Doom

The Intel Core Ultra 7 265K paired with the AMD Radeon RX 6600 XT delivers a solid, if not spectacular, experience in the 2016 classic Doom. The benchmark data shows a pairing where the CPU is rarely the bottleneck, leaving the GPU to dictate the final frame rates across resolutions and presets. The Core Ultra 7 265K, with its 20 cores and 20 threads, sits in the 97th percentile of all CPUs, while the RX 6600 XT lands in the 71st percentile for GPUs, a clear indication of which component is the limiting factor in this configuration.

Settings Recommendations

The measured data suggests that the "High" preset is the optimal choice for this hardware combination, striking the best balance between visual fidelity and playable frame rates. At 1920x1080, the High preset delivers a strong 143.5 FPS average, which is more than sufficient for the fast-paced action of Doom. While the "Ultra" preset at 1080p pushes the visual detail higher, it comes at a significant performance cost, dropping the average to 117.1 FPS, a 26.4 FPS reduction. The "Low" preset, while hitting 190.7 FPS, sacrifices needless visual quality for a frame rate advantage that most displays cannot even utilize.

The choice becomes clearer at higher resolutions. At 2560x1440, the High preset maintains a very playable 90.6 FPS average, making it the recommended choice for a high-refresh-rate 1440p monitor. The Ultra preset at this resolution dips to 77.3 FPS, which is still playable but introduces more variation and moves away from the ideal performance headroom. For 4K (3840x2160), the High preset drops to 47.8 FPS, which is a marginal experience. Users targeting 4K will find the Medium preset, at 59.1 FPS, to be the better compromise, offering a smoother experience than High while retaining more visual detail than Low. The data clearly indicates that the High preset is the sweet spot for this GPU, delivering the best experience per the measured rows for the majority of use cases.

Q: Is the Radeon RX 6600 XT a bottleneck for the Intel Core Ultra 7 265K?

A: Yes, the data suggests the GPU is the primary limiting factor. The CPU sits in the 97th percentile of all CPUs, while the GPU is in the 71st. This is corroborated by the FPS scaling, which changes significantly with resolution, a classic sign of a GPU-bound scenario.

Q: What is the performance difference between the Low and Ultra presets at 1080p?

A: At 1920x1080, the Low preset delivers an average of 190.7 FPS, while the Ultra preset delivers 117.1 FPS. This represents a performance drop of 73.6 FPS, or roughly a 38.6% reduction in average frame rate when moving from the lowest to the highest quality settings.

Q: How does the RX 6600 XT's benchmark score compare to other GPUs?

A: The RX 6600 XT has an average benchmark score of 27985. It performs 0.1% better than the NVIDIA GeForce GTX 980 Ti, which scores 27956, and is 0.9% behind the NVIDIA GeForce RTX 3070, which scores 28238.

Q: What is the frame rate at the High preset in 1440p?

A: At 2560x1440 with the High preset, the configuration achieves an average of 90.6 FPS. This is a solid performance level that is well-suited for a high-refresh-rate 1440p monitor.

GPU Role

The AMD Radeon RX 6600 XT is the defining component in this system's Doom performance. The GPU's architecture, RDNA 2.0, is built on a 7 nm process from TSMC and features 2048 shading units. Its memory configuration includes 8 GB of GDDR6 memory on a 128-bit bus, providing a bandwidth of 256.0 GB/s. Clock speeds are substantial, with a base clock of 1968 MHz, a game clock of 2359 MHz, and a boost clock up to 2589 MHz. These specifications allow the card to achieve a pixel rate of 165.7 GPixel/s and a texture rate of 331.4 GTexel/s.

In the context of Doom, these specifications translate directly to the measured frame rates. The game is a GPU-intensive title, and the RX 6600 XT's raw throughput is the primary driver of performance. The benchmark results follow a predictable pattern: as resolution and settings increase, the demand on the GPU's pixel and texture fill rates grows, and the average FPS consequently decreases. The GPU's 8 GB VRAM buffer is sufficient for the game's textures, even at the Ultra preset, as the performance drops are consistent with computational load rather than memory capacity issues. The card's DirectX 12 Ultimate support ensures full compatibility with the game's rendering paths. With a PassMark G3D score of 16461, it sits in the 71st percentile of all GPUs, a figure that aligns with its mid-range positioning and the FPS numbers observed in the data.

Measured FPS Breakdown

The measured FPS data provides a clear picture of the system's capabilities across a matrix of resolutions and presets. At 1920x1080, the configuration is never below a highly playable threshold. The Low preset yields a staggering 190.7 FPS average, while Medium and High follow with 168.9 and 143.5 FPS, respectively. Even the demanding Ultra preset maintains a strong 117.1 FPS average, ensuring a smooth experience on any 1080p display.

Moving to 2560x1440, the performance remains robust. The Low preset delivers 126.1 FPS, and the Medium preset achieves 105.8 FPS. The recommended High preset produces a very good 90.6 FPS average, which is ideal for 1440p gaming. The Ultra preset is still playable at 77.3 FPS, but it shows the GPU starting to work harder. At 3840x2160, the GPU's limitations become apparent. The Low preset manages 68.8 FPS, but the Medium preset drops to 59.1 FPS. The High preset falls to 47.8 FPS, and the Ultra preset bottoms out at 38.3 FPS, which is below the threshold for a comfortable experience for most players. The data shows a consistent and expected degradation in performance as both resolution and settings are increased.

Resolution Scaling

The frame rate scaling from 1920x1080 to 3840x2160 provides key insight into the system's bottleneck. At the Ultra preset, the average FPS drops from 117.1 at 1080p to 77.3 at 1440p, and finally to 38.3 at 4K. This represents a significant 67.3% reduction in performance from 1080p to 4K. A similar pattern is seen at the High preset, where the 143.5 FPS at 1080p falls to 90.6 FPS at 1440p and then to 47.8 FPS at 4K, a 66.7% drop.

This steep decline in frame rate is the classic signature of a GPU-bound workload. The Intel Core Ultra 7 265K, with its high single-threaded performance, is able to feed the GPU enough data at 1080p, but as the pixel count increases, the rendering demands outpace the GPU's capabilities. The CPU's performance headroom is evident in the fact that the FPS scales almost entirely with resolution. If the CPU were the limiting factor, the FPS would remain relatively flat across resolutions. Instead, the data shows a clear and pronounced drop, confirming that the Radeon RX 6600 XT is the component that determines the final frame rate, especially at higher resolutions like 1440p and 4K. The scaling indicates that for the best experience, users should prioritize resolution and settings that align with the GPU's mid-range performance profile.
