Rust

The Intel Core i5-11400F and AMD Radeon RX 7700 XT combination in Rust presents a study in balanced scaling, where the 6-core, 12-thread Rocket Lake processor provides a solid foundation for the RDNA 3.0 graphics card. The CPU operates with a base clock of 2.60 GHz and a boost clock of 4.40 GHz, built on Intel's 14 nm process with a 65 W TDP. Its 12 MB of shared L3 cache and dual-channel DDR4 memory support with 51.2 GB/s bandwidth are typical for this segment, and the data shows the processor achieves a 71st percentile ranking among all CPUs in the database. In synthetic benchmarks, the chip scores 14,340 in Cinebench R23 multi-core and 2,024 in single-core, with a Passmark multithread score of 16,908 and a single-thread score of 2,981. These numbers place the i5-11400F within a tight performance cluster, as its nearest rivals — the AMD EPYC 7H12, Intel Core i5-12450H, AMD Ryzen 3 PRO 8300G, and Intel Core Ultra 7 164U — all sit within a delta of roughly 0.6% to -0.4% of its average benchmark score of 17,177. For Rust, which is known for its server-side simulation and physics calculations, the CPU's strong multi-threaded showing in Cinebench R20 (6,022) and Passmark Physics (842) suggests it can handle the game's entity processing, though the measured FPS data indicates that at lower resolutions, the graphics card becomes the primary driver of frame rates.

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

The Core i5-11400F brings six physical cores and twelve threads to the table, a configuration that aligns with Rust's tendency to utilize multiple threads for world simulation, building physics, and player interactions. With a 4.40 GHz boost clock, the processor can deliver strong single-thread performance where needed, evidenced by its 850 score in Cinebench R20 single-core and 1,691 in 3DMark 2-thread tests. The 3DMark 16-thread score of 5,619 and max-thread score of 5,652 show that scaling beyond 8 threads yields diminishing returns, but the 12-thread capability provides headroom for background tasks and game server overhead. In the measured FPS data, the CPU's influence is most apparent when comparing 1080p Low settings (175 FPS) to 1440p Low settings (130 FPS) and 4K Low (77 FPS). The drop from 1080p to 1440p at Low settings is 45 FPS, while the drop from 1440p to 4K is 53 FPS, suggesting that at Low settings, the CPU is still capable of pushing high frame rates at 1080p, but the GPU begins to limit as resolution increases. The processor's Passmark data compression score of 208,472 and encryption score of 10,247 are relevant to Rust's procedural map generation and save-file management, though these tasks are less frame-rate-critical than the main game loop. The i5-11400F's 71st percentile ranking among all CPUs indicates it is a mid-to-upper tier processor, and its nearest rivals' scores (17,120 to 17,278) confirm that this chip sits in a crowded performance band where small deltas of 0.3% to -0.6% separate it from alternatives. For Rust specifically, the CPU's 6-core/12-thread design is sufficient to avoid becoming a bottleneck at higher settings, where the GPU's workload increases and frame rates drop to 82 FPS at 1080p Ultra and 33 FPS at 4K Ultra.

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

The AMD Radeon RX 7700 XT is built on the Navi 32 chip with RDNA 3.0 architecture, manufactured on TSMC's 5 nm process with 28,100 million transistors. It features 12 GB of GDDR6 memory on a 192-bit bus, delivering 432.0 GB/s of bandwidth — a significant asset for Rust's large open-world textures and dynamic lighting. The GPU's boost clock reaches 2,544 MHz with a game clock of 2,171 MHz, and its 3,456 shading units, 216 texture mapping units, and 96 render output units provide substantial raw compute. The card achieves a 67th percentile ranking among all GPUs, with an average benchmark score of 22,549. Its nearest rivals include the NVIDIA GeForce RTX 5060 Mobile (0.5% delta), RTX 4060 Mobile (-0.8% delta), RTX 2080 (-1.5% delta), and AMD Radeon RX 5700 (1.7% delta), showing that the RX 7700 XT is competitive with a range of previous and current-generation cards. In Rust, the GPU's role becomes increasingly dominant as settings rise. At 1080p High, the combo achieves 107 FPS, but at 1080p Ultra, it drops to 82 FPS — a 25 FPS penalty for the highest preset. The 4K results tell a clearer story: High settings yield 44 FPS, Medium 52 FPS, and Ultra only 33 FPS. These numbers indicate that the 12 GB VRAM is sufficient even at 4K Ultra (no texture-related stutters were recorded in the min FPS data), but the GPU's compute throughput becomes the limiting factor at higher resolutions. The Passmark G3D score of 22,547 and DirectX 12 score of 79 reflect the card's DirectX 12 Ultimate support, which Rust leverages for modern rendering features. The texture rate of 549.5 GTexel/s and pixel rate of 244.2 GPixel/s help explain why the card handles 1440p Medium at 88 FPS with min/max of 74/101 FPS, providing a playable experience in the game's most common resolution.

