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

The Intel Core i5-12600KF is a 10-core, 16-thread processor based on the Alder Lake architecture, built on Intel's 10 nm process. It runs at a base clock of 3.70 GHz and boosts up to 4.90 GHz, with a 125 W TDP. The chip uses a dual-channel memory interface supporting both DDR4 and DDR5, and its 20 MB of shared L3 cache is a key resource for a game like Rust, which is known for heavy entity and world-state simulation.

Benchmark data shows this CPU sits at the 84th percentile among all tested processors, with an average benchmark score of 27827. Its closest rival is the Intel Core i9-10900K, which scores 27829 — a 0% deltaPct. The Core i5-12600K scores 27851 (-0.1% deltaPct), while the Intel Core Ultra 5 125H scores 27872 (-0.2% deltaPct). The Intel Core i7-13700H scores 27716 (+0.4% deltaPct). In practical terms, this means the 12600KF is statistically indistinguishable from the i9-10900K in aggregate CPU performance, and it trades blows with laptop-class parts that often have different power envelopes.

In Rust specifically, the CPU's single-threaded strength matters. The chip scores 3309 in Cinebench R23 single-core and 3925 in Passmark single-thread. These figures are important because Rust's simulation loop — building physics, AI, and network updates — tends to scale with strong single-core performance. The 12600KF's boost clock of 4.90 GHz gives it headroom in these scenarios. The multi-threaded scores tell a similar story: Cinebench R23 multicore is 23444, and Passmark multithread is 27575. With 10 cores and 16 threads, the CPU can handle background tasks and the game's server-side processing without becoming the primary bottleneck at lower resolutions.

When looking at the measured FPS data, the CPU's influence is most visible at 1080p Low settings, where the combo hits 226.4 FPS. At that setting, the GPU is not the limiting factor; instead, the CPU's ability to feed frames quickly dictates the ceiling. The jump from 1080p Low to 1440p Low (152.7 FPS) and then to 4K Low (90.7 FPS) shows the CPU's headroom diminishing as resolution increases.

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

The NVIDIA GeForce RTX 4070 uses the AD104 chip on TSMC's 5 nm process, with 35,800 million transistors packed into a 294 mm² die. It has 5888 shading units, 184 texture mapping units, and 64 ROPs, plus 46 ray tracing cores and 184 tensor cores. The GPU's base clock is 1920 MHz, boosting to 2475 MHz. Memory consists of 12 GB of GDDR6X on a 192-bit bus, delivering 504.2 GB/s of bandwidth.

The RTX 4070 sits at the 81st percentile among all tested GPUs, with an average benchmark score of 37283. Its nearest rivals show a mixed bag: the AMD Radeon RX Vega 56 scores 37507 (-0.6% deltaPct), the NVIDIA GeForce MX570 A scores 38008 (-1.9% deltaPct), and the NVIDIA GeForce RTX 4080 Mobile scores 38135 (-2.2% deltaPct). The AMD Radeon RX 5300M scores 36371 (+2.5% deltaPct). These deltas indicate the RTX 4070 is clustered tightly with these parts in synthetic benchmarks, though real-world gaming performance can diverge significantly.

For Rust, the 12 GB VRAM capacity is a major advantage. The game's asset streaming — especially with high-resolution textures and large bases — can consume several gigabytes. At 4K Ultra settings, the measured average FPS drops to 38.3, which suggests the GPU is being pushed hard. The 504.2 GB/s memory bandwidth becomes critical at higher resolutions, as the GPU must move more texture data per frame. The pixel rate of 158.4 GPixel/s and texture rate of 455.4 GTexel/s provide the raw throughput needed for Rust's draw calls, but the Ultra preset's effects (ambient occlusion, shadows, and post-processing) tax the shader units heavily.

The GPU's FP32 compute of 29.15 TFLOPS is the same as its FP16 figure (1:1), which indicates a balanced design for both rasterization and compute workloads. In Rust, this translates to consistent frame pacing across different scenes — from open fields to dense forested areas with many dynamic objects.

# Settings Recommendations — which preset gives the best experience per the measured rows

The measured data provides clear guidance. At 1080p, the Low preset delivers 226.4 FPS, Medium delivers 152.6 FPS, High delivers 125.7 FPS, and Ultra delivers 99 FPS. The step from Low to Medium costs 73.8 FPS (a 32.6% drop), while Medium to High costs 26.9 FPS, and High to Ultra costs 26.7 FPS. The largest relative jump is from Low to Medium, which suggests that the Low preset may be leaving performance on the table that Medium can reclaim without excessive cost.

