Minimum

The pairing of the Intel Core Ultra 5 135H with the NVIDIA GeForce RTX 5090 presents a stark contrast in capabilities, pitting a mobile-focused processor against a flagship desktop graphics card. The benchmark data from Minimum reveals a system that is heavily constrained by its CPU in many scenarios, yet still capable of delivering high frame rates at lower resolutions. This analysis breaks down how the components interact across settings and resolutions, what the numbers indicate about system balance, and where the optimal experience lies.

Resolution Scaling

The frame rate data shows a classic pattern of GPU load increasing with resolution, but the degree of change reveals the bottleneck dynamics. At 1080p with Low settings, the system produces an average of 293 FPS. Moving to 1440p Low drops this to 189 FPS, a reduction of 104 FPS. At 4K Low, the average falls further to 102 FPS. This scaling from 1080p to 4K at Low settings represents a 65% decrease in average frame rate, indicating that while the GPU is becoming more stressed, the CPU is still able to feed it enough data to maintain high output. The 1080p Low result of 293 FPS is exceptionally high, suggesting the game engine is not fully taxing the RTX 5090 at this setting.

With High settings, the scaling story changes. At 1080p High, the average is 188 FPS. At 1440p High, it drops to 121 FPS, and at 4K High, it reaches 65 FPS. The transition from 1080p to 1440p High is a 67 FPS drop, while the jump to 4K High is another 56 FPS loss. This steeper decline compared to Low settings shows that the increased graphical workload is beginning to engage the GPU more substantially, though the 1080p High result of 188 FPS is still far below the 293 FPS seen at Low, suggesting that even at High settings, the CPU might be limiting peak performance at 1080p.

The Ultra preset provides the clearest view of GPU scaling. At 1080p Ultra, the average is 143 FPS. At 1440p Ultra, it drops to 92 FPS, and at 4K Ultra, it falls to 50 FPS. The 4K Ultra result of 50 FPS is the lowest recorded average in the dataset, and the step from 1440p to 4K is a 42 FPS reduction. This pattern indicates that at Ultra settings, the RTX 5090 is finally being pushed hard enough that resolution becomes the dominant factor. The data suggests that the system is CPU-limited at lower resolutions and settings, with the GPU only becoming the primary constraint at 4K with higher quality presets.

GPU Role

The NVIDIA GeForce RTX 5090 is a flagship part with 32 GB of GDDR7 memory on a 512-bit bus, providing a bandwidth of 1.79 TB/s. Its boost clock is rated at 2407 MHz. These specifications are enormously powerful, and the benchmark results show that the GPU has significant headroom in this game. The 3DMark Steel Nomad DX12 score of 18355 and a Passmark G3D score of 39650 place it in the 92nd percentile of all GPUs, confirming its high-end positioning.

Despite this hardware power, the measured FPS in Minimum shows that the GPU is often not the limiting factor. The fact that 1080p Low yields 293 FPS while 4K Ultra yields 50 FPS demonstrates the GPU's scaling capability, but the relatively modest gains from Low to Ultra at the same resolution point to other constraints. For instance, at 1080p, moving from Low to Ultra reduces the average from 293 to 143 FPS, which is a 51% drop. This is a larger performance hit than typical for a purely GPU-bound scenario, suggesting that the CPU cannot maintain the data flow required for the higher settings at that resolution.

The GPU's memory subsystem is a key asset. With 32 GB of VRAM, capacity is not a concern at any tested setting. The bandwidth of 1.79 TB/s ensures that texture streaming and geometry data can be fed to the shader units without stuttering. The data shows a minimum FPS of 66 at 4K Medium, which is the only recorded minimum in the dataset besides the 1440p Medium and 1080p Medium values. This suggests that while average frame rates are high, there can be dips, but the large VRAM buffer likely prevents severe hitches. The RTX 5090's performance is clearly sufficient to drive high frame rates; the question is whether the rest of the system can keep up.

