Rust

Rust is a demanding survival title that stresses both CPU and GPU, and the data for the Intel Core Ultra 7 155H paired with the NVIDIA GeForce RTX 4070 reveals a system that delivers playable frame rates across most settings, but with clear limitations at the highest resolutions. The measured results show a wide performance spread, from a highly fluid 163 FPS at 1080p Low to a borderline 29 FPS at 4K Ultra, indicating that component scaling is heavily dependent on the chosen graphical preset. This analysis will break down the measured FPS data to understand where the bottleneck lies and what settings provide the best experience for this specific combination.

Resolution Scaling

The FPS drop from 1080p to 4K is significant and tells a clear story about how the RTX 4070 is being pushed. At Low settings, the average frame rate falls from 163 FPS at 1920x1080 to 112 FPS at 2560x1440, a drop of 51 FPS. Moving to 3840x2160, the average plummets to 66 FPS, which is a 97 FPS reduction from the 1080p baseline. This steep decline at Low settings suggests that the GPU is becoming the primary limiting factor as pixel count increases, even when the graphical load is otherwise light.

At High settings, the scaling is less steep but still pronounced. The average FPS goes from 92 at 1080p to 64 at 1440p, a 28 FPS drop, and then further down to 38 at 4K, a 54 FPS drop from 1080p. This pattern indicates that the RTX 4070 is consistently challenged by the higher resolutions, with the gap between 1440p and 4K being particularly wide. The data implies that while the CPU can keep up at lower resolutions, the GPU's rendering workload at 4K causes a substantial performance penalty.

The behavior at Medium and Ultra settings further confirms this. At Medium, the average drops from 109 FPS at 1080p to 75 FPS at 1440p, and then to 44 FPS at 4K. At Ultra, the decline is from 70 FPS to 48 FPS to 29 FPS across the same resolution steps. The consistent pattern of large FPS losses when moving to 4K, regardless of preset, suggests that the system is firmly GPU-bound at that resolution. The data indicates that for a smoother experience, users would need to prioritize either lower resolutions or lower graphical settings to alleviate the load on the RTX 4070.

GPU Role

The NVIDIA GeForce RTX 4070 features 12 GB of GDDR6X memory on a 192-bit bus, providing a memory bandwidth of 504.2 GB/s. The GPU's base clock is 1920 MHz with a boost clock of 2475 MHz. These specifications are central to understanding the performance data in Rust. The 12 GB VRAM allocation appears sufficient for the tested settings, but the data shows that the GPU's raw processing power, rather than memory capacity, is the key factor in the observed FPS dips at higher resolutions.

The benchmark results for the RTX 4070 show it sits in the 81st percentile of all GPUs, with an average benchmark score of 37648. Its nearest rivals in synthetic tests include the NVIDIA Tesla P4 with a delta of 0.1%, and the AMD Radeon RX Vega 56 with a delta of 0.4%. While these synthetic scores don't directly translate to game performance, they establish the RTX 4070 as a high-tier card. However, in Rust, the measured FPS data reveals that even this powerful GPU struggles to maintain high frame rates at 4K Ultra, where it averages only 29 FPS.

The GPU's clock speeds and memory bandwidth are put to the test by the game's rendering demands. The significant performance difference between Low (66 FPS) and Ultra (29 FPS) at 4K demonstrates how the GPU's workload scales with graphical fidelity. The data suggests that the RTX 4070's capabilities are best utilized at 1080p and 1440p, where it can deliver high frame rates on more demanding presets, rather than at 4K where the processing load becomes overwhelming.

Measured FPS Breakdown

At 1920x1080, the combo shows a strong performance range. On Low settings, the average FPS is 163, indicating a very fluid experience. Medium settings still provide a high average of 109 FPS, with minimum and maximum values of 93 and 126 FPS respectively. High settings bring the average down to 92 FPS, while Ultra settings result in an average of 70 FPS. This resolution offers the best balance of visual quality and performance, with all presets remaining above the 60 FPS threshold.

Moving to 2560x1440, the performance becomes more demanding. Low settings yield an average of 112 FPS, which is still excellent. The Medium preset averages 75 FPS, with a minimum of 64 and a maximum of 87 FPS. High settings drop the average to 64 FPS, and Ultra settings fall to 48 FPS. This resolution shows that High settings are still playable, but Ultra begins to push the system below the generally desired 60 FPS mark.

