Rust

This PC pairing of the AMD Ryzen 5 5500 and the AMD Radeon RX 7900 XT delivers a wide spread of frame rates in Rust, ranging from a demanding 41.2 FPS at 4K Ultra to a fluid 178.1 FPS at 1080p Low. The measured data reveals a system that is heavily influenced by both resolution and preset, with the GPU’s raw power becoming the limiting factor only at the highest pixel counts. At lower resolutions, the CPU’s six Zen 3 cores are pushed hard, yet the combination still manages to clear the 60 FPS playable threshold in nearly every configuration tested.

Measured FPS Breakdown

At 1920x1080, the data shows a consistently high level of performance across all presets. The Low preset yields an average of 178.1 FPS, which is the highest figure recorded for this combo in any scenario. Moving to Medium, the average drops to 152.7 FPS, a decrease of roughly 14% from Low. The High preset further reduces the average to 135.6 FPS. The most demanding setting, Ultra, still produces a very playable 106 FPS average. The scaling here is smooth, with each preset step costing a measurable but not drastic amount of performance. The gap between Low and Ultra is 72.1 FPS, which represents a 40.5% reduction in frame rate when maxing out the visual fidelity at 1080p.

Stepping up to 2560x1440, the frame rates remain high but show a more pronounced impact from the increased pixel count. The Low preset averages 159.4 FPS, still far above the playable threshold. Medium settings deliver 112.5 FPS, while High produces 95.1 FPS. The Ultra preset at this resolution averages 71.3 FPS, which is the lowest figure that still clears the 60 FPS mark. The performance drop from 1080p to 1440p is significant; for example, the Ultra preset loses 34.7 FPS when moving from 1920x1080 to 2560x1440. This indicates that the GPU is beginning to feel the load, but the Ryzen 5 5500 still manages to feed it enough data to maintain high frame rates.

At 3840x2160, the situation changes dramatically. The Low preset is the only configuration that provides a large margin of comfort, averaging 97.1 FPS. The Medium preset drops to 63.9 FPS, barely clearing the 60 FPS threshold. High settings fall below playable at 56 FPS, and Ultra is the most demanding, yielding just 41.2 FPS. The scaling at 4K is steep; the jump from Low to Medium costs 33.2 FPS, and the jump from Medium to High costs another 7.9 FPS. The data clearly shows that 4K is the breaking point for this combo, with only the two lowest presets maintaining the minimum playable frame rate.

CPU and GPU Roles

The benchmark results indicate a clear division of labor that shifts with resolution. At 1920x1080, the CPU is the dominant factor. The Ryzen 5 5500, with its 6 cores and 12 threads, has to work hard to keep up with the RX 7900 XT’s immense rasterization power. The evidence for this is the relatively small difference between presets at 1080p; the GPU is so strong that even at Ultra, it is waiting on the CPU to deliver draw calls and game logic. The 178.1 FPS at Low suggests a CPU-bound ceiling, as increasing graphical load from Low to Medium only reduces the frame rate by 25.4 FPS, which is less than the proportional increase in GPU work.

At 2560x1440, the balance shifts toward the GPU, but the CPU still plays a substantial role. The frame rate drop from 1080p is noticeable, but the system remains largely responsive to preset changes. The Ultra preset at 1440p averages 71.3 FPS, which is a 32.6% reduction from the 106 FPS at 1080p Ultra. This indicates that the GPU is now the primary bottleneck, as the extra pixels are consuming the RX 7900 XT’s fill rate and memory bandwidth. The CPU, while still important, has enough headroom to maintain a steady feed of frames, as evidenced by the fact that the Low preset still hits 159.4 FPS.

At 3840x2160, the GPU is unequivocally the limiting component. The RX 7900 XT’s 20 GB of GDDR6 memory and 800.0 GB/s bandwidth are taxed heavily by the 8.3 million pixels at 4K. The CPU’s role diminishes, as the GPU can no longer produce frames fast enough to saturate even the Ryzen 5 5500’s moderate single-thread performance. The steep drop from Low to Medium at 4K, and the subsequent fall below 60 FPS at High, confirms that the GPU is overwhelmed. The data implies that upgrading the CPU would yield no benefit at 4K, while upgrading the GPU would be the only path to higher frame rates at this resolution.

How This Combo Ranks

The combination of the AMD Ryzen 5 5500 and the AMD Radeon RX 7900 XT ranks 770th out of 3723 tested combos in Rust. This places the system in the top 20.7% of all configurations tested for this game. Given that the GPU is a high-end RDNA 3.0 part, the rank is likely held back by the CPU, which is a mid-range Zen 3 processor. The 770th position suggests that many other pairings with stronger CPUs achieve higher frame rates, particularly at lower resolutions where the CPU matters more. The RX 7900 XT’s 55th percentile ranking among all GPUs indicates it is a capable part, but the Ryzen 5 5500’s 73rd percentile among CPUs shows it is a more modest performer. The combo’s rank reflects the mismatch between these two components, with the CPU dragging down the overall experience in CPU-bound scenarios.

Similar Performance Alternatives

Looking at the nearest rivals for the CPU, the AMD Ryzen 5 5500 performs similarly to several other processors. The AMD Ryzen AI 5 430 has an average score 0.1% lower, making it virtually identical in overall compute capability. The Intel Core i5-12500 scores 0.4% higher, while the Intel Core i7-10700F scores 0.5% lower. The Intel Core i5-11600KF is 0.7% faster. These CPUs would likely produce very similar frame rates in Rust when paired with the RX 7900 XT, with differences of less than 1% in synthetic benchmarks translating to negligible real-world FPS changes.

For the GPU, the nearest rivals are more varied, but the performance deltas are small. The AMD Radeon 660M has an average score 0.5% lower than the RX 7900 XT, which is surprising given the vast difference in memory and architecture. The NVIDIA RTX A2000 Mobile is also 0.5% lower. The AMD Radeon RX 570X is 0.9% lower, while the AMD Radeon RX 9070 XT is 1.5% higher. These figures suggest that in the specific benchmark used for comparison, the RX 7900 XT sits in a tightly packed cluster. However, in real-world gaming, the RX 7900 XT’s 20 GB of VRAM and 800.0 GB/s bandwidth would provide a significant advantage over these rivals, particularly at higher resolutions.

The Verdict

The data clearly shows that this PC can run Rust, but the playable experience depends heavily on the chosen resolution. At 1920x1080, every preset from Low to Ultra clears the 60 FPS threshold, with the Ultra preset averaging 106 FPS. This makes 1080p a fully playable experience with no compromises. At 2560x1440, the system also clears 60 FPS on all presets, including Ultra at 71.3 FPS. This resolution offers a good balance of visual fidelity and performance. At 3840x2160, the system is only playable on Low and Medium presets, with the Medium preset just barely clearing the threshold at 63.9 FPS. The High and Ultra presets fall below 60 FPS, making them unsuitable for smooth gameplay. The verdict is that this is a capable 1080p and 1440p machine for Rust, but 4K gaming requires reducing settings to maintain playability.
