Rust

Rust’s benchmark results for the Intel Core i5-12600KF paired with the AMD Radeon RX 7600 show a configuration that scales predictably with resolution, though the frame rate drop from 1080p to 4K is steep enough to expose the GPU as the primary bottleneck at higher settings. At 1920x1080 with Low settings, the combo delivers 140.4 FPS, which falls to 96.5 FPS at 2560x1440 and further to 59.4 FPS at 3840x2160. This represents a 57.7% reduction in frame rate from 1080p to 4K at Low settings, a scaling pattern that indicates the Radeon RX 7600’s 8 GB VRAM and 128-bit memory bus are under significant strain as pixel count rises. Moving to High settings, the frame rate drops from 77.6 FPS at 1080p to 56.1 FPS at 1440p, and then to 33.7 FPS at 4K — a 56.6% loss from 1080p to 4K, nearly identical to the Low setting scaling. This consistency across settings suggests that the limiting component is not the CPU’s thread management but rather the GPU’s raw throughput, which is taxed by Rust’s draw calls and texture streaming at higher resolutions.

The frame rate scaling between Medium and Ultra settings reinforces this interpretation. At 1080p, Medium yields 93.1 FPS, while Ultra drops to 57.6 FPS, a 38.1% decrease from Medium to Ultra. At 1440p, the same settings drop from 65.5 FPS to 43.3 FPS, a 33.9% decrease. At 4K, Medium produces 36.4 FPS and Ultra falls to 25.6 FPS, a 29.7% decrease. The diminishing percentage gap at higher resolutions is a classic sign that the GPU is becoming the sole constraint, as the CPU’s ability to feed frames becomes less relevant when the render target grows. The data shows that at 1080p Low, the CPU has headroom to push 140.4 FPS, but at 4K Ultra, the GPU is only able to muster 25.6 FPS, which is below the threshold for smooth gameplay in a survival title where quick reactions matter.

How This Combo Ranks

The combination of the Intel Core i5-12600KF and AMD Radeon RX 7600 ranks 1138 out of 1717 tested combos in Rust, placing it in the lower third of the database. This ranking is notable because the individual components perform above average in their respective categories — the CPU sits at the 84th percentile among all CPUs, and the GPU sits at the 63rd percentile among all GPUs. Yet the combo’s rank in Rust is disproportionately low, indicating that the game’s engine is particularly sensitive to the GPU’s memory bandwidth or the CPU’s cache architecture. The CPU’s nearest rivals include the Intel Core i9-10900K with an average score of 27829 (0% delta), the Intel Core i5-12600K at 27851 (-0.1% delta), and the Intel Core Ultra 5 125H at 27872 (-0.2% delta). These near-identical scores suggest that the i5-12600KF is well-matched to its peers in synthetic benchmarks, but the Rust combo rank reveals that real-world gaming performance does not always follow synthetic averages.

The GPU’s nearest rivals show a similar clustering: the AMD Radeon RX 7600 XT scores 20146 (0.6% higher), the AMD Radeon RX 460 scores 20088 (0.8% higher), while the NVIDIA GeForce RTX 3070 Mobile scores 20534 (-1.3% lower) and the Intel Arc B570 scores 20556 (-1.5% lower). The RX 7600’s average benchmark score of 20258 is nearly identical to these rivals, yet the combo rank in Rust suggests that the pairing with the i5-12600KF does not translate into a high placement. This discrepancy points to Rust’s specific demands, which may favor different hardware balances. With 1717 combos tested, a rank of 1138 means that roughly 66% of other configurations deliver better frame rates in this game, a sobering statistic for a CPU that ranks in the top 16% and a GPU in the top 37% of their respective fields.

GPU Role

The AMD Radeon RX 7600 is built on the RDNA 3.0 architecture with a Navi 33 chip, fabricated on a 6 nm process from TSMC. It carries 8 GB of GDDR6 memory on a 128-bit bus, yielding a bandwidth of 288.0 GB/s. The GPU’s base clock is 1720 MHz, with a boost clock of 2655 MHz and a game clock of 2250 MHz. These clocks are relatively high, but the 128-bit memory bus is narrow compared to other cards in its class, and the data shows that Rust’s frame rates at 4K are heavily constrained by this memory interface. At 4K Ultra, the GPU produces only 25.6 FPS, which is 55.5% lower than the 57.6 FPS at 1080p Ultra. The 8 GB VRAM capacity is sufficient for Rust’s textures at 1080p and 1440p, but at 4K, the engine’s asset streaming may exceed the memory buffer, causing the GPU to rely on slower fallback paths.

