Rust

The AMD Radeon 880M paired with the Intel Core Ultra X7 368H delivers playable frame rates in Rust only at the lowest settings and resolution, with a clear ceiling imposed by the integrated GPU. At 1080p Low, the combo produces an average of 64 FPS, which is the only measured configuration that exceeds the 60 FPS threshold. All other tested settings and resolutions fall below this mark, with the highest quality presets at 4K dropping to as low as 11 FPS. The performance hierarchy across the measured data is consistent: resolution scaling and quality presets have a profound impact, and the iGPU's architectural limits become the primary bottleneck in nearly every scenario.

Settings Recommendations

Based on the measured FPS rows, the optimal experience for this combo in Rust is achieved at 1080p with the Low preset. This configuration yields an average of 64 FPS, which is the only setting that provides a smooth, responsive frame rate suitable for the fast-paced interactions typical of survival gameplay. The next closest option, 1080p Medium, delivers an average of 43 FPS, which is 21 FPS lower and may introduce noticeable stutter in combat or when multiple entities are on screen.

At 1440p, the data indicates that even the Low preset struggles to maintain acceptable performance, averaging 44 FPS. This is a 31% reduction from the 1080p Low result, and the higher resolution does not provide a visual benefit substantial enough to justify the frame rate loss. For users with 1440p displays, the recommendation is to run the game at 1080p and rely on display scaling, as the performance gap is significant.

The High and Ultra presets are not viable at any resolution in this configuration. At 1080p High, the average FPS is 36, while Ultra drops to 28 FPS. At 4K, these presets produce averages of 15 and 11 FPS, respectively, which are effectively unplayable. The Medium preset at 1080p, with a min FPS of 37 and a max of 50, offers a more stable frame time distribution than High, but the average of 43 FPS still falls short of the smoothness provided by Low.

For players prioritizing visual fidelity over frame rate, the Medium preset at 1080p is the highest quality option that maintains a minimum above 30 FPS. However, the data strongly suggests that the Low preset is the only setting that aligns with the hardware's capabilities, providing a consistent 64 FPS average that avoids the frame pacing issues seen in the 37-50 FPS range of Medium.

FAQ

Q: What is the best resolution and settings combination for this hardware in Rust?

A: The measured data shows that 1080p with Low settings produces an average of 64 FPS, the highest score in the dataset. This is the only combination that exceeds 60 FPS, making it the recommended configuration for smooth gameplay.

Q: How does the combo perform at 4K resolution?

A: At 4K, the average FPS ranges from 11 at Ultra to 26 at Low settings. The Medium preset averages 18 FPS, with a minimum of 15 and a maximum of 20. These results indicate that 4K is not a practical target for this integrated GPU.

Q: Is the CPU or GPU the limiting factor in Rust?

A: The benchmark data indicates the GPU is the primary constraint. The CPU has a strong multi-core score of 28,221 in Cinebench R23, yet the frame rates collapse at higher resolutions. This pattern suggests the 880M's compute throughput is insufficient for the game's rendering demands.

Q: What frame rate can be expected at 1440p with Medium settings?

A: The measured average is 30 FPS, with a minimum of 25 and a maximum of 34. This is below the smoothness threshold and shows that 1440p Medium is only marginally playable in less demanding scenes.

Q: How does the 1080p Ultra preset compare to 1080p Low?

A: The Ultra preset averages 28 FPS, while Low averages 64 FPS. This represents a 36 FPS difference, or a 56% reduction in frame rate, for the higher visual quality. The trade-off is substantial and favors Low for gameplay.

Q: Are there any settings that provide a stable frame rate above 50 FPS?

A: Based on the data, only 1080p Low achieves an average above 50 FPS, at 64 FPS. The 1080p Medium preset has a maximum of 50 FPS but an average of 43, indicating that it does not consistently maintain that level.

How This Combo Ranks

The combo ranks 2878 out of 2953 tested combinations in Rust, placing it in the bottom 2.5% of all tested hardware pairings. This position reflects the fundamental mismatch between the game's engine demands and the integrated GPU's capabilities. The rank is derived from the measured FPS across all resolutions and settings, and the data shows a consistent shortfall compared to the field.

