Rust

The Intel Core i7-14700K and AMD Radeon RX 6800 XT combination delivers a solid 1080p and 1440p experience in Rust, with 4K Ultra proving to be the only setting where the frame rate dips below playable thresholds. The pairing leverages a high-core-count CPU with a capable RDNA 2 GPU, though the data reveals a clear shift in bottleneck behavior as resolution and graphical fidelity increase. This analysis breaks down the measured performance of this specific combo across all tested settings and resolutions, placing it in context within the broader benchmark database.

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

The Intel Core i7-14700K is a 20-core, 28-thread processor based on the Raptor Lake architecture, built on Intel's 10 nm process. It features a base clock of 3.40 GHz and a boost clock of 5.60 GHz, with a 125 W TDP and support for both DDR4 and DDR5 memory. The CPU's cache hierarchy includes 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3 cache. Its benchmark results show a strong single-thread performance, with a Geekbench single-core score of 2569 and a Cinebench R23 single-core score of 2160. Multi-threaded performance is equally robust, as evidenced by a Cinebench R23 multi-core score of 33440.5 and a Geekbench multi-core score of 20767. The CPU holds a 94th percentile ranking versus all CPUs, indicating it outperforms the vast majority of processors in the database.

In Rust, which is known for its demanding server-side simulation and physics calculations, the 14700K's high boost clock and substantial core count are critical assets. The game's performance at lower resolutions and settings is often dictated by CPU throughput, and the data supports this: at 1080p Low, the combo achieves 209 FPS, which is the highest average FPS recorded across all tested configurations. This suggests that at this setting, the CPU is able to feed the GPU with enough data to prevent it from becoming the limiting factor. The CPU's nearest rivals in the database include the AMD Ryzen 9 7950X, which has an average score of 69515 (0.2% higher than the 14700K's 69355), and the AMD Ryzen 9 7940HX, which scores 69875 (0.7% higher). These marginal deltas indicate that the 14700K is positioned at the top tier of CPU performance, which is essential for maintaining high frame rates in Rust's most CPU-intensive scenarios.

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

The AMD Radeon RX 6800 XT is built on the RDNA 2.0 architecture and features 16 GB of GDDR6 memory on a 256-bit bus, delivering a memory bandwidth of 512.0 GB/s. Its base clock is 1825 MHz, with a boost clock of 2250 MHz and a game clock of 2015 MHz. The GPU contains 4608 shading units, 288 TMUs, and 128 ROPs, with a FP32 performance of 20.74 TFLOPS. It supports DirectX 12 Ultimate, Vulkan 1.4, and OpenGL 4.6. The GPU's benchmark scores include a Geekbench OpenCL score of 171304 and a PassMark G3D score of 24980, placing it in the 85th percentile versus all GPUs. Its nearest rivals include the NVIDIA GeForce RTX 5070 Ti, which has an average score of 49957 (3% higher than the RX 6800 XT's 48477), and the Intel Arc A550M, which scores 49737 (2.5% higher).

In Rust, the GPU's role becomes more pronounced at higher resolutions and graphical settings. The 16 GB VRAM capacity is particularly relevant for Rust, as the game's large, persistent worlds can consume significant texture memory at Ultra settings. At 4K Ultra, the combo drops to 37 FPS, which is a substantial decrease from the 48 FPS at 4K High. This indicates that the GPU is the primary bottleneck at this resolution and setting, as the increased pixel count and texture detail overwhelm the RX 6800 XT's processing capabilities. Conversely, at 1080p Low, the GPU is underutilized, allowing the CPU to drive the frame rate to 209 FPS. The data shows that the RX 6800 XT is well-suited for 1440p gaming in Rust, where it maintains 62 FPS at Ultra and 82 FPS at High, but struggles to maintain playable frame rates at 4K Ultra.

