# CPU Role

The Intel Core Ultra 7 155H is a Meteor Lake architecture processor built on Intel's 7 nm process node. It features 16 cores and 22 threads, with a base clock of 3.80 GHz and a boost clock of 4.80 GHz. The thermal design power is 28 W, which is modest for a processor with this core count, but the architecture's efficiency helps maintain competitive performance. The CPU's cache hierarchy includes 112 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3 cache, providing a solid foundation for gaming workloads.

In Overpower, the CPU's role is significant at 1080p, where the game's action-oriented mechanics demand consistent frame pacing. The 22 threads support the game's multi-threaded rendering and physics calculations, while the boost clock of 4.80 GHz ensures single-threaded responsiveness for gameplay logic. The Cinebench R23 multi-core score of 15,028 and single-core score of 1,743 indicate balanced performance that prevents the CPU from becoming a dominant bottleneck at higher resolutions.

The CPU sits at the 83rd percentile among all processors in the database, with an average benchmark score of 32,697. Its nearest rival, the Intel Core i5-14600T, scores 32,707, a delta of 0%, meaning the two are statistically identical in overall CPU performance. The AMD Ryzen AI 7 PRO 360 is 0.1% ahead, while the AMD Ryzen 5 7400F is 0.2% behind, and the AMD Ryzen 7 PRO 6850H trails by 0.4%. These narrow margins suggest the 155H is well-positioned among mid-range to upper-mid-range processors, though it is not a top-tier performer.

The 16 cores and 22 threads are particularly relevant for Overpower's background simulation and AI behavior. The game's action sequences can spawn numerous entities, and the CPU's thread count ensures these processes don't starve the main game loop. The 24 MB of L3 cache also helps reduce memory latency during rapid scene transitions, which is critical for maintaining smooth gameplay during combat.

# Resolution Scaling

The measured FPS data reveals a clear pattern of scaling from 1080p to 4K, with the RTX 5090 becoming increasingly dominant as resolution rises. At Low settings, the frame rate drops from 222 FPS at 1080p to 198 FPS at 1440p, a reduction of approximately 11%, and then to 168 FPS at 4K, another 15% drop. This scaling indicates that at lower resolutions, the CPU is the limiting factor, as the GPU has ample headroom to render frames faster than the CPU can feed it.

At High settings, the scaling is more pronounced: 129 FPS at 1080p drops to 115 FPS at 1440p (an 11% decrease) and then to 98 FPS at 4K (a 15% decrease). The consistent percentage drops across resolutions suggest that the game's rendering load scales predictably, and the GPU is becoming more influential as resolution increases. The RTX 5090's 32 GB of VRAM and 1.79 TB/s bandwidth ensure that memory capacity is never a constraint, even at 4K with high-detail textures.

The Medium settings show a similar trend, with 139 FPS at 1080p falling to 124 FPS at 1440p and 105 FPS at 4K. Ultra settings produce the lowest frame rates but the most consistent scaling: 107 FPS at 1080p, 95 FPS at 1440p, and 81 FPS at 4K. The 24% drop from 1080p to 4K at Ultra settings is the smallest relative decrease among all presets, indicating that at maximum settings, the GPU is the primary bottleneck across all resolutions.

The data suggests that at 1080p, the Core Ultra 7 155H limits performance, particularly at Low and Medium settings where frame rates exceed 200 FPS. The CPU's 28 W TDP and mobile design cannot sustain frame rates beyond that threshold, even with the RTX 5090's enormous compute capability. At 4K, however, the GPU's 104.8 TFLOPS of FP32 performance and 423.6 GPixel/s pixel rate become the determining factor, and the CPU's influence diminishes significantly.

# Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates across all settings. Low settings produce an average of 222 FPS, which is exceptionally high and indicates that the CPU is the limiting factor—the RTX 5090 could likely push far beyond this if not for the 155H's constraints. Medium settings yield 139 FPS average, with a minimum of 118 FPS and a maximum of 160 FPS, providing a smooth experience with minor frame dips. High settings reduce the average to 129 FPS, while Ultra settings bring it down to 107 FPS. The spread from Low to Ultra at 1080p is 115 FPS, demonstrating significant headroom for players who prioritize frame rate over visual fidelity.

At 2560x1440, the frame rates remain high but show a more balanced CPU-GPU interaction. Low settings average 198 FPS, a 24 FPS drop from 1080p, indicating that the GPU is starting to take on more load. Medium settings average 124 FPS, with a minimum of 105 FPS and a maximum of 142 FPS, offering a stable experience for high-refresh-rate monitors. High settings produce 115 FPS average, and Ultra settings drop to 95 FPS. The 103 FPS difference between Low and Ultra at 1440p is slightly smaller than at 1080p, reflecting the increased GPU workload.

At 3840x2160, the RTX 5090's dominance becomes evident. Low settings average 168 FPS, which is still exceptionally high for 4K gaming, and represents only a 54 FPS drop from 1080p. Medium settings average 105 FPS, with a minimum of 90 FPS and a maximum of 121 FPS, providing a solid 4K experience with some headroom. High settings produce 98 FPS average, and Ultra settings drop to 81 FPS. The 87 FPS difference between Low and Ultra at 4K is the smallest among all resolutions, confirming that the GPU is the primary driver of performance at this resolution.

