# Rust Performance Analysis: AMD Ryzen 7 5700X + NVIDIA GeForce RTX 4080

The AMD Ryzen 7 5700X paired with the NVIDIA GeForce RTX 4080 delivers a broad performance envelope in Rust, ranging from 50 FPS at 4K Ultra to 199 FPS at 1080p Low. This combination ranks 373rd out of 3,723 tested combos in the database, placing it in the top 10% of all configurations. The data shows a system that is consistently playable across all tested settings, though the gap between Low and Ultra presets widens significantly as resolution increases, revealing where each component takes the lead.

Resolution Scaling

The measured FPS data shows a predictable decline as resolution climbs from 1920x1080 to 3840x2160, but the magnitude of that drop varies considerably by settings preset. At Low settings, the average frame rate falls from 199 FPS at 1080p to 175 FPS at 1440p, then to 117 FPS at 4K — a cumulative reduction of roughly 41% from the 1080p baseline. This relatively shallow curve at Low settings suggests the GPU has ample headroom at lower resolutions, with the CPU likely becoming more influential as pixel count decreases.

At Ultra settings, the scaling story is different. The average FPS drops from 124 at 1080p to 85 at 1440p, then to 50 at 4K — a total loss of approximately 60% from the 1080p figure. The steeper decline at Ultra indicates that the higher preset's additional rendering load, likely including more detailed shadows, textures, and post-processing effects, places substantially more pressure on the GPU as resolution increases. The 4K Ultra result of 50 FPS is the lowest measured value in the entire dataset, showing that this combination reaches its practical limit at that configuration.

The Medium preset offers the most complete data, with min and max FPS recorded at all three resolutions. At 1080p Medium, the average is 171 FPS with a range of 145 to 196 FPS. Moving to 1440p Medium drops the average to 133 FPS, with a range of 113 to 153 FPS. At 4K Medium, the average falls to 79 FPS, ranging from 67 to 90 FPS. The frame-time consistency, as indicated by the min-to-max spread, remains relatively tight across resolutions — roughly 51 FPS of spread at 1080p, 40 FPS at 1440p, and 23 FPS at 4K. This narrowing spread at higher resolutions suggests that the GPU becomes more consistently saturated, reducing the variability caused by CPU-driven frame spikes.

The High preset sits between Medium and Ultra in absolute terms: 161 FPS at 1080p, 112 FPS at 1440p, and 66 FPS at 4K. The percentage drop from 1080p to 4K at High is about 59%, nearly identical to the Ultra preset's decline. This similarity implies that High and Ultra place comparable relative loads on the GPU, while Low and Medium scale more gently. The data indicates that at 1080p and 1440p, the RTX 4080 is not the primary limiting factor at lower presets — the Ryzen 7 5700X's 8 cores and 16 threads become more relevant as the GPU waits for CPU-drawn frames.

GPU Role

The NVIDIA GeForce RTX 4080 is the dominant component in this pairing, and its 16 GB of GDDR6X memory on a 256-bit bus provides 716.8 GB/s of bandwidth. In Rust, which is known for large, persistent world data and frequent texture streaming, this memory capacity and bandwidth are critical for maintaining consistent frame rates at higher resolutions. The 4K High result of 66 FPS and 4K Medium of 79 FPS demonstrate that the GPU's memory subsystem is sufficient for the game's demands at these settings, as neither drops to unplayable levels.

The GPU's clock behavior — a base of 2205 MHz and a boost of 2505 MHz — combined with its 9728 shading units and 304 texture mapping units, explains why the card scales well between 1080p and 1440p. At 1080p Low, the 4080 produces 199 FPS, and at 1440p Low it still delivers 175 FPS. The relatively small performance penalty of about 12% from 1080p to 1440p at Low indicates that the GPU is not fully utilized at the lower resolution and lower preset. The Ada Lovelace architecture, built on a 5 nm process at TSMC with 45,900 million transistors, gives the card substantial raw compute headroom — 48.74 TFLOPS of FP32 performance — that Rust's moderate graphical demands do not fully tax at these settings.

However, at 4K Ultra, the RTX 4080's limits become evident. The 50 FPS average is the lowest in the dataset, and the 76 RT cores and 112 ROPs are likely contributing to the rendering pipeline at a level that saturates the GPU. The pixel rate of 280.6 GPixel/s and texture rate of 761.5 GTexel/s are high, but Rust's Ultra preset includes effects that stress these units simultaneously. The GPU's 86th percentile ranking among all GPUs, with an average benchmark score of 54,247, places it near the top of the performance hierarchy, yet the 4K Ultra result shows that even top-tier hardware faces challenges at maximum settings in this game.

The GPU's nearest rivals in benchmark scores — the RTX 4080 SUPER at 54,209 (0.1% delta), the AMD Radeon Pro W5700X at 54,828 (-1.1%), and the AMD Radeon RX 6750 GRE 12 GB at 55,698 (-2.6%) — are all within a narrow margin of the 4080. This suggests that in Rust, the measured FPS differences between these cards would be small at most settings, reinforcing that the 4080's 16 GB VRAM and high bandwidth are competitive but not uniquely superior for this title.

