Rust

The Intel Core i5-13400F paired with the AMD Radeon RX 9070 delivers a robust 1080p gaming experience in Rust, but the data reveals a clear CPU bottleneck at lower resolutions that shifts to a GPU limitation as resolution increases. The combination ranks in the 500th position out of 1717 tested combos, placing it in the upper 29% of all systems tested for this title.

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

The Intel Core i5-13400F is a 10-core, 16-thread processor from the Raptor Lake architecture, built on Intel's 10 nm process node. It operates with a base clock of 2.50 GHz and a boost clock of 4.60 GHz, with a thermal design power of 65 W. The processor features an L3 cache of 20 MB shared across cores, with L1 cache at 80 KB per core and L2 at 1.25 MB per core. This configuration supports both DDR4 and DDR5 memory through a dual-channel memory bus, and connectivity includes PCIe Gen 5 with 16 lanes available to the CPU.

Benchmark results for this CPU show strong multi-threaded performance, with a Cinebench R23 multicore score of 21279 and a single-core score of 3004. The Passmark multithread score reaches 25032, while single-thread performance registers 3634. The processor achieves a 3DMark 16-thread score of 7314 and a max-thread score of 7307, indicating consistent scaling across thread counts. The Geekbench multicore score of 10971 and single-core score of 2301 reinforce this pattern.

The data indicates that this CPU sits at the 82nd percentile against all CPUs, with an average benchmark score of 25236. Its nearest rivals include the Intel Core i7-13620H with a delta of 0.1% and the AMD Ryzen 5 5600X3D with a delta of -0.5%, showing that this processor performs essentially on par with those alternatives in synthetic benchmarks.

In Rust specifically, the CPU's role becomes apparent when examining the FPS scaling across resolutions. At 1080p with Low settings, the system achieves 209.8 FPS average, which drops to 148.9 FPS at 1440p and 85.5 FPS at 4K. This steep decline as resolution increases suggests that at 1080p, the CPU is capable of feeding frames faster than the GPU can render them, but the GPU becomes the limiting factor as pixel count rises.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the Intel Core i5-13400F and AMD Radeon RX 9070 achieves a rank of 500 out of 1717 tested combos in Rust, placing it in the top 29% of all systems evaluated. This ranking reflects a competitive position that allows for smooth gameplay at most settings, though it does not place the system among the absolute top performers.

The CPU's average benchmark score of 25236 places it within a tight cluster of rivals, with the Intel Core i7-13620H at 25201 (0.1% delta) and the AMD Ryzen 5 5600X3D at 25365 (-0.5% delta). This performance parity means the CPU choice is unlikely to be the differentiator between these systems in Rust.

The GPU, meanwhile, holds a 79th percentile ranking against all GPUs with an average benchmark score of 34780. Its nearest rivals include the NVIDIA A2 at 34866 (-0.2% delta) and the NVIDIA Quadro GV100 at 34677 (0.3% delta). The RX 9070's position in the GPU hierarchy contributes significantly to the overall combo ranking, as the measured FPS data shows it can drive high frame rates at lower resolutions when the CPU keeps up.

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

The measured FPS data reveals a consistent pattern of performance degradation as resolution increases, but the magnitude of the drop varies significantly by settings preset. At Low settings, the system delivers 209.8 FPS at 1080p, which falls to 148.9 FPS at 1440p (a 29% reduction) and further to 85.5 FPS at 4K (a 59% reduction from 1080p). This scaling suggests that at Low settings, the CPU can maintain high frame rates, and the GPU becomes increasingly stressed as resolution grows.

At High settings, the frame rate drops from 120.8 FPS at 1080p to 81.8 FPS at 1440p (a 32% reduction) and then to 52.1 FPS at 4K (a 57% reduction from 1080p). The Ultra preset shows a similar pattern, with 91.7 FPS at 1080p, 61.6 FPS at 1440p, and 38.9 FPS at 4K. This consistent scaling across presets indicates that the GPU is the primary bottleneck at higher resolutions, while the CPU's influence is more pronounced at 1080p where frame rates exceed what the GPU can render.

