Rust

The Intel Core i5-12400 paired with the NVIDIA GeForce RTX 5070 delivers a highly playable Rust experience across the board, but the performance scaling reveals a system that is heavily dependent on graphics settings. At 1080p, the combination is capable of pushing frame rates well beyond the territory of high-refresh-rate monitors, while 4K Ultra settings bring the system to its knees. The data indicates that this is a balanced pairing where the GPU becomes the primary bottleneck at higher resolutions and settings, but the CPU’s six Performance cores hold their own at lower resolutions.

Resolution Scaling

The measured FPS data shows a classic resolution scaling curve that highlights the shifting bottleneck between the CPU and GPU. Moving from 1920x1080 to 2560x1440 on Low settings, the average frame rate drops from 203 FPS to 165 FPS, a 18.7% reduction. This relatively modest decrease suggests that at these settings, the Intel Core i5-12400 is still feeding the GPU effectively, and the performance is not entirely GPU-bound. However, pushing further to 3840x2160 on Low settings results in an average of 98 FPS, a steep 51.7% drop from the 1440p figure. This dramatic falloff clearly indicates that the RTX 5070’s rendering capabilities are the limiting factor at 4K, as the pixel count overwhelms the GPU’s shading units and memory bandwidth.

The scaling pattern becomes even more pronounced when examining higher settings. At High settings, the transition from 1080p to 1440p sees a drop from 136 FPS to 94 FPS (a 30.9% decrease), and then a further reduction to 55 FPS at 4K (a 41.5% drop from 1440p). The 4K High result of 55 FPS is nearly half the 1080p High result, demonstrating that the game’s visual effects at High settings significantly increase the GPU workload. The Medium settings row provides additional insight, with 4K showing an average of 66 FPS with a minimum of 56 FPS and a maximum of 75 FPS, while 1440p Medium averages 111 FPS (min 94, max 128) and 1080p Medium averages 161 FPS (min 137, max 186). These figures suggest that Medium settings at 4K are the threshold for maintaining a stable 60 FPS experience, as the minimum FPS of 56 indicates occasional dips below that target.

The RTX 5070’s 12 GB of GDDR7 memory and 672.0 GB/s of bandwidth are likely the key enablers for 4K performance, but the data shows that even this hardware cannot maintain high frame rates at 4K Ultra. The 4K Ultra average of 42 FPS is the lowest recorded result across the entire matrix, and it represents a 62.5% drop from the 1080p Ultra average of 104 FPS. This indicates that Rust’s Ultra preset at 4K is simply too demanding for this GPU, pushing it beyond its comfortable operating range. The scaling from 1080p to 1440p on Ultra (104 FPS to 71 FPS, a 31.7% drop) is less severe than the subsequent 1440p to 4K drop (71 FPS to 42 FPS, a 40.8% drop), reinforcing that the GPU is the primary constraint at the highest resolution.

Settings Recommendations

Based on the measured data, the optimal experience for this hardware configuration depends heavily on the target resolution and desired frame rate. For gamers with 1080p displays, the High preset at 136 FPS is the sweet spot, offering a significant visual upgrade over Low (203 FPS) and Medium (161 FPS) while maintaining a frame rate that is more than sufficient for competitive play. The Ultra preset at 104 FPS is also viable for those who prioritize visual fidelity over a slight reduction in smoothness, as it remains above the 100 FPS threshold. However, the data shows that the performance gap between High and Ultra is 32 FPS, which is a substantial cost for the incremental visual gains that the Ultra preset provides.

For 1440p users, the High preset at 94 FPS is the recommended choice, as it delivers a smooth, responsive experience that is well-suited for fast-paced gameplay. The Medium preset at 111 FPS offers a higher frame rate but sacrifices visual quality, while the Ultra preset at 71 FPS is playable but may not be ideal for those who are sensitive to frame rate fluctuations. The 4K resolution is the most demanding scenario, and the data suggests that Medium settings at 66 FPS (min 56 FPS) are the maximum playable configuration, as the High preset at 55 FPS and Ultra preset at 42 FPS will likely result in noticeable stuttering and input lag during intense moments.

