Doom

The Intel Core Ultra 7 265K paired with the AMD Radeon RX 7900 XT delivers a formidable performance profile in Doom, demonstrating a clear hierarchy across resolutions and presets. The data confirms this pairing is heavily skewed toward high-refresh-rate 1440p and 1080p gaming, while still maintaining very playable frame rates at 4K.

Settings Recommendations

For the best balance of visual fidelity and performance, the High preset is the recommended starting point across all tested resolutions. At 1920x1080, the High preset delivers an average of 249.6 FPS, which is a substantial 45.9 FPS advantage over the Ultra preset's 203.7 FPS. This gap suggests that the jump from High to Ultra extracts a significant performance cost without a proportional visual benefit in fast-paced action.

At 2560x1440, the High preset produces 163.8 FPS, comfortably exceeding the refresh rate of most high-end monitors. Moving to Medium yields 188.5 FPS, but the difference of 24.7 FPS over High is less critical at this resolution, as both remain well above 144Hz. The Ultra preset at 1440p drops to 134.8 FPS, which is still smooth but begins to sacrifice the headroom needed for 144Hz+ displays.

For 4K gaming, the High preset maintains an average of 88.1 FPS, which is excellent for a demanding resolution. The Medium preset offers 102.3 FPS, a 14.2 FPS improvement that may be preferable for those targeting 100 FPS. However, the Ultra preset falls to 69.1 FPS, which is playable but noticeably less fluid. The Low preset, while reaching 116.1 FPS at 4K, sacrifices too much visual quality for a marginal gain over Medium.

The data indicates that High is the optimal preset for this combination. It provides a strong balance at 1080p and 1440p, and remains the most sensible choice for 4K where Ultra's visual enhancements do not justify the 19 FPS loss compared to High.

FAQ

A: Using the High preset, the average FPS at 1920x1080 is 249.6, while at 3840x2160 it is 88.1. This is an increase of approximately 161.5 FPS when moving to the lower resolution.

Q: What is the performance difference between Low and Medium settings at 4K?

A: At 3840x2160, the Low preset averages 116.1 FPS, and Medium averages 102.3 FPS. The Low preset is 13.8 FPS faster, a modest gain for a substantial reduction in visual quality.

GPU Role

The AMD Radeon RX 7900 XT is the dominant component in this pairing for Doom, with its 20 GB of GDDR6 memory on a 320-bit bus providing 800.0 GB/s of bandwidth. This memory configuration is more than sufficient for the game's textures and assets, even at 4K Ultra settings. The GPU's boost clock of 2394 MHz and game clock of 2025 MHz drive its compute performance, which includes 5376 shading units and 192 ROPs for pixel output.

The GPU's influence is most apparent in the scaling of frame rates with graphical settings. At 4K, moving from Medium to Ultra reduces performance from 102.3 FPS to 69.1 FPS, a 33.2 FPS drop that directly correlates with increased GPU workload. This pattern confirms that the RX 7900 XT is the primary bottleneck when settings are raised, as the CPU has ample headroom. The GPU's percentile ranking of 82 among all GPUs places it in the upper tier, and its average benchmark score of 38358 is virtually identical to the NVIDIA GeForce RTX 5080 Mobile, with a delta of 0%.

The GPU's raw compute power is showcased by its 51.48 TFLOPS FP32 performance, which allows it to handle the high polygon counts and effects in Doom without issue. The card's end-of-life production status does not diminish its current capability, as the data shows it consistently delivers high frame rates. The effective memory speed of 20 Gbps combined with the large frame buffer ensures that texture streaming and high-resolution rendering do not introduce stutter.

How This Combo Ranks

Within the benchmark database, this specific configuration of the Intel Core Ultra 7 265K and AMD Radeon RX 7900 XT holds the 369th position out of 1681 tested combos for Doom. This places it in the top 22% of all combinations, a strong result that underscores its high-end status. The ranking reflects the measured FPS data, which shows this system excels at high refresh rates, particularly at 1080p and 1440p.

The CPU component of this combo, the Core Ultra 7 265K, sits in the 97th percentile against all CPUs, with an average benchmark score of 79102. Its nearest rival, the Intel Core Ultra 7 265KF, scores 79240, a negligible -0.2% difference. This indicates that the CPU is not a limiting factor in the overall combo ranking. Similarly, the GPU's percentile ranking of 82 and its average score of 38358 are competitive, as evidenced by its 0% delta with the NVIDIA GeForce RTX 5080 Mobile.

The combo's rank of 369 out of 1681 suggests that while many systems are faster, this pairing is far from the bottom of the pack. The data implies that the strong CPU and GPU synergy produces consistent results, with the system's performance being defined more by the GPU's limits than any CPU bottleneck. For context, the CPU's nearest rivals, such as the Intel Core i9-14900K with a -0.9% delta, show that the 265K is performing at the expected level for its class.

Resolution Scaling

The frame rate progression across resolutions reveals a classic GPU-bound scenario. At the High preset, the average FPS drops from 249.6 at 1080p, to 163.8 at 1440p, and finally to 88.1 at 4K. This represents a 65.8 FPS decrease from 1080p to 1440p, and a further 75.7 FPS decrease from 1440p to 4K. The percentage drop from 1080p to 4K is approximately 64.7%, indicating that the rendering resolution has a profound impact on performance.

This scaling pattern is typical of a system where the GPU is the primary limiter. The CPU, with its 20 cores and 30 MB of shared L3 cache, is more than capable of feeding the GPU at all tested resolutions. The data shows that even at 1080p Low, where the CPU would be most likely to bottleneck, the system reaches 337 FPS, which is well within the CPU's capability.

The difference between 1440p and 4K is particularly telling. At High settings, the 75.7 FPS drop when moving to 4K is larger than the 65.8 FPS drop from 1080p to 1440p. This is because 4K contains over twice as many pixels as 1440p, placing a significantly higher load on the GPU's shading units and memory bandwidth. The RX 7900 XT's 800.0 GB/s bandwidth is taxed heavily at this resolution, but it still manages to deliver over 88 FPS on High, demonstrating its efficiency. The data confirms that for maximum frame rates, 1080p is the preferred resolution, but for a balance of image quality and speed, 1440p is the sweet spot, with 4K remaining a viable option on High settings.
