Overpower

The Intel Core Ultra 5 135H paired with the NVIDIA GeForce RTX 5090 Mobile delivers a robust 1080p and 1440p experience in Overpower, but the data reveals a clear shift in bottleneck behavior as resolution climbs. At 1080p, the system is heavily CPU-limited, evidenced by the dramatic FPS gains when lowering settings. The gap between Low and Ultra at 1920x1080 is 115 FPS (222 vs. 107), indicating that the GPU is not the primary constraint at this resolution. The scaling from High to Low at 1080p yields a 93 FPS increase, a 72% jump, which is far larger than what would be expected if the GPU were saturated. This suggests the Core Ultra 5 135H's 14 cores and 18 threads are sufficient to feed the RTX 5090 Mobile at lower settings, but the GPU is waiting on the CPU to deliver frames.

Moving to 2560x1440, the picture changes. The average FPS at Ultra drops to 95, while Low produces 198 FPS. The delta between Low and Ultra is 103 FPS, still substantial, but the relative scaling is tighter than at 1080p. The High preset at 1440p yields 115 FPS, which is only 14 FPS less than the 1080p High result of 129 FPS. This smaller drop indicates that the GPU is beginning to take on more of the workload, but the CPU still has headroom to push higher frame rates if settings are lowered. The 1440p Medium result of 124 FPS, with a minimum of 105 and maximum of 142, shows a stable frame time distribution that points to a balanced load between the two components.

At 3840x2160, the RTX 5090 Mobile becomes the clear limiting factor. The Ultra preset produces 81 FPS, while Low produces 168 FPS. The scaling from Low to Ultra is now a 87 FPS drop, but the absolute FPS values are high enough that the CPU is no longer the bottleneck. The 4K High result of 98 FPS is respectable, but the gap between 4K Low (168 FPS) and 4K Ultra (81 FPS) suggests that the GPU's 31.80 TFLOPS of FP32 compute is being taxed heavily by the higher resolution's pixel count. The data indicates that at 4K, the system is GPU-bound, and the Core Ultra 5 135H's performance is adequate to keep the GPU fed, but the graphics card's 896.0 GB/s memory bandwidth is what ultimately caps frame rates.

How This Combo Ranks

The combination of the Intel Core Ultra 5 135H and the NVIDIA GeForce RTX 5090 Mobile ranks 765th out of 3,713 tested combos in Overpower. This places it in the top 21% of all configurations, which is a strong showing for a mobile platform. The combo's percentile ranking is supported by the CPU's 81st percentile score against all CPUs and the GPU's 84th percentile score against all GPUs. However, the rank is not higher because the CPU is a mid-range mobile part, not a flagship. The Core Ultra 5 135H's average benchmark score of 29,093 is nearly identical to its nearest rivals, including the AMD Ryzen 7 5800X (29,123, delta -0.1%) and the Intel Core i5-13500HX (29,270, delta -0.6%). This indicates that the CPU is performing exactly as expected for its class, neither overachieving nor underperforming.

The GPU, on the other hand, is a top-tier mobile part. The RTX 5090 Mobile's average benchmark score of 45,152 is within 0.8% of the NVIDIA GeForce RTX 4070 Ti (44,795) and 1.8% below the NVIDIA RTX 5880 Ada Generation (45,972). This puts it in the same performance tier as desktop GPUs from the previous generation, which is why the combo ranks well. The rank of 765 is likely held back by the CPU's position in the hierarchy. In games that are more CPU-bound, this combo would rank lower, but in Overpower, which appears to scale well with GPU power, the RTX 5090 Mobile compensates for the CPU's mid-range status. The data shows that the combo is better suited for 1440p and 4K gaming, where the GPU's strengths are fully utilized, rather than 1080p, where the CPU's limitations become more apparent.

GPU Role

The NVIDIA GeForce RTX 5090 Mobile is the dominant component in this pairing, and its specifications explain the measured FPS results. The GPU features 24 GB of GDDR7 memory on a 256-bit bus, providing a bandwidth of 896.0 GB/s. This massive memory pool is more than sufficient for Overpower at any resolution, and the bandwidth ensures that texture streaming and high-resolution assets are not a bottleneck. The GPU's boost clock of 1515 MHz and base clock of 990 MHz are conservative for a 95 W TDP, but the Blackwell 2.0 architecture's efficiency allows it to deliver 31.80 TFLOPS of FP32 compute. This compute throughput is what drives the high frame rates at 1080p and 1440p, where the GPU is not fully saturated.

The GPU's 82 RT cores and 328 tensor cores are also relevant to Overpower's performance. While the game is an Action title, the presence of ray tracing hardware suggests that the engine can leverage these features, but the measured FPS data does not differentiate between rasterized and ray-traced scenarios. The 112 ROPs and 328 TMUs are responsible for pixel and texture processing, and their counts are high enough to handle the 4K resolution without dropping below playable frame rates. The 4K Ultra result of 81 FPS confirms the GPU's raw power, but it also shows that even this flagship mobile GPU cannot maintain 100+ FPS at the highest settings in 4K.

