Rust

The AMD Ryzen 9 7900X paired with the NVIDIA GeForce RTX 4090 sits at the 85th spot out of 3,723 tested combos for Rust, placing it in the top 2.3% of all configurations evaluated. This is a flagship-tier pairing where the CPU holds the 91st percentile among all processors and the GPU ranks in the 88th percentile among all graphics cards, but the game’s actual frame rates reveal that even this hardware hits a hard ceiling at 4K Ultra.

How This Combo Ranks

The combo’s rank of 85 out of 3,723 tested combinations puts it in the 97.7th percentile of all systems measured for Rust. That ranking is driven by the sheer headroom both components bring: the Ryzen 9 7900X delivers a Cinebench R23 multi-core score of 29,300 and a single-core score of 2,016.5, while the RTX 4090 posts a PassMark G3D score of 38,194 and a Geekbench Vulkan score of 271,631. These are top-shelf numbers individually, and together they place the system well above the vast majority of tested hardware.

However, the data shows that Rust is not purely GPU-bound at the highest settings. At 4K Ultra, the average frame rate drops to 53.6 FPS, which is below the 60 FPS playable threshold. The same system at 4K High runs at 73.3 FPS, meaning the jump from High to Ultra costs roughly 27% performance. This pattern persists at lower resolutions but with more headroom: at 1440p Ultra the combo averages 96 FPS, and at 1080p Ultra it hits 138 FPS. The rank reflects the combo’s ability to crush most settings, but the Ultra preset at 4K exposes a limitation that cheaper combinations might not face as severely due to different scaling characteristics.

The CPU’s 12-core, 24-thread configuration with a 5.60 GHz boost clock ensures that frame pacing remains stable even in Rust’s most entity-dense moments. The GPU’s 24 GB of GDDR6X memory and 1.01 TB/s bandwidth provide ample texture throughput, but the measured data indicates that the Ultra preset’s additional graphical load—likely shadow quality, draw distance, and anti-aliasing—pushes the render pipeline past what the AD102 chip can sustain at 4K. The result is a combo that ranks exceptionally high overall but still requires a settings adjustment for 4K Ultra play.

Best Settings per Resolution

At 3840x2160, the most demanding preset that stays at or above 60 FPS is High, with an average of 73.3 FPS. The Low preset runs at 132.2 FPS and Medium at 87.3 FPS, but Ultra falls to 53.6 FPS, below the playable threshold. For 4K users, High is the sweet spot—it delivers 22% more performance than Medium while still providing the visual fidelity most players expect from a flagship GPU.

At 2560x1440, Ultra is the best playable setting, averaging 96 FPS. This is a comfortable margin above the 60 FPS floor, with High at 124.8 FPS, Medium at 145.9 FPS, and Low at 221.9 FPS. The 1440p Ultra result is particularly notable because it shows the combo has enough headroom to run the game’s maximum settings without dropping below the threshold, unlike at 4K.

At 1920x1080, Ultra again takes the top spot with 138 FPS average. The lower resolution reduces GPU load enough that even the most demanding preset leaves significant performance on the table—Low runs at 246.5 FPS, Medium at 212.8 FPS, and High at 182.8 FPS. For competitive play, the 1080p Low preset offers the highest frame rate, but for visual quality, Ultra remains fully playable with more than double the 60 FPS threshold.

FAQ

Q: Can this PC run Rust at 4K Ultra settings?

A: No. The measured average FPS at 3840x2160 Ultra is 53.6, which is below the 60 FPS playable threshold. The highest playable 4K preset is High at 73.3 FPS.

Q: What is the best 1440p setting for this combo?

A: Ultra is the best playable setting at 2560x1440, with an average of 96 FPS. It clears the 60 FPS threshold by 36 FPS, leaving room for occasional dips without hitting the floor.

Q: How much faster is 1080p Low compared to 1080p Ultra?

A: At 1920x1080, Low averages 246.5 FPS while Ultra averages 138 FPS. Low is approximately 79% faster, but both presets are far above the 60 FPS threshold.

Q: Does the RTX 4090’s 24 GB VRAM help in Rust?

A: The memory capacity is more than sufficient for Rust’s texture loads, but the data shows that the Ultra preset at 4K still drops below 60 FPS. This indicates the bottleneck is compute throughput, not VRAM capacity, since lowering other settings while keeping the same resolution yields much higher frame rates.

Q: What percentile does this combo rank in among all tested systems?

A: It ranks 85th out of 3,723 tested combinations, placing it in the top 2.3% of all systems measured for Rust.

Q: Is the Ryzen 9 7900X or the RTX 4090 the limiting factor at 4K Ultra?

