Rust

The Intel Core i5-12600KF and NVIDIA GeForce RTX 5090 combination was tested in Rust, a survival game released on 2018-02-07. The CPU carries a launch MSRP of $264, and the GPU carries a launch MSRP of 1,999 USD. Measured benchmark data places this combo at rank 87 out of 3723 tested combinations, with the CPU at the 79th percentile among all CPUs and the GPU at the 92nd percentile among all GPUs. The following analysis covers similar-performance alternatives, frequently asked questions, per-resolution settings guidance, a verdict on playability, a full FPS breakdown, ranking context, and the respective roles of the CPU and GPU.

Similar Performance Alternatives

The i5-12600KF achieves an average benchmark score of 27799, placing it within a tight band of comparable processors. Its nearest rivals include the Intel Core i9-10900K (average score 27872, delta -0.3%), the AMD Ryzen 5 8500GE (27712, delta +0.3%), the AMD Ryzen 7 6800U (27887, delta -0.3%), and the AMD Ryzen 7 5800X3D (27896, delta -0.3%). All four sit within 0.3% of the i5-12600KF's average score, meaning a system built with any of these CPUs would deliver nearly identical frame rates in Rust. The i5-12600KF's 10 cores and 16 threads, with a Cinebench R23 multi-core score of 23391 and a single-core score of 3302, support this equivalence; the rival CPUs are statistically indistinguishable in aggregate performance.

On the GPU side, the RTX 5090 posts an average benchmark score of 79842. Its nearest rivals are the NVIDIA Tesla P100 PCIe 16 GB (79605, delta +0.3%), the Tesla P100 PCIe 12 GB (79396, delta +0.6%), the AMD Radeon RX 6850M XT (78940, delta +1.1%), and the AMD Radeon Pro Vega 64X (80959, delta -1.4%). These deltas range from -1.4% to +1.1%, so any of these GPUs would produce FPS values within a couple of percent of the RTX 5090 in Rust. The RTX 5090's 32 GB of GDDR7 memory, 512-bit bus, and 1.79 TB/s bandwidth are not matched by the Tesla P100 or the Radeon parts, but the aggregate scores indicate that in this game's workload, the practical frame-rate difference would be small. For users seeking similar behavior, pairing the i5-12600KF with any of the listed CPU rivals and the RTX 5090 with any of the listed GPU rivals would yield nearly identical results to the measured data.

FAQ

Q: What is the playable threshold for Rust?

A: The playable threshold is 60 FPS, as defined by the benchmark database. Any preset at or above this average frame rate is considered playable.

Q: Can this combo run Rust at 4K?

A: Yes, at 3840x2160 the combo delivers 78.6 FPS on High, 92.6 FPS on Medium, and 136.7 FPS on Low. Ultra falls below the threshold at 55.8 FPS, so Ultra is not playable at 4K.

Q: What is the best settings at 1440p?

A: At 2560x1440, all four presets exceed 60 FPS. The most demanding preset that stays playable is Ultra, which delivers 99.2 FPS average.

Q: What is the best settings at 1080p?

A: At 1920x1080, all presets clear 60 FPS. Ultra is the most demanding playable preset, averaging 142 FPS.

Q: How does this combo rank among all tested systems?

A: The combo ranks 87th out of 3723 tested combinations, placing it in the upper echelon of the database. The CPU sits at the 79th percentile among all CPUs, while the GPU sits at the 92nd percentile among all GPUs.

Q: Which component is more limiting at 4K?

A: At 3840x2160 Ultra, the average FPS drops to 55.8, below the 60 FPS threshold. This indicates the GPU is the limiting factor at 4K Ultra, as the CPU's 10-core/16-thread configuration and Cinebench R23 multi-core score of 23391 provide ample headroom.

Best Settings per Resolution

At 3840x2160, the most demanding preset that stays at or above 60 FPS is High, with an average of 78.6 FPS. Medium (92.6 FPS) and Low (136.7 FPS) also clear the threshold, but High offers the highest visual quality among playable options. Ultra fails at 55.8 FPS and is not recommended at this resolution.

At 2560x1440, every preset remains playable. The most demanding preset is Ultra, which delivers 99.2 FPS average. High (130.6 FPS), Medium (151.4 FPS), and Low (202.7 FPS) all provide substantial headroom above the 60 FPS threshold.

