Rust

The AMD Ryzen 7 9700X paired with the AMD Radeon RX 6750 XT delivers a varied performance profile in Rust, with the data showing a clear shift in system bottlenecks as resolution and settings change. This analysis breaks down the measured FPS results across the three tested resolutions and four quality presets, interpreting what the numbers indicate about the CPU and GPU roles, and providing actionable settings guidance based solely on the measured data.

Resolution Scaling

The measured FPS data for this combination in Rust reveals a significant drop in performance as resolution increases, which is a classic indicator of the GPU becoming the primary limiting factor at higher pixel counts. At 1080p with Low settings, the system achieves an average of 173 FPS. Moving to 1440p at the same Low preset, the average FPS drops to 119, a reduction of 54 FPS. Pushing further to 4K at Low settings yields an average of 70 FPS, which is just 40% of the 1080p Low figure. This scaling pattern demonstrates that the RX 6750 XT is heavily taxed by the increasing pixel workload, particularly at 4K where the frame rate falls below the 60 FPS threshold.

The scaling behavior under the High preset tells a similar story. At 1080p High, the average is 98 FPS. At 1440p High, that number falls to 68 FPS, and at 4K High, it drops to 40 FPS. The performance penalty from 1440p to 4K is substantial, with the 4K result being less than half of the 1080p result. This steep decline points directly at the GPU as the dominant bottleneck at higher resolutions—the processor has enough headroom to feed frames at 1080p, but the graphics card cannot maintain that throughput when rendering over four times the pixels.

The Ultra preset emphasizes this GPU-bound behavior even more clearly. The system manages 75 FPS at 1080p Ultra, 51 FPS at 1440p Ultra, and just 30 FPS at 4K Ultra. The gap between 1080p and 4K at Ultra settings is a 45 FPS difference, indicating that the most demanding visual settings combined with high resolution overwhelm the 12 GB graphics card. In contrast, the Medium preset shows a more moderate drop, from 116 FPS at 1080p to 80 FPS at 1440p and 47 FPS at 4K, but the same fundamental trend holds: the higher the resolution, the more the GPU constrains performance.

A key observation from the data is that the CPU does not appear to be a significant constraint at any tested resolution. The fact that 1080p Low produces 173 FPS suggests the processor can handle the game's simulation and draw-call overhead without limiting the frame rate. The bottleneck shifts entirely to the GPU as resolution climbs, which is typical for a game like Rust that relies heavily on world rendering and pixel shading. For this combination, users targeting 4K should expect to use Low or Medium settings to approach playable frame rates, while 1440p offers a more balanced experience.

GPU Role

The AMD Radeon RX 6750 XT is the central component in determining this system's performance at higher resolutions, and the measured data confirms its 12 GB of GDDR6 memory is sufficient for the game's demands at the tested settings. The GPU's boost clock of 2600 MHz and game clock of 2495 MHz, paired with a memory bandwidth of 432.0 GB/s, provide the raw throughput needed for Rust's open-world environments, but the frame rates at 4K indicate the card is working at its limits.

The benchmark results for the RX 6750 XT show a 3DMark Steel Nomad DX12 score of 2548, and the GPU sits in the 71st percentile compared to all GPUs. Its average benchmark score of 26011 places it just 0.5% ahead of the AMD Radeon R9 M395X and 1.1% ahead of the NVIDIA GeForce RTX 3080 Ti Mobile in the nearest rivals list. These proximity scores suggest that while the card is competent, it is not a high-end performer, which aligns with the measured 4K results of 40 FPS on High and 30 FPS on Ultra.

The 12 GB VRAM capacity is noteworthy for Rust, a game known for large texture sets and persistent worlds. At 4K Ultra, the system still delivers a playable-in-principle 30 FPS average, which means the memory allocation is not causing a hard failure—the card is simply compute-bound. The pixel rate of 166.4 GPixel/s and texture rate of 416.0 GTexel/s are the specs that matter most here, and the data shows these are insufficient for smooth 4K gameplay at higher presets.

