1440p, and then to 25 FPS at 4K. The pattern is identical for High and Ultra presets, with 4K averages of 17 FPS and 16 FPS respectively, making those configurations effectively unplayable. The consistent percentage drops between resolutions point directly to the GPU as the limiting component; a system with more graphics headroom would show a less severe decline when pixel count increases.

The data suggests that the AMD Radeon 880M simply runs out of pixel throughput as the resolution climbs. The transition from 1080p to 1440p costs roughly 40-45% of the frame rate, which is a massive hit. The jump from 1440p to 4K is even more punishing, with another 50% reduction in performance. This indicates that the integrated GPU’s memory bandwidth, which is system-dependent and shared, becomes a critical constraint at higher resolutions where the demand for texture data and frame buffer space grows exponentially.

GPU Role

The AMD Radeon 880M is the dominant factor in this configuration, and its specifications explain the observed performance ceiling. It is an integrated graphics processor (IGP) based on the RDNA 3.5 architecture, built on a 4 nm process at TSMC. The GPU has a boost clock of 2900 MHz and a base clock of 400 MHz, and it features 768 shading units, 48 texture mapping units, and 16 ROPs. The memory configuration is "System Shared," meaning its bandwidth is entirely dependent on the system’s memory setup, a detail that likely contributes to the severe frame rate drops at 4K.

In synthetic benchmarks, the 880M scores 7615 in Passmark’s G3D test and 8436 as its average benchmark score, placing it in the 43rd percentile of all GPUs. Its nearest rivals in the database include the NVIDIA GeForce GTX 675MX (0.1% faster), the NVIDIA GeForce MX330 (0.3% faster), and the AMD Radeon HD 8870M (0.3% faster). These comparisons show that the 880M is positioned in the lower-midrange tier of graphics hardware, and the measured FPS in Pc Building Simulator aligns with this ranking. The GPU’s DirectX 12 Ultimate support does not translate into high frame rates in this title, as the raw fill rate is insufficient for demanding resolutions.

The FP32 compute performance is rated at 4.454 TFLOPS, which is respectable for an IGP but far below what discrete cards offer. With only 16 ROPs, the pixel fill rate is capped at 46.40 GPixel/s, which is a severe limitation at 4K. For instance, at 4K Ultra, the system manages just 16 FPS, highlighting that the GPU is overwhelmed by the pixel count. The gap between the 1080p Low score of 105 FPS and the 4K Low score of 35 FPS is a 200% difference, underscoring that the GPU’s compute and memory resources are simply not scalable to higher resolutions in this simulation.

CPU Role

The Intel Core Ultra 7 155H is a mobile processor with 16 cores and 22 threads, based on the Meteor Lake architecture built on Intel’s 7 nm process. It has a base clock of 3.80 GHz and a boost clock of 4.80 GHz, with a TDP of 28 W. The cache hierarchy includes 112 KB of L1 per core, 2 MB of L2 per core, and a shared 24 MB of L3 cache. In synthetic CPU tests, it scores 15028 in Cinebench R23 multi-core and 1743 in single-core, placing it in the 83rd percentile of all CPUs.

Its average benchmark score is 32697, which puts it nearly identical to the Intel Core i5-14600T (a 0% delta) and the AMD Ryzen AI 7 PRO 360 (0.1% slower). This indicates that the CPU is more than capable of handling gaming workloads. However, the measured FPS in Pc Building Simulator shows that the CPU’s power is largely untapped. The frame rates are almost entirely dictated by the GPU, as evidenced by the fact that even at 1080p Low, where the CPU has the most room to breathe, the system only reaches 105 FPS.

The benchmark results suggest that the CPU is not the limiting factor. For example, the Passmark multithread score is 24873, and the integer math score is 86870, which are strong numbers. Yet, in this game, the CPU’s role is reduced to feeding the GPU with draw calls and simulation data. The game is a simulation title, which often relies on single-thread performance for game logic, but the Core Ultra 7 155H’s single-thread Passmark score of 3468 is sufficient to avoid bottlenecking at the frame rates observed. The data shows that as resolution increases, the FPS drops proportionally, which would not happen if the CPU were the constraint; in a CPU-bound scenario, the FPS would remain relatively flat across resolutions. Since the FPS halves from 1080p to 4K, the GPU is unequivocally the performance limiter.

Settings Recommendations

The measured rows provide a clear picture of which settings offer the best balance between visual fidelity and playability for this hardware combo. At 1080p, the Low preset delivers the highest average frame rate at 105 FPS, which is ideal for competitive or fast-paced scenes. However, the Medium preset still provides a solid 74 FPS average (with a minimum of 63 FPS), which is likely a better visual experience while remaining well above the 60 FPS threshold. For users who prefer higher fidelity, the High preset at 52 FPS is playable but not smooth, while Ultra drops to 50 FPS.

At 1440p, the options become more constrained. The Low preset is the only one that achieves a consistently smooth experience, with an average of 66 FPS. Medium drops to 47 FPS, which is borderline, and High and Ultra fall to 33 FPS and 32 FPS respectively, making them less desirable for gameplay. The 4K resolution is generally not recommended, as even the Low preset only manages 35 FPS, and Medium, High, and Ultra produce averages of 25 FPS, 17 FPS, and 16 FPS, respectively.

Given the data, the optimal configuration for most users would be the 1080p Medium preset. It offers a 74 FPS average, which is nearly 30% higher than the High preset’s 52 FPS, while providing a reasonable visual upgrade over Low. The minimum FPS of 63 on Medium ensures that frame pacing remains stable, avoiding the stutters that can occur at lower frame rates. For 1440p, the Low preset is the only sensible choice, as it maintains a 66 FPS average, but users should be prepared to accept lower visual details for the higher resolution. Pushing to 4K is not viable, as all presets fall below the playability threshold of 30 FPS, with the best-case scenario being the Low preset at 35 FPS.

How This Combo Ranks

In the database of tested combinations for Pc Building Simulator, this specific pairing of the Intel Core Ultra 7 155H and AMD Radeon 880M ranks 2932 out of 3002 possible combos. This places it in the bottom 2.3% of all tested configurations, which is a poor showing for a modern system. The rank reflects the fact that the integrated GPU is severely underpowered for this game, even though the CPU is in the 83rd percentile of all processors.

The disparity between the CPU’s strong synthetic scores and the combo’s low game rank highlights the importance of GPU selection in gaming. The Core Ultra 7 155H is a high-end mobile processor, but its capabilities are squandered when paired with an IGP. The data shows that the combo’s performance is bottlenecked by the Radeon 880M, which scores in the 43rd percentile of all GPUs. This mismatch means that the system’s overall gaming performance is dragged down to the level of the weakest component.

Compared to other combinations, this setup would likely be outclassed by any system with a discrete entry-level GPU, even if that system had a weaker CPU. The rank of 2932 suggests that the vast majority of other tested combos deliver higher frame rates in this simulation. The only saving grace is that the game is a simulation, which may be less dependent on high frame rates for enjoyment, but the raw numbers indicate that this is not a configuration designed for smooth gameplay at standard resolutions.
