Rust

The Intel Core i5-14600KF paired with the NVIDIA GeForce RTX 4070 delivers a compelling Rust experience, but the data reveals a clear bottleneck shift depending on resolution. At 1920x1080, the combination is heavily CPU-bound, with frame rates scaling dramatically with preset changes. The average FPS at Low settings hits 222.8, dropping to 150.9 at Medium, 127.2 at High, and 100 at Ultra. This steep decline as settings increase indicates that the GPU is being fed more work, but the sheer headroom at lower presets shows the processor is capable of pushing far beyond what the graphics card can render at higher loads. The 14-core, 20-thread i5-14600KF, with a boost clock of 5.30 GHz, provides ample single-thread performance for Rust's simulation-heavy world.

Moving to 2560x1440, the scaling pattern shifts noticeably. Low settings produce 158 FPS, Medium drops to 102.7, High to 88, and Ultra to 67.1. The percentage drop from Low to Ultra at 1440p is approximately 57.5%, which is less severe than the 55.1% drop seen at 1080p. This suggests that while the GPU is becoming more of a limiting factor, the CPU still holds significant sway at this resolution. The RTX 4070, with its 12 GB of GDDR6X memory and 504.2 GB/s bandwidth, is beginning to feel the pressure, but the i5-14600KF's high clock speeds keep the pipeline full. The 1440p results show a balanced system where neither component completely dominates, making it a sweet spot for competitive play with high refresh rate monitors.

At 4K (3840x2160), the tables turn decisively toward the GPU. The average FPS at Low is 90.6, but this plummets to 58.7 at Medium, 52 at High, and 41.4 at Ultra. The gap between Low and Ultra at 4K is a massive 54.3% reduction, but the absolute numbers tell the real story: the RTX 4070 is the clear limiter here. The transition from 1440p Low (158 FPS) to 4K Low (90.6 FPS) represents a 42.7% performance hit, which aligns with the pixel count increase of roughly 2.25x. This indicates that while the CPU still matters, the GPU's rasterization throughput is the primary constraint at 4K. The 5 nm Ada Lovelace architecture, with 5888 shading units and a boost clock of 2475 MHz, is working hard, but Rust's demanding draw calls and lighting models at 4K overwhelm it.

Resolution Scaling

The data shows a classic resolution scaling curve, but with an unusual twist: the CPU remains relevant even at 4K. From 1080p to 1440p at High settings, the average FPS drops from 127.2 to 88, a 30.8% reduction. At 1440p to 4K at High, the drop is from 88 to 52, a 40.9% reduction. This non-linear scaling indicates that while the GPU load increases with pixel count, the CPU's ability to maintain frame pacing becomes less critical as the GPU takes longer to render each frame. However, the 4K Low result of 90.6 FPS versus 1440p Low at 158 FPS shows a 42.7% drop, suggesting that even at the lowest settings, the RTX 4070's 192-bit memory bus and 158.4 GPixel/s pixel rate are the limiting factors.

The most telling comparison is the Low-to-Ultra scaling at each resolution. At 1080p, the difference between 222.8 and 100 FPS is 122.8 FPS, a massive spread that highlights the CPU's ability to feed frames rapidly when the GPU is underutilized. At 1440p, the spread narrows to 90.9 FPS (158 to 67.1), and at 4K, it narrows further to 49.2 FPS (90.6 to 41.4). This convergence at higher resolutions confirms that the GPU becomes the dominant bottleneck as resolution increases, but the i5-14600KF's performance ceiling is never fully exposed. The processor's 24 MB of shared L3 cache and dual-channel DDR5 memory support ensure that data delivery to the GPU remains consistent, even when the graphics card is struggling.

Settings Recommendations

For players targeting high refresh rates at 1920x1080, the Low preset at 222.8 FPS is the clear choice for competitive advantage, but the Medium preset at 150.9 FPS offers a better balance of visual fidelity and responsiveness without dipping below the 144 Hz threshold. The High preset at 127.2 FPS is still viable for 120 Hz displays, while Ultra at 100 FPS is best reserved for visually-focused play on slower panels. The data shows that the jump from Low to Medium costs 71.9 FPS, which is significant, but the jump from Medium to High only costs 23.7 FPS, making High the most efficient step up in quality per frame lost.

At 2560x1440, the Medium preset at 102.7 FPS is the recommended starting point, as it maintains a triple-digit frame rate while providing moderate visual improvements over Low. The High preset at 88 FPS is a solid choice for 90 Hz panels, but the Ultra preset at 67.1 FPS is only advisable for 60 Hz displays or players who prioritize image quality over smoothness. The gap between Low and Medium at 1440p is 55.3 FPS, which is substantial, but the gap between High and Ultra is only 20.9 FPS, indicating diminishing returns at the top end.

