Rust

The AMD Ryzen AI Max+ 395 paired with the NVIDIA GeForce RTX 5070 Ti Mobile delivers a wide spread of frame rates in Rust, depending on resolution and preset. At 1920x1080, the combo ranges from 82 FPS on Ultra to 189 FPS on Low, while at 3840x2160, the same settings span 33 FPS to 77 FPS. The data indicates that this system is capable of high refresh rates at lower resolutions but becomes progressively more constrained as pixel count rises. This analysis walks through the measured results, the role of each component, and what the numbers imply for practical use.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial across all settings. At Low settings, the average frame rate falls from 189 FPS at 1920x1080 to 130 FPS at 2560x1440, then to 77 FPS at 3840x2160. That is a 59% reduction from 1080p to 4K. At High settings, the progression is 107 FPS at 1080p, 74 FPS at 1440p, and 44 FPS at 4K — a 59% drop as well, though the absolute numbers are lower. Medium settings show 127 FPS at 1080p, 87 FPS at 1440p, and 52 FPS at 4K, which is a 59% decline. Ultra settings start at 82 FPS at 1080p, fall to 56 FPS at 1440p, and end at 33 FPS at 4K, a 60% reduction.

The consistency of these percentage drops—hovering around 59-60% from 1080p to 4K—suggests that the scaling is primarily driven by pixel throughput. The RTX 5070 Ti Mobile, with its 12 GB of GDDR7 memory and 192-bit bus, sees its workload roughly quadruple in pixel count when moving from 1080p to 4K, and the frame rate responds nearly linearly to that increase. The fact that the drop is not perfectly 75% (which would be the case if the GPU were fully saturated) indicates that other factors, such as CPU overhead or memory bandwidth, are also in play.

At 1440p, the scaling is gentler. From 1080p to 1440p, the pixel count increases by 78%, but the frame rate drops by only 31% at Low (189 to 130), 31% at High (107 to 74), 31% at Medium (127 to 87), and 32% at Ultra (82 to 56). This less-than-proportional drop suggests that at 1080p, the system is not fully GPU-limited; the CPU is likely contributing to the ceiling. The Ryzen AI Max+ 395, with its 16 cores and 32 threads, has strong multi-threaded performance, but Rust's single-threaded nature may limit how much of that headroom translates into higher FPS at low resolutions.

The limiting component shifts clearly as resolution rises. At 1080p, the gap between Low and Ultra is 107 FPS (189 vs 82), which is a 130% difference. At 4K, the gap narrows to 44 FPS (77 vs 33), a 133% difference in relative terms but a smaller absolute spread. This narrowing in absolute terms indicates that at 4K, the GPU is the bottleneck; increasing settings from Low to Ultra costs more performance because the GPU is already stretched thin by the pixel count. At 1080p, the CPU can still feed the GPU enough to make settings matter more, but even then, the Ultra preset at 82 FPS shows the GPU is not the sole constraint.

Data from the measured rows shows that the min FPS at Medium settings tracks closely with the average FPS of the next lower resolution. For instance, at 3840x2160 Medium, the min FPS is 44, which matches the average FPS at 4K High. At 2560x1440 Medium, the min FPS is 74, which equals the average at 1440p High. This pattern suggests that frame time consistency degrades with resolution, and the variance between min and max FPS grows from 38 FPS at 1080p Medium (108 to 146) to 15 FPS at 4K Medium (44 to 59). The smaller variance at 4K is expected because the GPU is more uniformly busy, but the absolute min FPS values are low enough to affect gameplay smoothness.

FAQ

Q: What is the highest average FPS this combo achieves in Rust?

A: The highest measured average is 189 FPS at 1920x1080 with Low settings. The next fastest is 130 FPS at 2560x1440 with Low settings, followed by 127 FPS at 1080p Medium.

Q: Can this system maintain 60 FPS at 4K in Rust?