CPU Role

The Intel Core Ultra 5 135H is a mobile processor with 14 cores and 18 threads, based on the Meteor Lake architecture. It has a base clock of 3.60 GHz and a boost clock of 4.60 GHz, with 18 MB of shared L3 cache. Its TDP is 28 W, which is a clear indicator of its efficiency-focused design. In synthetic benchmarks, it achieves a Cinebench R23 multi-core score of 11875.5 and a single-core score of 1700. Its average benchmark score of 29093 places it in the 81st percentile of all CPUs, with its nearest rival being the AMD Ryzen 7 5800X, which scores 29123, a delta of -0.1%.

The CPU's performance characteristics directly explain the frame rate patterns. The high 1080p Low result of 293 FPS indicates the CPU can process the game's logic and draw calls at a very high rate when the GPU is not heavily loaded. However, the inability to scale to higher settings at 1080p without a significant FPS drop suggests a bottleneck. At 1080p High, the average is 188 FPS, which is 105 FPS lower than Low. This is a substantial gap that cannot be attributed to GPU load alone, as the RTX 5090 is more than capable of handling High settings at 1080p with much higher output. The CPU's limited boost clock and mobile-oriented design are likely the culprits.

The Passmark single-thread score of 3521 provides context for the CPU's gaming performance. While the multi-threaded score is respectable for a mobile chip, the single-thread performance is what matters most for frame pacing in many titles. The data indicates that the Core Ultra 5 135H cannot consistently feed the RTX 5090 at 1080p with higher quality presets, resulting in the CPU becoming the limiting component. At 4K, where the GPU workload is substantially higher, the CPU's limitations are less apparent, allowing the GPU to become the primary driver of performance. The 28 W TDP also suggests that sustained performance may be lower than peak boost clocks, which could explain the frame rate drops when transitioning from Low to High settings.

How This Combo Ranks

The combined performance of this CPU and GPU places it at rank 581 out of 2939 tested combos in Minimum. This ranking, which falls in the top 20% of all tested configurations, is notable given the mismatched nature of the components. The high rank is primarily driven by the GPU's immense power, which pushes the system to high frame rates at lower resolutions. However, the ranking also highlights the CPU's limiting role.

A combo with a more balanced processor would likely rank higher, as the RTX 5090's potential is not fully realized at 1080p. The fact that this pairing ranks 581st despite having a top-tier GPU suggests that many other combinations with slightly weaker GPUs but stronger CPUs achieve better overall performance in this game. The data shows that at 1440p and 4K, the system performs well, but the 1080p results are where the rank is likely dragged down. The CPU's position in the 81st percentile, combined with the GPU's 92nd percentile, indicates a significant imbalance. The benchmark results confirm that the GPU is the dominant contributor to the combo's rank, but the CPU prevents it from being a top-tier performer in CPU-bound scenarios.

Settings Recommendations

The measured data provides a clear hierarchy for the best experience. For players seeking the highest possible frame rates, 1080p with Low settings delivers an average of 293 FPS, which is ideal for competitive play or high-refresh-rate monitors. However, this comes at a significant visual quality cost. A more balanced approach at 1080p is Medium settings, which offers an average of 224 FPS with a minimum of 190 FPS, providing a smooth experience with better visuals than Low.

At 1440p, the Medium preset is the standout choice. It provides an average of 144 FPS with a minimum of 123 FPS, which is an excellent balance for most gamers. This offers a substantial improvement in visual fidelity over 1080p while maintaining high frame rates. The High preset at 1440p, with an average of 121 FPS, is also viable but does not offer the same headroom above 144 Hz. The Ultra preset at 1440p, with 92 FPS, is playable but represents a compromise on smoothness.

For 4K gaming, the Medium preset is the only reasonable option for a consistently smooth experience, with an average of 78 FPS and a minimum of 66 FPS. The High preset at 4K, with 65 FPS, is borderline, and the Ultra preset at 50 FPS is not recommended for action-oriented gameplay. Given the CPU bottleneck observed at lower resolutions, the best experience is found at 1440p with Medium settings. This resolution and preset combination allows the GPU to stretch its legs while the CPU is not as heavily taxed, resulting in the most balanced performance with an average of 144 FPS. The 1080p Medium setting is the best choice for high-refresh-rate displays, but 1440p Medium offers the ideal mix of visual quality and frame rate for most users.
