Rust

The AMD Ryzen 5 3600 paired with the Intel Arc B390 presents a curious case for running Rust. The CPU is a solid 6-core, 12-thread part from the Zen 2 generation, but the GPU is an integrated graphics solution based on the Xe3-LPG architecture. The recorded data reveals a significant bottleneck, with the playable threshold of 60 FPS only being reached at a single resolution and preset combination. This analysis breaks down the measured performance, ranking, and component roles to determine exactly what this combo can deliver.

Best Settings per Resolution

The data shows that this combination struggles to maintain fluid frame rates at higher resolutions. The most demanding preset that stays at or above 60 FPS is the only metric that matters here, and the results are stark:

• 3840x2160 (4K): No settings preset achieves 60 FPS. The highest average recorded is 31 FPS at Low settings, with Medium at 21 FPS, High at 18 FPS, and Ultra dropping to 13 FPS. None of these are playable.
• 2560x1440 (1440p): No settings preset achieves 60 FPS. The Low preset comes closest with an average of 53 FPS, but it falls short of the 60 FPS threshold. Medium averages 35 FPS, High averages 30 FPS, and Ultra averages 23 FPS.
• 1920x1080 (1080p): The Low preset is the sole qualifying configuration, delivering an average of 76 FPS. This is the only playable setting at any resolution. The Medium preset averages 51 FPS, High averages 43 FPS, and Ultra averages 33 FPS, all below the threshold.

The verdict is clear: 1080p with the Low preset is the only viable path to a smooth experience. The gap between Low and Medium at 1080p is substantial, indicating that the GPU is quickly overwhelmed by increased graphical demands.

How This Combo Ranks

In the database's comprehensive testing of 3,723 different CPU and GPU combinations for Rust, this specific pairing ranks at 3,312. This places it in the bottom 11% of all tested combos, highlighting its limited capacity for this particular game. The percentile ranking for the GPU alone is 9, meaning it performs better than only 9% of all tested graphics cards. The CPU, in contrast, sits at the 71st percentile, indicating a strong processor that is being held back by the integrated graphics.

This massive discrepancy between the CPU's potential and the GPU's delivery is the defining characteristic of this setup. The Ryzen 5 3600 is a capable processor, but the Arc B390's integrated nature creates a severe performance ceiling that the CPU cannot overcome. The ranking reflects this, placing the combo far lower than the CPU's individual standing would suggest.

FAQ

Q: Can this PC run Rust at 4K resolution?

A: No. The recorded data shows no playable settings at 3840x2160. The highest average FPS is 31 on the Low preset, with Ultra dropping to 13 FPS, all far below the 60 FPS playable threshold.

Q: What is the best possible experience this combo can offer?

A: The only configuration that clears the 60 FPS threshold is 1920x1080 with the Low preset, which averages 76 FPS. This is the sole playable setting according to the verdict by resolution.

Q: How does the Intel Arc B390 compare to its nearest rivals?

A: The Arc B390's average benchmark score is 1482. Its closest rival, the NVIDIA GeForce GT 520MX, scores 1463, a delta of 1.3%. Other near rivals include the GeForce 800M (1460, 1.5% delta) and the GeForce GT 625 OEM (1446, 2.5% delta). Performance is within a few percentage points of these older, low-end parts.

Q: Is the CPU or GPU the limiting factor in this setup?

A: The data strongly indicates the GPU is the bottleneck. The Arc B390 ranks in the 9th percentile among all GPUs, while the Ryzen 5 3600 ranks in the 71st percentile among CPUs. The massive difference in relative performance shows the integrated GPU cannot keep up with the processor.

Q: What happens to frame rates when going from Low to Medium settings at 1080p?

A: The average FPS drops from 76 at Low to 51 at Medium, a significant decrease of 25 FPS. This steep decline suggests the GPU's limited shading units and memory bandwidth are quickly saturated by even a modest increase in graphical fidelity.

Q: Is the Ryzen 5 3600 a weak processor for gaming?

