GPU Role

The AMD Radeon RX 6750 XT is built on the RDNA 2.0 architecture using the Navi 22 chip on a 7 nm process. It operates with a base clock of 2150 MHz and a game clock of 2495 MHz, boosting up to 2600 MHz. The GPU has 2560 shading units, 160 texture mapping units, and 64 raster operation units. The 12 GB of GDDR6 memory runs at an effective speed of 18 Gbps, delivering a bandwidth of 432.0 GB/s across a 192-bit bus.

In Rust, the GPU's role becomes increasingly dominant as resolution and settings increase. The data shows that at 4K Ultra, the combo drops to 30 FPS average, which is the lowest recorded performance. This is a clear sign that the GPU is saturated at this configuration. The 12 GB VRAM capacity is sufficient for the game's textures, but the raw compute power, rated at 13.31 TFLOPS FP32, is challenged by the highest settings. At 4K High, the average FPS rises to 40, while at 4K Medium it reaches 47 FPS, indicating that the GPU is the primary constraint in this resolution range.

The GPU's percentile ranking against all GPUs is 71, placing it above average. Its nearest rival, the AMD Radeon R9 M395X, has a similar average score (25891 vs 26011), but the RX 6750 XT's modern architecture and faster memory give it an edge in sustained gaming loads. The measured frame times at 1440p Medium (min 68 FPS, max 92 FPS) show that the GPU can handle moderate loads with stable performance, but the jump to 4K reveals its limitations, particularly when settings are pushed to Ultra.

CPU Role

The Intel Core i5-14600KF features 14 cores and 20 threads, with a base clock of 3.50 GHz and a boost clock of 5.30 GHz. It has 24 MB of shared L3 cache and supports dual-channel DDR4 or DDR5 memory. The CPU is unlocked for overclocking and has a TDP of 125 W. It holds a 90th percentile ranking among all CPUs, with an average benchmark score of 49394, placing it just 0.3% above the AMD Ryzen 9 7900.

In Rust, the CPU's impact is most visible at lower resolutions and settings where the GPU is not fully utilized. At 1080p Low, the combo hits 173 FPS average, which is the highest recorded frame rate in the dataset. This suggests that the CPU's 14 cores and high boost clock are sufficient to feed the GPU efficiently at this level. At 1080p High, the average drops to 98 FPS, and at 1080p Ultra it falls to 75 FPS, showing that as the GPU load increases, the CPU becomes less of a bottleneck.

The CPU's multi-core performance, evidenced by a Cinebench R23 multi-core score of 32544, is strong for a game like Rust which is known to utilize multiple threads. However, the single-core score of 4594 in the same test is also critical, as Rust's simulation and physics often rely on single-threaded performance. The measured FPS at 1440p Low (119 FPS average) compared to 1080p Low (173 FPS) indicates a 54 FPS drop, which is more than the GPU's resolution scaling alone would suggest, pointing to a combination of CPU and GPU limits at these settings.

How This Combo Ranks

This combination ranks 1700 out of 3723 tested combos in Rust, placing it in the 45th percentile of all systems. This is a below-average rank, suggesting that many other pairings achieve higher frame rates. The rank reflects the balance between the CPU and GPU, where the CPU is relatively stronger than the GPU in terms of percentile ranking (90th vs 71st). This imbalance means the system may be held back by the GPU in many scenarios, particularly at higher resolutions.

Compared to the nearest rival CPUs, the i5-14600KF is nearly identical in performance to the AMD Ryzen 9 7900 (0.3% faster), but the GPU's rivals are all older or lower-tier models like the AMD Radeon R9 M395X and FirePro W7100. This suggests that the GPU is the weaker link in this pairing. The combo's rank of 1700 indicates that while the CPU is top-tier, the GPU's mid-range standing (71st percentile) drags the overall gaming performance down relative to other tested systems with stronger graphics cards.

