Doom

The Intel Core Ultra 7 265K paired with the NVIDIA GeForce RTX 5080 delivers a decisive performance profile in Doom, placing the combo in the 49th position out of 1,681 tested configurations. This pairing sits comfortably in the top percentile of systems, with the CPU ranking in the 97th percentile against all processors and the GPU in the 89th percentile against all graphics cards. The data indicates a system built for high-refresh-rate gaming, though the specific balance between the 20-core, 20-thread Arrow Lake CPU and the Blackwell-based GPU shifts depending on resolution and settings.

CPU Role

The Intel Core Ultra 7 265K brings 20 cores and 20 threads to the table, a configuration that emphasizes parallel throughput rather than hyper-threaded scaling. Its base clock of 3.90 GHz and boost clock of 5.50 GHz provide strong single-thread headroom, which is critical for a game like Doom that relies on rapid frame pacing and physics calculations. The processor’s 30 MB of shared L3 cache and 3 MB per-core L2 cache ensure that game data is readily accessible, reducing latency in frame generation.

In the context of this game’s results, the CPU’s role becomes evident when examining frame rates at lower resolutions. At 1920x1080 with Low settings, the combo hits 424.9 FPS average, a figure that far exceeds what any display can practically use but demonstrates that the processor is not the limiting factor. The 265K’s single-core performance, reflected in its Cinebench R23 single-core score of 7,060, allows the GPU to operate without starvation. Comparatively, the CPU’s nearest rival, the Intel Core Ultra 7 265KF, scores 79,240 average in synthetic benchmarks, a negligible 0.2% delta from the 265K’s 79,102 average. This near-identical performance confirms that the 265K’s integrated graphics and locked multiplier do not hamper its gaming capability.

The processor’s 3 nm process node and dual-channel DDR5 memory support with 102.4 GB/s bandwidth provide a modern foundation. In Doom, which was released in 2016 and does not demand extreme multi-threading, the 20-thread count offers headroom for background tasks while gaming. However, the data shows that the CPU’s influence wanes as resolution increases; at 4K, the GPU becomes the primary driver of frame rates, a pattern consistent across all tested settings.

Q: What is the performance difference between Low and Ultra settings at 1440p?

A: At 2560x1440, Low settings produce 277.5 FPS, while Ultra settings produce 166.2 FPS. This is a reduction of 111.3 FPS, or approximately 40%, when moving from the lowest to the highest preset, indicating that Ultra settings impose a substantial but manageable load on the GPU.

Q: Is the system more CPU-bound at lower resolutions?

A: Yes. The frame rate difference between 1080p and 4K at Low settings is 276.1 FPS (424.9 vs. 148.8), while at Ultra settings the difference is 166.7 FPS (257.7 vs. 91). The wider gap at Low settings suggests that the CPU is more capable of feeding frames at lower resolutions, whereas at higher resolutions the GPU’s rendering limits dominate.

Resolution Scaling

The data reveals a clear pattern of frame rate degradation as resolution increases from 1920x1080 to 3840x2160. At High settings, the average FPS drops from 315.2 at 1080p to 204.7 at 1440p, then to 112.6 at 4K. This represents a 35% reduction from 1080p to 1440p, and a further 45% reduction from 1440p to 4K. The scaling is not linear, with the 4K jump causing a more severe hit due to the exponential increase in pixel count.

At Low settings, the scaling is even more dramatic. The system produces 424.9 FPS at 1080p, dropping to 277.5 FPS at 1440p (a 35% decrease) and finally to 148.8 FPS at 4K (a 46% decrease from 1440p). These percentages suggest that the RTX 5080’s 16 GB of GDDR7 memory on a 256-bit bus with 960.0 GB/s bandwidth is sufficient to handle the data load, but the raw pixel throughput becomes the bottleneck at higher resolutions.

The limiting component shifts from CPU to GPU as resolution climbs. At 1080p, the 265K’s strong single-thread performance allows the GPU to reach 424.9 FPS, but at 4K, the GPU’s rendering capacity caps performance at 148.8 FPS even on Low settings. This is evidenced by the diminishing returns of CPU headroom; the processor’s 5.50 GHz boost clock cannot compensate for the GPU’s need to fill four times the pixels of 1080p. The Ultra preset at 4K drops to 91 FPS, showing that the GPU is heavily taxed by the combination of high resolution and maximum graphical fidelity.

