Rust

The AMD Ryzen 9 9900X3D and NVIDIA GeForce RTX 4070 combination ranks 810th out of 3,723 tested combos in Rust. This places the pairing in the top 22% of all systems, a strong position for a game that often struggles with CPU-heavy server logic. The ranking shows the combo is capable, but the RTX 4070 is the limiting factor at higher resolutions, while the 9900X3D ensures the frame rate stays high when the GPU can keep up.

How This Combo Ranks

The combo’s rank of 810 out of 3,723 is solidly above the median. The data shows this is not an extreme enthusiast setup, but it is far from a low-end pairing. The percentile position suggests the 9900X3D’s 3D V-Cache and 12 cores are doing heavy lifting in Rust’s simulation-heavy moments, while the RTX 4070’s 12 GB of GDDR6X memory is sufficient for the game’s demands at most settings.

When looking at the CPU’s standalone performance, the Ryzen 9 9900X3D scores 54,762 on average, which places it in the 91st percentile of all CPUs. Its nearest rival, the Intel Core Ultra 5 245KF, scores 55,093, a negligible 0.6% difference. The 9900X3D is also within 2.1% of the Intel Core i7-14700F (53,620) and 1.3% of the Core Ultra 5 245K (54,053). This means the CPU is not the bottleneck in most scenarios; the game will leverage its 24 threads and 128 MB of L3 cache for sorting, physics, and entity updates.

The GPU, meanwhile, is in the 81st percentile of all GPUs with an average benchmark score of 37,648. Its closest rival, the NVIDIA Tesla P4, scores 37,628, a mere 0.1% difference, which is effectively a tie. The AMD Radeon RX Vega 56 scores 37,507, 0.4% behind, and the RTX 4080 Mobile scores 38,135, 1.3% ahead. This cluster of scores tells a clear story: the RTX 4070 is a solid mid-range performer, but it will not deliver extreme frame rates in Rust at 4K Ultra.

The measured FPS data confirms this. At 3840x2160, the combo hits 52 FPS on High and 39 FPS on Ultra, which are below the 60 FPS playable threshold. The rank of 810 reflects this ceiling. The combination is clearly a 1440p and 1080p champion, not a 4K one.

CPU and GPU Roles

The data reveals a shifting balance of responsibility between the CPU and GPU as resolution changes. At 1920x1080, the CPU dominates. The average FPS jumps from 127 on High to 225 on Low, a 77% increase. This is typical of a CPU-bound scenario where reducing graphical load lets the 9900X3D stretch its legs. The 12 cores and 24 threads are likely managing Rust’s server-side calculations, while the RTX 4070 easily keeps up with the pixel workload at this resolution.

At 2560x1440, the balance tips slightly toward the GPU. The FPS on High drops to 88, and on Low it falls to 155. The scaling from Low to High is now a 43% reduction in FPS, compared to a 44% reduction at 1080p. The GPU is becoming more relevant, but the CPU still has headroom. The Medium preset at 1440p produces 104 FPS, which is 17% higher than High, showing that the RTX 4070 is starting to feel the load.

At 3840x2160, the GPU becomes the primary constraint. The FPS on Low is 91, but on High it drops to 52, a 43% reduction. Ultra falls to 39 FPS. The 9900X3D is likely not the issue here; the RTX 4070’s 5 nm Ada Lovelace chip is working hard to fill 8.3 million pixels. The data shows that the CPU’s role shrinks as resolution grows, and the GPU’s role grows. At 4K, the combo is effectively GPU-limited, whereas at 1080p, it is CPU-limited.

The presets also reveal the CPU’s strength. At 1080p Low, the combo hits 225 FPS, which is 77% higher than High. At 1440p Low, it hits 155 FPS, and at 4K Low, 91 FPS. These numbers suggest the CPU can push over 200 FPS in light scenes, but the game’s engine and the GPU’s pixel throughput cap the average.

FAQ

Similar Performance Alternatives

For the CPU, the nearest rivals are all Intel parts. The Intel Core Ultra 5 245KF is the closest, with an average score of 55,093, which is 0.6% higher than the 9900X3D. In Rust, this would translate to nearly identical frame rates, though the 9900X3D’s larger cache may help in specific server-heavy scenarios. The Core Ultra 5 245K scores 54,053, 1.3% lower, and the Intel Xeon 6505P scores 53,701, 2.0% lower. The Core i7-14700F scores 53,620, 2.1% lower. Any of these would pair well with the RTX 4070, but the 9900X3D’s 128 MB L3 cache gives it an edge in Rust’s world simulation.

