How This Combo Ranks

The AMD Ryzen 7 5700X paired with the Intel Arc B370 ranks 2710th out of 2953 tested combos in Rust, placing it in the bottom 8% of all configurations. This is a decidedly low-tier result for a game that demands both strong single-threaded CPU performance and competent GPU throughput. The ranking reflects the fundamental imbalance of this pairing: the CPU is a capable mid-range desktop part, but the GPU is a 25 W integrated-class chip that sits at the 5th percentile among all GPUs, directly competing with legacy parts like the ATI Mobility Radeon HD 5570 and ATI Radeon HD 5770.

The data indicates this combo is best understood as a CPU-limited system at lower resolutions and a GPU-limited system at higher resolutions, with neither component capable of delivering a high-refresh experience. The measured FPS ranges from 12 to 69 depending on settings and resolution, and the average performance across all tested configurations is roughly 32 FPS — playable for a survival game but far from smooth. The combo's rank is dragged down almost entirely by the GPU, as the Ryzen 7 5700X itself sits at the 79th percentile among all CPUs, with an average benchmark score of 27578 that exactly matches the Intel Core i5-12600K.

Benchmark results indicate that at 1080p Low, the system reaches 69 FPS, which is the only configuration that approaches a standard 60 FPS baseline. Every other setting and resolution combination falls below that threshold, and at 4K Ultra the system drops to a mere 12 FPS. The practical takeaway is that this combo can run Rust, but only at reduced settings and resolutions, and even then with noticeable frame rate variability in the Medium preset where min and max FPS are recorded.

Q: Does the combo perform better at 1440p or 1080p?

A: The system performs better at 1080p across all settings. For example, at High settings, 1080p yields 39 FPS while 1440p yields 27 FPS. At Low settings, 1080p yields 69 FPS while 1440p yields 48 FPS.

Q: Is there any configuration where the system maintains a consistent frame rate?

A: The Medium preset is the only one with recorded min and max FPS values. At 1080p Medium, the range is 39 to 53 FPS (average 46). At 1440p Medium, the range is 27 to 37 FPS (average 32). At 4K Medium, the range is 16 to 22 FPS (average 19).

Resolution Scaling

The FPS scaling from 1080p to 4K reveals a system that is heavily GPU-bound at higher resolutions, but with a CPU that becomes increasingly irrelevant as pixel count rises. At Low settings, the average FPS drops from 69 at 1080p to 48 at 1440p (a 30.4% decrease) and then to 28 at 4K (a 59.4% decrease from 1080p). The scaling is roughly proportional to pixel count: 1440p has 1.78 times the pixels of 1080p, and 4K has 4 times, yet the FPS drops are less severe than pixel scaling would predict, indicating some CPU headroom is being used to mitigate GPU limitations.

At High settings, the pattern shifts. The average FPS drops from 39 at 1080p to 27 at 1440p (a 30.8% decrease) and then to 16 at 4K (a 59.0% decrease from 1080p). The similarity in percentage drops across Low and High settings suggests the GPU is the primary bottleneck in both cases, but the absolute FPS values are so low that even the CPU's strong single-thread performance cannot compensate.

The limiting component analysis is clear: at 1080p, the CPU's 8 cores and 16 threads with a boost clock of 4.60 GHz are sufficient to push the GPU to its limits, but the GPU's 6.144 TFLOPS FP32 performance and 1280 shading units are simply inadequate for modern gaming. At 4K, the GPU is so overwhelmed that the CPU's role diminishes entirely — the difference between 4K Low (28 FPS) and 4K High (16 FPS) is 12 FPS, while the difference between 1080p Low (69 FPS) and 1080p High (39 FPS) is 30 FPS. This indicates that at higher resolutions, the GPU's pixel throughput (48.00 GPixel/s) and texture rate (96.00 GTexel/s) become the hard limits, regardless of CPU capability.

The data suggests that users should target 1080p with this combo, as the performance degradation to 1440p and 4K is severe and does not offer a playable experience at any setting above Low.

Measured FPS Breakdown

At 3840x2160 (4K), the system produces the following average FPS across settings: Low yields 28 FPS, Medium yields 19 FPS (with a range of 16 to 22), High yields 16 FPS, and Ultra yields 12 FPS. The spread from Low to Ultra is 16 FPS, and even the best 4K configuration (Low) falls below 30 FPS, making 4K impractical for anything other than static scenes or very slow-paced gameplay.

At 2560x1440 (1440p), the averages improve notably: Low produces 48 FPS, Medium produces 32 FPS (range 27 to 37), High produces 27 FPS, and Ultra produces 20 FPS. The Low setting at 1440p is the only configuration in this resolution that approaches playability, though 48 FPS is still below a smooth 60 FPS target. The Medium range of 27 to 37 FPS indicates significant frame time variance, which could feel stuttery in a game like Rust where sudden movements and environmental changes are common.