The GPU's benchmark scores further contextualize its role. The 3DMark Steel Nomad DX12 score of 5,871 and the Geekbench Vulkan score of 198,405 indicate strong DirectX 12 and Vulkan performance, which aligns with Overpower's modern engine requirements. The Passmark G3D score of 30,034 is slightly below the nearest rival, the AMD Radeon Pro 5500 XT (45,384, delta -0.5%), but this discrepancy is likely due to different test methodologies. The GPU's 84th percentile ranking against all GPUs confirms that it is a high-end part, and its performance in Overpower is consistent with that ranking. The data shows that the RTX 5090 Mobile is the primary driver of FPS in this combo, and its capabilities are well-matched to the 1440p and 4K resolutions where the CPU is less of a limiting factor.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend on the target resolution and desired frame rate. At 1920x1080, the Medium preset offers the best balance of performance and visual fidelity. The average FPS of 139 is high enough for smooth gameplay, and the minimum of 118 FPS ensures that frame drops are rare. The High preset at 1080p produces 129 FPS, which is also playable, but the 10 FPS gain from High to Medium is not worth the visual quality loss. The Ultra preset at 1080p drops to 107 FPS, which is still playable, but the jump from Medium to Ultra is a 32 FPS loss, making Medium the best choice for maintaining high frame rates without sacrificing too much detail.

At 2560x1440, the Medium preset again emerges as the sweet spot. The average FPS of 124, with a minimum of 105 and maximum of 142, provides a consistent experience that is suitable for fast-paced action. The High preset at 1440p yields 115 FPS, which is slightly lower but still acceptable for gamers who prefer higher visual quality. The Ultra preset at 1440p drops to 95 FPS, which is borderline for a 144Hz monitor. For 1440p, the recommendation is to use High if you have a 120Hz display, as the 115 FPS average will keep you near the refresh rate limit. If you prefer a higher frame rate, Medium is the better option, as the 124 FPS average gives you more headroom.

At 3840x2160, the GPU becomes the limiting factor, and the settings recommendations change accordingly. The High preset produces 98 FPS, which is ideal for 4K gaming on a 100Hz or 120Hz display. The Medium preset at 4K yields 105 FPS, which is a marginal improvement of 7 FPS over High, but the visual quality difference is noticeable. The Ultra preset at 4K drops to 81 FPS, which is playable but may not be smooth enough for competitive play. For 4K, the High preset is the recommended choice, as it offers the best combination of frame rate and visual fidelity. The Low preset at 4K produces 168 FPS, but the graphical compromises are too severe for most players. The data clearly shows that Medium is the best preset for 1080p and 1440p, while High is the best for 4K.

CPU Role

The Intel Core Ultra 5 135H is a 14-core, 18-thread mobile processor based on the Meteor Lake architecture, built on Intel's 7 nm process. Its base clock of 3.60 GHz and boost clock of 4.60 GHz are modest for a mobile part, but the CPU's 18 MB of shared L3 cache and 2 MB per core L2 cache help mitigate latency in gaming workloads. The CPU's benchmark scores reveal its position in the hierarchy: the Cinebench R23 multi-core score of 11,875.5 and single-core score of 1,700 indicate that it is a competent performer, but not a top-tier part. The Passmark single-thread score of 3,521 and multi-thread score of 22,422 further confirm this, placing the CPU at the 81st percentile against all CPUs.

In Overpower, the CPU's role is to feed the GPU with draw calls and game logic. At 1080p, the CPU becomes the bottleneck, as the GPU is powerful enough to render frames faster than the CPU can issue them. This is evident from the 222 FPS average at Low settings, which is a 93 FPS increase over High settings. The CPU's 14 cores and 18 threads are more than enough for the game's multi-threaded workload, but the single-thread performance, as measured by the Passmark single-thread score of 3,521, limits the maximum frame rate at lower resolutions. The CPU's nearest rival, the Intel Core i5-13500HX, has an average score of 29,270, which is 0.6% higher, indicating that the 135H is slightly behind in raw compute.

At 1440p and 4K, the CPU's limitations are less pronounced. The GPU's workload increases with resolution, giving the CPU more time to prepare frames. The 1440p Medium result of 124 FPS and the 4K Medium result of 105 FPS show that the CPU can keep up with the RTX 5090 Mobile's rendering pace at higher resolutions. The CPU's memory bandwidth of 89.6 GB/s, while lower than the GPU's 896.0 GB/s, is sufficient for the game's system memory requirements. The CPU's TDP of 28 W is low for a mobile part, which means it can sustain its boost clock for longer periods without thermal throttling, as evidenced by the stable FPS numbers across all settings.

The data indicates that the Core Ultra 5 135H is a solid match for the RTX 5090 Mobile in Overpower, but it is not without compromise. At 1080p, the CPU holds back the GPU's potential, capping frame rates at 222 FPS on Low and 129 FPS on High. However, for most gamers playing at 1440p or 4K, the CPU's performance is more than adequate, and the combo delivers playable frame rates at all settings. The CPU's 81st percentile ranking and its benchmark scores, such as the Cinebench R23 multi-core score of 11,875.5, show that it is a capable mid-range processor that can handle modern games without becoming a significant bottleneck at higher resolutions.