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

The measured FPS data reveals a clear scaling pattern across resolutions. At 1080p Low, the combo achieves 209 FPS, which drops to 144 FPS at 1440p Low and further to 85 FPS at 4K Low. This represents a 59% reduction in frame rate from 1080p to 4K at Low settings. At High settings, the drop is from 119 FPS at 1080p to 82 FPS at 1440p and 48 FPS at 4K, a 60% decrease. The Medium settings show a similar trend: 140 FPS at 1080p, 97 FPS at 1440p, and 57 FPS at 4K, a 59% drop. At Ultra settings, the frame rates are 90 FPS at 1080p, 62 FPS at 1440p, and 37 FPS at 4K, a 59% reduction.

The consistency of this ~59% drop across all settings suggests that the performance scaling is primarily driven by the GPU's pixel throughput capabilities. The RX 6800 XT's 512.0 GB/s memory bandwidth and 20.74 TFLOPS of FP32 compute are the key factors in this scaling. As resolution increases, the GPU must process more pixels and access more texture data, which directly impacts its frame rate. The CPU's role in this scaling is less significant, as the 14700K's strong single-thread performance ensures that it can keep up with the GPU's demands even at lower resolutions. However, the fact that 1080p Low yields 209 FPS while 4K Low yields 85 FPS indicates that the GPU is the limiting component in all scenarios, even at Low settings where the CPU would typically be more stressed. This is a notable finding, as it suggests that in Rust, the RX 6800 XT is the primary bottleneck for this combo, and upgrading the GPU would yield more significant frame rate gains than upgrading the CPU.

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

The measured FPS data for this combo provides a comprehensive view of its performance across three resolutions and four settings levels. At 1080p, the combo delivers the highest frame rates, with Low settings producing an average of 209 FPS. Medium settings at this resolution yield 140 FPS, with a minimum of 119 FPS and a maximum of 162 FPS. High settings drop the average to 119 FPS, while Ultra settings bring it down to 90 FPS. This range from 90 to 209 FPS at 1080p demonstrates that the combo is capable of high refresh rate gaming at this resolution, even at the most demanding settings.

Moving to 1440p, the frame rates decrease but remain respectable. Low settings produce an average of 144 FPS, which is still suitable for high refresh rate monitors. Medium settings yield 97 FPS, with a minimum of 82 FPS and a maximum of 111 FPS. High settings average 82 FPS, and Ultra settings drop to 62 FPS. The 1440p Ultra result of 62 FPS is the first sign of the GPU being pushed to its limits, but it remains playable for most users. At 4K, the performance drops significantly. Low settings average 85 FPS, Medium settings average 57 FPS, High settings average 48 FPS, and Ultra settings drop to 37 FPS. The 4K Medium result includes a minimum FPS of 49 and a maximum of 66, indicating some frame time variance. The 4K Ultra result of 37 FPS is the lowest measured value for this combo and would be considered borderline for competitive play, though it may be acceptable for slower-paced survival gameplay.

How This Combo Ranks — use comboRankInGame vs other tested combos

In the benchmark database, this specific combination of the Intel Core i7-14700K and AMD Radeon RX 6800 XT ranks 1118th out of 3723 tested combos in Rust. This places it in the top 30% of all tested configurations, which is a strong showing given the wide variety of hardware combinations in the database. The rank is influenced by both the CPU's and GPU's individual performance, but the data suggests that the GPU's limitations at 4K Ultra are the primary factor preventing a higher ranking. The CPU's 94th percentile ranking versus all CPUs and the GPU's 85th percentile ranking versus all GPUs indicate that both components are above average, but the combo's overall rank is constrained by the GPU's performance at higher resolutions.

Compared to other combos in the database, this pairing is positioned well for 1080p and 1440p gaming, where it achieves frame rates that would satisfy most players. The rank of 1118 out of 3723 suggests that there are many combos with either a more powerful GPU or a more balanced CPU-GPU pairing that outperform it in Rust, particularly at 4K. However, the combo's performance at 1080p Low (209 FPS) and 1440p Low (144 FPS) indicates that it is well-suited for high refresh rate gaming at these resolutions. The data also shows that the combo's performance is more consistent at lower settings, which is typical for a system where the GPU is the limiting factor. Overall, the rank reflects a capable but not top-tier configuration for Rust, with the GPU being the primary area for potential improvement.
