Rust

The Intel Core i5-12400 paired with the AMD Radeon RX 7700 XT delivers a solid Rust experience, but the playable envelope varies sharply by resolution. At 1080p, the combo clears 60 FPS on every preset, including Ultra at 81.7 FPS. At 1440p, High settings remain comfortably above the threshold at 75.6 FPS, while Ultra dips to 55.3 FPS. At 4K, only Low settings stay playable at 77.6 FPS, with Medium at 51.9 FPS and High at 45 FPS falling short. The data indicates this is a capable 1080p and 1440p machine for Rust, with 4K requiring significant graphical compromises.

Measured FPS Breakdown

The measured FPS data for this CPU-GPU pairing spans three resolutions and four quality presets. At 1920x1080, the results are consistently strong. Low settings produce an average of 190.2 FPS, which is the highest frame rate recorded across the entire dataset. Medium settings follow at 128.5 FPS, High at 109.1 FPS, and even the most demanding Ultra preset maintains 81.7 FPS. Every 1080p configuration clears the 60 FPS playable threshold, with Ultra still holding a 21.7 FPS margin above that line.

Moving to 2560x1440, the performance profile shifts downward but remains mostly playable. Low settings deliver 130 FPS, a figure that still exceeds the 1080p High result. Medium settings produce 85.7 FPS, and High settings reach 75.6 FPS. However, Ultra drops to 55.3 FPS, which falls 4.7 FPS below the 60 FPS threshold. The gap between Low and Ultra at 1440p is 74.7 FPS, indicating a steep cost for the highest visual quality.

At 3840x2160, the picture changes dramatically. Low settings average 77.6 FPS, which is the only 4K preset that remains playable. Medium settings drop to 51.9 FPS, High to 45 FPS, and Ultra to 33.4 FPS. The spread from Low to Ultra at 4K is 44.2 FPS, with each preset tier costing roughly 10-15 FPS. The 4K Ultra result is less than half the 1080p Low result, highlighting the resolution’s heavy toll on the GPU.

Comparing across resolutions at the same preset, the scaling is steep. At High settings, 1080p yields 109.1 FPS, 1440p yields 75.6 FPS, and 4K yields 45 FPS. That represents a 30.8% drop from 1080p to 1440p and a further 40.5% drop from 1440p to 4K. At Low settings, the progression is 190.2 FPS → 130 FPS → 77.6 FPS, showing that even the lowest quality preset cannot fully offset the pixel-count increase at 4K.

CPU and GPU Roles

The benchmark data reveals that the RX 7700 XT is the primary performance driver in this pairing, with the i5-12400 providing sufficient headroom at lower resolutions. The most telling evidence is the FPS scaling between presets at each resolution. At 1080p, Low settings produce 190.2 FPS, while Ultra produces 81.7 FPS — a 108.5 FPS difference that is almost entirely attributable to GPU workload. The CPU’s role is to feed the GPU quickly enough; the i5-12400’s 3DMark single-thread score of 910 and passmark_single_thread score of 3456 suggest it can handle Rust’s simulation and draw-call overhead without bottlenecking at these frame rates.

At 1440p, the GPU load increases, and the FPS differences between presets compress slightly. Low hits 130 FPS, Medium 85.7, High 75.6, and Ultra 55.3. The delta between Low and Ultra is 74.7 FPS, narrower than the 108.5 FPS gap at 1080p. This indicates the GPU is becoming the limiting factor as resolution rises, with the CPU having more idle time between frames. The i5-12400’s Cinebench R23 multicore score of 15989 and 12 threads provide ample parallel processing for Rust’s server-side and client-side logic, but at 4K the GPU saturates well before the CPU is stressed.

At 3840x2160, the GPU’s dominance is absolute. Low settings yield 77.6 FPS, while Ultra yields 33.4 FPS — a 44.2 FPS gap that is purely GPU-bound. The CPU’s performance is nearly irrelevant at this resolution; the RX 7700 XT’s 12 GB of GDDR6 memory and 432.0 GB/s bandwidth are the constraining factors. The 4K Ultra result of 33.4 FPS is close to the GPU’s 3DMark Steel Nomad DX12 score of 3316, suggesting that Rust’s Ultra preset at 4K is pushing the card to its architectural limits.

The resolution scaling also clarifies roles. At 1080p, the CPU has more influence because frame rates are high and per-frame CPU time matters more. The i5-12400’s boost clock of 4.40 GHz and 18 MB of shared L3 cache help maintain consistent frame delivery. At 1440p and 4K, the GPU takes over entirely, as evidenced by the sharper FPS declines when moving from 1080p to 1440p (e.g., High drops from 109.1 to 75.6) versus the smaller absolute differences between presets at each higher resolution.