The ranking context is important for understanding the hardware's positioning. The CPU, Intel Core Ultra X7 368H, has an average benchmark score of 40,518 and sits at the 87th percentile of all CPUs, indicating strong processing power. The GPU, AMD Radeon 880M, has an average benchmark score of 8,436 and is at the 43rd percentile of all GPUs, which is a mid-to-low tier position. The disparity between the CPU's high percentile and the GPU's lower percentile explains why the combo ranks so poorly in a game that is heavily GPU-bound.

In practical terms, this rank means that most other tested combos deliver higher frame rates in Rust. The nearest GPU rivals, such as the NVIDIA GeForce GTX 675MX with a score of 8,427 and a delta of 0.1%, and the AMD Radeon HD 8870M with a score of 8,462 and a delta of -0.3%, perform nearly identically in synthetic benchmarks. However, the measured FPS in Rust shows that the 880M, despite its modern architecture, does not overcome the game's specific optimization challenges.

The low rank also suggests that users with this combo will need to accept significant compromises. The data shows that even at the lowest settings, the frame rate is only competitive with older discrete GPUs, not modern integrated solutions or dedicated cards. For a game like Rust, which relies on persistent world simulation and frequent asset loading, the 2878 rank indicates that the experience will be constrained by the GPU's limited fill rate and shader throughput.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across three resolutions and four settings presets. At 1920x1080, the averages are 64 FPS for Low, 43 FPS for Medium, 36 FPS for High, and 28 FPS for Ultra. The Medium preset has a documented minimum of 37 FPS and a maximum of 50 FPS, showing a 13 FPS variance that could be perceptible during gameplay. The spread from Low to Ultra at 1080p is 36 FPS, which is the largest delta among all resolutions.

At 2560x1440, the averages decline to 44 FPS for Low, 30 FPS for Medium, 25 FPS for High, and 19 FPS for Ultra. The Medium preset at this resolution has a minimum of 25 FPS and a maximum of 34 FPS, a 9 FPS variance. The transition from 1080p to 1440p at Low settings results in a 20 FPS drop, from 64 to 44 FPS, which is a 31% reduction. This scaling pattern indicates that the GPU's pixel throughput is a limiting factor, as the increased resolution directly impacts the fill rate.

At 3840x2160, the averages are 26 FPS for Low, 18 FPS for Medium, 15 FPS for High, and 11 FPS for Ultra. The Medium preset has a minimum of 15 FPS and a maximum of 20 FPS, a 5 FPS variance. The drop from 1440p to 4K at Low settings is 18 FPS, from 44 to 26 FPS, representing a 41% reduction. At the Ultra preset, the drop from 1440p to 4K is 8 FPS, from 19 to 11 FPS, a 42% reduction.

The data reveals a consistent pattern: each step up in resolution incurs a near-proportional loss in frame rate. For instance, 1080p Low to 1440p Low loses 20 FPS, and 1440p Low to 4K Low loses 18 FPS. This linear degradation suggests that the GPU is operating at its maximum capacity even at the lowest settings, and any increase in workload directly translates to lower FPS.

Resolution Scaling

The resolution scaling data shows that the AMD Radeon 880M experiences severe frame rate degradation as pixel count increases. From 1080p to 1440p, the average FPS across all settings drops by an average of 34%. From 1440p to 4K, the average FPS drops by an additional 40%. This compounding effect means that the 4K Ultra preset, at 11 FPS, is only 17% of the performance of the 1080p Low preset, at 64 FPS.

The specific scaling behavior points to a GPU-bound scenario. The CPU, with a boost clock of 5.00 GHz and 16 cores, is unlikely to be the bottleneck at these frame rates. The fact that the FPS scales nearly linearly with resolution indicates that the GPU's pixel shading and memory bandwidth are the limiting factors. The 880M has a texture rate of 139.2 GTexel/s and a pixel rate of 46.40 GPixel/s, which are modest figures for modern gaming.

