Rust

The Intel Core i5-14400F and AMD Radeon RX 7900 XT compose a mid-high-tier desktop setup that must be evaluated through measured frame data rather than synthetic averages. In Rust—a survival game known for its heavy CPU simulation load and large-scale dynamic world-building—the pairing produces a wide spread of performance, scaling from playable at 4K Ultra to excellent at 1080p Low. The measured FPS points for this combination are all real and reproducible, and they show a typical behavior: at 4K the GPU becomes the primary limiting factor, while at 1080p the game’s CPU-bound nature raises the importance of the 10-core/16-thread i5. This analysis breaks down the twelve recorded frame-rate data points, ranks the pairing against other tested configurations, and answers common questions about how to get the most out of the setup.

Settings Recommendations

From the measured rows, the best experience is strongly tied to target resolution. At 1080p, every preset reaches at least 105 average FPS. The Ultra preset hits 105, High 137, Medium 163, and Low 217. For the high refresh—rate display, even Ultra remains above 100 FPS, so you can enable near-max settings without sacrificing fluidity. However, the difference between Low and Ultra is a 224% average increase in FPS (217 vs. 105), but that’s a small margin of playtime. For a smoother and easier, 94 frames per second is a comfortable real-world target. Many players prefer to keep high average FPS over maximal fidelity; for that purpose, Medium or High at 1080p is ideal. There is no reason to drop to Low unless aiming for only the most extreme refresh rates.

At 1440p, the presets deliver: 72 average on Ultra, 95 on High, 112 on Medium, and 167 on Low. Warning at Ultra’s 72 is still fine for a 75Hz or 144Hz panel, but the jump to 1440p when you want a solid 100+ experience requires Medium. High keeps you close to 95, but the gap between High and Ultra is a 69-pik difference (95 vs 112 for Medium; actually only 72 vs 95 vs 112, so Medium is dramatically up). For balanced picture, High strikes a fine spot; if you must use Ultra, expect slightly under 100.

At 2160p (4K), the average FPS for Low, Medium, High, and Ultra are 99, 66, 56, and 42. Only Low reaches into the guaranteed stable territory above 90 FPS. Medium is playable on a high refresh premium (min 56, max 76), but hard to support consistently. High is on border bask, with 56 average. If you want a reliable 4K experience, choose Low or accept that Ultra may dip to an uncomfortable direction. The data shows no reason to pick Ultra at 4K unless you must use max settings and are fine with 42 average.

Thus, the recommended preset per resolution is: Medium at 1080p and 1440p for balanced smoothness and visuals, and Low at 4K to achieve 99 FPS. Keep in mind that Medium at 4K also gives 66, but with lower motion smoothness; we stress—no, we observe that the 1% lows are not recorded for Low, so we stop.

GPU Role

The RX 7900 XT brings a 20 GB GDDR6 memory pool, 800.0 GB/s memory band width, and a game clock of 2025 MHz (boost 2394). In Rust, GPU overhead translate directly to pixel fill and memory bandwidth for long view distances and large textures. The 20 GB VRAM is more than enough for even heavily modded servers, and the 800.0 GB/s memory bus ensures that texture streaming doesn’t become a choke point. The 300 W board power source means that the card can draw substantial current, but the game does not push it beyond the set TDP.

When running Rust at 4K Ultra, the GPU is clearly the limiting factor, since average FPS drops to 42 while at 1440p it is 72. Raising resolution from 1440p to 4K at Ultra causes a 125% decrease in frame outcomes (72 to 42). This is typical of a GPU-bound scenario. At 1080p, Presets seem limited by the CPU; the 7900 XT can push to 217 FPS on Low, but the CPU may not always be capable of that many rendered frames per second due to simulation. The RX 7900 XT’s (TDP 300 W) robust output is only partially used at 1080p, as the CPU becomes the bottleneck.

The GPU’s role also is evident in the Low preset averages: 4K Low is 99, 1440p Low 167, and 1080p Low 217. Those increments are linear relative to pixel count, indicating the GPU scales fully until it hits a CPU ceiling at 1080p. The 217 marks the edge for the i5-14400F in this combination.

In benchmark-collation, the RX 7900 XT lands in the 55th percentile of all GPUs, with an average benchmark score of 13745. Its nearest rivals (from the data) are the AMD Radeon 660M (delta −0.5%), the NVIDIA RTX A2000 Mobile (−0.5%), AMD Radeon RX 570X (−0.9%), and AMD Radeon RX 9070 XT (+2.0%). These relative scores hint at the 7900 XT’s placement as a high-end but not flagship card.

How This Combo Ranks

Among all 3723 hardware combinations tested in Rust, this setup is ranked 682—the 82nd percentile of the field. That places it above the vast majority of tried pairings, reflecting that the 14400F+RX 7900 XT is a well matched machine for 1440p. Only 681 other combos reach faster average frames across the board, so this build is in the top ~18 %. The GPU’s own percentile is 55th, while the CPU’s is 83rd; the likely reason for a comparative higher rank is the combination of the GPU’s wavelength and the CPU’s single‑thread performance. When we look at the i5-14400F’s nearest rivals (benchmarked by average score), it sits within 0.5% of the Intel Core i7-12800H, and 0.1% from the AMD Ryzen 7 PRO 8840U. Those are relatively close in synthetics; apply the game, the actual frame results above show that the low-tier CPU does not hold back the RX 7900 XT at 4K, but at 1080p the CPU becomes a ‘’9” (There’s no direct check). The combo rank is based on the full dataset of Rust frames, so it naturally reflects the only measured details we have.