The GPU's FP32 performance of 13.31 TFLOPS is another indicator of its mid-range positioning. At 1440p Medium, the card produces 80 FPS, which is a solid result, but at 4K Medium it falls to 47 FPS. This 33 FPS drop from 1440p to 4K at the same settings shows the GPU's fill-rate limits. The card's end-of-life production status and 250 W TDP suggest it is a last-generation mid-range solution, and the measured data supports that characterization: it handles 1080p and 1440p well but struggles with 4K beyond Low settings.

CPU Role

The AMD Ryzen 7 9700X plays a supporting but important role in this system, and the measured FPS data indicates it is not the primary bottleneck at any tested resolution. With 8 cores and 16 threads, a base clock of 3.80 GHz and a boost clock of 5.50 GHz, this Zen 5 processor provides ample single-thread and multi-thread performance for Rust's simulation-heavy gameplay. The CPU's benchmark scores confirm its strength: a Cinebench R23 multi-core score of 20485 and a single-core score of 2211 place it well above average.

The CPU's percentile ranking of 86th among all CPUs, with an average benchmark score of 37943, shows it is a high-tier processor. Its nearest rivals include the Intel Core i9-14901E, which scores 0.1% higher, and the AMD Ryzen AI 9 HX 370, also 0.1% higher. These negligible differences mean the 9700X is effectively at parity with top competitors in synthetic tests, and the measured game results reflect this: at 1080p Low, the system reaches 173 FPS, which is a frame rate that most games would be CPU-limited at, but here the processor keeps up.

The CPU's 32 MB of shared L3 cache and dual-channel DDR5 memory support with 89.6 GB/s bandwidth are relevant to Rust's performance. The game's procedural world generation and entity updates benefit from high single-thread performance, and the 9700X delivers that with a PassMark single-thread score of 4654. The multi-thread score of 37161 also helps with background tasks and server-side simulation.

Evidence that the CPU is not limiting comes from the scaling pattern: when moving from 1080p Low (173 FPS) to 1440p Low (119 FPS), the frame rate drops proportionally with pixel count, which is a GPU-bound signature. If the CPU were the limiter, the frame rate would stay flat across resolutions. The fact that 4K Low produces 70 FPS—still above the 60 FPS playability threshold—indicates the CPU has enough headroom to feed the GPU even at lower settings where the GPU is less stressed. The 8-core, 16-thread configuration is well-suited for Rust's multi-threaded rendering pipeline, and the data shows no CPU-related frame dips in the measured Medium preset minimums (99 FPS at 1080p, 68 FPS at 1440p, 40 FPS at 4K).

This scaling pattern is characteristic of a GPU-bound scenario, as the CPU's 8-core, 16-thread configuration provides sufficient performance to avoid becoming the bottleneck.

Measured FPS Breakdown

The measured FPS data for this combination in Rust provides a complete picture across three resolutions and four settings presets. At 1920x1080, the system delivers its highest frame rates: Low averages 173 FPS, Medium averages 116 FPS with a minimum of 99 FPS and maximum of 134 FPS, High averages 98 FPS, and Ultra averages 75 FPS. The 1080p results show a clear performance hierarchy, with Low being nearly 2.3 times faster than Ultra.

At 2560x1440, the averages drop but remain playable: Low averages 119 FPS, Medium averages 80 FPS with a minimum of 68 FPS and maximum of 92 FPS, High averages 68 FPS, and Ultra averages 51 FPS. The 1440p Medium setting provides a good balance, staying above 60 FPS with a minimum of 68 FPS. The Ultra preset at 1440p falls below 60 FPS, indicating the GPU struggles with the highest quality at this resolution.

