Rust

The Intel Core i5-12400F paired with the AMD Radeon RX 7600 delivers a playable but constrained experience in Rust, with the data showing a clear transition from CPU-bound behavior at lower resolutions to GPU-bound behavior at 4K. The measured frames per second (FPS) reveal a system that is well-balanced for 1080p gaming but struggles to maintain high refresh rates as pixel count increases.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent across all settings presets, indicating that the Radeon RX 7600 becomes the primary limiting factor at higher resolutions. At Low settings, the average frame rate falls from 138 FPS at 1920x1080 to 95 FPS at 2560x1440, a reduction of 43 FPS, and then drops further to 56 FPS at 3840x2160. This represents a 59.4% decrease in performance from 1080p to 4K, a substantial hit that points directly at the GPU’s rendering capabilities.

The scaling pattern at Medium settings mirrors this trend: 93 FPS at 1080p, 64 FPS at 1440p, and 38 FPS at 4K. The gap between 1080p and 1440p is 29 FPS, while the gap between 1440p and 4K is 26 FPS, showing a nearly linear decline as resolution increases. High settings follow a similar trajectory, with 78 FPS at 1080p, 54 FPS at 1440p, and 32 FPS at 4K. The 4K High result of 32 FPS is barely above the 30 FPS threshold, making it marginal for smooth gameplay.

Ultra settings tell the most telling story about the GPU bottleneck. The RX 7600 manages 60 FPS at 1080p Ultra, but this collapses to 41 FPS at 1440p and a meager 24 FPS at 4K. The 24 FPS figure at 4K Ultra is the lowest recorded in the entire dataset, and the fact that it falls below 30 FPS suggests the GPU is completely saturated at this configuration. The data indicates that the 4K resolution is simply too demanding for this card in Rust, regardless of the quality preset chosen.

The FPS scaling between 1080p and 1440p is more moderate, with an average reduction of roughly 30-35% across settings. This is typical for a mid-range GPU, as the pixel count increases by 78% when moving from 1920x1080 to 2560x1440, but the frame rate does not drop proportionally, suggesting some headroom in the GPU’s compute units. However, the jump to 4K quadruples the pixel count, and the RX 7600’s 8 GB frame buffer and 128-bit memory interface become evident bottlenecks.

GPU Role

The AMD Radeon RX 7600 is built on the RDNA 3.0 architecture with a Navi 33 chip, featuring 2048 shading units, 128 texture mapping units, and 64 raster operations pipelines. It operates at a base clock of 1720 MHz and a boost clock of 2655 MHz, with a game clock rated at 2250 MHz. The memory configuration consists of 8 GB of GDDR6 on a 128-bit bus, delivering 288.0 GB/s of bandwidth. These specifications are modest by modern standards, and the benchmark results in Rust reflect this.

The GPU’s PassMark G3D score of 16634 places it in the 57th percentile of all GPUs, indicating it is slightly above average but far from top-tier. Its nearest rival, the NVIDIA GeForce RTX 3050 OEM, scores 15199, a 0.2% difference, while the AMD Radeon 680M scores 15270, 0.7% higher. This puts the RX 7600 in a competitive but not dominant position among its peers, and Rust’s demanding rendering engine exposes its limitations at higher resolutions.

At 1080p, the GPU has enough bandwidth and compute power to push frame rates well above 60 FPS on Low and Medium settings, with 138 FPS and 93 FPS respectively. This suggests the GPU is not the primary bottleneck at this resolution, as the processor can feed it enough data to keep it busy. The Ultra preset at 1080p yields 60 FPS, which is exactly the threshold for smooth gameplay, indicating that the GPU is starting to reach its limits with maximum quality settings.

The 4K results, however, show the GPU’s weaknesses clearly. With only 8 GB of VRAM and 288.0 GB/s of bandwidth, the card struggles to manage the texture and geometry data required at 3840x2160. The drop to 24 FPS at Ultra settings is a clear sign of memory bandwidth saturation, as the GPU cannot fetch data fast enough to maintain a playable frame rate. Even at Low settings, 4K only produces 56 FPS, which is playable but not smooth for fast-paced survival gameplay.

CPU Role

The Intel Core i5-12400F is a 6-core, 12-thread processor based on Alder Lake architecture, with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. It has 18 MB of shared L3 cache and supports both DDR4 and DDR5 memory, though the benchmark results suggest it is more than capable of keeping up with the RX 7600 in Rust. The processor’s PassMark multithread score of 19433 and single-thread score of 3481 indicate solid performance for a mid-range desktop chip.

The CPU’s Cinebench R23 multicore score of 12380 and single-core score of 1680 show that it handles both multi-threaded and single-threaded workloads effectively. Rust is known for being CPU-intensive due to its large persistent world and complex physics simulation, but the 12400F’s 6 cores and 12 threads provide adequate compute throughput. The 3DMark 16-thread score of 5895 and 2-thread score of 1699 demonstrate that the processor scales reasonably well across different thread counts.

The data suggests that at 1080p, the CPU is the limiting factor. The jump from 138 FPS on Low to 93 FPS on Medium is 45 FPS, but the difference between Medium and High is only 15 FPS, and High to Ultra is 18 FPS. This non-linear scaling indicates that the CPU is reaching its maximum frame delivery capability around 138 FPS, and the GPU is not fully utilized until higher resolutions. At 1440p, the frame rates drop to 95 FPS on Low and 54 FPS on High, showing that the GPU is taking over as the bottleneck as pixel count increases.

The CPU’s performance relative to its rivals is noteworthy. Its average benchmark score of 19039 is nearly identical to the AMD Ryzen 5 7535HS at 19047, with a 0% delta, and the Intel Core 3 201E at 19056, with a -0.1% delta. This places the 12400F in a tightly contested group, but its 73rd percentile ranking among all CPUs confirms it is a capable processor for gaming. In Rust specifically, the 12400F provides enough single-thread performance to avoid severe frame drops, as evidenced by the 138 FPS result at 1080p Low.

How This Combo Ranks

The combination of the Intel Core i5-12400F and AMD Radeon RX 7600 ranks 2596 out of 3723 tested combos in Rust, placing it in the 30th percentile of all configurations. This rank reflects the GPU’s mid-range positioning, as the CPU is not the primary constraint in most scenarios. The data shows that this combo is better suited for 1080p gaming, where it can achieve high frame rates, but falls behind more powerful systems at higher resolutions.

The GPU’s 57th percentile ranking among all GPUs is notably lower than the CPU’s 73rd percentile, indicating that the graphics card is the weaker component in this pairing. This imbalance becomes apparent in Rust, where the game’s rendering demands push the GPU to its limits. At 1080p Ultra, the combo achieves 60 FPS, which is respectable, but the 4K Ultra result of 24 FPS is among the lowest in the dataset, dragging down the overall rank.

Compared to other combos, this system performs best at 1080p where the CPU’s strong single-thread performance can shine. The 138 FPS result at Low settings is competitive, and the 78 FPS at High settings provides a smooth experience for most players. However, the rank indicates that many other combos deliver higher frame rates, particularly those with more powerful GPUs that can handle Rust’s demanding graphics at higher resolutions.

The ranking also suggests that this combo is not ideal for 1440p or 4K gaming. At 1440p High, the 54 FPS average is playable but requires turning down settings to achieve higher frame rates. The 4K results are marginal at best, with only the Low preset exceeding 50 FPS. For players targeting higher resolutions, the data indicates that a more powerful GPU would be necessary to improve the combo’s ranking.