The data shows that at 1080p, the system can deliver playable frame rates across all settings, but at 4K, only Low settings (70 FPS) approach a smooth experience. The rank of 1700 likely reflects this limitation at higher resolutions, where many other combos with better GPUs outperform it. The gap between the CPU and GPU performance tiers is evident in the measured FPS, which shows a steady decline as resolution increases, with the GPU becoming the definitive bottleneck.

Resolution Scaling

The measured FPS data shows a clear trend of performance degradation as resolution increases from 1080p to 4K. At Low settings, the average FPS drops from 173 at 1080p to 119 at 1440p (a 31% decrease), and then to 70 at 4K (a further 41% decrease). This scaling pattern is typical of a GPU-bound scenario, where the pixel count directly impacts the rendering load.

At High settings, the drop is similar: from 98 FPS at 1080p to 68 FPS at 1440p (a 31% decrease), and then to 40 FPS at 4K (a 41% decrease). The consistent percentage drops across settings suggest that the GPU's fill rate and memory bandwidth are the primary constraints, rather than the CPU. The GPU's 432.0 GB/s bandwidth and 166.4 GPixel/s pixel rate are being taxed as resolution increases.

However, the scaling is not perfectly linear. At Medium settings, the FPS drops from 116 at 1080p to 80 at 1440p (31% decrease), and then to 47 at 4K (41% decrease). The min FPS at 1080p Medium is 99, while at 1440p Medium it is 68, showing that frame time consistency also suffers at higher resolutions. This indicates that the GPU's compute units (2560 shading units) are struggling to maintain steady frame delivery as the pixel load increases. The 4K Ultra setting, at 30 FPS average, is the most demanding scenario, confirming that the GPU is the limiting component at this resolution.

Measured FPS Breakdown

The dataset includes measured FPS for four settings (Low, Medium, High, Ultra) across three resolutions (1080p, 1440p, 4K). At 1920x1080, the average FPS ranges from 173 at Low to 75 at Ultra. The Medium preset shows a min FPS of 99 and a max FPS of 134, with an average of 116. High settings yield an average of 98 FPS, while Ultra drops to 75 FPS.

At 2560x1440, the performance scales down accordingly. Low settings produce an average of 119 FPS, Medium is 80 FPS (min 68, max 92), High is 68 FPS, and Ultra is 51 FPS. The gap between Low and Ultra at 1440p is 68 FPS, which is larger than the 98 FPS gap at 1080p, indicating that the GPU is being pushed harder.

At 3840x2160, the frame rates become marginal for smooth gameplay. Low settings average 70 FPS, Medium averages 47 FPS (min 40, max 54), High averages 40 FPS, and Ultra averages 30 FPS. The 4K Medium setting is the only one with min/max data, showing a range of 40 to 54 FPS, which indicates some frame time variance. The progression from 1080p Low (173 FPS) to 4K Ultra (30 FPS) represents an 83% reduction in average frame rate, highlighting the GPU's limitations at the highest resolution.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and desired frame rate. For 1080p gaming, the High preset offers a solid 98 FPS average, which is smooth for most players. However, the Low preset at 173 FPS is significantly higher and may be preferable for competitive play where frame rate is prioritized over visual fidelity. The Medium preset at 116 FPS provides a balanced middle ground with a slightly tighter frame time range (99-134 FPS) compared to High.

At 1440p, the Low preset delivers 119 FPS average, making it the only setting that consistently exceeds 100 FPS at this resolution. The Medium preset at 80 FPS is also playable, with a min of 68 FPS ensuring no major stutters. High at 68 FPS is borderline, and Ultra at 51 FPS may feel sluggish for fast-paced gameplay. For a 1440p experience, Low is recommended for the best frame rate, while Medium is acceptable if visual quality is a priority.

At 4K, the GPU struggles to maintain high frame rates. The Low preset at 70 FPS is the only option that approaches smoothness, while Medium at 47 FPS is playable but may have noticeable dips (min 40 FPS). High at 40 FPS and Ultra at 30 FPS are below the threshold for a responsive experience and should be avoided. For 4K, the Low preset is the only viable choice, and players may consider lowering the resolution to 1440p for a better balance of visuals and performance.
