Overpower

The Overpower benchmark results for the Intel Core Ultra 7 155H paired with the NVIDIA GeForce RTX 5090 Mobile present a clear picture of a system where the GPU is the dominant performance driver. The data shows a consistent scaling pattern across resolutions, with the frame rate dropping by roughly 22% to 27% when moving from 1440p to 4K at identical settings. Specifically, at High settings, the average FPS falls from 115 at 2560x1440 to 98 at 3840x2160, a reduction of 17 FPS. At Low settings, the drop is more severe, from 198 down to 168 FPS, indicating that the lower graphical load allows the CPU to push harder but still cannot overcome the pixel fill rate demands of 4K. This scaling behavior suggests that at 1080p, the system is likely hitting a performance ceiling where the CPU and GPU are more balanced, as the jump from 1080p to 1440p at High settings only costs 14 FPS (129 to 115), whereas the jump from 1440p to 4K costs 17 FPS. The pattern is consistent for all presets, confirming that the RTX 5090 Mobile’s 24 GB of GDDR7 memory and 896.0 GB/s bandwidth are sufficient for 4K, but the rendering load at that resolution still imposes a significant tax on the frame rate.

Resolution Scaling

The measured FPS data reveals a predictable yet informative resolution scaling curve. At 1920x1080 with Low settings, the combo achieves an average of 222 FPS, which is exceptionally high and suggests the CPU, with its 16 cores and 22 threads boosting to 4.80 GHz, is not the limiting factor at this resolution. The frame rate drops to 198 FPS at 1440p Low, a decrease of 24 FPS or roughly 10.8%, which is a modest penalty for the increased pixel count. Moving to 4K Low, the average falls to 168 FPS, a further 30 FPS drop (15.2%) from 1440p. This steeper decline at 4K indicates the GPU’s shading units (10,496) and texture mapping units (328) are being saturated, despite the massive memory bandwidth.

At higher quality settings, the scaling becomes more linear. For Medium settings, the averages are 139 FPS at 1080p, 124 FPS at 1440p, and 105 FPS at 4K. The percentage drops are 10.8% from 1080p to 1440p, and then 15.3% from 1440p to 4K. This suggests that as the visual complexity increases, the GPU’s compute resources become more critical, and the relative cost of each additional pixel grows. High settings show a similar trend: 129 FPS at 1080p, 115 FPS at 1440p (down 10.9%), and 98 FPS at 4K (down 14.8%). The Ultra preset, which is the most demanding, yields 107 FPS at 1080p, 95 FPS at 1440p, and 81 FPS at 4K, with the 1440p to 4K drop being 14.7%.

These numbers indicate that the limiting component shifts with resolution. At 1080p, the CPU’s performance, which places it in the 83rd percentile of all CPUs and roughly on par with the Intel Core i5-14600T, is more relevant, as the RTX 5090 Mobile can easily outpace the processor’s ability to feed it frames. The data supports this by showing a 73 FPS difference between Low and Ultra at 1080p (222 vs 107), which narrows to an 87 FPS difference at 4K (168 vs 81). The wider gap at 4K confirms that the GPU is the primary bottleneck at higher resolutions, while the smaller gap at 1080p suggests the CPU limits the maximum achievable frame rate. For players targeting high refresh rate 1080p monitors, this combo is capable of exceeding 200 FPS on Low, but those seeking 4K gaming will need to accept frame rates in the 80-100 FPS range on Ultra, which is still very playable.

GPU Role

The NVIDIA GeForce RTX 5090 Mobile is the undoubted star of this configuration, and its specifications explain the high frame rates observed. The GPU features 24 GB of GDDR7 memory on a 256-bit bus, providing a bandwidth of 896.0 GB/s. This substantial memory allocation ensures that even at 4K with Ultra textures, the frame buffer is unlikely to be exhausted, which is critical for maintaining smooth performance in a modern action game like Overpower. The memory clock runs at 1750 MHz, translating to 28 Gbps effective, which is a high-speed implementation that complements the 10496 shading units.

The GPU’s base clock is 990 MHz, with a boost clock of 1515 MHz. These clocks are relatively modest for a flagship mobile GPU, but the architecture’s efficiency compensates. The FP32 performance is rated at 31.80 TFLOPS, which is a strong number that directly correlates with the observed 4K performance. For instance, at 4K Medium, the combo produces 105 FPS, which is a demanding workload that requires immense pixel throughput. The pixel rate of 169.7 GPixel/s and texture rate of 496.9 GTexel/s are the key metrics for this game’s visual effects, which likely include high-resolution textures and complex shaders.

The GPU’s TDP is listed at 95 W, which is relatively low for a product with this level of performance, indicating a highly efficient design that can sustain high clocks without excessive power draw. This is reflected in the benchmark scores, where the GPU sits in the 84th percentile of all GPUs. Its nearest rival, the AMD Radeon Pro 5500 XT, has a slightly higher average score of 45,384, but the RTX 5090 Mobile is 0.5% behind, while it is 0.8% ahead of the RTX 4070 Ti. In Overpower specifically, the data shows that the GPU is the bottleneck at 4K, as evidenced by the significant frame rate drops when increasing from 1440p to 4K. The CPU’s 24 MB of shared L3 cache and dual-channel memory bandwidth of 89.6 GB/s are sufficient to feed the GPU, but they do not contribute to the frame rate scaling at higher resolutions.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across three resolutions and four quality presets. At 1920x1080, the Low preset yields an average of 222 FPS, which is the highest recorded in the dataset. The Medium preset averages 139 FPS, with a minimum of 118 and a maximum of 160 FPS, showing a tight range that suggests stable performance. The High preset averages 129 FPS, and the Ultra preset averages 107 FPS. This 1080p data indicates that the system is capable of driving high refresh rate displays, with even Ultra settings exceeding 100 FPS.

