Rust

The AMD Ryzen 5 8400F and AMD Radeon RX 9070 combination delivers a wide spread of performance in Rust, with the data showing that playability hinges almost entirely on resolution and the selected graphics preset. At 1920x1080, the pairing is overwhelmingly capable, while 2560x1440 remains very strong, and 3840x2160 requires a significant settings compromise to stay fluid. The measured FPS values below are the definitive guide, as no minimum or maximum frame data was recorded, making the average figures the sole basis for analysis.

Measured FPS Breakdown

The benchmark results for this CPU and GPU pairing in Rust show a clear and predictable scaling pattern across the three tested resolutions. At 1920x1080, the combo starts at an average of 214.3 FPS on Low settings, which is an exceptionally high figure that indicates a massive headroom for competitive play or high-refresh-rate monitors. Moving to Medium settings, the average drops to 143.1 FPS, still a very strong result that comfortably exceeds the 60 FPS playability threshold. High settings at 1080p produce an average of 121.5 FPS, demonstrating that even with increased visual fidelity, the frame rate remains far above what is required for smooth gameplay. The most demanding preset, Ultra, still yields an average of 93.4 FPS, which is a substantial drop from Low but remains firmly in the area of playable performance, with more than 30 FPS of headroom above the 60 FPS baseline.

At 2560x1440, the performance profile shifts downward, but the overall picture remains positive. Low settings at this resolution produce an average of 147.5 FPS, which is a significant reduction from the 1080p Low figure but still an excellent result for 1440p gaming. Medium settings average 99.3 FPS, again showing a clear step down from the 1080p result but retaining a comfortable margin over the playability threshold. High settings at 1440p average 83.4 FPS, which is still a strong performance level, and the most demanding Ultra preset manages an average of 64.7 FPS. This final figure is notable because it just clears the 60 FPS mark, indicating that Ultra settings are technically playable at this resolution, though with less margin for error in demanding scenes.

The 3840x2160 resolution tells a different story, as the demands of 4K rendering significantly tax the GPU. Low settings at 4K average 85.5 FPS, which is still a very playable result and shows the raw power of the RX 9070. However, Medium settings drop the average to 57.6 FPS, which falls below the 60 FPS playability threshold. High settings average 48.7 FPS, and the Ultra preset manages only 35.3 FPS. The scaling from Low to Ultra at 4K is steep, with the Ultra preset delivering less than half the frame rate of Low. This data clearly indicates that 4K resolution requires careful settings management, as only the Low preset provides a consistently playable experience, while every other preset falls short of the 60 FPS target.

Similar Performance Alternatives

The benchmark database provides nearest rival data for both the CPU and GPU, which helps contextualize this combo’s expected behavior. For the AMD Ryzen 5 8400F, the closest comparable processors are all within a very narrow performance band. The AMD Ryzen 5 7500F is the direct competitor, with an average benchmark score of 24964, which is a delta of 0.2% from the 8400F’s score of 25005. This means the two CPUs are effectively identical in synthetic workloads, so users could expect nearly the same frame rates in Rust. The Intel Core i7-11850H has an average score of 24935, a delta of 0.3%, placing it in the same performance tier. Similarly, the Intel Core i7-13620H scores 24911, a delta of 0.4%, and the AMD EPYC 9474F scores 25103, a delta of -0.4%. All four rivals sit within a 0.8% range of the 8400F, so any of these CPUs would produce remarkably similar results when paired with the same GPU.

On the GPU side, the AMD Radeon RX 9070’s nearest rivals show a wider spread of potential alternatives. The NVIDIA GeForce GTX TITAN Z has an average score of 23736, which is a delta of 0.6% from the RX 9070’s average of 23877. This is a surprising result given the age of the TITAN Z, but the data places it in a similar performance class. The AMD Radeon RX 6800S scores 24063, a delta of -0.8%, meaning it is slightly faster in synthetic benchmarks. The NVIDIA GeForce RTX 3080 Mobile scores 23628, a delta of 1.1%, and the NVIDIA GeForce RTX 2080 SUPER scores 24170, a delta of -1.2%. These four GPUs all fall within a 2.3% performance range of the RX 9070, suggesting that any of them would deliver similar frame rates in Rust. For a builder looking at alternatives, swapping the RX 9070 for an RTX 2080 SUPER would likely result in nearly identical gameplay performance, while the RX 6800S might offer a marginal improvement.

How This Combo Ranks

In the broader context of all tested hardware combinations, this pairing of the AMD Ryzen 5 8400F and AMD Radeon RX 9070 holds a rank of 1043 out of 3723 total combos in the Rust benchmark database. This places the combo in the top 28% of all tested systems, which is a solid position given the wide variety of hardware configurations that have been evaluated. The rank reflects the balanced nature of this pairing, where the CPU’s mid-range performance and the GPU’s high-end capabilities combine to produce results that are better than the majority of systems but not at the very top tier. The 8400F’s percentile rank against all CPUs is 77, meaning it outperforms 77% of processors in the database, while the RX 9070’s percentile rank against all GPUs is 69, outperforming 69% of graphics cards. The combo’s overall rank of 1043 out of 3723 suggests that while each component is individually strong, the pairing does not push into the top echelon of systems, likely due to the CPU being a slight bottleneck at lower resolutions where the GPU’s full potential is more difficult to realize.

