Rust

The Intel Core Ultra 5 135H paired with the NVIDIA GeForce RTX 4090 Mobile delivers a strong, high-refresh-rate experience in Rust at 1080p, but the data shows a clear trade-off between visual fidelity and frame rate as resolution increases. This combination ranks in the 903rd position out of 3723 tested combos, placing it comfortably in the top quarter of all systems tested for this title. The measured results indicate that this is a capable pairing for competitive play, but settings management is crucial for maintaining smooth performance at higher resolutions.

Settings Recommendations

The measured FPS data for this combo in Rust points to Medium as the optimal preset for most users, particularly those gaming at 1440p or 4K. At 2560x1440, the Medium preset delivers an average of 105 FPS with a minimum of 89 FPS and a maximum of 120 FPS. This represents a 19% performance improvement over High settings at the same resolution, which dips to an average of 88 FPS. The minimum frame rate of 89 FPS on Medium is notably above the 60 FPS threshold, providing a consistent experience that avoids the stutter associated with frame drops.

For 1080p users, High is the recommended starting point, as it yields an average of 128 FPS while maintaining better visual quality than Medium. However, the jump to Ultra at 1080p costs 30 FPS on average (98 FPS vs 128 FPS), which is a significant penalty for marginal visual gains in a game like Rust where clarity and reaction time matter. The data shows that Low settings at 1080p produce 204 FPS average, but this sacrifices too much visual information for a competitive edge, as spotting distant players becomes harder.

At 4K, the situation is more constrained. The Medium preset at 3840x2160 produces an average of 62 FPS, with a minimum of 52 FPS and a maximum of 71 FPS. This is playable but not ideal for fast-paced encounters. High settings at 4K drop to 52 FPS average, which is borderline for smooth gameplay, while Ultra falls to 40 FPS average, which is too low for a survival shooter where split-second reactions are required. For 4K, Medium is the only practical choice, and even then, the 52 FPS minimum suggests occasional dips that could be problematic.

The data strongly indicates that this combo is best utilized at 1080p or 1440p with Medium or High settings, where the frame rates are high enough to leverage the RTX 4090 Mobile’s capabilities without being bottlenecked by the Ultra 5 135H.

GPU Role

The NVIDIA GeForce RTX 4090 Mobile is the dominant component in this pairing, and the benchmark results reflect its substantial performance headroom. With 16 GB of GDDR6 memory on a 256-bit bus, the GPU has a memory bandwidth of 576.0 GB/s, which is ample for Rust’s asset streaming and large map loads. The GPU’s 9728 shading units and 112 ROPs are tasked with rendering the game’s complex scenes, and the 32.98 TFLOPS of FP32 compute power is more than sufficient for this title.

The clock speeds of the RTX 4090 Mobile are notable: a base clock of 1335 MHz and a boost clock of 1695 MHz. The data shows that the GPU is not the limiting factor at lower resolutions, as the FPS scales dramatically with resolution changes. For instance, moving from 1080p High (128 FPS) to 1440p High (88 FPS) represents a 31% drop, which is a typical GPU-bound scaling pattern. However, the RTX 4090 Mobile’s performance percentile of 84 places it well above average, and its nearest rivals include the NVIDIA RTX A6000 (deltaPct of -0.9) and the NVIDIA Quadro M6000 (deltaPct of 0.8), indicating it sits in a high-performance tier.

The GPU’s VRAM capacity of 16 GB is a critical advantage in Rust, which is known for its memory-hungry nature due to large player bases and complex structures. The data shows that even at 4K Ultra, the game runs at 40 FPS average, which is likely limited by the GPU’s raw compute rather than memory capacity, as the 16 GB buffer is unlikely to be exhausted at these settings. The GPU’s Ada Lovelace architecture, with its 76 RT cores and 304 tensor cores, provides headroom for future updates or graphical enhancements, although the current benchmark data does not show ray tracing performance.

How This Combo Ranks

The combo rank of 903 out of 3723 tested configurations places this system in the 75.7th percentile of all tested combos for Rust. This is a strong showing, but it is not at the absolute top tier, which is reserved for desktop-class components or more aggressively clocked mobile parts. The data suggests that while the RTX 4090 Mobile is a top-tier GPU, the Intel Core Ultra 5 135H holds the combo back from the very top positions.

To contextualize this rank, the CPU’s average benchmark score of 29093 places it just 0.1% behind the AMD Ryzen 7 5800X (score of 29123) and 0.5% ahead of the AMD Ryzen 5 5600XT (score of 28940). The Intel Core i5-13500HX is 0.6% ahead with a score of 29270. These are all desktop-class or high-end mobile CPUs, which indicates that the Ultra 5 135H is performing at a level that is competitive with older desktop parts, but it lacks the multi-core muscle of more recent flagship mobile CPUs.

In Rust, which is known to be CPU-heavy due to its simulation and networking code, the CPU’s performance is a significant factor. The combo rank of 903 suggests that many other tested systems, likely those with stronger CPUs like the Core i9 or Ryzen 9 series, achieve higher frame rates in this specific title. The GPU’s percentile rank of 84 is higher than the combo’s overall rank, which further reinforces that the CPU is the limiting factor in this pairing for Rust’s specific workload.