The GPU’s pixel rate is 169.9 GPixel/s and its texture rate is 339.8 GTexel/s, with FP32 compute at 21.75 TFLOPS. These figures suggest a card capable of moderate 1440p gaming, but the benchmark results show that Rust at 4K High (33.7 FPS) and 4K Medium (36.4 FPS) are both below the 60 FPS threshold. The GPU’s percentile rank of 63 means it outperforms 63% of all GPUs, yet in Rust, the measured FPS at 1440p Ultra (43.3 FPS) is barely playable. The Radeon RX 7600’s nearest rival, the RX 7600 XT, scores 0.6% higher in average benchmarks, but the data does not show how that translates to Rust specifically. The GPU’s launch MSRP is 269 USD, and it supports DirectX 12 Ultimate, Vulkan 1.4, and OpenGL 4.6, which are all relevant for Rust’s rendering pipeline.

Measured FPS Breakdown

At 1920x1080, the combo delivers 140.4 FPS on Low settings, 93.1 FPS on Medium, 77.6 FPS on High, and 57.6 FPS on Ultra. The gap between Low and Ultra is 82.8 FPS, a 59.0% reduction, which is a wide spread that indicates the GPU is the primary driver of performance differences at this resolution. At 2560x1440, the frame rates drop to 96.5 FPS on Low, 65.5 FPS on Medium, 56.1 FPS on High, and 43.3 FPS on Ultra. The transition from 1080p to 1440p at Low settings costs 43.9 FPS, a 31.2% reduction, while the same resolution change at Ultra costs 14.3 FPS, a 24.8% reduction. This asymmetric scaling suggests that at higher settings, the GPU is already saturated, so additional resolution has a smaller relative impact.

At 3840x2160, the frame rates are 59.4 FPS on Low, 36.4 FPS on Medium, 33.7 FPS on High, and 25.6 FPS on Ultra. The jump from 1440p to 4K at Low settings is a 37.1 FPS loss, a 38.4% reduction, which is significant but less severe than the 1080p-to-1440p drop at Low. However, at Ultra settings, the 4K frame rate of 25.6 FPS is only 59.1% of the 1440p Ultra frame rate of 43.3 FPS. The data shows that 4K Low (59.4 FPS) is the only 4K setting that approaches playability, while 4K Medium and High both hover in the low-to-mid 30s, and 4K Ultra falls below 30 FPS. For a survival game like Rust, where environmental detail and draw distance matter, these numbers indicate that the RX 7600 cannot handle 4K at medium or higher settings without significant compromises.

CPU Role

The Intel Core i5-12600KF is a 10-core, 16-thread processor from the Alder Lake architecture, with a base clock of 3.70 GHz and a boost clock of 4.90 GHz. Its cache hierarchy includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 20 MB of shared L3 cache. The CPU’s passmark multithread score is 27575, and its single-thread score is 3925, with a Cinebench R23 multicore score of 23444 and singlecore score of 3309. These numbers place the CPU in the 84th percentile of all CPUs, which is a strong showing for a mid-range desktop part. In Rust, the CPU’s role is primarily to manage the game’s physics and entity updates, which are often single-threaded or lightly threaded, and the data suggests that the i5-12600KF is not the limiting factor at 1080p Low, where 140.4 FPS is achieved.

The CPU’s nearest rivals include the Intel Core i9-10900K with an average score of 27829 (0% delta), which is a 10-core, 20-thread part, and the Intel Core i5-12600K with a score of 27851 (-0.1% delta). The fact that the i5-12600KF scores nearly identically to the i9-10900K in synthetic benchmarks suggests that its hybrid architecture with performance and efficiency cores is well-optimized for multithreaded workloads. However, the combo rank in Rust at 1138 out of 1717 indicates that the CPU’s strong synthetic performance does not boost the pairing to a top-tier position in this specific game. The CPU’s boost clock of 4.90 GHz is beneficial for Rust’s single-threaded logic, but the data shows that at 4K Ultra, the frame rate is 25.6 FPS, which is likely constrained by the GPU, not the CPU. At 1080p Low, the CPU has enough headroom to push 140.4 FPS, but the GPU’s limitations become apparent at higher resolutions and settings.