At 3840x2160, the performance becomes marginal for smooth gameplay: Low averages 70 FPS, Medium averages 47 FPS with a minimum of 40 FPS and maximum of 54 FPS, High averages 40 FPS, and Ultra averages 30 FPS. Only the Low preset at 4K stays above 60 FPS. The Medium preset at 4K has a minimum of 40 FPS, which may cause noticeable stuttering in fast-paced scenes.

The Medium preset is the only one with complete min/max data across all resolutions, providing insight into frame pacing. At 1080p, the range is 99 to 134 FPS, a 35 FPS spread. At 1440p, the range is 68 to 92 FPS, a 24 FPS spread. At 4K, the range is 40 to 54 FPS, a 14 FPS spread. This tightening range at higher resolutions indicates the GPU becomes more consistently loaded, reducing frame time variance.

Settings Recommendations

Based on the measured FPS data, the optimal settings preset depends on the target resolution. For 1080p, the High preset is the best recommendation, delivering 98 FPS average while maintaining visual quality. The Ultra preset at 75 FPS is also viable for those prioritizing graphics, but the 23 FPS difference between High and Ultra may not justify the visual gain. The Medium preset at 116 FPS is the choice for high-refresh-rate monitors, though it sacrifices some visual fidelity.

For 1440p, the Medium preset is the clear winner, averaging 80 FPS with a minimum of 68 FPS that stays above the 60 FPS playability threshold. The High preset at 68 FPS is also acceptable, but its minimum frame rate is not recorded, making Medium the safer choice for consistent performance. The Ultra preset at 51 FPS is not recommended for competitive play, but it remains playable for slower-paced exploration.

For 4K, the Low preset is the only option that maintains an average above 60 FPS, at 70 FPS. The Medium preset at 47 FPS is borderline playable, but the 40 FPS minimum may cause noticeable hitches. The High and Ultra presets at 40 and 30 FPS respectively are best avoided for anything beyond static screenshots. Users with 4K displays should strongly consider lowering resolution to 1440p for a better experience.

The data suggests a general rule: if the target is 60 FPS or higher, use Medium settings at 1440p or Low settings at 4K. For 1080p, High settings provide a good balance, while Medium is recommended for especially demanding scenes. The Ultra preset is only advisable at 1080p, where the 75 FPS average remains acceptable despite the significant performance cost relative to High.

How This Combo Ranks

This specific combination of the AMD Ryzen 7 9700X and AMD Radeon RX 6750 XT ranks 1700th out of 3723 tested combos in Rust, placing it in the 54th percentile of all tested systems. This middle-of-the-pack ranking reflects the GPU's mid-range positioning, as the CPU is a top-tier performer but the graphics card limits overall potential in this GPU-intensive game.

The ranking is particularly telling when considering the CPU's strong synthetic performance. The Ryzen 7 9700X scores in the 86th percentile of all CPUs, yet the combo's in-game rank of 1700 out of 3723 suggests the GPU drags the overall result down. This is consistent with the measured FPS data, which shows the system cannot maintain high frame rates at 4K Ultra, a task that would require a more powerful graphics card.

The RX 6750 XT's 71st percentile GPU ranking further supports this analysis. In a game like Rust, where the GPU is the primary bottleneck at higher resolutions, the graphics card's performance ceiling determines the combo's final ranking. The 12 GB VRAM and 432.0 GB/s bandwidth are sufficient for 1080p and 1440p, but not for pushing the highest settings at 4K.

Users looking at this ranking should understand that it represents a balanced mid-range system. The 1700th position out of 3723 means there are 2023 tested combos that perform worse, and 1699 that perform better. The ranking is not a reflection of the CPU's capability, which is excellent, but rather of the GPU's limitations in a demanding title like Rust. For the majority of players using 1080p or 1440p displays, this combo performs admirably, as evidenced by the 98 FPS at 1080p High and 80 FPS at 1440p Medium. The ranking only becomes a concern for those targeting 4K at high settings, where the data shows the system falls short of the 60 FPS target.
