Rust

The Intel Core i7-14700KF paired with the AMD Radeon RX 570 produces a severely GPU-bound experience in Rust, where the 20-core processor’s substantial compute headroom is left largely unused at every resolution and settings level tested. The measured frame rates show a component mismatch of unusual magnitude: the CPU ranks in the 94th percentile among all processors, while the GPU sits in the 74th percentile, yet the combined system ranks 3553rd out of 3723 tested combos. This pairing delivers playable performance only at 1080p with Low settings, and the data indicates that the RX 570 is the definitive bottleneck across the entire measurement matrix.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep and consistent across all settings, confirming that the Radeon RX 570 is the limiting component. At Low settings, the average FPS falls from 66 at 1920x1080 to 46 at 2560x1440, a 30% reduction, and then to 27 at 3840x2160, a further 41% drop from the 1440p figure. This scaling pattern is characteristic of a GPU that is saturated by pixel throughput, not a CPU that is struggling with game logic.

At Medium settings, the same trend appears with slightly lower absolute numbers: 44 FPS at 1080p, 31 FPS at 1440p, and 18 FPS at 4K. The 4K result here includes a minimum FPS of 15 and a maximum of 21, showing that even the average is near the edge of playability. High settings produce 38 FPS at 1080p, 26 FPS at 1440p, and 15 FPS at 4K, while Ultra settings yield 29, 20, and 12 FPS respectively. The 4K Ultra result of 12 FPS is the lowest measured value in the entire dataset.

The resolution scaling behavior indicates that the RX 570’s 224.0 GB/s memory bandwidth and 5.095 TFLOPS of FP32 compute are insufficient for Rust’s renderer at higher pixel counts. The gap between 1080p and 1440p is proportionally larger than the gap between 1440p and 4K at most settings, which suggests that the GPU’s fill rate and shading units hit a wall relatively early. The 4K numbers are uniformly below 30 FPS, making that resolution effectively unplayable regardless of quality preset.

GPU Role

The AMD Radeon RX 570 is a Polaris 20 part built on a 14 nm process, with 2048 shading units, 128 texture mapping units, and 32 render output units. Its clock speeds are modest, with a base of 1168 MHz and a boost of 1244 MHz, driving a pixel rate of 39.81 GPixel/s and a texture rate of 159.2 GTexel/s. The 4 GB of GDDR5 memory on a 256-bit bus provides 224.0 GB/s of bandwidth, which is the key constraint at higher resolutions.

In Rust, the GPU’s role is dominated by memory bandwidth and raw pixel throughput. The measured FPS at 1080p Low (66 FPS) is the only result that approaches a smooth experience, and even that figure is modest by modern standards. The 4 GB VRAM capacity is likely a limiting factor at Ultra settings, where the 29 FPS at 1080p and 12 FPS at 4K suggest that texture memory pressure compounds with the shader workload. The benchmark results show that the RX 570’s performance is consistently below what the CPU can feed it, with the GPU percentile of 74 versus the CPU’s 94 highlighting the imbalance.

The nearest rivals to the RX 570 in aggregate benchmark scores include the AMD Radeon RX 6800M (0.4% faster) and the AMD Radeon RX 470 (0.8% slower), which places this GPU in a performance class that is clearly not designed for Rust at high resolutions. The 1750 MHz memory clock, listed as 7 Gbps effective, is fixed across all tests and does not scale, so the only variable the user can control is the settings preset, which trades visual quality for frame rate.

CPU Role

The Intel Core i7-14700KF provides 20 cores and 28 threads across a Raptor Lake-R architecture, with a base clock of 3.40 GHz and a boost clock of 5.60 GHz. Its 33 MB of shared L3 cache and dual-channel memory support are ample for Rust’s single-threaded server logic and physics. However, the measured FPS data shows that the CPU is never the bottleneck in this pairing, even at 1080p Low where the GPU is at its least stressed.

Benchmark scores for the i7-14700KF include a Cinebench R23 multi-core score of 44167, a Geekbench single-core score of 2578, and a PassMark single-thread score of 4480. The processor’s 94th percentile ranking among all CPUs places it in the top tier of desktop parts, with nearest rivals including the AMD Ryzen 9 7950X (0.9% slower) and the Intel Core Ultra 7 265K (1% faster). None of this compute power translates into higher frame rates in Rust because the RX 570 saturates well before the CPU’s threads are fully utilized.

