Overpower

The Overpower benchmark results for the Intel Core Ultra 7 155H paired with the AMD Radeon 880M present a clear picture of an integrated graphics solution pushed to its limits. The data indicates this combination is positioned at the lower end of the performance spectrum, ranking 2907th out of 2980 tested combos. The measured FPS across all settings and resolutions shows a system that can manage 1080p gaming at playable levels but struggles significantly as resolution increases. This analysis breaks down the specific performance characteristics, the roles of the CPU and GPU, and provides practical settings guidance based solely on the measured data.

Resolution Scaling

The FPS data reveals a steep performance cliff as resolution scales from 1080p to 4K. At 1920x1080 with Low settings, the combo achieves an average of 60 FPS, which is the only measured point that reaches a smooth 60 FPS threshold. Moving to 2560x1440 at Low settings, the average drops to 54 FPS, a 10% reduction. At 3840x2160 with Low settings, the average falls further to 46 FPS, representing a 23% drop from the 1080p Low result. This pattern strongly indicates that the AMD Radeon 880M's rendering capabilities are the primary bottleneck, as the frame rate degradation is directly proportional to the pixel count increase.

The scaling becomes more pronounced at higher settings. At High settings, the average FPS drops from 35 at 1080p to 31 at 1440p and then to 27 at 4K. The gap between Low and High settings at each resolution is substantial. At 1080p, Low delivers 60 FPS while High delivers 35 FPS, a 42% performance penalty for the higher visual quality. At 4K, the same settings comparison shows 46 FPS versus 27 FPS, a 41% penalty. This consistent percentage suggests that the GPU's fill rate and shading capacity are the limiting factors, rather than memory bandwidth or CPU overhead.

The Medium settings data provides the only complete min/max FPS information across all resolutions. At 1080p Medium, the average is 38 FPS with a minimum of 32 and maximum of 43. At 1440p Medium, the average drops to 34 FPS with a range of 29 to 39. At 4K Medium, the average is 29 FPS with a range of 24 to 33. The minimum FPS values are particularly telling; at 4K Medium, the minimum of 24 FPS indicates noticeable stuttering during intense scenes. The data shows that this combo is only viable for consistent gameplay at 1080p with Low settings, where the 60 FPS average provides a stable experience.

GPU Role

The AMD Radeon 880M is an integrated GPU based on the RDNA 3.5 architecture, manufactured on a 4 nm process by TSMC. It features 768 shading units, 48 texture mapping units, and 16 raster output units, along with 12 ray tracing cores. The GPU operates with a base clock of 400 MHz and a boost clock of 2900 MHz, which is a significant dynamic range. The memory configuration is "System Shared," meaning it relies on the host system's DDR5 memory for both capacity and bandwidth, with the memory bus width also being system-dependent.

In terms of raw compute, the 880M delivers 4.454 TFLOPS of FP32 performance and 4.454 TFLOPS of FP16 performance, indicating a 1:1 ratio. The pixel rate is 46.40 GPixel/s and the texture rate is 139.2 GTexel/s. These specifications place the GPU in the 43rd percentile of all GPUs, with an average benchmark score of 8436. The nearest rivals in the benchmark database are the NVIDIA GeForce GTX 675MX with a score of 8427 (0.1% delta), the NVIDIA GeForce MX330 with a score of 8458 (-0.3% delta), and the AMD Radeon HD 8870M with a score of 8462 (-0.3% delta). This places the 880M in the same performance tier as these older discrete mobile GPUs, which is notable for an integrated solution.

The GPU's benchmark results in DirectX tests show a score of 31 in Passmark DirectX 10, 73 in DirectX 11, 32 in DirectX 12, and 97 in DirectX 9. The 3DMark Steel Nomad DX12 score is 535. These results indicate that the GPU is more efficient in older API workloads, but the DirectX 12 performance is weak, which directly impacts Overpower's modern rendering requirements. The Passmark G3D score of 7615 and G2D score of 969 further illustrate that the GPU is better suited for 2D tasks than demanding 3D rendering. The GPU's TDP is 15 W, which is very low, and it uses no power connectors, confirming its integrated nature.