CPU Role

The AMD Ryzen 7 5700X contributes 8 cores and 16 threads based on the Zen 3 architecture, with a base clock of 3.40 GHz and a boost clock of 4.60 GHz. Its 32 MB of shared L3 cache is particularly relevant for Rust, a game that frequently loads and reloads world assets as players move across the map. The CPU's 3DMark 16-thread score of 6,858 and max-thread score of 6,850 indicate strong multi-threaded performance, while the single-thread score of 921 is moderate. Rust's game logic, including entity updates, physics calculations, and network synchronization, benefits from both high single-thread throughput and the ability to distribute work across multiple cores.

At 1080p Low, the system hits 199 FPS, which is close to the practical ceiling for many displays and suggests the CPU is keeping pace with the GPU's output. The fact that 1080p Low (199 FPS) is only slightly higher than 1080p Medium (171 FPS) — a 16% gap — indicates that the CPU is not the primary bottleneck at these settings; the GPU is still doing meaningful work even at Low. However, the 1080p Ultra result of 124 FPS versus 1080p High at 161 FPS shows a 23% drop, which is larger than the GPU-only scaling would predict, hinting that the CPU's per-core performance — a Cinebench R23 single-core score of 1,499 — becomes more critical as the preset adds CPU-intensive simulation elements.

The 5700X's 65 W TDP and 7 nm process node, with a die size of 74 mm² and 4,150 million transistors, provide an efficient platform that does not thermally throttle in typical desktop configurations. The CPU's passmark multithread score of 26,612 and floating-point math score of 51,842 demonstrate robust compute capabilities for Rust's background simulation. The 3DMark 2-thread score of 1,821 and 4-thread score of 3,512 show that scaling from 2 to 4 threads is nearly linear, which is beneficial for Rust's multi-threaded render and update loops.

The CPU's nearest rivals, including the Intel Core i5-12600K at 27,578 (0% delta), the AMD Ryzen 7 5800 at 27,535 (0.2%), and the AMD Ryzen 5 7600X at 27,636 (-0.2%), all sit within a fraction of a percent in average benchmark scores. This tight grouping means that in Rust, the 5700X's performance is essentially interchangeable with these alternatives at the same GPU. The CPU's 79th percentile ranking among all CPUs, with an average benchmark score of 27,578, places it comfortably in the upper tier, and the measured FPS data confirms that it does not hold back the RTX 4080 in most scenarios — the exception being the 4K Ultra result, where the GPU is clearly the limiting factor.

FAQ

Q: What is the best resolution to play Rust with this CPU and GPU combination?

A: The data shows that 1440p provides the best balance of performance and visual quality. At 1440p High, the average FPS is 112, which is smooth for most players, while 4K High drops to 66 FPS and 4K Ultra falls to 50 FPS. The 1080p results are higher but do not offer a meaningful visual upgrade for the additional pixel density loss.

Q: How much FPS do I lose going from 1080p to 4K at the same settings?

A: At Low settings, the average FPS drops from 199 at 1080p to 117 at 4K, a decline of 82 FPS. At Medium, the drop is from 171 to 79, a loss of 92 FPS. At High, the drop is from 161 to 66, a loss of 95 FPS. At Ultra, the drop is from 124 to 50, a loss of 74 FPS. The percentage loss is steepest at High and Ultra, around 59-60%.

Q: Is 4K Ultra playable with this hardware?

A: The measured 4K Ultra average is 50 FPS, which is technically playable but below the 60 FPS threshold many players prefer. The 4K Medium preset at 79 FPS offers a much smoother experience with only a modest visual downgrade. If 4K is the target, Medium or High settings are the recommended choices.

Q: How does the RTX 4080 compare to its closest rivals in this game?

A: The RTX 4080's average benchmark score is 54,247, with the RTX 4080 SUPER at 54,209 (0.1% delta) and the AMD Radeon Pro W5700X at 54,828 (-1.1%). These differences are negligible in real-world Rust performance, so the measured FPS would be nearly identical across these cards at the same settings.

Q: Does the Ryzen 7 5700X bottleneck the RTX 4080 in Rust?

A: The data suggests minimal bottlenecking at most settings. At 1080p Low, the system achieves 199 FPS, and at 1080p Medium it reaches 171 FPS, indicating the CPU can feed the GPU efficiently. The only scenario where the CPU might become more relevant is at 1080p Low, where the GPU has excess capacity but the CPU's single-thread performance (Cinebench R23 single-core score of 1,499) could limit frame rates above 200 FPS.

Q: What is the frame-time consistency like at Medium settings?

A: At 1080p Medium, the FPS ranges from 145 to 196, a spread of 51 FPS. At 1440p Medium, the range is 113 to 153, a spread of 40 FPS. At 4K Medium, the range is 67 to 90, a spread of 23 FPS. The shrinking spread at higher resolutions indicates more consistent frame pacing, as the GPU becomes the steady limiting factor.

