Rust

The AMD Ryzen 5 7400F and NVIDIA GeForce RTX 3080 combination delivers a substantial performance envelope for Rust, but its playability is heavily dictated by resolution and settings. The data shows a system that can dominate at 1080p, remain highly capable at 1440p, but struggles to maintain smooth frame rates at 4K with higher presets. This analysis breaks down the measured performance, contextualizes it against similar hardware, and provides clear guidance on how to get the most out of this pairing.

Similar Performance Alternatives

Looking at the CPU's nearest rivals, the Ryzen 5 7400F sits in a tight cluster of processors. Its average benchmark score of 32750 is nearly identical to the Intel Core i5-14600T, which scores 32707 (a delta of just 0.1%). The AMD Ryzen 7 PRO 6850H is the only close competitor that edges it out, with a score of 32812, representing a -0.2% delta for the 7400F. The Intel Core Ultra 7 155H (32697) and AMD Ryzen AI 7 PRO 360 (32662) are also within 0.3% of the 7400F's score. What this implies is that from a pure compute standpoint, swapping the 7400F for any of these four chips would yield virtually indistinguishable frame rates in Rust, as the game's engine is unlikely to differentiate between processors with such marginal average score differences.

On the GPU side, the RTX 3080's nearest rivals are an eclectic group. The NVIDIA P106-100, AMD Radeon Pro Vega 16, AMD Radeon RX 6600M, and AMD Radeon R9 M290X all have average scores within 0.4% of the 3080's 23172. This is a curious grouping, as these cards span different generations and market segments. The data suggests that in raw benchmark terms, the RTX 3080's performance is bracketed by these four GPUs, but the RTX 3080's 10 GB of GDDR6X memory and 760.3 GB/s bandwidth give it a distinct advantage in modern titles like Rust that are sensitive to memory capacity and bandwidth. The deltaPct values are all negative (ranging from -0.3% to -0.4%), meaning the 3080 scores slightly lower than these rivals in the aggregate benchmark, yet the measured FPS in Rust tells a different story—one where the 3080's architectural strengths come to the fore.

CPU and GPU Roles

Rust is a game that stresses both the CPU and GPU, but the measured FPS scaling across resolutions reveals which component becomes the bottleneck. At 1920x1080, the jump from Low to Ultra settings sees average FPS drop from 216 to 93, a massive 123 FPS swing that indicates the GPU is doing the heavy lifting as settings increase. However, the fact that even at Low settings the game never exceeds 216 FPS suggests the CPU is not the limiting factor at this resolution; the Ryzen 5 7400F's six Zen 4 cores with 32 MB of shared L3 cache are more than sufficient to feed the RTX 3080.

Moving to 2560x1440, the pattern holds. Low settings produce 148 FPS, while Ultra drops to 64 FPS. The scaling from 1080p Low (216 FPS) to 1440p Low (148 FPS) represents a 31% reduction, which is primarily a GPU-bound penalty from the increased pixel count. At Ultra settings, the 1440p score of 64 FPS is 31% lower than the 1080p Ultra score of 93 FPS, again pointing to GPU dominance. The CPU's role becomes more apparent at 3840x2160, where even Low settings only yield 88 FPS—a 59% drop from 1080p Low. This steeper decline at 4K indicates that while the GPU is still the primary bottleneck, the CPU's single-thread performance (Cinebench R23 single-core score of 3072) is being pushed harder to maintain draw calls and physics calculations at higher resolutions.

The preset scaling within each resolution reinforces this. At 1080p, the difference between Low and Ultra is 123 FPS (216 to 93). At 1440p, it's 84 FPS (148 to 64). At 4K, it's 50 FPS (88 to 38). This shrinking delta as resolution increases is a classic sign of GPU-bound performance, where the RTX 3080's workload becomes so heavy that settings adjustments have diminishing returns. For this game, the GPU is the dominant factor at all resolutions, but the CPU's strong single-core showing ensures it never becomes a severe bottleneck, even at 4K.

Measured FPS Breakdown

At 1920x1080, the RTX 3080 and Ryzen 5 7400F combination produces excellent results across all presets. Low settings average 216 FPS, which is far beyond what any 60 Hz or 144 Hz monitor can display. Medium settings average 145 FPS, with a minimum of 123 FPS and maximum of 166 FPS, indicating smooth frame pacing even during intense moments. High settings average 122 FPS, still comfortably above the playable threshold. Ultra settings average 93 FPS, which is a 23% reduction from High but still well within the range of high-refresh-rate gaming. The data shows no frame drops below 60 FPS at this resolution, even at the most demanding preset.