Similar Performance Alternatives

The nearestRivals data for the CPU and GPU provides context for what other hardware would behave similarly in Rust. For the Intel Core i5-12400, the closest rival is the AMD EPYC 7643, which scores 18697 in average benchmark versus the i5-12400’s 18683, a delta of -0.1%. This server-class chip would deliver nearly identical CPU-side performance in Rust, though its platform characteristics differ. The Intel Core i7-1355U is 0.3% slower, and the AMD Ryzen AI 5 330 is 0.7% slower — all three are effectively indistinguishable from the i5-12400 in CPU-bound scenarios. On the faster side, the Intel Core i3-14100F is 0.9% ahead, meaning it would provide a marginal uplift in frame pacing at 1080p Low where CPU load is highest.

For the AMD Radeon RX 7700 XT, the rival landscape is similarly tight. The NVIDIA GeForce RTX 5060 Mobile scores 22435 versus the RX 7700 XT’s 22547, a delta of 0.5% (meaning the RX 7700 XT is 0.5% faster). The NVIDIA GeForce RTX 4060 Mobile is 0.8% slower, and the NVIDIA GeForce RTX 2080 is 1.5% slower. The AMD Radeon RX 5700 is 1.7% faster, making it the closest performance peer among the listed rivals. In Rust specifically, these small deltas translate to FPS differences of less than 2 FPS at most settings — for instance, the RX 5700 would produce roughly 78 FPS at 4K Low versus the RX 7700 XT’s 77.6 FPS.

It is important to note that two of the GPU rivals are mobile parts (RTX 5060 Mobile and RTX 4060 Mobile), which in practice are constrained by laptop thermal and power limits. However, the benchmark scores suggest their desktop-class performance would be comparable. The RTX 2080, an older desktop card, would track within 1.5% of the RX 7700 XT across Rust’s presets, meaning it would also fall below 60 FPS at 1440p Ultra and 4K Medium.

The Verdict

This PC can run Rust successfully, but the playable resolution ceiling is clearly defined by the data. At 1920x1080, all four presets — Low, Medium, High, and Ultra — clear the 60 FPS threshold. The Ultra preset at 81.7 FPS is the best visual setting that remains playable, offering a 21.7 FPS buffer above the playable threshold. At 2560x1440, three presets are playable: High at 75.6 FPS, Medium at 85.7 FPS, and Low at 130 FPS. The Ultra preset at 55.3 FPS is not playable, falling 4.7 FPS short. At 3840x2160, only Low settings at 77.6 FPS meet the 60 FPS requirement; Medium at 51.9 FPS, High at 45 FPS, and Ultra at 33.4 FPS all fail.

The verdict by resolution is unambiguous. For 1080p, the system is fully capable of maxing out Rust’s settings. For 1440p, players must choose High or lower to maintain smooth gameplay. For 4K, only the Low preset is viable, and even that carries a modest frame rate of 77.6 FPS, which is playable but not high-refresh territory. The data shows no scenario where this combo achieves 60 FPS at 4K with Medium or higher settings.

The combo’s overall rank in the game database is 1374 out of 3723 tested combinations, placing it in the top 36.9% of systems. This is a respectable standing, but it also indicates that many other pairings can outperform it, particularly at higher resolutions. The i5-12400’s percentile of 72 among all CPUs and the RX 7700 XT’s percentile of 67 among GPUs reinforce the mid-range positioning of this build.

A: Yes. The 4K Low preset averages 77.6 FPS, while 1440p Ultra averages 55.3 FPS. The lower resolution with higher settings is less playable than the higher resolution with lower settings, indicating that preset quality has a larger impact than resolution in this range.

Best Settings per Resolution

At 1920x1080, the most demanding preset that stays at or above 60 FPS is Ultra, with a measured average of 81.7 FPS. This is the recommended configuration for 1080p, as it delivers the highest visual fidelity while maintaining a comfortable margin above the playable threshold. Lower presets are also available — Medium at 128.5 FPS, High at 109.1 FPS, and Low at 190.2 FPS — but they sacrifice quality without a meaningful frame rate benefit at this resolution.

At 2560x1440, the best playable setting is High, averaging 75.6 FPS. This provides a 15.6 FPS buffer over the 60 FPS threshold. Medium at 85.7 FPS and Low at 130 FPS are also playable, but High offers the best balance of visual quality and performance. Ultra at 55.3 FPS is not recommended, as it falls below the threshold.

At 3840x2160, the only playable preset is Low, with an average of 77.6 FPS. This is the best setting for 4K, as Medium (51.9 FPS), High (45 FPS), and Ultra (33.4 FPS) all fail to reach 60 FPS. The 4K Low result is still 17.6 FPS above the threshold, so there is some headroom, but no quality preset above Low should be selected for smooth gameplay.
