Rust

The AMD Ryzen 9 8945HX paired with the NVIDIA GeForce RTX 5070 Ti delivers a wide spread of frame rates in Rust, ranging from 33 FPS at 4K Ultra to 189 FPS at 1080p Low. This combination ranks 1043rd out of 2953 tested combos in the database, placing it in the upper third of all configurations. The measured data shows a system that scales predictably with resolution and settings, though the pattern of results reveals where the bottleneck shifts as workload changes.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent across all settings presets. At Low settings, the average frame rate falls from 189 FPS at 1920x1080 to 130 FPS at 2560x1440, then further to 77 FPS at 3840x2160. That represents a 31% reduction moving from 1080p to 1440p, and another 41% reduction moving from 1440p to 4K. The total decline from 1080p Low to 4K Low is 59%, which indicates that the GPU is becoming progressively more stressed as pixel count rises.

At High settings, the pattern is similar but with lower absolute numbers. The average drops from 107 FPS at 1080p to 74 FPS at 1440p, then to 44 FPS at 4K. The percentage declines are 31% and 41% respectively, nearly identical to the Low preset. This consistency suggests that resolution scaling in Rust follows a predictable curve regardless of the quality preset, with the GPU handling the additional pixel workload in a linear fashion.

Medium settings show the same trajectory: 127 FPS at 1080p, 87 FPS at 1440p, and 52 FPS at 4K. The min FPS values at Medium are also recorded, providing insight into frame time consistency. At 1080p Medium, the minimum is 108 FPS against an average of 127, giving a spread of 19 FPS. At 1440p Medium, the minimum is 74 FPS against an average of 87, a spread of 13 FPS. At 4K Medium, the minimum is 44 FPS against an average of 52, a spread of 8 FPS. The narrowing spread at higher resolutions indicates that the GPU is working more uniformly under heavier load, whereas at lower resolutions, CPU or other system limits may introduce more variability.

Ultra settings produce the lowest frame rates across the board: 82 FPS at 1080p, 56 FPS at 1440p, and 33 FPS at 4K. The 1080p to 1440p drop is 32%, and the 1440p to 4K drop is 41%. Even at 1080p Ultra, the average of 82 FPS is below the 107 FPS achieved at High settings, showing that the Ultra preset carries a significant performance cost. The 4K Ultra result of 33 FPS is the only measured value that falls below the 30 FPS threshold, making it marginal for playable frame rates.

The scaling pattern strongly suggests that the RTX 5070 Ti becomes the limiting factor at 4K across all settings. At 1080p, the frame rates range from 82 to 189 FPS, which implies that the CPU is able to feed the GPU adequately at lower resolutions. However, the consistent 41% drop from 1440p to 4K across all presets points to the GPU hitting its rendering ceiling as pixel count increases. The 16 GB of GDDR7 memory and 256-bit bus provide 896.0 GB/s of bandwidth, which should be sufficient for Rust's texture loads, yet the raw compute demand at 4K overwhelms the GPU's 43.94 TFLOPS of FP32 performance.

Settings Recommendations

The measured data provides clear guidance on which preset offers the best balance. At 1080p, Medium settings deliver 127 FPS average with a minimum of 108 FPS, which is comfortably above the 60 FPS threshold for smooth gameplay. High settings at 1080p drop to 107 FPS average, still respectable but 20 FPS lower than Medium. Ultra at 1080p falls to 82 FPS, which is playable but represents a 35% reduction from Medium. Low at 1080p hits 189 FPS, but the visual quality trade-off is substantial for a survival game where visibility matters.

At 1440p, Medium settings produce 87 FPS average with a minimum of 74 FPS. This is the recommended preset for this resolution, as it stays above 60 FPS even in the worst-case measured frame. High at 1440p averages 74 FPS, which is still playable but leaves less headroom for demanding scenes. Low at 1440p averages 130 FPS, but again sacrifices visual fidelity. Ultra at 1440p averages 56 FPS, dipping below the 60 FPS threshold, which makes it less desirable for consistent performance.

At 4K, the situation becomes more constrained. Medium settings average 52 FPS with a minimum of 44 FPS, which is the only preset that stays above 30 FPS in both average and minimum metrics. High at 4K averages 44 FPS, while Low averages 77 FPS. Ultra at 4K averages 33 FPS, which is technically above 30 FPS but leaves almost no margin for frame drops during intense gameplay. The data suggests that Medium is the highest preset that maintains a playable experience at 4K, while Low provides a smoother experience if frame rate is prioritized over visual quality.

Comparing the presets across resolutions, Medium consistently offers the best performance-to-quality ratio. At every resolution, Medium maintains a minimum FPS that is at least 65% of the average FPS, indicating stable frame delivery. High settings at 4K drop to 44 FPS average, which is below the 52 FPS achieved at Medium, and the gap widens as resolution increases. The Ultra preset is only viable at 1080p, where it still achieves 82 FPS, but at 1440p and 4K it falls below the 60 FPS and 40 FPS marks respectively.

GPU Role

The NVIDIA GeForce RTX 5070 Ti is the primary driver of the frame rates measured in this dataset. Its 16 GB of GDDR7 memory on a 256-bit bus provides 896.0 GB/s of bandwidth, which directly influences how quickly textures and geometry can be streamed to the rendering pipeline. In Rust, which features large open-world environments with dynamic building mechanics, memory bandwidth is critical for maintaining consistent frame times. The 896.0 GB/s figure is the key specification here, as it allows the GPU to handle the game's asset streaming without becoming a bottleneck at lower resolutions.

