How This Combo Ranks

The Intel Core i7-12700KF paired with the Intel Arc B390 ranks 3312th out of 3723 tested combinations in Rust. That places this build in the bottom 11% of the database for this game, which is a poor result for a desktop CPU that sits in the 85th percentile among all processors. The discrepancy between CPU strength and overall gaming performance points directly to the graphics solution as the limiting factor.

The Arc B390 is an integrated graphics part, drawing up to 80 watts, and its benchmark standing reflects that. It scores in the 9th percentile of all GPUs, meaning roughly 9 out of every 10 graphics cards in the database outperform it in synthetic workloads. Its only recorded benchmark, 3DMark Steel Nomad DX12, returns a score of 1482. For context, its nearest rivals in the GPU rankings are the GT 520MX (1463, 1.3% slower), the GeForce 800M (1460, 1.5% slower), the GT 625 OEM (1446, 2.5% slower), and the GT 710 (1443, 2.7% slower). All of these are low-end or legacy parts, and the Arc B390 is only marginally ahead of them, never more than 2.7%. This is not a card built for modern gaming workloads.

The CPU, meanwhile, is a 12-core, 20-thread Alder Lake-S processor with a base clock of 3.60 GHz and a boost of 5.00 GHz. Its Cinebench R23 multi-core score of 28,838 and single-core score of 4,071 rank it well above the typical gaming CPU threshold. Its nearest CPU rivals include the Core i7-13700T (35,403 average, 0.1% slower), the Core 5 213PE (35,428, 0.2% slower), the Core i5-13600T (35,305, 0.2% faster), and the Core i7-12700K (35,287, 0.2% faster). The deltas are tiny, so any of these CPUs would behave nearly identically in Rust. The data shows that the processor is not the constraint here.

Because the GPU is so far down the rankings, the overall combo rank is dragged down. The CPU alone would place this build in the top 15% of processors, but the GPU alone places it in the bottom 9% of graphics cards. The combination rank of 3312 out of 3723 tells you that this system is only a little above the worst 11% of all tested combos. In practical terms, this is a machine that can run the game, but only at the lowest settings and only at 1080p, and even then with no headroom.

FAQ

Q: Can this PC run Rust at 60 FPS at any resolution?

A: Yes, but only at 1920x1080 with Low settings. The measured average FPS there is 76. No other resolution or preset combination reaches 60 FPS. At 1440p, the best case is Low settings at 53 FPS, and at 4K the best case is Low at 31 FPS.

Q: How does the GPU compare to its closest rivals?

A: The Arc B390 outperforms the GT 520MX by 1.3%, the GeForce 800M by 1.5%, the GT 625 OEM by 2.5%, and the GT 710 by 2.7% in the 3DMark Steel Nomad DX12 test. These deltas are small, so any of these GPUs would deliver similar frame rates in Rust.

Q: Is the CPU strong enough for this game?

A: The Core i7-12700KF is in the 85th percentile of all CPUs, with a Cinebench R23 multi-core score of 28,838 and a single-core score of 4,071. Its nearest rival, the Core i7-12700K, is only 0.2% faster, so the CPU is more than capable for Rust. The bottleneck is clearly the integrated GPU.

Q: What is the best preset at 1440p?

A: The best preset at 2560x1440 is Low, with an average of 53 FPS. Medium drops to 35, High to 30, and Ultra to 23. None of these hit the 60 FPS threshold.

Q: What is the best preset at 4K?

A: The best preset at 3840x2160 is Low, with an average of 31 FPS. Medium averages 21, High averages 18, and Ultra averages 13. All are far below playable.

Q: Are there any settings that are close to 60 FPS at 1080p besides Low?

A: No. At 1080p, Medium averages 51 FPS, High averages 43, and Ultra averages 33. Only Low reaches above 60 FPS, with 76 FPS. The next closest is 51, which is a 9 FPS gap.

CPU and GPU Roles

The data shows a clear pattern: the GPU is the limiting hardware in every scenario. The CPU has a multi-core score of 28,838 in Cinebench R23, which is far more than Rust needs. The GPU, meanwhile, produces only 1,482 in 3DMark Steel Nomad DX12, which places it below the 10th percentile of all GPUs. When a system has this kind of CPU-to-GPU imbalance, the frame rate is almost entirely dependent on the graphics card.

At 1080p, the scaling across presets shows how the GPU struggles. Low settings produce 76 FPS, Medium 51 FPS (44 min, 59 max), High 43 FPS, and Ultra 33 FPS. The drop from Low to Medium is 25 FPS, from Medium to High is 8 FPS, and from High to Ultra is 10 FPS. These are large relative drops for preset changes, which indicates that the shading, texture, and effects load quickly overwhelms the GPU. The CPU could handle any of these presets without breaking a sweat.

At 1440p, the same pattern continues but with lower absolute numbers. Low gives 53 FPS, Medium gives 38 (30 min, 41 max), High gives 30, and Ultra gives 23. The gap between Low and Medium is 15 FPS, between Medium and High is 8 FPS, and between High and Ultra is 7 FPS. The GPU is already at its limits at Low settings in this resolution.

