Rust

The Intel Core i5-14400F and AMD Radeon RX 6700 XT combination delivers a playable Rust experience, but one that is heavily dependent on both resolution and quality settings. The measured data reveals a system where the GPU becomes the primary constraint at higher resolutions, while the CPU has sufficient headroom to drive high frame rates at 1080p. This analysis breaks down the measured FPS across three resolutions and four quality presets, placing the results in context against other tested configurations.

Resolution Scaling

The frame rate data from this combination shows a clear pattern of GPU-bound scaling as resolution increases. At 1080p with Low settings, the combo achieves 165.4 FPS, which drops to 112.5 FPS at 1440p and further to 69.9 FPS at 4K. This represents a 57.7% performance reduction from 1080p to 4K at Low settings, indicating that the RX 6700 XT's rendering throughput is the limiting factor as pixel count climbs.

The scaling behavior changes with quality presets. At High settings, the drop from 1080p to 1440p is 29.2% (93.1 to 65.9 FPS), while the drop from 1440p to 4K is 42.9% (65.9 to 37.6 FPS). The steeper decline at higher resolutions suggests that the GPU's memory bandwidth and compute resources are being saturated. The RX 6700 XT features 12 GB of GDDR6 memory on a 192-bit bus, providing 384.0 GB/s of bandwidth, which is a key factor in handling the increased texture and shading workloads at 4K.

Ultra settings amplify this effect. The 4K Ultra result of 30.2 FPS is just 43.7% of the 1080p Ultra figure of 70.6 FPS. This confirms that the GPU is the bottleneck at 4K, as the CPU's performance remains constant regardless of resolution. The i5-14400F's boost clock of 4.70 GHz and 10 cores (16 threads) provide ample processing power for Rust's simulation and entity logic, but the frame rate ceiling at 4K is clearly set by the graphics card.

Interestingly, the Medium preset shows a different scaling curve. From 1080p (110.6 FPS) to 1440p (78.9 FPS) the drop is 28.7%, but from 1440p to 4K (46.9 FPS) the drop is 40.6%. This nonlinearity suggests that Medium settings strike a balance where both CPU and GPU contribute to performance at 1080p, but the GPU still dominates at higher resolutions. The data indicates that for 4K gaming, users should expect to use Low or Medium settings to maintain playable frame rates, as High and Ultra fall below 40 FPS.

How This Combo Ranks

In the overall benchmark database, this CPU-GPU pairing ranks 907th out of 1717 tested combinations for Rust. This places it in the 47th percentile, meaning roughly 53% of tested combos deliver higher frame rates. The rank reflects the mid-range positioning of both components: the i5-14400F sits at the 88th percentile among all CPUs, while the RX 6700 XT is at the 77th percentile among all GPUs.

The AMD Radeon HD 7950 and RX 480 both score slightly higher in the aggregate benchmark (34050 and 34059 respectively), but these are older architectures with different feature sets. In Rust specifically, the measured FPS shows that this combo can hit 165.4 FPS at 1080p Low, demonstrating that the GPU is capable of high refresh rate gaming when settings are reduced.

The rank of 907 out of 1717 underscores that this is not a top-tier combination for Rust. However, the data shows it handles 1080p and 1440p well across most settings, with only 4K Ultra falling below 31 FPS. The combination's mid-pack ranking is consistent with its component positioning: a solid 1440p performer that struggles at 4K with high presets.

CPU Role

The Intel Core i5-14400F is a 10-core, 16-thread processor based on the Raptor Lake architecture, manufactured on Intel's 10 nm process. Its base clock of 2.50 GHz boosts to 4.70 GHz, and it supports both DDR4 and DDR5 memory. In synthetic benchmarks, the CPU achieves a Cinebench R23 multicore score of 21914 and a single-core score of 3093, indicating strong multi-threaded performance for a mid-range desktop chip.

In Rust, the CPU's role is evident in the scaling of frame rates across resolutions. At 1080p Low, the combo hits 165.4 FPS, which is likely near the CPU's practical limit for this game given the single-threaded nature of many game logic tasks. The i5-14400F's single-core performance, as measured by Geekbench at 2333, is adequate for Rust's entity processing and server communication, but the game's optimization means that even a capable processor like this cannot push much beyond 165 FPS in this scenario.

