Doom

The Intel Core Ultra 5 125H paired with the NVIDIA GeForce RTX 5080 delivers a broad spread of frame rates in Doom, ranging from a 309 FPS average at 1080p Low to a 65 FPS average at 4K Ultra. This combination of a mobile 14-core processor and a desktop-class Blackwell GPU produces results that are consistently playable, though the gap between the fastest and slowest tested configurations is substantial. The measured data provides a clear picture of how each setting tier and resolution affects performance, and where the bottlenecks lie.

Settings Recommendations

For 1920x1080, the data shows that every settings preset produces an average frame rate well above 144 FPS. The Low preset reaches 309 FPS, Medium averages 269 FPS, High averages 227 FPS, and Ultra still manages 186 FPS. Since even the most demanding preset at this resolution keeps the average above 180 FPS, the choice comes down to visual fidelity versus headroom. The Ultra preset at 1080p delivers 186 FPS, which is still excellent for fast-paced FPS play, and the minimum frame rate on Medium is 229 FPS, indicating strong consistency. For competitive play where maximum smoothness is the priority, the Low preset at 309 FPS offers the largest margin, but the data suggests that High at 227 FPS provides a balanced trade-off with a 41 FPS deficit from Low while presumably offering better visuals. The Medium preset’s minimum of 229 FPS and maximum of 310 FPS show that this setting is also well within the territory of high-refresh displays.

At 2560x1440, the pattern shifts. Low averages 200 FPS, Medium averages 174 FPS with a minimum of 148 FPS, High averages 147 FPS, and Ultra drops to 120 FPS. Here, the Medium preset stands out because its minimum frame rate of 148 FPS is close to the High preset’s average, meaning that Medium offers a more consistent experience than the average alone suggests. For users with 144 Hz monitors, the High preset at 147 FPS is borderline, while Medium at 174 FPS with a 148 FPS minimum provides a safer margin. The Ultra preset at 120 FPS is still playable but falls below the 144 FPS threshold that many FPS players target. Based on the measured rows, Medium at 1440p is the recommended choice: it delivers 174 FPS average, which is 27 FPS higher than High, and its minimum of 148 FPS ensures that even demanding scenes stay above the 144 FPS mark.

At 3840x2160, the situation becomes more constrained. Low averages 108 FPS, Medium averages 94 FPS with a minimum of 80 FPS, High averages 80 FPS, and Ultra averages 65 FPS. For 4K gaming, the Low preset is the only one that clears the 100 FPS threshold, but it likely sacrifices significant visual quality. The Medium preset at 94 FPS with a minimum of 80 FPS is the most balanced option for a 60 Hz or 90 Hz display, as it maintains an average close to 100 FPS while keeping the minimum above 80 FPS. The High preset matches the Medium preset’s minimum at 80 FPS but has a lower average of 80 FPS, making it less attractive. The Ultra preset at 65 FPS is playable on a 60 Hz screen but leaves little headroom for frame time spikes. Given the data, Medium at 4K is the recommended setting because it offers the best combination of a 94 FPS average and an 80 FPS minimum, which is sufficient for smooth gameplay on most 4K displays.

CPU Role

The Intel Core Ultra 5 125H is a mobile processor with 14 cores and 18 threads, a base clock of 3.60 GHz, and a boost clock of 4.50 GHz. Its L3 cache is 18 MB shared, and it belongs to the Meteor Lake architecture built on a 7 nm process. In synthetic benchmarks, this CPU scores 12,804.5 in Cinebench R23 multi-core and 1,647.5 in single-core, with a PassMark multi-thread score of 21,100 and a single-thread score of 3,399. The percentile vs all CPUs is 79, meaning it outperforms 79% of all tested processors. Its nearest rivals include the AMD Ryzen 7 5800 with an average score of 27,535 (0.1% higher), the Intel Core i5-12600K with an average score of 27,578 (0.3% higher), and the AMD Ryzen 7 5700X with the same score of 27,578 (0.3% higher). The AMD Ryzen 3 PRO 5355G scores 27,382, which is 0.5% lower than the Ultra 5 125H’s average benchmark score of 27,507.

