Rust

Rust’s demanding survival sandbox presents a unique stress profile, and this pairing of the Intel Core i7-14700KF with the NVIDIA GeForce RTX 4090 produces a fascinating data set. The core question is whether the 20-core processor or the flagship GPU is the primary driver of frame rates across the measured presets, and the answer shifts dramatically depending on resolution and settings. The benchmark results reveal a system that is overwhelmingly powerful, yet the scaling patterns indicate that the game’s engine and CPU overhead still impose meaningful ceilings even on this high-end hardware.

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

The Intel Core i7-14700KF is a 20-core, 28-thread processor based on the Raptor Lake-R architecture, with a base clock of 3.40 GHz and a boost clock of 5.60 GHz. Its substantial L3 cache of 33 MB (shared) and dual-channel memory support for DDR4 and DDR5 suggest a design aimed at both high single-thread responsiveness and heavy multi-threaded workloads. In synthetic benchmarks, this CPU achieves a Cinebench R23 multi-core score of 44557 and a single-core score of 6290, placing it in the 96th percentile of all CPUs. This indicates that the processor’s raw throughput is exceptional, and its nearest rivals — the Intel Core i7-14700K (deltaPct 0), AMD EPYC 9115 (0.3% higher), AMD Ryzen 9 9950X (0.4% lower), and Intel Xeon Platinum 8270 (1.3% lower) — are all within a tight performance band, confirming that this chip is at the very top of the desktop heap.

For a game like Rust, which is known for heavy server-side simulation and player-driven world persistence, the CPU’s role is often more complex than raw frame generation. However, the measured FPS data here shows that at 1080p Low settings, the combo reaches 262.2 FPS average, which is a strong indicator that the CPU is capable of feeding the GPU with data at very high rates. The 28 threads provide ample headroom for background tasks, while the high boost clock of 5.60 GHz is critical for the game’s primary game thread, which often cannot fully utilize all cores. The benchmark results imply that this processor is not the bottleneck in most scenarios, as the FPS deltas between resolution changes are more pronounced, but the drop from 262.2 FPS at 1080p Low to 222.5 FPS at 1440p Low suggests that the CPU is still a limiting factor at lower resolutions where the GPU has less work to do.

How This Combo Ranks — use comboRankInGame vs other tested combos

The data places this specific CPU-GPU combination at rank 15 out of 1717 tested combos in Rust, which is a remarkable position that puts it in the 99th percentile of all systems tested. This ranking is not surprising given the individual components: the CPU is in the 96th percentile of all CPUs, and the GPU is in the 91st percentile of all GPUs. However, the rank of 15 out of 1717 also implies that there are 14 other combinations that perform better, which is likely due to the fact that Rust’s performance can be sensitive to memory configuration and specific CPU generations, or perhaps the game favors certain platform features. The deltaPct values for the CPU’s nearest rivals are all within 1.3%, meaning that swapping to a similar-tier chip like the AMD Ryzen 9 9950X would likely yield a negligible change in overall system performance. The GPU’s rivals, such as the NVIDIA Tesla T4 (deltaPct -0.4) and AMD Radeon Pro Vega 56 (deltaPct -0.9), are not gaming-grade parts, so the RTX 4090’s dominance in this context is clear. This rank suggests that while the hardware is near the top, there is still a small headroom for other configurations to edge out better results, possibly due to the game’s engine quirks.

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

At 1920x1080, the combo delivers a broad spread of results. Low settings yield an average of 262.2 FPS, while Medium drops to 214.8 FPS, High settles at 180.7 FPS, and Ultra falls to 138.9 FPS. This shows a clear degradation of ~123 FPS from Low to Ultra, a 47% reduction. Moving to 2560x1440, the averages are 222.5 FPS (Low), 148.6 FPS (Medium), 122.7 FPS (High), and 93.9 FPS (Ultra). The gap between Low and Ultra at 1440p is 128.6 FPS, which is a slightly larger absolute drop than at 1080p, indicating that the GPU is starting to feel the load. At 3840x2160, the numbers compress significantly: Low produces 129.2 FPS, Medium drops to 86.6 FPS, High yields 77.1 FPS, and Ultra bottoms out at 58 FPS. The delta from Low to Ultra at 4K is 71.2 FPS, which is a smaller absolute number but a larger percentage reduction (55%). This pattern indicates that at higher resolutions, the GPU becomes the dominant factor, while at lower resolutions, the CPU’s ability to process game logic is more exposed, as seen in the 1080p Low result of 262.2 FPS.

