Rust

The Intel Core i5-12400F paired with the NVIDIA GeForce RTX 4080 SUPER delivers a highly capable Rust experience, though the demands of 4K Ultra settings push the combination to its limits. Measured data places this combo at rank 308 out of 3723 tested configurations, putting it in the top percentile of systems for this title. The benchmark results show a clear pattern: the system crushes 1080p and 1440p with headroom to spare, while 4K requires a slight settings compromise to maintain smooth gameplay. The Core i5-12400F, with its 6 cores and 12 threads, sits at the 73rd percentile among all CPUs, while the RTX 4080 SUPER ranks at the 86th percentile among GPUs, making the graphics card the more dominant component in this pairing.

Measured FPS Breakdown

The measured frame rate data spans three resolutions and four quality presets, with average FPS recorded for each combination. At 1920x1080, the system produces outstanding results across the board. Low settings yield 204.7 FPS average, Medium climbs to 178.3 FPS, High reaches 165 FPS, and even the demanding Ultra preset maintains a strong 123 FPS average. These figures indicate that at 1080p, the RTX 4080 SUPER is barely taxed, and the i5-12400F provides ample single-thread performance, evidenced by its 1680 score in Cinebench R23 single-core and 909 in 3DMark single-thread tests.

Moving to 2560x1440, the performance remains excellent but shows the expected scaling impact. Low settings deliver 180.9 FPS average, Medium produces 132.5 FPS, High drops to 113.1 FPS, and Ultra settles at 86.6 FPS. The transition from 1080p to 1440p at Ultra settings represents roughly a 30% reduction in frame rate, from 123 FPS down to 86.6 FPS, which is consistent with the increased pixel workload. The GPU's 16 GB of GDDR6X memory and 736.3 GB/s bandwidth handle the higher resolution textures without issue.

At 3840x2160, the system encounters its first real challenges. Low settings still produce a playable 119 FPS average, Medium achieves 79.8 FPS, and High manages 67.7 FPS. However, Ultra settings drop to 49.1 FPS, falling below the 60 FPS playability threshold. This pattern demonstrates that 4K Ultra is the breaking point for this configuration, requiring either a resolution reduction or a settings downgrade to maintain smooth gameplay. The 4K results show a substantial gap between Low and Ultra, with a difference of approximately 70 FPS, highlighting how much the higher preset demands from the GPU.

Best Settings per Resolution

For 1920x1080, the best settings that maintain at least 60 FPS are Ultra, which achieves an average of 123 FPS. This is the most demanding preset available, and it clears the threshold with a comfortable margin, leaving significant headroom for demanding scenes or multiplayer server activity with many players and structures.

At 2560x1440, the best settings are also Ultra, with an average of 86.6 FPS. This exceeds the 60 FPS target by a solid margin, confirming that the combination of the i5-12400F and RTX 4080 SUPER is well-matched for high-refresh-rate 1440p gaming in Rust. The data shows that even at this higher resolution, the system has roughly 44% more performance than necessary to hit the playability threshold.

For 3840x2160, the best settings that stay at or above 60 FPS are High, producing an average of 67.7 FPS. This is a modest margin above the threshold, so players may experience occasional dips during intense moments, but the average remains playable. Ultra at 4K falls short at 49.1 FPS, meaning the most visually demanding preset is off-limits at this resolution.

FAQ

A: At 1920x1080, all presets exceed 120 FPS, with Low settings reaching 204.7 FPS and High at 165 FPS. This makes the system well-suited for high-refresh-rate monitors at 1080p.

Q: What settings should a 4K monitor owner use?

A: High settings at 3840x2160 produce 67.7 FPS, which is the best visual quality that stays above 60 FPS. Medium settings provide additional headroom at 79.8 FPS for those who prefer a larger safety margin.