At 3840x2160, the system is clearly strained. The Low preset manages an average of 66 FPS, which is the only setting at this resolution to remain above 60 FPS. Medium settings average 44 FPS, with a minimum of 38 and maximum of 51 FPS. High settings average 38 FPS, and Ultra settings average only 29 FPS. The data at 4K shows that for a consistent experience, users would need to stay on Low settings, as all other presets result in frame rates that could be considered too low for fast-paced gameplay.

How This Combo Ranks

This specific combination of the Intel Core Ultra 7 155H and the NVIDIA GeForce RTX 4070 ranks 1547th out of 2953 tested combos in Rust.

The CPU has an average benchmark score of 32697 and is in the 83rd percentile of all CPUs, while the GPU is in the 81st percentile with an average score of 37648. Despite these solid individual scores, the in-game ranking suggests that the pairing may not be optimally balanced for Rust's specific workloads.

The nearest rival for the CPU is the Intel Core i5-14600T, which has an average score of 32707 and a delta of 0%, showing they are nearly identical in synthetic performance. The GPU's nearest rival is the NVIDIA Tesla P4, with a delta of 0.1%. While these synthetic benchmarks are close, the actual game performance, as measured by the combo's rank, indicates that there may be other factors at play, such as thermal throttling or driver overhead, that affect real-world results.

The rank of 1547 out of 2953 means that approximately 48% of tested combos perform better in Rust. This suggests that while the RTX 4070 is a powerful GPU and the Core Ultra 7 155H is a capable CPU, their combined performance in this specific game is not top-tier. The data implies that users with this combo should not expect to max out all settings at high resolutions, as the system will be limited by the GPU's ability to render at those levels.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend heavily on the target resolution and desired frame rate. For 1080p gaming, the Medium preset provides an excellent balance, with an average of 109 FPS and a minimum of 93 FPS. This ensures a smooth experience without the visual compromises of Low settings. High settings are also viable, averaging 92 FPS, but for those seeking the highest frame rates, Low at 163 FPS is the clear choice.

At 1440p, the High preset offers a good experience with an average of 64 FPS, though it is close to the 60 FPS threshold. For a more comfortable margin, the Medium preset averages 75 FPS and is recommended for consistent performance. Low settings remain an option for competitive play, averaging 112 FPS, but at the cost of visual fidelity. Ultra settings should be avoided at this resolution due to the sub-60 FPS average.

For 4K gaming, the data strongly recommends using Low settings, which is the only preset to average above 60 FPS at 66 FPS. The Medium preset averages 44 FPS, which may be acceptable for less demanding gameplay, but it dips to a minimum of 38 FPS. High and Ultra settings are not recommended at this resolution, as their averages of 38 FPS and 29 FPS respectively would likely result in a choppy experience. The data clearly shows that 4K gaming with this combo requires significant graphical compromises.

CPU Role

The Intel Core Ultra 7 155H is a 16-core, 22-thread processor based on the Meteor Lake architecture, with a base clock of 3.80 GHz and a boost clock of 4.80 GHz. It has a 24 MB shared L3 cache and supports DDR5 memory. Its synthetic benchmark results are strong, with a Cinebench R23 multicore score of 15028 and a single-core score of 1743. The CPU's Passmark multithread score is 24873, placing it in the 83rd percentile of all CPUs.

In Rust, the CPU's role appears to be secondary to the GPU at higher resolutions, but it becomes more critical at 1080p. The high average FPS of 163 at 1080p Low suggests that the CPU is not a bottleneck in this scenario, as it can feed the GPU with enough data to achieve such high frame rates. However, the performance difference between Low and Ultra settings at 1080p (163 vs. 70 FPS) indicates that the GPU is still the main driver of performance changes.

The CPU's nearest rivals in synthetic benchmarks are the Intel Core i5-14600T and the AMD Ryzen AI 7 PRO 360, both with a delta of 0% or 0.1%. This shows that the Core Ultra 7 155H is competitive with other mid-range to high-end processors. The data implies that in Rust, the CPU is capable of handling the game's simulation and physics tasks, but it is not the primary factor limiting frame rates, especially as the resolution and graphical load increase. The bottleneck shifts firmly to the RTX 4070 at 1440p and 4K, where the CPU has more than enough headroom to keep up.
