Rust

The AMD Ryzen 5 7500F paired with the Intel Arc B390 delivers a starkly GPU-limited experience in Rust, with performance collapsing as resolution climbs. At 1080p Low, the combo produces 76 FPS, but this drops to 53 FPS at 1440p and 31 FPS at 4K, illustrating a steep scaling curve that points directly at the graphics card as the primary bottleneck. The data shows a 59% performance loss from 1080p to 4K at Low settings, and the gap narrows at higher presets because the GPU is already saturated.

Resolution Scaling

The measured FPS data reveals a textbook case of GPU-bound scaling in Rust. At Low settings, the frame rate drops from 76 FPS at 1920x1080 to 53 FPS at 2560x1440, a 30% reduction, and then further to 31 FPS at 3840x2160, a 59% drop from the baseline. This steep decline indicates that the Intel Arc B390’s rendering throughput is the limiting factor; the CPU has ample headroom to feed frames, but the GPU cannot keep up with the increasing pixel count.

The pattern intensifies at higher quality presets. At High settings, the combo manages 43 FPS at 1080p, 30 FPS at 1440p, and just 18 FPS at 4K — a 58% loss from 1080p to 4K, nearly identical to the Low preset’s scaling. This consistency suggests that the GPU is fully utilized even at 1080p High, so additional resolution only worsens the deficit. At Ultra settings, the numbers are 33 FPS at 1080p, 23 FPS at 1440p, and 13 FPS at 4K, with the 4K figure representing a 61% drop from 1080p.

The Medium preset shows a slightly different scaling behavior. At 1080p, the average is 51 FPS with a minimum of 44 and maximum of 59. At 1440p, the average falls to 35 FPS (min 30, max 41), and at 4K, it drops to 21 FPS (min 18, max 24). The percentage loss from 1080p to 4K here is 59%, reinforcing the trend. What is notable is that the gap between Low and Medium at each resolution is relatively small — 76 vs. 51 FPS at 1080p, 53 vs. 35 FPS at 1440p, and 31 vs. 21 FPS at 4K — indicating that the GPU is struggling with even modest increases in shading load.

The limiting component is clearly the Intel Arc B390. Its 3DMark Steel Nomad DX12 score of 1482 places it in the 9th percentile of all GPUs, and its nearest rivals are NVIDIA GeForce GT 520MX (1463, 1.3% faster), GeForce 800M (1460, 1.5% faster), GT 625 OEM (1446, 2.5% faster), and GT 710 (1443, 2.7% faster). These are entry-level mobile and OEM parts, and the B390’s performance profile aligns with that tier. The GPU’s 1536 shading units, 48 TMUs, and 24 ROPs are simply insufficient for modern survival game rendering at high resolutions.

How This Combo Ranks

In the benchmark database, this specific CPU-GPU combination ranks 2601st out of 2953 tested combos for Rust. That places it in the bottom 12% of all configurations, a position that reflects the GPU’s severe performance ceiling rather than any CPU deficiency. The Ryzen 5 7500F is a capable processor, but it is paired with a graphics solution that benchmarks in the 9th percentile of all GPUs, creating a massive imbalance.

The combo rank underscores that this is not a competitive gaming setup for Rust. With only 18 FPS at 4K High and 13 FPS at 4K Ultra, the experience falls well below playable thresholds for most users. Even at 1080p, the best case scenario is 76 FPS at Low settings, which is playable but far from smooth for a game that benefits from high frame rates. The rank of 2601 out of 2953 means that 352 tested combos perform worse, but the vast majority of configurations deliver better results.

The CPU itself ranks in the 77th percentile of all processors, with an average benchmark score of 24964. Its nearest rivals include the Intel Core i7-11850H (avg score 24935, 0.1% slower), AMD Ryzen 5 8400F (25005, 0.2% faster), Intel Core i7-13620H (24911, 0.2% slower), and Intel Core 5 210H (24872, 0.4% slower). This means the Ryzen 5 7500F is a mid-to-upper tier CPU, but the Arc B390 drags the entire combo down to near-bottom rankings.

CPU Role

The AMD Ryzen 5 7500F brings 6 cores and 12 threads to the table, built on the Zen 4 architecture with a 5 nm process. Its base clock is 3.70 GHz with a boost clock of 5.00 GHz, and it features a 65 W TDP. The CPU has a 32 MB shared L3 cache, 1 MB L2 per core, and 64 KB L1 per core, with support for DDR5 memory over a dual-channel bus offering 83.2 GB/s bandwidth. These specifications make it a strong performer for gaming, but in Rust, the CPU is rarely the bottleneck.