At 2560x1440, performance remains strong but the impact of higher resolution is clear. Low settings average 148 FPS, which is a 31% drop from the 1080p Low score. Medium settings average 100 FPS, with a minimum of 85 FPS and maximum of 115 FPS—the minimum is still well above the 60 FPS playable threshold. High settings average 84 FPS, which is a 31% reduction from the 1080p High score of 122 FPS. Ultra settings average 64 FPS, which is exactly at the edge of the playable threshold, with the data suggesting occasional dips below that mark based on the pattern seen at other settings. The 1440p Medium preset offers the best balance, with a minimum FPS of 85 that provides a comfortable margin.

At 3840x2160, the picture changes dramatically. Low settings average 88 FPS, which is playable but represents a 59% drop from 1080p Low. Medium settings average 59 FPS, with a minimum of 50 FPS and maximum of 68 FPS—the average is just below the 60 FPS playable threshold, and the minimum dips to 50 FPS, indicating noticeable stutters. High settings average 50 FPS, which is not playable by the 60 FPS standard. Ultra settings average 38 FPS, which is the worst-case scenario and clearly not suitable for smooth gameplay. The data reveals that 4K is only viable with Low settings for this combination.

Best Settings per Resolution

At 1920x1080, the most demanding preset that stays at or above 60 FPS is Ultra, with an average of 93 FPS. This is the highest quality setting available and it still delivers a frame rate well above the playable threshold, making 1080p Ultra the recommended configuration for this resolution.

At 2560x1440, Ultra settings also pass the 60 FPS mark with an average of 64 FPS. This is the most demanding playable preset, but the slim margin above 60 FPS means users who prioritize consistent frame pacing might prefer Medium, which offers a 100 FPS average and an 85 FPS minimum.

At 3840x2160, the only preset that stays at or above 60 FPS is Low, with an average of 88 FPS. Medium settings fall to 59 FPS, which is just below the threshold, so Low is the sole playable option at 4K. The data indicates that 4K gaming with this combo requires significant graphical compromises.

How This Combo Ranks

The AMD Ryzen 5 7400F and NVIDIA GeForce RTX 3080 combination ranks 998 out of 3723 tested combos in Rust, placing it in the top 27% of all systems tested. This percentile ranking is notable because the RTX 3080's individual GPU percentile is 68 (meaning it outperforms 68% of all GPUs), while the CPU's percentile is 83. The combo rank of 998 suggests that while both components are individually strong, the pairing doesn't boost to the top tier of Rust performance, likely due to the game's heavy reliance on single-threaded CPU performance and the GPU's 10 GB memory capacity being a potential limitation at higher resolutions.

The rank also implies that there are 2,725 other tested combinations that outperform this setup in Rust, which is a significant number. However, the measured FPS data shows that this combo still delivers playable performance at 1080p and 1440p across all presets, and the 998 rank should be viewed in the context of the game's demanding nature rather than as a reflection of poor hardware. The data indicates that this system is a solid mid-to-high-tier performer, but not an elite one.

The Verdict

This PC can run Rust, but the experience varies dramatically by resolution and settings. At 1920x1080, all four presets (Low, Medium, High, Ultra) deliver average FPS well above the 60 FPS threshold, with Ultra averaging 93 FPS. This resolution is fully playable at maximum quality. At 2560x1440, all presets also clear the 60 FPS mark, with Ultra averaging 64 FPS, making 1440p playable at every settings level, though Ultra is close to the boundary. At 3840x2160, only Low settings achieve playable performance with an 88 FPS average; Medium falls just short at 59 FPS, while High (50 FPS) and Ultra (38 FPS) are not playable.

The verdictByResolution data confirms this: 1080p and 1440p support all settings, with Ultra being the best playable preset in both cases (93 FPS and 64 FPS respectively). For 4K, Low is the only playable setting, yielding 88 FPS. This system is best suited for 1080p and 1440p gaming, where it can handle Rust at maximum quality with smooth frame rates. At 4K, the RTX 3080's 10 GB memory and the CPU's performance limits force a compromise to Low settings, which still provides a playable but visually reduced experience.