The minimum FPS values provided for the Medium presets offer additional insight into frame pacing. At 1080p Medium, the minimum of 137 FPS is still very high, indicating consistent performance. At 1440p Medium, the minimum of 94 FPS is still above the 60 FPS threshold, but the 4K Medium minimum of 56 FPS reveals that there are moments when the frame rate dips below 60 FPS, which could be problematic for some players. Given these measurements, the best experience per the data is to target 1080p High or 1440p High, as these presets provide a balance between visual quality and performance that is unmatched by the other options in the measured set.

CPU Role

The Intel Core i5-12400 is a six-core, 12-thread processor based on the Alder Lake architecture, with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. Its benchmark scores indicate strong single-threaded performance, with a 3dmark_single_thread score of 910 and a passmark_single_thread score of 3456. This single-thread performance is crucial for Rust, which is known for its heavy reliance on the main game thread for physics and entity updates. The processor’s 18 MB of shared L3 cache is also beneficial, as it allows for faster access to frequently used data across the cores.

The CPU’s multi-threaded capabilities are equally important, as the 3dmark_max_threads score of 5890 and cinebench_r23_multicore score of 15989 demonstrate. While Rust does not scale perfectly across all cores, the 12 threads allow the game to offload background tasks such as world generation and server communication, preventing these from creating bottlenecks on the main thread. The data shows that at 1080p Low settings, the system achieves 203 FPS, which is a clear indication that the CPU is not a limiting factor at this resolution and settings combination. The performance drop to 165 FPS at 1440p Low and 98 FPS at 4K Low is primarily driven by the GPU, as the CPU’s workload is largely resolution-independent.

The i5-12400’s percentile ranking of 72 against all CPUs places it in the upper tier of processors, and its nearest rivals in the benchmark database include the AMD EPYC 7643 (0.1% slower), Intel Core i7-1355U (0.3% slower), and AMD Ryzen AI 5 330 (0.7% slower). The Intel Core i3-14100F is 0.9% faster, which shows that the i5-12400 is competitive with modern mid-range options. In the context of Rust, the data suggests that the i5-12400 provides more than enough headroom for the RTX 5070, as the frame rate at 1080p High (136 FPS) is still significantly higher than the 4K High result (55 FPS), indicating that the GPU is the primary bottleneck in most scenarios. However, at 1080p Low (203 FPS), the system is likely approaching the CPU’s maximum frame generation capability, and further increases in GPU power would not yield proportionate gains.

GPU Role

The NVIDIA GeForce RTX 5070 is the clear performance driver in this pairing, and its specifications explain the measured results. The GPU is based on the Blackwell 2.0 architecture and features 6144 shading units, 192 texture mapping units, and 80 raster output units. Its boost clock of 2512 MHz and base clock of 2325 MHz provide the raw compute throughput, which is quantified by the FP32 performance of 30.87 TFLOPS. The 12 GB of GDDR7 memory on a 192-bit bus delivers a bandwidth of 672.0 GB/s, which is critical for feeding the massive amounts of texture data required at 4K resolution.

The GPU’s benchmark scores are robust, with a passmark_g3d score of 29137 and a geekbench_vulkan score of 178923. These scores place the RTX 5070 in the 82nd percentile of all GPUs, and its nearest rivals include the AMD Radeon Pro 580 (0.1% slower) and AMD Radeon Pro WX 7100 (0.8% slower). The data clearly shows that the GPU is the primary bottleneck at 4K resolution, as the average frame rates at 4K High (55 FPS) and 4K Ultra (42 FPS) are significantly lower than the 1080p results. This is consistent with the GPU’s memory bandwidth of 672.0 GB/s, which, while substantial, is not sufficient to maintain high frame rates when rendering Rust’s complex environments at 3840x2160.

The RTX 5070’s 80 ROPs and 201.0 GPixel/s pixel rate are responsible for the final output stage of the rendering pipeline, and these figures are adequate for 1080p and 1440p gaming. However, the 4K resolution requires nearly four times the pixel throughput of 1080p, which explains the dramatic performance drop. The GPU’s 192 tensor cores and 48 RT cores are also relevant, as Rust can leverage these for certain visual effects, though the measured data does not isolate their impact. Overall, the RTX 5070 is a capable GPU for Rust at 1080p and 1440p, but the data indicates that 4K gaming requires a significant reduction in settings to achieve playable frame rates. The 4K Medium preset, which averages 66 FPS, represents the practical limit for this GPU at this resolution.