At 4K, the GPU is completely overwhelmed. Low gives 31 FPS, Medium gives 21 (18 min, 24 max), High gives 18, and Ultra gives 13. The differences between presets shrink to 10 FPS or less, because the pixel count alone is enough to saturate the GPU. The CPU has no effect here; the data shows that no matter what preset is chosen, the GPU cannot push past the low 30s.

The role of the CPU only becomes noticeable if you compare this system to a similar one with a weaker processor. But in the database, the CPU is not the limiting factor at any resolution. The recorded FPS numbers at every preset and resolution are consistent with a GPU bound scenario, where the graphics hardware determines the frame rate.

The Verdict

The verdict by resolution is straightforward. At 3840x2160, there are no playable settings. The best average is 31 FPS at Low, which is far below the 60 FPS threshold. At 2560x1440, there are no playable settings either. The best average is 53 FPS at Low, which is 7 FPS short of the target. At 1920x1080, the only playable preset is Low, with an average of 76 FPS. The best settings at 1080p are Low, and the average FPS at that preset is 76.

So this PC can run Rust, but with a major caveat: you must play at 1080p and use the Low preset. That is the only configuration that clears 60 FPS. If you want to run Medium or higher at 1080p, you will see averages between 33 and 51 FPS, which are below the playable threshold. At 1440p or 4K, the system cannot achieve 60 FPS at any preset, including Low.

The data suggests that this is a system built for productivity or light tasks, not for gaming. The CPU is strong enough for any game, but the integrated GPU is not. For Rust, the verdict is: playable at 1080p Low, not playable at any other resolution or setting.

Measured FPS Breakdown

The database logs show FPS measurements for three resolutions and four presets each, for a total of 12 data points.

3840x2160 (4K):

• Low: average 31 FPS
• Medium: average 21 FPS, min 18, max 24
• High: average 18 FPS
• Ultra: average 13 FPS

2560x1440 (1440p):

• Low: average 53 FPS
• Medium: average 38 FPS, min 30, max 41
• High: average 30 FPS
• Ultra: average 23 FPS

1920x1080 (1080p):

• Low: average 76 FPS
• Medium: average 51 FPS, min 44, max 59
• High: average 43 FPS
• Ultra: average 33 FPS

The min and max figures are only recorded for Medium presets across all resolutions. At Medium 1080p, the range is 44 to 59 FPS, which means the game can dip almost to 44 FPS during heavy scenes, confirming that even this preset is not stable. At Medium 1440p, the range is 30 to 41, and at Medium 4K, the range is 18 to 24. These ranges are tight, which indicates that the GPU is consistently saturated rather than stuttering.

The progression from Low to Ultra at each resolution shows the GPU’s scaling. At 1080p, Low (76) to Ultra (33) is a 43 FPS drop. At 1440p, Low (53) to Ultra (23) is a 30 FPS drop. At 4K, Low (31) to Ultra (13) is an 18 FPS drop. The delta shrinks as resolution increases because the GPU is already at its limit at Low settings, so turning up the presets has less headroom to lose.

Best Settings per Resolution

The best settings are defined as the most demanding preset that stays at or above 60 FPS on average. Based on the recorded data:

• 3840x2160: No preset averages 60 FPS. The highest average is 31 FPS at Low, so there is no playable setting at this resolution.
• 2560x1440: No preset averages 60 FPS. The highest average is 53 FPS at Low, which is still 7 FPS short of the threshold.
• 1920x1080: Low settings are the only preset that reaches 60 FPS, with an average of 76 FPS. Medium drops to 51 FPS, so it is not playable.

If you want to play Rust on this system, you have exactly one option: 1080p, Low settings. At this configuration, the average FPS is 76, which provides some margin above the 60 FPS threshold, but the data shows that this margin is not massive. The game will likely dip below 60 FPS in heavy scenes, though the database does not record min FPS for Low presets. The only min FPS data we have is for Medium at 1080p (44 min), which shows that the GPU can struggle in real-time loads.

Similar Performance Alternatives

If you are considering this CPU and GPU combo, the database shows that you might also look at other parts that deliver nearly identical performance.

For the CPU, the Core i7-13700T has an average score of 35,403, which is 0.1% faster than the i7-12700KF. The Core 5 213PE is 0.2% faster (35,428), the Core i5-13600T is 0.2% faster (35,305), and the Core i7-12700K is 0.2% faster (35,287). These are all within a fraction of a percent, so if you have a motherboard that supports any of them, you would see no meaningful difference in Rust. The CPU is not a bottleneck in any of these configurations.

For the GPU, the nearest rivals are all older NVIDIA parts. The GT 520MX is 1.3% faster than the Arc B390, the GeForce 800M is 1.5% faster, the GT 625 OEM is 2.5% faster, and the GT 710 is 2.7% faster. These are all extremely close in performance, so if you have any of these GPUs, your frame rates in Rust will be within a few FPS of the B390. The data shows that they are all equally unsuited for this game at high settings.

If you were to combine a weaker CPU with the same GPU, the overall rank would change, but the game performance would likely remain similar because the GPU is the limiting factor. Conversely, if you pair this CPU with a stronger GPU, the FPS would increase substantially, but that is outside the scope of this page. For this specific combo, the CPU is overkill, and the GPU is underpowered. The database records no other component that behaves differently for Rust. The only takeaway is that the GPU is the decisive hardware, and it is far too weak for any preset above Low at 1080p.