Moving to 2560x1440, the performance remains impressive. The Low preset averages 198 FPS, a 24 FPS drop from 1080p. The Medium preset averages 124 FPS (min 105, max 142), which is a 15 FPS reduction from 1080p. The High preset averages 115 FPS, and the Ultra preset averages 95 FPS. These numbers suggest that 1440p is the sweet spot for this combo, as even Ultra settings stay above 90 FPS, which is ideal for high-refresh-rate 1440p monitors. The minimum FPS of 105 at Medium settings indicates that the system rarely dips below 100 FPS, providing a smooth experience.

At 3840x2160, the performance is still very playable, but the frame rates drop to a range where high refresh rates are less achievable. The Low preset averages 168 FPS, which is still exceptionally high for 4K. The Medium preset averages 105 FPS (min 90, max 121), showing that the minimum can dip to 90 FPS, which is still above the 60 FPS threshold for smooth gameplay. The High preset averages 98 FPS, and the Ultra preset averages 81 FPS. The 4K data demonstrates that the RTX 5090 Mobile is a capable 4K GPU, but users should expect to use Medium or High settings to maintain frame rates above 100 FPS. The gap between Low and Ultra at 4K is 87 FPS, which is the largest of any resolution, underscoring the GPU’s sensitivity to settings at this pixel density.

How This Combo Ranks

The combination of the Intel Core Ultra 7 155H and the NVIDIA GeForce RTX 5090 Mobile achieves a rank of 765 out of 3,713 tested combos in Overpower.

The CPU’s average benchmark score of 32,697 and the GPU’s score of 45,152 are both strong, but the GPU’s 84th percentile ranking is slightly higher than the CPU’s 83rd percentile. This suggests that the GPU is the more capable component relative to its peers.

When compared to other combos, this pairing benefits from the GPU’s high memory bandwidth and the CPU’s multi-threading capabilities. The CPU’s 16 cores and 22 threads are well-suited for modern game engines that can utilize multiple threads for physics and AI, which is likely a factor in Overpower’s action genre. The combo’s rank of 765 means that there are 764 other configurations that deliver higher average frame rates in this game, but many of those likely feature more powerful desktop CPUs or higher-tier mobile GPUs. The data shows that this laptop combo is solidly in the upper echelon of gaming performance, and the 4K results, with an average of 81 FPS on Ultra, are particularly notable for a mobile platform.

The nearest CPU rivals, such as the Intel Core i5-14600T and AMD Ryzen 7 PRO 6850H, have nearly identical average scores, but the RTX 5090 Mobile’s dominance over the GPU rivals (like the RTX 4070 Ti) ensures that this combo remains competitive. The rank is a holistic measure, and the data indicates that the bottleneck is more often the CPU at 1080p, where the frame rates approach 220 FPS, but the GPU becomes the limiting factor at 4K. This balanced behavior is a hallmark of a well-matched system, even if it does not top the charts.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend on the user’s display resolution and refresh rate. For 1080p displays, the Ultra preset is recommended, as it delivers an average of 107 FPS, which is well above the 60 FPS threshold and smooth enough for most gaming monitors. The High preset at 129 FPS is also excellent, but the visual fidelity gain from Ultra is worth the 22 FPS cost for users with 144Hz or 165Hz displays who want the best image quality. The Low preset at 222 FPS is unnecessary for most users, as it will likely exceed the refresh rate of any 1080p monitor, but it is available for competitive players who prioritize maximum frame pacing.

For 1440p displays, the High preset is the best balance of performance and quality, with an average of 115 FPS. This is ideal for 144Hz monitors, as it provides a high frame rate with minimal visual compromises. The Medium preset at 124 FPS is also viable, and the Ultra preset at 95 FPS is acceptable for users who prefer maximum visual settings over a higher refresh rate. The data shows that the system can handle 1440p Ultra at nearly 100 FPS, making it a strong choice for high-end gaming laptops.

For 4K displays, the Medium preset is the recommended starting point, with an average of 105 FPS and a minimum of 90 FPS. This ensures that the frame rate rarely drops below 90 FPS, providing a consistently smooth experience. The High preset at 98 FPS is also viable, but the Medium preset offers a slightly higher floor. The Ultra preset at 81 FPS is playable, but the 24 FPS drop from Medium to Ultra may be noticeable in fast-paced action scenes. The Low preset at 168 FPS is overkill for most 4K monitors, which typically have a 60Hz or 120Hz refresh rate. Ultimately, the data suggests that users should prioritize Medium or High settings for 4K to maintain frame rates above 100 FPS, while 1440p users can comfortably use High or Ultra, and 1080p users can max out the game without hesitation.
