Rust

The Intel Core i7-13700K paired with the AMD Radeon RX 6700 XT delivers a highly playable Rust experience at 1080p and 1440p, but the data shows a steep performance cliff at 4K. In this benchmark set, the combo ranks 923rd out of 1,717 tested combinations, placing it in the middle of the pack for this title. The measured FPS reveals a system that is clearly CPU-bound at lower resolutions, with the GPU taking over as the primary limiter only when the resolution scales up to 4K.

Resolution Scaling

The FPS drop from 1080p to 4K is dramatic and tells a clear story about where the bottleneck lies. At 1080p High settings, the combo produces 96.1 FPS average. Moving to 1440p High, that figure falls to 62.9 FPS, a reduction of roughly 35%. At 4K High, the average plummets to 35.8 FPS, which is a 63% drop from the 1080p result. This scaling pattern indicates that at 1080p, the system has enough headroom to push high frame rates, but the GPU begins to struggle as pixel count increases.

The Low settings data reinforces this interpretation. At 1080p Low, the combo hits 166.7 FPS, which is an excellent result for competitive play. At 1440p Low, it still manages 112.3 FPS, showing strong performance when graphical load is reduced. However, at 4K Low, the average drops to 67.5 FPS. This is a significant falloff — a 59% reduction from the 1080p Low figure — and it suggests that even at the lowest settings, the GPU is unable to maintain the high frame rates seen at lower resolutions.

The Ultra settings results are particularly telling. At 1080p Ultra, the combo achieves 70.9 FPS, which is still smooth. At 1440p Ultra, it drops to 51.4 FPS, and at 4K Ultra, it falls to 30.1 FPS. The 4K Ultra result is below the 30 FPS threshold often considered the minimum for playability, indicating that this combo is not suited for maxed-out 4K gaming in Rust. The scaling from 1080p to 4K at Ultra settings shows a 57% performance loss, which is consistent with the pattern seen at other quality presets.

The data suggests that the limiting component changes with resolution. At 1080p, the frame rates are high enough across all settings that the CPU is likely the primary constraint, particularly at Low where 166.7 FPS demonstrates the GPU is not saturated. As resolution increases to 4K, the GPU's workload expands significantly, and the RX 6700 XT becomes the bottleneck, as evidenced by the sharp FPS drops across all settings.

CPU Role

The Intel Core i7-13700K is a 16-core, 24-thread processor based on Raptor Lake architecture, built on a 10 nm process. It has a base clock of 3.40 GHz and a boost clock of 5.40 GHz, which are strong figures for gaming workloads. In synthetic benchmarks, the CPU scores 3,900 in Cinebench R15 multicore, 16,380 in Cinebench R20 multicore, and 39,000 in Cinebench R23 multicore. Its single-core scores are equally robust: 554 in Cinebench R15, 2,312 in R20, and 5,505 in R23.

The CPU's percentile ranking against all CPUs is 93, meaning it outperforms 93% of tested processors. Its average benchmark score is 47,282, and its nearest rivals in that metric are the Intel Core i7-13700KF (47,334, a 0.1% difference) and the AMD EPYC 4364P (47,131, a 0.3% difference). The data shows the i7-13700K is marginally behind the 13700KF but ahead of the EPYC and the Intel Core i9-12900F (47,081, a 0.4% difference).

In Rust, the CPU's high single-thread performance is likely a key factor in the strong 1080p results. The game's simulation and entity logic tend to rely on single-threaded performance, and the boost clock of 5.40 GHz provides ample headroom. The 30 MB of shared L3 cache also helps with data locality, which can be important in a game with many dynamic objects. The 16 cores and 24 threads ensure that background tasks and server-side computations do not starve the main game thread, contributing to the stable frame rates observed at 1440p and below.

The benchmark data indicates that the CPU is not the primary bottleneck at 4K, as the FPS drops are consistent with GPU limitations. At 1080p Low, the 166.7 FPS result demonstrates the CPU's ability to feed the GPU with enough data to reach high frame rates. Even at 1080p Ultra, the 70.9 FPS result is respectable, suggesting the CPU maintains its role as a capable partner to the GPU across settings.

GPU Role

The AMD Radeon RX 6700 XT is based on the Navi 22 chip with RDNA 2.0 architecture, built on a 7 nm process. It has 12 GB of GDDR6 memory on a 192-bit bus, providing 384.0 GB/s of bandwidth. The GPU's base clock is 2321 MHz, with a boost clock of 2581 MHz and a game clock of 2424 MHz. It features 2,560 shading units, 160 texture mapping units, and 64 raster operation units, along with 40 ray tracing cores.

The GPU's percentile ranking against all GPUs is 77, and its average benchmark score is 33,721. Its nearest rivals include the AMD Radeon RX 6800 (33,493, a 0.7% difference) and the NVIDIA RTX A5000 (33,294, a 1.3% difference). The RX 6700 XT is also compared to much older cards like the AMD Radeon HD 7950 (34,050, a -1% difference) and RX 480 (34,059, a -1% difference), which shows the benchmark scores are close despite generational gaps.

In Rust, the GPU's 12 GB of VRAM is sufficient for the game's textures and assets at 1440p, even at Ultra settings. The 4K Ultra result of 30.1 FPS suggests that the GPU is struggling with the higher resolution and graphical demands. The 384.0 GB/s memory bandwidth is a limiting factor at 4K, where the GPU must move significantly more data per frame. The data shows that the GPU's performance scales poorly beyond 1440p, which is consistent with a mid-range card being pushed beyond its comfortable envelope.

The GPU's clock speeds are high, with a boost of 2581 MHz, which helps at lower resolutions. At 1080p, the GPU is able to deliver 96.1 FPS at High settings, and 70.9 FPS at Ultra. However, the 4K results — 35.8 FPS at High and 30.1 FPS at Ultra — indicate that the GPU is the primary limiting component at this resolution. The 4K Low result of 67.5 FPS is notable, as it shows the GPU can still produce playable frame rates if the graphical settings are reduced significantly.

How This Combo Ranks

The combo ranks 923rd out of 1,717 tested combinations in Rust, which places it in the 54th percentile of all tested systems. This ranking reflects a balanced but not exceptional setup for this game. The CPU's 93rd percentile ranking against all CPUs is a strong point, while the GPU's 77th percentile ranking is more modest. The combination of a high-end CPU with a mid-range GPU results in a system that excels at 1080p and 1440p but falls short at 4K.

The data shows that the CPU is performing above its class, with an average benchmark score of 47,282, which is nearly identical to the 13700KF (47,334). This means the CPU is not holding back the system in any meaningful way. The GPU, with an average score of 33,721, is closer to its rivals, with the RX 6800 (33,493) being only 0.7% behind. This indicates that the GPU is the more variable component in this pairing.

In the context of Rust specifically, the 923rd rank out of 1,717 suggests that there are many combos that perform better at 4K, but the system is well above the median for 1080p and 1440p gaming. The measured FPS at 1440p High (62.9 FPS) and 1080p High (96.1 FPS) are solid results that would satisfy most players. The 4K performance, however, is the weak point, with all settings producing sub-optimal frame rates except for Low (67.5 FPS). Overall, this combo is a capable 1080p and 1440p solution, but it is not designed for 4K gaming in Rust.
