CPU Role

The Intel Core Ultra 7 155H is a 16-core, 22-thread processor based on the Meteor Lake architecture, built on Intel’s 7 nm process. It features a base clock of 3.80 GHz and a boost clock of 4.80 GHz, with a 24 MB shared L3 cache. In synthetic benchmarks, this CPU performs strongly, achieving a Cinebench R23 multicore score of 15028 and a single-core score of 1743. Its average benchmark score of 32697 places it in the 83rd percentile of all CPUs, showing that its processing power is a significant asset.

The CPU’s nearest rivals illustrate its position. It performs within 0.2% of the AMD Ryzen 5 7400F (32750) and within 0.4% of the AMD Ryzen 7 PRO 6850H (32812). It also edges out the AMD Ryzen AI 7 PRO 360 by 0.1% (32662 vs 32697). This indicates that the processor is not a bottleneck in this system; it has ample headroom for gaming workloads.

In Rust, which is known for its simulation and entity-update logic, the CPU’s 22 threads and high boost clock should theoretically provide a solid foundation. However, the measured FPS data shows that the system’s performance is not CPU-limited. For instance, at 1080p Low, the CPU is capable of feeding the GPU enough data to produce 64 FPS. If the CPU were the primary constraint, we would expect to see similar frame rates across different resolutions. Instead, the FPS drops dramatically as resolution increases, which points to the GPU as the limiting factor. The CPU’s strong Passmark multithread score of 24873 and integer math score of 86870 suggest it can handle the complex calculations Rust requires, but the graphics pipeline prevents it from fully utilizing this capability.

GPU Role

The AMD Radeon 880M is an integrated GPU (IGP) based on the RDNA 3.5 architecture, built on TSMC’s 4 nm process. It operates with a base clock of 400 MHz and a boost clock of 2900 MHz, featuring 768 shading units and 12 ray tracing cores. Its memory is system-shared, with bandwidth and size dependent on the system’s RAM configuration. The GPU’s synthetic performance is modest; it achieves a 3DMark Steel Nomad DX12 score of 535 and a Passmark G3D score of 7615. Its average benchmark score of 8436 places it in the 43rd percentile of all GPUs.

The GPU’s nearest rivals are older discrete mobile parts, which contextualizes its performance level. It is 0.3% faster than the NVIDIA GeForce MX330 (8458) and 1.3% faster than the AMD Radeon R9 M375X (8325). It is also 0.1% ahead of the NVIDIA GeForce GTX 675MX (8427). This places the 880M in the range of entry-level discrete GPUs from several generations ago, which is a significant limitation for a demanding title like Rust.

The benchmark results in Rust confirm this limitation. At 1080p Low, the GPU manages 64 FPS, but this falls to 36 FPS at High. The situation worsens at higher resolutions: at 1440p Low, the average drops to 44 FPS, and at 4K Low, it falls to 26 FPS. The GPU’s peak pixel rate of 46.40 GPixel/s and texture rate of 139.2 GTexel/s are insufficient for the high-resolution rendering that Rust demands. The data clearly shows that the 880M is the constraining component, as the FPS scales inversely with the number of pixels rendered, regardless of the CPU’s capabilities.

Settings Recommendations

The measured FPS data provides a clear picture of which settings presets are viable for this combo. The primary goal is to maintain a playable frame rate, and the data shows that only the Low preset achieves this consistently at 1080p. At 1920x1080, the Low preset produces an average of 64 FPS, which is the only preset at any resolution to exceed 60 FPS. The Medium preset at 1080p yields 43 FPS average with a minimum of 37 FPS, which is playable but may feel less smooth in fast-paced scenarios.

At 1440p, the Low preset delivers 44 FPS average, which is borderline playable. The Medium preset drops to 30 FPS average with a minimum of 25 FPS, which is likely to be a stuttery experience. The High and Ultra presets at 1440p produce 25 FPS and 19 FPS averages respectively, which are not recommended for active gameplay.