A: No. The only 4K result above 60 FPS is Low settings at 77 FPS. Medium averages 52 FPS, High averages 44 FPS, and Ultra averages 33 FPS. At 4K, the GPU is the limiting factor, and even Low settings only provide a 17 FPS margin above 60.

Q: How does the Ultra preset compare to High at the same resolution?

A: At every resolution, Ultra is significantly slower than High. At 1080p, Ultra averages 82 FPS versus High’s 107 FPS, a 23% reduction. At 1440p, Ultra averages 56 FPS versus High’s 74 FPS, a 24% reduction. At 4K, Ultra averages 33 FPS versus High’s 44 FPS, a 25% reduction.

Q: Which resolution provides the best balance of FPS and visual quality based on the data?

A: 2560x1440 with High settings appears optimal, averaging 74 FPS. That is above 60 FPS and offers a resolution improvement over 1080p. The 1440p Medium preset averages 87 FPS, which is also smooth, but High adds visual detail without dropping below 74 FPS.

Q: Is the CPU or GPU more responsible for the FPS differences between settings?

A: The data suggests the GPU dominates at higher resolutions. At 4K, the FPS difference between Low and Ultra is 44 FPS (77 vs 33), while at 1080p, it is 107 FPS (189 vs 82). The larger absolute gap at 1080p implies that the CPU allows the GPU to work harder at lower resolutions, but the GPU still dictates the ceiling at 4K.

Q: What is the minimum FPS recorded in the measured data?

A: The lowest min FPS is 44, observed at 3840x2160 with Medium settings. The same min FPS value appears at 2560x1440 with Medium settings. At 1080p Medium, the min FPS is 108.

GPU Role

The NVIDIA GeForce RTX 5070 Ti Mobile is a Blackwell 2.0 architecture part built on a 5 nm process from TSMC, with 31,100 million transistors on a 263 mm² die. It has 12 GB of GDDR7 memory on a 192-bit bus, yielding a memory bandwidth of 672.0 GB/s. The base clock is 847 MHz, and the boost clock reaches 1447 MHz, with memory running at 1750 MHz (28 Gbps effective). The GPU has 5888 shading units, 184 texture mapping units, and 80 ROPs, along with 46 ray tracing cores and 184 tensor cores. Its FP32 performance is 17.04 TFLOPS, and the texture rate is 266.2 GTexel/s.

In Rust, the GPU’s role becomes more pronounced as resolution increases. At 1080p, the average FPS across all settings is 126 (189, 127, 107, 82 for Low, Medium, High, Ultra respectively). At 1440p, the average drops to 87 (130, 87, 74, 56). At 4K, the average is 52 (77, 52, 44, 33). The RTX 5070 Ti Mobile’s memory bandwidth of 672.0 GB/s is likely a key factor at 4K, where the 12 GB frame buffer is under heavy load. Rust’s large open-world environments and frequent texture streaming benefit from the GDDR7 memory, but the 192-bit bus width limits the total bandwidth compared to wider-bus alternatives.

The boost clock of 1447 MHz is modest for a mobile GPU, and the 60 W TDP suggests this is a power-constrained implementation. The data indicates that at 4K Ultra, the GPU is fully saturated, averaging only 33 FPS. At 1080p Low, the GPU is not the bottleneck, as the 189 FPS result is likely near the CPU’s limit for Rust’s single-threaded performance. The passmark G3D score of 24004 places this GPU in the 80th percentile of all GPUs, with nearest rivals including the NVIDIA Quadro GV100 (-0.2% delta) and the AMD Radeon Pro Duo (-1.2% delta). This relative positioning suggests that the RTX 5070 Ti Mobile is a mid-to-high-tier mobile GPU, but not a top-tier desktop replacement.

