Rust

The Intel Core i5-12400F paired with the AMD Radeon RX 9070 XT delivers a robust 1080p experience in Rust, but the data reveals a dramatic shift in performance characteristics as resolution climbs. At 1920x1080 with Low settings, the combo produces an average of 204.8 FPS, which drops to 128.4 FPS at High and 97.5 FPS at Ultra. This scaling pattern—a 52.4% reduction from Low to Ultra at 1080p—indicates that even at this resolution, the graphics card is already bearing significant load, though the CPU remains capable of feeding it adequately.

Moving to 2560x1440, the frame rates remain strong but show the expected decline: 153 FPS at Low, 106.5 FPS at Medium, 87.3 FPS at High, and 66.5 FPS at Ultra. The gap between Low and Ultra at 1440p narrows to 56.5%, suggesting the GPU is becoming the primary constraint as pixel count increases. At 3840x2160, the picture changes decisively. The RX 9070 XT manages 91.3 FPS at Low, 61.9 FPS at Medium, 50.4 FPS at High, and 42.2 FPS at Ultra. The 54.0% drop from Low to Ultra at 4K is the steepest of all resolutions tested, confirming that the GPU is now the definitive bottleneck.

The resolution scaling data tells a clear story about component balance. At 1080p Low, the system achieves over 200 FPS, which is far beyond what most displays can refresh, indicating the CPU is not limiting performance in that scenario. However, the fact that 1080p Ultra still yields 97.5 FPS—only 17.4% lower than the 1440p High result of 87.3 FPS—suggests that the i5-12400F's six cores can keep pace with the GPU's output across most settings. The real takeaway is that this combo is well-matched for 1440p gaming, where it maintains 66.5 FPS at Ultra, while 4K Ultra at 42.2 FPS falls below the 60 FPS threshold that many players consider the minimum for smooth play.

CPU Role

The Core i5-12400F is a 6-core, 12-thread processor based on the Alder Lake architecture, manufactured on Intel's 10 nm process. Its base clock of 2.50 GHz and boost clock of 4.40 GHz provide the computational foundation for Rust's simulation-heavy gameplay, which includes complex physics, building destruction, and large player populations. The CPU's 18 MB of shared L3 cache and 1.25 MB L2 cache per core help reduce memory latency, which is critical for a game that frequently streams terrain and entity data.

In synthetic benchmarks, the i5-12400F achieves a single-thread score of 909 in 3DMark and 2332 in Cinebench R23, placing it in the 77th percentile of all CPUs tested. Its multi-threaded performance is equally notable: 5912 in 3DMark max threads, 16518 in Cinebench R23 multicore, and 9138 in Geekbench multicore. These figures translate to an average benchmark score of 19221, which places it within 0.1% of the Intel Core i7-8700K (19210) and 0.3% ahead of the Intel Core i5-1335U (19167). The data shows the 12400F is positioned slightly above the AMD Ryzen 5 7533HS (19364, -0.7%) and the AMD EPYC 7773X (18979, 1.3%).

For Rust specifically, the CPU's role becomes more pronounced at lower resolutions where the GPU is not saturated. At 1080p Low, the 204.8 FPS result demonstrates that the 12400F can drive frame rates well above 200 FPS when the graphics load is minimal. However, the performance drop to 97.5 FPS at 1080p Ultra—a 52.4% decrease—suggests that while the CPU provides sufficient headroom, the GPU's workload scaling dominates the frame rate equation. The 12400F's 4.40 GHz boost clock and 6 physical cores appear adequate for Rust's single-threaded physics and AI tasks, as evidenced by the strong 128.4 FPS at 1080p High, which is only 16.8% below the 1440p Low result of 153 FPS.

GPU Role

The AMD Radeon RX 9070 XT is the dominant component in this pairing, featuring 16 GB of GDDR6 memory on a 256-bit bus with 644.6 GB/s of bandwidth. The GPU is built on the RDNA 4.0 architecture using TSMC's 4 nm process, with 4096 shading units, 256 TMUs, and 128 ROPs. Its boost clock reaches 2970 MHz, with a game clock of 2400 MHz, delivering 48.66 TFLOPS of FP32 performance. The 16 GB VRAM capacity is particularly relevant for Rust, which can consume significant memory when rendering large bases and dense vegetation at high resolutions.

In raw compute terms, the RX 9070 XT posts a 3DMark Steel Nomad score of 7260 and a Geekbench Vulkan score of 184026, placing it in the 82nd percentile of all GPUs. Its average benchmark score of 39647 is nearly identical to the AMD Radeon Pro 575 (39703, -0.1%) and the NVIDIA RTX A500 Mobile (39568, 0.2%), though it trails the AMD Radeon Pro 575X (39836, -0.5%) and AMD Radeon RX Vega 64 (39879, -0.6%) by a hair. These rival comparisons show that the RX 9070 XT sits in a crowded performance band, but its 16 GB frame buffer and modern architecture give it an edge in high-resolution gaming.

The GPU's impact on Rust performance is unmistakable in the 4K results. At 3840x2160, the RX 9070 XT delivers 91.3 FPS at Low, but this falls to 50.4 FPS at High and 42.2 FPS at Ultra. The 42.2 FPS at 4K Ultra represents a 79.4% drop from the 204.8 FPS at 1080p Low, underscoring how heavily the GPU is taxed by Rust's detailed textures and lighting at higher resolutions. The 16 GB VRAM buffer helps prevent texture thrashing, as evidenced by the smooth scaling from Medium (61.9 FPS) to High (50.4 FPS) at 4K, which shows only an 18.6% performance penalty for the quality increase.