The 4K resolution is not viable for this system. Even the Low preset at 3840x2160 only achieves 26 FPS average, and the Ultra preset falls to 11 FPS average. The data suggests that for the best experience, users should run the game at 1080p with the Low preset to achieve smooth performance. If visual fidelity is a priority, the Medium preset at 1080p offers a compromise, but the frame rate drops by approximately 33% compared to Low. The High and Ultra presets should be avoided at all resolutions, as they push the GPU beyond its limits.

How This Combo Ranks

The Intel Core Ultra 7 155H + AMD Radeon 880M combo ranks 2878 out of 2953 tested combinations in Rust. This places it in the bottom 2.5% of all tested systems, indicating that it is not suited for this game. The rank reflects the significant GPU bottleneck, as the CPU’s strong synthetic performance is negated by the integrated graphics’ inability to render the game at acceptable frame rates.

The rank is particularly poor considering the CPU’s capabilities. The Core Ultra 7 155H is a high-end mobile processor, but the Radeon 880M is an integrated solution that competes with decade-old discrete GPUs. This mismatch means the system’s overall gaming performance is limited by its weakest link. In comparison to other combos in the database, this pairing falls far behind even modest discrete GPU configurations. The data suggests that users of this combo would need to significantly lower resolution and settings to achieve playable performance, which is reflected in its low rank. The rank of 2878 out of 2953 is a clear indicator that this is not a gaming-focused configuration.

Measured FPS Breakdown

The measured FPS data provides a comprehensive look at the combo’s performance across three resolutions and four settings presets. At 1920x1080, the Low preset achieves 64 FPS average, the highest of any configuration. The Medium preset averages 43 FPS, with a minimum of 37 FPS and a maximum of 50 FPS. The High preset averages 36 FPS, and the Ultra preset averages 28 FPS.

At 2560x1440, the Low preset averages 44 FPS. The Medium preset averages 30 FPS, with a minimum of 25 FPS and a maximum of 34 FPS. The High preset averages 25 FPS, and the Ultra preset averages 19 FPS. The frame rate at 1440p Low is notably higher than 1080p High, demonstrating that resolution has a more significant impact on performance than the graphics preset.

At 3840x2160, the Low preset averages 26 FPS. The Medium preset averages 18 FPS, with a minimum of 15 FPS and a maximum of 20 FPS. The High preset averages 15 FPS, and the Ultra preset averages 11 FPS. The 4K results are uniformly poor, with no preset achieving a playable frame rate. The data shows a clear trend: for every resolution, the Low preset provides the best performance, while the Ultra preset provides the worst. The differences between presets are consistent, with the Low preset typically delivering more than double the frame rate of the Ultra preset.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals the nature of the bottleneck in this system. At Low settings, the average frame rate drops from 64 FPS at 1080p to 44 FPS at 1440p, a reduction of 31.25%. When moving to 4K, the frame rate drops to 26 FPS, which is a 59.4% reduction from 1080p. This scaling pattern is characteristic of a GPU-bound workload, where the number of pixels being rendered directly impacts performance.

The Medium settings show a similar trend. The average FPS at 1080p is 43, dropping to 30 at 1440p (a 30.2% reduction) and 18 at 4K (a 58.1% reduction). The High settings follow the same pattern: 36 FPS at 1080p, 25 at 1440p (a 30.6% reduction), and 15 at 4K (a 58.3% reduction). The consistency of these percentage drops across different settings presets indicates that the GPU’s fill rate is the limiting factor, rather than the specific game settings.

This scaling behavior confirms that the AMD Radeon 880M is the primary constraint. The CPU’s performance is sufficient to handle the game’s logic at 1080p, but as the resolution increases, the GPU’s pixel throughput becomes the bottleneck. The 4K results are particularly telling, as the frame rate drops below 30 FPS even at Low settings, making the game unplayable. The data suggests that the system is best utilized at 1080p, where the GPU can still provide a playable experience at lower settings. The resolution scaling analysis shows that there is no headroom for higher resolutions with this combo.
