Rust

The Intel Core i5-12400 paired with the AMD Radeon RX 5700 XT delivers a solid 1080p experience in Rust, but the data shows a steep performance cliff as resolution increases, indicating a GPU-bound system at higher settings. The combo ranks in the 28th percentile (1235 out of 1717 tested combos), yet it still achieves playable frame rates at 1440p with optimized settings, making it a balanced pairing for 1080p high-refresh monitors.

FAQ

Q: What is the best resolution and settings combo for this system in Rust?

A: The measured data shows the optimal experience is at 1920x1080 with Low settings, producing an average of 138.5 FPS. For higher visual fidelity, Medium settings at 1080p still deliver a smooth 89.5 FPS average, while High settings yield 77.7 FPS.

Q: Can this combo handle 1440p gaming in Rust?

A: Yes, but with caveats. At 2560x1440, Low settings achieve a 95.2 FPS average, which is excellent. Medium drops to 62.4 FPS, High to 55.1 FPS, and Ultra falls to 42 FPS. For competitive play, Low or Medium is viable; for immersive visuals, High is borderline acceptable.

Q: How does the CPU compare to its direct rivals?

A: The Intel Core i5-12400 has an average benchmark score of 19850, placing it in the 77th percentile of all CPUs. It is nearly identical to the Intel Core i7-9700 (19831, 0.1% faster) and the Intel Core i7-8700 (19894, 0.2% slower), showing it trades blows with older i7 parts.

Q: Is the GPU a bottleneck at 4K resolution?

A: Yes, the data strongly indicates this. At 3840x2160, even Low settings only produce 56.5 FPS, and Ultra falls to a stutter-prone 25 FPS. The RX 5700 XT’s 8 GB of VRAM and 448.0 GB/s bandwidth are insufficient for smooth 4K gameplay in Rust.

Q: What is the CPU’s architecture and core configuration?

A: The i5-12400 is an Alder Lake-S part with 6 cores and 12 threads. It has a base clock of 2.50 GHz and a boost clock of 4.40 GHz, with 18 MB of shared L3 cache. It supports both DDR4 and DDR5 memory.

Q: How does the GPU’s benchmark score position it against rivals?

A: The RX 5700 XT scores 24731 in average benchmarks, placing it in the 68th percentile of all GPUs. It is statistically tied with the NVIDIA RTX A5000 Mobile (24763, 0.1% faster) and the Intel Arc A350M (24647, 0.3% slower).

CPU Role

The Intel Core i5-12400 is a 6-core, 12-thread processor from the Alder Lake family, built on Intel’s 10 nm process. It operates with a 2.50 GHz base clock and a 4.40 GHz boost clock, paired with 18 MB of shared L3 cache. In Rust, a game known for its heavy server-side and simulation logic, this CPU provides a strong foundation, as evidenced by its 77th percentile ranking among all CPUs.

Benchmark results show the i5-12400 holds its own against older high-end parts. Its Cinebench R23 multicore score of 15935 and single-core score of 2249 highlight a balanced throughput. In the measured FPS data, the CPU’s influence is most visible at lower resolutions and settings, where the GPU is not the primary limiter. At 1080p Low, the system reaches 138.5 FPS, a figure that relies on the processor’s ability to feed the GPU with game state updates quickly. The 3DMark scores reinforce this: 5873 in the 16-thread test and 1692 in the 2-thread test, showing strong scaling.

Compared to its nearest rivals, the i5-12400 is effectively a peer of the Intel Core i7-9700 (0.1% faster) and the Intel Core i7-8700 (0.2% slower). This means the CPU is not a weak link in this combination; it offers enough single-thread performance for Rust’s core loop and enough multi-thread muscle for background tasks.

Settings Recommendations

For this hardware, the data clearly favors 1080p as the primary resolution. At 1920x1080, Low settings produce an average of 138.5 FPS, which is ideal for competitive play or high-refresh monitors. If visual quality is a priority, Medium settings at 89.5 FPS provide a good balance, while High at 77.7 FPS remains fluid enough for most players. Ultra at 61.4 FPS is playable but begins to dip below the 60 FPS threshold, making it less desirable for fast-paced action.

At 1440p, the picture changes. Low settings yield 95.2 FPS, which is still excellent, but Medium drops to 62.4 FPS and High to 55.1 FPS. The sweet spot for 1440p is Low, as it maintains a comfortable margin above 60 FPS. Ultra at 1440p (42 FPS) is only suitable for slower, exploratory play. For 4K, the data shows all settings struggle; Low hits 56.5 FPS, but Medium and High fall to 34.9 and 33.7 FPS, respectively, with Ultra at 25 FPS. The recommendation is to stick to 1080p Medium or 1440p Low for an optimal balance of visuals and smoothness.

