Q: What is the largest performance gap between settings at a single resolution?

A: At 1920x1080, the spread from Low to Ultra is 135 FPS. The Low preset delivers 237 FPS average, while Ultra drops to 102 FPS. This represents a 57% reduction in frame rate when moving from the lowest to the highest quality settings at 1080p.

Q: Which resolution shows the smallest difference between Low and Ultra settings?

A: At 3840x2160, the gap between Low (96 FPS) and Ultra (41 FPS) is 55 FPS. This is the narrowest absolute spread across the three resolutions tested, though proportionally it is the steepest drop at 57% — identical to the 1080p percentage reduction.

Q: Does the RTX 5090 Mobile show a bigger performance advantage over its nearest rivals in synthetic tests or in Rust?

A: The GPU's average benchmark score is 45,152, which is 0.8% above the NVIDIA GeForce RTX 4070 Ti (44,795) and 1.8% below the NVIDIA RTX 5880 Ada Generation (45,972). In Rust specifically, the measured frame rates at 2560x1440 High (92 FPS) are consistent with this mid-pack positioning among the listed rivals.

Q: What is the CPU's percentile ranking among all processors, and what does that indicate for Rust?

A: The AMD Ryzen AI Max+ 395 sits at the 95th percentile among all CPUs, with an average benchmark score of 77,740. This puts it 1.6% ahead of the AMD Ryzen Threadripper PRO 9945WX (76,513) and 1.7% behind the Intel Core i9-14900K (79,097). For Rust, this high percentile suggests the processor rarely becomes the limiting factor, especially at lower resolutions.

Q: Are the FPS numbers measured or estimated?

A: The data is marked as "dataIsMeasured: true," meaning the frame rates come from actual benchmark runs rather than theoretical calculations. The Medium settings rows include min and max FPS values (e.g., 135-183 at 1080p), providing additional confidence in the measurement methodology.

GPU Role

The NVIDIA GeForce RTX 5090 Mobile brings 24 GB of GDDR7 memory across a 256-bit bus, delivering 896.0 GB/s of bandwidth. This is a mobile implementation of the GB203 chip built on TSMC's 5 nm process, containing 45,600 million transistors on a 378 mm² die. The GPU operates at a base clock of 990 MHz and a boost clock of 1515 MHz, with memory running at 1750 MHz (28 Gbps effective). The 10,496 shading units, 328 TMUs, and 112 ROPs provide the raw compute foundation for Rust's rendering workload.

In Rust specifically, the GPU's role becomes evident when comparing frame rates across quality presets. At 1920x1080, the jump from Low to High settings (237 to 134 FPS) shows a 43% performance cost for the visual improvements. The Medium preset at 1080p delivers 159 FPS, sitting almost exactly halfway between Low and High in terms of frame rate. This scaling pattern suggests the GPU has ample headroom at 1080p, with the CPU likely influencing the upper bounds of the Low preset's 237 FPS result.

The 24 GB frame buffer is substantial for Rust, which can be memory-hungry in large multiplayer servers with extensive bases and structures. At 3840x2160 Ultra, the combo still manages 41 FPS average, indicating the VRAM capacity is not a bottleneck at this resolution. The GPU's PassMark G3D score of 30,034 places it at the 84th percentile among all GPUs, which aligns with the strong but not top-tier positioning seen in the Rust results. The synthetic benchmarks show a balanced profile: 3DMark Steel Nomad DX12 score of 5,871, Geekbench OpenCL of 201,834, and Vulkan of 198,405. These numbers corroborate the measured Rust performance rather than suggesting any anomaly in game-specific optimization.

Resolution Scaling

The frame rate progression from 1920x1080 to 3840x2160 reveals how the workload shifts between CPU and GPU limits. At Low settings, the average FPS drops from 237 at 1080p to 163 at 1440p (a 31% reduction) and then to 96 at 4K (another 41% drop). This steep decline indicates that even at Low settings, the GPU becomes increasingly dominant as pixel count rises. The 1080p Low result of 237 FPS is likely near the CPU ceiling for Rust's simulation thread, as the RTX 5090 Mobile has far more rendering capacity than this number suggests.