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

The transition from 1920x1080 to 3840x2160 reveals a significant scaling curve. At Low settings, the FPS drops from 262.2 at 1080p to 222.5 at 1440p (a 15% decrease) and then to 129.2 at 4K (a 42% decrease from 1440p). This steep drop from 1440p to 4K at Low settings suggests that the GPU is becoming the limiting factor, as the CPU’s workload does not change much with resolution. At High settings, the drop is from 180.7 FPS at 1080p to 122.7 FPS at 1440p (a 32% decrease) and then to 77.1 FPS at 4K (a 37% decrease from 1440p). The percentage drops are more consistent at High settings, indicating a more balanced load between CPU and GPU. At Ultra settings, the FPS goes from 138.9 at 1080p to 93.9 at 1440p (a 32% decrease) and then to 58 at 4K (a 38% decrease). The fact that the 1080p to 1440p drop is around 32% for both High and Ultra, but only 15% for Low, is telling. It implies that at Low settings, the CPU is still able to push high frame rates, but the GPU is not yet saturated; however, once settings increase, the GPU load grows, and the scaling becomes more linear. The 4K results, especially at Ultra (58 FPS), show that the RTX 4090 is working hard, but the CPU is no longer the primary bottleneck at this resolution.

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

Analyzing the measured rows, the optimal preset depends on the target resolution and refresh rate. At 1920x1080, the High preset at 180.7 FPS is the best balance, as it provides a high frame rate that is well above the 144 Hz refresh rate of most gaming monitors, while still offering improved visual fidelity over Low (262.2 FPS) and Medium (214.8 FPS). The Ultra preset at 138.9 FPS is also playable, but the drop below 144 FPS makes High the better choice for competitive play. At 2560x1440, the Medium preset at 148.6 FPS appears to be the sweet spot, as it remains above 144 FPS and is a significant jump over High (122.7 FPS) which dips below that threshold. The Ultra preset at 93.9 FPS is still smooth for less competitive scenarios, but Medium offers the best frame rate per visual quality trade-off. At 3840x2160, the High preset at 77.1 FPS is the recommended choice, as it is the only preset that stays above 60 FPS while providing a substantial visual upgrade over Medium (86.6 FPS) and Low (129.2 FPS). The Ultra preset at 58 FPS is technically playable but may feel less responsive, so High is the best pick for a 4K experience that prioritizes both smoothness and fidelity. Overall, the data suggests that High or Medium presets are the most versatile, with Low reserved for maximum competitive frame rates and Ultra for those who prioritize visuals over frame speed.

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

The NVIDIA GeForce RTX 4090 is a behemoth, built on the Ada Lovelace architecture with a 5 nm process node and 76,300 million transistors. Its boost clock of 2520 MHz, combined with 16384 shading units and 128 RT cores, provides immense raw compute power, as evidenced by its 82.58 TFLOPS FP32 performance. The 24 GB of GDDR6X memory on a 384-bit bus delivers 1.01 TB/s of bandwidth, which is critical for high-resolution textures and large game worlds like Rust’s. The GPU’s average benchmark score of 66473 places it in the 91st percentile of all GPUs, with its nearest rivals being professional workstation cards like the NVIDIA Tesla T4 (deltaPct -0.4) and AMD Radeon Pro Vega 56 (deltaPct -0.9), which are not designed for gaming. In the measured results, the RTX 4090’s role is clear: at 4K Ultra, it produces 58 FPS, which is the lowest result, showing that even this flagship GPU is challenged by the game’s most demanding settings. However, at 1080p Low, it achieves 262.2 FPS, proving that when the CPU is not the bottleneck, the GPU can deliver extremely high frame rates. The data suggests that the RTX 4090 is never the limiting factor at 1080p, but at 4K Ultra, it is working at its limits, and the frame rate is dictated by the GPU’s ability to process the increased pixel count and visual effects. The 24 GB VRAM is more than sufficient for Rust, and the memory bandwidth of 1.01 TB/s ensures that texture streaming at 4K does not cause stutters, as evidenced by the stable 77.1 FPS average at 4K High.
