# Rust Performance Analysis: Intel Core Ultra 7 155H + NVIDIA GeForce RTX 4060 Mobile

This combination of Intel Core Ultra 7 155H and NVIDIA GeForce RTX 4060 Mobile delivers playable frame rates across most settings in Rust, though 4K Ultra remains beyond reach. The measured data shows a system that scales predictably with resolution and settings, with the CPU providing solid headroom at lower resolutions while the GPU becomes the primary constraint at 4K. The combo ranks 2282nd out of 3723 tested combinations, placing it in the lower-middle portion of the database.

Resolution Scaling

The frame rate progression from 1080p to 4K reveals a classic GPU-bound scaling pattern at higher settings, with CPU influence becoming more apparent at lower presets. At Low settings, the average FPS drops from 145 at 1920x1080 to 100 at 2560x1440, a 31% reduction, then to 59 at 3840x2160, another 41% drop from 1440p. This steep decline at Low settings suggests that even with reduced graphical load, the GPU's rendering capacity becomes the limiting factor as pixel count increases.

At High settings, the scaling is more moderate in percentage terms: 82 FPS at 1080p drops to 57 at 1440p (30% reduction) and then to 33 at 4K (42% reduction from 1440p). The Medium preset follows a similar trajectory: 98 FPS at 1080p, 67 at 1440p (32% drop), and 40 at 4K (40% drop). The Ultra preset shows the most dramatic falloff: 63 FPS at 1080p, 43 at 1440p (32% drop), and 25 at 4K (42% drop).

The consistent 30-32% reduction from 1080p to 1440p across all settings, followed by a 40-42% reduction from 1440p to 4K, indicates that pixel throughput scales almost linearly with resolution. This behavior is characteristic of a GPU-limited scenario at every preset level. The fact that Low settings at 4K (59 FPS) still outperforms Ultra at 1080p (63 FPS) by only 6% highlights how resolution dominates over settings in determining final frame rates.

The data suggests that at 1080p, the CPU has sufficient headroom to feed the GPU, as evidenced by the wide spread between Low (145 FPS) and Ultra (63 FPS). This 130% performance gap at 1080p narrows to 69% at 1440p (100 vs 43 FPS) and further to 136% at 4K (59 vs 25 FPS), indicating that the GPU's workload becomes increasingly dominant as resolution rises.

How This Combo Ranks

With a combo rank of 2282 out of 3723 tested combinations, this system sits in the 61st percentile of all CPU-GPU pairings tested in Rust. This places it firmly in the middle of the field, which aligns with the measured frame rates showing playable performance at most settings but no standout numbers at 4K Ultra.

The ranking reflects a balanced pairing where neither component dramatically bottlenecks the other. The Intel Core Ultra 7 155H's CPU benchmark scores place it near the 83rd percentile among all CPUs, with an average benchmark score of 32697. Its nearest rivals include the Intel Core i5-14600T (score 32707, delta 0%), the AMD Ryzen AI 7 PRO 360 (score 32662, delta 0.1%), the AMD Ryzen 5 7400F (score 32750, delta -0.2%), and the AMD Ryzen 7 PRO 6850H (score 32812, delta -0.4%). These near-identical scores indicate the 155H performs essentially on par with its closest competition.

The GPU's percentile ranking is lower at 67th among all GPUs, with an average benchmark score of 22729. Its nearest rivals include the NVIDIA GeForce RTX 2080 (score 22895, delta -0.7%), the AMD Radeon RX 7700 XT (score 22549, delta 0.8%), the Intel Arc B580 (score 23021, delta -1.3%), and the NVIDIA GeForce RTX 5060 Mobile (score 22435, delta 1.3%). The RTX 4060 Mobile sits within 1.3% of all these competitors, making it a very middle-of-the-pack mobile GPU.

The combination's rank of 2282 out of 3723 suggests that while the CPU is relatively strong (83rd percentile), the GPU's more modest 67th percentile pulls the overall combo down. This is consistent with Rust's tendency to be GPU-bound at higher resolutions, as seen in the resolution scaling data.

CPU Role

The Intel Core Ultra 7 155H is a 16-core, 22-thread processor based on the Meteor Lake architecture, manufactured on Intel's 7 nm process. Its base clock of 3.80 GHz can boost up to 4.80 GHz, with a 28 W TDP typical for mobile processors. The cache hierarchy includes 112 KB L1 per core, 2 MB L2 per core, and 24 MB of shared L3 cache, which provides ample capacity for game data.

In CPU benchmarks, the 155H demonstrates strong multi-threaded performance with a Cinebench R23 multi-core score of 15028 and a single-core score of 1743. PassMark results show a multi-thread score of 24873 and a single-thread score of 3468, with the physics test registering 1727. These scores indicate solid all-around performance that should handle Rust's simulation and entity processing demands.

