Rust

The Intel Core i5-14600K paired with the AMD Radeon RX 6600 delivers a playable Rust experience at 1080p and 1440p, but it falls short of the 60 FPS threshold at 4K across all tested presets. At 1920x1080, the combination achieves an average of 71.3 FPS on High settings, while the Low preset pushes that figure to 124.2 FPS. The 2560x1440 resolution presents a narrower margin, with only the Low preset clearing 60 FPS at 87.2 FPS on average; Medium settings sit just below the line at 59.7 FPS. At 3840x2160, even the Low preset averages only 51.8 FPS, making 4K generally unplayable for this configuration.

Measured FPS Breakdown

The measured frame rate data for Rust on this hardware configuration reveals a clear scaling pattern across resolutions and quality presets. At 1920x1080, the Low preset delivers the highest average at 124.2 FPS, followed by Medium at 82.4 FPS and High at 71.3 FPS. The Ultra preset drops to 55.7 FPS, which falls below the 60 FPS playability threshold. This represents a substantial gap between Low and Ultra—the difference between the two extremes is 68.5 FPS, indicating that the RX 6600’s 8 GB memory buffer and RDNA 2.0 architecture are heavily taxed by the highest quality settings.

Moving to 2560x1440, the performance curve compresses significantly. Low settings produce an average of 87.2 FPS, while Medium drops to 59.7 FPS—just under the playable mark. High averages 47.3 FPS, and Ultra falls to 35.4 FPS. The delta between Low and Ultra at this resolution is 51.8 FPS, a slightly smaller spread than at 1080p, suggesting that resolution scaling affects both low and high presets similarly. Notably, the jump from Low to Medium at 1440p costs 27.5 FPS, which is a steeper penalty than the 41.8 FPS drop seen from Low to Medium at 1080p.

At 3840x2160, the RX 6600 struggles across the board. Low settings average 51.8 FPS, Medium drops to 33.6 FPS, High manages 29 FPS, and Ultra bottoms out at 22.5 FPS. No preset at 4K reaches the 60 FPS threshold, and even the most optimized Low preset falls short by 8.2 FPS. The scaling from Low to Ultra at 4K shows a 29.3 FPS reduction, which is the smallest absolute drop across all resolutions—but this is because the baseline is already so low that the GPU is likely bottlenecked at every quality level.

How This Combo Ranks

The combo rank for this specific CPU-GPU pairing in Rust places it at position 2966 out of 3723 tested combinations. This percentile positioning—roughly the 20th percentile—indicates that the i5-14600K and RX 6600 are outperformed by a substantial majority of other hardware configurations tested in this game. The CPU itself sits in the 90th percentile among all processors, with an average benchmark score of 48618, meaning the processor is far more capable than the GPU in this pairing. The GPU, by contrast, ranks in the 63rd percentile among all graphics cards, with an average benchmark score of 19036.

The discrepancy between the CPU’s high percentile ranking and the combo’s low game-specific rank points to the RX 6600 as the limiting factor. The i5-14600K’s 14 cores and 20 threads, along with its 24 MB of shared L3 cache, provide ample headroom for Rust’s simulation and physics workloads. However, the GPU’s 8 GB of GDDR6 memory and 128-bit bus width—yielding 224.0 GB/s of bandwidth—constrain frame rates at higher resolutions and settings. In a game like Rust, where draw distances and entity counts scale heavily with resolution, the GPU’s memory bandwidth becomes the bottleneck well before the CPU’s processing capabilities are exhausted.

Similar Performance Alternatives

The nearest rivals for the Intel Core i5-14600K include the Intel Xeon Gold 5318H (average score 48698, delta -0.2%), AMD EPYC 4345P (48470, delta +0.3%), Intel Core Ultra 5 245HX (48287, delta +0.7%), and Intel Core Ultra 5 245 (48995, delta -0.8%). These processors all fall within 0.8% of the i5-14600K’s average benchmark score, meaning any of them would deliver nearly identical CPU-bound performance in Rust. The Xeon Gold 5318H and Core Ultra 5 245 are marginally ahead, while the EPYC 4345P and Core Ultra 5 245HX are slightly behind, but these differences would be imperceptible in actual gameplay.

On the GPU side, the Radeon RX 6600’s nearest rivals are the NVIDIA Quadro K6000 (19030, delta 0%), NVIDIA GeForce RTX 4050 Mobile (19049, delta -0.1%), NVIDIA Tesla K20m (19089, delta -0.3%), and NVIDIA RTX 2000 Ada Generation (18954, delta +0.4%). The Quadro K6000 and RTX 4050 Mobile are essentially tied with the RX 6600 in average benchmark scores, while the Tesla K20m is 0.3% behind and the RTX 2000 Ada Generation is 0.4% ahead. For gaming purposes, swapping the RX 6600 for any of these would produce frame rates within a few percent of the measured results—none would push the combo meaningfully higher in the Rust ranking.

The Verdict

This PC can run Rust at 1920x1080 with High settings, maintaining an average of 71.3 FPS, which clears the 60 FPS playability threshold by 18.8%. At 2560x1440, only the Low preset achieves playable performance, averaging 87.2 FPS—a comfortable margin of 45.3% over the threshold. The 3840x2160 resolution is not viable for this configuration, as the best-case Low preset averages only 51.8 FPS, which is 13.7% below the playable mark.

For 1080p gaming, the High preset is the recommended ceiling; Ultra drops to 55.7 FPS, which would introduce noticeable stutter in fast-paced combat scenarios. At 1440p, players must accept Low settings to maintain smooth gameplay, as Medium falls just short at 59.7 FPS—a tantalizingly close miss that could be playable for some, but not reliably above the threshold. The data indicates that this pairing is best suited for 1080p High or 1440p Low, with no headroom for 4K gaming without significant compromises in visual quality or frame rate.

Best Settings per Resolution

At 1920x1080, the most demanding preset that stays at or above 60 FPS is High, with an average of 71.3 FPS. This provides a 18.8% margin above the playable threshold, making it the recommended choice for 1080p gaming. The Medium preset averages 82.4 FPS and Low averages 124.2 FPS, but High offers the best visual quality while maintaining comfortable headroom.

At 2560x1440, the only playable preset is Low, averaging 87.2 FPS. This is 45.3% above the 60 FPS threshold, providing smooth gameplay but requiring significant visual compromises. Medium settings at 1440p average 59.7 FPS, which is below the threshold and not recommended for consistent performance.

At 3840x2160, no preset achieves 60 FPS. The best option is Low at 51.8 FPS, but this falls short of the playable threshold. For users wanting 4K, this hardware combination would need a more powerful GPU to reach playable frame rates.
