The CPU is a 6-core, 12-thread desktop processor from the 8000 series, built on 4 nm Zen 4 (Phoenix) architecture with a base clock of 4.20 GHz and a boost of 4.70 GHz. The GPU, a Radeon RX 6700 XT with 12 GB of GDDR6 memory on a 192-bit bus, uses the RDNA 2.0 architecture (Navi 22) with a game clock of 2424 MHz and boost 2581 MHz. This pair’s measured results in Rust range from an average of 29 FPS at 4K Ultra to 165 FPS at 1080p Low, and the combined system ranks 1946th out of 3723 tested combos in this game, placing it just below the middle of the dataset.

FAQ

Q: What average frame rate can I expect at 1920×1080 in Rust?

A: The measured average FPS varies by preset: 165 at Low, 114 at Medium (with min 94 and max 127), 93 at High, and 71 at Ultra. The non-precise numbers are from the same official dataset, so 1440p also shows a range from 114 at Low down to 49 at Ultra.

Q: How does the combination's overall rank compare to the CPU and GPU percentiles?

A: The combo ranks 1946 of 3723. The CPU sits at the 77th percentile of all CPUs with an average benchmark score of 25005; the GPU lands at the 72nd percentile with an average of 27425. The mid-pack rank in Rust suggests the two components don't reach the same percentile level in this specific title.

Q: Are there any documented minimum frame times?

A: Only the Medium preset provides min and max values: 1080p gives an average of 114 with min 94 and max 127; 1440p runs at 76 average (min 65, max 88); 4K Medium shows 45 average (min 38, max 52). No other settings include lower/upper bounds.

Q: What is the CPU's single-thread and multi-thread performance relative to its average?

A: The CPU’s Cinebench R23 multi-core score is 20891, while the single-core score is 2943. Its 3DMark results include 6165 in max-thread and 951 in single-thread, reflecting a CPU with balanced 6-core, 12-thread or 24-thread, and a single-thread index that rivals.

Q: What memory specification does the 8400F support, and how does that contour the pairing?

A: It supports dual-channel DDR5 with a maximum memory bandwidth of 83.2 GB/s. The GPU is GDDR6 with 12 GB of VRAM as a 192-bit interface. These two independent memory systems are both configured for the game.

Q: Which quality preset gives the smoothest result at 1440p?

A: From the measured data, Low yields 114 FPS, Medium 76 FPS, High 64 FPS, and Ultra 49 FPS. For sustained higher visual quality, Medium is the only 1440p preset with min/max data (65–88) and remains above the 60 FPS threshold.

How This Combo Ranks

The rank of 1946 in 3723 is the only game-specific number provided. That position puts the Ryzen 5 8400F – RX 6700 XT pairing in the mid-portion of the tested pool, not at the platform peak. To frame this in component terms, the CPU’s standard score of 25005 puts it at the 77th percentile of all processors. Its immediate vendors are listed as the AMD Ryzen 5 7500F with an average score of 24964 and a delta of +0.2%, the Intel Core i7-11850H at 0.3% delta (score 24935), and the i7-13620H with a 0.4% delta (score 24911). The GPU’s score of 27425 places it in the 72nd percentile, with the NVIDIA RTX 4090 Mobile (?) – no, wait. The nearest rival shown is the RTX 4070 Mobile at 27435 with a 0.0% delta, followed by the RTX 3090 at 27465 (delta -0.5%) and the RTX PRO 4000 Blackwell at 27123 (delta +1.1%). The fact that the CPU and GPU each sits at the 70–80 percentile in synthetic benchmarks may not translate perfectly to Rust’s specific workload. The measured FPS data demonstrates that the bottleneck alternates: at 1080p Low the CPU-driven results hit 165 FPS, while 4K Ultra drops to 30 FPS, indicating a strong GPU dependency in farm from the resolution.

Measured FPS Breakdown

1920x1080 (Full HD)

At 1080p, the lowest average frame rate observed is 71 FPS at the Ultra preset. Raising the preset from Ultra to High yields only a modest gain: the High preset goes to 93 FPS. Stepping down to Medium brings the average to 111 FPS, and the Medium preset’s minium and maximum are documented as 94 and 127, respectively – a spread of 33 frames, which suggests the frame rate spike is over the interval. The Low preset reaches up to 165 FPS, a value that indicates the CPU is not the limiting factor at the lowest settings; the GPU renders the scene with less workload. The GPU’s 12 GB VRAM and 384.0 GB/s bandwidth come into play: at this resolution, the frame buffer is likely within the 12 GB capacity, and the high bandwidth enables high texture resets, though the measured results show the difference in quality develops from 165 to 71 across the presets.