Settings Recommendations — which preset gives the best experience per the measured rows

Examining the measured FPS rows, the Medium preset offers the most balanced experience across all three resolutions. At 1080p Medium, the combo delivers 127 FPS average with a minimum of 108 FPS and maximum of 146 FPS, which is 48 FPS higher than High settings and only 12 FPS below Low settings — a negligible difference for the visual quality gain. At 1440p Medium, the average drops to 88 FPS with min/max of 74/101 FPS, still comfortably playable and 14 FPS ahead of High settings. The 4K Medium row shows 52 FPS with a minimum of 44 FPS, which dips below the 60 FPS threshold but remains playable for a survival game where reaction time is less critical than in competitive shooters. High settings at 1080p produce 107 FPS, which is acceptable, but the 25 FPS gap between High and Ultra at 1080p (107 to 82 FPS) suggests that Ultra settings tax the GPU heavily without proportional visual returns. Low settings, while delivering the highest frame rates (175 FPS at 1080p, 130 FPS at 1440p, 77 FPS at 4K), likely sacrifice too much visual fidelity for a game that relies on environmental cues for survival. The data points to Medium as the sweet spot: at 1080p, it offers 127 FPS, which is 78% of the Low preset's performance while providing substantially better visuals; at 1440p, the 88 FPS average is above the 60 FPS standard for smooth gameplay; even at 4K, the 52 FPS average is playable, and the 44 FPS minimum shows the frame time consistency is acceptable. For players prioritizing frame rate over visuals, Low at 1440p (130 FPS) provides a better experience than High at 1080p (107 FPS), indicating that the GPU has enough headroom to trade resolution for settings.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the Intel Core i5-11400F and AMD Radeon RX 7700 XT ranks 1,535 out of 3,723 tested combos in Rust, placing it in the 58.8th percentile of all configurations in the database. This ranking reflects the mid-to-upper tier positioning of both components individually — the CPU at the 71st percentile and the GPU at the 67th percentile — but the combo's overall rank is slightly lower than either component's individual percentile, suggesting that the pairing has some inefficiency in this specific game. The rank of 1,535 means that 2,188 combos perform better in Rust, while 1,535 perform worse. This places the combo in the upper half but not the top tier, which aligns with the measured FPS data showing 4K Ultra at 33 FPS (not a high-end result) but 1080p Low at 175 FPS (a very respectable figure). The CPU's nearest rivals all have average scores within 0.6% of the i5-11400F, so the ranking is not heavily influenced by CPU choice within that performance band. The GPU's nearest rivals, including the RTX 2080 (a previous-generation high-end card) and RTX 5060 Mobile (a current-generation laptop part), show that the RX 7700 XT is competitive with a wide range of hardware. The combo rank of 1,535 out of 3,723 suggests that in Rust, this pairing delivers solid but not exceptional performance — players seeking higher frame rates at 4K would need a more powerful GPU, while those targeting 1080p esports-level play could achieve higher FPS with a faster CPU, though the 175 FPS at 1080p Low already exceeds most display refresh rates.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a clear pattern of GPU-limited scaling as resolution increases. At Low settings, the combo produces 175 FPS at 1080p, 130 FPS at 1440p, and 77 FPS at 4K — representing a 25.7% drop from 1080p to 1440p and a 40.8% drop from 1440p to 4K. At High settings, the corresponding figures are 107 FPS at 1080p, 74 FPS at 1440p, and 44 FPS at 4K — drops of 30.8% and 40.5% respectively. Medium settings show 127 FPS at 1080p, 88 FPS at 1440p, and 52 FPS at 4K, with drops of 30.7% and 40.9%. Ultra settings produce 82 FPS at 1080p, 56 FPS at 1440p, and 33 FPS at 4K, with drops of 31.7% and 41.1%. The consistent percentage drops across all settings (roughly 26-32% from 1080p to 1440p, and 40-41% from 1440p to 4K) indicate that the GPU is the primary limiting component at resolutions above 1080p. The pixel count increases by 77.8% from 1080p to 1440p (2.07 million to 3.69 million pixels) and by 125% from 1440p to 4K (3.69 million to 8.29 million pixels), yet the FPS drops are smaller than the pixel increases, suggesting that the GPU has some headroom in its memory bandwidth and compute that partially absorbs the additional load. The fact that the percentage drops are nearly identical across all settings (Low, Medium, High, Ultra) further confirms that the GPU is the bottleneck at higher resolutions — if the CPU were limiting, the drops would be more pronounced at lower settings where CPU overhead is relatively higher. At 1080p Low, the 175 FPS figure is likely near the CPU's limit in Rust's single-threaded game logic, but the GPU can still keep up; at 4K Ultra, the 33 FPS result is purely GPU-bound, with the CPU having significant headroom.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers
