# Rust with Intel Core i5-13400F + AMD Radeon RX 9070 XT

The data for this combo in Rust shows a system that is heavily GPU-limited at higher resolutions, with the AMD Radeon RX 9070 XT carrying the load while the Intel Core i5-13400F provides sufficient headroom for high refresh rates at 1080p. Across the twelve measured configurations, the average frame rates range from a low of 41.4 FPS at 4K Ultra to a high of 214.9 FPS at 1080p Low, demonstrating a wide performance envelope that scales predictably with both resolution and graphics settings.

Resolution Scaling

The resolution scaling behavior of this combo in Rust reveals a classic GPU-bound scenario. Moving from 1920x1080 to 2560x1440 at High settings, the average frame rate drops from 127.9 FPS to 88.6 FPS, a reduction of approximately 30.7%. The scaling continues at 3840x2160, where the same High preset yields 49.5 FPS, representing a further 44.1% decrease from the 1440p result. This steep drop-off pattern indicates that the RX 9070 XT is the primary limiting component as pixel count increases.

The settings sensitivity amplifies at higher resolutions. At 4K, the gap between Low and Ultra settings is substantial: 93.8 FPS versus 41.4 FPS, a difference of 52.4 FPS. This spread widens compared to 1440p, where Low achieves 152.6 FPS and Ultra reaches 67.5 FPS, a gap of 85.1 FPS. The data suggests that at 4K, the GPU's rendering pipeline becomes saturated quickly as visual complexity increases, with each preset tier exacting a significant toll on frame rate.

At 1080p, the scaling pattern changes character. The difference between Low (214.9 FPS) and High (127.9 FPS) is 87 FPS, and Ultra sits at 96.6 FPS. The relative drop from Low to Ultra at 1080p is approximately 55%, which is less severe than the 55.9% drop at 4K (from 93.8 to 41.4 FPS). This indicates that at 1080p, the CPU can still feed the GPU adequately, but the GPU's workload per frame becomes the dominant constraint even at lower pixel counts. The 1440p results occupy a middle ground, with frame rates that suggest a balanced but increasingly GPU-limited system as settings rise.

CPU Role

The Intel Core i5-13400F brings a 10-core, 16-thread configuration based on Raptor Lake architecture, with a base clock of 2.50 GHz and a boost clock of 4.60 GHz. The processor's benchmark profile shows strong multi-threaded performance, with a Cinebench R23 multicore score of 21279 and a single-core score of 3004. In Rust, which is known for its server-side simulation and complex world interactions, this CPU provides adequate compute headroom, as evidenced by the frame rates achieved at lower resolutions.

The 13400F's performance relative to its nearest rivals places it in a tightly contested mid-range tier. Its average benchmark score of 25236 sits within 0.5% of the AMD Ryzen 5 5600X3D (25365) and within 0.1% of the Intel Core i7-13620H (25201). The deltaPct values show a performance spread of less than 1% across all four nearest rivals, indicating that the CPU's compute capability is well within the expected range for its class.

The 20 MB of shared L3 cache and dual-channel memory support (DDR4 and DDR5) contribute to the CPU's ability to handle Rust's unoptimized code paths, which often rely on single-thread performance. The single-thread benchmarks — 960 in 3DMark single-thread and 3634 in PassMark single-thread — suggest that the 4.60 GHz boost clock is effective for gaming workloads. However, the data shows that at 1080p Low, the system reaches 214.9 FPS, which indicates the CPU is not the bottleneck at this resolution; rather, the GPU's capabilities set the ceiling.

GPU Role

The AMD Radeon RX 9070 XT is the dominant component in this pairing, featuring 16 GB of GDDR6 memory on a 256-bit bus with 644.6 GB/s of bandwidth. The GPU's RDNA 4.0 architecture, built on a 4 nm process at TSMC, includes 4096 shading units and 128 ROPs, with a boost clock of 2970 MHz and a game clock of 2400 MHz. The passmark G3D score of 26795 places it in the 82nd percentile among all GPUs, and its average benchmark score of 39647 is within 0.6% of its nearest rivals, including the AMD Radeon Pro 575 (39703) and the NVIDIA RTX A500 Mobile (39568).