The data shows that the 1080p Low to 4K Low transition results in a 38 FPS drop, from 64 to 26 FPS. This is a 59% reduction. The 1080p Ultra to 4K Ultra transition results in a 17 FPS drop, from 28 to 11 FPS, a 61% reduction. The consistency of these percentages across different quality presets reinforces that resolution is the dominant factor, not the settings complexity.

For users, this means that the only viable path to higher frame rates is to reduce resolution. The 1440p Low preset at 44 FPS is the second-highest average in the dataset, but it still falls short of the 60 FPS target. The 1080p Medium preset at 43 FPS is nearly identical to the 1440p Low result, suggesting that the GPU is equally taxed by either higher resolution or higher quality settings.

CPU Role

The Intel Core Ultra X7 368H is a 16-core, 16-thread processor with a base clock of 2.00 GHz and a boost clock of 5.00 GHz. Its multi-core performance is strong, as evidenced by a Cinebench R23 score of 28,221, which places it at the 87th percentile of all CPUs. The single-core score of 3,984 in R23 indicates solid performance for latency-sensitive tasks, which is relevant for Rust's game logic and physics calculations.

The CPU's architecture, Panther Lake on a 3 nm process, provides a high instruction throughput. The Passmark multithread score of 32,956 and the single-thread score of 4,005 show balanced capabilities. However, in the measured FPS data, the CPU does not appear to be the limiting factor. This is evident from the fact that reducing resolution from 1080p to 4K at the same settings causes a significant FPS drop, which would not occur if the CPU were the bottleneck.

The CPU's memory bandwidth of 153.6 GB/s and dual-channel LPDDR5X support are adequate for feeding the iGPU. The 18 MB of shared L3 cache helps with data locality, but the game's asset streaming demands are more likely to stress the GPU's memory interface. The CPU's 25 W TDP is low, which is typical for a mobile processor, but the performance headroom is sufficient for the frame rates observed.

The nearest CPU rivals, such as the AMD Ryzen 9 7940H with a delta of 0.2% and the Intel Xeon 6507P with a delta of 0.2%, show that the 368H is competitive in synthetic benchmarks. Yet, in Rust, the combo's rank of 2878 out of 2953 indicates that the CPU's potential is not realized due to the GPU constraint. The CPU is capable of handling the game's simulation, but the GPU cannot render frames fast enough to utilize the available processing power.

GPU Role

The AMD Radeon 880M is an integrated GPU based on the RDNA 3.5 architecture, fabricated on a 4 nm process at TSMC. It has 768 shading units, 48 TMUs, and 16 ROPs, with a boost clock of 2900 MHz. The FP32 performance is 4.454 TFLOPS, which is modest for modern gaming. The GPU's memory is system-shared, with bandwidth described as system-dependent, meaning it relies on the CPU's memory bandwidth.

The GPU's benchmark scores reflect its mid-tier positioning. The Passmark G3D score is 7,615, and the 3DMark Steel Nomad DX12 score is 535. These scores place the GPU at the 43rd percentile of all GPUs, with an average benchmark score of 8,436. The nearest rivals, such as the NVIDIA GeForce MX330 with a delta of -0.3% and the AMD Radeon HD 8870M with a delta of -0.3%, indicate that the 880M is comparable to older discrete mobile GPUs.

In Rust, the GPU's limitations are immediately apparent. The measured FPS data shows that the GPU cannot maintain playable frame rates at higher settings. The 1080p Medium preset, with an average of 43 FPS and a minimum of 37 FPS, is the highest quality setting that stays above 30 FPS. The 4K Ultra preset, at 11 FPS, is a clear indication that the GPU's pixel throughput is insufficient for high-resolution rendering.

The GPU's 12 RT cores and support for DirectX 12 Ultimate (12_2) are modern features, but they do not benefit Rust, which is not a ray-tracing-heavy title. The texture rate of 139.2 GTexel/s and pixel rate of 46.40 GPixel/s are the physical limits that dictate the measured performance. The data shows a consistent pattern where increasing resolution or quality directly reduces FPS, confirming that the GPU is the bottleneck in this combo.
