Rust

The AMD Ryzen 7 3700X paired with the AMD Radeon RX 6700 XT delivers a distinctly resolution-dependent experience in Rust. The gap between 1080p and 4K performance is dramatic, and the data shows that the GPU becomes the primary bottleneck as pixel count climbs, while the CPU holds its own at lower resolutions.

Resolution Scaling

The measured FPS shows an aggressive drop as resolution increases from 1920x1080 to 3840x2160. At Low settings, the combo delivers 156.6 FPS at 1080p, which falls to 115.3 FPS at 1440p, and further down to 69.8 FPS at 4K. That represents a 55.4% reduction in frame rate from 1080p to 4K, a stark indicator that the rendering load scales heavily with pixel count.

At Ultra settings, the scaling curve is even more telling. The system manages 70.6 FPS at 1080p, drops to 50.3 FPS at 1440p, and bottoms out at 30.9 FPS at 4K. The 4K Ultra result is less than half of the 1080p Ultra figure, which strongly suggests the RX 6700 XT is saturated by the combination of high detail and dense pixel output. The GPU's 12 GB of GDDR6 memory and 384.0 GB/s bandwidth are clearly being taxed at the higher end.

The intermediate presets tell a consistent story. At Medium settings, the frame rate falls from 109.4 FPS at 1080p to 76.9 FPS at 1440p, then to 48.2 FPS at 4K. High settings show a similar pattern: 94.1 FPS at 1080p, 65.7 FPS at 1440p, and 35.4 FPS at 4K. In every preset, the step from 1440p to 4K costs more than the step from 1080p to 1440p, which indicates that the GPU's fill rate and memory bandwidth are the limiting factors at the top resolution.

Notably, the difference between the Low preset at 4K (69.8 FPS) and the Ultra preset at 1080p (70.6 FPS) is nearly identical. This suggests that the system can achieve similar frame rates either by lowering resolution while keeping high detail, or by keeping resolution high but dropping visual quality. The scaling behavior points to a balanced pairing where neither component completely dominates, but the GPU's limits become visible at 4K with higher presets.

GPU Role

The AMD Radeon RX 6700 XT is built on the RDNA 2.0 architecture with a Navi 22 chip fabricated on a 7 nm process. Its clock speeds are notably high for the generation: a base clock of 2321 MHz, a game clock of 2424 MHz, and a boost clock of 2581 MHz. These clocks translate to a pixel rate of 165.2 GPixel/s and a texture rate of 413.0 GTexel/s, figures that directly influence how quickly Rust's surfaces and geometry are processed.

The GPU's memory subsystem is a critical factor in Rust, a game known for large, persistent worlds. The 12 GB frame buffer is paired with a 192-bit bus, yielding 384.0 GB/s of bandwidth. The measured results suggest that this bandwidth is sufficient for 1080p and 1440p play across all presets, but the 4K figures hint at memory pressure. The gap between 4K Low (69.8 FPS) and 4K Medium (48.2 FPS) is 21.6 FPS, a steep penalty for just one preset step, which is consistent with the GPU's shader and memory resources being pushed past their comfort zone.

The GPU's raw compute capability is rated at 13.21 TFLOPS FP32, with 2560 shading units and 64 ROPs. These specifications align with the measured performance at 1440p, where the card holds above 50 FPS even at Ultra. The 4K Ultra result of 30.9 FPS is the only measurement that falls below 35 FPS, indicating that the card's limits are clearly defined at that extreme.

In the broader benchmark landscape, the RX 6700 XT sits at the 77th percentile among all GPUs. Its nearest rivals include the AMD Radeon RX 6800, which scores 0.7% higher on average, and the NVIDIA RTX A5000, which trails by 1.3%. The data shows this GPU is competitive within its class, and Rust's results reflect that positioning—strong at mainstream resolutions, but not a 4K powerhouse.

How This Combo Ranks

The combination of the Ryzen 7 3700X and RX 6700 XT ranks 927th out of 1717 tested combos in Rust. That places it in the lower-middle portion of the database, which is a meaningful context for the measured frame rates. While the absolute FPS numbers at 1080p are solid, the combo's relative standing suggests that many other pairings achieve higher performance in this title.