The VRAM size of 12 GB is sufficient for Rust at 1080p and 1440p, where the measured FPS does not show signs of memory capacity throttling. At 4K, the frame rates are low but consistent with GPU compute limits rather than VRAM overflow. The FP32 performance of 17.04 TFLOPS translates to a pixel rate of 115.8 GPixel/s, which aligns with the observed 4K performance: at 33 FPS Ultra, the GPU is processing roughly 33 frames per second times 8.3 million pixels, which is near the pixel rate ceiling.

Settings Recommendations

Based on the measured rows, the best experience depends on the target resolution. For 1920x1080, the High preset at 107 FPS provides a smooth experience with visual fidelity above the Low baseline. The Medium preset at 127 FPS is slightly faster but offers reduced detail; the 20 FPS difference between Medium and High may be worth the visual trade-off for most users. The Ultra preset at 82 FPS is still playable but represents a 23% drop from High, which is a significant cost for marginal visual gains.

At 2560x1440, the High preset at 74 FPS is the recommended choice. It stays above the 60 FPS threshold with a 14 FPS margin. Medium at 87 FPS is also viable and provides more headroom for dips, as the min FPS at Medium is 74. The Ultra preset at 56 FPS falls below 60, making it less desirable for fast-paced gameplay. Low at 130 FPS is possible for competitive play, but the visual quality reduction is substantial.

For 3840x2160, the data shows that no preset averages above 77 FPS. The Low preset at 77 FPS is the only option that clears 60 FPS, but it comes with the lowest visual settings. Medium at 52 FPS and High at 44 FPS are playable for slower, exploration-focused sessions, but they may suffer from frame pacing issues, as the min FPS at Medium is 44. Ultra at 33 FPS is borderline unplayable for most users. Given that Rust is a survival game with PvP elements, frame rate consistency matters. The 1440p High preset offers the best compromise: 74 FPS average, a resolution that is visually sharp, and settings that still show environmental detail.

Measured FPS Breakdown

At 1920x1080, the measured averages are as follows: Low settings achieve 189 FPS, Medium achieves 127 FPS with a min of 108 and a max of 146, High achieves 107 FPS, and Ultra achieves 82 FPS. The spread from Low to Ultra is 107 FPS, and the Medium preset shows a variance of 38 FPS between min and max.

At 2560x1440, Low settings average 130 FPS, Medium averages 87 FPS with a min of 74 and a max of 101, High averages 74 FPS, and Ultra averages 56 FPS. The spread from Low to Ultra is 74 FPS, and the Medium variance is 27 FPS.

At 3840x2160, Low settings average 77 FPS, Medium averages 52 FPS with a min of 44 and a max of 59, High averages 44 FPS, and Ultra averages 33 FPS. The spread from Low to Ultra is 44 FPS, and the Medium variance is 15 FPS.

The data shows a consistent pattern: lowering settings from Ultra to Low provides a larger absolute FPS gain at lower resolutions. At 1080p, the gain from Ultra to Low is 107 FPS, which is a 130% increase. At 1440p, the gain is 74 FPS, a 132% increase. At 4K, the gain is 44 FPS, a 133% increase. This means that the relative benefit of Low over Ultra is nearly identical across resolutions, but the absolute headroom is greatest at 1080p.

The Medium preset is the only one with min and max values recorded. Across all three resolutions, the min FPS at Medium is consistently 15-20% below the average: at 1080p, min is 108 vs average 127 (15% lower); at 1440p, min is 74 vs average 87 (15% lower); at 4K, min is 44 vs average 52 (15% lower). This consistency suggests that Medium settings produce predictable frame time variance, which can be useful for planning a target FPS floor.

CPU Role

The AMD Ryzen AI Max+ 395 is a 16-core, 32-thread processor based on Zen 5 architecture (Strix Halo) with a base clock of 3.00 GHz and a boost clock of 5.10 GHz. It has a 64 MB shared L3 cache, 80 KB L1 per core, and 1 MB L2 per core. The CPU supports LPDDR5X memory in a quad-channel configuration, providing 256.0 GB/s of memory bandwidth. Its TDP is 55 W, and it is built on a 4 nm process from TSMC.

