Rust

The Intel Core i5-13400F paired with the AMD Radeon RX 6650 XT delivers a playable but demanding experience in Rust, with performance that varies dramatically based on your resolution and quality targets. This combination sits in the 63rd percentile of tested configurations for this title, indicating a mid-pack performer that requires careful settings management to hit smooth frame rates, especially at higher resolutions. The data shows a system that is clearly capable at 1080p but struggles to maintain consistency as pixel count increases.

Resolution Scaling

The performance drop from 1080p to 4K is steep and reveals a system that becomes GPU-bound very quickly. At High settings, the average frame rate falls from 78.4 FPS at 1920x1080 to 53.8 FPS at 2560x1440, a reduction of roughly 31%. Pushing further to 3840x2160 yields just 34.3 FPS, which is a 56% decline from the 1080p result. This scaling pattern indicates that while the CPU has enough headroom at lower resolutions, the RX 6650 XT's 8 GB of memory and 128-bit bus become significant limiting factors as the pixel workload expands.

The gap between Low and Ultra settings widens considerably at higher resolutions. At 1080p, the difference between Low (143.4 FPS) and Ultra (62.8 FPS) is 80.6 FPS. At 1440p, that spread grows to 55.5 FPS (100.8 vs 45.3). At 4K, the delta is 33.9 FPS (57.9 vs 24.0). This widening gap suggests that the GPU's compute resources are being saturated by the combination of high resolution and demanding visual effects, leaving less room for settings headroom. The 4K Ultra result of 24 FPS is essentially unplayable, while 4K Low at 57.9 FPS is borderline acceptable for casual play.

The scaling from Medium to High is relatively modest at each resolution, with 1080p dropping from 99.1 to 78.4 FPS, 1440p from 64.1 to 53.8 FPS, and 4K from 41.8 to 34.3 FPS. This indicates that the jump between these presets is where the GPU starts to feel the strain, but the most punishing transition is from High to Ultra, which costs roughly 20% performance at every resolution.

Settings Recommendations

For a smooth experience at 1920x1080, the Medium preset at 99.1 FPS offers the best balance of visual quality and performance. It delivers nearly 100 frames per second while maintaining a reasonable level of detail. High settings at 78.4 FPS are also viable for those who prioritize visuals, but the jump to Ultra at 62.8 FPS sacrifices too much smoothness for marginal graphical gains. Low settings at 143.4 FPS are only recommended for competitive play where maximum frame rate is paramount.

At 2560x1440, the situation becomes more constrained. Medium at 64.1 FPS is the sweet spot, providing a fluid experience that stays above the 60 FPS threshold. High at 53.8 FPS is playable but noticeably less smooth, while Ultra at 45.3 FPS dips into uncomfortable territory for fast-paced survival gameplay. Low at 100.8 FPS remains an option for those who prefer responsiveness over fidelity.

The 3840x2160 results are largely disappointing. Medium at 41.8 FPS and High at 34.3 FPS are both below the playability threshold, while Ultra at 24 FPS is a slideshow. Low at 57.9 FPS is the only preset that approaches playability, but it requires sacrificing nearly all visual quality. This combination is not suited for 4K gaming in Rust unless you are willing to accept significant compromises.

GPU Role

The AMD Radeon RX 6650 XT features 8 GB of GDDR6 memory on a 128-bit bus, delivering 280.3 GB/s of bandwidth. With a base clock of 2055 MHz and a boost clock of 2635 MHz, the card offers 10.79 TFLOPS of FP32 compute performance. These specifications place it in the 72nd percentile of all GPUs, with an average benchmark score of 29024. Its nearest rivals include the RX 6800M, RX 470, and Arc A370M, all within 0.6% of its score, indicating a tightly contested performance tier.

In Rust, the GPU's memory bandwidth appears to be a critical constraint at higher resolutions. The 128-bit bus is narrow by modern standards, and the 8 GB capacity becomes a limiting factor when textures and effects scale up. The performance degradation from 1440p to 4K is more severe than typical for this GPU class, suggesting that Rust's rendering workload is particularly sensitive to memory bandwidth and capacity. The card's 64 ROPs and 128 TMUs handle the game's geometry and texture work adequately at lower resolutions, but the 4K results show the limits of this configuration.

