Doom

The Intel Core Ultra 7 265K paired with the AMD Radeon RX 6700 XT delivers a robust 1080p and 1440p experience in Doom, with 4K remaining viable only at reduced settings. The measured frame rates across the four presets indicate a system that is heavily GPU-limited at higher resolutions, while the 20-core processor provides ample headroom to push frame rates past the 200 FPS mark at 1080p. The data shows a clear hierarchy where the graphics card dictates the ceiling for visual fidelity, while the CPU ensures the floor remains high.

Settings Recommendations

For the best balance of visual quality and performance, the High preset at 2560x1440 is the recommended default. The data shows an average of 110.1 FPS at this setting, which is comfortably above the 60 FPS threshold for smooth gameplay and leaves headroom for demanding combat scenes. Moving to Ultra at the same resolution drops the average to 91.9 FPS, a significant 18.2 FPS penalty that is not justified by the incremental visual gains typically offered by the final preset tier.

At 1920x1080, the High preset achieves 172.6 FPS, which is excellent for high-refresh-rate monitors. The Ultra preset at 1080p yields 139.1 FPS, still very playable, but the 33.5 FPS difference between High and Ultra suggests the GPU is already working hard to maintain the higher fidelity settings. For competitive play where maximum frame rates are paramount, the Low preset at 1080p delivers 232.1 FPS, but this sacrifices the graphical detail that Doom’s environments are known for.

The 4K resolution presents a clear trade-off. The High preset at 3840x2160 produces 57.1 FPS, which is playable but not ideal for fast-paced action. The Low preset at 4K jumps to 81.4 FPS, but the visual compromise is substantial. The data suggests the Medium preset at 1440p is a strong middle ground, offering 131.8 FPS, which is 21.7 FPS higher than High and only slightly below the 1440p High result. The measured results indicate that the Ultra preset is the least efficient option, with the largest FPS drop relative to the previous tier at every resolution tested.

How This Combo Ranks

The combination of the Intel Core Ultra 7 265K and AMD Radeon RX 6700 XT ranks 928 out of 1681 tested combos for Doom, placing it in the 55th percentile of all configurations. This mid-pack ranking is consistent with a setup that pairs a high-end CPU with a mid-range GPU. The processor is a top-tier part, ranking in the 97th percentile against all CPUs, but the graphics card sits in the 77th percentile against all GPUs, creating a bottleneck that holds the combo back from higher overall rankings.

The CPU’s benchmark scores are notable. It scores 50,009 in Cinebench R23 multi-core and 7,060 in single-core, placing it within striking distance of its nearest rivals. The data shows the Core Ultra 7 265K is 0.2% behind the Core Ultra 7 265KF and the Core i9-14900KF, and 0.9% behind the Core i9-14900K in average benchmark score. This indicates the 265K is essentially at parity with the previous generation’s flagship, making it a strong foundation for gaming.

However, the GPU’s performance is more modest. The Radeon RX 6700 XT scores 19,786 in Passmark G3D and has an average benchmark score of 33,721. It is 0.7% behind the Radeon RX 6800 and 1.3% behind the NVIDIA RTX A5000 in the comparison data, while being 1% ahead of the AMD Radeon HD 7950 and RX 480. This places the GPU in a competitive mid-range tier, but it is not powerful enough to boost the overall combo ranking in a game as well-optimized as Doom, where high-end GPUs can achieve significantly higher frame rates.

GPU Role

The AMD Radeon RX 6700 XT is the primary determinant of frame rates in this configuration, particularly as resolution increases. The GPU features 12 GB of GDDR6 memory on a 192-bit bus, providing 384.0 GB/s of bandwidth. This memory configuration is sufficient for the textures and geometry in Doom, even at 4K, but the GPU’s compute capabilities are the limiting factor. The card has 2560 shading units and 160 texture mapping units, with a boost clock of 2581 MHz and a game clock of 2424 MHz, producing a peak FP32 throughput of 13.21 TFLOPS.

The measured FPS data confirms the GPU’s dominant role. At 1080p, the difference between Low and Ultra settings is 93 FPS (from 232.1 to 139.1), showing that the GPU is still processing a significant amount of work even at lower resolutions. At 4K, the spread narrows to 34 FPS (from 81.4 to 47.4), but this is because the GPU is saturated even at Low settings. The card’s pixel rate of 165.2 GPixel/s and texture rate of 413.0 GTexel/s are adequate for 1440p, but they struggle to maintain high frame rates at 4K with Enhanced settings.