The GPU's clock speeds are 2295 MHz base and 2452 MHz boost. These clocks, combined with the 8960 shading units, determine the raw compute throughput of 43.94 TFLOPS FP32. At 1080p, the GPU is not fully utilized, as evidenced by the 189 FPS at Low settings. The fact that frame rates at 1080p are higher than at 1440p or 4K indicates that the GPU has spare capacity at lower pixel counts, and the limiting factor shifts to the CPU or other system components. However, at 4K, the GPU is clearly the bottleneck, with all presets showing substantial frame rate drops that correlate with the increased pixel workload.

The 70 RT cores and 280 tensor cores are present in the architecture, though Rust does not heavily utilize ray tracing or DLSS features in the measured data. The benchmark results for the GPU show a Passmark G3D score of 32974 and a 3DMark Steel Nomad DX12 score of 6604, placing the GPU at the 86th percentile of all GPUs. The nearest rivals in the database include the AMD Radeon RX 6900 XT with an average score of 50951 (2% higher), the AMD Radeon RX 6800 XT at 48477 (3.1% lower), and the Intel Arc A550M at 49737 (0.4% higher). These comparisons show that the RTX 5070 Ti sits in a competitive position, though its percentile rank of 86 indicates that it is not at the very top of the GPU hierarchy.

The GPU's 300 W TDP and 700 W suggested PSU requirement are notable for system planning, but the measured FPS data is what matters for gameplay. The 4K results, in particular, show that the GPU's 43.94 TFLOPS is insufficient to maintain high frame rates at Ultra settings, where the average drops to 33 FPS. The 16 GB memory capacity is adequate for Rust's texture requirements, as evidenced by the fact that frame rates do not collapse due to memory swapping, but the compute throughput limits performance at higher resolutions and settings.

How This Combo Ranks

The AMD Ryzen 9 8945HX and NVIDIA GeForce RTX 5070 Ti combination ranks 1043rd out of 2953 tested combos in Rust, placing it in the 65th percentile of all configurations. This rank indicates that while the combo performs above average, there are 1042 other combinations that achieve higher frame rates in this specific game. The ranking is based on measured FPS data across all resolutions and settings, suggesting that the combo's performance is solid but not exceptional for Rust's requirements.

The CPU's benchmark scores provide context for this ranking. The Ryzen 9 8945HX achieves a Cinebench R23 multicore score of 42713 and a single-core score of 6030. Its average benchmark score is 76212, which places it at the 95th percentile of all CPUs. The nearest CPU rivals include the Intel Core Ultra 9 285HX with an average score of 76155 (0.1% higher), the AMD EPYC Embedded 8224P at 76492 (0.4% lower), the AMD Ryzen Threadripper PRO 9945WX at 76513 (0.4% lower), and the AMD Ryzen 9 9950X3D at 75779 (0.6% higher). These scores indicate that the CPU is highly capable, but the combo's rank of 1043 suggests that the GPU is the limiting factor in Rust.

The combo rank relative to the CPU's 95th percentile and GPU's 86th percentile shows a slight mismatch. The CPU is more powerful relative to other CPUs than the GPU is relative to other GPUs. This means that in Rust, which is known to be CPU-intensive in certain scenarios, the combo might not fully utilize the CPU's potential because the GPU constrains overall frame rates. The fact that the combo ranks in the 65th percentile of all combos, while the CPU ranks in the 95th percentile and the GPU in the 86th percentile, suggests that the combination is not perfectly balanced for this game. A stronger GPU would likely push the combo higher in the rankings, given the CPU's headroom.

CPU Role

The AMD Ryzen 9 8945HX is a 16-core, 32-thread processor based on the Zen 4 architecture with a Dragon Range codename. Its base clock is 2.50 GHz and boost clock is 5.40 GHz, with a 55 W TDP. The CPU's L3 cache is 64 MB, which is substantial for gaming workloads. In the benchmark data, the CPU shows strong multi-threaded performance with a Cinebench R23 multicore score of 42713, but its single-core score of 6030 is also competitive.

In Rust, the CPU's role is primarily in handling game logic, physics, and entity management. The 16 cores and 32 threads provide ample parallel processing capability, which is reflected in the Passmark multithread score of 51405 and the Passmark physics score of 2168. The CPU's 5.40 GHz boost clock is beneficial for single-threaded tasks, which Rust relies on for its main game loop. The 64 MB L3 cache helps reduce memory latency, improving frame time consistency in scenarios with many entities.

The measured FPS data shows that the CPU is not the primary bottleneck at 1080p. The fact that Low settings achieve 189 FPS at 1080p indicates that the CPU can feed the GPU with enough frames to reach high frame rates. However, the drop from 189 FPS at 1080p Low to 130 FPS at 1440p Low, and then to 77 FPS at 4K Low, demonstrates that the GPU becomes the limiting factor as resolution increases. At 1080p, the CPU has headroom, as evidenced by the fact that increasing settings from Low to Medium only drops the frame rate from 189 to 127 FPS, while increasing to Ultra drops it to 82 FPS. This suggests that the GPU is handling the additional visual workload at 1080p, rather than the CPU being saturated.

The CPU's 95th percentile ranking against all CPUs, combined with its nearest rivals all being within 0.6% of its average score, indicates that it is among the top processors available. In Rust, the CPU's multi-threading capabilities are likely well-utilized in busy servers with many players and structures, but the measured data does not show a scenario where the CPU limits performance below what the GPU can deliver. The 32 threads provide enough parallelism for Rust's server-side simulation, but the client-side rendering is GPU-bound in most of the measured presets.
