GPU Role

The AMD Radeon RX 5700 XT is built on the RDNA 1.0 architecture using the Navi 10 chip, fabricated on TSMC’s 7 nm process. It packs 10,300 million transistors across a 251 mm² die. The GPU operates with a base clock of 1605 MHz and a boost clock of 1905 MHz, with a game clock rated at 1755 MHz. Memory runs at 1750 MHz (14 Gbps effective) across a 256-bit bus, delivering 448.0 GB/s of bandwidth.

The 8 GB of GDDR6 memory is a defining characteristic for this GPU in Rust. The game’s open-world survival mechanics require loading large environmental assets, building structures, and player-created content. At 1080p and 1440p, the 8 GB frame buffer appears sufficient, as evidenced by the playable frame rates across most settings. However, at 4K Ultra, the combination of higher resolution textures and draw distances likely strains the memory capacity and bandwidth. The 24 FPS average at 4K Ultra suggests the GPU is severely limited, potentially by both memory pressure and raw compute throughput.

The RX 5700 XT’s compute capabilities include 2560 shading units, 160 texture mapping units, and 64 raster output pipelines. The pixel rate is 121.9 GPixel/s, and the texture rate is 304.8 GTexel/s. Floating-point performance is rated at 9.754 TFLOPS for FP32 and 19.51 TFLOPS for FP16 (2:1 ratio). These specifications translate to a GPU that can handle 1080p gaming with ease but struggles when resolution and settings scale upward.

The GPU’s percentile ranking of 59 places it slightly above the median of all tested GPUs. Its average benchmark score of 16361 is remarkably close to the NVIDIA RTX PRO 6000 Blackwell (16408, -0.3% delta) and AMD Radeon PRO W7500 (16415, -0.3% delta). This clustering indicates that despite architectural differences, these cards deliver similar aggregate performance in synthetic benchmarks. In Rust specifically, the measured FPS data shows the GPU becoming the primary bottleneck at higher resolutions and quality presets.

How This Combo Ranks

In the Rust benchmark database, this combo ranks 2175 out of 2953 tested combinations. This places it in the 26th percentile of tested systems, meaning roughly three-quarters of all tested combos deliver better performance in this game. The rank reflects the GPU’s age and mid-range positioning, as the CPU is relatively modern and performs well in synthetic tests.

The CPU’s 83rd percentile ranking among all processors suggests it is not the limiting factor in most scenarios. The Ryzen 5 7400F’s average benchmark score of 32750 puts it in the same performance class as the Intel Core i5-14600T (32707, 0.1% delta) and AMD Ryzen 7 PRO 6850H (32812, -0.2% delta). This means the CPU has ample headroom for gaming workloads, including Rust’s simulation and physics calculations.

The GPU, however, ranks in the 59th percentile, which is significantly lower. The RX 5700 XT’s average benchmark score of 16361 places it near the AMD Radeon Pro 5600M (16351, 0.1% delta) and slightly below the NVIDIA RTX PRO 6000 Blackwell (16408, -0.3% delta). The disparity between CPU and GPU percentiles explains the combo’s mid-pack ranking in Rust — the CPU is capable of feeding frames faster than the GPU can render them, particularly at higher settings.

The 2175 rank indicates that for Rust players seeking high frame rates at 4K or maximum settings, this combo will underperform. However, the rank also shows that there are 778 tested combos that perform worse, meaning this pairing is far from the bottom of the database. For 1080p and 1440p gaming, the combo’s performance is more competitive, as the measured FPS data demonstrates.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest results. Low settings produce an average of 135 FPS, which is smooth for competitive play. Medium settings average 90 FPS with a minimum of 77 and maximum of 104, indicating consistent frame delivery. High settings average 76 FPS, still well within playable territory. Ultra settings drop to 58 FPS, which remains acceptable but shows the GPU beginning to strain under maximum quality demands.

Moving to 2560x1440, performance scales down predictably. Low settings average 93 FPS, a 31% reduction from 1080p Low. Medium settings average 62 FPS with a minimum of 53 and maximum of 71, which is playable but with noticeable dips. High settings average 52 FPS, approaching the edge of smoothness for fast-paced gameplay. Ultra settings average 40 FPS, which may be too low for some players.

At 3840x2160, the combo struggles significantly. Low settings average 55 FPS, which is the only 4K preset that approaches playability. Medium settings average 37 FPS with a minimum of 31 and maximum of 42, showing significant frame drops. High settings average 31 FPS, and Ultra settings plummet to 24 FPS. These numbers indicate that 4K gaming with this combo requires substantial compromises in visual quality.

