Rust

The pairing of a six-core, twelve-thread Intel Core i5-10400F with an AMD Radeon RX 6650 XT raises a fair question for Rust, a survival game that released in 2018 and has grown steadily more demanding since. The database contains measured frame rates for this exact combination across 1080p, 1440p, and 4K at four presets, and the recorded data paints a clear picture: comfortable performance at 1080p at every quality tier, playable results at 1440p with settings discipline, and a narrow path to 60 FPS at 4K only on Low.

Best Settings per Resolution

The playable threshold in this dataset is 60 FPS average, and each resolution has one preset that sits at the demanding end of what still clears that bar.

At 1920x1080, the answer is Ultra, averaging 60.7 FPS. Every preset below it runs faster, from High at 79 FPS down to Low at 142.9 FPS. At 2560x1440, Medium is the ceiling, averaging 69 FPS, while High falls to 54.7 FPS and misses the mark. At 3840x2160, only Low qualifies, at 60.5 FPS. Medium at 4K averages 40.4 FPS and High averages 31.6 FPS, both well short of the threshold.

The pattern is a clean one: each step up in resolution costs roughly one full quality tier. The settings headroom that exists at 1080p, where even the top preset scrapes past 60, is entirely spent by the time the pixel count quadruples.

CPU and GPU Roles

The scaling data suggests this game leans on the GPU far more than the CPU in this configuration. Consider what happens when resolution rises from 1920x1080 to 2560x1440 at Ultra: the average drops from 60.7 FPS to 45.6 FPS. At Low, the same resolution change takes frame rates from 142.9 FPS to 101.6 FPS. If the Core i5-10400F were the limiting factor, raising resolution would barely dent performance, because the CPU workload is largely resolution-independent. Instead, frame rates fall sharply in every case, which points to the RX 6650 XT as the component doing the heavy lifting and, at higher resolutions, the component that gives out first.

There is a hint of CPU influence at the low end, though. At 1080p Low, the average of 142.9 FPS is high but not extreme for a GPU of this class, and the i5-10400F's single-thread results (a Passmark single-thread score of 2541 and a Geekbench single-core score of 1420) suggest the processor sits in the 68th percentile of all CPUs in the database. That is solid but not elite, and Rust's simulation-heavy survival gameplay could plausibly cap the very top of the frame-rate range. Still, at the settings most players will actually use, the RX 6650 XT, sitting in the 65th percentile of all GPUs, is the deciding component.

The preset scaling tells the same story from the other direction. Dropping from High to Low at 1080p nearly doubles performance, from 79 FPS to 142.9 FPS, which is the signature of a fill-rate-bound workload rather than a CPU-bound one.

How This Combo Ranks

Within the database's measured Rust configurations, this CPU and GPU pairing ranks 2374 out of 3723 tested combinations. That places it below the midpoint, in roughly the bottom third, which initially seems surprising given that 1080p Ultra averages 60.7 FPS. The likely explanation is the composition of the leaderboard: Rust attracts a very wide spread of hardware, and many faster combinations crowd the upper ranks. For this pairing, the ranking is less a condemnation and more a reminder that the game scales well with stronger GPUs, leaving room above.

Viewed component by component, the CPU sits in the 68th percentile with an average benchmark score of 14185, and the GPU sits in the 65th percentile with an average benchmark score of 19765. Neither part is an outlier, and their combined ranking in Rust reflects exactly that: a mid-pack machine with mid-pack results, strong enough at 1080p, stretched at 4K.

Similar Performance Alternatives

The CPU's nearest rivals by aggregate score are an unusual mix: the Intel Xeon 6756E at 14163 average (a delta of just 0.2 percent), the Intel Core 7 160UL at 14232 (minus 0.3 percent), the AMD EPYC 7552 at 14115 (plus 0.5 percent), and the AMD Ryzen 3 7320C at 14277 (minus 0.6 percent). All four are within a fraction of a percent of the i5-10400F in overall benchmark terms, so any of them paired with the same GPU would be expected to produce Rust frame rates within a hair of these numbers, though their differing core and thermal characteristics mean real-world consistency may vary.

