Undisputed

Measured FPS Breakdown

The recorded data for Undisputed with the Intel Core i5-9400 and Intel Arc B390 shows a wide performance spread across the three tested resolutions and four quality presets. At 1920x1080, the combination delivers its strongest results. Low settings produce an average of 127 FPS, Medium averages 91 FPS with a minimum of 78 FPS and a maximum of 105 FPS, and High averages 76 FPS. Ultra is the only preset at this resolution that falls short of the 60 FPS playability threshold, averaging 49 FPS.

Moving to 2560x1440, the performance drops are noticeable but the combination remains playable on the lighter presets. Low averages 92 FPS, Medium averages 66 FPS with a minimum of 56 FPS and a maximum of 76 FPS, and High averages 55 FPS. Ultra at 1440p averages 35 FPS, which is a substantial step down from the Medium result.

At 3840x2160, the Intel Arc B390 is clearly overextended. Low averages 58 FPS, Medium averages 42 FPS with a minimum of 36 FPS and a maximum of 48 FPS, High averages 35 FPS, and Ultra averages 22 FPS. No preset at 4K reaches the 60 FPS target, and even the Low preset falls just short of it. The data shows a consistent pattern: each resolution jump costs a significant portion of the average frame rate, and each preset increase at the same resolution reduces the average further. The gap between Low and Ultra at 1080p is 78 FPS, at 1440p it is 57 FPS, and at 2160p it is 36 FPS, indicating that preset scaling has a larger absolute impact at lower resolutions.

Best Settings per Resolution

At 1920x1080, the best settings that maintain at least 60 FPS average are High, which produces an average of 76 FPS. This is the most demanding preset that clears the threshold, and it leaves a modest cushion above the 60 FPS line. Medium and Low also clear the threshold, but High offers the best visual quality among the playable options.

At 2560x1440, the best settings are Medium, which averages 66 FPS. Low also clears the threshold at 92 FPS, but Medium provides a better visual balance while still staying above 60 FPS. High at this resolution averages 55 FPS, so it cannot be recommended for a smooth experience.

At 3840x2160, there are no playable settings. The closest result is Low at 58 FPS, which misses the 60 FPS target by a small margin. Medium, High, and Ultra all fall further behind, so the database records no best settings for this resolution. The conclusion is straightforward: 4K is not viable for this combination in Undisputed, while 1080p and 1440p both offer at least one preset that clears the playability bar.

How This Combo Ranks

The Intel Core i5-9400 and Intel Arc B390 combination ranks 3304 out of 3718 tested combos in Undisputed. That places it in the lower portion of the database, with roughly 89 percent of tested combinations performing better. The CPU itself sits at the 47th percentile among all CPUs in the database, and its average benchmark score of 2254 places it very close to several direct rivals. The Intel Core i7-1068NG7 scores 2259, which is 0.2 percent higher, while the Intel Core i3-10305 scores 2264, 0.4 percent higher. On the other side, the Intel Core i7-10710U scores 2248, 0.3 percent lower, and the AMD Ryzen 5 PRO 1500 scores 2246, 0.4 percent lower. These deltas are tiny, so the CPU is essentially performance-neutral compared with its closest peers.

The GPU tells a different story. The Intel Arc B390 sits at the 9th percentile among all GPUs, and its only recorded benchmark, 3DMark Steel Nomad DX12, yields a score of 1482. Its nearest rivals are all older NVIDIA parts: the GeForce GT 520MX scores 1463, 1.3 percent lower; the GeForce 800M scores 1460, 1.5 percent lower; the GeForce GT 625 OEM scores 1446, 2.5 percent lower; and the GeForce GT 710 scores 1443, 2.7 percent lower. The Arc B390 leads this group, but the margin is narrow and the overall performance class is low. In game-specific terms, the combo rank of 3304 out of 3718 reflects the GPU's position as the dominant constraint, since the CPU is a mid-pack part while the GPU is near the bottom of the database.