Measured FPS Breakdown

The measured FPS data provides a clear picture of performance across resolutions and settings. At 1920x1080, the results are as follows:

• Low: 204 FPS average
• Medium: 152 FPS average (min 129, max 175)
• High: 128 FPS average
• Ultra: 98 FPS average

The 1080p data shows that the combo can easily drive high refresh-rate monitors, with even Ultra settings staying above 90 FPS. The jump from Low to Medium costs 52 FPS, which is significant, but the jump from Medium to High is a more manageable 24 FPS loss. The Ultra preset is 30 FPS slower than High, suggesting that the highest settings include effects that disproportionately tax the system.

At 2560x1440, the performance drops are more pronounced:

• Low: 156 FPS average
• Medium: 105 FPS average (min 89, max 120)
• High: 88 FPS average
• Ultra: 67 FPS average

1440p remains highly playable, with Medium and High both producing frame rates above 60 FPS. The minimum of 89 FPS on Medium is particularly solid, indicating that the combo can hold frame rates well in demanding scenes. Ultra at 67 FPS is still playable, but it lacks the headroom for drops that could occur in intense firefights or when large structures are loaded.

At 3840x2160, the limits of the combo are reached:

• Low: 92 FPS average
• Medium: 62 FPS average (min 52, max 71)
• High: 52 FPS average
• Ultra: 40 FPS average

4K is only viable with Low or Medium settings. The 92 FPS on Low is surprisingly high, but the visual quality is severely reduced. Medium at 62 FPS is the sweet spot for 4K, but the 52 FPS minimum indicates that there will be moments of slowdown. The 40 FPS average on Ultra is below the threshold for smooth gameplay and is not recommended.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals a GPU-bound system, but with a notable CPU influence at lower resolutions. Moving from 1080p High (128 FPS) to 1440p High (88 FPS) results in a 31.3% drop. From 1440p High to 4K High (52 FPS), the drop is 40.9%. This progressive decline is characteristic of a GPU-bound scenario, where each pixel increase adds significant rendering load.

However, the scaling is not perfectly linear, which suggests some CPU limitation at 1080p. The drop from 1080p Low (204 FPS) to 1440p Low (156 FPS) is 23.5%, which is less than the drop from 1080p High to 1440p High. This is because at Low settings, the GPU is less stressed, and the CPU becomes a larger factor in the frame rate. The 204 FPS at 1080p Low is likely near the CPU’s maximum frame output for this game, as the Core Ultra 5 135H’s single-thread performance (Cinebench R23 single-core score of 1700) limits how many frames the CPU can feed to the GPU.

The data shows that the RTX 4090 Mobile has significant headroom at 1080p, as the FPS does not scale linearly with resolution drops. For instance, dropping from 1080p to 1440p at Medium settings only costs 47 FPS (152 to 105), while dropping from 1440p to 4K at Medium costs 43 FPS (105 to 62). This suggests that at 1080p, the GPU is not fully utilized, and the CPU is the primary bottleneck. At 4K, the GPU is fully saturated, and the CPU is no longer the limiting factor.

CPU Role

The Intel Core Ultra 5 135H is a 14-core, 18-thread processor based on the Meteor Lake architecture, with a base clock of 3.60 GHz and a boost clock of 4.60 GHz. Its Cinebench R23 multi-core score of 11875.5 and single-core score of 1700 place it in the 81st percentile of all CPUs, which is respectable for a mobile part. However, its PassMark single-thread score of 3521 is modest compared to more powerful desktop parts, and this is where Rust’s performance is likely constrained.

Rust is a game that relies heavily on single-threaded performance for its core simulation, physics, and networking. The benchmark data supports this, as the FPS at 1080p Low (204 FPS) is likely limited by the CPU’s single-thread capabilities. The CPU’s nearest rivals include the AMD Ryzen 7 5800X, which has a similar average score, but the 5800X typically has stronger single-core performance in gaming. The 0.1% deltaPct between the two is negligible, but in a game like Rust, even small single-thread differences can translate to noticeable FPS changes.

The CPU’s 18 MB of shared L3 cache is adequate, but not exceptional. The data shows that the combo’s rank of 903 out of 3723 is primarily due to the CPU’s limitations in Rust’s CPU-bound scenarios. The GPU is capable of much higher frame rates, as evidenced by the 4K Low result of 92 FPS, which is still quite high and indicates the GPU is not the limiting factor at lower resolutions. The CPU’s 28W TDP is low, which helps with thermal management in a laptop, but it also means the processor cannot sustain high clocks for extended periods under heavy load.

In summary, the Intel Core Ultra 5 135H provides sufficient performance for casual gaming, but in Rust, it prevents the RTX 4090 Mobile from reaching its full potential at 1080p. At 1440p and 4K, the GPU becomes the bottleneck, and the CPU’s role diminishes. For users prioritizing maximum FPS in Rust, a stronger CPU with higher single-thread performance would be beneficial, but for balanced gaming at high resolutions, this combo is a solid performer.
