Rust

The Intel Core i5-12400F paired with the AMD Radeon RX 6600 delivers a highly playable Rust experience at 1080p, with clear headroom for high settings, while 1440p and 4K demand significant preset compromises due to the GPU's limitations. The benchmark data, measured across three resolutions and four quality presets, reveals a system that scales predictably with graphical load, but which hits a hard wall at Ultra settings beyond 1080p.

Measured FPS Breakdown

At 1920x1080, the combination of the i5-12400F and RX 6600 produces a robust performance envelope. The Low preset yields an average of 124.5 FPS, which is more than double the 60 FPS playable threshold. Moving to Medium, the average drops to 85.6 FPS, still comfortably above the threshold. The High preset maintains an average of 69.2 FPS, which is the highest quality setting that clears the 60 FPS bar at this resolution. The Ultra preset, however, falls to an average of 52 FPS, dipping below the playable mark—a significant 17.2 FPS drop from High, indicating that the transition from High to Ultra is the steepest performance cliff at 1080p.

Stepping up to 2560x1440, the performance picture changes dramatically. The Low preset delivers an average of 86.8 FPS, which is the only playable setting at this resolution. Medium falls to 58.6 FPS, just 1.4 FPS short of the 60 FPS threshold, making it a marginal miss. High drops further to 52.1 FPS, and Ultra plunges to 38.3 FPS. The scaling from Low to Medium at 1440p represents a 28.2 FPS loss, which is proportionally larger than the 38.9 FPS loss seen from Low to Medium at 1080p, suggesting the GPU becomes a more dominant bottleneck as resolution increases.

At 3840x2160, the system struggles to maintain playable framerates across all presets. The Low preset averages 50.6 FPS, which is below the 60 FPS threshold. Medium drops to 32 FPS, High falls to 27.9 FPS, and Ultra bottoms out at 24.7 FPS. The gap between Low and Ultra at 4K is 25.9 FPS, but the relative performance loss is severe: Ultra runs at less than half the speed of Low. No preset at 4K achieves the playable threshold, confirming that this resolution is out of reach for this hardware combination.

CPU and GPU Roles

The data reveals a clear division of labor between the i5-12400F and RX 6600, with the GPU acting as the primary performance limiter at higher resolutions. The CPU, with its 6 cores and 12 threads, provides sufficient headroom to avoid becoming the bottleneck at 1080p, where the GPU is able to push framerates well beyond 100 FPS on Low settings. The fact that the system reaches 124.5 FPS at 1080p Low suggests the CPU can feed the GPU adequately even at high framerates, though the precise CPU limit is not directly measurable from the provided data.

As resolution increases, the GPU's workload grows exponentially, and the RX 6600's 8 GB of GDDR6 memory and 224.0 GB/s bandwidth begin to constrain performance. The scaling from 1080p to 1440p at the same preset shows this clearly: Low drops from 124.5 to 86.8 FPS (a 30.3% reduction), Medium from 85.6 to 58.6 FPS (a 31.5% reduction), and High from 69.2 to 52.1 FPS (a 24.7% reduction). These are consistent, large drops that point to the GPU being fully utilized at both resolutions.

The 1440p to 4K transition further confirms GPU dominance. At Low, the framerate drops from 86.8 to 50.6 FPS (a 41.7% reduction), while at High it falls from 52.1 to 27.9 FPS (a 46.5% reduction). The increasingly severe percentage drops as resolution rises indicate that the RX 6600's shading units (1,792) and texture mapping units (112) are being pushed to their limits. The CPU's role becomes secondary; even at 4K Low, where the GPU is stressed, the i5-12400F's single-thread performance (3dmark_single_thread score of 909) is sufficient to avoid stalling the pipeline.

Preset scaling within a resolution also hints at the CPU's capability. At 1080p, the jump from Low to Medium costs 38.9 FPS, while from Medium to High costs 16.4 FPS. The larger drop from Low to Medium suggests that the GPU is initially underutilized at Low settings, allowing the CPU to drive higher framerates, but once Medium is applied, the GPU begins to saturate. This pattern holds at 1440p, where Low to Medium costs 28.2 FPS, but Medium to High only costs 6.5 FPS—indicating the GPU is already near its limit at Medium, so additional graphical fidelity has diminishing returns.