Measured FPS Breakdown

For this pairing, the measured rows across four resolutions and four settings are the core evidence:

3840×2160 (4K)

• Low: 99 average FPS (minimum not recorded).
• Medium: 66 average, min 56, max 76.
• High: 56 average.
• Ultra: 42 average.

(Deliberately note that 42 is the lowest average frame rate among all recorded settings.)

2560×1440

• Low: 167.
• Medium: 112, min 95, max 129.
• High: 95.
• Ultra: 72.

1920×1080

• Low: 217.
• Medium: 163, min 138, max 187.
• High: 137.
• Ultra: 105.

These numbers illustrate the scaling. From 1080p Low to 4K Low, the frame count falls by 118 FPS: a 54% drop. A relative sense of the GPU load is found when comparing the drop from 1080p to 1440p for each preset: Low drops by 50 (217→167), Medium by 51 (163→112), High by 42 (137→95), Ultra by 33 (105→72). The slopes show that the Ultra is moving into a GPU‑limited region at 4K, where the scaling isn’t as steep——the gap from 1440p Ultra (72) to 4K Ultra (42) is 30 FPS, which is a 41% reduction. Meanwhile, from 1440p Low to 4K Low, 99 to 167 is only 68% of the original, indicating that the CPU’s ability to keep up at low quality is also affecting the numbers.

FAQ

Q: Is the RX 7900 XT able to run Rust at 4K with smooth gameplay?

A: Based on the data, it can reach 56 average on High and 66 average on Medium, but if you want solid stability above 60 direct, 84 FPS might be enough only on Medium (min has 56, max 76). If you require 60+ average, choose Medium 4K.

Q: Which preset gives the best frame per details in 1440p?

A: At 1440p, the measured average for High is 95 FPS and for Medium 112, while Ultra is 72. For the best balance, High offers a slight fidelity advantage over Medium at a drop of just 1–62 FPS (95 vs 112), yet the difference might not be noticeable. If you want the highest FPS, choose Low for 109, or else Medium.

Q: Does this combination scale well from 1080p to 4K?

A: The combination fails to sustain a 60 FPS at 4K Ultra, but it does blast through the same settings at 1080p (over 105 FPS). The game is much more demanding in 4K, so the drop is drastic.

Q: What reason for a lower GPU percentile (55%) compared to the CPU’s 83%?

A: The RX 7900 XT’s average benchmark score (13745) is only 55% better than all GPUs, while the i5-14400F’s 83rd percentile indicates the CPU is stronger relative to its market. This game would be more CPU‑intensive at 1080p, using that CPU strength, but at 4K the GPU weakness is exposed.

Q: Is 20 GB VRAM enough for Rust?

A: The card has 20 GB GDDR6, which is substantially more than required. Rust’s textures and large maps loads fine, and the 800.0 GB/s bandwidth keeps streaming quick.

Q: How does this CPU compare to its closest benchmark rivals?

A: The i5-14400F’s nearest rival, the AMD Ryzen 7 PRO 8840U, is within 0.1% of its average score; the Intel Core i9-11900 is 0.2% higher, and the AMD Ryzen 7 6800HS is 0.2% lower. This narrow gap in synthetic tests means the CPU doesn’t pull far ahead of its peers, but its actual strength in Rust is clear from the FPS results.

CPU Role

The Core i5-14400F uses the ark Raptor Lake (Raptor Lake-R) layout, with 10 cores (6 P-cores and 4 E-cores) and 16 threads. The base clock is 2.50 GHz, with a boost of up to 4.70 GHz. The CPU’s cache hierarchy includes 1.25 MB L2 per core and a shared 20 MB L3. This configuration directly affects Rust’s heavy simulation loops, which rely on high single‑thread performance for the game logic and many-threaded games for items/entity cycles. The data never measured CPU‑only output, but we can infer its role from the frames at 1080p: the LPU’s having less to do with GPU while the CPU continues to update game draw calls. At 4K, the core usage drops since the GPU becomes limiting, and the CPU’s role is diminished.

The i5-14400F has a 83rd percentile across all CPUs and a Cinebench r23 multi-core score of 21645 and single-core of 3055. These numbers show a clear strength in, threading, yet the 4.70 GHz single‑core boost is the driving force for Rust’s real. The 20 MB L3 cache can keep the game’s hot data close, and the 10‑core / 16‑threads layout is enough for the Rust server update, though it will run at high frequency. There is no benchmark dedicated to Rust single‑thread directly, but the high Cinebench r23 single score (3055) reduces the CPU’s capacity amid a graph. Looking at the nearest rivals: the i7-12800H has an average score 0.5% higher, maybe meaning that i5-14400F trails in synthetic loads, yet Rust’s own workloads exhibit the same proximity. The 10 nm process, 65 TDP, and Intel Socket 1700 make this a sustainable choice for this GPU combination.

The combo rank of 682 out of 3723 also shows that the 8. (overall) active. Without comparing to other combinations, the i5-14400F does not bottleneck this GPU in the majority. The only clear CPU-int restriction is seen at 1080p on Low, where the game hits 214 FPS—likely right at that particular CPU’s top, but it does not go below 229. Thus at the measured settings, the CPU role is mainly to maintain that the GPU has enough data; it successfully does so across all presets, and the final FPS numbers are a sign of that.
