Rust

The Intel Core i7-13700K paired with the NVIDIA GeForce RTX 4070 SUPER delivers a robust Rust experience, but the data reveals a clear split between CPU-bound and GPU-bound scenarios. At 1080p, the combo is heavily CPU-limited, producing frame rates that far exceed the GPU’s rendering ceiling at higher resolutions. Conversely, at 4K, the GPU becomes the primary constraint, with frame rates dropping to levels that approach the edge of playability on the highest settings. This is a system that can handle Rust at competitive speeds on lower settings, but demands careful tuning for 4K Ultra play.

Resolution Scaling

The measured FPS data shows a predictable, yet steep, performance curve as resolution increases. At 1920x1080 with Low settings, the combo achieves an average of 250.9 FPS, which drops to 170.5 FPS at 2560x1440, and further to 103.4 FPS at 3840x2160. This represents a 58.8% drop from 1080p to 4K at Low settings, indicating that the CPU is capable of feeding frames far faster than the GPU can render at higher pixel counts. The scaling is more severe at higher settings: at Ultra, the average FPS falls from 110.8 at 1080p to 76.6 at 1440p, and finally to 43.6 at 4K—a 60.6% decrease.

This pattern strongly suggests that at 1080p, the Intel Core i7-13700K’s 16 cores and 24 threads are the limiting factor, as the GPU is not fully saturated. At 4K, the RTX 4070 SUPER’s 12 GB of GDDR6X memory and 504.2 GB/s bandwidth become the bottleneck, especially on Ultra settings where the pixel workload quadruples. The gap between Low and Ultra settings at 4K is 59.8 FPS (103.4 vs 43.6), which is nearly identical to the gap at 1080p (140.1 FPS), confirming that the GPU’s rendering capacity is the dominant variable at high resolutions.

How This Combo Ranks

In the overall benchmark database, this specific CPU-GPU combination ranks 212 out of 1717 tested combos for Rust, placing it in the top 12.3% of all systems tested. This rank reflects a strong balance between the i7-13700K’s high single-thread performance and the RTX 4070 SUPER’s robust rasterization capabilities. The CPU itself sits in the 93rd percentile among all CPUs, while the GPU is in the 84th percentile, so the combo outperforms its individual component percentiles would suggest, indicating a well-matched pairing for this title.

When compared to the nearest rival combos, the i7-13700K’s closest competitor is the Intel Core i7-13700KF, which scores a near-identical average of 47334 (a delta of -0.1%). This is expected, as the KF variant lacks integrated graphics but otherwise shares the same architecture. The AMD EPYC 4364P is 0.3% faster, and the Intel Core i9-12900F is 0.4% faster, while the AMD Ryzen 9 PRO 5945 is 0.5% slower. These tiny deltas suggest that in Rust, the CPU choice matters less than the GPU, as the game’s engine appears to be more sensitive to raw clock speeds than core counts.

GPU Role

The NVIDIA GeForce RTX 4070 SUPER is built on the AD104 chip with 7168 shading units and 224 tensor cores, operating at a boost clock of 2475 MHz. Its 12 GB of GDDR6X memory on a 192-bit bus provides 504.2 GB/s of bandwidth, which is ample for Rust’s relatively modest texture requirements. The GPU’s 56 RT cores and 80 ROPs contribute to its 198.0 GPixel/s pixel rate, which becomes critical at 4K Ultra where the pixel fill rate is stressed.

The data shows the GPU’s impact most clearly at 4K: from Low to Ultra settings, the average FPS drops from 103.4 to 43.6, a 57.8% reduction. This is a steeper decline than at 1080p (from 250.9 to 110.8, a 55.8% drop), confirming that the GPU is the primary bottleneck at 4K. The RTX 4070 SUPER’s 35.48 TFLOPS FP32 performance is sufficient for High settings at 1440p (99.2 FPS) and even 4K High (57.4 FPS), but Ultra settings push it to the limit. The GPU’s passmark G3D score of 29995 and 3DMark Steel Nomad score of 4627 place it in the 84th percentile, which aligns with its measured performance in Rust.

Measured FPS Breakdown

At 1920x1080, the combo delivers excellent frame rates across all settings. Low settings produce an average of 250.9 FPS, which is ideal for high-refresh-rate monitors. Medium settings yield 168.3 FPS, High settings 143.4 FPS, and Ultra settings 110.8 FPS. The difference between Low and Ultra is 140.1 FPS, indicating that the CPU can maintain high frame rates even when the GPU is not fully loaded.

Moving to 2560x1440, the GPU begins to exert more influence. Low settings average 170.5 FPS, Medium 117.8 FPS, High 99.2 FPS, and Ultra 76.6 FPS. The scaling from 1080p to 1440p is roughly 32% for Low settings and 30.9% for Ultra settings, showing a consistent performance penalty as pixel count increases. At 3840x2160, the frame rates become more demanding: Low averages 103.4 FPS, Medium 67.9 FPS, High 57.4 FPS, and Ultra 43.6 FPS. The Ultra setting at 4K is the only configuration that falls below 60 FPS, which is the threshold for smooth gameplay on most displays.

The data indicates that for competitive play, 1080p Low or Medium settings are optimal, while 1440p High offers a good balance of visual fidelity and performance. At 4K, users should stick to Low or Medium settings to maintain playable frame rates, as High and Ultra dip below 60 FPS.

CPU Role

The Intel Core i7-13700K is a 16-core, 24-thread processor based on the Raptor Lake architecture, with a base clock of 3.40 GHz and a boost clock of 5.40 GHz. Its 30 MB of shared L3 cache and 2 MB per-core L2 cache provide ample bandwidth for Rust’s simulation and entity updates. The CPU’s single-thread performance is exceptional, as evidenced by its 3DMark single-thread score of 1136 and Cinebench R23 single-core score of 5505, which place it in the 93rd percentile among all CPUs.

In Rust, the CPU’s role is most apparent at 1080p Low settings, where the average FPS of 250.9 is far above what the GPU can sustain at higher resolutions. This suggests that the i7-13700K’s high boost clock is capable of feeding the GPU faster than it can render, making the CPU the bottleneck in this scenario. However, as resolution increases, the GPU takes over as the limiting factor, and the CPU’s performance headroom becomes less relevant. The CPU’s multi-threaded performance, reflected in its Cinebench R23 multicore score of 39000, ensures that background tasks and game logic do not cause frame drops, even in busy server environments.

The CPU’s nearest rivals show minimal performance deltas (ranging from -0.5% to +0.4%), indicating that the i7-13700K is well-positioned in its class. For Rust specifically, the CPU’s 5.40 GHz boost clock is more valuable than its core count, as the game’s main thread is heavily single-threaded. This is why the i7-13700K performs nearly identically to the i7-13700KF and i9-12900F in synthetic benchmarks, with all three falling within 0.4% of each other.

FAQ
