Rust

The Intel Core i7-13700K paired with the AMD Radeon RX 6600 delivers a highly resolution-dependent experience in Rust. At 1080p, the combination is clearly capable, posting an average of 128.5 FPS on Low settings and 73.4 FPS on High. The data shows a sharp drop-off at 1440p, where only the Low preset manages to stay above the 60 FPS threshold, achieving 87.4 FPS. At 4K, the system struggles across the board, with the best result being 52.4 FPS on Low, which falls short of the playable threshold. The measured FPS values reveal that this configuration is best suited for 1080p gaming, with 1440p viable only at the lowest graphical preset.

Measured FPS Breakdown

At 1920x1080, the frame rates are competitive and smooth. The Low preset delivers an average of 128.5 FPS, providing a significant headroom above the 60 FPS playable threshold. Stepping up to Medium yields 82.7 FPS, still comfortably playable. High settings produce 73.4 FPS, which remains fluid for most gameplay scenarios. Ultra is the only preset at this resolution that dips below the threshold, averaging 56.1 FPS. The scaling from Low to Ultra shows a performance cost of roughly 56% of the frame rate, indicating that the GPU is handling the increased load but hits a ceiling at the highest settings.

Moving to 2560x1440, the performance picture changes considerably. Low settings deliver 87.4 FPS, which is the only preset here that clears the 60 FPS bar. Medium drops to 58.4 FPS, just shy of playable, while High falls to 47.3 FPS. Ultra is the most demanding, averaging only 34.4 FPS. The gap between Low and Medium is substantial, a drop of 29 FPS, suggesting that the GPU’s memory bandwidth and compute resources are strained by the additional pixel count and texture detail at this resolution.

At 3840x2160, the combination is not viable for smooth play. Low settings produce 52.4 FPS, the highest result at 4K, but still below the playable threshold. Medium and High are nearly identical, at 32.1 FPS and 31.5 FPS respectively, showing that the GPU is severely bottlenecked. Ultra settings bottom out at 21.6 FPS, which is borderline unplayable. The data indicates that the RX 6600’s 8 GB of GDDR6 memory and 224.0 GB/s bandwidth are insufficient for 4K rendering in Rust, regardless of the CPU’s capabilities.

CPU and GPU Roles

The benchmark results indicate that the GPU is the primary limiting factor at higher resolutions, while the CPU provides ample headroom at 1080p. The Intel Core i7-13700K, with its 16 cores and 24 threads, is a high-end processor that ranks in the 89th percentile of all CPUs. Its multi-threaded performance, evidenced by a Cinebench R23 multicore score of 30745, ensures that it is not the bottleneck in most gaming scenarios. At 1080p, the scaling from Low to Ultra shows a drop from 128.5 FPS to 56.1 FPS, which is a GPU-driven decline, as the CPU is capable of feeding the GPU at these lower resolutions.

When moving from 1080p to 1440p, the average FPS on Low settings drops from 128.5 to 87.4, a 32% reduction. This scaling is primarily due to the GPU’s fill rate and memory bandwidth being taxed by the higher pixel count. The RX 6600’s pixel rate of 159.4 GPixel/s and texture rate of 279.0 GTexel/s are moderate for a mid-range card, and the 128-bit memory bus becomes a constraint at 1440p. At 4K, the GPU is clearly overwhelmed, with all presets falling below 60 FPS, confirming that the RX 6600 is the limiting component.

The CPU’s role becomes more apparent at lower resolutions and settings. At 1080p Low, the system achieves 128.5 FPS, which is likely close to the CPU’s single-thread limit in Rust, given the game’s known CPU sensitivity in certain scenarios. However, the i7-13700K’s strong single-core performance, with a Geekbench single-core score of 2529, ensures that it can handle the game’s logic and physics calculations without dragging down the average frame rate. The data suggests that for this pairing, the GPU dictates performance at 1440p and 4K, while the CPU is sufficient to avoid becoming a bottleneck at 1080p.