The GPU's DirectX 12 Ultimate support and 32 ray accelerators are present, but Rust does not appear to leverage these features heavily based on the measured frames. The Vulkan score of 93769 and Metal score of 109922 indicate solid API support, yet the game's performance is more dependent on raw rasterization throughput. The card's power draw of 176 W with a suggested 450 W PSU is reasonable for a mid-range build, and the dual-slot design with a single 8-pin connector makes it easy to install.

Measured FPS Breakdown

At 1920x1080, the RX 6650 XT delivers its best results. Low settings produce an average of 143.4 FPS, which is excellent for competitive play. Medium yields 99.1 FPS, High drops to 78.4 FPS, and Ultra bottoms out at 62.8 FPS. These numbers show a clear hierarchy where each settings tier costs roughly 20-25 FPS, with the gap between Low and Medium being the largest at 44.3 FPS.

Moving to 2560x1440, the performance takes a significant hit. Low averages 100.8 FPS, which is still very playable. Medium drops to 64.1 FPS, High to 53.8 FPS, and Ultra to 45.3 FPS. The scaling from 1080p to 1440p at each preset is consistent, with roughly a 30-40% reduction in frame rate. This resolution is the practical ceiling for this combo if you want to maintain 60 FPS, and only at Medium settings or lower.

At 3840x2160, the results are disappointing but not surprising given the GPU's specifications. Low manages 57.9 FPS, Medium drops to 41.8 FPS, High to 34.3 FPS, and Ultra to 24.0 FPS. The 4K resolution is clearly beyond this GPU's comfortable operating range, and even Low settings barely reach playable frame rates. The gap between 1440p and 4K is steep, with over a 40% performance drop at every preset level.

How This Combo Ranks

This specific CPU-GPU combination ranks 1084th out of 1717 tested configurations for Rust, placing it in the 63rd percentile overall. This is a middle-of-the-pack result, indicating that many other hardware pairings deliver better performance in this title. The ranking suggests that while this combo is far from the worst, it is not optimized for Rust's demanding survival gameplay, which tends to favor stronger single-core CPU performance and higher GPU memory bandwidth.

The rank position makes sense given the measured results. At 1080p, the combo performs adequately, but Rust's optimization challenges and the GPU's 8 GB memory limit hold it back at higher resolutions. The CPU's 82nd percentile ranking among all processors (with an average benchmark score of 25236) is stronger than the GPU's 72nd percentile, suggesting that the graphics card is the primary bottleneck in this pairing. The nearest CPU rivals include the Core i7-13620H and Ryzen 5 5600X3D, all within 0.5% of the i5-13400F's score, confirming the processor is a capable partner.

CPU Role

The Intel Core i5-13400F provides 10 cores and 16 threads, with a base clock of 2.50 GHz and a boost clock of 4.60 GHz. This Raptor Lake architecture processor has 20 MB of shared L3 cache and supports both DDR4 and DDR5 memory. In synthetic benchmarks, it scores 21279 in Cinebench R23 multi-core and 3004 in single-core, with a PassMark multithread score of 25032. These results place it in the 82nd percentile of all CPUs, with an average benchmark score of 25236.

In Rust, the CPU's role becomes more apparent at lower resolutions where the GPU is not fully saturated. The 1080p Low result of 143.4 FPS shows that the i5-13400F can feed the GPU effectively, as the frame rate is high enough to indicate headroom. However, the single-core performance of 3004 in Cinebench R23 is moderate, and Rust's reliance on single-threaded physics and world simulation means this processor may limit performance in heavily populated areas. The 10-core configuration with 16 threads provides solid multi-threaded capability, which helps with background tasks and server processing, but the game's core loop is largely single-threaded.

The CPU's benchmark rivals are telling. The Ryzen 5 5600X3D, a gaming-focused processor with 3D V-Cache, scores within 0.5% of the i5-13400F on average. This suggests that in CPU-bound scenarios, these processors perform similarly, but the 5600X3D's cache advantage might offer better frame pacing in Rust. The Core i7-13620H, a mobile part, also scores within 0.1%, indicating that the desktop i5-13400F is not significantly stronger than some laptop chips in this workload. The data shows that the CPU is not the limiting factor in this combo at 4K, where the GPU is clearly overwhelmed, but it may hold back performance at 1080p in certain in-game situations.
