FAQ

Q: How does the AMD Ryzen 5 8400F compare to its closest rival in CPU benchmarks?

A: The Ryzen 5 8400F scores 25,064 on the average benchmark, which is essentially tied with the AMD Ryzen 7 2700X, which scores 25,057 — a delta of 0%. It also sits within 0.3% of the AMD Ryzen 5 7500F (24,993) and is slightly ahead of the AMD Ryzen AI 5 PRO 340 (25,099, delta -0.1%).

Q: What does the combo rank show for Rust specifically?

A: This specific CPU-GPU pairing ranks 182nd out of 1,717 tested combos in Rust. That places it in the top 11% of all configurations tested for this game, indicating a strong overall fit for the title.

Q: What is the GPU's memory configuration and how does it affect performance?

A: The RTX 4070 Ti SUPER comes with 16 GB of GDDR6X memory on a 256-bit bus, delivering 672.3 GB/s of bandwidth. This large frame buffer is particularly relevant for Rust at high resolutions, where the 4K High preset still averages 62.5 FPS without running out of memory headroom.

Q: What is the CPU's core and thread configuration?

A: The Ryzen 5 8400F has 6 cores and 12 threads, based on the Zen 4 (Phoenix) architecture on a 4 nm process. It boosts up to 4.70 GHz from a 4.20 GHz base clock, with 16 MB of shared L3 cache.

Q: Which settings preset delivers the highest frame rates at 1080p?

A: The Low preset at 1920x1080 achieves the highest measured average of 213.6 FPS. Medium follows at 179.5 FPS, while High and Ultra trail at 149.4 FPS and 114.1 FPS, respectively.

Q: How does the GPU's benchmark score compare to nearby alternatives?

A: The RTX 4070 Ti SUPER has an average benchmark score of 48,704, placing it in the 86th percentile of all GPUs. It is 2.1% ahead of the Intel Arc A550M (49,737 delta -2.1%) and 1.6% behind the NVIDIA RTX A2000 (47,915 delta 1.6%).

How This Combo Ranks

The data places this configuration at rank 182 out of 1,717 tested combos for Rust. This is a strong result, putting the pairing in the top 10.6% of all combinations. The high rank suggests that neither the CPU nor the GPU is a serious bottleneck in this title, and the system should deliver a smooth experience across most settings.

Relative to the CPU's overall percentile of 82 (vs all CPUs), the combo rank of 182/1717 shows that Rust is a game where this processor performs adequately. The GPU's 86th percentile standing complements the CPU well, and the measured frame rates confirm that the pairing is balanced. The 4K Ultra result of 46.6 FPS is the only sub-60 FPS reading, which is expected for a demanding survival title at maximum settings on a 4K display.

Given the rank, this combo sits comfortably above the median tested configuration. The top 11% placement means that most players with this hardware will get a high-refresh-rate experience at 1440p or a solid 60 FPS experience at 4K with adjusted settings.

GPU Role

The RTX 4070 Ti SUPER is built on the Ada Lovelace architecture with a 5 nm process. It has 8,448 shading units, 264 texture mapping units, and 96 raster operation processors. The chip runs at a base clock of 2340 MHz and boosts to 2610 MHz, with memory clocked at 1313 MHz (21 Gbps effective). This hardware combination yields a pixel rate of 250.6 GPixel/s and a texture rate of 689.0 GTexel/s, with FP32 performance of 44.10 TFLOPS.

The 16 GB GDDR6X frame buffer is a defining feature for Rust. At 3840x2160, the jump from Medium to High costs 10.5 FPS (73 to 62.5), but the game remains playable. The 672.3 GB/s bandwidth ensures that texture streaming in Rust's large open world does not cause stutter, as evidenced by the consistent average frame rates across repeated runs.

The GPU's average benchmark score of 48,704 places it in the 86th percentile of all GPUs. It is within 2.1% of the Intel Arc A550M (49,737) and 1.6% ahead of the NVIDIA RTX A2000 (47,915). This indicates the card is well above average, and the measured Rust performance aligns with that positioning — the 4K High average of 62.5 FPS is a strong result for a demanding survival sim.

Settings Recommendations

For the best balance of visual quality and frame rate, the Medium preset is the recommended starting point. At 1920x1080, Medium delivers 179.5 FPS, which is only 34.1 FPS behind Low but 30.1 FPS ahead of High. At 2560x1440, Medium yields 120.6 FPS, comfortably above the 106.4 FPS of High and still well within high-refresh-rate territory.

At 3840x2160, Medium drops to 73 FPS, which remains above the 60 FPS threshold for most displays. High at 4K gives 62.5 FPS, which is playable but leaves less headroom for scene complexity. Ultra at any resolution is not recommended for competitive play, as it drops to 80 FPS at 1440p and 46.6 FPS at 4K.

The Low preset at 1080p produces the highest measured average of 213.6 FPS, useful for players chasing maximum refresh rates on 240 Hz monitors. However, the jump from Low to Medium only costs 34.1 FPS at 1080p while providing improved visuals. For most users, Medium strikes the optimal compromise between image quality and performance across all three resolutions.

Measured FPS Breakdown

At 1920x1080, the configuration produces the following average frame rates:

• Low: 213.6 FPS
• Medium: 179.5 FPS
• High: 149.4 FPS
• Ultra: 114.1 FPS

The spread from Low to Ultra is 99.5 FPS, showing that settings have a significant impact at this resolution. The system can drive a 240 Hz monitor on Low, but even Ultra stays above 114 FPS.

At 2560x1440, the results are:

• Low: 180.9 FPS
• Medium: 120.6 FPS
• High: 106.4 FPS
• Ultra: 80 FPS

The 1440p results show a more compressed range, with Low being 60.9 FPS ahead of Medium. The High preset at 106.4 FPS is excellent for 1440p high-refresh-rate gaming, and even Ultra remains above 60 FPS.

At 3840x2160, the averages are:

• Low: 110.9 FPS
• Medium: 73 FPS
• High: 62.5 FPS
• Ultra: 46.6 FPS

The 4K data reveals a steep drop from Low to Medium (37.9 FPS), but the difference between Medium and High is only 10.5 FPS. Ultra is the only setting that falls below 60 FPS, making it unsuitable for smooth 4K play.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 architecture (codenamed Phoenix) on a 4 nm process from TSMC. It has a base clock of 4.20 GHz and a boost clock of 4.70 GHz, with a TDP of 65 W. The chip features 16 MB of shared L3 cache, with 64 KB L1 and 1 MB L2 per core.

In synthetic benchmarks, the CPU scores 20,851 in Cinebench R23 multi-core and 2,943 in single-core. The 3DMark scores show scaling from 951 (single-thread) to 6,165 (max threads), indicating solid multi-threaded performance for a 6-core part. PassMark multi-thread score is 24,530, with single-thread at 3,684.

The CPU's average benchmark score of 25,064 places it in the 82nd percentile of all CPUs, essentially tied with the AMD Ryzen 7 2700X (25,057, delta 0%). For Rust, which can be CPU-intensive in large bases with many entities, the 12 threads and high boost clock help maintain frame rates. The measured 1080p Low result of 213.6 FPS suggests the CPU is capable of feeding the GPU at high frame rates, even in less GPU-bound scenarios.

The Zen 4 architecture with its 4 nm process provides efficient performance per watt, and the 65 W TDP means thermal management is straightforward. The DDR5 memory support with dual-channel 83.2 GB/s bandwidth ensures the CPU has sufficient memory throughput for Rust's streaming world. The 20 PCIe Gen 4 lanes from the CPU give the GPU full bandwidth, contributing to the solid 4K performance observed in the data.
