Rust

The AMD Ryzen 7 9800X3D paired with the AMD Radeon RX 6700 XT delivers a wide spread of performance in Rust, scaling from a highly playable 165.3 FPS at 1080p Low down to a cinematic 26.3 FPS at 4K Ultra. The measured data shows that the combination of this processor's large 96 MB shared L3 cache and the GPU's 12 GB of GDDR6 memory creates a system that is exceptionally responsive at lower resolutions but becomes increasingly constrained as graphical load rises. This analysis breaks down the optimal settings, answers common questions, and contextualizes the hardware's role in this specific survival title.

Settings Recommendations

The benchmark results indicate that the Low preset offers the best balance of fluidity and responsiveness, particularly for players targeting high refresh rates. At 1920x1080, the Low preset achieves an average of 165.3 FPS, which is the highest score recorded across all configurations. This represents a substantial 46% performance uplift over the High preset at the same resolution, which posts an average of 91.5 FPS. The gains are consistent at higher resolutions; at 2560x1440, Low delivers 113.3 FPS compared to 63.4 FPS on High, and even at 3840x2160, Low maintains a playable 70 FPS.

For users with 1440p monitors who prefer visual fidelity over maximum frame rates, the Medium preset is the most sensible choice. It produces an average of 76.2 FPS at 2560x1440, which is a 20% improvement over High’s 63.4 FPS. This suggests that the Medium preset strips away the most demanding effects while retaining enough detail to be visually distinct from Low. The data shows that the jump from Low to Medium costs roughly 37 FPS at 1080p (from 165.3 to 112.9 FPS) and 37.1 FPS at 1440p (from 113.3 to 76.2 FPS), indicating that the added visual features have a consistent and significant cost.

The High and Ultra presets are not recommended for this combination unless the user is prioritizing image quality above all else. At 1080p, High yields 91.5 FPS which is acceptable, but Ultra drops to 70.1 FPS, showing that the step to Ultra incurs a 23% performance penalty over High. The situation worsens at 4K, where High averages just 35.9 FPS and Ultra falls to 26.3 FPS, making both presets effectively unplayable for smooth gameplay. The data suggests that the Ultra preset’s requirements scale poorly with resolution, and the 12 GB VRAM buffer on the RX 6700 XT, while generous, is not enough to prevent severe frame rate drops when combined with the 9800X3D’s rapid draw calls.

FAQ

Q: What is the highest average frame rate achievable with this hardware in Rust?

A: The highest recorded average is 165.3 FPS, achieved at 1920x1080 resolution with the Low settings preset.

Q: How much performance is lost when moving from 1080p to 1440p on the High preset?

A: The data shows a drop from 91.5 FPS at 1920x1080 to 63.4 FPS at 2560x1440, representing a reduction of 28.1 FPS or approximately 31%.

Q: Is the Ultra preset viable at 4K resolution for this system?

A: No. The measured average frame rate at 3840x2160 with Ultra settings is 26.3 FPS, which is below the threshold for smooth, responsive gameplay.

Q: Which settings preset provides the most significant performance advantage over Low at 1440p?

A: The Medium preset is the closest step up, offering 76.2 FPS compared to Low’s 113.3 FPS. The High preset (63.4 FPS) is significantly slower, and Ultra (48.5 FPS) is even more demanding.

Q: Does the CPU’s cache size have a visible impact on the frame rates?

A: The Ryzen 7 9800X3D features a 96 MB shared L3 cache. While the data cannot isolate the cache’s effect, the high frame rates at 1080p Low (165.3 FPS) suggest that the processor is well-equipped to handle the game’s single-threaded tasks without bottlenecking the GPU at lower resolutions.

Q: What is the performance difference between the Low and Ultra presets at 1080p?

A: The Low preset averages 165.3 FPS, while the Ultra preset averages 70.1 FPS. This indicates that Ultra is 95.2 FPS slower, or roughly 58% less performant than Low.

GPU Role

The AMD Radeon RX 6700 XT is the primary driver of visual output, and its specifications directly explain the scaling pattern seen in the measured data. The GPU features 12 GB of GDDR6 memory on a 192-bit bus, providing a bandwidth of 384.0 GB/s. This memory configuration is sufficient for 1080p and 1440p gaming, but the 4K results show its limitations. At 3840x2160, the average frame rate on High is 35.9 FPS, which is a stark contrast to the 91.5 FPS seen at 1920x1080 with the same preset.

