# Rust Performance Analysis: Intel Core i5-13400F + AMD Radeon RX 7600

The benchmark data for Rust reveals a combination that performs respectably at 1080p but struggles as resolution increases, with the GPU emerging as the clear bottleneck in this pairing. The combo ranks 1131 out of 1717 tested configurations, placing it in the lower-middle tier of all hardware combinations tested for this game. The Intel Core i5-13400F, with its 10 cores and 16 threads, provides solid CPU headroom, while the AMD Radeon RX 7600's 8 GB of VRAM and RDNA 3.0 architecture determine the upper limits of what this system can deliver. This analysis examines the measured FPS data across three resolutions and four quality presets, interpreting what the numbers reveal about component roles and system balance.

Resolution Scaling

The measured FPS data shows a dramatic performance drop as resolution climbs, with the scaling pattern revealing a system that is heavily GPU-limited. At 1080p with High settings, the combo delivers 81.4 FPS, which drops to 56.9 FPS at 1440p — a 30% reduction — and then plummets to 33.1 FPS at 4K, representing a 59% loss from the 1080p baseline. This steep decline indicates that the RX 7600's rendering capabilities saturate quickly as pixel count increases.

The Low preset tells a similar story with higher absolute numbers: 138.4 FPS at 1080p falls to 98.2 FPS at 1440p (a 29% drop) and then to 58.6 FPS at 4K (a 58% drop). The consistency of these percentage losses across presets suggests that resolution scaling is governed primarily by GPU fill-rate limits rather than CPU constraints. In contrast, the CPU's 3DMark scores — including a single-thread score of 960 and a max-threads score of 7307 — indicate that processor performance remains relatively stable regardless of resolution, which is typical for games that scale rendering load with pixel count.

The gap between Low and Ultra presets widens significantly at higher resolutions. At 1080p, Low produces 138.4 FPS while Ultra manages only 58 FPS — a 2.4x difference. At 4K, that gap narrows to 58.6 FPS versus 26.4 FPS — a 2.2x difference. This narrowing suggests that at 4K, the GPU is so constrained that even reducing settings cannot fully compensate for the pixel-count burden. The data implies that this combination is best suited for 1080p gaming, where the CPU can keep the GPU fed, and that 4K gaming is only viable at Low settings with frame rates barely crossing the 60 FPS threshold.

How This Combo Ranks

With a combo rank of 1131 out of 1717 tested configurations, this pairing sits in the 34th percentile of all combos tested in Rust. This places it below the median, indicating that while it can play the game, it offers a mid-tier experience relative to what other hardware combinations achieve. The ranking makes sense when examining the component-level percentiles: the CPU ranks in the 82nd percentile among all processors, while the GPU ranks in only the 63rd percentile among all graphics cards. This mismatch — a strong CPU paired with a mid-range GPU — explains why the combo's overall standing is dragged down by GPU limitations.

The CPU's nearest rivals highlight its competitive position: the Intel Core i7-13620H scores 25201 (0.1% higher), the AMD Ryzen 5 5600X3D scores 25365 (0.5% higher), and the AMD EPYC 9474F scores 25103 (0.5% lower). These negligible deltas mean the i5-13400F is effectively performance-equivalent to a wide range of processors, including both mobile and server parts, in synthetic benchmarks. For the GPU, the nearest rival is the RX 7600 XT at 20146 (0.6% higher), followed by the RX 460 at 20088 (0.8% higher) and the RTX 3070 Mobile at 20534 (1.3% lower). The close margins suggest that the RX 7600 is positioned in a crowded performance band where small architectural differences matter more than brand loyalty.

The significant gap between CPU and GPU percentiles (82 versus 63) implies that upgrading the graphics card would yield greater performance improvements in Rust than a CPU swap. The data suggests this combo's rank is primarily constrained by the GPU, and the CPU has headroom to support a more powerful graphics solution.

Settings Recommendations

The measured data points to 1080p as the sweet spot for this combination, where even Ultra settings achieve 58 FPS. For players prioritizing smoothness, Low settings at 1080p deliver 138.4 FPS, which is more than double the Ultra frame rate and ideal for competitive play. Medium settings at 94.2 FPS offer a balanced experience that maintains visual quality while keeping frame rates well above refresh-rate thresholds.

At 1440p, the recommended approach is Medium settings, which produce 61.6 FPS — the only preset at this resolution that exceeds 60 FPS. High settings at 56.9 FPS are borderline, and Ultra at 43.3 FPS drops below comfortable playability for fast-paced survival gameplay. The data suggests that players with 1440p monitors should accept Medium quality as the practical ceiling.

