Overpower

Settings Recommendations

The measured FPS rows for Overpower show a clear hierarchy across the four available presets, with the gap between Low and Ultra widening as resolution increases. At 1920x1080, the Low preset delivers 213 FPS average, while High drops to 123 FPS and Ultra falls to 102 FPS. Medium sits at 133 FPS. The most balanced experience, however, comes from the Medium preset, which provides a 133 FPS average at 1080p with a minimum of 113 FPS and a maximum of 153 FPS. That consistency matters: the min-to-max spread of 40 FPS is tighter than the implied spread at other presets where only averages are reported.

Moving to 2560x1440, Medium again proves to be the sweet spot. It averages 118 FPS with a minimum of 101 FPS and a maximum of 136 FPS. High trails at 110 FPS, Ultra drops to 91 FPS, and Low jumps to 190 FPS. The Low preset, while numerically fastest, sacrifices visual fidelity for headroom that most displays at this resolution cannot fully exploit unless they support very high refresh rates. For a 144Hz panel, Medium's 118 FPS average is comfortably above the refresh threshold, while the 101 FPS minimum ensures no prolonged dips below it.

At 3840x2160, the picture changes. Medium averages 101 FPS with a minimum of 86 FPS and a maximum of 116 FPS. High comes in at 93 FPS, Ultra at 78 FPS, and Low at 161 FPS. Here, Medium is the only preset that keeps the average above the 100 FPS mark while maintaining a minimum above 85 FPS. Ultra, at 78 FPS, is playable but visibly less smooth, and the 86 FPS minimum at Medium provides a safer buffer against sudden frame-time spikes. Benchmark results indicate that Medium offers the best combination of frame rate stability and visual quality across all three resolutions, making it the recommended preset for this combo.

How This Combo Ranks

The combination of the Intel Core Ultra 7 155H and the NVIDIA GeForce RTX 4090 Mobile ranks 815th out of 3713 tested combos in Overpower. That places it in the top 22% of all configurations tested, a solid showing for a mobile platform. The percentile data for the individual components reinforces this: the CPU sits at the 83rd percentile against all CPUs, and the GPU sits at the 84th percentile against all GPUs. Both components are above average, and the combo rank reflects that synergy.

What is notable is how close the CPU is to its nearest rivals in synthetic benchmarks. The Intel Core Ultra 7 155H has an average benchmark score of 32697, while the Intel Core i5-14600T scores 32707 (a delta of 0%), the AMD Ryzen AI 7 PRO 360 scores 32662 (0.1% higher), the AMD Ryzen 5 7400F scores 32750 (0.2% lower), and the AMD Ryzen 7 PRO 6850H scores 32812 (0.4% lower). These deltas are all within a fraction of a percent, meaning the CPU is essentially tied with those rivals in raw compute. For Overpower, this indicates that the CPU is unlikely to be a differentiating factor among systems in this class.

The GPU tells a similar story. The RTX 4090 Mobile has an average benchmark score of 43667, with the NVIDIA Quadro M6000 at 43301 (0.8% lower), the RTX 5050 Mobile at 43268 (0.9% lower), the Quadro M6000 24 GB at 43262 (0.9% lower), and the RTX A6000 at 44075 (0.9% higher). Again, the deltas are minimal, suggesting that in Overpower, the GPU performance is tightly clustered with these competitors. The combo rank of 815 out of 3713, therefore, is not driven by any single component being exceptional but by both being consistently above average. The data shows that this combo is competitive with a broad swath of the tested field, though it does not break into the top tier.

GPU Role

The NVIDIA GeForce RTX 4090 Mobile is built on the Ada Lovelace architecture with a 5 nm process from TSMC. It packs 9728 shading units, 304 texture mapping units, and 112 raster output units. The chip, designated AD103, contains 45,900 million transistors on a 379 mm² die, giving a transistor density of 121.1 million per square millimeter. The memory subsystem is substantial: 16 GB of GDDR6 on a 256-bit bus, yielding a bandwidth of 576.0 GB/s. The memory clock runs at 2250 MHz, which translates to 18 Gbps effective.

The clock behavior is worth examining. The base clock is 1335 MHz, and the boost clock is 1695 MHz. That is a modest boost ratio of roughly 27%, and in a game like Overpower, this means the GPU will spend most of its time near the boost ceiling under sustained load. The pixel rate is 189.8 GPixel/s, and the texture rate is 515.3 GTexel/s. Floating-point performance is rated at 32.98 TFLOPS for both FP32 and FP16, indicating a 1:1 ratio. The 76 RT cores and 304 tensor cores provide hardware support for ray tracing and DLSS, though the measured FPS data does not specify whether these features are enabled.