For 4K gaming, the Low preset at 90.6 FPS is the only option that approaches a smooth experience on standard 60 Hz monitors, and it is playable on 90 Hz panels. The Medium preset at 58.7 FPS is borderline, and the High preset at 52 FPS is only suitable for cinematic single-player sessions. The Ultra preset at 41.4 FPS is not recommended for any serious play, as the frame pacing will suffer. The benchmark results indicate that 4K Rust with this combo requires accepting significant visual compromises to maintain playable frame rates.

How This Combo Ranks

The combo ranks 374 out of 1717 tested combinations, placing it in the top 21.8% of all tested systems. This is a strong showing, given that the RTX 4070 sits at the 81st percentile of all GPUs and the i5-14600KF sits at the 93rd percentile of all CPUs. The rank reflects the balanced nature of this pairing, as the CPU's high single-thread performance complements the GPU's solid rasterization capabilities. The i5-14600KF's nearest rival, the Intel Core i5-14600K, scores 49166 versus 49367, a 0.4% delta, meaning the "F" variant (without integrated graphics) offers essentially identical performance. The AMD Ryzen 9 5950X trails by 0.6%, and the Intel Xeon Gold 5318H is 1.4% behind.

For the GPU, the nearest rival is the AMD Radeon RX Vega 56, which scores 37507 versus the RTX 4070's 37283, a 0.6% deficit for the NVIDIA card. The NVIDIA GeForce MX570 A is 1.9% ahead, and the RTX 4080 Mobile is 2.2% ahead, but these are laptop parts with different power envelopes. The AMD Radeon RX 5300M is 2.5% behind. This ranking data shows that the combo's 374th position is driven more by the GPU's mid-tier standing than the CPU's high-tier placement. The i5-14600KF's 93rd percentile ranking among CPUs helps push the combo into the top quarter, but the RTX 4070's 81st percentile limits its overall ceiling.

Measured FPS Breakdown

At 1920x1080, the measured average FPS across all presets shows a clear hierarchy: Low at 222.8, Medium at 150.9, High at 127.2, and Ultra at 100. The spread of 122.8 FPS between Low and Ultra is the largest of any resolution, confirming the CPU's dominance at this setting. The data shows that each preset step up from Medium costs roughly 23-24 FPS, creating a linear degradation curve.

At 2560x1440, the results are: Low at 158, Medium at 102.7, High at 88, and Ultra at 67.1. The spread narrows to 90.9 FPS, and the step from Low to Medium costs 55.3 FPS, which is a more significant hit than at 1080p. The gap between Medium and High is 14.7 FPS, and between High and Ultra is 20.9 FPS, showing a less consistent scaling pattern.

At 3840x2160, the results are: Low at 90.6, Medium at 58.7, High at 52, and Ultra at 41.4. The spread is 49.2 FPS, and the step from Low to Medium costs 31.9 FPS, which is the largest single-step penalty in the entire dataset. The gap between Medium and High is only 6.7 FPS, and between High and Ultra is 10.6 FPS. This indicates that at 4K, the GPU's memory bandwidth and shading resources are exhausted, and preset changes have less impact on frame rate.

GPU Role

The NVIDIA GeForce RTX 4070 plays a pivotal role in this combo, particularly at higher resolutions. With 12 GB of GDDR6X memory on a 192-bit bus, the card has a bandwidth of 504.2 GB/s, which is sufficient for Rust's texture streaming at 1440p but becomes strained at 4K. The memory clock runs at 1313 MHz (21 Gbps effective), and the boost clock of 2475 MHz is the key driver of the 4K Low result of 90.6 FPS. The card's 5888 shading units and 64 ROPs deliver a pixel rate of 158.4 GPixel/s, which is the primary constraint at 4K Ultra.

The GPU's 29.15 TFLOPS of FP32 compute is ample for Rust's physics and lighting calculations, but the 200 W TDP and 550 W suggested PSU indicate that power delivery is not a limiting factor in this system. The 46 RT cores and 184 tensor cores are present but unused in Rust, as the game does not heavily utilize ray tracing. The 35,800 million transistors on a 294 mm² die at 5 nm provide excellent efficiency, but the end-of-life production status suggests that newer cards will surpass it. The 81st percentile ranking against all GPUs confirms that this is a mid-to-high-tier part, and the data shows that it performs best at 1080p and 1440p, where its bandwidth and pixel rate are sufficient to keep up with the i5-14600KF's frame output.
