Doom

The benchmark data for Doom with the Intel Core Ultra 7 265HX and NVIDIA GeForce RTX 5080 Mobile shows a system with substantial headroom across all tested settings. The measured results indicate that the combination of the 20-core Arrow Lake-HX processor and the Blackwell-based mobile GPU delivers high frame rates even at 4K, with the most demanding preset still maintaining a playable average. The data suggests a balanced platform where the GPU’s 16 GB of GDDR7 memory and 896.0 GB/s bandwidth are sufficient to feed the display pipeline without obvious bottlenecks at lower resolutions.

Settings Recommendations

The measured FPS rows provide clear guidance for optimal settings based on resolution. At 3840x2160, the Ultra preset yields an average of 65 FPS, which is technically playable but leaves little room for dips in busy scenes. The High preset at the same resolution improves the average to 80 FPS, a 23% uplift over Ultra, while the Medium preset reaches 94 FPS with a recorded minimum of 80 FPS and maximum of 109 FPS. Given that the data shows the Medium preset at 4K provides a smoother experience with a higher floor, it is the recommended choice for 4K displays where visual fidelity is still strong but frame pacing is prioritized.

For 2560x1440, the situation changes. The High preset delivers 147 FPS, while Ultra drops to 120 FPS. The Medium preset at 174 FPS offers a significant margin over High, but the jump from Medium to High is only 27 FPS, whereas the drop from High to Ultra is also 27 FPS. This suggests that High at 1440p is the sweet spot for users with high-refresh monitors, as it maintains a triple-digit average without sacrificing the visual quality that Ultra provides. The Low preset at 200 FPS is only recommended for competitive play where maximum frame rate is the sole priority.

At 1920x1080, all presets exceed 186 FPS, making the choice less about playability and more about visual quality. The Ultra preset at 186 FPS is fully playable and offers the best image quality, but the High preset at 227 FPS provides a 22% improvement in average FPS with only a modest reduction in settings. For users with 240 Hz displays, the Medium preset at 269 FPS is the best option, as it stays well above the refresh threshold while still providing better visuals than Low. The Low preset at 309 FPS is the maximum measured performance, but the data shows that the GPU has enough headroom to justify higher settings without falling below the 144 FPS threshold that most gaming monitors require.

GPU Role

The NVIDIA GeForce RTX 5080 Mobile is the primary driver of the measured results, and its specifications explain the performance envelope. The GPU features 16 GB of GDDR7 memory on a 256-bit bus, yielding a bandwidth of 896.0 GB/s. This memory configuration is critical for Doom’s texture streaming and high-resolution rendering, as the 4K Medium preset’s minimum FPS of 80 suggests that memory bandwidth is sufficient to avoid stutter. The GPU’s boost clock of 1500 MHz and base clock of 975 MHz are modest for a mobile part, but the 7680 shading units and 240 tensor cores compensate through raw parallel throughput.

The FP32 performance of 23.04 TFLOPS is the key metric for Doom’s Vulkan-based rendering, and the data shows that this compute capability scales well with resolution. At 1080p Low, the GPU produces 309 FPS, but this drops to 108 FPS at 4K Low, a 65% reduction. This scaling pattern indicates that the GPU is the limiting factor at higher resolutions, as the CPU’s 5.30 GHz boost clock is more than capable of feeding frames at 1080p. The GPU’s 81st percentile ranking among all GPUs and its average benchmark score of 38349 place it in the upper tier, but the nearest rivals list includes the RTX 4080 Mobile with a deltaPct of 0.6%, meaning performance is closely matched to that older flagship.

The RTX 5080 Mobile’s 60 RT cores and 240 tensor cores do not directly impact Doom’s traditional rasterization path, but they contribute to the GPU’s overall efficiency. The measured pixel rate of 144.0 GPixel/s and texture rate of 360.0 GTexel/s are sufficient to maintain the high frame rates observed. The GPU’s 80 W TDP is low for its performance class, which suggests that thermal throttling is unlikely to be a factor in the measured results, allowing the boost clock to sustain over extended sessions.

How This Combo Ranks

The combo of the Intel Core Ultra 7 265HX and RTX 5080 Mobile ranks 1006 out of 3712 tested combinations in Doom. This places the system in the top 27% of all tested hardware pairings, which is a strong showing for a mobile platform. The rank is influenced by both the CPU’s 93rd percentile ranking among all CPUs and the GPU’s 81st percentile ranking, but the combination’s position suggests that neither component is holding the other back significantly.

Comparing the CPU to its nearest rivals in the database, the Ultra 7 265HX scores an average benchmark score of 63173, which is 0.1% ahead of the Intel Core i7-13790F (63080) and 0.7% ahead of the Intel Core Ultra 7 255HX (62738). The GPU’s average score of 38349 is 0.6% ahead of the RTX 4080 Mobile (38135), indicating that the 5080 Mobile is a marginal upgrade over the previous generation. These deltas are small, meaning the combo’s rank is more dependent on the game’s specific optimization than on raw hardware superiority.

