Rust

The AMD Ryzen 5 7500F paired with the NVIDIA GeForce RTX 4080 SUPER delivers a compelling Rust experience, but the data reveals a system where the CPU and GPU trade dominance depending on the resolution and settings. This analysis breaks down the measured FPS across 12 distinct configurations, placing the results in the context of the broader hardware landscape.

Resolution Scaling

The most striking pattern in the measured data is how the framerate penalty for moving from 1440p to 4K is far steeper than the drop from 1080p to 1440p. At High settings, the average FPS falls from 161.1 at 1080p to 113.3 at 1440p, a reduction of 47.8 FPS. However, the jump from 1440p to 4K at High settings cuts performance from 113.3 down to 63.8 FPS, a loss of 49.5 FPS. This indicates that at 4K, the RTX 4080 SUPER's rendering workload becomes the dominant constraint, as the pixel count overwhelms the GPU's capabilities.

The scaling at Low settings is even more revealing. At 1080p Low, the combo achieves 225.3 FPS, which drops to 195.1 at 1440p and then plummets to 116.0 at 4K. The 4K Low result is 109.3 FPS lower than the 1080p Low figure. This dramatic falloff when the resolution increases while the graphical load is minimized suggests that the GPU's raw throughput is the primary limiter at 4K, regardless of the preset. In contrast, the 1080p to 1440p transition at Low settings shows only a 30.2 FPS drop, indicating that the CPU is still able to feed the GPU adequately at these resolutions.

The data implies that the 1080p and 1440p results are where the Ryzen 5 7500F's influence is most felt, as the GPU has enough headroom to be bottlenecked by the CPU's instruction throughput. At 4K, the GPU's pixel and texture processing limits take over. The Ultra preset at 1440p (88.0 FPS) is notably closer to the 4K High result (63.8 FPS) than to the 1080p Ultra result (121.2 FPS), further confirming that the GPU is the scaling bottleneck as the workload becomes more intensive.

CPU Role

The Ryzen 5 7500F is a 6-core, 12-thread processor based on the Zen 4 architecture, with a base clock of 3.70 GHz and a boost clock of 5.00 GHz. Its benchmark scores show a strong single-threaded performance, with a 3dmark_single_thread score of 974 and a passmark_single_thread score of 3841. In a game like Rust, which is known for its simulation and entity-heavy server logic, this single-thread strength is critical.

The CPU's performance in the measured FPS data is most apparent at 1080p Low, where the average of 225.3 FPS is the highest of any configuration. This high framerate suggests that the CPU is capable of driving the game engine to its limits when the GPU is not overburdened. The Cinebench R23 multicore score of 22799 and the 3dmark_max_threads score of 6379 indicate that the 6-core design can handle multithreaded workloads, but the game's reliance on single-thread performance is likely why the 1080p results are so high.

Comparing the CPU to its nearest rivals, the Ryzen 5 7500F's avgBenchmarkScore of 24993 is nearly identical to the Intel Core i7-11850H (24974, deltaPct 0.1) and the AMD Ryzen 9 6900HX (24897, deltaPct 0.4). The data suggests that for Rust's CPU-bound scenarios, this processor provides a level of performance that is competitive with these alternatives, despite having fewer cores than some. The L3 cache of 32 MB shared is a significant asset for a game that often deals with large world data, likely helping to maintain the high average FPS seen at lower resolutions.

The CPU's boost clock of 5.00 GHz is a key factor in the 1080p results. When the graphical load is light, the processor can sustain higher frequencies, and the measured FPS reflects this. The 1080p Medium result of 192.1 FPS, which is higher than the 1440p High result of 113.3 FPS, shows that the CPU is not the limiting factor until the GPU's workload increases.

GPU Role

The NVIDIA GeForce RTX 4080 SUPER features 16 GB of GDDR6X memory on a 256-bit bus, delivering a bandwidth of 736.3 GB/s. Its boost clock of 2550 MHz and 52.22 TFLOPS of FP32 performance are substantial, but the measured data shows that this is not always enough to maintain high framerates at 4K. The 4K Ultra average of 49.2 FPS is the lowest of all configurations, indicating that even this powerful GPU struggles with the most demanding settings at the highest resolution.

