Rust

The pairing of Intel's Core i5-12400 with NVIDIA's GeForce RTX 5070 is a study in generational asymmetry: a mid-range Alder Lake CPU from early 2022 feeding a Blackwell 2.0 GPU released in 2025. The question for Rust players is whether that six-core, twelve-thread processor bottlenecks a card with 6144 shading units and 12 GB of GDDR7. Benchmark data for this exact combination shows the answer is largely no — Rust runs comfortably at 1080p and 1440p, and remains playable at 4K with settings dialed back. With a launch MSRP of $199 for the CPU and 549 USD for the GPU, this is a measured analysis of how the combo actually performs in Facepunch's survival title, which has been demanding on hardware since its 2018 release.

Measured FPS Breakdown

The dataset covers three resolutions and four presets, with average figures for all twelve configurations and full min/avg/max data captured at Medium settings.

At 1920x1080, the combo is fast across the board. Low preset averages 203 FPS. Medium averages 161 FPS with a minimum of 137 and a maximum of 186. High averages 136 FPS, and even Ultra holds a 104 FPS average. Every preset clears the 60 FPS playability threshold with enormous headroom — the slowest configuration at this resolution is still well above what most displays require.

At 2560x1440, the numbers step down but remain strong. Low averages 165 FPS, Medium averages 111 FPS with a floor of 94 and a ceiling of 128, High averages 94 FPS, and Ultra averages 71 FPS. Note the Medium minimum of 94 FPS: even frame-time dips during intense scenes keep this pairing comfortably in high-refresh territory at 1440p.

At 3840x2160, the GPU begins to feel the pixel load. Low averages 98 FPS, Medium averages 66 FPS with a minimum of 56 and a maximum of 75, High drops to 55 FPS, and Ultra falls to 42 FPS. The Medium minimum of 56 is worth attention — it dips below the 60 FPS threshold at the worst moments, meaning 4K Medium is playable on average but not guaranteed frame-perfect under load.

The min/max data at Medium settings tells a consistent story about frame consistency: a spread of roughly 49 FPS at 1080p (137 to 186), 34 FPS at 1440p (94 to 128), and 19 FPS at 4K (56 to 75). The tighter spread at higher resolutions reflects the shift toward GPU limitation, where frame times stabilize as the graphics card becomes the constraint.

CPU and GPU Roles

The scaling data reveals where the bottleneck sits at each resolution. From 1080p to 1440p at Medium settings, average FPS falls from 161 to 111 — a drop of about 31 percent for a 78 percent increase in pixel count. From 1440p to 4K, it falls from 111 to 66, again a modest decline relative to the pixels added. This shallow scaling curve is the classic signature of a GPU-bound configuration: the RTX 5070 is working harder with each resolution step while the Core i5-12400's load barely changes.

Further evidence comes from the preset scaling at 1080p. Moving from Ultra to Low only lifts the average from 104 to 203 FPS. If the CPU were the limiting factor, lowering graphical settings would produce a much smaller gain, because the processor would cap the ceiling regardless of what the GPU renders. Instead, the near-doubling of frame rate shows the i5-12400 can feed Rust's engine well past 200 FPS at this resolution.

At 4K, the GPU is unambiguously the constraint — Ultra manages only 42 FPS while the same preset runs at 104 FPS at 1080p. The Core i5-12400, with its 2.50 GHz base and 4.40 GHz boost clocks, six performance cores, and 18 MB of shared L3 cache, sits in the 72nd percentile of all tested CPUs. Its single-thread results (910 in 3DMark single-thread, 2257 in Cinebench R23 single-core) indicate enough per-core throughput for Rust, a game that leans on a primary thread for much of its simulation. The data indicates that for this game and this GPU, the processor only becomes conversationally relevant at very high 1080p frame rates.