Similar Performance Alternatives

Looking at the nearest rivals for the CPU, the Intel Core i5-12400F's average benchmark score of 19039 is closely matched by several alternatives. The AMD Ryzen 5 7535HS scores 19047, representing a negligible 0% difference. The Intel Core 3 201E scores 19056, which is 0.1% lower. The Intel Core i5-1335U scores 18982, a 0.3% difference, and the AMD EPYC 7773X scores 18979, also 0.3% different. These processors would behave nearly identically to the i5-12400F in Rust, given their similar aggregate performance, though the i5-12400F's 73rd percentile ranking indicates it outperforms the majority of CPUs.

For the GPU, the NVIDIA GeForce RTX 4080 SUPER has an average benchmark score of 54209, sitting at the 86th percentile. Its closest rival is the NVIDIA GeForce RTX 4080 with a score of 54247, a 0.1% difference, meaning the two cards are effectively interchangeable in performance. The AMD Radeon Pro W5700X scores 54828, 1.1% higher, while the AMD Radeon RX 6750 GRE 12 GB scores 55698, representing a 2.7% advantage. The AMD Radeon 8060S scores 55757, 2.8% higher. These rivals would produce very similar frame rates in Rust, with the differences being within a few percent.

CPU and GPU Roles

The benchmark data reveals distinct scaling patterns that illuminate which component matters more at each resolution. At 1920x1080, the CPU's influence is relatively more significant, as the GPU has ample headroom. The difference between Low and Ultra at 1080p is 81.7 FPS (from 204.7 down to 123), showing that settings changes scale the workload but the system remains GPU-bound at higher presets. The i5-12400F's strong single-thread performance, with a Passmark single-thread score of 3481, ensures the CPU does not bottleneck the GPU at this resolution.

At 2560x1440, the GPU begins to take on a more dominant role. The scaling from 1080p to 1440p at Ultra settings shows a 29.6% decrease in FPS (from 123 to 86.6), which aligns with the increased pixel count. The CPU's role diminishes as the GPU becomes more saturated, though the i5-12400F's 12 threads still provide adequate feeding. The 3DMark 16-thread score of 5895 and Cinebench R23 multi-core score of 12380 indicate the CPU has sufficient multi-threaded capability for the game's simulation and entity tracking.

At 3840x2160, the GPU is clearly the limiting factor. The scaling from 1440p to 4K at Ultra shows a 43.3% reduction in FPS (from 86.6 to 49.1), which is more severe than the pixel count increase would suggest, indicating the GPU is fully saturated. The CPU's role becomes secondary at this resolution, as the RTX 4080 SUPER's 52.22 TFLOPS of FP32 performance and 816.0 GTexel/s texture rate are the determining factors. The 4K results show that even a strong CPU like the i5-12400F cannot compensate for the GPU's workload at this resolution.

The Verdict

This PC can absolutely run Rust, and it does so exceptionally well at most settings. The verdict by resolution confirms that the system clears the 60 FPS threshold at all playable settings for 1920x1080 and 2560x1440, with the best settings being Ultra in both cases, achieving 123 FPS and 86.6 FPS respectively. At 3840x2160, the system remains playable on High, Low, and Medium settings, with High being the best playable option at 67.7 FPS. The only configuration that fails the 60 FPS test is 4K Ultra, which produces 49.1 FPS.

For players with a 1080p or 1440p monitor, this combination offers a flawless Rust experience with maximum graphical fidelity and high frame rates. The RTX 4080 SUPER's 16 GB of VRAM ensures future-proofing for texture-heavy updates, while the i5-12400F's 6 cores and 12 threads handle the game's server-side calculations and entity management without issue. At 4K, the system still delivers a smooth experience on High settings, though players seeking maximum visual quality would need to accept the frame rate drop below 60 FPS or consider a more powerful GPU. Overall, the data shows this is a top-tier configuration for Rust, ranking in the top 8.3% of all tested combos, and it provides an excellent balance of CPU and GPU performance for this demanding survival title.
