Rust

Intel Core i7-14700F and Intel Arc B390 in Rust: this pairing represents a massive mismatch in raw compute potential. The CPU is a high-end 20-core part that sits in the 91st percentile of all processors, while the GPU is an integrated-class solution that ranks in the 9th percentile of all graphics cards. The recorded data shows that the Arc B390 becomes the overwhelming bottleneck at every resolution, reducing what should be a highly capable gaming platform into a low-end experience. The benchmark results tell a clear story of GPU-bound performance collapse, where even the strongest CPU settings cannot compensate for the graphics card's limitations.

Measured FPS Breakdown

At 3840x2160, the highest resolution tested, the Arc B390 delivers severely constrained frame rates across all four presets. At High settings, the average FPS is 18. Low settings improve this to an average of 31 FPS. Medium settings produce an average of 21 FPS, with a recorded minimum of 18 and maximum of 24. Ultra settings drop further to an average of 13 FPS. None of these figures approach the 60 FPS playability threshold, and the spread between Low and Ultra represents a 18 FPS swing, confirming that the GPU has almost no headroom at 4K.

Moving to 2560x1440, the situation improves but remains far from playable. High settings average 30 FPS. Low settings reach an average of 53 FPS, which is the best result at this resolution but still 7 FPS short of the 60 FPS target. Medium settings average 35 FPS, with a minimum of 30 and maximum of 41. Ultra settings average 23 FPS. The gap between Low and Ultra here is 30 FPS, showing that the GPU's limited shading units and texture units scale poorly with increased graphical load.

At 1920x1080, the data finally shows a playable configuration. Low settings achieve an average of 76 FPS, clearing the 60 FPS threshold by 16 frames. High settings average 43 FPS, Medium averages 51 FPS with a minimum of 44 and maximum of 59, and Ultra averages 33 FPS. The Medium preset's maximum of 59 FPS is notable, as it sits just 1 FPS below the playability target, but the average remains below 60. The 1080p results demonstrate that only the Low preset can sustain consistent frame rates above the threshold, while every other setting falls short.

CPU and GPU Roles

The data clearly indicates that the Intel Arc B390 is the dominant performance limiter in this pairing. Across all three resolutions, the frame rate scales almost entirely with GPU workload rather than CPU capability. The i7-14700F, with its 20 cores and 28 threads, is never the constraining factor in Rust. The CPU's benchmark scores, including a Cinebench R23 multi-core score of 35122 and a single-core score of 4958, place it far above what any modern game would require for basic scene management.

The resolution scaling confirms this analysis. From 1080p Low at 76 FPS to 1440p Low at 53 FPS, the drop is 23 FPS, a 30% reduction. From 1440p Low to 4K Low at 31 FPS, the drop is another 22 FPS, a 41% reduction. These percentage losses are characteristic of a GPU that is running out of fillrate and shading capacity, not a CPU that is struggling with draw calls or physics calculations. If the CPU were the bottleneck, the frame rate would remain relatively flat across resolutions, since the CPU work does not increase proportionally with pixel count.

The preset scaling further reinforces this conclusion. At 1080p, moving from Low to High reduces the average from 76 to 43 FPS, a 43% performance loss. At 1440p, the same preset change drops from 53 to 30 FPS, a 43% loss. At 4K, it drops from 31 to 18 FPS, a 42% loss. This consistent percentage decrease across all resolutions indicates that the GPU's shading units, TMUs, and ROPs are saturated at every setting level. The i7-14700F's role is limited to feeding frames to the GPU, and with a PassMark single-thread score of 4257, it has ample capacity to do so.

Best Settings per Resolution

At 3840x2160, the recorded data shows no playable settings. Every preset, from Low at 31 FPS to Ultra at 13 FPS, falls below the 60 FPS threshold. The best possible average FPS at 4K is 31 on Low, but this is still less than half of the playability target. The verdict data confirms this, listing no playable settings for this resolution.

At 2560x1440, the situation is identical. No preset achieves 60 FPS. The best result is Low settings at 53 FPS, which is 7 FPS short of the threshold. Medium at 35 FPS, High at 30 FPS, and Ultra at 23 FPS all fall further behind. The verdict data again lists no playable settings for 1440p.

At 1920x1080, the Low preset is the only playable option. It delivers an average of 76 FPS, which is 16 FPS above the 60 FPS target. This is the most demanding preset that stays at or above 60 FPS at this resolution. The Medium preset comes close with an average of 51 FPS and a maximum of 59, but its average falls below the threshold. High at 43 FPS and Ultra at 33 FPS are not viable for smooth gameplay. The verdict data confirms Low as the best settings at 1080p, with an average FPS of 76.

Q: What is the best performance this combo can achieve at 1440p?

A: The best result at 2560x1440 is 53 FPS on Low settings. This is 7 FPS short of the 60 FPS target. Medium settings average 35 FPS, High settings average 30 FPS, and Ultra settings average 23 FPS. No preset at 1440p reaches the playability threshold.

Q: Is the Intel Core i7-14700F the bottleneck in this system?

A: No, the data indicates the Intel Arc B390 is the limiting component. The CPU's benchmark scores place it in the 91st percentile of all processors, while the GPU sits in the 9th percentile. The frame rate drops consistently across resolutions and presets, which is characteristic of GPU saturation rather than CPU limitations.

Q: How does this combo compare to other tested combinations in the database?

A: The combo ranks 3312 out of 3723 tested combinations, placing it in the bottom 11% of all pairings. This low rank is driven by the GPU's weak performance, as the CPU is capable of much higher frame rates when paired with a stronger graphics card.

Q: What settings should be used for the best visual quality while staying above 60 FPS?

A: At 1080p, Low settings is the only preset that stays above 60 FPS. Medium settings nearly reach the target with a maximum of 59 FPS but average 51 FPS. For resolutions above 1080p, no settings achieve 60 FPS, so users must lower the resolution to 1080p and use Low settings.

Q: How much faster is Low settings compared to Ultra at 1080p?

A: At 1920x1080, Low settings average 76 FPS while Ultra settings average 33 FPS. This represents a 43 FPS difference, meaning Low settings are more than twice as fast. The gap widens at higher resolutions, with a 31 FPS difference at 1440p and an 18 FPS difference at 4K.

How This Combo Ranks

The combination of the Intel Core i7-14700F and Intel Arc B390 ranks 3312 out of 3723 tested combos in Rust. This places it in the 11th percentile of all tested system pairings, meaning that roughly 89% of combinations deliver better performance in this game. The rank is driven almost entirely by the GPU, as the i7-14700F's own percentile rank of 91 puts it in the top 10% of CPUs, while the Arc B390's percentile rank of 9 puts it in the bottom 10% of GPUs.

The disparity between the two components is stark. The CPU's average benchmark score of 53620 is more than 36 times higher than the GPU's average score of 1482. This imbalance means that the system's performance in Rust is effectively capped by the GPU, and any other CPU in the same performance class would produce nearly identical results. The recorded frame rates show that the system cannot reach 60 FPS at 1440p or 4K under any settings, and at 1080p only the Low preset achieves playable performance.

For users considering this pairing, the data suggests that the i7-14700F is severely underutilized when paired with the Arc B390. The CPU's capabilities, including its 20 cores, 28 threads, and 33 MB of L3 cache, are far beyond what Rust requires when the GPU can only produce 76 FPS at 1080p Low. The system's overall rank of 3312 reflects this waste of CPU potential, as the same processor paired with a mid-range discrete GPU would likely rank substantially higher. The Arc B390 is the definitive performance ceiling for this combination.