The CPU's 20 MB of shared L3 cache and 1.25 MB L2 cache per core help with data locality in Rust's open-world environment, where many objects and entities need to be tracked simultaneously. The PassMark multithread score of 25783 and physics score of 1594 suggest that the CPU handles complex simulations well, which is relevant for Rust's building mechanics and resource gathering systems.

Compared to its nearest rivals in synthetic benchmarks, the i5-14400F performs nearly identically to the Intel Core i7-12800H and AMD Ryzen 5 PRO 7645. This means that in CPU-bound scenarios at 1080p, users should expect similar performance from these processors. However, the measured FPS data shows that even at 1080p, the GPU is not fully saturated at lower settings, indicating that the CPU is keeping pace with the RX 6700 XT's output.

GPU Role

The AMD Radeon RX 6700 XT is built on the RDNA 2.0 architecture with a 7 nm process from TSMC, featuring 2560 shading units and 40 ray tracing cores. Its game clock is 2424 MHz with a boost clock of 2581 MHz, and it comes with 12 GB of GDDR6 memory on a 192-bit bus, delivering 384.0 GB/s of bandwidth. These specifications position it as a solid 1440p card, which is reflected in the measured Rust performance.

The GPU's compute capabilities, rated at 13.21 TFLOPS FP32, are directly relevant to Rust's rendering workload. At 1080p Low, the combo reaches 165.4 FPS, showing that the GPU has headroom when the pixel count is low. However, at 4K, the GPU's pixel rate of 165.2 GPixel/s becomes a constraint, as the frame rate drops to 37.6 FPS at High and 30.2 FPS at Ultra.

The 12 GB VRAM capacity is notable for Rust, which can be memory-intensive due to large maps and many objects. The GPU's memory bandwidth of 384.0 GB/s helps maintain texture streaming performance, but at 4K Ultra, the combination of high resolution and detailed settings overwhelms the GPU's processing units. The PassMark G3D score of 19786 places the RX 6700 XT at the 77th percentile among all GPUs, confirming its mid-to-upper-mid-range positioning.

The GPU's nearest rival, the RX 6800, is only 0.7% faster in average benchmark scores, suggesting that the RX 6700 XT is close in performance to higher-tier cards from the same generation. However, in Rust, the measured data shows that the GPU becomes the bottleneck at 1440p and above, indicating that users seeking 4K performance would need a significantly more powerful card. The GPU's DirectX 12 Ultimate support and 12_2 feature level ensure compatibility with modern rendering techniques, though Rust's visual style does not heavily leverage these features.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend on the target resolution and desired frame rate. For 1080p gaming, the Low preset delivers 165.4 FPS, which is ideal for high refresh rate monitors. The Medium preset at 110.6 FPS also provides a smooth experience with better visuals, while High at 93.1 FPS and Ultra at 70.6 FPS remain playable. Given the CPU's apparent limit around 165 FPS, users with 144Hz monitors should use Low or Medium at 1080p to maximize frame rates.

At 1440p, the Medium preset offers the best balance with 78.9 FPS, while High at 65.9 FPS is also acceptable. The Ultra preset drops to 50.9 FPS, which may feel less smooth but is still above 30 FPS. Users prioritizing visual fidelity over frame rate can use High, while those seeking the smoothest experience should stick with Medium. The Low preset at 112.5 FPS is available for competitive play, though the visual compromise is significant.

For 4K gaming, the data strongly suggests using the Low preset, which delivers 69.9 FPS. The Medium preset at 46.9 FPS is borderline, and High (37.6 FPS) and Ultra (30.2 FPS) fall below comfortable playability thresholds. Given the GPU's limitations at 4K, users should either reduce resolution or accept lower settings. The recommended configuration is 1440p Medium for the best overall experience, as it provides a frame rate above 60 FPS while maintaining reasonable visual quality. For 1080p users, Medium or High settings offer a good balance, with Low reserved for maximum performance.