In Doom, the CPU’s role is evident when examining the FPS scaling across resolutions. At 1080p Low, the average FPS is 309, which is the highest measured in the entire dataset. This suggests that at lower resolutions and settings, the CPU is capable of feeding the GPU enough data to reach very high frame rates. However, as the resolution increases to 1440p and 4K, the average FPS drops significantly even at the same settings preset, indicating that the GPU becomes the primary limiter. For example, at Low settings, the average FPS goes from 309 at 1080p to 200 at 1440p to 108 at 4K. This 201 FPS drop from 1080p to 4K at Low settings is far larger than what would be expected from a pure CPU bottleneck. The CPU’s 14 cores and 18 threads, with a boost clock of 4.50 GHz, are more than sufficient for Doom’s engine, as evidenced by the 309 FPS ceiling at 1080p Low. The single-core performance, as measured by the Cinebench R23 score of 1,647.5, is adequate for this game’s main thread, but the data does not show any scenario where the CPU limits the frame rate below what the GPU can deliver at higher resolutions.

The CPU’s nearest rivals all have similar average benchmark scores, with deltas of -0.1% to 0.5%, which means the Ultra 5 125H is statistically comparable to a desktop Ryzen 7 5800 or Core i5-12600K in general compute. In Doom, this level of CPU performance is unlikely to be the deciding factor at 4K, where the GPU’s workload dominates. The fact that the Ultra preset at 1080p still achieves 186 FPS suggests that the CPU can handle the game’s physics and AI even at maximum settings, leaving the GPU as the sole constraint.

GPU Role

The NVIDIA GeForce RTX 5080 is the dominant component in this pairing. It features 16 GB of GDDR7 memory on a 256-bit bus with a bandwidth of 960.0 GB/s, and its memory clock is 1875 MHz (30 Gbps effective). The GPU’s base clock is 2295 MHz with a boost clock of 2617 MHz, and it has 10,752 shading units, 336 TMUs, and 112 ROPs. The chip is GB203 built on a 5 nm process from TSMC, with 45,600 million transistors on a 378 mm² die. The RTX 5080’s FP32 performance is 56.28 TFLOPS, and its texture rate is 879.3 GTexel/s. In synthetic benchmarks, it scores 36,565 in PassMark G3D and 235,901 in Geekbench OpenCL, with a percentile vs all GPUs of 87. Its nearest rivals include the AMD Radeon 8060S with an average score of 55,757 (0.6% higher), the AMD Radeon RX 6750 GRE 12 GB with an average score of 55,698 (0.7% higher), and the AMD Radeon Pro W5700X with an average score of 54,828 (2.3% higher). The AMD Radeon RX 9070 GRE scores 57,367, which is 2.2% lower than the RTX 5080’s average benchmark score of 56,083.

In Doom, the GPU’s performance is clearly the limiting factor as resolution increases. At 1080p, the RTX 5080 is not fully utilized, as shown by the 309 FPS average at Low settings, which is likely near the game engine’s or CPU’s ceiling. At 1440p, the GPU begins to show its strength: the Low preset averages 200 FPS, and the Ultra preset averages 120 FPS, indicating that the GPU can handle the increased pixel count without collapsing. At 4K, the GPU’s workload becomes severe. The Low preset averages 108 FPS, Medium 94 FPS, High 80 FPS, and Ultra 65 FPS. The 16 GB of VRAM is ample for Doom at any of these settings, since the game’s texture requirements are unlikely to exceed that capacity, even at 4K Ultra. The memory bandwidth of 960.0 GB/s is more than sufficient, as the frame rate drops from Ultra to Low at 4K (65 to 108 FPS) are consistent with a shader-bound rather than memory-bound scenario.

The RTX 5080’s boost clock of 2617 MHz and its 56.28 TFLOPS of FP32 compute power are the key drivers of these results. The data shows that the GPU’s performance scales roughly with resolution: from 1080p to 1440p at High settings, the average FPS drops from 227 to 147, a 35% reduction. From 1440p to 4K at High, the average drops from 147 to 80, a 46% reduction. These diminishing returns are typical of a GPU that has enough power for 1440p but struggles to maintain high frame rates at 4K under heavy settings. The GPU’s PassMark G3D score of 36,565 places it in the 87th percentile, and its nearest rivals all have similar scores, so this level of performance is consistent with its position in the market.

Resolution Scaling

The measured FPS data reveals a consistent pattern of performance degradation as resolution increases from 1080p to 4K. At Low settings, the average FPS drops from 309 at 1080p to 200 at 1440p to 108 at 4K. This represents a 35% reduction from 1080p to 1440p and a further 46% reduction from 1440p to 4K. At Medium settings, the averages are 269 (1080p), 174 (1440p), and 94 (4K), with corresponding reductions of 35% and 46%. The High preset follows the same pattern: 227 (1080p), 147 (1440p), and 80 (4K), with reductions of 35% and 46% as well. The Ultra preset shows 186 (1080p), 120 (1440p), and 65 (4K), with reductions of 35% and 46% respectively.