The GPU's clock speeds are also a relevant factor. With a base clock of 2321 MHz and a boost clock of 2581 MHz, the RX 6700 XT is capable of high throughput, but the data shows that this compute power is not enough to maintain high frame rates at 4K Ultra. The transition from High to Ultra at 4K results in a drop from 35.9 FPS to 26.3 FPS, a 27% decrease. This suggests that the Ultra preset relies heavily on pixel shader effects and memory bandwidth, both of which are taxed at 3840x2160. The GPU’s FP32 performance of 13.21 TFLOPS is adequate for the 1080p and 1440p results, but the 4K performance indicates that the memory bus width and bandwidth become the limiting factors.

The GPU's performance relative to its peers is solid. The average benchmark score places it near the AMD Radeon RX 6800, which is only 0.7% higher, and ahead of the NVIDIA RTX A5000 by 1.3%. This indicates that while the RX 6700 XT is not a top-tier card, it is well-matched to the Ryzen 7 9800X3D for this game at resolutions up to 1440p. The 12 GB VRAM is a critical asset, as it prevents texture streaming issues that could cause stuttering, but the data shows that it does not overcome the raw compute demands of 4K Ultra.

How This Combo Ranks

The combination of the Ryzen 7 9800X3D and RX 6700 XT ranks 934th out of 1717 tested combos in Rust. This places it in the lower-middle portion of the database, which is surprising given the processor’s high percentile ranking. The CPU itself is in the 90th percentile when compared to all CPUs, with an average benchmark score of 37780, but its nearest rivals include the Intel Core i5-13600KF and Intel Core Ultra 5 225, which have similar average scores.

The GPU is less dominant, sitting in the 77th percentile among all GPUs. This suggests that the processor is far more capable than the graphics card, and the combo’s overall rank is dragged down by the GPU’s performance ceiling. The data shows that the CPU’s single-thread score of 1212 in 3dmark and multi-thread score of 10081 in 3dmark are strong, but these advantages are not fully utilized at higher resolutions where the GPU is the bottleneck. The combo’s rank of 934 indicates that many other pairings with weaker CPUs but stronger GPUs outperform it in Rust, particularly at 1440p and 4K where the GPU’s workload increases.

Comparatively, the CPU’s nearest rivals, such as the Intel Xeon 6353P (0.1% slower) and the Core Ultra 5 225 (0.1% slower), would likely produce similar frame rates when paired with the same GPU, as the limiting factor is the graphics card. This implies that the 9800X3D’s advanced Zen 5 architecture and 96 MB L3 cache are not the primary determinants of the final FPS in this title; instead, the RX 6700 XT’s compute and memory bandwidth dictate the upper limits.

Resolution Scaling

The measured data reveals a clear pattern of frame rate degradation as resolution increases, which is characteristic of a system where the GPU becomes the limiting component. At the Low preset, the average frame rate drops from 165.3 FPS at 1080p to 113.3 FPS at 1440p and 70 FPS at 4K. This represents a 31% drop from 1080p to 1440p and a further 38% drop from 1440p to 4K. The absolute differences are 52 FPS and 43.3 FPS, respectively.

The High preset shows a similar trend. It starts at 91.5 FPS at 1080p, falls to 63.4 FPS at 1440p, and bottoms out at 35.9 FPS at 4K. The relative drops are 31% and 43% for the two resolution steps. This progressive decline indicates that the GPU’s fill rate and memory bandwidth are being saturated. The 4K result on High is particularly telling, as it is below the 60 FPS threshold, suggesting that the RX 6700 XT’s 384.0 GB/s bandwidth is insufficient for the pixel count.

The scaling also shows that the CPU is not the primary bottleneck at higher resolutions. The Ryzen 7 9800X3D’s strong multi-threaded performance (e.g., 34004 in Cinebench R23) is sufficient to feed the GPU at 1080p, but as resolution increases, the GPU’s workload grows, and the frame rate drops accordingly. The fact that the Low preset at 4K (70 FPS) is faster than the High preset at 1440p (63.4 FPS) further underscores that settings have a greater impact on performance than resolution alone. This suggests that users should prioritize lowering settings over reducing resolution to maintain high frame rates, as the GPU is the limiting factor in this pairing.
