Rust

The Intel Core i5-12400 paired with the AMD Radeon RX 6600 is a mid-range desktop combination that delivers playable performance in Rust at 1080p and 1440p, but falls short of the 60 FPS threshold at 4K. Benchmark data shows the combo ranks 2975th out of 3723 tested combinations, placing it in the lower portion of the database for this title. This analysis breaks down the measured frame rates, component roles, and settings recommendations based solely on the provided data.

FAQ

Q: What is the best playable setting at 1920x1080 for this combo?

A: The best playable setting at 1080p is High, which produces an average FPS of 69.5, exceeding the 60 FPS playable threshold.

Q: Can this system run Rust at 2560x1440?

A: Yes, but only at Low settings, which delivers an average FPS of 87.5. Medium, High, and Ultra settings all fall below 60 FPS at this resolution.

Q: Is 4K gaming possible with the Intel Core i5-12400 and RX 6600?

A: No. At 3840x2160, even the lowest tested preset (Low) only reaches 51.8 average FPS, which is below the playable threshold of 60 FPS.

Q: How much faster is the RX 6600 at 1080p Low compared to 4K Low?

A: At 1080p Low, the average FPS is 125.4, while at 4K Low it drops to 51.8. This represents a performance increase of approximately 142% at the lower resolution.

Q: What is the performance gap between High and Ultra settings at 1440p?

A: At 2560x1440, High settings deliver 47.7 average FPS, while Ultra drops to 39.4 average FPS. The difference is 8.3 FPS, or about 21% lower performance for Ultra.

Q: Which preset at 1080p provides the highest frame rate?

A: Low settings at 1920x1080 produce the highest average FPS of 125.4, which is more than double the 54.5 FPS seen at Ultra settings.

How This Combo Ranks

The combo rank of 2975 out of 3723 tested combinations places this system in the 20th percentile of all tested hardware pairings for Rust. This means roughly 80% of tested combos deliver better performance in this game. The ranking reflects the mid-range nature of both the i5-12400 and RX 6600, which are positioned well for 1080p gaming but struggle with higher resolutions or demanding presets.

Within the database, this rank indicates the system is better suited for competitive or casual play at 1080p rather than high-fidelity 4K experiences. The measured FPS data supports this: the combo only exceeds 60 FPS at three settings across all resolutions—1080p Low, Medium, and High. The 1440p Low preset also clears the threshold with 87.5 FPS, but every other configuration falls short.

The rank relative to all combos suggests that users seeking consistent 60+ FPS at 1440p or 4K would need more powerful hardware. However, for 1080p gaming, this combination sits in a workable zone, with headroom at Low settings for high-refresh-rate monitors and acceptable performance at High for visual quality.

CPU and GPU Roles

The data reveals a clear pattern of GPU-bound performance as resolution increases. At 1920x1080, the scaling from Low to Ultra shows a range of 125.4 down to 54.5 average FPS, a drop of 56.6% from the lowest to highest preset. This wide spread indicates the GPU is the primary limiter at 1080p, as the CPU can feed frames faster than the RX 6600 can render them at higher quality settings.

Moving to 2560x1440, the same preset scaling produces 87.5 FPS at Low and 39.4 FPS at Ultra, a reduction of 55.0% from Low to Ultra. The absolute values drop compared to 1080p, but the relative scaling remains similar, suggesting the GPU continues to dominate performance at this resolution.

At 3840x2160, the pattern shifts. Low settings yield 51.8 FPS, Medium 32.7 FPS, High 27.3 FPS, and Ultra 22.1 FPS. The gap between Low and Ultra is 57.3%, still indicating GPU limitation, but the overall low frame rates show that the RX 6600's 8 GB GDDR6 memory and 128-bit bus simply cannot sustain playable performance at 4K.

The i5-12400, with its 6 cores and 12 threads, appears sufficient for Rust's CPU demands across all tested resolutions. The consistent percentage drops between presets at each resolution point to the GPU as the bottleneck, rather than the processor. At 1080p Low, the 125.4 FPS result demonstrates the CPU can handle high frame rates when the GPU is not overburdened, confirming that the GPU is the limiting factor in this pairing.

