Rust

The AMD Radeon RX 7900M paired with the Intel Core Ultra X7 368H delivers a wide spread of performance in Rust, ranging from a highly playable 185 FPS average at 1080p Low to a demanding 32 FPS average at 4K Ultra. The measured data shows this combo ranks 1189th out of 2953 tested combinations, placing it in the upper-middle tier of systems for this survival title, with the GPU sitting in the 94th percentile and the CPU in the 87th percentile of their respective categories.

Resolution Scaling

The performance drop from 1080p to 4K is dramatic and clearly illustrates where the bottleneck shifts as pixel count rises. At Low settings, the average frame rate falls from 185 FPS at 1920x1080 to 127 FPS at 2560x1440, a reduction of 58 FPS, and then to 75 FPS at 3840x2160, another 52 FPS drop. This steep decline indicates that at 1080p, the system is not fully GPU-bound, as the RX 7900M has headroom to render many more frames, but at 4K, the rendering load becomes severe enough to cut performance by roughly 59% compared to 1080p.

The pattern holds across all settings presets. At High settings, the average FPS goes from 105 at 1080p down to 72 at 1440p and then to 43 at 4K. The Ultra preset shows the most constrained scaling, with 80 FPS at 1080p, 55 FPS at 1440p, and just 32 FPS at 4K. The relative drop from 1080p to 4K is consistent, hovering around a 60% reduction in average frame rate, which suggests that the CPU is capable of feeding the GPU adequately at lower resolutions, but the GPU's raw throughput becomes the limiting factor as resolution increases.

The data for Medium settings includes minimum and maximum frame rate readings, offering a closer look at frame pacing. At 1080p Medium, the average is 124 FPS with a minimum of 105 and a maximum of 143, showing a tight 38 FPS spread. At 1440p Medium, the average drops to 85 FPS with a 73 to 98 range, and at 4K Medium, the average falls to 50 FPS with a 43 to 58 range. The consistency of the frame time variance across resolutions suggests that the engine's frame pacing remains stable even when the average frame rate is cut by more than half.

CPU Role

The Intel Core Ultra X7 368H is a 16-core, 16-thread processor based on the Panther Lake architecture, built on Intel's 3 nm process. It has a base clock of 2.00 GHz and a boost clock of 5.00 GHz, with a TDP of 25 W. The cache hierarchy includes 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3 cache, which is a substantial amount for feeding the GPU in a game like Rust.

Benchmark results show the CPU performing at the 87th percentile of all CPUs, with an average benchmark score of 40518. Its nearest rival, the Intel Core 7 253PE, scores 40557, which is just 0.1% higher, indicating the 368H is essentially tied with that chip. The AMD Ryzen 9 7940H scores 40431, putting the 368H 0.2% ahead, and the Intel Xeon 6507P also scores 40426, again 0.2% behind the 368H.

In Rust, the CPU's role is evident in the frame rate differences between Low and Ultra settings at the same resolution. At 1080p, the Low preset hits 185 FPS average, likely limited by the engine's draw call overhead, while the Ultra preset drops to 80 FPS. The jump from Low to Medium at 1080p costs 61 FPS, while the jump from Medium to High costs 19 FPS, and High to Ultra costs 25 FPS. This non-linear scaling suggests the CPU is well-equipped to handle the game's simulation and entity logic, but the GPU becomes more involved as shadow quality and texture detail increase.

The multi-threaded scores are particularly relevant for Rust, which is known for its heavy server-side and client-side simulation. The Cinebench R23 multi-core score of 28221 and the Passmark multi-thread score of 32956 indicate strong parallel processing capability. The Passmark integer math score of 88083 and floating point math score of 105681 further support the idea that the CPU can handle the game's physics and AI calculations without becoming a major bottleneck at lower resolutions.

Measured FPS Breakdown

At 1920x1080, the system delivers its best performance. The Low preset averages 185 FPS, which is the highest recorded average in the entire dataset. Medium drops to 124 FPS, with a minimum of 105 and maximum of 143. High averages 105 FPS, and Ultra brings up the rear at 80 FPS. The gap between Low and Ultra at 1080p is 105 FPS, showing that the settings preset has a massive impact on performance.