In Rust, the CPU’s role is most evident at lower resolutions. At 1080p Low, the system achieves 189 FPS, which is likely near the CPU’s single-thread limit for this game. The Ryzen AI Max+ 395 has a strong single-core score of 2044 in Cinebench R23, which places it in the 95th percentile of all CPUs. Its nearest rivals include the Intel Core i9-14900K (-1.7% delta) and the AMD Ryzen 9 8945HX (2% delta). This puts the Ryzen AI Max+ 395 slightly above the Core i9-14900K in average benchmark score, but the delta is small.

The 16 cores and 32 threads are not fully utilized by Rust, which is known to be lightly threaded. However, the high boost clock of 5.10 GHz helps with the game’s primary thread, and the 64 MB L3 cache reduces memory latency for frequently accessed data. The passmark single-thread score of 4147 is strong, and the multithread score of 54934 indicates that the CPU can handle background tasks while gaming.

At 4K, the CPU’s influence diminishes. The FPS at 4K is 44-77 depending on settings, and the GPU is clearly the bottleneck. The memory bandwidth of 256.0 GB/s from the CPU is sufficient to feed the GPU without causing stutter, as the min FPS values at Medium settings do not show large dips. The CPU’s 55 W TDP is low for a 16-core part, but the 4 nm process node keeps thermals manageable, allowing sustained boost clocks during gaming sessions.

The benchmark data shows that the Ryzen AI Max+ 395 outperforms the AMD Ryzen 9 8945HX by 2% and the AMD Ryzen Threadripper PRO 9945WX by 1.6%, but trails the Intel Core i9-14900K by 1.7%. This places it in the upper echelon of mobile CPUs, though the differences are marginal. For Rust, the single-thread performance is the critical metric, and the 5.10 GHz boost clock provides a solid foundation for the 189 FPS result at 1080p Low.

How This Combo Ranks

The combo of the AMD Ryzen AI Max+ 395 and the NVIDIA GeForce RTX 5070 Ti Mobile ranks 1412 out of 3723 tested combinations in Rust. This places it in the 62nd percentile of all combos, meaning it outperforms more than half of the tested systems but is not in the top tier. The rank reflects the balance between the CPU’s strong single-thread performance and the GPU’s mid-range mobile capabilities.

The GPU’s percentile of 80 and the CPU’s percentile of 95 indicate that the CPU is relatively stronger than the GPU. This imbalance is visible in the measured FPS: at 1080p, the system can reach 189 FPS, which is high, but at 4K, it drops to 33 FPS on Ultra, which is low. The GPU is the limiting factor at higher resolutions, pulling the overall rank down despite the CPU’s excellent showing.

The combo’s rank of 1412 out of 3723 suggests that there are many systems with faster GPUs that achieve higher FPS in Rust at 4K. However, the data also shows that the CPU is not holding the GPU back at lower resolutions, as evidenced by the 189 FPS result. For a mobile platform, this combo offers a good balance for 1080p and 1440p gaming, but it is not designed for 4K Ultra settings.

The nearest rival GPUs, such as the NVIDIA Quadro GV100 (-0.2% delta) and the AMD Radeon Pro Duo (-1.2% delta), have similar average benchmark scores, but their performance in Rust specifically may differ due to driver optimizations and VRAM configurations. The RTX 5070 Ti Mobile’s 12 GB of GDDR7 memory is a differentiator, but the data does not show a clear advantage over these rivals in the measured FPS, as those rivals are not part of the same combo rankings.

Overall, the rank of 1412 out of 3723 indicates that this combo is above average but not exceptional. Users seeking higher FPS at 4K would need a more powerful GPU, while those prioritizing 1080p performance will find this combo capable of exceeding 100 FPS on most settings. The CPU’s high percentile ensures that future GPU upgrades would not be bottlenecked at lower resolutions, making this a versatile platform for Rust.
