Rust

The short answer is a qualified yes: the Core i5-12400 and Radeon RX 580 can run Rust, but only at 1080p on Low settings does the pairing clear the 60 FPS threshold. Every other resolution and preset combination in the database falls short, some by wide margins. The recorded measurements show a configuration best treated as a 1080p Low-settings machine for this particular survival title.

Measured FPS Breakdown

All numbers below are measured averages from the database; minimum and maximum frame rates were not recorded for these runs, so averages are the basis of every verdict here.

At 1920x1080, the results form a clear ladder. Low settings deliver 73.2 FPS, the only result in the entire dataset above the 60 FPS playable threshold. Medium drops to 50.1 FPS, High falls further to 44.1 FPS, and Ultra lands at just 29.7 FPS, roughly half of what Low manages and less than a third of the way to a comfortable 60 FPS target at that preset. The gap between Low and Medium is 23.1 FPS, the single largest settings step at this resolution, which tells you image-quality concessions buy a lot of performance with this graphics card.

At 2560x1440, the RX 580 runs out of headroom. Low settings manage 50.1 FPS, interestingly identical to the 1080p Medium figure, and below the threshold. Medium sits at 32.7 FPS, High at 30.8 FPS, and Ultra at 24.7 FPS. Note how compressed the Medium-to-High spread becomes here, only 1.9 FPS separates them, which indicates the GPU is fully saturated and settings tweaks no longer recover meaningful performance at this resolution.

At 3840x2160, the combination is simply outclassed. Low produces 32.5 FPS, Medium 19.4 FPS, High 17.9 FPS, and Ultra 13.1 FPS. Even the most aggressive quality reduction cannot reach half of the 60 FPS target. Four-K gaming in Rust is not on the menu for this hardware.

How This Combo Ranks

Within the database's tested configurations for Rust, the Core i5-12400 plus RX 580 pairing ranks 3384 out of 3723 combos. That places it in the bottom tenth of tested setups for this game, despite the CPU itself being a reasonably capable part. The rank is dragged down almost entirely by the graphics card: the RX 580 sits at the 53rd percentile of all GPUs in the database, which sounds middling, but Rust at higher resolutions punishes weaker cards hard, and the measured frame rates confirm that.

For context on the CPU side, the i5-12400 sits at the 72nd percentile versus all CPUs, with an average benchmark score of 18683. Its nearest rivals by aggregate score are a diverse set: the AMD EPYC 7643 at 18697 (a fraction of a percent ahead), the Intel Core i7-1355U at 18730, the AMD Ryzen AI 5 330 at 18811, and the Intel Core i3-14100F at 18519, which scores slightly lower. The fact that a six-core desktop chip rubs shoulders with a big server CPU and modern mobile parts in aggregate terms underlines that the processor is not the weak link in this pairing.

FAQ

Q: Can the i5-12400 and RX 580 run Rust at 60 FPS?

A: Yes, but only in one configuration: 1920x1080 at Low settings, where the measured average is 73.2 FPS. No other resolution and preset combination in the database reaches 60 FPS.

Q: What is the best-looking setting this combo can use while staying playable?

A: Low at 1080p. Medium at 1080p averages 50.1 FPS, which misses the 60 FPS threshold, so Low is the ceiling for a playable experience.

Q: Can this setup handle 1440p?

A: Not at the 60 FPS standard. The best 2560x1440 result is 50.1 FPS on Low, with Ultra falling to 24.7 FPS. Players tolerant of lower frame rates could manage Low settings, but the data does not support calling it playable.

Q: Is 4K possible at all?

A: No. Even at Low settings, 3840x2160 averages 32.5 FPS, and Ultra drops to 13.1 FPS.

Q: Which component is holding this pairing back?

A: The GPU. The i5-12400 ranks in the 72nd percentile of all CPUs, while the RX 580 sits at the 53rd percentile of all GPUs, and the frame-rate scaling across resolutions points squarely at graphics-side saturation.

Q: Does lowering settings help significantly?

A: At 1080p, yes: dropping from Ultra to Low more than doubles the frame rate, from 29.7 to 73.2 FPS. At 1440p and 4K the benefit shrinks because the GPU is already saturated.

Similar Performance Alternatives

Judging by the nearest rivals recorded in the database, several GPUs would behave nearly identically to the RX 580 in this game. The NVIDIA GeForce RTX 3050 Ti Mobile averages 12940 versus the RX 580's 12928, essentially a dead heat. The NVIDIA GeForce GTX 1660 SUPER is marginally ahead at 12986, a difference of well under one percent. On the AMD side, the Radeon 740M (12870) and the FirePro W5100 (12847) land within a fraction of a percent below. Anyone running a GTX 1660 SUPER or an RTX 3050 Ti Mobile should expect Rust performance within a rounding error of the numbers on this page.

On the CPU side, the i5-12400's aggregate score of 18683 is matched by the AMD EPYC 7643 at 18697, the Intel Core i7-1355U at 18730, the AMD Ryzen AI 5 330 at 18811, and the Intel Core i3-14100F at 18519. Since the GPU is the bottleneck in Rust for this pairing, any of these processors paired with a similar-class card would produce comparable frame rates. Notably, the more modest i3-14100F would likely deliver nearly the same Rust experience when matched with an RX 580-class GPU.

CPU and GPU Roles

The scaling data makes the division of labor obvious. Going from 1080p Low (73.2 FPS) to 1440p Low (50.1 FPS) costs 23.1 FPS, a drop of nearly a third, purely from increasing the pixel count. At 4K Low the figure falls to 32.5 FPS. Frame rate falling steeply as resolution rises is the classic signature of a GPU-bound game, and it means the RX 580, not the i5-12400, sets the performance ceiling at every resolution tested.

The settings scaling reinforces this. At 1080p, preset changes still move the needle significantly, from 73.2 FPS on Low down to 29.7 FPS on Ultra, so the GPU has some slack at the lowest resolution. By 1440p, Medium (32.7 FPS) and High (30.8 FPS) are nearly indistinguishable, and at 4K the curve flattens completely across High (17.9), Medium (19.4), and Ultra (13.1). Once the card saturates, quality settings stop mattering.

The CPU's contribution shows up indirectly. The i5-12400 brings six cores and twelve threads with a 4.40 GHz boost clock, a single-thread Passmark score of 3456, and a Cinebench R23 single-core result of 2257, all comfortably adequate for a survival title released in 2018. The database contains no evidence of a CPU ceiling here: if the processor were limiting, Low settings at 1080p would plateau below the GPU's capability, and the 73.2 FPS result would not scale so cleanly against the preset ladder. For Rust specifically, the verdict is unambiguous: at 1080p the GPU is mostly in charge, and at 1440p and 4K it is entirely in charge.

The Verdict

Can this PC run Rust? Yes, with one strict condition. At 1920x1080 on Low settings the pairing averages 73.2 FPS and clears the 60 FPS bar with room to spare, so a playable experience exists. At 1080p Medium (50.1 FPS) and above, at every 1440p preset (topping out at 50.1 FPS on Low), and at every 4K preset (topping out at 32.5 FPS on Low), the configuration misses the threshold, and the database records no playable settings at either higher resolution.

The practical takeaway is straightforward. This is a 1080p Low-settings rig for Rust, full stop. The Core i5-12400 has plenty of processor left in reserve for this game, and anyone wanting higher presets or higher resolutions would need to address the graphics card first, since the RX 580 is the component defining every frame-rate ceiling recorded here.
