Doom

Doom’s 2016 engine scales aggressively with hardware, and the measured data for the Intel Core Ultra 7 265HX paired with the NVIDIA GeForce RTX 5090 shows a system that is overwhelmingly GPU-bound at every setting tier. The Ultra preset at 4K yields 70 FPS average, while dropping to High yields 85 FPS, Medium 101 FPS, and Low 116 FPS. The scaling pattern across resolutions indicates that the CPU is never the limiting factor, as even the most demanding 4K Ultra configuration produces playable frame rates. This combination ranks 584th out of 2,930 tested combos for this title, placing it in the top 20% of all systems evaluated, which is consistent with a top-tier mobile CPU and flagship desktop GPU pairing.

Settings Recommendations

The measured FPS rows provide a clear hierarchy for optimizing the experience in Doom. At 4K, the Ultra preset delivers 70 FPS average, which is technically playable but leaves little headroom for demanding scenes. The High preset at 4K produces 85 FPS average, a 21% improvement over Ultra, and the Medium preset reaches 101 FPS average with a minimum of 86 FPS, ensuring consistent frame pacing. The data shows that Medium at 4K is the sweet spot for a locked experience, as the 86 FPS minimum is still well above typical 60 Hz display refresh rates, while the 101 FPS average provides smooth motion.

For 1440p, the situation improves dramatically. Ultra at 2560x1440 yields 128 FPS average, which is sufficient for high-refresh-rate monitors in the 120-144 Hz range. High at 1440p delivers 157 FPS average, and Medium hits 186 FPS average with a minimum of 158 FPS. The measured minimum of 158 FPS at Medium 1440p is particularly noteworthy, as it ensures the frame rate never dips below the refresh rate of common 144 Hz panels, making this the recommended preset for competitive play at 1440p.

At 1080p, all presets exceed 198 FPS average, with Low reaching 330 FPS average and Medium achieving 287 FPS average with a maximum of 331 FPS. The Ultra preset at 1080p still produces 198 FPS average, which is more than enough for esports-level responsiveness. Given that the visual differences between Medium and Ultra are substantial in Doom’s particle-heavy encounters, the data suggests that Medium at 1080p or 1440p offers the best balance of visual fidelity and frame rate stability, as the minimum FPS at Medium is consistently 90-95% of the average across all resolutions.

CPU Role

The Intel Core Ultra 7 265HX is a 20-core, 20-thread processor based on the Arrow Lake architecture, manufactured on a 3 nm process by TSMC. Its base clock of 2.60 GHz and boost clock of 5.30 GHz provide substantial single-thread performance, as evidenced by a Cinebench R23 single-core score of 5,737 and a PassMark single-thread score of 4,500. The CPU’s multi-threaded capabilities are equally strong, with a Cinebench R23 multi-core score of 40,642 and a PassMark multi-thread score of 47,985.

In Doom, the CPU’s role is primarily to feed the GPU with draw calls and physics calculations. The data shows that the 265HX is more than adequate for this task, as frame rates scale nearly linearly with resolution when settings are held constant. For example, going from 1080p High (243 FPS) to 1440p High (157 FPS) represents a 35% reduction, while 4K High (85 FPS) is a further 46% reduction. This pattern indicates that the GPU is the bottleneck at all resolutions, as a CPU-bound scenario would show diminishing returns when lowering resolution.

The CPU’s 30 MB of shared L3 cache and dual-channel DDR5 memory support with 102.4 GB/s of bandwidth are sufficient for Doom’s level streaming and texture management. The PassMark physics score of 2,978 and data compression score of 511,817 suggest that the CPU can handle the game’s rigid body physics and asset decompression without stuttering. The nearest rival comparisons show the 265HX performing within 0.7% of the Intel Core Ultra 7 255HX and within 0.5% of the AMD Ryzen AI Embedded P185 in average benchmark scores, indicating that CPU performance differences are negligible for this game’s frame pacing.

How This Combo Ranks

The combination of the Intel Core Ultra 7 265HX and NVIDIA GeForce RTX 5090 ranks 584th out of 2,930 tested combos for Doom, placing it in the top 19.9% of all systems. This ranking is notable given that the GPU has a percentile of 92 vs all GPUs and the CPU has a percentile of 93 vs all CPUs. The rank is somewhat lower than the individual component percentiles might suggest, which indicates that other combos with similar or slightly lower component scores achieve better frame rates in this specific title.