Q: Which component limits performance more in Undisputed?

A: The GPU is the limiting factor. The Arc B390 sits at the 9th percentile among all GPUs and its nearest rivals are all low-end NVIDIA parts, while the CPU sits near the 50th percentile with very small deltas to its nearest rivals. The FPS scaling across resolutions also points to GPU-bound behavior.

CPU and GPU Roles

The benchmark results show a system that is heavily GPU-bound in Undisputed. The CPU, Intel Core i5-9400, is a 6-core, 6-thread part with a base clock of 2.90 GHz and a boost clock of 4.10 GHz. Its average benchmark score of 2254 and its 47th percentile ranking mean it sits in the middle of the database, and its nearest rivals are within a fraction of a percent of its score. That kind of parity suggests the CPU is not the deciding factor in this game's performance.

The Intel Arc B390, by contrast, sits at the 9th percentile among all GPUs, with an average benchmark score of 1482. Its nearest rivals are all older, low-end NVIDIA parts, and while it leads them by margins of 1.3 to 2.7 percent, it is still in a very low performance class. The game data reinforces this. At 1920x1080, the difference between Low and Ultra is 78 FPS, and the difference between 1080p Low and 1440p Low is 35 FPS. The delta between 1440p Low and 2160p Low is 34 FPS. These are large swings that track with the GPU's rendering load, not with CPU throughput.

The CPU's role becomes even less prominent when looking at the preset scaling. At 1080p, the Ultra preset averages 49 FPS, which is below the 60 FPS threshold, while the same CPU with a stronger GPU would likely push that number much higher. The recorded data shows that the Arc B390's compute resources, 1536 shading units, 48 TMUs, and 24 ROPs, are simply not enough to feed the i5-9400's processing capacity at demanding settings. The CPU is capable of keeping up, but the GPU cannot translate that capability into high frame rates.

Resolution scaling tells the same story. The i5-9400's performance does not change with resolution, but the game's average FPS drops by roughly 35 to 40 percent between 1080p and 1440p, and again between 1440p and 2160p at the same preset. That is classic GPU-bound behavior. The CPU is effectively idle relative to the GPU's workload, and the system's playability is dictated almost entirely by the Arc B390's fill rate and shading throughput.

The one area where the CPU could matter more is at the very lowest settings, where the GPU load drops and frame rates rise. At 1080p Low, the system averages 127 FPS, which is high enough that CPU overhead could become relevant, but the i5-9400's strong single-thread score of 935 in Cinebench R23 suggests it can handle this load without becoming a bottleneck. The data does not show any CPU-related frame pacing issues, and the min/max values recorded at Medium presets, such as 78 to 105 FPS at 1080p and 56 to 76 FPS at 1440p, are consistent with a stable GPU-driven experience.

The Verdict

The Intel Core i5-9400 and Intel Arc B390 can run Undisputed, but only at certain resolutions and presets. At 1920x1080, the system clears the 60 FPS threshold on High, Medium, and Low settings, with High averaging 76 FPS. That is the recommended way to play: 1080p High delivers a solid average with room to spare. Medium at 1080p averages 91 FPS and Low averages 127 FPS, both of which are also fully playable, but Ultra at 49 FPS should be avoided.

At 2560x1440, the system remains playable on Medium, which averages 66 FPS, and Low, which averages 92 FPS. High at 55 FPS and Ultra at 35 FPS fall short of the 60 FPS target. For users with a 1440p display, Medium is the best choice because it balances visual quality with a playable frame rate.

At 3840x2160, the system cannot reach 60 FPS on any preset. Low averages 58 FPS, which is close but still below the threshold, and every other preset is further behind. The verdictByResolution data confirms this: no playable settings are recorded at 4K. Ultimately that this PC is a 1080p and 1440p machine for Undisputed, with 1080p High and 1440p Medium as the highest quality settings that maintain a smooth experience.