The CPU's percentile ranking of 83rd among all CPUs confirms it is a capable processor for gaming workloads. Its nearest rivals in the database include the Intel Core i5-14600T and AMD Ryzen 5 7400F, both with near-identical average scores. This places the 155H in a competitive position within the mobile CPU landscape.

For Rust specifically, the CPU's 16 cores and 22 threads provide substantial parallel processing capability. Rust's open-world survival gameplay involves significant CPU work for entity management, world streaming, and physics calculations. The 155H's high multi-threaded scores suggest it can handle these tasks without becoming the primary bottleneck at most resolutions.

However, the measured FPS data shows that at 1080p Low settings, the system achieves 145 FPS, which is below what a top-tier desktop CPU might produce. This indicates that while the CPU is strong, it does impose some ceiling at very high frame rates, though the GPU's capabilities limit overall performance more significantly at higher resolutions.

Measured FPS Breakdown

At 1920x1080, the system delivers its best performance. Low settings produce an average of 145 FPS, Medium achieves 98 FPS with a minimum of 83 and maximum of 112, High reaches 82 FPS, and Ultra drops to 63 FPS. The spread between Low and Ultra is 82 FPS, showing that settings have a substantial impact at this resolution.

Moving to 2560x1440, the frame rates drop predictably. Low settings yield 100 FPS, Medium averages 67 FPS with minimum 57 and maximum 77, High produces 57 FPS, and Ultra falls to 43 FPS. The difference between Low and Ultra narrows to 57 FPS, indicating that resolution scaling begins to compress the settings impact.

At 3840x2160, performance becomes more constrained. Low settings still manage 59 FPS, Medium averages 40 FPS with minimum 34 and maximum 46, High drops to 33 FPS, and Ultra bottoms out at 25 FPS. The Low-to-Ultra spread narrows further to 34 FPS, confirming that 4K resolution dominates over settings in determining final frame rates.

The Medium preset consistently provides a measurable minimum FPS at each resolution: 83 at 1080p, 57 at 1440p, and 34 at 4K. This data point is valuable for understanding frame time consistency, as these minimums suggest the system maintains reasonably stable performance rather than experiencing severe drops.

Comparing settings across resolutions, the Low preset at 4K (59 FPS) outperforms the Ultra preset at 1440p (43 FPS) by 37%, and the Medium preset at 1440p (67 FPS) outperforms the High preset at 4K (33 FPS) by 103%. These cross-resolution comparisons illustrate the significant performance cost of 4K rendering.

DirectX performance varies by version: DirectX 9 scores 216, DirectX 10 scores 107, DirectX 11 scores 157, and DirectX 12 scores 73.

The GPU's 67th percentile ranking places it slightly below the midpoint of all GPUs. Its nearest rivals include the desktop RTX 2080 (delta -0.7%), RX 7700 XT (delta 0.8%), Arc B580 (delta -1.3%), and RTX 5060 Mobile (delta 1.3%). These small deltas show that the 4060 Mobile performs almost identically to these competitors in synthetic benchmarks.

For Rust, the GPU's 8 GB VRAM capacity is sufficient for the game's texture and geometry demands at all tested settings. The 256.0 GB/s memory bandwidth provides adequate throughput for the game's streaming requirements. The measured FPS data confirms the GPU is the primary bottleneck at 4K, where even Low settings only achieve 59 FPS, and the scaling pattern shows GPU-bound behavior across all resolutions.

Settings Recommendations

Based on the measured data, the optimal settings depend on the target resolution and desired frame rate. For players prioritizing smooth performance at 1080p, the Medium preset offers an excellent balance with 98 FPS average and a minimum of 83 FPS. This provides a comfortable margin above 60 FPS while maintaining visual quality. The High preset at 82 FPS is also viable for those wanting better visuals, though the minimum FPS is not reported.

At 1440p, the Medium preset again appears to be the sweet spot, delivering 67 FPS average with a minimum of 57 FPS. This keeps the experience above 60 FPS for most of the time, with brief dips below that threshold. The Low preset at 100 FPS is the choice for competitive play, while High at 57 FPS and Ultra at 43 FPS are marginal for consistent 60+ FPS gameplay.

For 4K gaming, the data suggests that only the Low preset provides a playable experience at 59 FPS. The Medium preset at 40 FPS is borderline, and the High preset at 33 FPS and Ultra at 25 FPS fall below acceptable thresholds for most players. The 4K Low setting is the only option that approaches 60 FPS, making it the recommended choice for 4K displays.

Comparing presets across all resolutions, the Medium setting consistently provides the best combination of visual quality and performance. It offers a 20-21% improvement over High at each resolution (98 vs 82 at 1080p, 67 vs 57 at 1440p, 40 vs 33 at 4K) while maintaining playable minimums at 1080p and 1440p. The Ultra preset's performance cost is substantial, delivering 36-37% lower FPS than Medium at every resolution, making it difficult to recommend unless visual fidelity takes absolute priority over smoothness.