How This Combo Ranks

The combo of the Intel Core Ultra 7 155H and AMD Radeon 880M ranks 2907th out of 2980 tested combinations in Overpower. This places it in the bottom 2.5% of all tested systems, indicating that it is one of the weakest configurations for this game. This ranking is consistent with the measured FPS data, which shows that the combo struggles to maintain playable frame rates even at 1080p with higher settings.

The CPU itself is a strong performer in general benchmarks, with an average benchmark score of 32697 and a percentile ranking of 83rd among all CPUs. Its nearest rivals include the Intel Core i5-14600T with a score of 32707 (0% delta), the AMD Ryzen AI 7 PRO 360 with a score of 32662 (0.1% delta), the AMD Ryzen 5 7400F with a score of 32750 (-0.2% delta), and the AMD Ryzen 7 PRO 6850H with a score of 32812 (-0.4% delta). This shows that the CPU is competitive with mid-range desktop and mobile processors.

However, the GPU's ranking is much lower. The Radeon 880M sits in the 43rd percentile of all GPUs, and its nearest rivals include the NVIDIA GeForce GTX 675MX, which is a much older discrete GPU. In Overpower specifically, the GPU's limitations are the dominant factor in the low combo ranking. The data shows that even with a CPU that ranks in the 83rd percentile, the overall combo performance is dragged down by the integrated GPU. This highlights that for gaming, the GPU is the critical component, and a powerful CPU cannot compensate for a weak graphics processor.

CPU Role

The Intel Core Ultra 7 155H is a 16-core, 22-thread processor based on the Meteor Lake architecture, built on a 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 configuration includes 112 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3 cache. The CPU supports DDR5 memory with a dual-channel memory bus and a memory bandwidth of 89.6 GB/s. It uses the Intel BGA 2049 socket and has a PCIe Gen 5 interface with 8 lanes for the CPU.

In synthetic benchmarks, the 155H demonstrates strong multi-core performance. It scores 2450 in Cinebench R15 multi-core and 255 in single-core. In Cinebench R20, it scores 8754 multi-core and 1235 single-core. In Cinebench R23, it scores 15028 multi-core and 1743 single-core. The Passmark results show a multi-thread score of 24873 and a single-thread score of 3468. These scores place the CPU in the 83rd percentile of all CPUs, with an average benchmark score of 32697.

Despite this strong CPU performance, the Overpower results show that the CPU is not the limiting factor. The FPS data scales directly with resolution and settings, which is a characteristic of GPU-bound scenarios. For example, at 1080p Low, the system achieves 60 FPS, but at 1080p High, it drops to 35 FPS. If the CPU were the bottleneck, the frame rate would be more consistent across different settings at the same resolution. The CPU's 22 threads and high boost clock are more than sufficient for Overpower's gameplay, but the integrated GPU cannot keep up with the rendering demands. The CPU's memory bandwidth of 89.6 GB/s is also shared with the GPU, which could contribute to the performance limitations, but the primary constraint remains the GPU's compute and fill rate capabilities.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend on the user's priority for frame rate versus visual quality. The only configuration that provides a 60 FPS average is 1920x1080 with Low settings. This is the recommended choice for a smooth, responsive gaming experience. The Low settings at 1080p deliver a consistent 60 FPS, which is ideal for action games where frame timing is critical.

For users who want better visual fidelity, the 1440p Low setting provides a 54 FPS average, which is still playable but not as smooth as 60 FPS. The step up to 1440p Medium drops the average to 34 FPS, which is a significant 37% reduction from 1440p Low. This suggests that the cost of Medium settings at 1440p is too high for the visual benefit. At 1080p, the Medium setting achieves a 38 FPS average, which is a 37% drop from Low. The High setting at 1080p yields 35 FPS, and Ultra yields 29 FPS. These settings are all below the 60 FPS threshold and would result in a less fluid experience.

The 4K resolution results are not recommended for this combo. Even at Low settings, the average FPS is 46, which is below the 60 FPS target. At Medium settings, the average drops to 29 FPS with a minimum of 24 FPS, which will cause noticeable stuttering. The High and Ultra settings at 4K produce averages of 27 FPS and 22 FPS, respectively, which are not playable for an action game. The data clearly indicates that 1080p Low is the only viable configuration for a consistently smooth experience, with 1440p Low as an alternative for users who prefer higher resolution over absolute frame rate. All other settings combinations result in frame rates below 40 FPS, which is generally considered too low for a responsive action game.