Similar Performance Alternatives

The Intel Core i5-12400's nearest rivals in average benchmark score include the AMD EPYC 7643, which scores 18697 compared to the i5-12400's 18683, a negligible delta of -0.1%. The Intel Core i7-1355U scores 18730, also virtually identical with a -0.3% delta. The AMD Ryzen AI 5 330 offers a score of 18811, which is 0.7% higher, while the Intel Core i3-14100F scores 18519, a 0.9% deficit. These alternatives would behave nearly identically in Rust, with frame rates within 1% of the i5-12400's performance.

For the GPU, the AMD Radeon RX 6600's nearest rivals include the NVIDIA Quadro K6000, which matches the RX 6600's score of 19036 with a 0% delta. The NVIDIA GeForce RTX 4050 Mobile scores 19049, just 0.1% higher, while the NVIDIA Tesla K20m scores 19089, a 0.3% advantage. The NVIDIA RTX 2000 Ada Generation scores 18954, which is 0.4% lower. Any of these GPUs would deliver frame rates nearly indistinguishable from the RX 6600 in Rust, though some may lack equivalent driver support or features.

Users considering hardware swaps can expect similar gaming experiences with these alternatives. The benchmark scores align closely, meaning the measured FPS at each resolution and preset would likely fall within a few frames of the RX 6600's results.

Best Settings per Resolution

At 1920x1080, the most demanding preset that stays at or above 60 FPS is High, which delivers an average of 69.5 FPS. This provides good visual quality while maintaining smooth gameplay. Medium settings offer a buffer with 83.1 FPS, and Low reaches 125.4 FPS for maximum performance.

For 2560x1440, the only preset meeting the 60 FPS threshold is Low, with an average of 87.5 FPS. Medium falls short at 56.8 FPS, so users at this resolution must accept minimal visual settings to maintain playability.

At 3840x2160, no preset achieves 60 FPS. The closest is Low at 51.8 FPS, but this still misses the playable threshold. Users targeting 4K would need to consider lower resolutions or more powerful hardware.

The recommended settings prioritize maintaining at least 60 FPS average, which the data shows is achievable only at 1080p High or lower settings, and 1440p Low.

The Verdict

This PC can run Rust, but only under specific conditions. At 1920x1080, the system delivers playable performance at Low, Medium, and High presets, with High being the best visually demanding option at 69.5 FPS. The 1080p Ultra preset falls below 60 FPS at 54.5 FPS, so it is not recommended for smooth gameplay.

At 2560x1440, only Low settings clear the 60 FPS threshold, achieving 87.5 FPS. Medium, High, and Ultra all fail to reach playable frame rates, with scores of 56.8, 47.7, and 39.4 FPS respectively.

The 3840x2160 resolution is not playable at any preset. Even Low settings only reach 51.8 FPS, and all other presets drop further to 32.7 FPS or below. Users with 4K displays should run the game at 1080p or 1440p to achieve playable frame rates.

Measured FPS Breakdown

1920x1080:

• Low: 125.4 average FPS
• Medium: 83.1 average FPS
• High: 69.5 average FPS
• Ultra: 54.5 average FPS

2560x1440:

• Low: 87.5 average FPS
• Medium: 56.8 average FPS
• High: 47.7 average FPS
• Ultra: 39.4 average FPS

3840x2160:

• Low: 51.8 average FPS
• Medium: 32.7 average FPS
• High: 27.3 average FPS
• Ultra: 22.1 average FPS

The data shows a consistent degradation pattern as resolution and quality increase. At 1080p, frame rates range from 125.4 down to 54.5, covering the full spectrum from high-refresh-rate gaming to borderline playability. The 1440p results halve the top-end performance, with Low still exceeding 60 FPS but all other presets falling below. The 4K results are uniformly poor, with the best case at 51.8 FPS and the worst at 22.1 FPS, confirming the RX 6600's limitations at this resolution. The absence of min and max FPS values in the data limits deeper percentile analysis, but the average scores provide sufficient clarity for settings recommendations.