Benchmark data confirms the CPU’s capability. In Cinebench R23, it scores 22799 multicore and 3218 singlecore. In Geekbench, it achieves 12362 multicore and 2374 singlecore. The 3DMark results show 6376 with 16 threads, 5372 with 8 threads, 3621 with 4 threads, 1902 with 2 threads, and 974 single-thread. PassMark scores include 26825 multithread and 3841 single-thread. These figures indicate a robust processor that can handle Rust’s simulation and physics workloads without breaking a sweat.

Rust is known for being CPU-intensive in its server-side and world-generation logic, but the measured FPS data shows that this combo’s frame rates are almost entirely dictated by the GPU. The fact that FPS scales downward with resolution at every preset — even Low — proves that the CPU is feeding frames faster than the GPU can render them. If the CPU were the limiting factor, frame rates would remain flat across resolutions, which is not the case. The 5.00 GHz boost clock and 6 cores are more than sufficient for Rust’s typical thread utilization, and the CPU’s 77th percentile ranking reinforces that it is not the weak link.

Measured FPS Breakdown

The measured FPS data provides a complete picture of this combo’s performance across three resolutions and four quality presets. At 1920x1080, the Low preset yields an average of 76 FPS, which is the highest frame rate recorded for this configuration. The Medium preset drops to 51 FPS average, with a minimum of 44 and maximum of 59. High settings produce 43 FPS, and Ultra falls to 33 FPS. These numbers show that even at the lowest resolution and quality, the combo cannot reach 100 FPS, and the gap between Low and Ultra is 43 FPS, a 57% reduction.

Moving to 2560x1440, the Low preset averages 53 FPS, Medium averages 35 FPS (min 30, max 41), High averages 30 FPS, and Ultra averages 23 FPS. The scaling from 1080p to 1440p at Low is a 30% drop, while at Ultra it is a 30% drop as well, showing consistent GPU limitations. The minimum FPS at 1440p Medium is 30, which is below the 33 FPS average at 1080p Ultra, highlighting how quickly performance degrades with resolution.

At 3840x2160, the results are marginal. Low settings average 31 FPS, Medium averages 21 FPS (min 18, max 24), High averages 18 FPS, and Ultra averages 13 FPS. None of these are playable for a fast-paced survival game, and the 4K Ultra figure of 13 FPS is essentially a slideshow. The minimum FPS at 4K Medium is 18, which is below the 4K Low average, suggesting occasional stutters even at the lowest quality.

The medium preset data is the only set with complete min/max figures, providing insight into frame pacing. At 1080p Medium, the range is 44 to 59 FPS, a 15 FPS spread. At 1440p Medium, the range narrows to 30 to 41 FPS, an 11 FPS spread. At 4K Medium, the range is 18 to 24 FPS, a 6 FPS spread. This tightening range at higher resolutions indicates that the GPU is consistently hitting its limits, with less variance because there is no headroom for burst performance.

Settings Recommendations

For the best playable experience with this combo, the data points clearly to 1080p Low as the only viable option. At 1920x1080 with Low settings, the combo achieves 76 FPS average, which is the sole configuration above the 60 FPS threshold. This preset offers the smoothest gameplay, though it sacrifices visual fidelity. The Medium preset at 1080p yields 51 FPS, which is playable but may feel less responsive, and the High preset drops to 43 FPS, which is borderline for a survival game where reflex timing matters.

At 1440p, the Low preset averages 53 FPS, which is technically playable but below the 60 FPS target. The Medium preset at 1440p averages 35 FPS, and the High preset drops to 30 FPS. These are not recommended for competitive play, but they could suffice for casual exploration if visual quality is prioritized. The Ultra preset at any resolution is not recommended, as it produces frame rates below 33 FPS even at 1080p.

For users who must play at 4K, the Low preset at 31 FPS is the only option above 30 FPS, but it is far from ideal. The Medium preset at 4K averages 21 FPS, and the High and Ultra presets produce 18 and 13 FPS respectively, which are unplayable. Given the GPU’s 9th percentile ranking, the best strategy is to stay at 1080p and use Low settings to maximize frame rate, or accept Medium settings for a visual upgrade at the cost of 25 FPS. The data shows no configuration that combines high visual quality with smooth performance for this hardware pairing.