The data shows that the combo performs best at lower resolutions, where the CPU’s 20 threads and 30 MB of L3 cache can keep the GPU fed. At 1080p Ultra, the system achieves 186 FPS, which is 2.9 times the 4K Ultra result of 65 FPS. This scaling factor is typical for a GPU-bound title, and the rank of 1006 reflects that the system is not in the top tier for 4K gaming but is highly capable for 1440p and 1080p.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across three resolutions and four settings. At 3840x2160, the Low preset averages 108 FPS, Medium averages 94 FPS with a minimum of 80 and maximum of 109, High averages 80 FPS, and Ultra averages 65 FPS. The progression from Low to Ultra shows a 40% reduction in average FPS, which is a significant but expected drop for a demanding preset. The Medium preset’s minimum FPS of 80 is notable because it matches the High preset’s average, indicating that Medium provides a more consistent experience than High.

At 2560x1440, the Low preset reaches 200 FPS, Medium averages 174 FPS with a minimum of 148 and maximum of 200, High averages 147 FPS, and Ultra averages 120 FPS. The gap between Medium and High is 27 FPS, while the gap between High and Ultra is also 27 FPS, showing a linear scaling pattern. The Low preset’s 200 FPS is exactly equal to the Medium preset’s maximum, suggesting that the GPU’s frame output is capped by the CPU at this resolution for lower settings.

At 1920x1080, the Low preset averages 309 FPS, Medium averages 269 FPS with a minimum of 229 and maximum of 310, High averages 227 FPS, and Ultra averages 186 FPS. The minimum FPS at Medium (229) is higher than the High preset’s average (227), which indicates that the Medium preset offers a better frame pacing experience than High. The maximum FPS at Medium (310) is nearly identical to the Low preset’s average (309), showing that the CPU is beginning to limit performance at this resolution. The Ultra preset’s 186 FPS is still well above the 144 Hz refresh rate, making it a viable option for high-refresh displays.

CPU Role

The Intel Core Ultra 7 265HX is a 20-core, 20-thread processor based on the Arrow Lake-HX architecture, with a base clock of 2.60 GHz and a boost clock of 5.30 GHz. Its 30 MB of shared L3 cache and 3 MB per-core L2 cache are substantial for a mobile part, and the 102.4 GB/s memory bandwidth on a dual-channel DDR5 bus ensures that data can be fed to the GPU without starvation. The CPU’s benchmark results are strong, with a Cinebench R23 multi-core score of 40642 and a single-core score of 5737, placing it in the 93rd percentile of all CPUs.

In Doom, the CPU’s role is most evident at lower resolutions. At 1080p Low, the system reaches 309 FPS, which is the highest measured average, but the Medium preset’s maximum FPS of 310 suggests that the CPU is hitting its frame generation ceiling. The 20 cores and 20 threads are more than enough for Doom’s multi-threaded rendering, but the single-thread performance, as indicated by the PassMark single-thread score of 4500, is what drives the high frame rates at 1080p. At 1440p and 4K, the GPU becomes the bottleneck, and the CPU’s performance is less critical.

The CPU’s nearest rival comparisons show that it is within 0.7% of the Intel Core Ultra 7 255HX and 0.5% of the AMD Ryzen AI Embedded P185, meaning that small clock differences have minimal impact on gaming performance. The processor’s 55 W TDP is modest, allowing it to maintain boost clocks without excessive thermal load, which is important for sustained gaming sessions. The data indicates that the CPU is not a limiting factor in Doom, as the frame rates scale predictably with GPU load.

Resolution Scaling

The measured FPS data reveals a clear scaling pattern from 1080p to 4K. At the Low preset, the system averages 309 FPS at 1080p, 200 FPS at 1440p, and 108 FPS at 4K. This represents a 35% drop from 1080p to 1440p and a 46% drop from 1440p to 4K. The scaling is more aggressive at the Medium preset, where the averages are 269 FPS at 1080p, 174 FPS at 1440p, and 94 FPS at 4K, showing a 35% and 46% drop respectively. This consistent pattern indicates that the GPU is the primary limiting factor, as the CPU’s performance is sufficient to maintain high frame rates at lower resolutions.

The High preset shows a slightly different scaling curve, with 227 FPS at 1080p, 147 FPS at 1440p, and 80 FPS at 4K. The drop from 1080p to 1440p is 35%, but the drop from 1440p to 4K is 46%, which is steeper than the Low preset. This suggests that the High preset’s additional rendering features, such as higher texture quality and shadow detail, place more strain on the GPU’s memory bandwidth at 4K. The Ultra preset follows a similar pattern, with 186 FPS at 1080p, 120 FPS at 1440p, and 65 FPS at 4K, representing a 35% and 46% drop respectively.

The resolution scaling data points to the GPU as the bottleneck at 4K, as the 896.0 GB/s bandwidth and 23.04 TFLOPS of FP32 performance are the limiting factors. The CPU’s 5.30 GHz boost clock and 20 threads are more than capable of handling the increased draw calls at 4K, but the GPU’s fill rate and memory bandwidth determine the final frame rate. The fact that the scaling is consistent across all presets indicates that the system is well-balanced, with no single component causing a disproportionate drop in performance.
