Rust

Rust is a demanding survival title that stresses both processor and graphics hardware, and the combination of the Intel Core i3-12100F with the AMD Radeon RX 7700 produces a distinctive performance profile across resolutions and settings. The data shows a system that is capable of high frame rates at 1080p, but which becomes increasingly GPU-limited as resolution scales up, with the CPU’s four physical cores proving sufficient for the game’s core logic while the GPU’s large memory pool and bandwidth handle the visual load.

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core i3-12100F is a 4-core, 8-thread processor based on the Alder Lake architecture, built on Intel’s 10 nm process. Its base clock is 3.30 GHz with a boost clock of 4.30 GHz, and it carries a 12 MB shared L3 cache. This CPU is positioned in the 68th percentile of all processors in the database, with an average benchmark score of 13494, placing it near rivals like the Intel Core i3 N355 (0% delta), Intel Core i5-9500 (0.3% faster), and Intel Core 5 120UL (0.7% slower). For Rust, the single-thread performance is critical, and the i3-12100F delivers strong results there, with a 3dmark single-thread score of 893 and a Cinebench R23 single-core score of 1674.

The multi-threaded capability of this chip is less imposing but still relevant. It scores 4051 in 3dmark 16-thread and 4026 in 8-thread tests, while Cinebench R23 multi-core reaches 11860. The 4-core design shows its limits in heavily threaded workloads, as evidenced by the PassMark multi-thread score of 14015, but Rust does not scale perfectly across many cores. The game’s simulation and entity processing tend to favor higher clock speeds and efficient single-core execution, which this processor provides. The 8 threads help with background tasks and the game’s server-side logic, but the primary contribution is the boost clock reaching 4.30 GHz to keep the main game thread fed.

The CPU’s memory support for both DDR4 and DDR5 gives flexibility, though the dual-channel bus width is standard. In Rust’s measured FPS, the CPU’s role is most evident at 1080p with Low settings, where the system achieves 173 FPS average. This high frame rate suggests the processor is not the bottleneck in that scenario, as the GPU is still able to push well beyond typical display refresh rates. However, at 4K Ultra, the frame rate drops to 30 FPS, indicating that the GPU has taken over as the primary constraint. The i3-12100F’s 4 cores are sufficient to avoid major stutters or frame-time spikes, but the data does not show this CPU as a performance leader in absolute terms; its percentile ranking of 68 means a substantial portion of CPUs tested will outperform it in synthetic benchmarks, yet in Rust, the practical impact is moderated by the game’s specific engine demands.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 7700 is a RDNA 3.0 architecture GPU built on TSMC’s 5 nm process, with a chip codenamed Wheat Nas. It features 16 GB of GDDR6 memory on a 256-bit bus, delivering a bandwidth of 624.1 GB/s. The memory clock runs at 2438 MHz (19.5 Gbps effective), while the base clock is 1900 MHz and the boost clock reaches 2459 MHz, with a game clock of 2041 MHz. This GPU sits in the 58th percentile of all GPUs, with an average benchmark score of 15852, placing it near the AMD Radeon R9 370X (0.1% faster), AMD Radeon RX 9060 (1% faster), and NVIDIA GeForce RTX 3060 Ti (1.7% faster). The 16 GB VRAM is a significant asset for Rust, which can consume large amounts of memory for textures and world data, especially at higher resolutions.

The GPU’s compute capabilities include 2560 shading units, 160 TMUs, and 96 ROPs, with a peak FP32 throughput of 25.18 TFLOPS. The pixel rate of 236.1 GPixel/s and texture rate of 393.4 GTexel/s indicate strong fill-rate performance. In Rust, the GPU’s role becomes dominant at higher resolutions. The data shows a clear progression: at 1080p Low, the GPU achieves 173 FPS, but this drops to 98 FPS at 1080p High. At 1440p, the Low setting yields 119 FPS, and at 4K, even Low settings only reach 70 FPS. The VRAM capacity ensures that texture loading does not cause hitches, but the raw compute power of the RX 7700 is what limits frame rates at 4K Ultra, where the system only averages 30 FPS. The GPU’s DirectX 12 Ultimate support and 40 RT cores are present, but Rust does not heavily utilize ray tracing, so the traditional rasterization performance, as measured by the PassMark G3D score of 20974, is more relevant.

The 200 W TDP and dual-slot design are typical for this class, and the PCIe 4.0 x16 interface provides adequate bandwidth. The GPU’s nearest rivals in terms of average score are all within 1.7% of each other, indicating that the RX 7700 is a mid-pack performer. In Rust, the measured FPS at 4K Medium shows a minimum of 40 FPS and maximum of 54 FPS, with an average of 47 FPS, which suggests that the GPU is working hard but not entirely overwhelmed. The 16 GB memory buffer is particularly beneficial for Rust’s large maps, preventing the need for constant asset streaming from system memory, but the GPU’s compute throughput is the deciding factor in high-resolution performance.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the Intel Core i3-12100F and AMD Radeon RX 7700 ranks 1295 out of 2953 tested combos in Rust. This places it in the 44th percentile of all CPU-GPU pairings tested for this game, meaning it outperforms more than half of the tested configurations but falls short of the top tier. The rank of 1295 indicates that while this combo is capable of playable frame rates at most settings, it is not among the elite pairings that can max out Rust at 4K. The data suggests a balanced pairing, where neither component is drastically holding back the other, but the overall performance ceiling is determined by the GPU’s mid-range positioning.