For 4K, the situation is more constrained. Low settings yield 58.6 FPS, which is playable but requires significant visual compromises. Medium drops to 39.8 FPS, High to 33.1 FPS, and Ultra to 26.4 FPS — all below the smoothness threshold. The data implies that 4K gaming with this combo is only viable at Low settings, and even then, frame rates hover near 60 FPS rather than exceeding it. The best overall experience per the measured rows is 1080p Medium or High, balancing visual fidelity with frame rates between 81.4 and 94.2 FPS.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest performance across all presets. Low settings produce an average of 138.4 FPS, Medium achieves 94.2 FPS, High reaches 81.4 FPS, and Ultra bottoms out at 58 FPS. The progression from Low to Ultra shows a 58% performance penalty for maximum quality, which is substantial but leaves even the most demanding preset playable.

Moving to 2560x1440, the FPS figures drop noticeably. Low settings average 98.2 FPS — still excellent — while Medium hits 61.6 FPS and High manages 56.9 FPS. Ultra falls to 43.3 FPS, which is below the 60 FPS target for smooth gameplay. The delta between Low and Ultra at this resolution is 56%, slightly narrower than at 1080p, indicating the GPU is beginning to saturate.

At 3840x2160, performance degrades significantly. Low settings average 58.6 FPS, barely crossing the playability threshold, while Medium drops to 39.8 FPS and High to 33.1 FPS. Ultra produces just 26.4 FPS, making it unsuitable for anything but static scenes. The Low-to-Ultra gap narrows to 55%, showing that even reducing settings cannot overcome the pixel-count burden at 4K. The data reveals a consistent pattern: this system is optimized for 1080p, capable at 1440p with compromises, and only marginally playable at 4K.

CPU Role

The Intel Core i5-13400F brings 10 cores and 16 threads, with a base clock of 2.50 GHz and a boost clock of 4.60 GHz. Its 20 MB of shared L3 cache and 1.25 MB per-core L2 cache provide the memory hierarchy needed for game logic and entity management in a survival game like Rust, which often involves complex world simulations and many simultaneous actors.

The CPU's synthetic benchmark results show a strong multi-threaded performer: Cinebench R23 multicore scores 21279, while single-core scores 3004. Geekbench results show 10971 multicore and 2301 single-core. The 3DMark tests reveal scaling from 1880 at 2 threads to 7314 at 16 threads, indicating efficient thread utilization across all cores. The PassMark multi-thread score of 25032 and single-thread score of 3634 confirm balanced performance.

The percentile ranking of 82% versus all CPUs indicates this processor outperforms the majority of alternatives, and its nearest rivals — the i7-13620H (0.1% higher), Ryzen 5 5600X3D (0.5% higher), and EPYC 9474F (0.5% lower) — show it trades blows with diverse competitors. Given the GPU-limited nature of the measured FPS data, the CPU's role appears to be providing ample headroom that is not fully utilized in Rust at higher resolutions. The 65W TDP suggests efficient operation, and the LGA 1700 socket with DDR4/DDR5 support offers memory flexibility.

GPU Role

The AMD Radeon RX 7600 is built on the RDNA 3.0 architecture with the Navi 33 chip, fabricated on TSMC's 6 nm process. Its 13,300 million transistors and 204 mm² die size pack 2048 shading units, 128 TMUs, and 64 ROPs, with 32 ray-tracing cores. The GPU operates at a base clock of 1720 MHz, boosts to 2655 MHz, and has a game clock of 2250 MHz.

Memory configuration consists of 8 GB of GDDR6 on a 128-bit bus, providing 288.0 GB/s of bandwidth. The 165W TDP and dual-slot design with a single 8-pin connector make it a moderate-power card, with a suggested PSU of 450W. The PCIe 4.0 x8 interface and DisplayPort 2.1 outputs support modern display connectivity.

The GPU's benchmark performance shows a PassMark G3D score of 16634 and a 3DMark Steel Nomad DX12 score of 2310. Its 63rd percentile ranking places it below the CPU's percentile, confirming the GPU as the system's performance limiter. The nearest rivals — RX 7600 XT (0.6% higher), RX 460 (0.8% higher), and RTX 3070 Mobile (1.3% lower) — demonstrate that the RX 7600 sits in a highly competitive performance tier where small margins separate products.

The measured FPS data strongly implicates the GPU as the bottleneck: the consistent 30% FPS drops from 1080p to 1440p and the inability to maintain 60 FPS at 4K on any preset except Low point to fill-rate and bandwidth limitations. The 288.0 GB/s bandwidth and 8 GB VRAM appear insufficient for high-detail 4K rendering, while at 1080p, the GPU has enough headroom to deliver playable frame rates across all settings. The data suggests that the RX 7600 is best matched with 1080p displays, and that its 63rd percentile ranking accurately reflects its mid-range positioning.