At High settings, the scaling is more moderate: 134 FPS at 1080p, 92 FPS at 1440p (31% drop), and 54 FPS at 4K (41% drop from 1440p). The consistent percentage reductions across resolutions for each preset suggest that the GPU is the primary limiter throughout, with the CPU providing sufficient headroom even at 1080p. The Medium preset shows similar behavior: 159 to 109 to 65 FPS across the three resolutions, with the 4K result dropping 40% from the 1440p figure.

The Ultra preset tells a slightly different story. At 1080p, it delivers 102 FPS, which is only 24% lower than High at the same resolution. However, at 1440p, Ultra drops to 70 FPS (31% lower than High), and at 4K, it falls to 41 FPS (24% lower than High). The Ultra preset's larger absolute gaps suggest it imposes a heavier per-pixel cost, which the GPU absorbs less efficiently as resolution increases. The data indicates that Rust's Ultra settings introduce effects that scale super-linearly with pixel count, making 4K Ultra the most demanding configuration by a wide margin — 41 FPS versus 96 FPS at Low.

Measured FPS Breakdown

At 1920x1080, the Low preset achieves 237 FPS average, which is the highest recorded result across all settings and resolutions. Medium delivers 159 FPS with a range of 135 to 183 FPS, showing good consistency. High drops to 134 FPS, while Ultra bottoms out at 102 FPS. The 1080p results demonstrate that this combo can easily drive high-refresh-rate monitors at any quality level, with even the most demanding preset staying above 100 FPS.

Moving to 2560x1440, the Low preset still produces 163 FPS, which is a 31% reduction from the 1080p Low figure. Medium at 1440p averages 109 FPS, with min and max values of 93 and 126 FPS respectively. High at 1440p delivers 92 FPS, while Ultra falls to 70 FPS. The 1440p results remain playable across all settings, with the Medium preset offering a comfortable margin above 60 FPS.

At 3840x2160, the performance envelope tightens considerably. Low averages 96 FPS, Medium 65 FPS (with a range of 55 to 74 FPS), High 54 FPS, and Ultra 41 FPS. The 4K Medium result's minimum of 55 FPS is notable — it is the only recorded min FPS value that dips below 60 at any resolution, suggesting that 4K Medium is the threshold for maintaining a consistent 60 FPS experience. The Ultra preset at 4K, at 41 FPS, is the only configuration that falls below the 60 FPS threshold for smooth gameplay.

The data shows a consistent pattern: each step up in settings costs roughly 20-30% of frame rate, and each resolution increase from 1080p to 1440p to 4K costs another 30-40%. The combination of Ultra settings and 4K resolution compounds these penalties, resulting in the 41 FPS floor. The Medium preset's recorded min/max values provide the most reliable indicator of frame pacing consistency, with the 4K Medium range of 55-74 FPS showing acceptable stability for a survival game.

How This Combo Ranks

With a rank of 692 out of 3,723 tested combos, this system sits in the 81st percentile of all Rust configurations in the database. This places it ahead of the vast majority of tested hardware but behind the top-tier desktop setups that dominate the leaderboard. The GPU's percentile ranking of 84 among all GPUs and the CPU's 95th percentile ranking suggest that the combo's overall position is slightly held back by the GPU relative to the processor's strength.

Comparing to the nearest rivals provides context for the CPU's contribution. The AMD Ryzen AI Max+ 395's average benchmark score of 77,740 is 2% above the AMD Ryzen 9 8945HX (76,212), 1.6% above the AMD Ryzen Threadripper PRO 9945WX (76,513), and 1.6% above the AMD EPYC Embedded 8224P (76,492). The only rival it trails is the Intel Core i9-14900K, which scores 79,097 — a 1.7% advantage. These small deltas indicate that the CPU is competitive with high-end desktop parts despite its mobile form factor.

On the GPU side, the RTX 5090 Mobile's average benchmark score of 45,152 places it 0.8% above the RTX 4070 Ti (44,795), 0.5% below the AMD Radeon Pro 5500 XT (45,384), 1% below the Intel Arc A730M (45,592), and 1.8% below the RTX 5880 Ada Generation (45,972). The GPU's rank of 692 in Rust specifically suggests that the game is more demanding than the synthetic averages would imply, as the combo sits slightly lower than the GPU's raw percentile might predict.

