Rust

The Intel Core i5-10400F pairs a 6-core, 12-thread Comet Lake design with a 2.90 GHz base clock and a 4.30 GHz boost clock. The data shows this is a competent foundation for Rust, with the CPU’s 12 MB of shared L3 cache and dual-channel DDR4 memory support proving sufficient for the game’s demands. The benchmark scores reflect a solid mid-range part: a Cinebench R23 multi-core score of 10297 and a single-core score of 1453 place it at the 73rd percentile of all CPUs. This means the i5-10400F sits comfortably above average, but it is not a high-end part. In Rust, where server-side simulation and entity updates can stress multiple threads, the 12 threads help maintain playable frame rates, but the CPU’s single-thread performance is the more critical factor for the game’s main game loop. The 2.90 GHz base clock is modest, yet the 4.30 GHz boost ensures that lighter workloads, such as a single player in a sparsely populated area, can reach higher frequencies. The nearest rivals show the i5-10400F trading blows with the AMD EPYC 7552, which is 0.4% faster on average, while it is 0.8% faster than the AMD Ryzen 3 7320C and 1.1% faster than the Intel Core i5-8500. This indicates that for raw multi-threaded throughput, the i5-10400F is essentially on par with a server-class EPYC chip, but the real-world gaming performance is dictated more by the boost clock and architecture efficiency.

CPU Role — cores, clocks, and how they relate to this game's results

The i5-10400F’s 6 cores and 12 threads are directly relevant to Rust’s performance profile. Rust is known for being CPU-intensive, particularly in large multiplayer servers where the simulation of many players, building structures, and resource gathering can bottleneck the processor. The benchmark results confirm that the CPU holds up well at lower resolutions and settings, where the load shifts to the processor. For example, at 1080p Low settings, the combo achieves 146.7 FPS, which is a strong indication that the CPU is capable of feeding the GPU with frames when graphical load is minimal. However, the CPU’s limitations become apparent at higher settings and resolutions. At 4K Ultra, the average FPS drops to 27.7, a figure that is more likely GPU-bound, but the CPU’s single-thread score of 1453 in Cinebench R23 suggests that in heavy player-population scenarios, frame times could become inconsistent. The 2.90 GHz base clock is low for modern standards, but the 4.30 GHz boost provides a significant headroom for burst activity. The 12 MB of L3 cache is shared across all cores, which helps with random data access patterns common in Rust’s world streaming. The 3dmark scores, such as 1350 for 2 threads and 4748 for 16 threads, show a healthy scaling pattern, indicating that the CPU’s multi-threading capabilities are well-balanced for a game that can use up to 8 threads effectively. The CPU’s TDP of 65 W is modest, which means it will not cause thermal throttling in most standard air coolers, but the data suggests that the i5-10400F is a capable air cooler for this workload. The PassMark multi-thread score of 12115 further supports the notion that this is a dependable, mid-tier processor that won’t be the primary bottleneck in most Rust scenarios, but it also won’t push frame rates to extreme highs in CPU-heavy moments.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 9060 XT 8 GB is the graphical workhorse in this combo, and its specifications directly explain the measured FPS numbers. The GPU features 8 GB of GDDR6 memory on a 128-bit bus, providing 322.3 GB/s of bandwidth. This is a critical detail for Rust, which can be memory-hungry due to large texture maps and draw distances. The 8 GB capacity is adequate for 1080p and 1440p gaming, but the data shows it struggles at 4K Ultra, where the 27.7 FPS average suggests the VRAM buffer is likely maxed out, causing texture streaming to slow down. The GPU’s boost clock of 3130 MHz is exceptionally high, which helps in raw rasterization performance. The 2048 shading units and 64 ROPs are moderate, but the RDNA 4.0 architecture’s efficiency is evident in the 1080p results. At 1080p Low, the combo hits 146.7 FPS, showing that the GPU has plenty of headroom when not bound by VRAM or memory bandwidth. The memory clock of 2518 MHz (20.1 Gbps effective) is fast, but the 128-bit bus limits total bandwidth to 322.3 GB/s. This is sufficient for 1080p and 1440p, but at 4K, the memory bandwidth becomes a bottleneck. The GPU’s 150 W TDP and 1x 8-pin power connector make it a reasonable upgrade for most systems, and the 450 W suggested PSU indicates it is not a power-hungry part. The pixel rate of 200.3 GPixel/s and texture rate of 400.6 GTexel/s are high enough to handle Rust’s environmental detail at lower resolutions. The 8 GB VRAM is the defining factor here: at 1440p High, the combo manages 65.4 FPS, but at 4K High, it drops to 36.5 FPS, a 44% reduction that is directly attributable to the VRAM and bandwidth constraints. The GPU’s percentile rank of 50 places it exactly in the middle of all GPUs, meaning it is an average performer for its class, but the data shows it is well-matched for 1080p gaming.