Best Settings per Resolution

At 1920x1080, the best settings that maintain an average of at least 60 FPS are High, which delivers 73.4 FPS. This preset offers a good balance between visual fidelity and performance, allowing for smooth gameplay without compromising too much on detail. The Medium preset also clears the threshold at 82.7 FPS, but High provides a richer visual experience while still staying above 60 FPS. Ultra is not recommended here, as it falls to 56.1 FPS, below the playable threshold.

For 2560x1440, the only viable option is the Low preset, which achieves 87.4 FPS. This is the most demanding setting that stays at or above 60 FPS, but it requires a significant reduction in graphical quality. Medium settings at 58.4 FPS are just below the threshold, so users must accept lower detail levels to maintain smooth frame rates at this resolution. The data shows that the RX 6600 cannot handle higher presets at 1440p without dropping below the playable mark.

At 3840x2160, no preset meets the 60 FPS requirement. The best result is 52.4 FPS on Low, which is still below the playable threshold. This means that 4K gaming is not recommended with this hardware combination, as even the lowest settings fail to deliver a smooth experience. Users would need to reduce the resolution or upgrade the GPU to achieve playable frame rates at 4K.

Similar Performance Alternatives

Looking at the nearest rivals for the CPU, the Intel Core i7-13700K has an average benchmark score of 46881. The AMD Ryzen 9 5900 is nearly identical, with a score of 46971, representing a 0.2% difference. The AMD Ryzen AI 9 HX PRO 375 is also close at 47022, just 0.3% ahead. On the other side, the AMD Ryzen 9 7845HX and Intel Xeon w3-2535 both score 46654 and 46653, respectively, which are 0.5% behind. In gaming, these CPUs would perform similarly, meaning that swapping the i7-13700K for any of these alternatives would likely yield negligible FPS differences in Rust, provided the GPU remains the same.

For the GPU, the AMD Radeon RX 6600 has an average benchmark score of 19036. Its nearest rival, the NVIDIA Quadro K6000, scores 19030, a 0% difference, indicating nearly identical performance. The NVIDIA GeForce RTX 4050 Mobile is slightly ahead at 19049, a 0.1% delta, while the NVIDIA Tesla K20m scores 19089, which is 0.3% higher. The NVIDIA RTX 2000 Ada Generation is 0.4% behind at 18954. In real-world gaming, these GPUs would produce very similar frame rates in Rust, so users with any of these cards can expect comparable results to the RX 6600 at the same settings and resolutions.

The Verdict

The data clearly indicates that this PC can run Rust, but the playable experience is heavily dependent on resolution. At 1920x1080, the system is fully capable, with High settings delivering 73.4 FPS, and Low and Medium also clearing the 60 FPS threshold at 128.5 FPS and 82.7 FPS, respectively. This makes 1080p the sweet spot for this combination, offering smooth gameplay across most presets.

At 2560x1440, the system is only playable on Low settings, achieving 87.4 FPS. This is a viable option for users who prioritize frame rate over visual quality, but it limits the experience. Medium settings at 58.4 FPS are just below the playable threshold, so users must accept a compromise. At 3840x2160, the system fails to reach 60 FPS on any preset, with the best result being 52.4 FPS on Low. This means 4K gaming is not feasible with this hardware, and users should avoid attempting it.

Overall, the verdict is that this PC handles Rust well at 1080p, marginally at 1440p with reduced settings, and not at all at 4K. The Intel Core i7-13700K provides sufficient CPU power, but the AMD Radeon RX 6600 is the limiting factor at higher resolutions, particularly due to its 8 GB memory capacity and 128-bit bus width.

How This Combo Ranks

In the database of tested combinations, this pairing of the Intel Core i7-13700K and AMD Radeon RX 6600 ranks 2884 out of 3723 combos for Rust. This places it in the lower portion of the rankings, around the 22nd percentile, indicating that while it is not among the worst performers, it is far from the top. The ranking reflects the GPU’s mid-range positioning, as the CPU is a high-end part that could support a more powerful graphics card. The data suggests that users with this combination are likely playing at 1080p, where the performance is adequate, but the system’s overall standing is dragged down by its limitations at higher resolutions. For those seeking better performance, upgrading the GPU would yield a more significant improvement than changing the CPU, given the current bottleneck.