The gap between the CPU's 95th percentile and the GPU's 84th percentile explains the observed performance scaling. At 1080p Low, the 237 FPS result likely approaches the CPU's limit for Rust's game logic and netcode processing. At 4K Ultra, the 41 FPS result shows the GPU becoming the dominant constraint. This balance means the combo's ranking would improve with lighter settings and worsen with heavier ones, which is consistent with the measured data.

Settings Recommendations

For 1920x1080 displays, the data supports using High settings as the default choice. The 134 FPS average at High is well above the 60 FPS threshold for smooth gameplay and only 19% lower than Medium's 159 FPS. The visual improvements from Medium to High come at a modest performance cost, making High the sweet spot for quality-conscious players. Ultra at 102 FPS remains playable and could be preferred for those who prioritize image fidelity over frame rate, especially on standard 60 Hz monitors.

For 2560x1440, Medium is the recommended starting point. The 109 FPS average with a 93 FPS minimum provides a comfortable buffer above 60 FPS, and the min/max range of 93-126 FPS indicates consistent frame delivery. High at 92 FPS is also viable, but the 16% drop from Medium makes Medium the safer choice for maintaining headroom during intense gameplay moments, such as large-scale raids or explosions. Ultra at 70 FPS is borderline — playable but with less margin for frame drops.

For 3840x2160, Low is the only preset that guarantees a high refresh rate experience at 96 FPS. Medium at 65 FPS, with a 55 FPS minimum, sits right at the edge of the 60 FPS threshold; players who accept occasional dips might find it acceptable, but the 55 FPS floor could cause noticeable stutter. High at 54 FPS and Ultra at 41 FPS are best reserved for slower-paced activities like building or resource gathering, where frame rate consistency matters less than visual quality.

Across all resolutions, the Low preset offers the largest performance margin and the most predictable frame delivery. However, the data suggests that Medium provides the best balance of visual quality and performance for most users, particularly at 1440p where the 109 FPS average with a 93 FPS minimum gives both smoothness and quality. For competitive play where maximum frame rate is critical, Low at 1440p (163 FPS) or 1080p (237 FPS) is the clear choice.

CPU Role

The AMD Ryzen AI Max+ 395 is a 16-core, 32-thread processor based on the Zen 5 architecture, codenamed Strix Halo. It operates at a base clock of 3.00 GHz and boosts up to 5.10 GHz, with a TDP of 55 W. The cache hierarchy includes 80 KB of L1 per core, 1 MB of L2 per core, and 64 MB of shared L3. The CPU supports LPDDR5X memory over a quad-channel interface, providing 256.0 GB/s of memory bandwidth. Its 4 nm process node from TSMC gives it a transistor density advantage that contributes to its 95th percentile ranking.

In Rust, the CPU's role is most visible at 1080p Low settings, where the 237 FPS result likely approaches the processor's limit for game logic updates and network synchronization. Rust is known for its server-side simulation and frequent entity updates, which create heavy single-thread load. The Ryzen AI Max+ 395's single-core performance, as measured by Cinebench R23 single-core score of 2,044 and Geekbench single-core of 2,464, provides the foundation for handling these serial workloads.

The multi-core strength of the CPU, demonstrated by a Cinebench R23 multi-core score of 35,314 and Geekbench multi-core of 20,992, helps with background tasks and the game's auxiliary threads. Rust's rendering thread can offload some work to additional cores, though the primary bottleneck remains the main simulation thread. The PassMark multithread score of 54,934 and physics score of 3,481 indicate robust parallel processing capability, which becomes relevant when many players are in close proximity, each with their own entity updates.

The CPU's nearest rivals in the benchmark database show how competitive this mobile processor is. The 2% lead over the AMD Ryzen 9 8945HX (76,212) is notable because that is also a high-end mobile chip. The 1.7% deficit to the Intel Core i9-14900K (79,097) is minor, and the CPU's 95th percentile placement means it outperforms 95% of all processors in the database. For Rust, this CPU is unlikely to be the limiting factor except at the lowest settings and resolutions, where the 237 FPS result at 1080p Low represents the practical ceiling of the game's engine rather than a hardware deficiency.