When considering the CPU’s 68th percentile and the GPU’s 58th percentile, the combo rank of 1295 out of 2953 is slightly lower than what the individual scores might imply. This could be due to Rust’s specific optimization, where the CPU’s 4 cores become a minor limiting factor in certain scenarios, or where the GPU’s performance at high resolutions does not scale as well as expected. The combo rank shows that there are 1294 other configurations that deliver better Rust performance, which is a substantial number, but also that there are 1658 combos that perform worse. This places the i3-12100F + RX 7700 in the middle of the pack, making it a reasonable choice for 1080p and 1440p gaming, but not for enthusiasts seeking maximum frame rates at 4K.

The rank also implies that users with higher-end CPUs paired with similar GPUs may see better results, as the CPU can sometimes be the bottleneck at lower resolutions. Conversely, pairing this CPU with a stronger GPU would likely yield diminishing returns, as the i3-12100F’s multi-threaded limits could cap performance. The data indicates that this combo is well-suited for its intended market segment, delivering solid performance in Rust without extreme sacrifices, but it does not threaten the top-ranked configurations.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data provides a comprehensive view of how this combo performs across different resolutions and quality settings. At 1920x1080, the system achieves 173 FPS on Low settings, which is the highest frame rate recorded for this combo. Moving to Medium settings at 1080p, the average drops to 116 FPS, with a minimum of 99 and maximum of 133 FPS. High settings at 1080p yield 98 FPS average, and Ultra settings produce 75 FPS. This progression shows a smooth scaling from Low to Ultra, with a total drop of 98 FPS between the lowest and highest settings at 1080p.

At 2560x1440, the performance degrades as expected. Low settings average 119 FPS, which is still very playable. Medium settings drop to 80 FPS, with a minimum of 68 and maximum of 92 FPS. High settings average 67 FPS, and Ultra settings fall to 51 FPS. The difference between Low and Ultra at 1440p is 68 FPS, indicating that the GPU is becoming more of a limiting factor as resolution increases. At 3840x2160, the frame rates drop significantly. Low settings average 70 FPS, Medium settings average 47 FPS with a minimum of 40 and maximum of 54, High settings average 40 FPS, and Ultra settings only reach 30 FPS. The gap between Low and Ultra at 4K is 40 FPS, which is the smallest absolute difference across resolutions, but the percentage drop is steep.

The data shows that for 1080p gaming, this combo can handle all settings with average frame rates above 75 FPS, which is smooth for most players. At 1440p, the combo is still viable, with Ultra settings staying above 50 FPS. However, at 4K, only Low settings provide a comfortably playable experience above 60 FPS, while Ultra settings dip to 30 FPS, which may be acceptable for some but is not ideal for fast-paced action. The minimum FPS values, where available, show that the Medium settings at all resolutions maintain a playable floor, with 99 FPS at 1080p, 68 FPS at 1440p, and 40 FPS at 4K.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The scaling from 1080p to 4K reveals the nature of the bottleneck in this combo. At Low settings, the frame rate drops from 173 FPS at 1080p to 119 FPS at 1440p (a 31% reduction) and then to 70 FPS at 4K (a 41% reduction from 1440p). This steep decline indicates that the GPU is heavily stressed at higher resolutions, as the CPU has enough headroom at 1080p Low to allow the GPU to run at its maximum potential. The fact that 173 FPS is achievable at 1080p Low suggests that the i3-12100F is not a limiting factor at that setting, as the GPU is still able to produce a high frame rate.

At Ultra settings, the scaling is less severe in absolute terms but still shows GPU dominance. The frame rate drops from 75 FPS at 1080p to 51 FPS at 1440p (a 32% reduction) and then to 30 FPS at 4K (a 41% reduction from 1440p). The consistent percentage drops across settings indicate that the GPU is the primary limiting component in all scenarios, as the CPU’s workload does not increase significantly with resolution. This is typical for a game like Rust, where the CPU handles game logic and the GPU renders the scene, and increasing resolution only adds pixels for the GPU to process.

The data also shows that the gap between Low and Ultra settings widens as resolution decreases. At 1080p, the difference between Low and Ultra is 98 FPS, while at 4K, it is only 40 FPS. This is because at lower resolutions, the CPU can feed the GPU more frames, and the GPU’s faster rendering at Low settings is more apparent. At 4K, both Low and Ultra settings are limited by the GPU’s pixel throughput, so the difference narrows. This pattern confirms that the AMD Radeon RX 7700 is the bottleneck at 4K, while the Intel Core i3-12100F is sufficient to keep up at lower resolutions. The CPU’s 4 cores do not appear to cause a significant frame rate cap, as the 173 FPS at 1080p Low demonstrates headroom, but the GPU’s 25.18 TFLOPS of compute is simply not enough to maintain high frame rates at 4K Ultra.