How This Combo Ranks

The combo’s rank of 49 out of 1,681 tested systems places it in the upper echelon of Doom configurations. This ranking is a composite of the CPU’s 97th percentile standing and the GPU’s 89th percentile standing, with the combined result exceeding either individual percentile. The data suggests that the pairing is well-balanced, with neither component significantly dragging down the overall performance.

In practical terms, this rank means that the system outperforms approximately 97% of all tested combos for this game. The nearest CPU rivals, such as the Core i9-14900K, would likely produce similar results, but the RTX 5080’s specific architecture—including 10,752 shading units and 112 ROPs—contributes to its strong showing. The GPU’s pixel rate of 293.1 GPixel/s and texture rate of 879.3 GTexel/s are key metrics that drive Doom’s rendering efficiency.

The rank also indicates that this is not an absolute top-tier system; there are 48 combos that perform better. However, given the game’s 2016 release date, the margin between rank 49 and rank 1 is likely narrow, with differences of only a few FPS at 4K Ultra. The combo’s placement confirms the 265K’s and RTX 5080’s ability to handle legacy titles with extreme headroom.

Measured FPS Breakdown

At 1920x1080, the system delivers exceptional frame rates across all presets. Low settings yield 424.9 FPS, Medium settings 370.5 FPS, High settings 315.2 FPS, and Ultra settings 257.7 FPS. The progression is smooth, with each step up in quality costing roughly 40-60 FPS. These numbers indicate that 1080p is CPU-limited in this configuration, as even the lowest settings produce frame rates that exceed the GPU’s practical limits for most displays.

Moving to 2560x1440, the frame rates remain high but begin to show GPU influence. Low settings produce 277.5 FPS, Medium 239.3 FPS, High 204.7 FPS, and Ultra 166.2 FPS. The delta between Low and Ultra is 111.3 FPS, which is smaller than at 1080p (167.2 FPS difference). This compression suggests that the GPU is starting to become the primary constraint, though the CPU still provides ample headroom.

At 3840x2160, the GPU clearly dominates. Low settings yield 148.8 FPS, Medium 128.2 FPS, High 112.6 FPS, and Ultra 91 FPS. The delta between Low and Ultra is 57.8 FPS, showing a much tighter range. The 4K Ultra result of 91 FPS is still above 60 FPS, indicating playable performance even at maximum quality. The progression from Low to Ultra at 4K shows an average decrease of approximately 19 FPS per preset step, which is consistent with the GPU’s rendering load scaling with graphical complexity.

Settings Recommendations

Based on the measured rows, the best experience depends on the user’s display and preference for visual fidelity versus frame rate. For 1080p displays, Ultra settings at 257.7 FPS are recommended, as the frame rate far exceeds any practical refresh rate while delivering maximum visual quality. The 315.2 FPS at High is also valid, but the 57.5 FPS difference between High and Ultra is a minor trade-off for the graphical enhancements.

For 1440p, Ultra settings at 166.2 FPS provide an excellent balance, comfortably exceeding 144 Hz refresh rates while maintaining high visual standards. If the display supports 240 Hz, High settings at 204.7 FPS would be preferable, sacrificing some visual fidelity for a 38.5 FPS gain. Medium settings at 239.3 FPS are only recommended for competitive play where frame rate is paramount, as the drop from High to Medium is visually noticeable but yields a 34.6 FPS improvement.

At 4K, the choice is more nuanced. Ultra settings at 91 FPS are playable and offer the full experience, but High settings at 112.6 FPS provide a 21.6 FPS boost with minimal visual degradation. Medium settings at 128.2 FPS are a solid middle ground for those prioritizing smoothness, while Low settings at 148.8 FPS are best for high-refresh-rate 4K displays. The data does not show min or max FPS values, so stuttering cannot be assessed, but the average frame rates suggest that High is the recommended preset for 4K, offering the best compromise between the 91 FPS Ultra floor and the 148.8 FPS Low ceiling.