For the GPU, the RTX 4070 is essentially tied with the NVIDIA Tesla P4, which scores 37,628 (0.1% lower). In practical terms, the Tesla P4 would deliver the same FPS in Rust, but it lacks the 4070’s modern feature set like DirectX 12 Ultimate and Vulkan 1.4 support. The AMD Radeon RX Vega 56 scores 37,507, 0.4% lower, meaning it would be slightly slower in GPU-bound scenes at 4K. The RTX 4080 Mobile scores 38,135, 1.3% higher, but it is a laptop chip, so it may not sustain the same performance in a desktop chassis. The AMD Radeon PRO W6400 scores 37,157, 1.3% lower, which would show a measurable FPS drop at 4K High.

If you were to swap the GPU for a Tesla P4 or RX Vega 56, the combo would still clear 60 FPS at 1440p Ultra, but the 4K Medium preset’s 61 FPS could dip below the threshold. The CPU alternatives would not change the verdict at any resolution, as they are all within 2.1% of each other.

Measured FPS Breakdown

At 3840x2160, the combo delivers 91 FPS on Low, 61 FPS on Medium, 52 FPS on High, and 39 FPS on Ultra. The Medium preset includes a minimum of 52 FPS and a maximum of 71 FPS, showing some variance. The Low and Ultra presets only list average FPS, but the trend is clear: the GPU struggles to maintain 60 FPS above Medium.

At 2560x1440, the performance is far healthier. Low averages 155 FPS, Medium 104 FPS, High 88 FPS, and Ultra 67 FPS. The Medium preset has a minimum of 88 FPS and a maximum of 120 FPS, which is a comfortable range. This resolution is the best balance between visual quality and frame rate, as even Ultra stays above the 60 FPS threshold.

At 1920x1080, the combo excels. Low averages 225 FPS, Medium 151 FPS, High 127 FPS, and Ultra 97 FPS. The Medium preset shows a minimum of 128 FPS and a maximum of 174 FPS. The CPU’s strength is evident here, as the frame rate scales almost linearly with the graphical load. The 9900X3D’s single-thread score of 6,739 in Cinebench R23 and its 24 threads ensure Rust’s main thread and background tasks are both well-served.

The data does not include min/max FPS for most presets, but the Medium presets at each resolution provide insight into variance. At 1080p Medium, the spread is 128 to 174 FPS, a 46 FPS range. At 1440p Medium, the spread is 88 to 120 FPS, a 32 FPS range. At 4K Medium, the spread is 52 to 71 FPS, a 19 FPS range. This suggests that higher resolutions smooth out frame pacing, but the average FPS drops.

The Verdict

This PC can run Rust, and it does so well at 1080p and 1440p. The verdict by resolution is clear. At 1920x1080, all four presets—Low, Medium, High, and Ultra—are playable, with Ultra averaging 97 FPS. At 2560x1440, all presets are also playable, with Ultra averaging 67 FPS. At 3840x2160, only Low and Medium clear the 60 FPS threshold, with Medium averaging 61 FPS. High and Ultra fall short at 52 FPS and 39 FPS respectively.

The data shows that the combo is best suited for 1440p gaming, where it can run the highest preset without compromise. At 1080p, it is overkill, delivering over 200 FPS on Low, which is useful for competitive play but unnecessary for most users. At 4K, the RTX 4070’s 12 GB of GDDR6X memory and 504.2 GB/s bandwidth are not enough to push High and Ultra to playable levels.

The playable threshold is 60 FPS, and the combo exceeds it at 1440p Ultra by 7 FPS. This is a comfortable margin, but not a huge one. If Rust updates add more graphical demands, the 1440p Ultra preset could dip below 60 FPS in busy scenes. The 4K Medium preset, at 61 FPS, is right at the edge and should be considered a borderline case.

Best Settings per Resolution

At 3840x2160, the most demanding preset that stays at or above 60 FPS is Medium, with an average of 61 FPS. The minimum FPS is 52, which means some scenes will drop below the threshold, but the average clears it. Low is also playable at 91 FPS, but Medium offers better visuals for only a 30 FPS cost.

At 2560x1440, the best preset is Ultra, with an average of 67 FPS. This is the highest quality setting available, and it stays above 60 FPS. The next step down, High, averages 88 FPS, but Ultra is the clear choice for visual fidelity.

At 1920x1080, the best preset is also Ultra, with an average of 97 FPS. This leaves significant headroom above the 60 FPS threshold, making it the obvious pick. Low averages 225 FPS, but Ultra’s 97 FPS is still far above playable, and the visual improvement is substantial.

The data suggests that the combo’s optimal configuration is Ultra at 1440p or 1080p. At 4K, Medium is the only preset that balances quality and playability. The 9900X3D and RTX 4070 are a capable pairing, but the GPU’s 4K limitations are the only real constraint.
