Rust

The AMD Ryzen 5 7500F paired with the AMD Radeon RX 6800 XT delivers a robust Rust experience, with performance scaling predictably from high refresh rate 1080p play to more demanding 4K resolutions. The data shows a system that is well-balanced for this survival title, though the specific workload characteristics of Rust create distinct bottlenecks at different settings.

Resolution Scaling

The measured FPS data reveals a clear and expected trend as resolution increases, but the rate of decline offers critical insight into where the system's limits lie. At 1080p with Low settings, the combo achieves a commanding 209 FPS average. This figure represents the upper echelon of what the hardware can produce, suggesting that the CPU is doing the heavy lifting at this lower resolution. The performance drop from 1080p to 1440p is steep but not catastrophic. At Low settings, the average FPS falls from 209 to 144, a reduction of 65 FPS. This indicates a significant shift, but the system retains a very high frame rate.

The transition to 4K reveals the most dramatic shift in performance. At 2160p, the average FPS at Low settings drops to 85, a substantial 59 FPS decline from the 1440p result. This pattern strongly suggests that as resolution increases, the workload transitions from the CPU to the GPU. The 1080p to 1440p jump shows a 31% performance reduction, while the 1440p to 4K jump at Low settings shows a 41% reduction. This increasing percentage of FPS loss with each resolution step indicates that the GPU is becoming the primary limiting component at higher resolutions.

The scaling across all settings follows a consistent pattern. At High settings, the average FPS goes from 119 at 1080p to 82 at 1440p and finally to 48 at 4K. The performance drops are 31% and 41% respectively, mirroring the Low settings. This consistent scaling suggests that the game's engine has a largely linear relationship with resolution, but the system is increasingly constrained by the GPU's ability to fill pixels. The data implies that at 1080p, the Ryzen 5 7500F's single-thread performance is likely the limiting factor, while at 4K, the RX 6800 XT's raw throughput determines the final frame rate.

The Ultra settings tell a similar story, starting at 90 FPS at 1080p, falling to 62 FPS at 1440p, and bottoming out at 37 FPS at 4K. This is a 31% drop followed by a 40% drop, again mirroring the scaling of other settings. The consistency of these percentage drops across all four quality presets confirms that the game's performance scaling is dominated by the resolution itself rather than the individual graphics settings. The 4K Ultra result of 37 FPS is the only point in the measured data that falls below the 40 FPS threshold, indicating a significant strain on the hardware at maximum load.

CPU Role

The AMD Ryzen 5 7500F is a 6-core, 12-thread processor based on the Zen 4 architecture, and its performance characteristics are central to understanding Rust's behavior. The CPU has a base clock of 3.70 GHz and a boost clock of 5.00 GHz, giving it substantial headroom for single-threaded tasks. In the benchmark data, the CPU scores 974 in the 3dmark_single_thread test and 22799 in cinebench_r23_multicore. These scores underscore a processor that is strong in both single and multi-threaded workloads, which is beneficial for Rust's complex simulation and physics.

The performance data suggests the CPU is the primary driver of FPS at 1080p. The 209 FPS result at Low settings is a high number that likely saturates the game's main thread. The game is known for being CPU-intensive, particularly with regards to server-side calculations and entity updates. The Ryzen 5 7500F's high boost clock of 5.00 GHz is critical here, as it allows the processor to quickly process the game's simulation loop. The 32 MB of shared L3 cache is also likely beneficial, as Rust's code can be cache-heavy with many objects and entities.

The CPU's role diminishes as resolution increases. At 4K, the GPU becomes the primary bottleneck, and the 7500F's performance is sufficient to keep up with the graphics card. The drop from 209 FPS at 1080p to 85 FPS at 4K at Low settings is a 59% reduction, which is much steeper than the 31% reduction seen from 1080p to 1440p. This indicates that the GPU's fill rate is the limiting factor at 4K, not the CPU. The CPU's strong single-thread and multi-thread scores from the benchmark data support this interpretation, as it is not a weak point in the system.

The benchmark results also show that the Ryzen 5 7500F performs at the 77th percentile of all CPUs, with an average benchmark score of 24964. Its nearest rivals, the Intel Core i7-11850H and AMD Ryzen 5 8400F, have average scores within 0.2% of the 7500F, confirming that the CPU's processing power is on par with these alternatives. For Rust, this means the 7500F provides a strong foundation for high frame rates at lower resolutions, but its performance is less important when the GPU is the limiting factor.

GPU Role

The AMD Radeon RX 6800 XT is a high-end GPU based on the RDNA 2.0 architecture, and its specifications play a crucial role in the game's performance at higher resolutions. The card features 16 GB of GDDR6 memory on a 256-bit bus, providing a 512.0 GB/s memory bandwidth. With a base clock of 1825 MHz and a boost clock of 2250 MHz, the GPU is well-equipped for demanding titles. Its 4608 shading units and 128 ROPs contribute to a pixel rate of 288.0 GPixel/s and a texture rate of 648.0 GTexel/s.

The GPU's performance is the primary bottleneck at 4K resolutions. The data shows that at 4K, the FPS is significantly lower than at 1080p, which is a classic indicator of GPU limitation. The RX 6800 XT's 16 GB of VRAM is a strong asset for Rust, which has large textures and assets, especially at higher settings. The memory bandwidth of 512.0 GB/s helps to feed the GPU with data, but at 4K Ultra, the card still only manages 37 FPS. This suggests that the GPU's raw compute power is the limiting factor, not its memory.

The RX 6800 XT's 85th percentile ranking among all GPUs, with an average benchmark score of 48477, confirms its position as a high-end card. Its nearest rivals, including the NVIDIA RTX A1000 Mobile and the Intel Arc A550M, have average scores within 3% of the 6800 XT, indicating that it performs as expected for its class. The GPU's DirectX 12 Ultimate support is also beneficial, as Rust's engine can leverage modern rendering features.

The GPU's role is most evident when comparing the FPS at 1440p and 4K. At 1440p, the system achieves 82 FPS at High settings, but at 4K, it drops to 48 FPS. This 41% reduction is a result of the GPU, which is responsible for rendering the increased pixel count. The GPU's 16 GB of VRAM is not likely a limiting factor, as the game can fit its assets within this capacity. However, the GPU's compute and memory bandwidth are the primary constraints at high resolutions.
