Rust

The Intel Core i5-12400 paired with the AMD Radeon RX 6650 XT ranks 2363rd out of 3723 tested combinations for Rust, placing it in the lower-middle portion of the database. This position reflects a system that is capable of running the game comfortably at standard resolutions, but one that will require careful settings management at higher pixel counts. The data shows a clear pattern: the combo delivers playable performance at 1080p and 1440p with the right presets, while 4K remains viable only at the lowest quality level. The following analysis breaks down exactly where this pairing stands, what alternatives exist, and which settings yield the best experience.

How This Combo Ranks

The combination of the Core i5-12400 and Radeon RX 6650 XT sits at rank 2363 out of 3723 tested combos in Rust, which means roughly 63% of tested systems perform better in this specific title. This percentile positioning is not surprising given the hardware profile: the CPU holds a 72nd percentile ranking among all processors, while the GPU sits at the 65th percentile among all graphics cards. Neither component is a top-tier performer, but both are solidly mid-range, and the game’s demands at higher resolutions push the pairing down the overall list.

Benchmark results indicate the CPU is the stronger half of this duo. The i5-12400 achieves a Cinebench R23 multi-core score of 15989 and a single-core score of 2257, with a Passmark multithread score of 18747. These numbers place it ahead of several rivals in the database, including the AMD EPYC 7643 by 0.1%, the Intel Core i7-1355U by 0.3%, and the AMD Ryzen AI 5 330 by 0.7%. The only nearby competitor that edges it out is the Intel Core i3-14100F, which scores 0.9% higher. For a game like Rust, which is known to be CPU-sensitive in busy scenes, this level of single-threaded performance matters.

The GPU, meanwhile, posts a Passmark G3D score of 17166 and an average benchmark score of 19765. Its nearest rivals in the database are all professional or workstation-class cards: the NVIDIA Tesla K40m is 0.6% faster, the AMD FirePro D300 is 0.7% slower, the AMD FirePro W7000 is 0.7% slower, and the NVIDIA Quadro K5200 is 0.8% slower. This clustering suggests the RX 6650 XT delivers roughly equivalent raw graphics throughput to those older pro cards, but with modern architecture advantages like RDNA 2.0 and DirectX 12 Ultimate support.

The overall rank of 2363 reflects how these two components interact in Rust specifically. At 1080p Ultra, the combo hits 60.2 FPS average, which is exactly at the playable threshold. At 1440p Medium, it manages 65.1 FPS, and at 4K Low, it reaches 60.2 FPS. These numbers show that the system is right at the edge of playability at multiple resolution/preset combinations, which explains why it does not rank higher overall.

Similar Performance Alternatives

Looking at the nearest rivals for the CPU, the data shows that the i5-12400 performs nearly identically to several other processors in synthetic benchmarks. The AMD EPYC 7643 scores 18697 on average, which is 0.1% lower than the i5-12400’s 18683. The Intel Core i7-1355U scores 18730, or 0.3% higher. The AMD Ryzen AI 5 330 scores 18811, which is 0.7% higher. The Intel Core i3-14100F scores 18519, which is 0.9% lower. In practical terms, any of these CPUs would behave similarly in Rust, though the i5-12400’s 6 cores and 12 threads give it a slight edge in multi-threaded scenes compared to the i3-14100F.

For the GPU, the nearest rivals are older workstation cards, which is an interesting comparison. The NVIDIA Tesla K40m averages 19885, or 0.6% higher than the RX 6650 XT’s 19765. The AMD FirePro D300 averages 19637, or 0.7% lower. The AMD FirePro W7000 averages 19905, or 0.7% higher. The NVIDIA Quadro K5200 averages 19602, or 0.8% lower. While these cards may have similar synthetic scores, the RX 6650 XT brings modern features like 8 GB of GDDR6 memory, 32 ray tracing cores, and support for DirectX 12 Ultimate, which are relevant for Rust’s current rendering pipeline.

