Rust

The Intel Core i5-13400F paired with the AMD Radeon RX 7600 XT delivers a performance curve in Rust that clearly illustrates where the graphics card becomes the limiting factor. At 1920x1080 with Low settings, the combo produces an average of 143.1 FPS, which drops to 83.1 FPS at High settings and further to 64.1 FPS at Ultra. Moving to 2560x1440, the Low preset still yields a playable 99.1 FPS, but High falls to 57.1 FPS and Ultra dips to 41 FPS. At 3840x2160, the strain on the GPU is severe: Low manages 59.3 FPS, Medium drops to 41.7 FPS, High plummets to 34.5 FPS, and Ultra bottoms out at 27.8 FPS. The scaling from 1080p Low to 4K Low represents a 58.6% reduction in frame rate, while the same resolution jump at High settings shows a 58.5% drop, indicating that the GPU is the bottleneck across all tested configurations.

The data reveals that the RX 7600 XT is not capable of sustaining high refresh rates at 4K in Rust, regardless of preset. The gap between Low and Ultra at 4K is 31.5 FPS, which is a larger absolute difference than the 19 FPS gap seen at 1080p, confirming that pixel throughput becomes the dominant constraint as resolution increases. The i5-13400F, with its 10 cores and 16 threads, appears sufficient to feed the GPU at lower resolutions where the frame rates are highest, but the measured results suggest that the graphics card's 16 GB of GDDR6 memory on a 128-bit bus with 288.0 GB/s bandwidth cannot overcome the raw compute demands of 3840x2160. The benchmark data positions this combo at rank 1050 out of 1717 tested combinations in Rust, which is slightly below the median, reinforcing that this pairing is better suited for 1080p or 1440p gaming rather than 4K.

Resolution Scaling

The measured FPS data shows a predictable yet steep decline as resolution scales from 1920x1080 to 3840x2160. At Low settings, the average frame rate falls from 143.1 FPS at 1080p to 99.1 FPS at 1440p, then to 59.3 FPS at 4K. This pattern indicates that the RX 7600 XT, with its 2048 shading units and 22.57 TFLOPS of FP32 performance, is being pushed to its limits at higher pixel counts. The drop from 1080p to 1440p at Low settings is 44 FPS, but the drop from 1440p to 4K is 39.8 FPS, showing a slightly shallower curve at the highest resolution, likely because the GPU is already saturated. At Ultra settings, the frame rate declines from 64.1 FPS at 1080p to 41 FPS at 1440p, a 23.1 FPS loss, and then to 27.8 FPS at 4K, an additional 13.2 FPS loss. The percentage reduction from 1080p to 4K at Ultra is 56.6%, nearly identical to the Low preset's 58.6% reduction, suggesting that resolution scaling impacts performance uniformly regardless of graphical complexity.

The data strongly indicates that the RX 7600 XT is the limiting component at 4K, as even the Low preset cannot reach 60 FPS at that resolution. At 1440p, however, the Low preset delivers 99.1 FPS and Medium delivers 67.5 FPS, both above the 60 FPS threshold, while High at 57.1 FPS just misses it. The i5-13400F's performance in synthetic benchmarks, such as a Cinebench R23 multi-core score of 21279 and a single-core score of 3004, suggests that the CPU has ample headroom to drive frame rates at lower resolutions, but the measured FPS at 4K are so low that GPU-bound behavior is evident. The 128-bit memory bus and 288.0 GB/s bandwidth of the RX 7600 XT become a significant hurdle at 4K, where the 16 GB frame buffer must be fed with data at a rate that the bus cannot sustain efficiently.

GPU Role

The AMD Radeon RX 7600 XT plays the critical role in determining Rust's performance, as evidenced by the FPS scaling across resolutions. The GPU's 16 GB of GDDR6 memory is ample for Rust's asset streaming, but the 128-bit bus width and 288.0 GB/s bandwidth limit how quickly textures and geometry can be accessed at high resolutions. The core clocks, with a base of 1980 MHz, a game clock of 2470 MHz, and a boost clock of 2755 MHz, provide the computational throughput, but the measured results show that this is insufficient for 4K Ultra, where the average FPS drops to 27.8. The GPU's 64 ROPs and 176.3 GPixel/s pixel rate are directly stressed by pixel fill at 3840x2160, and the benchmark data shows that even the Low preset at 4K only achieves 59.3 FPS, suggesting that the GPU is operating near its effective ceiling.