The data shows that this combo’s performance is heavily skewed by the GPU’s strengths, as the RTX 5090’s PassMark G3D score of 39,650 and 3DMark Steel Nomad DX12 score of 18,355 are exceptional. However, the ranking of 584 suggests that there are 583 combos that outperform this pairing, likely due to desktop CPUs with higher sustained clocks or systems with more optimized memory configurations. The nearest GPU rivals in synthetic benchmarks are the NVIDIA Tesla P100 PCIe 16 GB (0.3% higher avg score) and AMD Radeon RX 6850M XT (1.1% higher), but these do not directly translate to Doom performance, where the RTX 5090’s architecture excels.

Resolution Scaling

The measured FPS data reveals a consistent scaling pattern across resolutions. At High settings, the frame rates are 243 FPS at 1080p, 157 FPS at 1440p, and 85 FPS at 4K. This represents a 35% drop from 1080p to 1440p and a further 46% drop from 1440p to 4K. At Medium settings, the pattern is similar: 287 FPS at 1080p, 186 FPS at 1440p, and 101 FPS at 4K, with drops of 35% and 46% respectively. At Ultra settings, the frame rates are 198 FPS at 1080p, 128 FPS at 1440p, and 70 FPS at 4K, showing drops of 35% and 45%.

This consistent 35% and 45-46% scaling pattern indicates that the GPU is the primary limiting component at all resolutions. If the CPU were the bottleneck, the frame rate differences between resolutions would be smaller, as the CPU would cap performance regardless of pixel count. The proportional scaling suggests that the RTX 5090’s rendering throughput scales linearly with pixel count, which is typical for a GPU-bound scenario in a well-optimized engine like Doom’s id Tech 6. The fact that the drops are nearly identical across all settings presets further confirms that neither the CPU nor memory bandwidth is constraining performance.

The frame rate spread from Low to Ultra is 86 FPS, with the Medium preset’s minimum of 158 FPS being nearly identical to High’s average of 157 FPS. This indicates that Medium at 1440p offers similar performance to High but with better frame pacing.

At 3840x2160, the Low preset yields 116 FPS average, Medium yields 101 FPS average with a minimum of 86 FPS and a maximum of 116 FPS, High yields 85 FPS average, and Ultra yields 70 FPS average. The Ultra preset at 4K is the only configuration in the entire dataset that drops below 70 FPS average, and the Medium preset’s minimum of 86 FPS is still above the 60 FPS threshold for smooth gameplay. The data shows that the 4K Medium preset with its 101 FPS average and 86 FPS minimum provides the best combination of resolution and frame rate stability for this combo.

GPU Role

The NVIDIA GeForce RTX 5090 is a flagship GPU based on the Blackwell 2.0 architecture, fabricated on a 5 nm process by TSMC. It features 21,760 shading units, 680 texture mapping units, and 176 ROPs, with a base clock of 2017 MHz and a boost clock of 2407 MHz. The GPU’s 32 GB of GDDR7 memory on a 512-bit bus provides 1.79 TB/s of bandwidth, which is critical for Doom’s high-resolution texture streaming at 4K.

The GPU’s PassMark G3D score of 39,650 and 3DMark Steel Nomad DX12 score of 18,355 place it in the 92nd percentile vs all GPUs. Its nearest rivals in synthetic benchmarks include the NVIDIA Tesla P100 PCIe 16 GB with a 0.3% higher average score and the AMD Radeon Pro Vega 64X with a 1.4% lower average score. In Doom, the GPU’s role is dominant, as evidenced by the resolution scaling analysis showing consistent 35-46% frame rate drops when increasing resolution.

The RTX 5090’s 170 ray tracing cores and 680 tensor cores are not directly utilized by Doom’s 2016 engine, which relies on traditional rasterization. However, the GPU’s raw compute throughput of 104.8 TFLOPS FP32 and texture rate of 1,636.8 GTexel/s ensure that even the most demanding scenes with multiple enemies and particle effects are rendered without bottleneck. The 32 GB VRAM capacity is far more than Doom’s requirements, but it ensures that the game’s texture cache never spills to system memory, maintaining consistent frame times across all presets. The GPU’s 575 W TDP and 950 W suggested PSU indicate that this is a power-hungry component, but the measured FPS data shows it delivers exceptional performance in Doom at every resolution and settings combination.