On the GPU side, the RX 6650 XT's closest rivals by average score are the NVIDIA Tesla K40m at 19885 (minus 0.6 percent), the AMD FirePro D300 at 19637 (plus 0.7 percent), the AMD FirePro W7000 at 19905 (minus 0.7 percent), and the NVIDIA Quadro K5200 at 19602 (plus 0.8 percent). These are workstation and compute parts whose aggregate scores happen to land near the RX 6650 XT's 19765, and their gaming behavior in Rust would not necessarily mirror these deltas. The safer takeaway is that any GPU whose database average lands in this narrow band should deliver broadly similar Rust performance when paired with a comparable processor.

Measured FPS Breakdown

All figures below are measured averages; minimum and maximum frame rates were not recorded for these runs.

1920x1080:

• Low: 142.9 FPS average
• Medium: 97.1 FPS average
• High: 79 FPS average
• Ultra: 60.7 FPS average

2560x1440:

• Low: 101.6 FPS average
• Medium: 69 FPS average
• High: 54.7 FPS average
• Ultra: 45.6 FPS average

3840x2160:

• Low: 60.5 FPS average
• Medium: 40.4 FPS average
• High: 31.6 FPS average
• Ultra: 24.9 FPS average

Two details stand out. First, 1080p Ultra at 60.7 FPS and 4K Low at 60.5 FPS are separated by a rounding error, a neat illustration of the one-tier-per-resolution tradeoff. Second, the Ultra preset is punishing at higher resolutions: 24.9 FPS at 4K is less than half the playable threshold, and no amount of CPU headroom would rescue that number. The Medium preset offers the most balanced experience at 1440p, holding 69 FPS average, a 13 FPS cushion over the threshold that absorbs dips better than High's 54.7 FPS, which already sits below the line.

The Verdict

Yes, this PC can run Rust, with qualifications that depend entirely on resolution. At 1920x1080, all four presets are playable, Low, Medium, High, and Ultra, with Ultra at 60.7 FPS marking the ceiling. At 2560x1440, Low and Medium clear 60 FPS, with Medium at 69 FPS as the best playable choice, while High at 54.7 FPS and Ultra at 45.6 FPS fall short. At 3840x2160, only Low qualifies, at 60.5 FPS, and that margin of just half a frame over the threshold means any scene complexity spike could dip below 60.

The practical recommendation embedded in the data: play at 1080p if visual quality matters most, at 1440p Medium if the balance of image quality and frame rate matters most, and treat 4K Low as a demonstration of what is barely possible rather than a recommended configuration. For a survival game where sustained, consistent frame rates matter during combat and base defense, the 1080p Medium to High range, at 97.1 and 79 FPS average respectively, provides the most comfortable cushion above the threshold.

FAQ

Q: Can the i5-10400F and RX 6650 XT run Rust at 4K?

A: Only barely. The single playable preset at 3840x2160 is Low, averaging 60.5 FPS, just above the 60 FPS threshold. Medium averages 40.4 FPS, High 31.6 FPS, and Ultra 24.9 FPS.

Q: What is the best-looking setting for 60 FPS Rust gameplay on this PC?

A: 1080p Ultra, which averages 60.7 FPS. If a larger frame-rate cushion is preferred, 1080p High averages 79 FPS and 1080p Medium averages 97.1 FPS.

Q: Is 1440p viable for Rust with this hardware?

A: Yes, at Low and Medium. Medium averages 69 FPS and Low averages 101.6 FPS, while High at 54.7 FPS and Ultra at 45.6 FPS do not reach the playable threshold.

Q: Does Rust favor the CPU or the GPU in this configuration?

A: The GPU. Frame rates drop sharply as resolution rises at every preset, for example Ultra falls from 60.7 FPS at 1080p to 45.6 FPS at 1440p, which indicates the RX 6650 XT is the limiting component rather than the Core i5-10400F.

Q: How does this combination rank among tested Rust setups?

A: It ranks 2374 out of 3723 measured combinations in the database, below the midpoint, despite mid-pack individual percentile placements: 68th for the CPU and 65th for the GPU.

Q: How much performance does lowering settings buy at 1080p?

A: A lot. Dropping from Ultra to Low raises the average from 60.7 FPS to 142.9 FPS, more than doubling frame rates, which reflects a GPU fill-rate-bound workload.
