Doom

The Intel Core Ultra 7 265K paired with the Intel Arc B580 presents a compelling, if unconventional, combination for running Doom. The data shows a system that excels at high refresh rates in 1080p and remains very playable at 1440p, but it demands careful settings management at 4K. This analysis breaks down the measured performance, component roles, and how to get the most out of this specific hardware configuration.

FAQ

*Q: What is the best resolution to use with this CPU and GPU combo for Doom?*

A: The sweet spot is 2560x1440. At this resolution, the system delivers 88.6 FPS on High settings and 119.4 FPS on Low, providing an excellent balance between visual fidelity and smooth, responsive gameplay. 1920x1080 is the only resolution that pushes past 132 FPS on High, while 3840x2160 struggles to maintain a consistent 60 FPS on any preset.

Q: How does the Ultra preset compare to the High preset at 1920x1080?

A: The performance cost is significant. The measured average frame rate drops from 132.7 FPS on High to 111.3 FPS on Ultra. This represents a clear trade-off: you gain the highest visual quality but lose over 20 FPS, which could be noticeable on a high-refresh-rate monitor.

*Q: Is this combo capable of 4K gaming in Doom?*

A: Yes, but with limitations. At 3840x2160, the best result is 63.6 FPS on Low settings. Choosing High drops the average to 49.7 FPS, and Ultra falls to 40.8 FPS. For a smooth 4K experience, you must stick to Low or Medium presets, and even then, frame times may not be perfectly consistent.

Q: How does the CPU's multi-core performance position it against its closest rivals?

A: The Intel Core Ultra 7 265K is extremely competitive. It is only 0.2% behind the Intel Core Ultra 7 265KF and the Intel Core i9-14900KF in average benchmark score. It also trails the Intel Core i9-14900K by just 0.9% and the AMD EPYC 7413 by 1.2%, indicating near-parity with top-tier desktop processors from the previous generation.

Q: What is the GPU's standing relative to other graphics cards in the database?

A: The Intel Arc B580 sits in the 66th percentile of all GPUs. Its average benchmark score is 23,021, which places it within 0.7% of the NVIDIA GeForce RTX 4060 and 1.3% ahead of the RTX 4060 Mobile. It also marginally outperforms the AMD Radeon 760M by 0.1%.

Q: Does the CPU hold back the GPU in this game?

A: The data suggests the CPU is not a bottleneck. The Core Ultra 7 265K has a multi-thread benchmark score of 58,838 and a single-thread score of 4,904, placing it in the 97th percentile of all CPUs. This processing headroom allows the Arc B580 to be the primary determinant of frame rate, especially at higher resolutions where the graphics load increases.

GPU Role

The Intel Arc B580 is the decisive component in this system's Doom performance. Its 12 GB of GDDR6 memory on a 192-bit bus provides 456.0 GB/s of bandwidth, which is ample for the game's textures at all tested settings. The GPU's core clocks are locked at a 2670 MHz base and boost, a static frequency that simplifies performance predictability. Its 2560 shading units and 80 ROPs are responsible for the rasterization workload, and the data shows a clear hierarchy based on resolution.

At 1920x1080, the GPU is able to flex its muscle, delivering 186.9 FPS on Low and 132.7 FPS on High. This indicates a strong fill-rate capability. The jump to 2560x1440 shows a predictable scaling, with the average frame rate on High settling at 88.6 FPS. The most demanding scenario, 3840x2160, exposes the GPU's limitations. Here, even with the reduced pixel count of the Low preset, the card can only muster 63.6 FPS, highlighting that the 80 ROPs and 13.67 TFLOPS of FP32 compute are taxed heavily by 4K rendering. The GPU's 66th percentile ranking and its competitive standing against the RTX 4060 confirm it is a solid mid-range performer, but not a 4K powerhouse.