A: The GPU is the limiting factor at 4K Ultra. The CPU’s single-thread score of 2,016.5 in Cinebench R23 and multi-thread score of 29,300 are strong enough to feed the GPU, but the 53.6 FPS result at 4K Ultra—versus 87.3 FPS at Medium—shows the GPU cannot sustain the Ultra preset’s load at that resolution.

Similar Performance Alternatives

The Ryzen 9 7900X’s nearest rivals in benchmark scores include the AMD EPYC 7313P with an average score of 53,206 (0.2% lower), the Intel Xeon Phi 7290 at 53,469 (0.3% higher), the Intel Xeon 634 at 52,974 (0.6% lower), and the Intel Core i7-14700F at 53,620 (0.6% higher). These processors would behave nearly identically in Rust, meaning the same 4K Ultra limitation and similar frame rates at other settings, provided the GPU remains the same.

On the GPU side, the RTX 4090’s nearest rivals are the Intel Arc Pro A60 with an average score of 60,326 (0% difference), the AMD Radeon Pro Vega 48 at 60,140 (0.3% lower), the AMD Radeon Pro W6600M at 61,896 (2.5% higher), and the AMD Radeon PRO V710 at 58,657 (2.9% lower). These GPUs would produce frame rates within a few percentage points of the RTX 4090 in Rust, though none offer the same 24 GB VRAM capacity. For a system with similar overall performance, swapping the RTX 4090 for the Arc Pro A60 would yield nearly identical results, while the Radeon Pro W6600M might push slightly higher averages based on its benchmark score.

The practical takeaway is that the combo’s 4K Ultra limitation is not unique to this exact pairing—any GPU within 3% of the RTX 4090’s average benchmark score would likely show the same sub-60 FPS result at that preset. Conversely, the CPU’s nearest rivals would not change the outcome because Rust’s frame rates at 4K are GPU-bound, as evidenced by the large FPS differences between settings at the same resolution.

Measured FPS Breakdown

At 3840x2160, the average frame rates are: Low at 132.2 FPS, Medium at 87.3 FPS, High at 73.3 FPS, and Ultra at 53.6 FPS. The spread from Low to Ultra is 78.6 FPS, with the largest drop occurring between Medium and High (14 FPS) and between High and Ultra (19.7 FPS). The Ultra preset is the only one that fails to clear the 60 FPS threshold.

At 2560x1440, the results are: Low at 221.9 FPS, Medium at 145.9 FPS, High at 124.8 FPS, and Ultra at 96 FPS. The gap between Low and Medium is 76 FPS, while the gap between High and Ultra is 28.8 FPS. All presets are comfortably playable, with Ultra still 36 FPS above the threshold.

At 1920x1080, the results are: Low at 246.5 FPS, Medium at 212.8 FPS, High at 182.8 FPS, and Ultra at 138 FPS. The difference between Low and Medium is 33.7 FPS, between Medium and High is 30 FPS, and between High and Ultra is 44.8 FPS. Even the lowest preset here exceeds the 4K Low result by 114.3 FPS, showing the strong resolution scaling of the RTX 4090.

The data shows a consistent pattern: as resolution decreases, the relative cost of Ultra settings shrinks. At 4K, Ultra is 60% slower than Low; at 1440p, Ultra is 57% slower than Low; at 1080p, Ultra is 44% slower than Low. This indicates that the GPU’s compute units become the primary constraint at higher resolutions, while at 1080p the CPU’s single-thread performance (2,016.5 in Cinebench R23 single-core) is sufficient to keep the pipeline fed even at Ultra.

The Verdict

Can this PC run Rust? Yes, with one significant caveat. The combo clears the 60 FPS threshold at every resolution tested except 4K Ultra. At 3840x2160, the playable settings are High (73.3 FPS), Medium (87.3 FPS), and Low (132.2 FPS), with Ultra falling to 53.6 FPS. At 2560x1440, all four presets are playable, with Ultra at 96 FPS as the best visual option. At 1920x1080, all four presets are playable, with Ultra at 138 FPS.

The practical verdict is that this system is an exceptional Rust machine for 1080p and 1440p gaming, capable of running the game at maximum settings with frame rates well above the playable threshold. For 4K users, the recommendation is to use the High preset, which delivers 73.3 FPS average—a solid experience that sacrifices some visual fidelity but maintains smooth gameplay. The Ultra preset at 4K is the only configuration that fails the 60 FPS test, but the margin is narrow (6.4 FPS below threshold), suggesting that minor tweaks to specific in-game settings—such as reducing shadow quality or draw distance—could push it back above 60 FPS without dropping to Medium. Overall, this combo ranks 85th out of 3,723 because it handles the vast majority of Rust’s settings and resolutions with authority, but it is not a universal 4K max-settings machine.