At 1920x1080 (1080p), the system shows its best results: Low produces 69 FPS, Medium produces 46 FPS (range 39 to 53), High produces 39 FPS, and Ultra produces 30 FPS. The 69 FPS at Low is the only configuration that exceeds 60 FPS, and the 30 FPS at Ultra is the only 1080p configuration that dips below 35 FPS. The Medium preset's range of 39 to 53 FPS suggests that even at 1080p, the system cannot maintain a consistent frame rate, likely due to the GPU's limited 20 ROPs and 40 TMUs struggling with Rust's draw calls and texture streaming.

Across all resolutions, the Ultra preset consistently delivers the lowest FPS (12 at 4K, 20 at 1440p, 30 at 1080p), while Low delivers the highest (28 at 4K, 48 at 1440p, 69 at 1080p). The performance gap between Low and Ultra widens at lower resolutions: at 1080p the gap is 39 FPS, at 1440p it is 28 FPS, and at 4K it is 16 FPS. This trend confirms that the GPU is the limiting factor, as its fixed capabilities are progressively saturated by higher settings and resolutions, leaving less headroom for visual quality improvements.

CPU Role

The AMD Ryzen 7 5700X is a Zen 3 (Vermeer) architecture processor built on TSMC's 7 nm process, featuring 8 cores and 16 threads with a base clock of 3.40 GHz and a boost clock of 4.60 GHz. Its 32 MB of shared L3 cache and 4,150 million transistors give it strong multi-threaded capabilities, as evidenced by its Cinebench R23 multi-core score of 13184 and PassMark multi-thread score of 26612. The CPU's percentile rank of 79 indicates it outperforms the majority of all processors, and its nearest rival in average benchmark score is the Intel Core i5-12600K at a 0% delta.

In Rust, the CPU's role is primarily to handle game logic, entity updates, and physics calculations, which are heavily single-threaded. The 5700X's single-thread performance is respectable but not exceptional: its 3DMark single-thread score is 921, its Cinebench R23 single-core score is 1499, and its PassMark single-thread score is 3385. These numbers place it in the mid-range of modern desktop CPUs, adequate for Rust's demands but not a bottleneck-releaser for the weak GPU.

The data shows that the CPU is not the primary constraint in this combo. At 1080p Low, the system achieves 69 FPS, and the CPU's 8 cores are likely not fully utilized — Rust typically scales well up to 4-6 threads, and the 5700X has ample headroom. However, the CPU's memory bandwidth of 51.2 GB/s (dual-channel DDR4) and PCIe Gen 4 support (20 lanes) are not leveraged effectively because the GPU uses system shared memory, which is system-dependent in bandwidth. This shared memory architecture means the GPU competes with the CPU for the same memory bandwidth, potentially causing additional latency that is not captured in the FPS averages but could affect frame pacing.

The CPU's strong multi-threaded scores (3DMark 16-thread score of 6858, PassMark multi-thread of 26612) do not translate into higher FPS in Rust because the game is not fully multi-threaded, and the GPU's 6.144 TFLOPS FP32 performance is the hard ceiling. The 5700X could theoretically support a much more powerful GPU, as evidenced by its near-identical average benchmark score to the Intel Core i5-12600K and AMD Ryzen 5 7600X, both of which are commonly paired with dedicated graphics cards.

Settings Recommendations

The measured data provides a clear hierarchy for optimal settings with this combo. The only configuration that delivers a 60+ FPS average is 1080p Low at 69 FPS, which should be the default recommendation for any user prioritizing frame rate stability. However, 69 FPS is still below the 144 Hz refresh rate that many gaming monitors support, and the lack of min/max FPS data for Low settings means frame time consistency is unknown. Users who prefer visual quality over raw FPS may consider 1080p Medium at 46 FPS (range 39 to 53), which offers a balanced experience with moderate settings and a playable frame rate, though the 14 FPS variance between min and max could cause noticeable hitches during intense moments.

At 1440p, the only viable option is Low at 48 FPS, which is close to 60 FPS but sacrifices most visual fidelity. The 1440p Medium preset at 32 FPS (range 27 to 37) is playable but marginal, and the 1440p High at 27 FPS is likely too stuttery for a survival game where quick reactions are needed. At 4K, no settings are recommended: even Low at 28 FPS is below the playable threshold, and the 16-22 FPS range at Medium makes the game feel like a slideshow.

The best experience per the measured rows is 1080p Low, as it is the only preset that exceeds 60 FPS and provides the largest performance headroom. Users who find Low settings too visually barren can try 1080p Medium, which offers a 46 FPS average and a 39-53 FPS range, but should be prepared for occasional frame drops. The Ultra preset at 1080p (30 FPS) is not recommended, as the visual gain from Medium to Ultra is typically modest in Rust while the FPS penalty is substantial (16 FPS). Similarly, the High preset at 1080p (39 FPS) offers no meaningful advantage over Medium (46 FPS) and is 7 FPS slower on average, making it the least efficient choice among the 1080p options.

For users with variable refresh rate monitors, the 1440p Low preset at 48 FPS may be preferable to 1080p Low at 69 FPS if they value higher resolution, but the 21 FPS difference is significant and should be weighed against the visual clarity gain. Ultimately, the data suggests that this combo is best suited for 1080p gaming with Low to Medium settings, and any attempt to push higher resolutions or quality presets will result in a sub-30 FPS experience that compromises gameplay.