The Medium settings preset shows the smallest relative drop between 1440p and 4K, moving from 97.7 FPS to 57.2 FPS. This suggests that Medium settings strike a balance where neither component is severely overburdened, though the GPU still handles the increased pixel workload at 4K.

FAQ — 4-6 Q&A pairs answerable from FACT PACK data

Q: What is the best resolution for playing Rust with this combo at High settings?

A: At High settings, the system achieves 120.8 FPS at 1080p, 81.8 FPS at 1440p, and 52.1 FPS at 4K. The 1440p resolution offers a strong balance, providing a 32% frame rate reduction from 1080p while still maintaining smooth gameplay above 60 FPS.

Q: How does the CPU compare to its nearest rival in synthetic benchmarks?

A: The Intel Core i5-13400F has an average benchmark score of 25236, which is 0.1% higher than the Intel Core i7-13620H at 25201 and 0.5% higher than the AMD Ryzen 5 5600X3D at 25365. This places the CPU in a virtual tie with these alternatives.

Q: What is the highest frame rate achievable with this combo at 1080p?

A: The highest measured frame rate at 1080p is 209.8 FPS average, achieved with the Low settings preset. The Medium preset delivers 141.3 FPS, while High reaches 120.8 FPS and Ultra drops to 91.7 FPS.

A: The AMD Radeon RX 9070 ranks in the 79th percentile against all GPUs, with an average benchmark score of 34780. Its closest rival, the NVIDIA A2, scores 34866, representing a 0.2% delta.

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

The AMD Radeon RX 9070 is built on the RDNA 4.0 architecture using a 4 nm process at TSMC, featuring the Navi 48 chip. It carries 16 GB of GDDR6 memory on a 256-bit bus, providing a bandwidth of 644.6 GB/s. The GPU operates with a base clock of 1330 MHz and a boost clock of 2520 MHz, with a game clock rated at 2070 MHz and memory clock at 2518 MHz (20.1 Gbps effective). The card includes 3584 shading units, 224 texture mapping units, 128 render output units, and 56 ray tracing cores, delivering 36.13 TFLOPS of FP32 performance.

In synthetic benchmarks, the RX 9070 achieves a 3DMark Steel Nomad DX12 score of 6290, a Geekbench OpenCL score of 133741, and a Geekbench Vulkan score of 165532. The Passmark G3D score reaches 25381, with a GPU compute score of 14737. The GPU's average benchmark score of 34780 places it in the 79th percentile against all GPUs, with nearest rivals including the NVIDIA A2 at 34866 and the NVIDIA Quadro GV100 at 34677.

The GPU's role in Rust becomes evident when examining the FPS data at different settings. At 1080p, the GPU allows the CPU to push frame rates well above 200 FPS on Low settings, but at 4K, even the Low preset only yields 85.5 FPS. This indicates that the 16 GB VRAM and high bandwidth are sufficient for Rust's demands, but the raw rendering throughput becomes the constraint at higher resolutions.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS data, the Medium settings preset at 1440p offers the most balanced experience for this combo. At 1440p Medium, the system achieves 97.7 FPS average, which is comfortably above 60 FPS and provides a significant visual improvement over Low settings while maintaining smooth performance. The 1080p Medium result of 141.3 FPS also provides an excellent experience for users prioritizing frame rate, with a 17% improvement over High settings at the same resolution.

For users with 4K displays, the Low settings preset is the only viable option, delivering 85.5 FPS average. The Medium preset at 4K drops to 57.2 FPS, while High falls to 52.1 FPS and Ultra to 38.9 FPS, making these presets less suitable for smooth gameplay. At 1080p, the High preset delivers 120.8 FPS, which is sufficient for most gaming scenarios and offers better visual fidelity than Medium without a substantial frame rate penalty.

The Ultra preset is only recommended for 1080p gaming, where it achieves 91.7 FPS. At 1440p, Ultra drops to 61.6 FPS, which may be acceptable for some users, but the 4K Ultra result of 38.9 FPS falls below playable thresholds for most gamers.