How This Combo Ranks

This specific combination of the Intel Core i5-12400 and AMD Radeon RX 5700 XT ranks 1235 out of 1717 tested combos in Rust, placing it in the bottom 28% of all pairings. This rank is surprising given the hardware’s individual performance, but it reflects the game’s demanding nature at higher resolutions. The CPU’s 77th percentile and GPU’s 68th percentile scores suggest a balanced pairing, yet the overall combo rank indicates that many other systems outperform it in Rust’s specific workload.

The rank suggests that while this setup is capable, it is not a top-tier combination for Rust. The data shows that the GPU becomes a significant bottleneck at 1440p and above, which likely drags the overall rank down. In contrast, the CPU’s strong showing in synthetic benchmarks does not translate to top-tier framerates in this title, highlighting Rust’s sensitivity to both components.

GPU Role

The AMD Radeon RX 5700 XT is built on the RDNA 1.0 architecture with the Navi 10 chip, fabricated on TSMC’s 7 nm process. It features 8 GB of GDDR6 memory on a 256-bit bus, delivering 448.0 GB/s of bandwidth. The GPU has a base clock of 1605 MHz, a game clock of 1755 MHz, and a boost clock of 1905 MHz. Its compute power is rated at 9.754 TFLOPS FP32, with a pixel rate of 121.9 GPixel/s and a texture rate of 304.8 GTexel/s.

In Rust, the GPU’s role is dominant at higher settings and resolutions. The measured FPS data shows a clear pattern: at 1080p, the GPU can handle the load, but as resolution increases, framerates drop disproportionately. At 4K Ultra, the average FPS is 25, which is unplayable, while at 1080p Low, it reaches 138.5 FPS. This indicates that the RX 5700 XT’s 8 GB VRAM and bandwidth are sufficient for 1080p but become the limiting factor at higher resolutions.

The GPU’s benchmark percentile of 68% and its average score of 24731 place it in the mid-range category. Its nearest rivals include the NVIDIA RTX A5000 Mobile (0.1% faster) and the Intel Arc A350M (0.3% slower), showing it sits in a competitive but crowded field. For Rust specifically, the GPU’s performance is adequate for 1080p gaming but falls short of delivering a premium experience at 1440p or 4K.

Measured FPS Breakdown

The measured FPS data provides a clear picture of this combo’s capabilities. At 1920x1080, the results are as follows: Low settings average 138.5 FPS, Medium 89.5 FPS, High 77.7 FPS, and Ultra 61.4 FPS. This shows a steady decline as settings increase, with a 55.6% drop from Low to Ultra.

Moving to 2560x1440, the averages are: Low 95.2 FPS, Medium 62.4 FPS, High 55.1 FPS, and Ultra 42 FPS. The drop from Low to Ultra is 55.9%, similar to 1080p, but the absolute numbers are lower, indicating the GPU is working harder. At 3840x2160, the results are: Low 56.5 FPS, Medium 34.9 FPS, High 33.7 FPS, and Ultra 25 FPS. The drop from Low to Ultra is 55.8%, but the low starting point makes even Low settings marginal for smooth gameplay.

These numbers reveal that the system is consistently capable of around 60 FPS at 1080p High and 1440p Low, but struggles to maintain that threshold at higher settings or resolutions.

Resolution Scaling

The scaling from 1080p to 4K is steep and consistent across all settings. At Low settings, the average FPS drops from 138.5 at 1080p to 95.2 at 1440p (a 31.3% decrease) and then to 56.5 at 4K (a 40.7% decrease from 1440p). At High settings, the drop is from 77.7 at 1080p to 55.1 at 1440p (29.1%) and then to 33.7 at 4K (38.8%). This pattern shows that the GPU is the limiting component, as the framerate scales almost inversely with pixel count.

The data suggests that the CPU is not the primary bottleneck at higher resolutions. If the CPU were the limit, the framerate would remain relatively flat across resolutions. Instead, the significant drops indicate that the RX 5700 XT’s memory bandwidth and compute power are being saturated. At 4K, the system falls below 60 FPS even at Low settings, confirming that this resolution is out of reach for this combo. The most efficient use of this hardware is at 1080p, where the GPU can deliver high framerates with room to spare.
