FAQ

Q: What is the average frame rate at 1080p with Ultra settings?

A: At 1920x1080 with Ultra settings, the combination produces an average of 89.7 FPS. This is the most demanding preset at this resolution, and the frame rate is still well within the range of high refresh rate monitors.

Q: How much faster is 1080p Low compared to 4K Ultra?

A: The difference is substantial. The 1080p Low preset achieves an average of 156 FPS, which is 3.9 times higher than the 40.1 FPS average seen at 3840x2160 with Ultra settings. This highlights the massive performance swing between the lowest and highest workload scenarios.

Q: Does the GPU's 16 GB of VRAM provide an advantage in Rust?

A: The AMD Radeon RX 6800 XT features 16 GB of GDDR6 memory with a 512.0 GB/s memory bandwidth. While the measured data does not show VRAM capacity being a limiting factor, the large frame buffer and high bandwidth ensure that texture streaming and asset loading at higher resolutions do not become a bottleneck, as evidenced by playable frame rates at 4K.

Q: What is the combo's overall rank among all tested systems?

A: This specific combination of the Ryzen 7 3700X and RX 6800 XT holds a rank of 617 out of 1717 tested combos in Rust. This places it in the upper-middle tier of all configurations benchmarked for this game.

Q: How does the frame rate scale from 1440p to 4K at High settings?

A: Moving from 2560x1440 to 3840x2160 at High settings drops the average frame rate from 81 FPS to 46 FPS, a reduction of 43%. This indicates that the GPU is the primary constraint at 4K, as the workload increases significantly with pixel count.

Q: Is the CPU or GPU more likely to be the limiting factor at 1080p Low?

A: At 1080p Low, the average frame rate is 156 FPS. The Ryzen 7 3700X has 8 cores and 16 threads with a boost clock of 4.40 GHz, which provides ample headroom. The data suggests that at this low-resolution, high-frame-rate setting, the CPU is the primary focus, as the GPU can render frames faster than the processor can feed it.

GPU Role

The AMD Radeon RX 6800 XT is a high-end graphics card based on the RDNA 2.0 architecture. With a boost clock of 2250 MHz and a game clock of 2015 MHz, it is designed to handle demanding titles. The 16 GB of GDDR6 memory on a 256-bit bus provides a substantial 512.0 GB/s of bandwidth, which is a critical asset for a game like Rust that features large, persistent worlds with many entities.

The GPU's performance is clearly demonstrated in the scaling of frame rates across presets. At any given resolution, the difference between Low and Ultra settings is significant. At 1080p, frame rates range from 156 FPS on Low to 89.7 FPS on Ultra. This range shows that the RX 6800 XT has enough raw power to push very high frame rates when the graphical load is lightened, and it still manages a very playable 89.7 FPS when all effects are maxed out at 1080p. Even at 1440p, the Ultra preset holds an average of 64.8 FPS, demonstrating the card's capability beyond 1080p.

At 4K, the GPU is under maximum stress. The average frame rate at 3840x2160 drops to 46 FPS on High and 40.1 FPS on Ultra. These figures are still playable, but they indicate that the RX 6800 XT is operating at its performance ceiling for this title at this resolution. The benchmark results suggest that the card's 20.74 TFLOPS of FP32 compute power and 288.0 GPixel/s pixel rate are being fully utilized, providing a solid, if not high-refresh-rate, 4K experience.

Resolution Scaling

The performance degradation from 1080p to 4K is steep and consistent across all settings, which is expected for a graphically intensive title. Looking at the High preset, the average frame rate falls from 120.8 FPS at 1920x1080 to 81 FPS at 2560x1440, and then down to 46 FPS at 3840x2160. This represents a 33% drop from 1080p to 1440p and a subsequent 43% drop from 1440p to 4K.

This scaling pattern reveals that the limiting component changes with resolution. At 1080p, the frame rates are exceptionally high (156 FPS on Low, 120.8 FPS on High). The gap between Low and Ultra at 1080p is 66.3 FPS, showing that the GPU is capable of handling the extra work without the CPU becoming a hard bottleneck. However, the fact that the frame rate does not scale perfectly with resolution indicates that the CPU is contributing to the performance ceiling.

As resolution increases to 4K, the GPU becomes the definitive limiting factor. The massive increase in pixel count demands more from the Radeon RX 6800 XT's shading units and memory bandwidth. The 46 FPS average at 4K High is a 62% reduction from the 1080p High score. This shows that the GPU's compute and memory resources are saturated, effectively capping performance. The data indicates that for this combination, 1440p is the sweet spot for balancing visual fidelity with high frame rates, while 4K is viable for a smoother, more cinematic experience rather than competitive play.

How This Combo Ranks

The AMD Ryzen 7 3700X and Radeon RX 6800 XT combination is ranked 617th out of 1717 tested combos in Rust. This places the system in the 64th percentile of all configurations, indicating that it outperforms a majority of systems tested for this specific game. This ranking reflects the strength of both components, as Rust is known to be sensitive to both CPU and GPU performance.

The CPU itself, the Ryzen 7 3700X, is a strong performer. It holds an 85th percentile ranking against all CPUs, with an average benchmark score of 28631. Its nearest rival, the Intel Core i5-12600, has a nearly identical average score of 28654, with a delta of -0.1%. This places the 3700X in a highly competitive tier of processors, where performance differences are marginal. This high CPU standing helps secure a good overall combo rank, as the processor is able to keep up with the demands of the game.

The GPU also contributes positively to the combo's ranking. The Radeon RX 6800 XT has an 87th percentile ranking against all GPUs. Its nearest rival is the Intel Arc A550M, with a delta of 0.5%, followed closely by the NVIDIA RTX A1000, which is 1.7% faster. This indicates that the GPU is a top-tier performer. The combination of an upper-tier CPU and a high-tier GPU results in a system that is well-positioned to deliver a smooth experience in Rust, as confirmed by its 617th place ranking.

CPU Role

The AMD Ryzen 7 3700X is a Zen 2 architecture processor with 8 cores and 16 threads, a base clock of 3.60 GHz, and a boost clock of 4.40 GHz. This configuration is well-suited for Rust, which can utilize multiple threads for physics, entity updates, and server-side simulation. The 32 MB of L3 cache and the 51.2 GB/s memory bandwidth provide the data throughput necessary to feed the RX 6800 XT at high frame rates.

The CPU's impact on the game's performance is most evident at lower resolutions. At 1080p, the frame rates are very high, with the Low preset averaging 156 FPS. At this level, the GPU is not the primary constraint; instead, the CPU's ability to process game logic and issue draw calls becomes the determining factor. The 3700X's high single-thread performance, as indicated by its Cinebench R23 single-core score of 2694, is crucial here. This allows it to handle the main game thread efficiently, preventing it from becoming a severe bottleneck.

This is further supported by the CPU's benchmark scores. The multi-core performance is strong, with a Cinebench R23 score of 19087 and a 3DMark Steel Nomad DX12 score of 3689 from the GPU. The passmark_multithread score of 22458 shows that the CPU can handle significant parallel workloads. While the data does not isolate CPU-bound scenarios definitively, the fact that the frame rate at 1080p Low (156 FPS) is only 16% higher than at 1080p High (120.8 FPS) suggests that the CPU is beginning to limit the maximum frame rate. The Ryzen 7 3700X is a capable partner for the RX 6800 XT, ensuring that the system is not severely imbalanced, though a more powerful CPU might unlock even higher frame rates in the least demanding settings.