The GPU's role as the bottleneck at 4K is clear when looking at the scaling from High to Ultra at that resolution. The 4K High average of 63.8 FPS drops by 14.6 FPS to 49.2 FPS at Ultra, a 23% reduction. This is a stark contrast to the 1080p results, where the drop from High (161.1) to Ultra (121.2) is a 39.9 FPS difference, but the absolute framerates are still playable. The 16 GB VRAM capacity is likely sufficient for Rust at these settings, but the GPU's compute units are saturated at 4K.

The RTX 4080 SUPER's percentileVsAllGpus of 88 and its avgBenchmarkScore of 53610 place it slightly ahead of the AMD Radeon RX 6900 XT (53489, deltaPct 0.2) in synthetic benchmarks. However, the measured FPS in Rust shows that the GPU's performance is heavily dependent on the resolution. The 1440p Low result of 195.1 FPS demonstrates that the GPU can deliver high framerates when the CPU is not the bottleneck, but the 4K Low result of 116.0 FPS shows a significant drop that is attributable to the GPU's pixel throughput limits.

The memory clock of 1438 MHz, which translates to 23 Gbps effective, is a crucial specification for a game like Rust that features large, open-world environments. The data indicates that the GPU's memory bandwidth is adequate for 1080p and 1440p, but at 4K, the combination of higher pixel count and complex shaders begins to exceed what the RTX 4080 SUPER can deliver in real-time.

How This Combo Ranks

This particular combination of the Ryzen 5 7500F and RTX 4080 SUPER ranks 93rd out of 1717 tested combos in Rust. This percentile placement of roughly the top 5.4% indicates that this is a high-performing pairing for the game. The rank is likely boosted by the CPU's strong single-threaded performance, which is critical for Rust's server-side simulation, and the GPU's ability to handle high resolutions.

The rank of 93 out of 1717 suggests that while there are many combinations that perform better, this setup is in the upper echelon. The data shows that the combo is capable of exceeding 200 FPS at 1080p Low (225.3 FPS) and 195.1 FPS at 1440p Low, which are excellent results for competitive play. However, the 4K Ultra result of 49.2 FPS is below the 60 FPS threshold, which would put this combo in a lower tier for that specific configuration.

The combination's rank reflects the balance between the CPU and GPU. The Ryzen 5 7500F's 5.00 GHz boost clock and the RTX 4080 SUPER's 2550 MHz boost clock work together to deliver high average FPS in most scenarios. The fact that the combo ranks 93rd out of 1717, despite the GPU being end-of-life, suggests that the CPU's contribution is significant in Rust's engine.

Settings Recommendations

Based on the measured FPS data, the optimal preset depends heavily on the user's target resolution and framerate. For 1920x1080, the Medium preset offers an average of 192.1 FPS, which is a significant improvement over the High preset's 161.1 FPS while still maintaining visual quality. The 1080p Ultra preset provides 121.2 FPS, which is still smooth, but the jump from Medium to Ultra costs 70.9 FPS, making Medium the most efficient choice for high-refresh-rate monitors.

At 2560x1440, the High preset delivers a solid 113.3 FPS, which is ideal for 144Hz displays. The Medium preset at 1440p yields 130.5 FPS, but the visual fidelity is lower. For users prioritizing framerate over visuals, Low at 1440p offers 195.1 FPS, but this may compromise the game's visual clarity. The Ultra preset at 1440p (88.0 FPS) is still playable, but it does not offer a substantial visual improvement over High to justify the 25.3 FPS loss.

For 3840x2160, the data suggests that High settings (63.8 FPS) is the recommended choice, as it is the only 4K preset that maintains an average above 60 FPS. The Medium preset at 4K (78.4 FPS) is also viable, but the Low preset (116.0 FPS) sacrifices too much visual quality. The 4K Ultra preset at 49.2 FPS should be avoided for a smooth experience. The best overall experience across all resolutions is achieved by using Medium at 1080p or High at 1440p, balancing the GPU load and CPU capability.