How This Combo Ranks

The Intel Core i5-10400F and AMD Radeon RX 9060 XT 8 GB combo ranks 947th out of 1717 tested combinations for Rust. This places it in the lower-middle tier of all tested systems. The rank of 947 means that there are 770 other combos that perform better in this game, which is a significant portion. This ranking is reflective of the GPU’s average performance (50th percentile) and the CPU’s above-average performance (73rd percentile). The data shows that while the CPU is a solid performer, the GPU’s 8 GB VRAM and 128-bit bus limit its ability to handle Rust’s most demanding settings. The combo is not a high-end solution, but it is not a weak one either. The 1080p results, which are the most relevant for this tier of hardware, show that it can deliver smooth frame rates at Medium and High settings. At 1440p, it is still usable, but the frame rates drop below the 60 FPS threshold at High settings. The 4K results are poor, with all settings except Low falling below 50 FPS. This ranking suggests that users should not expect to play Rust at maximum settings with this combo, but rather stick to 1080p or 1440p with adjusted settings for a good experience. The combo’s position in the 947th spot out of 1717 is a clear indicator that it is a mainstream, budget-conscious pairing that prioritizes cost-effectiveness over raw performance.

Measured FPS Breakdown

The measured FPS data provides a clear picture of how this combo scales across resolutions and settings. At 1920x1080, the lowest resolution tested, the combo performs admirably. With Low settings, it achieves an average of 146.7 FPS, which is exceptionally smooth. Moving up to Medium settings, the average drops to 115.1 FPS, still a very playable number. High settings yield 96.4 FPS, and Ultra brings it down to 71.8 FPS. This scaling shows that the GPU and CPU are well-balanced at 1080p, with the CPU able to keep up even at Low settings where the GPU workload is light. At 2560x1440, the performance drops are more pronounced. Low settings average 113.3 FPS, which is still high, but Medium settings fall to 77.4 FPS. High settings average 65.4 FPS, and Ultra drops to 49.9 FPS. The transition from 1080p to 1440p shows a typical resolution scaling penalty, but the combo remains playable at Medium and High presets. At 3840x2160, the limitations of the 8 GB VRAM and 128-bit bus become evident. Low settings average 69.8 FPS, which is surprisingly good, but Medium settings fall to 47 FPS. High settings average 36.5 FPS, and Ultra drops to a barely playable 27.7 FPS. The data shows that the combo is only viable at 4K when using Low settings, and even then, the frame rate is not ideal for a competitive survival game. The difference between 1080p Low (146.7 FPS) and 4K Ultra (27.7 FPS) is a 81% reduction, highlighting the GPU’s memory bandwidth and capacity constraints.

Settings Recommendations

Based on the measured FPS data, the best experience for this combo in Rust is achieved at 1080p with Medium or High settings. At 1080p Medium, the combo delivers 115.1 FPS, which is a smooth and responsive experience with good visual fidelity. If a higher frame rate is preferred for competitive play, 1080p Low at 146.7 FPS is the best option, though the visual quality will be noticeably reduced. For users with a 1440p monitor, Medium settings are the sweet spot, providing 77.4 FPS, which is above the 60 FPS threshold for most players. High settings at 1440p are also viable at 65.4 FPS, but the lower frame rate may be noticeable in intense firefights. Ultra settings are not recommended at any resolution, as they produce frame rates below 72 FPS even at 1080p, and the visual improvement over High is not worth the performance cost. At 4K, the data indicates that only Low settings are playable at 69.8 FPS, but this sacrifices too much visual quality for the resolution. The recommended path is to use 1080p High for the best balance of visuals and performance, or 1080p Medium if a higher frame rate is prioritized. For 1440p, Medium is the clear choice. This combo is not suited for 4K gaming, and users with 4K displays should consider lowering the resolution to 1440p for a better experience.