Settings Recommendations

Based on the measured rows, the optimal experience depends heavily on your target resolution and refresh rate. For 1920x1080, the High preset at 132.7 FPS is the recommended starting point. It offers a significant visual upgrade over Medium (161.8 FPS) and Low (186.9 FPS) while still maintaining frame rates well above 120 FPS. Ultra, at 111.3 FPS, is only worth considering if you prioritize image quality over maximum smoothness and have a 120Hz display.

At 2560x1440, the High preset remains the best balance, delivering 88.6 FPS. This is comfortably within the range for a smooth experience on a 60Hz or 144Hz monitor. Dropping to Medium yields 101.4 FPS, a 14% increase, if you prefer higher frame rates over fidelity. The Low preset provides the maximum FPS at 119.4 but sacrifices too much visual quality for the modest gain over Medium. Ultra is not recommended here, as it drops to 69.7 FPS, which is a noticeable step down in smoothness.

For 3840x2160, the data is clear: stick to the Low preset (63.6 FPS) for a playable frame rate. Medium (57.2 FPS) is borderline, and High (49.7 FPS) and Ultra (40.8 FPS) are too slow for a responsive first-person shooter. If you have a 4K display, consider lowering the resolution to 2560x1440 for a much better experience.

How This Combo Ranks

This specific combination of the Intel Core Ultra 7 265K and Intel Arc B580 ranks 1300 out of 1681 tested combos in the database for Doom. This places it in the lower-middle tier of all possible pairings. The ranking reflects the system's performance ceiling, which is set by the GPU. While the CPU is a top-tier performer (97th percentile), the GPU's 66th percentile ranking pulls the overall combo down the list. The data suggests that while this is not a competitive combo for pushing the highest frame rates in Doom, it is a very capable one for mainstream gaming, particularly at 1080p and 1440p. The rank indicates that many combinations with higher-end GPUs will outperform it, but it also shows it is far from the bottom, offering a solid, balanced experience for its hardware class.

CPU Role

The Intel Core Ultra 7 265K provides substantial computational headroom for Doom. With 20 cores and 20 threads, it can handle the game's logic, physics, and AI without becoming a limiting factor. The high boost clock of 5.50 GHz, alongside a solid single-thread score of 4,904, ensures that the game's primary thread is well-served. Its multi-core might, demonstrated by a 58,838 score, is far beyond what Doom requires. The CPU's 97th percentile ranking versus all CPUs confirms its elite status.

This performance margin means that the measured frame rates in the game are almost entirely dictated by the Arc B580's rendering capabilities. The CPU is doing its job efficiently, feeding the GPU with data fast enough to avoid stutters or frame drops. The 30 MB of shared L3 cache and 102.4 GB/s of dual-channel DDR5 memory bandwidth provide a fast pathway for game data. The CPU's 3 nm process node and 125 W TDP also indicate high efficiency, allowing for sustained performance without excessive power draw or thermal throttling, which is beneficial for long gaming sessions.

Measured FPS Breakdown

The following data represents the average frame rates achieved by this combination in Doom, broken down by resolution and settings preset.

1920x1080:

• Low: 186.9 FPS
• Medium: 161.8 FPS
• High: 132.7 FPS
• Ultra: 111.3 FPS

At 1080p, the system is overwhelmingly GPU-bound, with the CPU providing more than enough support. The difference between Low and High is a 54.2 FPS gap, showing the impact of graphical settings on this resolution.

2560x1440:

• Low: 119.4 FPS
• Medium: 101.4 FPS
• High: 88.6 FPS
• Ultra: 69.7 FPS

The 1440p results show a tighter spread of 49.7 FPS between the lowest and highest presets. The High preset's 88.6 FPS is a strong result, indicating this resolution is the practical sweet spot for a high-refresh-rate monitor.

3840x2160:

• Low: 63.6 FPS
• Medium: 57.2 FPS
• High: 49.7 FPS
• Ultra: 40.8 FPS

At 4K, the GPU's performance limits are clear. All presets fall below the 66.6 FPS threshold for a perfectly smooth 60Hz experience, and only the Low preset manages to stay above 60 FPS on average. The data shows a steep performance cliff as settings increase, making 4K a challenging environment for this hardware.
