Rust

The Intel Core i5-14600K paired with the AMD Radeon RX 9070 delivers a performance curve in Rust that shifts dramatically depending on the resolution and quality preset selected. At 1080p, the combination produces frame rates that range from playable to exceptionally high, with the Low preset hitting an average of 214.5 FPS. Moving to 1440p, the average FPS at Low settings drops to 145.9, while the High preset yields 81.1 FPS. At 4K, the scaling becomes more punishing, with the Ultra preset averaging just 38.2 FPS and the High preset at 47.8 FPS.

The data reveals a classic resolution-scaling pattern where the GPU becomes the primary bottleneck as pixel count rises. The gap between 1080p Low and 4K Low is substantial, with the latter producing 86.1 FPS—a reduction of over 59% from the former. This indicates that while the CPU can push high framerates at lower resolutions, the RX 9070's workload increases exponentially at 4K, limiting overall performance. The difference between 1440p and 4K at Medium settings is also telling: 97.2 FPS versus 57.6 FPS, respectively, showing a steep decline that suggests the GPU is nearing its ceiling for this game's rendering demands.

Resolution Scaling

Rust's performance scaling from 1080p to 4K with this hardware combo is steep, and the limiting component shifts based on the resolution in play. At 1080p, the average FPS across all settings is high enough to suggest that the Intel Core i5-14600K is doing the heavy lifting, with the RX 9070 having headroom to spare. The jump from 1080p Low at 214.5 FPS to 1440p Low at 145.9 FPS represents a 31.9% drop, which is a typical response to a 1.78x increase in pixel count. However, the transition from 1440p Low to 4K Low—from 145.9 FPS to 86.1 FPS—is a more severe 41.0% decline, indicating that the GPU is starting to saturate its memory bandwidth and compute resources.

At higher quality settings, the scaling becomes even more pronounced. The 4K Ultra preset averages 38.2 FPS, which is less than a third of the 1080p Ultra result of 93.9 FPS. This disproportionate drop points to the RX 9070's 16 GB of GDDR6 memory and 644.6 GB/s bandwidth being tested heavily by Rust's asset streaming and draw calls at 4K. The data suggests that for smooth 4K gameplay, users would need to rely on the Low or Medium presets, as the High preset at 47.8 FPS sits below the threshold for a consistently fluid experience. The scaling behavior confirms that this is a GPU-limited scenario at higher resolutions, with the CPU playing a supporting role.

GPU Role

The AMD Radeon RX 9070's specifications directly influence the measured results in Rust. With a base clock of 1330 MHz and a boost clock of 2520 MHz, the GPU's dynamic clocking allows it to ramp up under load, but the game's optimization plays a significant role in how effectively that power is utilized. The 16 GB of GDDR6 memory on a 256-bit bus provides a theoretical bandwidth of 644.6 GB/s, which is substantial for a game like Rust that often struggles with large world maps and numerous entities. The data shows that at 4K Ultra, the average FPS of 38.2 is likely constrained by the GPU's shading units and rasterization throughput, given the 3584 shading units and 128 ROPs.

The RX 9070's RDNA 4.0 architecture, built on a 4 nm process, delivers a FP32 performance of 36.13 TFLOPS, which is ample for most titles. However, Rust's engine is known for being CPU-intensive in certain scenarios, and the benchmark results reflect a balance. At 1080p Low, the 214.5 FPS average suggests the GPU is far from being the limiting factor, as the CPU's single-thread performance takes precedence. Conversely, at 4K Ultra, the GPU's pixel fill rate of 322.6 GPixel/s is likely the bottleneck, as the game's draw calls and texture filtering demand more from the 224 TMUs. The GPU's percentile ranking of 79 among all GPUs indicates it is a capable performer, but the data shows it is not immune to the demands of high-resolution gaming in Rust.