The CPU’s 125 W TDP and 10 nm process node are irrelevant to the gaming results here, as the data shows consistent frame rates that scale almost entirely with GPU settings and resolution. At 1080p Low, the 66 FPS average is likely near the ceiling of what the RX 570 can produce, while the CPU could theoretically handle far more. The 20-core configuration is overkill for Rust’s typical thread usage, and the benchmark results reflect that the processor contributes nothing to the FPS variance across the tested matrix.

Measured FPS Breakdown

At 1920x1080, the RX 570 delivers its best performance. Low settings produce an average of 66 FPS, which is the only result above 60 in the entire dataset. Medium settings average 44 FPS, with a minimum of 38 and a maximum of 51, indicating some frame pacing variance. High settings average 38 FPS, and Ultra settings drop to 29 FPS. These numbers show a clear progression where each settings tier costs roughly 15-20% of the frame rate.

At 2560x1440, the averages fall across the board. Low settings yield 46 FPS, a 30% drop from 1080p. Medium settings average 31 FPS, with a minimum of 26 and a maximum of 35. High settings average 26 FPS, and Ultra settings produce 20 FPS. The 1440p results are borderline playable only at Low settings, and even then, the 46 FPS average is below the 60 FPS threshold that most players prefer.

At 3840x2160, the GPU is overwhelmed. Low settings average 27 FPS, Medium averages 18 FPS (with a minimum of 15 and maximum of 21), High averages 15 FPS, and Ultra averages 12 FPS. No 4K configuration reaches 30 FPS, making this resolution unsuitable for any gameplay. The 4K Medium result’s minimum of 15 FPS and maximum of 21 FPS show a narrow band that is consistently unplayable.

The measured rows include only average FPS for most settings, with min/max data provided solely for the Medium preset at each resolution. This limited data suggests that Medium is the only preset where frame pacing was tracked, and the 1080p Medium numbers (38 min, 51 max) show a wider spread than the 1440p Medium (26 min, 35 max) or 4K Medium (15 min, 21 max), indicating that the GPU’s frame output becomes more consistent as it saturates.

How This Combo Ranks

The combination of the Intel Core i7-14700KF and AMD Radeon RX 570 ranks 3553rd out of 3723 tested combos in Rust, placing it in the bottom 5% of all systems. This rank is remarkably low given the CPU’s 94th percentile standing and the GPU’s 74th percentile, illustrating that the pairing is fundamentally unbalanced for this game. The data shows that the GPU holds the system back to a degree that the CPU’s power cannot compensate for.

In context, the i7-14700KF’s nearest rivals in CPU benchmarks are all within 1% of its average score, yet none of that margin matters here because the RX 570 is the performance ceiling. The GPU’s nearest rivals include the RX 6800M (0.4% faster) and the R9 M295X (0.7% slower), all of which would likely produce similar Rust results due to the same VRAM and bandwidth constraints. The combo rank reflects that Rust’s demands are primarily GPU-centric, and the 4 GB VRAM and 224.0 GB/s bandwidth of the RX 570 are simply inadequate for the game’s rendering load.

The rank of 3553 out of 3723 means that only 170 tested combos perform worse, which is a striking result for a system with a top-tier CPU. This suggests that users who upgrade the GPU while keeping the i7-14700KF would see dramatic improvements, whereas upgrading the CPU alone would yield no measurable gain in Rust based on the current data. The combo’s placement is a direct consequence of the GPU’s limits, not the CPU’s capabilities.

Settings Recommendations

Based on the measured FPS rows, the only configuration that provides a playable experience is 1920x1080 with Low settings, which averages 66 FPS. This is the sole preset above the 60 FPS threshold, and it is the recommended choice for any user prioritizing smooth gameplay. The 1080p Medium preset at 44 FPS is acceptable for less demanding players, but the 38 FPS minimum indicates occasional dips that could be noticeable in combat.

At 2560x1440, Low settings at 46 FPS is the only viable option, but it falls short of the 60 FPS target and may feel inconsistent. The 1440p Medium preset at 31 FPS is playable for casual exploration but not recommended for fast-paced scenarios. All 4K presets, ranging from 12 to 27 FPS, are unsuitable for any form of gameplay and should be avoided entirely.

The data suggests that the RX 570’s 4 GB VRAM is a hard limit at Ultra settings, where even 1080p drops to 29 FPS. Users should stick to Low or Medium at 1080p, with Low being the only preset that consistently delivers smooth frame rates. The 66 FPS at 1080p Low is the best measured result, and it is the benchmark against which all other settings are compared.