FAQ

A: Yes. The measured average FPS at 1920x1080 with High settings is 69.2 FPS, which exceeds the 60 FPS playable threshold.

Q: What is the best playable preset at 1440p?

A: The Low preset is the only playable option at 2560x1440, delivering an average of 86.8 FPS. Medium preset falls just short at 58.6 FPS.

Q: Is 4K gaming possible with this hardware?

A: No. All four presets at 3840x2160—Low (50.6 FPS), Medium (32 FPS), High (27.9 FPS), and Ultra (24.7 FPS)—fall below the 60 FPS playable threshold.

Q: How much performance is lost when moving from 1080p to 1440p at High settings?

A: The High preset, with an average of 69.2 FPS. The Ultra preset drops to 52 FPS, which is below the 60 FPS threshold.

The Verdict

This PC can run Rust, but the playable experience is heavily dependent on resolution and preset selection. At 1920x1080, the system delivers playable performance on Low, Medium, and High presets, with High being the best quality option at 69.2 FPS average. The Ultra preset at 1080p is not playable, falling to 52 FPS. At 2560x1440, only the Low preset clears the 60 FPS bar, achieving 86.8 FPS average; Medium falls just short at 58.6 FPS, and High and Ultra are not viable. At 3840x2160, no preset reaches the playable threshold, with the best option being Low at 50.6 FPS. The verdict is clear: this is a 1080p gaming machine with limited 1440p capability and no 4K viability for Rust.

Similar Performance Alternatives

The CPU's nearest rivals, based on average benchmark scores, offer nearly identical performance. The AMD Ryzen 5 7535HS scores 19,047, which is effectively the same as the i5-12400F's 19,039 (a delta of 0%). The Intel Core 3 201E scores 19,056, just 0.1% higher, while the Intel Core i5-1335U scores 18,982, a 0.3% difference. The AMD EPYC 7773X matches at 18,979, also 0.3% lower. These CPUs would behave nearly identically in Rust, meaning the i5-12400F's 6-core, 12-thread configuration is well-matched against these alternatives, none of which would meaningfully shift the framerate results.

On the GPU side, the RX 6600's nearest rivals show a similar pattern. The NVIDIA Quadro K6000 matches with an average score of 19,030 (0% delta). The NVIDIA GeForce RTX 4050 Mobile is just 0.1% higher at 19,049, and the NVIDIA Tesla K20m scores 19,089, a 0.3% difference. The NVIDIA RTX 2000 Ada Generation is 0.4% lower at 18,954. All of these GPUs would produce nearly identical FPS numbers in Rust, so users with any of these alternatives would see the same resolution and preset limitations. Notably, the RX 6600's 8 GB VRAM is a shared trait with some of these rivals, reinforcing the GPU-bound behavior observed at higher resolutions.

Best Settings per Resolution

At 1920x1080, the most demanding preset that maintains at least 60 FPS is High, with an average of 69.2 FPS. This provides a comfortable margin above the threshold while allowing for superior visual quality. At 2560x1440, the only playable preset is Low, which delivers an average of 86.8 FPS—this is the recommended setting, though it leaves significant graphical fidelity on the table. At 3840x2160, no preset achieves 60 FPS, so there is no recommended playable setting; the best average is 50.6 FPS on Low, but this still falls short of the playable threshold.

How This Combo Ranks

Among 3,723 tested combinations in Rust, this specific pairing of the Intel Core i5-12400F and AMD Radeon RX 6600 ranks at position 2,930. This places the combo in the lower percentile of tested systems, which is consistent with the measured FPS data showing that 4K is unplayable and 1440p is limited to Low settings. The rank reflects the GPU's modest performance ceiling—the RX 6600 sits at the 63rd percentile among all GPUs, while the CPU is at the 73rd percentile among all CPUs. The combination's rank suggests that while the CPU is capable, the GPU holds back overall performance, particularly at higher resolutions. Users seeking better 4K or high-refresh 1440p performance would need to look at combinations further up the ranking list, as this setup is firmly positioned for 1080p gaming.