CPU Role

The Intel Core i5-14600K brings 14 cores and 20 threads to the table, with a base clock of 3.50 GHz and a boost clock of 5.30 GHz. This configuration is well-suited for Rust, which benefits from strong single-core performance for its main game loop and physics calculations. The CPU's Cinebench R23 multi-core score of 32881 and single-core score of 4642 illustrate its strength in both threaded and single-threaded workloads. In the benchmark data, the CPU's influence is most apparent at 1080p, where the average FPS at Low settings reaches 214.5. This high framerate suggests that the CPU is capable of feeding the GPU with enough draw calls to avoid stuttering, at least at lower resolutions.

The CPU's L3 cache of 24 MB shared across the cores is another factor that helps in Rust, as the game often relies on procedural map generation and entity tracking that can benefit from larger caches. At 1440p and 4K, the CPU's role diminishes relative to the GPU, but it still ensures that frame times remain consistent. The data indicates that at 1080p Ultra, the average FPS of 93.9 is a result of the CPU maintaining frame pacing while the GPU handles the increased visual fidelity. The i5-14600K's percentile ranking of 93 among all CPUs confirms its high-end status, and the benchmark scores from PassMark (multi-thread 38682, single-thread 4270) support its capability to avoid being a bottleneck in most scenarios.

How This Combo Ranks

In the database of tested combinations, this pairing of the Intel Core i5-14600K and AMD Radeon RX 9070 holds a combo rank of 493 out of 1717 tested combos for Rust. This places it in the top 28.7% of all configurations, indicating a solidly above-average performance profile. The rank reflects the balance between the CPU's strong single-threaded capabilities and the GPU's substantial memory and compute resources. While it is not a top-tier combination, it outperforms a majority of systems in the database, which is notable given Rust's reputation for demanding both CPU and GPU resources.

Relative to other CPU options, the i5-14600K's nearest rivals in general benchmarks include the AMD Ryzen 9 5950X, which has a delta of 0.2% in average score. This suggests that in CPU-bound scenarios, the i5-14600K is competitive with a high-core-count processor. On the GPU side, the RX 9070's nearest rivals include the NVIDIA A2 with a delta of -0.2%, indicating similar raw benchmark performance. However, in Rust specifically, the combo's rank of 493 suggests that the combination's real-world performance is influenced by more than just raw benchmarks, with driver optimization and game-specific bottlenecks playing a role. The data shows that this combo is a reliable choice for high-refresh-rate 1080p gaming and capable 1440p performance, but it struggles to maintain playable framerates at 4K with high settings.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of how this combo performs across all tested configurations. At 1920x1080, the results are as follows: Low settings average 214.5 FPS, Medium settings average 144.2 FPS, High settings average 122.1 FPS, and Ultra settings average 93.9 FPS. These numbers show a clear hierarchy, with the gap between Low and Ultra being 120.6 FPS, highlighting the significant impact of quality presets on framerate at this resolution. The High preset at 122.1 FPS is more than sufficient for most monitors, and even Ultra remains above 90 FPS, making 1080p a sweet spot for this hardware.

Moving to 2560x1440, the average FPS drops across all settings: Low averages 145.9 FPS, Medium averages 97.2 FPS, High averages 81.1 FPS, and Ultra averages 61.8 FPS. The drop from 1080p to 1440p is most pronounced at Low settings, where the framerate falls by 68.6 FPS. At 1440p, the High and Ultra presets remain playable, but the margin for error shrinks, and users targeting 144 Hz will need to stick to Low or Medium settings. At 3840x2160, the performance takes a significant hit: Low averages 86.1 FPS, Medium averages 57.6 FPS, High averages 47.8 FPS, and Ultra averages 38.2 FPS. The 4K results show that this combo is only viable for 60 FPS gaming at Low settings, with Medium being borderline and High/Ultra falling below the 60 FPS threshold. This breakdown underscores the need for resolution-aware settings adjustments to achieve a smooth experience.