If a user were to swap either component for one of these near-equivalents, the in-game performance would likely be within a few percentage points. The data suggests that the i5-12400 and RX 6650 XT are well-matched in that neither is a bottleneck that dramatically limits the other. The CPU’s single-thread performance is adequate for Rust’s simulation logic, while the GPU’s 10.79 TFLOPS of FP32 compute and 280.3 GB/s of memory bandwidth handle the rendering load at 1080p and 1440p.

CPU and GPU Roles

The measured FPS data reveals how the balance of CPU and GPU load shifts across resolutions and presets. At 1920x1080, the system delivers 145.2 FPS on Low, 98.4 FPS on Medium, 83.9 FPS on High, and 60.2 FPS on Ultra. The gap between Low and Ultra is 85 FPS, which indicates that the GPU is the primary scaling factor as settings increase. However, even at the lowest preset, the frame rate does not exceed 145.2 FPS, suggesting that the CPU imposes an upper ceiling on performance at 1080p.

Moving to 2560x1440, the frame rates drop to 97.5 FPS on Low, 65.1 FPS on Medium, 53.5 FPS on High, and 43.5 FPS on Ultra. The scaling from Low to Ultra is now 54 FPS, which is a smaller absolute drop than at 1080p. This indicates that the GPU is becoming more stressed at higher resolution, but the CPU still has headroom. The fact that Medium stays above 60 FPS at 1440p while High falls below suggests that the GPU is the limiting factor beyond Medium settings.

At 3840x2160, the picture changes dramatically. Low settings yield 60.2 FPS, Medium drops to 41.6 FPS, High falls to 32.6 FPS, and Ultra bottoms out at 27.7 FPS. The scaling from Low to Ultra is 32.5 FPS, which is the smallest absolute drop of any resolution. This means that at 4K, the GPU is so heavily loaded that even preset changes have less impact on frame rate. The CPU is no longer the bottleneck; the RX 6650 XT’s 8 GB of VRAM and 128-bit memory bus are simply overwhelmed by the pixel count.

The data shows that at 1080p, the CPU plays a more significant role, especially at lower presets where the GPU has spare capacity. At 1440p, the balance shifts toward the GPU, and at 4K, the GPU is almost entirely responsible for the frame rate. Users with this combo should therefore prioritize GPU settings at higher resolutions, while at 1080p they can afford to push CPU-intensive settings like draw distance and entity count.

The Verdict

This PC can run Rust, but the experience depends heavily on resolution and preset selection. At 1920x1080, the system clears 60 FPS at every preset: Low (145.2 FPS), Medium (98.4 FPS), High (83.9 FPS), and Ultra (60.2 FPS). This makes 1080p the most versatile resolution for this combo, with Ultra being exactly at the playable threshold.

At 2560x1440, the system maintains 60 FPS at Low (97.5 FPS) and Medium (65.1 FPS), but falls short at High (53.5 FPS) and Ultra (43.5 FPS). Users at 1440p should stick to Medium or lower for a consistent experience above the 60 FPS threshold.

At 3840x2160, only Low settings achieve playable performance, with an average of 60.2 FPS. Medium (41.6 FPS), High (32.6 FPS), and Ultra (27.7 FPS) all fall well below the threshold. The verdict is clear: this combo is a 1080p machine for Rust, with acceptable 1440p performance at reduced settings and only marginal 4K capability at the lowest quality.

Best Settings per Resolution

At 1920x1080, the most demanding preset that stays at or above 60 FPS is Ultra, which averages 60.2 FPS. This is the highest quality setting available and hits the threshold exactly.

At 2560x1440, the best playable preset is Medium, with an average of 65.1 FPS. High falls to 53.5 FPS, so Medium is the maximum quality that sustains 60 FPS.

At 3840x2160, the only playable preset is Low, which averages 60.2 FPS. Medium drops to 41.6 FPS, so users at 4K must accept the lowest quality setting.

Measured FPS Breakdown

1920x1080:
