Rust

Rust’s measured frame rates for the Intel Core i5-14600K paired with the AMD Radeon RX 7700 show a steep performance cliff as resolution climbs. At 1920x1080 with Low settings, the combo produces 173 FPS average. Moving to 2560x1440 drops that figure to 119 FPS, a reduction of roughly 31%. At 3840x2160, the same Low preset yields only 70 FPS, which is 59% below the 1080p result. This scaling pattern indicates that the Radeon RX 7700 becomes the primary bottleneck at higher pixel counts, as the CPU’s headroom at 1080p cannot compensate for the GPU’s rendering load at 4K.

The gap widens further when comparing presets at each resolution. At 1080p, Low delivers 173 FPS, while Ultra falls to 75 FPS, a 57% drop. At 1440p, the spread is similar in percentage terms: Low hits 119 FPS, Ultra manages 51 FPS, a 57% decline. At 4K, the difference becomes more pronounced in absolute terms, with Low at 70 FPS and Ultra at just 30 FPS, a 57% reduction. The consistency of this percentage drop across resolutions suggests that the GPU’s shading and memory throughput scale predictably with settings, but the absolute numbers reveal that 4K Ultra is effectively unplayable for smooth action.

The frame pacing data available for Medium settings reinforces this trend. At 1080p Medium, the average is 116 FPS with a minimum of 99 FPS and a maximum of 133 FPS, showing tight variance. At 1440p Medium, the average falls to 80 FPS, with a minimum of 68 FPS and a maximum of 92 FPS. At 4K Medium, the average is 47 FPS, with a minimum of 40 FPS and a maximum of 54 FPS. The minimum-to-maximum spread at 4K Medium is 14 FPS, which is proportionally larger than at 1080p, indicating less stable frame delivery under heavy load.

Resolution Scaling

The data shows that Rust’s performance with this hardware is heavily resolution-bound. From 1080p Low to 4K Low, the average FPS drops by 103 frames, a 60% reduction. This is a classic sign that the RX 7700’s compute units are saturated as pixel count quadruples from 1080p to 4K. The CPU, with its 14 cores and 20 threads, has ample headroom to feed the GPU at lower resolutions, but at 4K, the GPU’s 16 GB of GDDR6 memory and 256-bit bus are working at their limits.

The scaling from 1440p to 4K is particularly punishing. At High settings, 1440p yields 67 FPS, while 4K yields 40 FPS, a 40% reduction. At Ultra settings, 1440p produces 51 FPS, while 4K produces 30 FPS, a 41% reduction. This suggests that even the RX 7700’s 624.1 GB/s memory bandwidth cannot offset the sheer number of pixels at 4K. Players targeting 60 FPS should avoid 4K entirely, as only the Low preset at 4K reaches 70 FPS, and that is marginal.

The 1080p to 1440p transition is more forgiving. At High settings, the drop is from 98 FPS to 67 FPS, a 32% reduction. At Low settings, the drop is from 173 FPS to 119 FPS, a 31% reduction. This indicates that 1440p remains viable for high-refresh monitors, provided settings are kept at Medium or below. The 1080p results show that this combination is capable of exceeding 170 FPS only at the lowest settings, which is essential for competitive play.

CPU Role

The Intel Core i5-14600K is a 14-core, 20-thread processor based on Raptor Lake architecture, with a base clock of 3.50 GHz and a boost clock of 5.30 GHz. Its benchmark scores position it in the 90th percentile of all CPUs, with an average benchmark score of 48618. This places it slightly behind the Intel Xeon Gold 5318H (deltaPct -0.2) and Intel Core Ultra 5 245 (deltaPct -0.8), but ahead of the AMD EPYC 4345P (deltaPct 0.3) and Intel Core Ultra 5 245HX (deltaPct 0.7). For Rust, which is known to stress single-thread performance for game logic, the 5.30 GHz boost clock is critical.

The CPU’s 24 MB of shared L3 cache and dual-channel memory support (DDR4 and DDR5) contribute to its ability to handle Rust’s world streaming and entity interactions. In the measured FPS data, the CPU’s influence is most visible at 1080p Low, where the 173 FPS result suggests that the processor is not the limiting factor. Even at 1080p Ultra, the 75 FPS figure is likely constrained by the GPU rather than the CPU, as the RX 7700’s rasterization throughput becomes the bottleneck.

However, the CPU’s role becomes more apparent when examining the frame rate consistency at lower resolutions. The 1080p Medium results show a minimum of 99 FPS and a maximum of 133 FPS, a spread of 34 FPS. This variance is typical of Rust’s physics and NPC simulation, which can cause brief CPU-bound hitches. The i5-14600K’s 20 threads provide enough parallel capacity to mitigate severe drops, but the data shows that even this strong processor cannot eliminate all frame time spikes in a survival game with complex world state.

GPU Role

The AMD Radeon RX 7700, built on RDNA 3.0 architecture with a Navi 32 chip, is the clear performance limiter in this pairing at higher resolutions. It features 16 GB of GDDR6 memory on a 256-bit bus, delivering 624.1 GB/s of bandwidth. Its boost clock of 2459 MHz and game clock of 2041 MHz drive 2560 shading units, 160 texture mapping units, and 96 raster output units. The GPU’s benchmark percentile is 58th among all GPUs, with an average score of 15852, placing it near the AMD Radeon R9 370X (deltaPct -0.1) and AMD Radeon RX 9060 (deltaPct -1), while trailing the NVIDIA GeForce RTX 3060 Ti (deltaPct -1.7).