The GPU’s DirectX 12 Ultimate support and Vulkan 1.4 API compatibility are well-suited to Doom’s engine, which is known for its Vulkan renderer. The 40 ray accelerators are present but not heavily utilized in this title, as Doom primarily relies on traditional rasterization. The data shows that the GPU’s performance is consistent with its 77th percentile ranking, meaning it outperforms a majority of GPUs but falls short of the high-end cards that can maintain 100+ FPS at 4K in this game.

FAQ

Q: What is the best resolution for this CPU-GPU combo in Doom?

A: The data indicates 2560x1440 is the optimal resolution. At High settings, it delivers 110.1 FPS, which is 53 FPS higher than the 4K High result of 57.1 FPS, while still offering a crisp image. The 1920x1080 results are higher but do not provide as much visual detail.

Q: How does the Ultra 7 265K compare to its closest rival, the 265KF?

A: The benchmark data shows the 265K has an average score of 79,102, which is 0.2% lower than the 265KF’s 79,240. This places the two processors in a statistical tie, with the 265K being the slightly slower variant in synthetic tests.

Q: Is the Radeon RX 6700 XT capable of 4K gaming in Doom?

A: Yes, but with limitations. The measured results show 57.1 FPS at High settings and 81.4 FPS at Low settings for 3840x2160. The Ultra preset drops to 47.4 FPS, which is below the ideal playable threshold, so High or Medium settings are recommended for 4K.

Q: What is the frame rate difference between Medium and High settings at 1440p?

A: The data shows the Medium preset achieves 131.8 FPS, while High achieves 110.1 FPS at 2560x1440. This represents a 21.7 FPS improvement when dropping from High to Medium, which is a significant gain for a relatively minor visual change.

Q: How does the combo rank among all tested configurations?

A: The combo ranks 928 out of 1681 tested combos for Doom. This places it in the middle of the pack, which is consistent with the pairing of a 97th percentile CPU with a 77th percentile GPU.

Q: Does the CPU bottleneck the GPU at 1080p?

A: No, the data suggests the opposite. At 1080p Low, the combo achieves 232.1 FPS, indicating the CPU is capable of feeding the GPU with enough data to reach very high frame rates. The GPU remains the limiting factor, as evidenced by the larger FPS drops when increasing settings.

Resolution Scaling

The performance scaling from 1080p to 4K reveals the GPU-centric nature of this configuration. At High settings, the average frame rate drops from 172.6 FPS at 1920x1080 to 110.1 FPS at 2560x1440, and finally to 57.1 FPS at 3840x2160. This represents a 115.5 FPS total reduction, or a 67% decrease, when moving from the lowest to the highest resolution. The scaling is relatively linear, with the 1440p result falling almost exactly halfway between the 1080p and 4K figures.

The data for Low settings shows a similar pattern: 232.1 FPS at 1080p, 149.4 FPS at 1440p, and 81.4 FPS at 4K. The percentage drop from 1080p to 4K is 64.9%, which is slightly less than the High preset’s drop. This indicates that at lower settings, the GPU is slightly less saturated, but it is still the primary performance limiter. The fact that the 4K Low result is significantly higher than the 4K Ultra result (81.4 vs 47.4 FPS) confirms that the GPU’s fill rate and shading power are the main constraints at high resolutions.

The Ultra preset exhibits the steepest scaling curve. It drops from 139.1 FPS at 1080p to 91.9 FPS at 1440p, and then to 47.4 FPS at 4K. The gap between 1440p and 4K is 44.5 FPS, which is the largest absolute drop across all settings for that resolution change. This suggests that the GPU’s memory bandwidth of 384.0 GB/s becomes a bottleneck when processing the increased pixel count and texture detail at 4K Ultra. The 12 GB VRAM is not exhausted, but the sheer volume of pixel data overwhelms the card’s 64 ROPs and 160 TMUs. The evidence points to the Radeon RX 6700 XT as the definitive limiting component, with the Intel Core Ultra 7 265K providing sufficient headroom to avoid any significant CPU-induced frame rate caps, even at lower resolutions.