A: No, the CPU benchmarks are respectable. For example, it scores 15,045 in Cinebench R23 multi-core and 1,536 in Geekbench single-core. Its nearest rivals include the Intel Core i5-11400 and Intel Core i7-1260P, with average scores within 0.2% of each other. It is a capable CPU that is simply paired with an underpowered GPU.

Similar Performance Alternatives

Looking at the nearest rivals for both components gives a sense of what hardware would behave similarly. For the CPU, the AMD Ryzen 5 3600 has an average benchmark score of 17,035. Its closest matches are the Intel Core i5-11400 (17,067, 0.2% faster), the AMD EPYC 7573X (17,070, 0.2% faster), and the Intel Core i7-1260P (17,007, 0.2% slower). These processors would offer a nearly identical CPU-bound experience.

For the GPU, the Intel Arc B390's average score is 1,482. Its direct competitors are all NVIDIA parts: the GeForce GT 520MX (1,463, 1.3% slower), the GeForce 800M (1,460, 1.5% slower), the GeForce GT 625 OEM (1,446, 2.5% slower), and the GeForce GT 710 (1,443, 2.7% slower). Any of these GPUs would produce frame rates in the same low range, confirming that the Arc B390 sits at the very bottom of the performance spectrum.

CPU and GPU Roles

The division of labor between the Ryzen 5 3600 and the Arc B390 is heavily skewed. The CPU is demonstrably the stronger component. Its individual benchmarks, such as a 15,045 in Cinebench R23 multi-core and a 2,562 in Passmark single-thread, show it is a capable modern processor. The GPU, however, is an integrated part with a 3DMark Steel Nomad score of just 1,482, placing it in the 9th percentile.

The scaling between resolutions and presets confirms the GPU is the primary constraint. At 1080p, the Low preset hits 76 FPS. Moving to Medium drops the average to 51 FPS, and High further reduces it to 43 FPS. This sensitivity to preset changes is a classic sign of GPU limitation. At 1440p, the Low preset averages 53 FPS, and at 4K it drops to 31 FPS. The frame rate scales almost linearly with the number of pixels, which is a hallmark of a GPU-bound scenario. The CPU has enough headroom to feed the GPU, but the GPU cannot process the frames quickly enough.

The Verdict

The question of whether this PC can run Rust has a conditional answer. Based on the recorded measurements, it can run the game, but with severe limitations. The verdict by resolution is unambiguous:

• 3840x2160: Not playable. No settings preset reaches 60 FPS.
• 2560x1440: Not playable. No settings preset reaches 60 FPS.
• 1920x1080: Playable only on the Low preset, which achieves an average of 76 FPS.

This combo is only viable for 1080p gaming with the lowest graphical settings. Any attempt to increase resolution or visual fidelity will result in frame rates well below the 60 FPS playable threshold. The data suggests a user would need to accept significant visual compromises for a smooth experience.

Measured FPS Breakdown

The following is the complete set of measured average frame rates, with minimum and maximum values where recorded.

3840x2160 (4K)

• Ultra: Average 13 FPS
• High: Average 18 FPS
• Medium: Average 21 FPS, Minimum 18 FPS, Maximum 24 FPS
• Low: Average 31 FPS

2560x1440 (1440p)

• Ultra: Average 23 FPS
• High: Average 30 FPS
• Medium: Average 35 FPS, Minimum 30 FPS, Maximum 41 FPS
• Low: Average 53 FPS

1920x1080 (1080p)

• Ultra: Average 33 FPS
• High: Average 43 FPS
• Medium: Average 51 FPS, Minimum 44 FPS, Maximum 59 FPS
• Low: Average 76 FPS

The data shows a consistent pattern: only the 1080p Low preset delivers a playable experience. The minimum FPS values for the Medium presets also confirm instability, with 1080p dipping to 44 FPS and 1440p dropping to 30 FPS. This combination is strictly for low-demand, low-resolution play.
