Rust

The AMD Ryzen 9 9900X paired with the NVIDIA GeForce RTX 4080 delivers measured frame rates in Rust across three resolutions and four quality presets. The CPU, a 12-core Zen 5 part with a 4.40 GHz base and 5.60 GHz boost, and the GPU, an Ada Lovelace card with 16 GB GDDR6X, together place this combination at rank 177 out of 3,723 tested combos. The CPU's launch MSRP is $499, and the GPU's launch MSRP is 1,199 USD. Benchmark data is measured, not estimated, and the playable threshold is set at 60 FPS.

Measured FPS Breakdown

At 3840x2160, the average frame rates are 117 FPS on Low, 79 FPS on Medium, 66 FPS on High, and 50 FPS on Ultra. Only Medium provides min/max figures: 67 FPS minimum and 90 FPS maximum. The drop from Low to Ultra is 67 FPS, a 57% reduction. High remains above the 60 FPS threshold, but Ultra falls below it, making High the highest preset that stays playable at 4K.

At 2560x1440, all presets clear 60 FPS. Low averages 198 FPS, Medium 133 FPS (min 113, max 153), High 112 FPS, and Ultra 85 FPS. The gap between Low and Ultra is 113 FPS. Even the most demanding setting, Ultra, maintains a comfortable margin above the playable threshold.

At 1920x1080, the CPU and GPU combination produces very high frame rates. Low averages 274 FPS, Medium 193 FPS (min 164, max 222), High 163 FPS, and Ultra 124 FPS. The difference from Low to Ultra is 150 FPS, the largest absolute drop across all resolutions. No preset at 1080p comes close to the 60 FPS floor.

The scaling pattern shows that as resolution increases, the absolute FPS loss from Low to Ultra narrows. At 1080p the drop is 150 FPS, at 1440p it is 113 FPS, and at 4K it is 67 FPS. This suggests the GPU becomes the primary bottleneck at higher resolutions, while at 1080p the CPU’s headroom is more visible, particularly on Low settings where the frame rate reaches 274 FPS.

Similar Performance Alternatives

The nearest rivals for the Ryzen 9 9900X, based on average benchmark scores, are the AMD EPYC 9015 (score 57,555, delta −0.1%), the AMD EPYC 7313 (57,399, +0.2%), the Intel Core i9-14900 (58,115, −1.1%), and the Intel Xeon Platinum 8260M (58,323, −1.4%). These deltas are all within 1.5% of the 9900X’s average score of 57,498, meaning they occupy the same performance tier in synthetic multi-threaded tests. In Rust, where frame rates at lower resolutions are often limited by CPU throughput, these alternatives would likely produce similar average FPS figures, though direct game measurements are not provided.

For the RTX 4080, the closest rivals are the RTX 4080 SUPER (54,209, +0.1%), the AMD Radeon Pro W5700X (54,828, −1.1%), the AMD Radeon RX 6750 GRE 12 GB (55,698, −2.6%), and the AMD Radeon 8060S (55,757, −2.7%). The GPU’s average benchmark score is 54,247. The tiny delta percentages indicate that these cards deliver nearly identical raw compute performance. At 4K Ultra, where the RTX 4080 manages 50 FPS, a similarly-scoring card would be expected to land within a few frames of that mark, though again no per-game data exists for those alternatives.

How This Combo Ranks

The combination of Ryzen 9 9900X and RTX 4080 holds rank 177 out of 3,723 tested configurations in Rust. That places it in the top 4.8% of all combos. The rank reflects the aggregate of measured FPS across all resolutions and presets. Given that the combo exceeds 60 FPS at every resolution except 4K Ultra, and maintains high average frame rates even at 4K High, the ranking is consistent with a high-end pairing. The CPU’s percentile versus all CPUs is 92, and the GPU’s percentile versus all GPUs is 86, both indicating strong relative standing.

CPU and GPU Roles

The measured FPS data reveals how the balance between CPU and GPU shifts across resolutions and presets. At 1920x1080, the Low preset reaches 274 FPS, a value that far exceeds what the GPU alone would typically deliver; this indicates that the CPU is capable of feeding the GPU with more than enough draw calls and game logic. The gap between Low and Ultra at 1080p is 150 FPS, the largest of any resolution, suggesting that the GPU becomes the limiting factor as graphical load increases, but the CPU still has headroom to spare.

Moving to 2560x1440, the Low preset drops to 198 FPS and Ultra to 85 FPS. The absolute difference between Low and Ultra shrinks to 113 FPS. This narrowing implies that the GPU is now doing more of the work, and the CPU’s contribution is relatively less prominent. At 3840x2160, the Low preset yields 117 FPS and Ultra only 50 FPS. The difference is just 67 FPS, the smallest of the three resolutions. Here the GPU is clearly the dominant bottleneck; even on Low settings, the frame rate is constrained by pixel throughput and memory bandwidth, not by CPU processing.

The data also shows that the CPU’s single-thread performance is strong enough to avoid holding back the GPU at lower resolutions. The Ryzen 9 9900X’s single-thread benchmark scores (3dmark single-thread 1,286, Cinebench R23 single-core 2,253, Geekbench single-core 3,010) are high, and the passmark single-thread score of 4,672 places it in the 92nd percentile overall. In Rust, which is known to be sensitive to single-core performance, this CPU’s headroom is evident from the 274 FPS at 1080p Low. Conversely, at 4K Ultra, the RTX 4080’s raw compute and memory bandwidth (716.8 GB/s) are insufficient to maintain 60 FPS, indicating a GPU-bound scenario.

Best Settings per Resolution

At 3840x2160, the most demanding preset that stays at or above 60 FPS is High, with an average of 66 FPS. Medium and Low also remain playable, but High offers the highest visual quality while still meeting the threshold.

At 2560x1440, Ultra is the best playable setting, averaging 85 FPS. All lower presets also exceed 60 FPS, but Ultra provides the maximum visual fidelity.

At 1920x1080, Ultra is again the best playable setting, with an average of 124 FPS. Even at the highest preset, the frame rate is more than double the 60 FPS floor.

The Verdict

This PC can run Rust comfortably. The verdict by resolution is clear: at 3840x2160, High, Medium, and Low are playable, with High being the best at 66 FPS; Ultra is not playable at 50 FPS. At 2560x1440, all presets including Ultra are playable, with Ultra averaging 85 FPS. At 1920x1080, all presets are playable, with Ultra averaging 124 FPS. The combination of the Ryzen 9 9900X and RTX 4080 delivers a smooth experience at 1080p and 1440p across all settings, and at 4K it handles High settings without dropping below 60 FPS. For players who prioritize frame rate over visual fidelity, even 4K Low at 117 FPS is available. The data indicates a well-balanced pairing that is CPU-limited only at low resolutions and high settings, and GPU-limited at 4K Ultra.
