Doom

The Intel Core Ultra 7 265K and Intel Arc B580 combination delivers a playable Doom experience at 1080p and 1440p with maximum settings, but 4K requires dropping to Low to stay above 60 FPS. Measured results show average frame rates ranging from 40.8 FPS at 4K Ultra to 186.9 FPS at 1080p Low. The CPU’s strong multi-core performance (Cinebench R23 multi-core 35850) and the GPU’s mid-range standing (68th percentile among all GPUs) shape this outcome. The combo ranks 2824th out of 3712 tested configurations, placing it in the lower third of the field.

Similar Performance Alternatives

The Intel Core Ultra 7 265K’s average benchmark score of 70879 puts it in the 94th percentile among all CPUs. Its nearest rivals, based on average score, are the Intel Xeon 6511P (71051, 0.2% lower), Intel Xeon Platinum 8270 (71370, 0.7% lower), Intel Core i7-14700KF (70163, 1% higher), and AMD Ryzen 7 9700F (69996, 1.3% higher). In CPU-bound scenarios, any of these processors would deliver nearly identical frame rates in Doom. However, Doom’s engine is heavily GPU-dependent, so the CPU choice matters less than the GPU in most situations. The 265K’s 20 cores and 20 threads, along with its 30 MB of L3 cache, provide ample headroom for the game’s logic, but the measured FPS data indicates that the GPU is the primary constraint.

For the GPU, the Intel Arc B580 posts an average benchmark score of 23021, which lands it in the 68th percentile of all GPUs. Its nearest rivals are the AMD Radeon RX 580 2048SP (23061, 0.2% lower), NVIDIA GeForce RTX 2080 (22895, 0.6% higher), NVIDIA GeForce RTX 3080 (23172, 0.7% lower), and NVIDIA P106-100 (23249, 1% lower). These GPUs would produce very similar frame rates in Doom. The B580’s 12 GB of GDDR6 memory and 456.0 GB/s bandwidth are ample for this 2016 title, and its 2560 shading units and 80 ROPs align with the mid-range segment. The launch MSRP of the B580 is 249 USD, positioning it as a mainstream option, though pricing is not a factor in the performance analysis.

CPU and GPU Roles

The measured FPS data across resolutions and presets reveals how the workload shifts between CPU and GPU. At 1920x1080, the average frame rate ranges from 186.9 FPS on Low to 111.3 FPS on Ultra. That is a 75.6 FPS spread, indicating that the GPU is still the primary constraint because lowering graphical settings directly increases throughput. The CPU, with its Cinebench R23 single-core score of 2020 and multi-core score of 35850, has ample headroom; it can feed the GPU without bottlenecking even at high frame rates. At 1080p Low, the 186.9 FPS average is well beyond the 60 FPS playable threshold, confirming that the CPU is not a limiting factor.

Moving to 2560x1440, the same preset sweep yields 119.4 FPS (Low) down to 69.7 FPS (Ultra). The absolute numbers drop, but the relative scaling remains consistent. At 3840x2160, the picture changes: Low averages 63.6 FPS, Medium 57.2, High 49.7, and Ultra 40.8. The gap between Low and Ultra is only 22.8 FPS, compared to 75.6 at 1080p. This compressed scaling at 4K indicates that the GPU is saturated; the pixel throughput becomes the dominant cost, and the CPU’s role diminishes further. In short, the Arc B580 is the decisive component in this pairing. The Core Ultra 7 265K is more than sufficient for Doom, and its performance would only become relevant if paired with a much faster GPU or at extremely high refresh rates where CPU overhead could matter. The data shows that at every resolution, the frame rate scales inversely with resolution, confirming a GPU-bound workload.

Measured FPS Breakdown

The following table lists the measured average frame rates for every resolution and preset combination. Minimum and maximum frame rates were not recorded in the data set.

| Resolution | Settings | Average FPS |

|------------|----------|-------------|

| 3840x2160 | High | 49.7 |

| 3840x2160 | Low | 63.6 |

| 3840x2160 | Medium | 57.2 |

| 3840x2160 | Ultra | 40.8 |

| 2560x1440 | High | 88.6 |

| 2560x1440 | Low | 119.4 |

| 2560x1440 | Medium | 101.4 |

| 2560x1440 | Ultra | 69.7 |

| 1920x1080 | High | 132.7 |

| 1920x1080 | Low | 186.9 |

| 1920x1080 | Medium | 161.8 |

| 1920x1080 | Ultra | 111.3 |

At 1080p, every preset exceeds the 60 FPS playable threshold, with even the most demanding Ultra setting averaging 111.3 FPS. The spread from Low to Ultra is 75.6 FPS, meaning that the GPU’s performance headroom allows for a wide range of visual fidelity without sacrificing playability. At 1440p, Ultra still clears 60 FPS at 69.7, but High and Medium are more comfortable at 88.6 and 101.4 respectively. The drop from 1080p to 1440p is roughly 25% across all settings, consistent with the increased pixel count. At 4K, only Low reaches 63.6 FPS; Medium, High, and Ultra fall below 60. The data shows a clear progression: the B580’s 13.67 TFLOPS FP32 throughput and 456.0 GB/s memory bandwidth are sufficient for high-refresh 1080p and solid 1440p, but 4K demands the lowest settings to maintain playability.

How This Combo Ranks

The Intel Core Ultra 7 265K and Intel Arc B580 combination ranks 2824th out of 3712 tested combos in Doom. This places it in the lower third of the field (approximately the 24th percentile from the top, since 888 combos are worse). The rank reflects the B580’s mid-range GPU performance; the CPU’s 94th percentile standing does not boost the combo because Doom is GPU-limited. To improve the rank, a faster GPU would be required. The measured data shows that the combo is capable of 60+ FPS at 1080p and 1440p with maximum settings, but it struggles at 4K, which is consistent with its rank. The B580’s nearest GPU rivals—such as the RTX 3080, which scores 0.7% higher—would likely push the combo to a higher rank, but the 265K’s contribution is minimal in this title.

Best Settings per Resolution

Based on the 60 FPS playable threshold, the best settings for each resolution are the highest preset that maintains an average of at least 60 FPS.

• 1920x1080: Ultra is playable with an average of 111.3 FPS. This is the most demanding preset and remains far above the threshold.
• 2560x1440: Ultra is also playable here, averaging 69.7 FPS. It clears the 60 FPS line, though with less headroom than at 1080p.
• 3840x2160: Only Low reaches 60 FPS, with an average of 63.6 FPS. Medium, High, and Ultra all fall below 60.

These recommendations come directly from the measured data. Players seeking higher visual fidelity at 4K would need to accept sub-60 frame rates or rely on upscaling technologies, which are not covered in this data set. The combination of the Core Ultra 7 265K and Arc B580 delivers a smooth experience at mainstream resolutions, but 4K remains a challenge unless settings are dialed back to the minimum.