In Rust, the GPU’s 16 GB VRAM is a substantial advantage, as the game can consume large amounts of memory for textures and draw distances. However, the measured FPS data shows that the GPU’s raw compute power is insufficient for 4K Ultra, where it delivers only 30 FPS. At 4K Medium, the 47 FPS average with a 40 FPS minimum indicates that the GPU is struggling to maintain playable frame rates even at moderate settings. The 4K Low result of 70 FPS is the only 4K preset that approaches smoothness, and it still falls short of 75 FPS.

The GPU’s performance at 1440p is more respectable. High settings yield 67 FPS, Medium yields 80 FPS, and Low yields 119 FPS. These numbers suggest that 1440p is the sweet spot for this card in Rust, provided users accept Medium or High presets. The 1080p results, with Low at 173 FPS and Medium at 116 FPS, confirm that the RX 7700 can drive high-refresh 1080p panels without issue, but the Ultra preset at 75 FPS shows the card’s limits when ray tracing or advanced effects are enabled.

How This Combo Ranks

The Intel Core i5-14600K and AMD Radeon RX 7700 combination ranks 1728th out of 3723 tested combos in Rust. This places it in the 46th percentile of all combos, meaning roughly 54% of tested configurations deliver higher average FPS in this game. The ranking reflects the GPU’s mid-range positioning; the CPU is top-tier, but the GPU’s 58th percentile benchmark score drags the overall combo down. For context, the RX 7700’s nearest rivals in GPU benchmarks include the R9 370X and RX 9060, which are not typical gaming partners for a 14th-gen Core i5.

The combo’s rank suggests that it is a balanced pairing for 1080p and 1440p gaming, but not for 4K. In the context of all tested combos, the 1728th rank means there are 1,727 configurations that perform better, many of which likely pair the i5-14600K with higher-tier GPUs. Conversely, there are 1,995 combos that perform worse, indicating that this setup is firmly mid-pack. The data shows that the bottleneck is the GPU, as upgrading to a faster card would yield significant FPS gains, particularly at 4K.

The deltaPct values for the GPU’s nearest rivals highlight its competitive position. The RX 7700 is 1% slower than the RX 9060 and 1.7% slower than the RTX 3060 Ti, but 1.1% faster than the Radeon Pro W5500. These small differences in synthetic benchmarks translate to similar performance in Rust, meaning users should not expect large frame rate gaps between these cards. The combo’s rank in Rust specifically, rather than in synthetic tests, is the more relevant metric for gameplay.

Settings Recommendations

Based on the measured FPS rows, the optimal experience for this combo depends on the target resolution. For 1920x1080, the Medium preset delivers 116 FPS average with a 99 FPS minimum, which is ideal for high-refresh monitors. The Low preset at 173 FPS may be preferable for competitive play, but Medium offers a better balance of visual fidelity and smoothness. The High preset at 98 FPS is also viable, while Ultra at 75 FPS is playable but may dip below 60 FPS in busy areas.

For 2560x1440, the Medium preset is the best choice, yielding 80 FPS average with a 68 FPS minimum. This keeps frame rates above 60 FPS in most scenarios, while High drops to 67 FPS and Ultra falls to 51 FPS, which risks stuttering. The Low preset at 119 FPS is excellent for high-refresh 1440p monitors, but it sacrifices significant visual quality. Users with 1440p 144Hz displays should favor Low or Medium.

For 3840x2160, the data strongly recommends against Ultra, which averages 30 FPS. The Medium preset at 47 FPS is borderline, with a 40 FPS minimum that will cause noticeable judder. The Low preset at 70 FPS is the only 4K option that approaches acceptable playability, but it still fails to maintain 75 FPS. Players with 4K displays should either lower resolution to 1440p or accept the visual compromises of the Low preset.

Measured FPS Breakdown

At 3840x2160, the measured results are as follows: Low averages 70 FPS, Medium averages 47 FPS with a minimum of 40 FPS and a maximum of 54 FPS, High averages 40 FPS, and Ultra averages 30 FPS. The Medium preset’s 14 FPS spread between minimum and maximum indicates uneven frame pacing, which is typical of GPU-bound scenarios in Rust.

At 2560x1440, the results improve substantially: Low averages 119 FPS, Medium averages 80 FPS with a minimum of 68 FPS and a maximum of 92 FPS, High averages 67 FPS, and Ultra averages 51 FPS. The Medium preset shows a 24 FPS spread, which is more stable than at 4K but still noticeable during rapid camera movement.

At 1920x1080, the combo performs at its best: Low averages 173 FPS, Medium averages 116 FPS with a minimum of 99 FPS and a maximum of 133 FPS, High averages 98 FPS, and Ultra averages 75 FPS. The Medium preset’s 34 FPS spread is the largest of any resolution, suggesting that the CPU’s thread scheduling and the GPU’s frame generation are slightly out of sync at this setting. However, the absolute numbers are high enough that this variance is rarely perceptible in practice.