At 1440p, the pattern shifts. Low delivers 152.7 FPS, Medium 104.7 FPS, High 87.7 FPS, and Ultra 68.2 FPS. The delta between Low and Medium is 48 FPS (31.4% drop), Medium to High is 17 FPS, and High to Ultra is 19.5 FPS. At 4K, Low gives 90.7 FPS, Medium 64 FPS, High 52.8 FPS, and Ultra 38.3 FPS. The drop from High to Ultra at 4K is 14.5 FPS — a 27.5% reduction — making Ultra arguably not worth the visual gain for most players.

The best experience per the measured rows depends on the target. For high-refresh 1080p monitors, High at 125.7 FPS offers a strong balance of visual quality and smoothness, staying above the 120 FPS threshold. For 1440p, Medium at 104.7 FPS is the sweet spot, as it remains above 100 FPS while providing better visuals than Low. For 4K, Low at 90.7 FPS is the only preset that stays comfortably above 60 FPS; Medium at 64 FPS is borderline, and High at 52.8 FPS falls short of the 60 FPS mark.

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

The FPS scaling across resolutions reveals the bottleneck shifting from CPU to GPU. At Low settings, the combo delivers 226.4 FPS at 1080p, 152.7 FPS at 1440p, and 90.7 FPS at 4K. The drop from 1080p to 1440p is 73.7 FPS (32.6% reduction), and from 1440p to 4K is 62 FPS (40.6% reduction). The almost linear scaling suggests that at Low settings, the GPU is still doing meaningful work, but the CPU's frame generation capability is close to the ceiling at 1080p.

At Medium settings, the numbers are 152.6 FPS (1080p), 104.7 FPS (1440p), and 64 FPS (4K). The drop from 1080p to 1440p is 47.9 FPS (31.4%), and from 1440p to 4K is 40.7 FPS (38.9%). The scaling is more gradual, indicating that the GPU's fill rate and memory bandwidth are becoming more significant factors.

At High settings, the FPS goes from 125.7 (1080p) to 87.7 (1440p) to 52.8 (4K). The 1080p-to-1440p drop is 38 FPS (30.2%), and the 1440p-to-4K drop is 34.9 FPS (39.8%). Here, the GPU is clearly the limiting component — the 4K result falls below 60 FPS, and the CPU's headroom is no longer the constraint.

Ultra settings show the most dramatic scaling: 99 FPS at 1080p, 68.2 FPS at 1440p, and 38.3 FPS at 4K. The 1080p-to-1440p drop is 30.8 FPS (31.1%), and the 1440p-to-4K drop is 29.9 FPS (43.8%). At Ultra, the RTX 4070's compute resources are saturated, and the 4K result is less than half of the 1080p result.

This pattern indicates that the i5-12600KF provides ample CPU performance for Rust across all settings — even at 1080p Low, the 226.4 FPS figure shows the CPU is not the primary limit. The GPU becomes the bottleneck as resolution and settings increase, with the 12 GB VRAM and 504.2 GB/s bandwidth being insufficient to maintain high FPS at 4K Ultra.

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

The measured FPS data is organized by resolution and preset. At 1920x1080, the combo achieves the following average FPS: Low 226.4, Medium 152.6, High 125.7, Ultra 99. At 2560x1440: Low 152.7, Medium 104.7, High 87.7, Ultra 68.2. At 3840x2160: Low 90.7, Medium 64, High 52.8, Ultra 38.3.

The 1080p results show that the combo can drive high-refresh monitors at all presets. Even Ultra at 99 FPS stays above the 90 FPS mark, which is playable for most competitive scenarios. The 1440p results are more mixed: Low and Medium exceed 100 FPS, High stays above 85 FPS, but Ultra dips to 68.2 FPS. At 4K, only Low and Medium exceed 60 FPS, with High and Ultra falling below that threshold.

The percentage drop from one preset to the next is consistent across resolutions. At 1080p, Low-to-Medium is a 32.6% reduction, Medium-to-High is 17.6%, and High-to-Ultra is 21.2%. At 1440p, Low-to-Medium is 31.4%, Medium-to-High is 16.2%, and High-to-Ultra is 22.2%. At 4K, Low-to-Medium is 29.4%, Medium-to-High is 17.5%, and High-to-Ultra is 27.5%. The consistency suggests that the settings presets scale similarly regardless of resolution, with the GPU's overall load increasing uniformly.