The data shows that the Medium preset offers the most balanced experience across all resolutions, with frame rates ranging from 105 FPS at 4K to 139 FPS at 1080p. The minimum FPS values for Medium settings (90 FPS at 4K, 105 FPS at 1440p, 118 FPS at 1080p) indicate that frame pacing remains consistent, with no severe dips that would cause stuttering. The maximum values (121 FPS at 4K, 142 FPS at 1440p, 160 FPS at 1080p) show that the combo has headroom to burst above average when scenes are less demanding.

# GPU Role

The NVIDIA GeForce RTX 5090 is the dominant component in this combo, built on the Blackwell 2.0 architecture with a 5 nm process node from TSMC. The chip contains 92,200 million transistors on a 750 mm² die, with a transistor density of 122.9 million per mm². The GPU's base clock is 2017 MHz, boosting to 2407 MHz, and its memory runs at 1750 MHz with an effective speed of 28 Gbps. The 32 GB of GDDR7 memory on a 512-bit bus provides 1.79 TB/s of bandwidth, ensuring that even the most demanding textures and effects in Overpower are handled without memory bottlenecks.

The RTX 5090's compute capabilities are staggering: 21,760 shading units, 680 texture mapping units, and 176 raster output units. The 170 RT cores and 680 tensor cores provide dedicated hardware for ray tracing and AI-enhanced features, though Overpower's action genre may not heavily utilize these. The pixel rate of 423.6 GPixel/s and texture rate of 1,636.8 GTexel/s ensure that the GPU can fill frames at extremely high resolutions, as evidenced by the 4K performance data.

The GPU achieves a 92nd percentile ranking among all GPUs, with an average benchmark score of 79,842. Its nearest rival, the NVIDIA Tesla P100 PCIe 16 GB, scores 79,605, a delta of 0.3%, while the Tesla P100 PCIe 12 GB is 0.6% behind, and the AMD Radeon RX 6850M XT trails by 1.1%. The AMD Radeon Pro Vega 64X is 1.4% ahead, which is a narrow margin given the RTX 5090's specifications. This ranking confirms that the GPU is a top-tier performer, though the comparison to older Tesla cards and mobile Radeon parts suggests the benchmark database's average scores do not fully capture the RTX 5090's gaming-specific strengths.

In Overpower, the GPU's role is most critical at 4K resolution, where the 4K Low settings achieve 168 FPS and 4K Ultra reaches 81 FPS. The 32 GB VRAM capacity is far beyond what Overpower requires, but it ensures that future updates or mods with higher-resolution textures will not cause memory overflow. The 1.79 TB/s bandwidth allows the GPU to stream textures at high speed, reducing load times and preventing pop-in during fast-paced action sequences.

The RTX 5090's 104.8 TFLOPS of FP32 performance translates directly to raw rendering power, enabling the high frame rates observed even at 4K Ultra settings. The 176 ROPs ensure efficient pixel output, which is critical for maintaining the 81 FPS average at 4K Ultra. The GPU's dual-slot design and 575 W TDP indicate that it requires substantial cooling and power, but the benchmark data shows that this power is effectively converted into performance.

# Settings Recommendations

Based on the measured FPS data, the Medium preset offers the best balance between visual quality and performance across all resolutions. At 1080p, Medium delivers 139 FPS average with a minimum of 118 FPS, which is well above the threshold for smooth gameplay on high-refresh-rate displays. At 1440p, Medium produces 124 FPS average with a 105 FPS minimum, providing a comfortable margin above the 60 FPS standard. At 4K, Medium achieves 105 FPS average with a 90 FPS minimum, which is impressive for the resolution and ensures that even demanding scenes stay above playable frame rates.

For players with 1080p monitors seeking maximum frame rates, Low settings are the clear choice, delivering 222 FPS average. This is likely far beyond the refresh rate of most monitors, but it provides headroom for competitive play where every frame counts. The 222 FPS at 1080p Low also confirms that the CPU is the bottleneck at this setting, as the RTX 5090 could theoretically push higher if the 155H could keep up.

Ultra settings are viable for players who prioritize visual fidelity over frame rate, but the data shows significant trade-offs. At 1080p Ultra, the average drops to 107 FPS, which is still playable but a 115 FPS reduction from Low. At 4K Ultra, the 81 FPS average is acceptable for a visually rich experience, but players with 120 Hz or higher refresh monitors will notice the difference compared to Medium settings. The minimum FPS values are not provided for Ultra settings, which makes it difficult to assess frame pacing, but the averages suggest consistent performance.

High settings offer a middle ground, with 129 FPS at 1080p, 115 FPS at 1440p, and 98 FPS at 4K. This preset is recommended for players who want improved visuals over Medium without the performance penalty of Ultra. However, the data shows that Medium is more consistent, with documented minimum and maximum values that indicate stable frame delivery. For most players, Medium is the optimal choice, as it provides the best combination of visual quality and performance headroom.