Moving to 2560x1440, all presets see a noticeable reduction. Low averages 127 FPS, which is still very smooth, while Medium averages 85 FPS with a range of 73 to 98. High averages 72 FPS, and Ultra drops to 55 FPS. The spread between Low and Ultra at 1440p is 72 FPS, a smaller absolute gap than at 1080p but still significant. The 1440p results demonstrate that the RX 7900M can handle high refresh rate gaming at this resolution on lower presets.

At 3840x2160, the performance takes a significant hit across the board. Low is the only preset that remains above 60 FPS, averaging 75 FPS. Medium averages 50 FPS with a minimum of 43 and maximum of 58. High averages 43 FPS, and Ultra drops to 32 FPS. The difference between Low and Ultra at 4K is 43 FPS, and the system cannot maintain a consistent 60 FPS experience at this resolution on any preset other than Low.

The Medium preset is the only one with complete min/max data at every resolution. At 1080p, the min is 105 and max is 143; at 1440p, the min is 73 and max is 98; at 4K, the min is 43 and max is 58. The frame rate ranges are proportionally similar across resolutions, indicating that the engine's frame time variance scales with the average FPS rather than introducing stutter at higher resolutions.

GPU Role

The AMD Radeon RX 7900M is a high-end mobile GPU based on the RDNA 3.0 architecture, using the Navi 31 chip with a 5 nm process from TSMC. It packs 4608 shading units, 288 TMUs, and 192 ROPs, with 72 ray tracing cores. The GPU has a base clock of 1825 MHz and a boost clock of 2090 MHz, with memory running at 2250 MHz or 18 Gbps effective on a 256-bit bus, providing 576.0 GB/s of bandwidth across 16 GB of GDDR6 memory.

This GPU sits in the 94th percentile of all GPUs, with an average benchmark score of 97487. Its closest rival in the data is the AMD Radeon Pro VII, which scores 97131, a delta of 0.4% in favor of the RX 7900M. The NVIDIA Quadro RTX 6000 scores 101872, putting the RX 7900M 4.3% behind, while the AMD Radeon Instinct MI60 scores 92466, which is 5.4% lower than the RX 7900M.

The GPU's role in Rust is most apparent when examining the resolution scaling. At 1080p Low, the system achieves 185 FPS, which likely approaches the CPU's limit for frame generation. However, when the resolution increases to 4K, the GPU's fill rate and bandwidth become the limiting factors. The 576.0 GB/s of memory bandwidth is substantial, but the 4K Ultra preset at 32 FPS suggests the GPU is heavily taxed by the game's high-resolution textures and shadow rendering.

The 16 GB of VRAM is more than sufficient for Rust at any resolution, as the game's texture budgets are unlikely to exceed this capacity even at 4K Ultra. The pixel rate of 401.3 GPixel/s and texture rate of 601.9 GTexel/s are high figures that should handle the game's geometry and post-processing effects, but the measured FPS data shows that the GPU cannot maintain high frame rates at 4K with maxed settings, indicating that the rendering workload is intense.

Settings Recommendations

For players targeting 60 FPS average as a baseline, the data strongly points to 1920x1080 as the only resolution where all presets clear this threshold. At 1080p, even the Ultra preset averages 80 FPS, providing a comfortable margin above 60 FPS. The Medium preset at 1080p offers a balanced experience at 124 FPS average, with a minimum of 105 FPS that ensures smooth gameplay without dips below 60.

At 2560x1440, the recommended approach is to stick with Low or Medium settings. The Low preset averages 127 FPS, which is excellent for high refresh rate monitors, while Medium averages 85 FPS and keeps the minimum above 70 FPS. The High preset at 1440p drops to 72 FPS average, which is still playable, but the Ultra preset falls to 55 FPS, making it a poor choice for maintaining a consistent 60 FPS experience.

For 4K gaming, the data suggests using the Low preset, which averages 75 FPS. This is the only 4K preset that provides a comfortable playable experience. The Medium preset at 4K averages 50 FPS, which may be acceptable for some players, but the minimum of 43 FPS indicates potential stutter in busy scenes. The High and Ultra presets at 4K, at 43 and 32 FPS respectively, are not recommended for competitive play.

The best overall experience per the measured rows appears to be 1440p Medium, which offers 85 FPS average with a tight 73-98 FPS range. This provides a good balance between visual quality and performance, leveraging the GPU's capabilities without pushing it to its limits. For players who prioritize frame rate above all else, 1080p Low at 185 FPS is the clear choice, while those who want the highest visual fidelity should accept the 4K Low or 1440p High compromise.
