Rust

The AMD Ryzen 9 5950X and NVIDIA GeForce RTX 4080 SUPER combination delivers a robust Rust experience, but the data reveals a system where the GPU becomes the primary bottleneck at higher resolutions. At 1080p, the CPU demonstrates its strength, while at 4K, the graphics card’s workload dominates the frame rate. The measured results show a clear scaling pattern across the four settings presets, with the performance gap between Low and Ultra widening as resolution increases.

Resolution Scaling

The frame rate drop from 1080p to 4K is substantial and consistent with a GPU-limited scenario at higher pixel counts. At Low settings, the average FPS falls from 203.2 at 1920x1080 to 178.0 at 2560x1440, then to 114.3 at 3840x2160. This represents a 43.7% reduction from 1080p to 4K, indicating that the RTX 4080 SUPER’s rendering workload scales heavily with resolution. The pattern is similar at High settings, where 164.2 FPS at 1080p drops to 109.9 FPS at 1440p and 67.4 FPS at 4K, a 59% decrease from the lowest to highest resolution.

The scaling behavior suggests that at 1080p, the CPU is more involved, limiting the maximum frame rate. The difference between Low and High at 1080p is only 39 FPS (203.2 vs 164.2), whereas at 4K, the same settings gap is 46.9 FPS (114.3 vs 67.4). This widening gap indicates that as resolution increases, the GPU becomes the limiting component, making the graphics card’s performance the deciding factor. The Ultra preset at 4K yields 52 FPS, which is barely playable for a survival game, while 1440p Ultra delivers 87.3 FPS, a comfortable margin above 60 FPS. The data clearly shows that for smooth 4K gameplay, players must reduce settings to Medium (79.5 FPS) or Low (114.3 FPS).

CPU Role

The Ryzen 9 5950X is a 16-core, 32-thread processor based on the Zen 3 architecture, with a base clock of 3.40 GHz and a boost clock of 4.90 GHz. Its benchmark scores position it in the 93rd percentile of all CPUs, with an average benchmark score of 49062. The multi-threaded performance is strong, as shown by a Cinebench R23 multi-core score of 38607, but Rust’s engine does not appear to scale perfectly with this many cores. The single-thread score of 5450 in Cinebench R23 is more relevant for gaming, and the 3DMark single-thread score of 944 reflects this.

The CPU’s nearest rivals include the Intel Core i5-14600K, which has an average score of 49166, just 0.2% higher than the 5950X. This close margin indicates that for gaming workloads like Rust, the 5950X’s high core count does not provide a significant advantage over a newer, higher-clocked competitor. The 3DMark 16-thread score of 10810 and max-thread score of 11597 show that the CPU can handle heavy multi-threaded tasks, but Rust’s performance at 1080p Low (203.2 FPS) suggests that the processor is not the primary limiter at lower resolutions. At 1080p Ultra, the frame rate drops to 120.9 FPS, which is still high, but the CPU’s single-thread performance becomes more critical as settings increase and draw calls multiply.

FAQ

Q: What is the average FPS at 1440p with High settings?

A: The measured average FPS at 2560x1440 with High settings is 109.9 FPS.

Q: How does the RTX 4080 SUPER compare to its nearest rival in benchmark scores?

A: The GPU’s average benchmark score is 53610, which is 0.2% higher than the AMD Radeon RX 6900 XT (53489) and 2.1% higher than the AMD Radeon RX 7700S (52505).

Q: Does the CPU bottleneck at 1080p Low settings?

A: The 1080p Low result of 203.2 FPS is the highest recorded, but the 5950X’s single-thread score of 944 in 3DMark suggests it can drive high frame rates; however, the GPU still renders the scene, and the data shows a 39 FPS difference between Low and High at this resolution, indicating some CPU involvement.

Q: What is the best settings preset for 4K gaming?

A: At 3840x2160, only Low (114.3 FPS) and Medium (79.5 FPS) exceed 60 FPS. High (67.4 FPS) is playable but close to the threshold, while Ultra (52 FPS) falls below it.

Q: How does the CPU’s multi-threaded performance affect Rust?

A: The Cinebench R23 multi-core score of 38607 and PassMark multi-thread score of 45424 show strong parallel performance, but the 3DMark 2-thread score of 1856 indicates that Rust benefits more from single-thread speed, as evidenced by the 1080p results.

Q: What is the frame rate difference between Low and Ultra at 1440p?

A: The average FPS drops from 178.0 on Low to 87.3 on Ultra at 2560x1440, a difference of 90.7 FPS.

Measured FPS Breakdown

At 1920x1080, the RTX 4080 SUPER and Ryzen 9 5950X produce high frame rates across all settings. Low settings average 203.2 FPS, Medium 173.2 FPS, High 164.2 FPS, and Ultra 120.9 FPS. The scaling from Low to Ultra is a 40.5% reduction, with the largest single drop occurring between High and Ultra (43.3 FPS). This suggests that Ultra settings introduce significant rendering costs, likely from shadows and post-processing effects.

Moving to 2560x1440, the average FPS at Low is 178.0, Medium 130.3, High 109.9, and Ultra 87.3. The gap between Low and Ultra widens to 90.7 FPS, but the relative drop is similar to 1080p. The 1440p results remain playable at all settings, with Ultra still above 60 FPS. The data shows a 26.8% reduction from 1080p to 1440p at Low settings, indicating that the GPU’s pixel throughput is becoming more influential.

At 3840x2160, the frame rates drop significantly. Low settings average 114.3 FPS, Medium 79.5 FPS, High 67.4 FPS, and Ultra 52 FPS. The difference between Low and Ultra is 62.3 FPS, and the reduction from 1080p to 4K at Low settings is 43.7%. The Ultra preset at 4K is the only configuration that falls below 60 FPS, making it unsuitable for competitive play. The data indicates that the GPU’s memory bandwidth of 736.3 GB/s and 16 GB of VRAM are sufficient for 4K, but the rendering load on the AD103 chip limits performance at the highest quality settings.

GPU Role

The NVIDIA GeForce RTX 4080 SUPER is built on the Ada Lovelace architecture with a 5 nm process and features 10240 shading units, 80 RT cores, and 320 tensor cores. Its boost clock of 2550 MHz and 16 GB of GDDR6X memory on a 256-bit bus provide a bandwidth of 736.3 GB/s. The GPU’s average benchmark score is 53610, placing it in the 88th percentile of all GPUs. Its nearest rival, the AMD Radeon RX 6900 XT, scores 53489, a 0.2% difference, while the RTX 5070 Ti is 2.9% lower with a score of 52086.

The GPU’s role in Rust is clear from the resolution scaling data. At 1080p, the CPU can feed frames fast enough, but the GPU still renders the scene, resulting in 203.2 FPS on Low. At 4K, the GPU becomes the sole bottleneck, as evidenced by the 114.3 FPS on Low versus 67.4 FPS on High. The 52 FPS at 4K Ultra shows that the RTX 4080 SUPER is not overkill for this game at maximum settings; it is just sufficient for playable frame rates. The PassMark G3D score of 34245 and 3DMark Steel Nomad score of 6600 reflect the GPU’s strong compute capabilities, but Rust’s draw calls and shader complexity at Ultra settings push the card to its limits. The GPU’s FP32 performance of 52.22 TFLOPS and texture rate of 816.0 GTexel/s are high, yet the 4K Ultra result of 52 FPS indicates that the game’s engine is demanding on both pixel fill rate and memory bandwidth. The 16 GB VRAM is not a limiting factor, as the game likely fits within this capacity, but the rendering load is the primary constraint.