The GPU's percentile ranking of 63 among all GPUs, with an average benchmark score of 20146, places it in the mid-range segment. Its nearest rival, the AMD Radeon RX 7600, scores 20258 with a delta of -0.6%, indicating that the XT variant offers negligible performance gains in synthetic tests. In Rust specifically, the combo rank of 1050 out of 1717 suggests that this GPU is not optimized for this title's demanding rendering pipeline. The 22.57 TFLOPS of FP32 compute is the theoretical peak, but real-world performance in Rust is constrained by the memory subsystem and the 128-bit interface. The 32 RT cores are present, but Rust's primary rendering load is rasterization, and the 64 ROPs appear to be the limiting factor at 4K, where the pixel rate of 176.3 GPixel/s is insufficient to maintain high frame rates.

Settings Recommendations

Based solely on the measured FPS data, the optimal settings for this combination depend heavily on the target resolution. At 1920x1080, the Medium preset delivers 96.7 FPS, which is a strong balance between visual quality and performance, while High at 83.1 FPS is also viable for users prioritizing fidelity. Ultra at 64.1 FPS is playable but approaches the lower bound of smooth gameplay. At 2560x1440, the Low preset at 99.1 FPS is the clear recommendation for competitive play, while Medium at 67.5 FPS offers a better visual experience at the cost of 31.6 FPS. High at 57.1 FPS is marginal, and Ultra at 41 FPS is not recommended for fast-paced gameplay. At 3840x2160, the Low preset at 59.3 FPS is the only configuration that approaches playability, but it still falls below the 60 FPS target, and Medium at 41.7 FPS, High at 34.5 FPS, and Ultra at 27.8 FPS are all too slow for a smooth experience.

The data suggests that the sweet spot for this hardware is 1080p with Medium or High settings, where the frame rates are comfortably above 80 FPS. At 1440p, users must compromise with Low settings to achieve high refresh rates. The RX 7600 XT's 16 GB of VRAM is not a limiting factor at any resolution in these measurements, as even the 4K Ultra preset, which would consume significant memory, shows performance degradation due to compute and bandwidth constraints rather than capacity issues. For users with 4K displays, the benchmark results indicate that this GPU cannot provide a satisfactory experience in Rust, and reducing resolution to 1440p or 1080p is necessary for playable frame rates. The measured data does not include any frame generation or upscaling technologies, so the recommendations are based purely on native rendering performance.

Measured FPS Breakdown

At 1920x1080, the average frame rates across presets are as follows: Low delivers 143.1 FPS, Medium delivers 96.7 FPS, High delivers 83.1 FPS, and Ultra delivers 64.1 FPS. The difference between Low and Medium is 46.4 FPS, indicating a significant performance cost for the first step up in quality. The transition from High to Ultra costs 19 FPS, which is a smaller penalty but still substantial. At 2560x1440, the measured averages are 99.1 FPS for Low, 67.5 FPS for Medium, 57.1 FPS for High, and 41 FPS for Ultra. The gap between Low and Medium widens to 31.6 FPS, while the High to Ultra gap is 16.1 FPS. At 3840x2160, the averages are 59.3 FPS for Low, 41.7 FPS for Medium, 34.5 FPS for High, and 27.8 FPS for Ultra. The Low to Medium difference is 17.6 FPS, and the High to Ultra difference is 6.7 FPS, showing that the GPU is so saturated at 4K that preset changes have diminishing returns.

The data shows that the RX 7600 XT can handle 1080p Ultra at 64.1 FPS, which is a viable gaming experience, but 1440p Ultra at 41 FPS is not. The 4K Ultra result of 27.8 FPS is below the threshold for most gaming scenarios. The i5-13400F's Cinebench R23 multi-core score of 21279 and PassMark multi-thread score of 25032 indicate strong CPU performance, but the measured FPS at 4K are so low that the CPU is clearly not the bottleneck in those scenarios. At 1080p Low, the 143.1 FPS result suggests that the CPU is capable of high frame rates, but the GPU's limitations prevent higher performance at 1440p and above. The combo's rank of 1050 out of 1717 in Rust indicates that this pairing is in the lower half of tested configurations, which aligns with the measured FPS being below 60 at 4K and only moderately playable at 1440p.