The GPU's frame rate delivery in Rust shows a clear correlation between memory bandwidth and performance at high settings. At 4K Ultra, the system produces 41.4 FPS, which aligns with the GPU's compute limits when handling heavy draw calls and texture streaming. The 16 GB VRAM capacity is likely sufficient for Rust's large world maps, but the 644.6 GB/s bandwidth becomes a constraint at 4K, where texture fetch demands increase exponentially.

The RX 9070 XT's compute capabilities, measured at 48.66 TFLOPS FP32, provide the raw throughput needed for Rust's shading and post-processing effects. The transition from Medium to High at 4K (62.6 to 49.5 FPS) shows a 21% performance cost, while the jump from High to Ultra (49.5 to 41.4 FPS) costs an additional 16.4%. These diminishing returns suggest that the GPU's pixel fill rate and texture units — 380.2 GPixel/s and 760.3 GTexel/s respectively — are the limiting factors at extreme settings.

FAQ

Q: What is the highest average frame rate this combo achieves in Rust?

A: The highest measured average frame rate is 214.9 FPS at 1920x1080 with Low settings. This drops to 152.9 FPS at Medium, 127.9 FPS at High, and 96.6 FPS at Ultra for the same resolution.

Q: How does this combo perform at 4K with Ultra settings?

A: At 3840x2160 with Ultra settings, the combo produces an average of 41.4 FPS. This is the lowest measured result across all configurations, indicating that 4K Ultra is beyond the comfortable range for this pairing.

Q: Is the CPU or GPU the bottleneck at 1440p High settings?

A: At 2560x1440 High, the system averages 88.6 FPS. Given that the CPU's single-thread performance is sufficient to drive 214.9 FPS at 1080p Low, the GPU is the limiting factor at 1440p High, as the workload shifts towards pixel processing.

Q: What is the performance difference between Low and Ultra at 1080p?

A: At 1920x1080, Low settings achieve 214.9 FPS while Ultra settings achieve 96.6 FPS. This represents a 55% reduction in frame rate when moving from the lowest to the highest preset.

Q: How does this combo's frame rate scale from 1440p to 4K at Medium settings?

A: At 2560x1440 Medium, the average is 102.8 FPS. At 3840x2160 Medium, it drops to 62.6 FPS, a 39.1% reduction. This scaling indicates that the GPU's memory bandwidth and compute resources are increasingly strained at 4K.

Q: What rank does this combo hold among all tested combinations in Rust?

A: The combo ranks 399 out of 1717 tested combinations, placing it in the top 23.2% of all systems tested in this game.

How This Combo Ranks

The Intel Core i5-13400F and AMD Radeon RX 9070 XT combination ranks 399th out of 1717 tested combos in Rust, placing it in the upper quartile of systems. This ranking reflects the strong GPU performance, as the RX 9070 XT's 82nd percentile standing among all GPUs is the primary driver of the combo's position. The CPU's 82nd percentile ranking among all processors contributes complementary support, ensuring that the GPU is not starved of data.

The 399th rank indicates that while this system is capable of high frame rates at 1080p and playable performance at 1440p, there are 398 combos that achieve better overall results in Rust. These higher-ranked systems likely feature more powerful GPUs or CPUs, given that Rust's performance scales with both components depending on resolution and settings. The data shows that this combo excels at 1080p, where it achieves frame rates above 96 FPS across all settings, but falls below 60 FPS at 4K Ultra, which limits its standing in the overall rankings.

In the context of the combo's position, the measured frame rates at 1440p High (88.6 FPS) and 4K High (49.5 FPS) represent the practical boundaries for this pairing. The rank of 399 suggests that users seeking higher 4K performance would need to consider alternatives, while those targeting 1080p or 1440p gaming will find this combo well-suited, as the data indicates consistent performance above 60 FPS at 1440p across Low, Medium, and High settings.