The progression from 1080p to 4K shows a consistent pattern: each resolution doubling roughly halves the frame rate at equivalent settings. This linear scaling suggests the GPU is the dominant bottleneck, as CPU-bound scenarios would show less dramatic drops. The 1080p Ultra result of 58 FPS versus the 4K Ultra result of 24 FPS represents a 59% reduction, highlighting the GPU’s limitations at higher pixel counts.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals critical information about the system’s bottleneck. At Low settings, the drop from 135 FPS at 1080p to 93 FPS at 1440p is a 31% reduction. Continuing to 4K Low, the frame rate falls to 55 FPS, a 41% drop from 1440p and a 59% drop from 1080p. This scaling pattern is typical for a GPU-bound scenario, where the rendering workload increases with pixel count.

At Medium settings, the scaling is similar: 90 FPS at 1080p, 62 FPS at 1440p (31% reduction), and 37 FPS at 4K (40% reduction from 1440p). High settings show 76 FPS at 1080p, 52 FPS at 1440p (32% reduction), and 31 FPS at 4K (40% reduction from 1440p). Ultra settings follow the same trend: 58 FPS at 1080p, 40 FPS at 1440p (31% reduction), and 24 FPS at 4K (40% reduction from 1440p).

The consistent 31-32% reduction from 1080p to 1440p and the 40-41% reduction from 1440p to 4K indicate that the GPU is the primary limiter across all settings. If the CPU were the bottleneck, the frame rate drops would be less severe at higher resolutions, as the GPU would have more time to render each frame while the CPU keeps up with game logic. Instead, the steady decline suggests the RX 5700 XT’s 8 GB memory and compute resources are saturated as resolution increases.

The 4K Ultra result of 24 FPS is particularly telling. This represents a 59% drop from the 1080p Ultra result of 58 FPS. At this setting, the GPU is likely exceeding its memory bandwidth and shading capabilities, resulting in frame times that cannot sustain smooth gameplay. The 4K Medium result of 37 FPS, with a minimum of 31 FPS, shows that even moderate settings cause significant frame pacing issues at 4K.

CPU Role

The AMD Ryzen 5 7400F is a 6-core, 12-thread processor based on the Zen 4 architecture, codenamed Raphael. It operates on the AMD Socket AM5 platform with a base clock of 3.70 GHz and a boost clock of 4.70 GHz. The CPU has a 65 W TDP, making it a power-efficient option for desktop builds. It is fabricated on TSMC’s 5 nm process with 6,570 million transistors across a 71 mm² die.

The cache hierarchy includes 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 32 MB of shared L3 cache. This configuration provides ample fast memory for gaming workloads. The CPU supports DDR5 memory in a dual-channel configuration with 83.2 GB/s of bandwidth, which is modern and sufficient for the game’s data streaming requirements.

In synthetic benchmarks, the Ryzen 5 7400F demonstrates strong performance. Its Cinebench R23 multicore score is 21765, and its single-core score is 3072. PassMark tests show a multithread score of 25645 and a single-thread score of 3689. The CPU’s average benchmark score of 32750 places it in the 83rd percentile, with its nearest rivals all scoring within 0.3% — the Intel Core i5-14600T (32707), Intel Core Ultra 7 155H (32697), AMD Ryzen 7 PRO 6850H (32812), and AMD Ryzen AI 7 PRO 360 (32662).

For Rust, the CPU’s role is less about raw frame rate and more about maintaining consistent frame delivery. Rust is known for its server-side simulation and physics calculations, which can tax the CPU. The 6-core, 12-thread configuration provides enough parallelism to handle these tasks without becoming a significant bottleneck in this combo. This is evidenced by the fact that the CPU’s performance percentile (83) is much higher than the GPU’s (59), and the combo’s overall rank (2175/2953) is closer to the GPU’s percentile than the CPU’s.

The CPU’s boost clock of 4.70 GHz is beneficial for single-threaded tasks within the game engine, while the 12 threads allow for efficient multi-tasking across game systems. The 32 MB of L3 cache helps keep frequently accessed data close to the cores, reducing memory latency. The DDR5 memory support with 83.2 GB/s bandwidth ensures that the CPU can feed data to the GPU without introducing a memory bandwidth bottleneck.

The benchmark data shows that the CPU has a significant performance margin over the GPU in this pairing. The CPU’s average benchmark score of 32750 is roughly double the GPU’s score of 16361, indicating that the CPU is capable of driving frame rates much higher than the GPU can render. In Rust, this means that at lower resolutions and settings, the GPU will always be the limiting factor. Only at 4K Ultra, where the GPU is severely overloaded, might the CPU’s performance characteristics come into play, and even then, the GPU’s limitations dominate the results.
