Rust

Rust is a survival game that stresses both CPU and GPU, and the pairing of the AMD Ryzen 7 7800X3D with the AMD Radeon RX 7800 XT produces a wide range of frame rates depending on resolution and quality settings. The measured data below provides a clear picture of how this combination behaves across 1080p, 1440p, and 4K, and where the performance limits lie.

Resolution Scaling

At Low settings, the average FPS at 1920x1080 is 201.8, dropping to 140.9 at 2560x1440 and 82.4 at 3840x2160. This pattern shows a substantial reduction as pixel count increases. At High settings, the numbers are 114.6, 80.2, and 47.2 respectively. At Ultra, the frame rates are 89.7, 60, and 32.7. The scaling from 1080p to 1440p is less severe than from 1440p to 4K, indicating that the GPU becomes the primary constraint at higher resolutions. The CPU’s strong single-thread performance, evidenced by a Cinebench R23 single-core score of 4115, is likely sufficient to feed the GPU at lower resolutions, but the GPU’s compute capacity limits the frame rate as resolution climbs. The 4K Ultra result of 32.7 FPS is below the 60 FPS seen at 1440p Ultra, highlighting the difficulty of running Rust at 4K with maximum quality on this hardware.

The gap between Low and Ultra at each resolution is also telling. At 1080p, Low yields 201.8 FPS while Ultra yields 89.7, a difference that shows how much headroom the settings offer. At 1440p, the spread is from 140.9 down to 60, and at 4K it narrows to 82.4 down to 32.7. This compression at higher resolutions suggests that the GPU is already near its limit even at Low settings in 4K, leaving less room for quality improvements. The CPU’s 96 MB of L3 cache and 5.00 GHz boost clock are strong assets for maintaining high frame rates in CPU-bound scenarios, but the data shows that at 4K the GPU is the limiting factor.

GPU Role

The AMD Radeon RX 7800 XT features 16 GB of GDDR6 memory on a 256-bit bus, providing 624.1 GB/s of bandwidth. Its base clock is 1295 MHz, with a boost clock of 2430 MHz and a game clock of 2124 MHz. The memory clock is 2438 MHz, which translates to 19.5 Gbps effective. With 3840 shading units, 240 texture mapping units, and 96 ROPs, the card is built for high-throughput rendering. The 16 GB VRAM is a large pool, and the measured results show that at 4K Ultra, the average FPS is 32.7, indicating that the GPU’s compute power, not its memory capacity, is the limiting factor. The GPU’s average benchmark score is 32619, placing it in the 76th percentile of all GPUs. Its nearest rival, the AMD FirePro S9300 X2, scores 32540, a difference of 0.2%. The high boost clock of 2430 MHz helps maintain performance in demanding scenes, but the 4K results show that even this card cannot sustain high frame rates at maximum quality in Rust.

The memory bandwidth of 624.1 GB/s is substantial, and the 256-bit bus ensures that the 16 GB pool is fed efficiently. At 1080p and 1440p, the GPU’s compute resources are more than enough to keep up with the CPU, as evidenced by the high FPS numbers. However, at 4K, the pixel count overwhelms the shading units and ROPs, causing the frame rate to drop sharply. The 60 FPS at 1440p Ultra is a notable milestone, but the 32.7 FPS at 4K Ultra shows that the card is not designed for 4K max settings in this title. The GPU’s 76th percentile ranking reflects its position as a strong mid-to-high-end card, but Rust’s demands at 4K push it beyond its comfort zone.

The table lists all measured average FPS values. The range across all settings and resolutions spans from 32.7 FPS at 4K Ultra to 201.8 FPS at 1080p Low. The 1080p results are consistently high, with even Ultra staying above 89 FPS. At 1440p, the spread is tighter, with Low at 140.9 and Ultra at exactly 60. At 4K, only Low manages to stay above 60 FPS, while Medium, High, and Ultra all fall below that threshold. This breakdown shows that the combo is well-suited for 1080p and 1440p gaming, but 4K requires significant compromises in quality.

How This Combo Ranks

This combination of CPU and GPU ranks 591 out of 1717 tested combos in Rust. The CPU itself sits in the 87th percentile of all CPUs, with an average benchmark score of 31580. Its nearest rival, the Intel Core i7-12700F, scores 31543, a 0.1% difference. The GPU is in the 76th percentile, with an average score of 32619. The combo rank of 591 places it in the upper portion of the tested field, reflecting the strength of both components. The CPU’s high percentile is driven by its 8 cores, 16 threads, and 96 MB of L3 cache, which are well-suited for gaming workloads. The GPU’s 76th percentile is respectable, though not top-tier, and the combo rank aligns with that positioning.

The CPU’s nearest rivals are all within 0.6% of its average score, indicating a tight cluster of performance. The GPU’s nearest rivals include the AMD FirePro S9300 X2 and NVIDIA P104-100, with deltas of 0.2% and -0.4% respectively. These comparisons show that the CPU is competitive with other high-end processors, while the GPU sits in a mid-to-high tier. The 591st rank out of 1717 means that this combo outperforms a majority of tested configurations, but it is not at the very top. For a 1080p or 1440p gaming rig, this pairing offers a strong balance of CPU and GPU capability.

Settings Recommendations

Based on the measured FPS, the best experience depends on the target resolution. At 1920x1080, even Ultra settings deliver 89.7 FPS, which is smooth for most players. For higher refresh rates, Low settings provide 201.8 FPS, but the visual quality trade-off may not be worth it. At 2560x1440, High settings yield 80.2 FPS, while Ultra drops to exactly 60 FPS. The 60 FPS at Ultra is a solid result, but High offers a comfortable margin. At 3840x2160, only Low settings maintain an average above 60 FPS, with 82.4 FPS. Medium drops to 52.5, and High to 47.2, so Low is the only playable preset for 4K. For a balanced experience, High at 1440p or Low at 4K are the recommended presets.

The data suggests that the sweet spot for this combo is 1440p with High settings, where the frame rate of 80.2 FPS provides a good balance between visual fidelity and responsiveness. If a player prioritizes frame rate over quality, 1080p Low at 201.8 FPS is an option, but the visual downgrade is significant. At 4K, the only viable choice is Low, and even then the 82.4 FPS is not as high as the 1440p results. For those who insist on 4K, the GPU’s 16 GB VRAM is not the bottleneck; rather, the compute power is insufficient for Ultra settings. The measured numbers make it clear that this hardware is best used at 1080p or 1440p, with 4K reserved for Low settings or a future GPU upgrade.