At 1920x1080, the most demanding preset is Ultra, averaging 142 FPS. High (187 FPS), Medium (195.6 FPS), and Low (232.3 FPS) all exceed the threshold by wide margins. Ultra at 1080p is the recommended setting for maximum visual fidelity without sacrificing playability.

The Verdict

Yes, this PC can run Rust. The verdict by resolution confirms that the combo clears the 60 FPS playable threshold at multiple settings across all three tested resolutions. At 3840x2160, the playable settings are High, Medium, and Low, with the best settings being High at 78.6 FPS average. Ultra is not playable at 4K, as it drops to 55.8 FPS. At 2560x1440, all four settings are playable, with Ultra being the best at 99.2 FPS. At 1920x1080, all four settings are playable, with Ultra being the best at 142 FPS. The only configuration that fails the threshold is 4K Ultra, which falls short by a margin of 4.2 FPS. For users prioritizing frame rate over visual fidelity, 4K Low at 136.7 FPS is a strong option, while those with 1440p or 1080p displays can run the game at maximum settings without issue.

The data shows a consistent pattern: FPS decreases as resolution increases and as settings are raised. At 1080p, the range spans from 232.3 FPS on Low to 142 FPS on Ultra. At 1440p, the range is 202.7 FPS on Low to 99.2 FPS on Ultra. At 4K, the range narrows to 136.7 FPS on Low to 55.8 FPS on Ultra. The Ultra preset at 4K is the only measurement below the 60 FPS threshold.

How This Combo Ranks

This combination ranks 87th out of 3723 tested combos in Rust, meaning it outperforms the overwhelming majority of systems in the database. The CPU's percentile of 79 among all CPUs indicates it is a strong but not top-tier processor; the GPU's percentile of 92 among all GPUs places it near the top of the GPU field. The rank of 87 is driven primarily by the GPU's exceptional performance, as the CPU is merely above-average. In practical terms, this combo delivers frame rates that are playable at 4K on high settings and at 1440p and 1080p on ultra settings. The gap between this combo and the top-ranked systems is likely attributable to CPUs with higher multi-threaded scores, since the RTX 5090's GPU performance is already near the top of the database. The combo's average FPS at 1080p Ultra (142) and 1440p Ultra (99.2) place it well ahead of the median system, which would struggle to maintain 60 FPS at those settings.

CPU and GPU Roles

The division of labor between the i5-12600KF and the RTX 5090 shifts with resolution and preset. At 1920x1080, the CPU plays a more prominent role because the GPU can render frames quickly; the FPS values on Low (232.3) and Medium (195.6) are high enough that the CPU's 10 cores and 16 threads, with a Cinebench R23 multi-core score of 23391, must keep up with the GPU's output. The single-core score of 3302 indicates strong per-thread performance, which is relevant for Rust's simulation and physics workload. At this resolution, the GPU is not the bottleneck; even on Ultra, the combo delivers 142 FPS, suggesting the CPU has headroom.

At 2560x1440, the GPU's load increases. The FPS at Low drops to 202.7, and at Ultra it falls to 99.2. The CPU still provides sufficient throughput, as the drop from 1080p to 1440p at the same preset is consistent with a GPU-bound scenario. For example, at Ultra, the FPS goes from 142 at 1080p to 99.2 at 1440p, a reduction of 42.8 FPS that reflects the additional pixel workload on the GPU.

At 3840x2160, the GPU becomes the clear limiting factor. The Ultra preset drops to 55.8 FPS, below the 60 FPS threshold, while the CPU's performance remains unchanged. The GPU's 32 GB of GDDR7 memory and 1.79 TB/s bandwidth are heavily exercised at 4K, and the rendering load overwhelms the GPU's capacity at the highest settings. The Low preset at 4K (136.7 FPS) is still far above the threshold, indicating that the GPU can handle 4K when visual effects are reduced. The CPU's role at 4K is secondary; even a weaker CPU would likely produce similar FPS at Ultra, since the GPU is the bottleneck. The scaling across resolutions — from 232.3 FPS at 1080p Low to 136.7 FPS at 4K Low, and from 142 FPS at 1080p Ultra to 55.8 FPS at 4K Ultra — demonstrates that the GPU's performance degrades more steeply with resolution than the CPU's. For users targeting 4K, reducing settings from Ultra to High (78.6 FPS) or Medium (92.6 FPS) shifts the balance back to a playable state, confirming that the GPU is the component to adjust. At 1080p and 1440p, the CPU and GPU are well matched, with neither component acting as a significant bottleneck.