How This Combo Ranks

Against the full database, the i5-12400 + RTX 5070 pairing ranks 730th out of 3723 tested combinations in Rust. That places it in roughly the top fifth of configurations measured for this game — a solid standing for a build whose CPU launched at $199. The rank is consistent with the component-level percentiles: the RTX 5070 sits in the 82nd percentile of all GPUs with an average benchmark score of 40377, while the i5-12400 sits in the 72nd percentile of CPUs with an average score of 18683. The GPU is the stronger half of this duo by percentile, which matches the measured behavior — the GPU determines the performance ceiling in Rust here, and the CPU rarely intrudes on it.

FAQ

Q: Can this combo run Rust at 4K?

A: Yes, but not at every preset. Measured data shows 4K is playable at Low (98 FPS average) and Medium (66 FPS average), while High (55 FPS) and Ultra (42 FPS) fall short of the 60 FPS threshold. Medium is the recommended ceiling at 3840x2160.

Q: Does the Core i5-12400 bottleneck the RTX 5070 in Rust?

A: The data says no at mainstream resolutions. At 1080p Medium, the combo averages 161 FPS, and lowering settings to Low raises the average to 203 FPS — a gain the CPU would block if it were the limiting factor. The GPU is the primary constraint at 1440p and 4K.

Q: What is the highest frame rate measured for this pairing?

A: 203 FPS average, at 1920x1080 on the Low preset. At 2560x1440 Low, the combo still averages 165 FPS.

Q: Which presets stay above 60 FPS at 1440p?

A: All of them. Low (165), Medium (111), High (94), and Ultra (71) all clear the 60 FPS threshold at 2560x1440, making Ultra a viable default at that resolution.

Q: How consistent are frame times in Rust on this hardware?

A: The Medium-preset min/max data indicates good consistency. At 1440p, frames range from a 94 FPS minimum to a 128 FPS maximum — the worst dip still exceeds the playability threshold by a wide margin. At 4K Medium, the minimum of 56 FPS briefly dips below 60.

Q: How does this combination rank against other tested setups?

A: It ranks 730th out of 3723 combinations measured in Rust, placing it in the top fifth of the database for this game.

Similar Performance Alternatives

For CPUs, the nearest rivals to the Core i5-12400 by average score are a varied set: the AMD EPYC 7643 (avgScore 18697, within 0.1 percent), the Intel Core i7-1355U (18730, within 0.3 percent), the AMD Ryzen AI 5 330 (18811, within 0.7 percent), and the Intel Core i3-14100F (18519, 0.9 percent behind). On aggregate benchmark throughput, any of these processors sits within a fraction of a percent of the i5-12400, and in a GPU-bound title like Rust at 1440p and 4K, the database indicates they would behave near-identically behind the same RTX 5070. The i3-14100F is the most direct like-for-like alternative as another affordable desktop Intel part.

For GPUs, the closest rivals to the RTX 5070 by average score are the AMD Radeon Pro 580 (avgScore 40318, within 0.1 percent), the AMD Radeon Pro WX 7100 (40063, within 0.8 percent), the AMD Radeon Pro 5300 (40870, 1.2 percent ahead), and the NVIDIA RTX A500 Mobile (39568, 2 percent behind). These scores cluster remarkably tightly around the 5070's 40377 average, suggesting comparable overall compute throughput — though the 5070's Blackwell 2.0 feature set, including 48 RT cores and 192 tensor cores, is unique to it in this group. In terms of raw Rust frame delivery at these scores, the data indicates the Radeon Pro 5300 would land slightly ahead and the RTX A500 Mobile slightly behind the RTX 5070 in this pairing class.

Best Settings per Resolution

• 1920x1080 — Ultra, 104 FPS average. Every preset is playable, so there is no reason to compromise. Ultra more than clears 60 FPS with headroom to spare.
• 2560x1440 — Ultra, 71 FPS average. The full settings stack is playable here too. Ultra's 71 FPS average sits comfortably above the threshold, and Medium's floor of 94 FPS shows how much safety margin exists one notch down.
• 3840x2160 — Medium, 66 FPS average. This is the ceiling at 4K. High (55 FPS) and Ultra (42 FPS) fall below the playability line, while Medium holds above it on average — though its 56 FPS minimum means occasional dips under 60 during heavy scenes. Players sensitive to dips can drop to Low for a 98 FPS average.
