Doom

The pairing of the Intel Core Ultra 7 265K and the AMD Radeon RX 6800 XT delivers a robust experience in Doom, with the data showing that the graphics card is the primary bottleneck at higher resolutions. The CPU’s substantial core and thread count, however, ensures that even at lower settings, the system never falls behind the demands of the game engine. The measured frame rates across the resolution spectrum reveal a clear scaling pattern that prioritizes GPU headroom, making this combo a balanced choice for high-refresh-rate 1440p and solid 4K gameplay.

Resolution Scaling

The frame rate progression from 1080p to 4K demonstrates a typical GPU-bound curve, but with some notable nuances. At 1920x1080 with Low settings, the combo achieves an average of 290.8 FPS, which is a staggering 187% higher than the 4K Low result of 101 FPS. This massive gap at the lower preset indicates that the RX 6800 XT has ample headroom when the resolution is reduced, allowing the CPU to push frame rates to extreme levels. Moving to 2560x1440 with Low settings, the average drops to 188.8 FPS, a 35% decrease from the 1080p figure, showing a significant but expected penalty as pixel count increases.

At the High preset, the scaling is slightly less dramatic but still pronounced. The 1080p High average is 212.8 FPS, which falls to 138.3 FPS at 1440p and then to 72.4 FPS at 4K. This represents a 66% reduction from 1080p to 4K, indicating that the GPU’s compute and memory subsystems are being taxed heavily at the higher resolution. The Ultra preset shows a similar trend, with 175.6 FPS at 1080p dropping to 115.9 FPS at 1440p and finally to 63.9 FPS at 4K. The 4K Ultra result is notably close to the 60 FPS threshold, suggesting that this is the limit of the combo’s comfortable performance envelope.

What is most telling about the limiting component is the difference between Low and Ultra at each resolution. At 1080p, the gap is 115.2 FPS (290.8 vs 175.6), while at 4K the gap narrows to 37.1 FPS (101 vs 63.9). This compression of the delta as resolution increases confirms that the GPU becomes the sole bottleneck at 4K, whereas at 1080p, the CPU’s capability to feed the GPU becomes more relevant, though it still manages to stay ahead of the graphics card’s demands. The data strongly suggests that for maximum frame rates, 1080p is the playground, while 4K requires a compromise on settings to stay smooth.

CPU Role

The Intel Core Ultra 7 265K brings a formidable 20 cores and 20 threads to the table, which is a significant asset for a game like Doom that is known for its efficient multi-threaded engine. The processor’s base clock of 3.90 GHz and boost clock of 5.50 GHz provide the single-thread performance necessary to handle game logic and draw calls, while the 30 MB of shared L3 cache helps keep data close for quick access. In the benchmark data, the CPU’s role is evident in the fact that even at 1080p Low, where the GPU is least stressed, the frame rate does not exceed 290.8 FPS, suggesting that the CPU is capable of feeding the GPU with a high number of frames per second.

Looking at the synthetic benchmarks, the 265K posts a Cinebench R23 multi-core score of 50009 and a single-core score of 7060. This multi-core strength is crucial for Doom’s background simulation and AI, which can scale across many threads. The PassMark multi-thread score of 58838 further underscores the processor’s ability to handle concurrent workloads. In terms of its standing, the 265K has a percentile rank of 97 among all CPUs, indicating that it outperforms the vast majority of processors on the market. Its nearest rival, the Intel Core Ultra 7 265KF, scores an average of 79240, which is just 0.2% higher, showing that the 265K is essentially at parity with its direct counterpart.

The data indicates that the CPU is not the limiting factor in this combo, even at lower resolutions. The fact that the 1080p Low result of 290.8 FPS is the highest measured frame rate across all tests suggests that the 265K is capable of driving the RX 6800 XT to its maximum potential without introducing a CPU-bound ceiling. For a game released in 2016, the 265K’s modern architecture and high core count provide a massive surplus of processing power, ensuring that the GPU is always the limiting component in this configuration.

Settings Recommendations

The measured FPS rows provide a clear picture of which preset offers the best balance of visual quality and performance. At 2560x1440, the High preset yields an average of 138.3 FPS, which is well above the 144 Hz refresh rate that many gaming monitors target. This makes High the optimal choice for 1440p, as it provides a significant visual uplift over Medium (161.5 FPS) and Low (188.8 FPS) while still maintaining a frame rate that is smooth and responsive. The Ultra preset at 1440p drops to 115.9 FPS, which is still playable but offers diminishing returns for the performance hit.