The TDP is 120 W, which for a mobile GPU is relatively high, but the slot width is listed as "IGP," meaning this is integrated into the system board rather than a discrete MXM module. The bus interface is PCIe 4.0 x16, which provides ample bandwidth for the 16 GB frame buffer. In Overpower, the 16 GB VRAM capacity is more than sufficient for the highest preset at any resolution, and the bandwidth of 576.0 GB/s ensures that texture streaming and geometry processing do not become bottlenecks. Benchmark results indicate that the GPU's role in this combo is to provide headroom at 4K, where the Medium preset still yields 101 FPS, and to dominate at lower resolutions where the frame rates exceed 200 FPS.

Measured FPS Breakdown

At 1920x1080, the measured FPS values show a clear gradient. Low settings produce an average of 213 FPS, Medium produces 133 FPS with a minimum of 113 FPS and a maximum of 153 FPS, High produces 123 FPS, and Ultra produces 102 FPS. The step from Low to Medium is a drop of 80 FPS, which is substantial, but the step from Medium to High is only 10 FPS, and from High to Ultra is 21 FPS. This suggests that Medium is the point of diminishing returns for visual quality versus frame rate at this resolution.

At 2560x1440, the same pattern holds but with lower absolute numbers. Low averages 190 FPS, Medium averages 118 FPS (min 101, max 136), High averages 110 FPS, and Ultra averages 91 FPS. The drop from Low to Medium is 72 FPS, from Medium to High is 8 FPS, and from High to Ultra is 19 FPS. The minimum at Medium is still above 100 FPS, which is a strong result for a 1440p panel.

At 3840x2160, the numbers compress further. Low averages 161 FPS, Medium averages 101 FPS (min 86, max 116), High averages 93 FPS, and Ultra averages 78 FPS. The drop from Low to Medium is 60 FPS, from Medium to High is 8 FPS, and from High to Ultra is 15 FPS. Notably, the Medium preset at 4K has a minimum of 86 FPS, which is only 15 FPS below the High average at the same resolution. This indicates that the Medium preset provides a more stable experience at 4K than the preset name might suggest.

Resolution Scaling

The FPS drop from 1080p to 4K varies by preset, and that variance reveals the limiting component. At Low settings, the average FPS drops from 213 at 1080p to 190 at 1440p (a 10.8% decrease) and then to 161 at 4K (a 15.3% decrease from 1440p). The total drop from 1080p to 4K is 24.4%. At Medium settings, the drop is from 133 to 118 (11.3%) and then to 101 (14.4%), a total drop of 24.1%. At High settings, the drop is from 123 to 110 (10.6%) and then to 93 (15.5%), a total drop of 24.4%. At Ultra settings, the drop is from 102 to 91 (10.8%) and then to 78 (14.3%), a total drop of 23.5%.

These percentages are remarkably consistent across presets. The total drop from 1080p to 4K hovers around 24% regardless of whether the game is running at Low or Ultra. This consistency is a strong indicator that the GPU is the primary limiting factor at all resolutions and settings. If the CPU were the bottleneck, the drop from 1080p to 4K would be smaller at higher settings, because the CPU load would remain constant while the GPU load increased. Instead, the uniform scaling suggests that the RTX 4090 Mobile is doing the heavy lifting, and the frame rate scales predictably with the number of pixels rendered.

The 1440p to 4K drop is slightly steeper than the 1080p to 1440p drop for every preset, which is expected given that 4K has 2.25 times the pixels of 1440p, versus 1.78 times for 1440p over 1080p. The data shows that this combo is GPU-limited across the board, and the CPU has sufficient headroom to keep feeding the GPU even at Low settings where frame rates exceed 200 FPS.

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. The base clock is 3.80 GHz, and the boost clock reaches 4.80 GHz. The cache hierarchy includes 112 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3 cache. Memory support is DDR5 with a dual-channel bus, providing a bandwidth of 89.6 GB/s. The CPU is not multiplier-unlocked, so overclocking is not an option, and it uses the Intel BGA 2049 socket.

In synthetic benchmarks, the CPU scores 15028 in Cinebench R23 multi-core and 1743 in single-core. PassMark results show a multi-thread score of 24873 and a single-thread score of 3468. These numbers place the CPU at the 83rd percentile against all CPUs. In Overpower, the CPU's role is to ensure that the GPU is never starved of data. The 22 threads are more than sufficient for the game's threading model, and the 4.80 GHz boost clock provides strong single-thread performance for game logic and physics.

The fact that the FPS scaling from 1080p to 4K is consistent across all presets, as noted in the Resolution Scaling section, indicates that the CPU is not a bottleneck at any resolution. Even at Low settings with 213 FPS at 1080p, the CPU keeps pace. The 24 MB of L3 cache and the dual-channel DDR5 bandwidth are adequate for feeding the GPU's 16 GB frame buffer. The nearest rivals in CPU benchmarks all score within 0.4% of the Ultra 7 155H, so in a game like Overpower, swapping this CPU for any of those would yield negligible differences in frame rates. The CPU is a capable partner for the RTX 4090 Mobile, providing the necessary compute headroom without becoming the limiting factor.
