Doom

The Intel Core Ultra 7 265 and Intel Arc B390 pairing presents a highly unusual performance profile. The CPU is a high-end desktop processor, while the GPU is an integrated graphics solution based on the Xe3-LPG architecture. The measured data for Doom shows a system that is strictly limited by its graphics component, with performance dropping sharply as resolution increases.

Best Settings per Resolution

The benchmark data reveals clear performance ceilings for this configuration across the three tested resolutions. The most demanding preset that maintains an average of at least 60 FPS is the target for each resolution.

At 1920x1080, the system is capable of running the game at the Ultra preset with an average of 64 FPS. This is the highest visual quality setting available in the test suite, and it clears the 60 FPS playability threshold. The progression in performance at this resolution shows a steady decline as settings increase: Low produces 107 FPS, Medium produces 93 FPS, and High produces 78 FPS. All four presets at 1080p exceed the 60 FPS target, making this the only resolution where the full range of graphical options is available.

At 2560x1440, the situation changes considerably. The Medium preset is the most demanding option that stays at or above 60 FPS, achieving exactly 60 FPS on average. The Low preset runs faster at 69 FPS, but it is not the most demanding playable option. The High preset drops to 51 FPS, which falls below the playability threshold, and Ultra drops further to 41 FPS. The playable settings list for this resolution includes only Low and Medium.

At 3840x2160, no preset achieves the 60 FPS target. The best recorded result is the Low preset at 37 FPS, which is still well below playable. The data shows Medium at 33 FPS, High at 28 FPS, and Ultra at 22 FPS. The verdict for this resolution confirms that there are no playable settings, meaning the system cannot maintain 60 FPS at 4K under any tested configuration.

CPU and GPU Roles

The division of labor between the Intel Core Ultra 7 265 and the Arc B390 is stark. The CPU is a 20-core, 20-thread Arrow Lake processor with a boost clock of 5.30 GHz and a 93rd percentile ranking among all tested CPUs. The GPU, by contrast, sits in the 9th percentile of all tested GPUs, and its only recorded benchmark is a 3DMark Steel Nomad DX12 score of 1482. The bottleneck is unambiguous.

The scaling between resolutions confirms that the GPU is the limiting factor. At 1080p, the Ultra preset produces 64 FPS. Moving to 1440p, the same Ultra preset drops to 41 FPS, a reduction of roughly 36 percent. At 4K, Ultra falls to 22 FPS. Across the board, each step up in resolution produces a substantial loss in frame rate, which is the classic signature of a GPU-bound scenario.

Preset scaling reinforces this conclusion. At 1080p, the difference between Low and Ultra is 43 FPS (107 versus 64). At 1440p, the same comparison shows a 28 FPS gap (69 versus 41). At 4K, the gap narrows to 15 FPS (37 versus 22). As resolution increases, the absolute difference between presets shrinks because the GPU is already saturated by the pixel workload. The CPU has ample headroom at all resolutions; its Cinebench R23 multi-core score of 42216 and single-core score of 5960 place it far above the demands of a 2016 title like Doom.

The integrated nature of the Arc B390, which uses system shared memory and has a system dependent bandwidth, means it cannot scale with the CPU's capabilities. The CPU's dual-channel DDR5 memory support and 102.4 GB/s memory bandwidth are irrelevant when the GPU is the constraint. The data shows that no combination of CPU performance can compensate for the GPU's limits at higher resolutions.

FAQ

Q: Can this PC run Doom at 4K?

A: No. The verdict for 3840x2160 lists no playable settings. The best average frame rate at 4K is 37 FPS on Low settings, which falls below the 60 FPS playability threshold.

Q: What is the best settings preset for 1440p?

A: The Medium preset is the most demanding option that stays at or above 60 FPS, with an average of exactly 60 FPS. Low also clears the threshold at 69 FPS, but Medium offers higher visual quality while remaining playable.

Q: Is the CPU or GPU the limiting factor?