For 4K gaming, the situation is more delicate. The Ultra preset at 3840x2160 averages 63.9 FPS, which is just above the 60 FPS baseline but may not be consistent enough for competitive play. The High preset at 4K averages 72.4 FPS, providing a 13% improvement over Ultra while likely offering a nearly identical visual experience, since the differences between High and Ultra in Doom are often subtle. The Medium preset at 4K delivers 91.7 FPS, which is a substantial jump and would be the recommended choice for players who prioritize frame rate stability over minor graphical enhancements. The Low preset at 4K reaches 101 FPS, but the visual compromises are likely too severe for a game that can look this good.

At 1080p, the choice is less critical, as even the Ultra preset averages 175.6 FPS. However, for players with 240 Hz monitors, the Low preset at 290.8 FPS or the Medium preset at 252 FPS would be the only options to fully saturate the display’s refresh rate. The data suggests that High at 1080p (212.8 FPS) is the sweet spot for most users, as it provides a high level of detail without sacrificing the frame rate headroom needed for competitive play. Overall, the best experience per the measured rows is High for 1440p and Medium for 4K, as these presets offer the best compromise between visual fidelity and performance.

How This Combo Ranks

The Intel Core Ultra 7 265K and AMD Radeon RX 6800 XT combination ranks 594 out of 1681 tested combos for Doom, placing it in the top 35% of all configurations. This is a respectable position, given that the RX 6800 XT is from the previous generation and the CPU is a strong but not top-tier enthusiast part. The rank indicates that while this combo is not among the absolute fastest for this game, it outperforms the majority of systems that have been benchmarked. The GPU’s percentile rank of 87 among all GPUs suggests that it is a high-performing part, but its age is reflected in the fact that it is not in the top decile.

The CPU’s rank of 97 among all CPUs, however, is exceptional, and this is likely what carries the combo to its 594th position. The data shows that the CPU is a more significant contributor to the combo’s overall standing than the GPU, as the 265K’s performance is closer to the top of the pack. The RX 6800 XT’s nearest rival, the NVIDIA GeForce RTX 4070 Ti SUPER, has an average benchmark score of 48704, which is 2.6% lower, indicating that the AMD card is still competitive with newer mid-range options. The combo’s rank of 594 suggests that users will experience high frame rates in Doom, but those seeking the absolute pinnacle of performance would need to invest in a more modern GPU.

The ranking also reflects the balance of the system. A combo with a weaker CPU but a stronger GPU might rank higher in games that are purely GPU-bound, but Doom’s engine benefits from the 265K’s multi-threaded capabilities. The fact that this combo achieves over 200 FPS at 1080p High and over 100 FPS at 4K Medium demonstrates that it is well-suited for a wide range of gaming scenarios. The rank of 594 is not a reflection of poor performance, but rather proof of the competition in the database, where many combos feature newer, more powerful hardware.

GPU Role

The AMD Radeon RX 6800 XT is the workhorse of this combo, and its role becomes more pronounced as resolution increases. The GPU features 16 GB of GDDR6 memory on a 256-bit bus, providing a bandwidth of 512.0 GB/s. This memory configuration is crucial for 4K gaming, as it allows the card to handle large textures and high-resolution buffers without hitting a capacity limit. The base clock of 1825 MHz and boost clock of 2250 MHz, combined with 4608 shading units, deliver a raw compute throughput of 20.74 TFLOPS, which is substantial for a card of this generation.

In Doom, the GPU’s dominance is clear from the resolution scaling data. At 4K, the difference between the Low and Ultra presets is only 37.1 FPS, indicating that the card is struggling to keep up with the pixel fill rate demands at that resolution. The Ultra preset at 4K delivers 63.9 FPS, which is exactly at the threshold of playability, while the High preset at 72.4 FPS shows that reducing a single setting tier can provide a 13% performance boost. This suggests that the card’s rasterization and texture throughput are the limiting factors at 4K, not the memory subsystem.

The GPU’s benchmark scores support this analysis. The PassMark G3D score of 24980 places it in the 87th percentile of all GPUs, which is strong but not elite. Its nearest rival, the Intel Arc A550M, has a score of 49737, which is 0.5% higher, indicating that the RX 6800 XT is closely matched with some mobile parts. The 3DMark Steel Nomad DX12 score of 3689 is a more modern benchmark, and it shows that the card can handle contemporary API workloads. The GPU’s launch MSRP is 649 USD, but the data shows that its performance in Doom is still relevant, especially at 1440p where it excels. The card’s 16 GB of VRAM future-proofs it for upcoming titles, but in Doom, the limiting factor is clearly the GPU’s compute and memory bandwidth, not its capacity.
