Rust

The AMD Ryzen 5 5600 and AMD Radeon RX 6800 XT combination delivers a highly playable Rust experience, with the data showing a clear shift from GPU-bound performance at 4K to a more balanced workload at lower resolutions. The measured FPS indicates that this pairing excels at 1440p, where it achieves a comfortable 82.7 FPS on High settings, while 4K Ultra remains demanding at 34.7 FPS.

Resolution Scaling

The performance drop from 1080p to 4K is substantial, revealing how the RX 6800 XT becomes the limiting factor at higher resolutions. At High settings, the average frame rate falls from 116.9 FPS at 1080p to 82.7 FPS at 1440p, a reduction of 34.2 FPS, and then further down to 46.5 FPS at 4K. This scaling pattern, where 4K High delivers only about 40% of the 1080p High performance, strongly indicates that the GPU is the primary bottleneck when pixel count increases. The data confirms that the 16 GB of GDDR6 memory and the 512.0 GB/s bandwidth are sufficient for 4K, but the raw compute power of the 20.74 TFLOPS FP32 GPU is taxed heavily at that resolution.

At Low settings, the trend is even more pronounced: 191.2 FPS at 1080p drops to 144.6 FPS at 1440p and then to 83.2 FPS at 4K. The 4K Low result is actually higher than 4K High, which shows that reducing graphical load allows the GPU to push more frames, but the gap between 1080p and 4K remains large. This suggests that even at Low settings, the RX 6800 XT’s pixel throughput, rated at 288.0 GPixel/s, is the constraining factor at 4K, while at 1080p the CPU has more room to feed the GPU.

GPU Role

The RX 6800 XT, based on the RDNA 2.0 architecture with a Navi 21 chip, is the dominant component in this pairing for Rust. Its boost clock of 2250 MHz and game clock of 2015 MHz provide the muscle needed for the game’s demanding rendering. The memory configuration, 16 GB of GDDR6 on a 256-bit bus with 512.0 GB/s bandwidth, is ample for Rust’s open-world environments, as evidenced by the 4K High result of 46.5 FPS. However, the data shows that the GPU’s performance ceiling is reached at 4K Ultra, where the average FPS falls to 34.7, a figure that is only 37% of the 1080p Ultra result of 87.6 FPS.

The GPU’s benchmark percentile of 87 versus all GPUs places it in the upper tier, and its average benchmark score of 49982 is 2.6% higher than the NVIDIA GeForce RTX 4070 Ti SUPER, one of its nearest rivals. In Rust specifically, the 4K High result of 46.5 FPS demonstrates that the 20.74 TFLOPS FP32 compute and 128 ROPs are sufficient for 4K gaming at medium-high settings, but not for maxed-out presets. The 72 ray accelerators (RT cores) are present on the chip, but the measured data for Rust does not include ray tracing benchmarks, so their impact on this title cannot be quantified from these numbers.

How This Combo Ranks

This specific CPU-GPU combination ranks 563rd out of 1717 tested combos for Rust, placing it in the 67th percentile of all tested systems. This ranking is respectable, considering the Ryzen 5 5600 is a mid-range 6-core processor from 2022, while the RX 6800 XT is a high-end GPU from 2020. The data shows that the GPU carries most of the weight in this pairing, as the CPU’s own benchmark percentile of 79 versus all CPUs is lower than the GPU’s 87. The combo’s rank of 563 suggests that while it is not a top-tier configuration, it outperforms the majority of tested systems, with the measured FPS confirming this is a capable 1440p gaming machine.

The CPU’s nearest rivals in terms of average benchmark score include the Intel Xeon D-1746TER, which is 0.6% faster, and the AMD EPYC 9554P, which is 0.6% slower. These are server-class processors, which indicates that the Ryzen 5 5600’s gaming performance is competitive with much more expensive hardware in synthetic tests. The GPU’s nearest rival, the Intel Arc A550M, is only 0.5% faster on average, but the RX 6800 XT’s 16 GB VRAM and higher bandwidth give it a clear advantage in a game like Rust that benefits from large textures.

Measured FPS Breakdown

At 1080p, the data shows a clear progression across settings: Low yields 191.2 FPS, Medium 138.6 FPS, High 116.9 FPS, and Ultra 87.6 FPS. The difference between Low and Medium is 52.6 FPS, while the drop from High to Ultra is 29.3 FPS. This indicates that Rust’s Ultra preset is particularly demanding, costing nearly a third of the High preset’s performance. The 1080p Low result of 191.2 FPS is the highest recorded for this combo, suggesting that the CPU, with its 6 cores and 12 threads boosting to 4.40 GHz, is capable of feeding the GPU at high frame rates when graphical load is low.

At 1440p, the averages are 144.6 FPS for Low, 95.4 FPS for Medium, 82.7 FPS for High, and 61.7 FPS for Ultra. The gap between Low and Medium here is 49.2 FPS, which is similar to 1080p, but the overall numbers are lower due to the increased pixel count. The High preset at 1440p produces 82.7 FPS, which is smooth for most players, while Ultra drops to 61.7 FPS, still playable but with a noticeable reduction in fluidity. At 4K, the results are 83.2 FPS for Low, 59.1 FPS for Medium, 46.5 FPS for High, and 34.7 FPS for Ultra. The 4K Low result is surprisingly high, only 0.5 FPS lower than the 1440p High result, which shows that Low settings at 4K can be a viable option for competitive play.

CPU Role

The AMD Ryzen 5 5600, with 6 cores and 12 threads based on the Zen 3 Vermeer architecture, plays a supporting role in this pairing. Its boost clock of 4.40 GHz and 32 MB of shared L3 cache provide adequate single-thread performance for Rust, which is known to be sensitive to CPU speed. The CPU’s Cinebench R23 single-core score of 2584 and multi-core score of 18309 indicate solid performance, but the data shows that it is not the primary bottleneck in most scenarios. At 1080p Low, the 191.2 FPS result suggests the CPU can keep up with the GPU’s output, but at 4K, the frame rates are clearly GPU-limited.

The CPU’s 3DMark single-thread score of 882 and 16-thread score of 5641 show that it scales well with additional threads, but Rust’s engine typically relies on fewer cores. The PassMark single-thread score of 3256 and multi-thread score of 21541 confirm that this processor is a balanced performer. Compared to its nearest rivals, the Intel Core i7-11700F is 0.9% faster on average, but the Ryzen 5 5600’s lower TDP of 65 W gives it an efficiency advantage. The data indicates that the CPU is sufficient for this GPU, as the combo rank of 563 is more reflective of the GPU’s capabilities than any CPU limitation.

Settings Recommendations

Based on the measured FPS, the best experience for this combo is the High preset at 1440p, which delivers 82.7 FPS. This setting balances visual fidelity with performance, providing a smooth frame rate that is well above the 60 FPS threshold. For players with 1080p monitors, the High preset at 116.9 FPS is the clear choice, as it offers excellent visuals without sacrificing responsiveness. The Ultra preset at 1080p yields 87.6 FPS, which is still playable, but the 29.3 FPS penalty compared to High is not worth the marginal visual improvement.

At 4K, the data suggests that Medium settings at 59.1 FPS are the most viable option, as High drops to 46.5 FPS and Ultra falls below 35 FPS. The Low preset at 4K produces 83.2 FPS, which is surprisingly competitive, but the visual quality loss is significant. For competitive play, the Low preset at 1440p, with 144.6 FPS, offers the highest headroom and fastest response times. The Medium preset at 1080p, at 138.6 FPS, is also a strong option for players who want higher frame rates with slightly better visuals than Low.