Settings Recommendations

The measured data points to the Medium preset as the optimal choice for most players, regardless of resolution. At 1080p Medium, the system delivers 171 FPS average with a min of 145 FPS, which is well above the 144 Hz refresh rate common on gaming monitors. At 1440p Medium, the 133 FPS average with a min of 113 FPS still exceeds 100 FPS, providing a smooth experience on high-refresh displays. Even at 4K Medium, the 79 FPS average with a min of 67 FPS stays above the 60 FPS threshold for standard displays, making it viable for 4K gaming without sacrificing too much visual fidelity.

The High preset is a reasonable alternative for players who prioritize visual quality over raw frame rate. At 1440p High, the 112 FPS average is still playable on most monitors, and at 1080p High, the 161 FPS average is excellent. However, at 4K High, the 66 FPS average drops below what many competitive players consider acceptable, and the lack of min FPS data makes it harder to assess worst-case performance. The Ultra preset is not recommended for any resolution in this dataset — even at 1080p, the 124 FPS average is lower than the Medium preset's 171 FPS, and the visual improvement from High to Ultra is generally marginal in Rust. The 4K Ultra result of 50 FPS is the only configuration that falls below 60 FPS, reinforcing that this preset is best avoided unless a player prioritizes maximum fidelity over smoothness.

For players with 144 Hz or 165 Hz monitors, the Low preset at 1080p (199 FPS) or 1440p (175 FPS) offers the highest possible frame rates, though the visual compromise may be significant for a game with large open environments. The Medium preset at 1440p, with its 133 FPS average and 113 FPS minimum, provides a strong combination of visual quality and performance that is difficult to beat based on the measured data.

Measured FPS Breakdown

At 1920x1080, the system produces its highest frame rates across all presets. Low settings yield an average of 199 FPS, Medium delivers 171 FPS with a range of 145 to 196, High reaches 161 FPS, and Ultra drops to 124 FPS. The gap between Low and Ultra is 75 FPS, representing a 38% reduction from the Low baseline. The Medium preset's min FPS of 145 is higher than the Ultra average of 124, showing that the step from Medium to Ultra carries a substantial performance penalty.

At 2560x1440, the frame rates remain strong but show the expected decline. Low averages 175 FPS, Medium averages 133 FPS with a range of 113 to 153, High averages 112 FPS, and Ultra averages 85 FPS. The drop from 1080p to 1440p is 12% at Low, 22% at Medium, 30% at High, and 31% at Ultra. The Medium preset's min FPS of 113 is notable, as it stays above 100 FPS even in the worst-case measured frame. This makes 1440p Medium the most consistent high-performance configuration in the dataset.

At 3840x2160, the system approaches its limits. Low averages 117 FPS, Medium averages 79 FPS with a range of 67 to 90, High averages 66 FPS, and Ultra averages 50 FPS. The 4K Medium min FPS of 67 is the lowest minimum recorded for any Medium preset, but it still exceeds the 60 FPS threshold for standard 60 Hz displays. The 4K High and Ultra results fall below 70 FPS, and the Ultra preset's 50 FPS average is the only measured configuration that drops below 60 FPS at any point. The scaling from 1440p to 4K is steepest at High (41% reduction) and Ultra (41% reduction), while Low (33%) and Medium (41%) show similar patterns.

How This Combo Ranks

This particular combination of the AMD Ryzen 7 5700X and NVIDIA GeForce RTX 4080 ranks 373rd out of 3,723 tested combos in Rust, placing it in the top 10% of all configurations. The rank reflects the system's ability to maintain high frame rates across most settings, with only the 4K Ultra configuration falling below 60 FPS. The 5700X's 79th percentile CPU ranking and the RTX 4080's 86th percentile GPU ranking combine to produce a system that is well-balanced for Rust's demands, where both CPU-bound simulation and GPU-bound rendering play significant roles.

The rank of 373 out of 3,723 means that 3,350 other combos perform worse in Rust, while 372 perform better. The combos that outperform this one likely include higher-tier CPUs such as the Ryzen 7 5800X3D or Ryzen 9 series, as well as more powerful GPUs like the RTX 4090. However, the data shows that the 5700X and 4080 pairing delivers frame rates that are competitive with much more expensive setups at 1080p and 1440p, where the CPU's 8 cores and 16 threads are sufficient to feed the GPU's output. At 4K, the GPU becomes the limiting factor, and the 4080's 50 FPS at Ultra places it below the 60 FPS target that many higher-ranked combos likely achieve.

The rank also reflects the balance between the two components. The 5700X's average benchmark score of 27,578 is essentially identical to its nearest rivals, meaning that swapping in an Intel Core i5-12600K or AMD Ryzen 5 7600X would produce nearly identical Rust performance. Similarly, the RTX 4080's score of 54,247 is within 0.1% of the RTX 4080 SUPER, so the measured FPS would not change meaningfully with that upgrade. This suggests that the 373rd rank is not a reflection of any single weak component, but rather the natural performance ceiling of this mid-to-high-tier pairing in a game that scales well with both CPU and GPU resources. The data confirms that this combo is a solid choice for Rust players targeting 1080p or 1440p at high refresh rates, with the understanding that 4K Ultra demands more than this hardware can deliver.