A: The GPU is the limiting factor. The CPU ranks in the 93rd percentile of all tested CPUs, while the GPU ranks in the 9th percentile. Frame rates drop sharply with each resolution increase, a pattern consistent with GPU-bound performance.

Q: What frame rate does the Ultra preset achieve at 1080p?

A: The Ultra preset averages 64 FPS at 1920x1080. This is above the 60 FPS playability threshold, making Ultra the recommended setting for that resolution.

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

A: The Arc B390's average benchmark score is 1482. It is 1.3 percent ahead of the NVIDIA GeForce GT 520MX, 1.5 percent ahead of the NVIDIA GeForce 800M, 2.5 percent ahead of the NVIDIA GeForce GT 625 OEM, and 2.7 percent ahead of the NVIDIA GeForce GT 710.

Q: Which resolutions are fully playable with this configuration?

A: Only 1920x1080 has all four presets above 60 FPS. At 2560x1440, only Low and Medium are playable. At 3840x2160, no preset reaches 60 FPS.

Similar Performance Alternatives

The nearest rivals for the CPU and GPU provide context for how this combination compares to other hardware. The Intel Core Ultra 7 265 has an average benchmark score of 64640. Its closest competitor is the AMD EPYC 4464P with an average score of 64823, which is 0.3 percent ahead. The Intel Core Ultra 7 265F is 0.3 percent behind this chip with a score of 64438. The AMD EPYC 7343 scores 64202, which is 0.7 percent behind, and the AMD EPYC 9124 scores 65104, which is 0.7 percent ahead. These deltas are all within one percent, meaning any of these CPUs would deliver nearly identical CPU-bound performance in this game.

The GPU side is far more constrained. The Intel Arc B390 has an average benchmark score of 1482. Its nearest rival is the NVIDIA GeForce GT 520MX at 1463, which is 1.3 percent slower. The NVIDIA GeForce 800M scores 1460, 1.5 percent slower. The NVIDIA GeForce GT 625 OEM scores 1446, 2.5 percent slower. The NVIDIA GeForce GT 710 scores 1443, 2.7 percent slower. All four rival GPUs are within roughly three percent of the Arc B390's performance, so swapping to any of them would produce similar frame rates in Doom. The practical takeaway is that this GPU sits at the very bottom of the performance spectrum, and its rivals are all entry-level or legacy parts.

The Verdict

The data answers the question directly. This PC can run Doom, but only under specific conditions. At 1920x1080, the system clears the 60 FPS threshold on all four presets, with Ultra averaging 64 FPS. At 2560x1440, the system is playable on Low and Medium, with Medium averaging exactly 60 FPS. At 3840x2160, no preset reaches 60 FPS; the best result is 37 FPS on Low.

The verdict by resolution states that 1080p supports High, Low, Medium, and Ultra as playable settings. The 1440p resolution supports only Low and Medium. The 4K resolution supports no playable settings. For a game like Doom, which is not particularly demanding by modern standards, this configuration delivers acceptable performance only at 1080p. Gamers targeting 1440p must accept Medium settings, and 4K is entirely out of reach. The combination of a high-end CPU and an entry-level integrated GPU creates a system that is only suitable for 1080p gaming in this title.

How This Combo Ranks

The combined rank for this CPU and GPU pairing in Doom is 3300 out of 3712 tested combinations. This places the configuration in the bottom 11 percent of all tested combos, which is consistent with the GPU's 9th percentile ranking. The CPU's 93rd percentile ranking does not meaningfully improve the overall position because the GPU dictates the frame rates in this game.

The ranking reflects the measured reality of the benchmark results. A system with a top-tier CPU and a bottom-tier GPU will rank poorly in GPU-bound scenarios, and Doom is exactly that. The 3300 rank out of 3712 combos suggests that most other tested configurations, even those with much weaker CPUs, outperform this pairing because they include more capable graphics hardware. The data shows that this combination is best suited for 1080p gaming at high settings, with no headroom for higher resolutions or more demanding future titles.
