Rust

The AMD Ryzen 5 5600X paired with the NVIDIA GeForce RTX 4080 delivers a broad performance envelope in Rust, with frame rates that scale predictably with resolution and settings. The data shows a system capable of high refresh rates at 1080p, but one that is increasingly constrained by graphical load as resolution climbs to 4K.

Resolution Scaling

The measured FPS data reveals a clear pattern of diminishing returns as resolution increases. At 1080p with Low settings, the combo achieves an average of 197 FPS. Moving to 1440p Low drops this to 174 FPS, a 11.7% reduction, while 4K Low yields 117 FPS, a 40.6% decline from the 1080p baseline. This scaling indicates that even at Low settings, the GPU is beginning to feel the pressure of additional pixels, though the frame rates remain highly playable.

The gap widens dramatically at higher settings. With High settings, the system produces 160 FPS at 1080p, 112 FPS at 1440p (a 30% drop), and 66 FPS at 4K (a 58.8% drop from 1080p). This steeper curve at High settings compared to Low suggests that the game's higher visual fidelity options amplify the workload per pixel, making resolution a more significant factor.

Ultra settings show the most severe scaling. The average frame rate falls from 124 FPS at 1080p to 85 FPS at 1440p, and finally to 50 FPS at 4K. The 4K Ultra result is less than half the 1080p Ultra figure, demonstrating that this configuration is heavily taxed by the combination of maximum graphical details and high pixel counts. The scaling from 1440p to 4K at Ultra represents a 41.2% performance loss, which is the largest single-step decline in the entire dataset.

The Medium preset offers a middle ground, with 170 FPS at 1080p, 133 FPS at 1440p, and 79 FPS at 4K. The 4K Medium result, with a minimum of 67 FPS, shows that the system can maintain a playable experience at 4K if settings are moderated. The overall trend suggests that the RTX 4080 is the primary limiting factor at 4K, particularly with higher presets, while the Ryzen 5 5600X appears sufficient to feed the GPU at lower resolutions where frame rates are exceptionally high.

GPU Role

The NVIDIA GeForce RTX 4080 is the dominant component in this pairing, and its specifications directly correlate with the observed performance. The GPU features 16 GB of GDDR6X memory on a 256-bit bus, providing a bandwidth of 716.8 GB/s. This memory configuration is substantial for Rust, which is known for its large maps and frequent asset streaming. The ample 16 GB capacity ensures that texture data and world geometry are unlikely to spill into slower system memory, a critical factor at 4K resolution where memory pressure is highest.

The GPU's clock speeds are also relevant. With a base clock of 2205 MHz and a boost clock of 2505 MHz, the RTX 4080 maintains high operating frequencies under load. The memory operates at 1400 MHz, with 22.4 Gbps effective speed. These clocks, combined with the 9728 shading units and 304 TMUs, allow the card to process the complex lighting and shadow calculations that Rust's survival environments require.

The benchmark results for the RTX 4080 show it performing at the 86th percentile among all GPUs, with an average benchmark score of 54247. Its nearest rival is the NVIDIA GeForce RTX 4080 SUPER, which scores 54209, a negligible 0.1% difference. This places the 4080 in a position where it is statistically tied with its immediate successor in synthetic tests. The data shows the 4080 outperforming the AMD Radeon Pro W5700X by 1.1% and the AMD Radeon RX 6750 GRE 12 GB by 2.6%.

The GPU's FP32 performance of 48.74 TFLOPS and texture rate of 761.5 GTexel/s provide the raw compute necessary for high-resolution rendering. However, the measured FPS at 4K Ultra (50 FPS) indicates that even this powerful GPU is fully saturated by Rust's maximum settings. The pixel rate of 280.6 GPixel/s is a limiting factor at 4K, as the GPU must fill over 8 million pixels per frame.

CPU Role

The AMD Ryzen 5 5600X is a 6-core, 12-thread processor based on the Zen 3 architecture, manufactured on a 7 nm process. It has a base clock of 3.70 GHz and a boost clock of 4.60 GHz. The CPU's 32 MB of L3 cache is a significant asset for Rust, as the game's open-world environment requires frequent data access. The 51.2 GB/s memory bandwidth, while not exceptional, is sufficient for the game's needs.

The CPU's benchmark results show a balanced profile. Its single-thread score in Cinebench R23 is 1541, while its multi-core score is 11838. The 3DMark tests reveal scaling from 1793 with 2 threads to 5588 with max threads, indicating good thread utilization. The PassMark single-thread score of 3364 is strong, which is crucial for Rust's physics and logic calculations that are often single-threaded.

The CPU's role in this game is evident from the FPS data. At 1080p Low, the system produces 197 FPS, which is a frame rate where the CPU's single-thread performance becomes the primary driver. The fact that the CPU can sustain this level of performance indicates that its 4.60 GHz boost clock is being effectively utilized. The 75th percentile ranking among all CPUs confirms that the 5600X is a solid performer, though not at the very top of the hierarchy.

The CPU's nearest rivals in synthetic benchmarks include the AMD Ryzen 7 4800H (0.1% faster), the AMD Ryzen 5 PRO 6650U (0.5% slower), and the Intel Core i7-11700 (0.5% slower). This tight grouping shows that the 5600X is competitive with a range of processors, but its 6-core/12-thread configuration may limit performance in scenarios that heavily utilize multiple cores. In Rust, however, the data shows that the CPU does not become a significant bottleneck until very high frame rates, as evidenced by the 197 FPS result at 1080p Low.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across three resolutions and four settings levels.

At 1920x1080, the system achieves its highest frame rates. With Low settings, the average FPS is 197. Moving to Medium, the average is 170 FPS, with a minimum of 144 FPS and a maximum of 195 FPS. The High preset yields 160 FPS, while Ultra drops to 124 FPS.
