Rust

Rust, a survival title that launched in 2018, continues to demand significant hardware resources. The pairing of the Intel Core i9-14900K and the AMD Radeon RX 6700 XT produces a distinctive performance profile that is heavily dependent on both resolution and quality settings. The measured data reveals a combination that can deliver high frame rates at 1080p but struggles to maintain smooth performance at 4K, particularly with higher graphical presets.

How This Combo Ranks

The Intel Core i9-14900K and AMD Radeon RX 6700 XT combination ranks 920th out of 1717 tested combos for this game. This places the pairing squarely in the middle of the performance distribution. While the rank might seem modest, it is important to consider that this list includes all possible CPU and GPU pairings, many of which feature significantly more powerful graphics cards. The data indicates that the primary limitation for this specific combo in Rust is the GPU, which means its overall rank is more a reflection of the graphics card's tier than the CPU's capability.

Benchmark analysis shows the Core i9-14900K is a top-tier processor, sitting in the 97th percentile against all CPUs. Its average benchmark score of 79824 places it in direct competition with the AMD EPYC 7413, which is only 0.3% faster, and the Intel Core i9-14900KF, which is 0.7% slower. This positions the CPU as a non-factor in most gaming scenarios, as it provides ample headroom. The rank of the entire combo, therefore, is dragged down by the RX 6700 XT, which sits in the 77th percentile for GPUs. The GPU's average benchmark score of 33721 is closely matched by the AMD Radeon RX 6800, which is a mere 0.7% faster, and the NVIDIA RTX A5000, which is 1.3% slower. In essence, this is a high-end CPU paired with a mid-range GPU, and the data shows that Rust's frame rates will be dictated by the latter.

GPU Role

The AMD Radeon RX 6700 XT is built on the RDNA 2.0 architecture and utilizes the Navi 22 chip, manufactured on a 7 nm process by TSMC. It has a die size of 335 mm² and contains 17,200 million transistors. The card's memory configuration consists of 12 GB of GDDR6 memory on a 192-bit bus, providing a bandwidth of 384.0 GB/s. The GPU has a base clock of 2321 MHz, a game clock of 2424 MHz, and a boost clock of 2581 MHz.

In the context of Rust, the GPU's role becomes the defining factor for performance. The measured FPS data shows a clear pattern where the RX 6700 XT becomes the bottleneck as resolution and settings increase. The card's 2560 shading units and 64 ROPs are put under immense strain at higher resolutions. While it can handle the lower graphical loads at 1080p, the transition to 4K reveals its limitations, with the average frame rate dropping below 40 FPS on High settings. The GPU also supports DirectX 12 Ultimate, which Rust can leverage, but the raw compute power of 13.21 TFLOPS FP32 is not sufficient to maintain high frame rates at the most demanding settings. The card's texture rate is 413.0 GTexel/s, and its pixel rate is 165.2 GPixel/s, figures that are adequate for 1080p but insufficient for the pixel count of 4K.

Resolution Scaling

The data shows a significant and consistent drop in frame rates as resolution increases from 1920x1080 to 3840x2160. This scaling behavior is a classic indicator of GPU-bound performance. At 1080p Low settings, the combo achieves 166.9 FPS. Moving to 1440p Low, this drops to 112.9 FPS, a 32% decrease. At 4K Low, the frame rate falls to 65.7 FPS, which is a further 42% decrease from 1440p. The pattern is similar for High settings, where the frame rate goes from 92.2 FPS at 1080p, to 67.8 FPS at 1440p, and finally to 37.8 FPS at 4K.

This steep decline indicates that the RX 6700 XT is the limiting component. The CPU, with its 24 cores and 32 threads, is not the bottleneck in these scenarios. The i9-14900K's massive processing power, evidenced by its 49872 score in Cinebench R23 multi-core, is more than capable of feeding the GPU at any resolution. The frame rate drops are directly proportional to the increase in pixel count, which is the signature of a GPU that has reached its rendering capacity. The data shows that for a smooth 60 FPS experience, the user must either stay at 1080p or 1440p with lower settings, as the 4K resolution consistently pushes the GPU past its limits.

Measured FPS Breakdown

The measured FPS data provides a detailed look at the combo's performance across a grid of resolutions and settings.

At 1920x1080, the combo performs admirably. On Low settings, it achieves an average of 166.9 FPS, which is exceptionally high. Medium settings still allow for a very playable 113.5 FPS. High settings yield 92.2 FPS, which is smooth for most players. Ultra settings, however, bring the average down to 68.9 FPS, showing a significant performance cost for the highest graphical quality.

Moving to 2560x1440, the strain on the GPU becomes more evident. The Low preset produces an average of 112.9 FPS, still a strong result. The Medium preset drops to 74.9 FPS. High settings average 67.8 FPS, which is acceptable but shows a clear step down from 1080p. Ultra settings at 1440p result in an average of 51.4 FPS, which is below the ideal threshold for fast-paced gameplay.

At 3840x2160, the RX 6700 XT is clearly overburdened. Low settings manage an average of 65.7 FPS, which is playable but not ideal. The Medium preset falls to 44.7 FPS. High settings average only 37.8 FPS, which is a challenging experience. Ultra settings bring the average down to 28.9 FPS, which is not a viable configuration for smooth play. The data shows a clear hierarchy: the combo is best suited for 1080p gaming, is adequate for 1440p with adjustments, and is not recommended for 4K beyond the lowest settings.

CPU Role

The Intel Core i9-14900K is a flagship desktop processor from the Core 14th Gen series. It features 24 cores and 32 threads, with a base clock of 3.20 GHz and a boost clock of 6.00 GHz. The processor is built on the Raptor Lake architecture and uses a 10 nm process node. It has a substantial L3 cache of 36 MB shared, along with 2 MB of L2 cache per core and 80 KB of L1 cache per core. Its benchmark scores are exceptional, with a Geekbench single-core score of 3064 and a multi-core score of 20370.

In the context of Rust, the CPU's role is to handle the game's simulation, entity updates, and server-side calculations. The data suggests that the i9-14900K is more than sufficient for this task. The frame rates at 1080p Low, which often stress the CPU more than the GPU, are extremely high at 166.9 FPS. This indicates that the CPU is not the bottleneck even in scenarios where the GPU load is low. The processor's high single-core performance, as demonstrated by its 7040 score in Cinebench R23 single-core, is critical for a game like Rust, which relies heavily on a single main thread for many of its operations. The CPU's 97th percentile ranking against all CPUs further confirms that it is a top performer. The data points to the conclusion that the i9-14900K provides a massive performance headroom for this game, and its capabilities will not be the limiting factor in any of the measured configurations.