The data indicates that this combo is well-suited for high-refresh-rate gaming at 1080p and solid 1440p performance, but it is not a top-tier 4K machine. The rank also implies that there is room for improvement by pairing the RX 9070 with a stronger CPU, which would likely boost the combo’s standing in the database. However, for the specific goal of playing Rust, the current ranking is more than adequate, as the measured FPS figures show that the combo clears the 60 FPS threshold at all tested settings for 1080p and 1440p.

The Verdict

The verdict on whether this PC can run Rust is a qualified yes, with the qualification being resolution-dependent. According to the verdict by resolution data, at 1920x1080, all four tested presets—Low, Medium, High, and Ultra—are considered playable, with the best settings being Ultra at an average of 93.4 FPS. This means that a user can enjoy the game at maximum visual quality at 1080p with a frame rate that is well above the 60 FPS playable threshold. At 2560x1440, the same four presets are all playable, with Ultra again being the best option at an average of 64.7 FPS. This is a tighter margin, but it still clears the 60 FPS line, so the game remains fully playable at 1440p with all settings maxed out.

At 3840x2160, the situation changes dramatically. Only the Low preset is considered playable, with an average of 85.5 FPS, which is a solid result for 4K gaming. The Medium preset at 57.6 FPS, High at 48.7 FPS, and Ultra at 35.3 FPS all fall below the 60 FPS threshold, making them not playable according to the benchmark criteria. This means that for 4K gaming, the user must sacrifice visual quality and run the game on Low settings to achieve a consistently smooth experience. The overall verdict is that this PC can run Rust exceptionally well at 1080p and 1440p, but at 4K, it is limited to low visual fidelity to maintain playability.

CPU and GPU Roles

Understanding which component matters more for Rust at each resolution requires examining the scaling between the different settings and resolutions in the measured FPS data. The CPU, an AMD Ryzen 5 8400F with 6 cores and 12 threads, has a boost clock of 4.70 GHz and a Cinebench R23 multicore score of 20851. The GPU, an AMD Radeon RX 9070 with 3584 shading units and 16 GB of GDDR6 memory, has a boost clock of 2520 MHz and a Passmark G3D score of 25381. In Rust, which is known for its CPU-heavy simulation and physics, the balance between these two components shifts as resolution changes.

At 1920x1080, the frame rates are exceptionally high, with Low settings hitting 214.3 FPS and Ultra at 93.4 FPS. The fact that the Low preset nearly doubles the Ultra preset’s frame rate suggests that the GPU is handling the resolution and texture load, while the CPU is managing the game’s simulation. At lower resolutions, the GPU has less pixel work to do, which means the CPU becomes more of a limiting factor. The 8400F’s single-thread performance, as indicated by its Cinebench R23 single-core score of 2943, is sufficient to push these high frame rates, but the gap between Low and Ultra at 1080p is substantial, indicating that the GPU’s workload increases significantly with higher settings.

At 2560x1440, the frame rates drop across all settings, with Low at 147.5 FPS and Ultra at 64.7 FPS. The reduction from 1080p to 1440p is roughly 25-30% across the board, which is a typical scaling for GPU-bound workloads. This suggests that the GPU is starting to become the primary bottleneck at this resolution, as the CPU has more time to prepare frames while the GPU renders the higher pixel count. The fact that Ultra settings still clear 60 FPS indicates that the RX 9070 has enough headroom to handle 1440p with maxed-out visuals, but the margin is thinner than at 1080p.

At 3840x2160, the GPU is clearly the dominant factor. The frame rates plummet to 85.5 FPS on Low and 35.3 FPS on Ultra, which is a reduction of over 50% from the 1080p figures. This massive drop is a classic sign of a GPU-bound scenario, where the RX 9070’s 644.6 GB/s of memory bandwidth and 36.13 TFLOPS of FP32 performance are strained by the 4K pixel load. The CPU’s role becomes less critical at this resolution, as the GPU is unable to render frames fast enough for the CPU to become a limiting factor. The data shows that the 8400F’s performance is more than adequate for Rust at 4K, as the bottleneck is entirely on the GPU side.

Best Settings per Resolution

Based on the measured FPS data and the verdict by resolution, the best settings for each resolution are defined as the most demanding preset that maintains an average frame rate at or above 60 FPS. At 1920x1080, the Ultra preset is the clear winner, with an average of 93.4 FPS. This is the highest visual quality available, and it still provides a frame rate that is more than 30 FPS above the playability threshold. There is no reason to lower settings at 1080p, as the combo has ample headroom to run the game at maximum fidelity.

At 2560x1440, the Ultra preset also qualifies as the best setting, with an average of 64.7 FPS. This is a tighter margin, only 4.7 FPS above the 60 FPS threshold, but it still clears the bar. Users who prioritize a more consistent frame rate might consider dropping to High settings at 83.4 FPS for additional safety, but the data shows that Ultra is technically playable at 1440p. The choice between High and Ultra at this resolution depends on whether the user prefers maximum visual quality or a larger frame rate buffer.

At 3840x2160, the situation is more restrictive. The only preset that achieves an average of 60 FPS or higher is Low, with an average of 85.5 FPS. This is the best setting for 4K, as it is the most demanding preset that remains playable. The Medium preset at 57.6 FPS falls just short of the threshold, so it is not recommended for a consistently smooth experience. The data indicates that to play Rust at 4K with this combo, the user must accept Low settings, which sacrifices significant visual detail but still delivers a highly playable frame rate. For users who are unwilling to compromise on visual quality, 2560x1440 with Ultra settings is the optimal choice, as it provides a much better balance of fidelity and performance.