The CPU itself holds an 85th percentile ranking among all processors, with an average benchmark score of 28631. Its nearest rivals are tightly grouped: the Intel Core i5-12600 scores 28654 (0.1% higher), the Intel Core i5-12600H scores 28666 (0.1% higher), and the AMD Ryzen 5 5600XT scores 28591 (0.1% lower). This clustering indicates that the 3700X is right in the middle of a competitive pack, and the Rust results reflect that—the CPU is not a standout contributor nor a clear bottleneck.

The GPU, at the 77th percentile, is relatively stronger than the CPU's 85th percentile would suggest in isolation. However, the combo rank of 927 out of 1717 indicates that the pairing does not punch above its weight in Rust specifically. The game's performance appears to be more dependent on GPU capability than CPU muscle, given that the frame rates scale heavily with resolution and preset changes.

When compared to the GPU's nearest rivals, the RX 6700 XT's performance in Rust is consistent with its average scores. The RX 6800, which averages 0.7% higher, would likely produce slightly better frame rates in the same CPU pairing, while the RX 480, which averages 1% lower, would likely trail. The rank position suggests that this combo is a mid-pack performer, adequate for smooth play at 1080p and 1440p, but not competitive with top-tier configurations.

Settings Recommendations

For 1080p gaming, the data clearly shows that the Low preset delivers the highest frame rate at 156.6 FPS, which is ideal for competitive play or high-refresh-rate monitors. However, the Medium preset at 109.4 FPS still provides a very playable experience with better visual quality, and the High preset at 94.1 FPS remains smooth. The Ultra preset at 70.6 FPS is the only 1080p option that dips below 90 FPS, but it is still perfectly playable for most users.

At 1440p, the recommendations shift. The Low preset at 115.3 FPS is excellent for fast-paced action, but the Medium preset at 76.9 FPS offers a better balance of visuals and performance. The High preset at 65.7 FPS is still playable, while the Ultra preset at 50.3 FPS is borderline for a game where quick reactions matter. For most users at this resolution, Medium or High would be the sweet spot.

For 4K gaming, the choices are more constrained. The Low preset at 69.8 FPS is the only option that clears 60 FPS, making it the recommended choice for playable performance. The Medium preset at 48.2 FPS is playable but not ideal, and the High preset at 35.4 FPS and Ultra at 30.9 FPS are both below the threshold for smooth gameplay. Given these measurements, 4K users should stick to Low or Medium settings.

Across all resolutions, the Medium preset provides the most consistent experience relative to visual quality. The frame rate drop from Low to Medium is 47.2 FPS at 1080p, 38.4 FPS at 1440p, and 21.6 FPS at 4K—a diminishing penalty as resolution rises. The jump from Medium to High costs 15.3 FPS at 1080p, 11.2 FPS at 1440p, and 12.8 FPS at 4K, which is a smaller relative penalty. The Ultra preset carries the heaviest cost, especially at 4K.

Measured FPS Breakdown

At 1920x1080, the measurements are as follows: Low settings produce an average of 156.6 FPS, Medium produces 109.4 FPS, High produces 94.1 FPS, and Ultra produces 70.6 FPS. The spread from Low to Ultra is 86.0 FPS, showing a wide range of performance depending on visual fidelity.

At 2560x1440, the results are: Low at 115.3 FPS, Medium at 76.9 FPS, High at 65.7 FPS, and Ultra at 50.3 FPS. The spread narrows to 65.0 FPS, indicating that the GPU's limits become more pronounced at this resolution.

At 3840x2160, the figures fall further: Low at 69.8 FPS, Medium at 48.2 FPS, High at 35.4 FPS, and Ultra at 30.9 FPS. The spread is just 38.9 FPS, which demonstrates that at 4K, even the lowest preset cannot achieve the frame rates seen at higher resolutions.

The data shows a consistent pattern: each preset step at 1080p costs roughly 20-35 FPS, while at 4K the same steps cost only 10-20 FPS. This compression at higher resolutions is a classic sign of GPU bottlenecking. The CPU, with its 8 cores and 16 threads based on Zen 2 architecture, is clearly capable of feeding the GPU at 1080p, but at 4K the GPU's pixel throughput becomes the limiting factor.

The best measured result in the entire dataset is 156.6 FPS at 1080p Low, while the worst is 30.9 FPS at 4K Ultra. The ratio between these extremes is slightly over 5:1, which highlights the wide operating envelope of this combo. For users seeking maximum frame rates, the 1080p Low setting is the clear winner, while those prioritizing visual quality at 4K will face significant performance compromises.