2560px1440 (WQHD)

At 2560x1440, the average frame rate for the High preset is 64 FPS, which is the lowest of the three presets. The Low preset returns 114 FPS, and Medium 114 (wait, we have Medium 76). Correct: Low 114, Medium 76, High 64, Ultra 49. The Medium preset again gives min/max of 65/88. The delta between High and Ultra is 16 FPS (from 64 to 49), indicating the cost of the Ultra settings in pixel-rich environments. The GPU is now being stretched, as shown by direct relation: the 12 GB framebuffer and the 199 GB/s internal memory bus must deliver the high bandwidth to the ROPs across a 16.2 K pixel count (assuming roughly). The CPU usage becomes less relevant because the GPU likely runs near its peak. The CPU's 12 threads at clock speeds up to 4.70, but the measured FPS drops sharply on higher settings, meaning the pixel fill rate and shader units are more important.

2160p (4K)

The 4K data shows a marginal experience: Low averages 67 FPS (the best 4K value), Medium 45 (min 38, max 52), High 38 FPS, and Ultra only 29. From the highest to the lowest, this is only a 1.9x increase – from 29 to 67. That resolution is clearly beyond the card’s comfortable envelope. The 12 GB VRAM may still be sufficient, but the fill rate is the common bottleneck: the GPU hath only 165.2 GPixel/s and a texture rate of 41.3 Gt/s (texture rate 413 GTexel/s). At 3840x2160, the pixel throughput requirement triples the workload, and this card’s pixel rate is a known limit. The CPU is not the controlling factor; the FPS across the presets is tightly bound to the GPU compute.

CPU Role

The Ryzen 5 8400F is a 6-core / 12-thread processor. For Rust, which is a low-thread-intensity title in its unoptimized aspects, the CPU provides strong single-thread performance: the 3DMark 16-thread score is 6091, but the single-thread 3DMark is 951, ranked at the 77th percentile. The base clock of 4.20 with a boost to 4.70 means the CPU can drive moderate single-thread workloads. Its TDP is only 65 W, which is low for a desktop part, allowing it to maintain high clock without excessive power draw. The L3 cache is 16 MB shared, and the L2 is 1 MB per core, which supports quick interactions with the engine.

In the measured FPS uplink, the 1080p results – where higher FPS permits an approximate 165 to 111 between Low to Medium – indicate that the CPU side is not the limiting factor until the GPU reaches its limits. Moreover, the CPU's memory bandwidth (83.2 GB/s) syncs with the DDR5 memory channel; games generally do not stress this to the same extent as the video memory. The benchmarks in the pack (Cinebench R23 multi 20851, single-core 2943) are far above what Rust would require. So the CPU stands out as the stronger half of this system, relatively, because at 1440p the gap between Low and Ultra narrows to 2.39X (114 to 49) – a sign that the GPU is now the constraint. The CPU is rated at an average score of 25005, while its closest rival 7500F is only 0.2% above. A 6-core part with high clock scales 20+ frame rate at lower resolutions, but the data shows the biggest margins come from moving the quality level, not from the CPU overclocking.

Settings Recommendations

The measured data suggests a clear prioritization: first determine the target resolution, then choose a preset that stays above 50 FPS for reactive play. At 1080p, the Medium preset yields 111 FPS, which is at minimum comfortable paste for 60Hz monitors and ideal for 60-100Hz. If the display is 144Hz, the Low preset hits 165 FPS, but that sacrifices visual fidelity; High only serves to 93 FPS. For 1080p gaming with visual quality, the dataset recommends High at 93 FPS as the best of the measured options, with the advantage that the disable and effects are fine.

For 1440p, the Medium preset is the first viable tier with 76 FPS and a stable min/max (64-88). High at 64 FPS barely stays above some -classic -motion thresholds, and Ultra drops to 24-49. For 45-64, the user can accept the high detail at 64 fps but for esports, Medium holds above 60 and gives a far safer. With known max FPS (88), the minutes stay above 64, so the Medium recommendation stands.

At 4K, no setting lives up to the General -60 FPS standard. Low is only 67, so 4K is only suitable for slow admIt or singleplayer scenes. The game shows a min of 38 on Medium, which will be noticeable. The practical recommendation is not at 4K – instead, run at 1440p Medium or 1080p High, where the measured minima remain above 60. The CPU’s boost clock and 12 threads will always be ready, and the GPU with its 12 GB of memory can cope with the large textures at 1440p. A 350 GB unconstrained by other number.

In short: choose the preset that gives at least 60 plus, and use the provided min/max frames to judge frame-time stability. This Cambridge system favors the Raster performance at 1080p/1440p, avoiding the 4K stress altogether.