The consistency of these percentage drops across all settings presets is striking. For every preset, the 1080p-to-1440p reduction is exactly 35%, and the 1440p-to-4K reduction is exactly 46%. This uniformity indicates that the scaling is driven by pixel count and fill rate, which are functions of the GPU, rather than by CPU or memory bandwidth. If the CPU were the bottleneck, the percentage drops would likely be smaller at higher resolutions, because the CPU’s work would be spread across more pixels. Instead, the GPU’s rendering workload scales directly with resolution, and the RTX 5080’s performance decreases proportionally.

The 4K-to-1080p ratio shows that the GPU is heavily tasked at 4K. For example, at High settings, the 4K average of 80 FPS is only 35% of the 1080p average of 227 FPS. This indicates that the RTX 5080 is not capable of maintaining high frame rates at 4K for Doom, even though it excels at 1080p and 1440p. The limiting component at 4K is clearly the GPU, as the CPU’s performance remains constant regardless of resolution, and the data shows a linear scaling with pixel count. For users targeting 4K, the Low preset at 108 FPS is the only way to get close to 100 FPS, while Medium at 94 FPS is the highest quality option that stays above 90 FPS.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest results. The Low preset averages 309 FPS with no recorded minimum or maximum. The Medium preset averages 269 FPS, with a minimum of 229 FPS and a maximum of 310 FPS. The High preset averages 227 FPS, again without min/max data. The Ultra preset averages 186 FPS. The spread between Low and Ultra at 1080p is 123 FPS, showing that the settings preset has a significant impact even at this resolution. The Medium preset’s minimum of 229 FPS is higher than the High preset’s average of 227 FPS, which suggests that Medium may offer better frame pacing than High, despite the lower average.

At 2560x1440, the averages are lower but still robust. Low averages 200 FPS, Medium averages 174 FPS with a minimum of 148 FPS and a maximum of 200 FPS, High averages 147 FPS, and Ultra averages 120 FPS. The gap between Low and Ultra is 80 FPS, which is smaller than at 1080p, indicating that the GPU is becoming more of a factor. The Medium preset’s minimum of 148 FPS is close to the High preset’s average of 147 FPS, reinforcing the idea that Medium is a stable choice at 1440p. The Ultra preset at 120 FPS is the only preset below 144 FPS, which may be noticeable on high-refresh displays.

At 3840x2160, the performance drops significantly. Low averages 108 FPS, Medium averages 94 FPS with a minimum of 80 FPS and a maximum of 109 FPS, High averages 80 FPS, and Ultra averages 65 FPS. The spread between Low and Ultra is 43 FPS, which is the smallest gap across all resolutions. This suggests that at 4K, even the Low preset is limited by the GPU, so the relative difference between settings shrinks. The Medium preset’s minimum of 80 FPS matches the High preset’s average, indicating that Medium provides a more consistent experience than High at 4K. The Ultra preset at 65 FPS is the only setting that falls below 80 FPS average, and its minimum is not recorded, but the average suggests it may dip below 60 FPS in demanding scenes.

How This Combo Ranks

In the global database of tested CPU and GPU combinations for Doom, this pairing of the Intel Core Ultra 5 125H and NVIDIA GeForce RTX 5080 ranks 745th out of 2,930 combos. This places it in the top 25.4% of all tested configurations. Given that the RTX 5080 is a high-end GPU with an 87th percentile ranking among all GPUs, and the CPU is a mobile processor with a 79th percentile ranking among all CPUs, the combo’s overall rank of 745 is somewhat lower than the GPU’s individual standing. This suggests that the mobile CPU may be holding back the system in some scenarios, particularly at lower resolutions where CPU overhead is more prominent.

The combo rank of 745 means that 2,185 other combinations deliver higher average frame rates in Doom. These likely include desktop CPUs paired with the same or similar GPUs, as desktop processors with higher sustained clocks and more robust power delivery can reduce CPU bottlenecks. However, the measured FPS data shows that at 4K, the combo still achieves 80 FPS on High and 65 FPS on Ultra, which are respectable numbers for a demanding resolution. The rank of 745 out of 2,930 is primarily a reflection of the CPU’s mobile nature, as the GPU’s performance is near the top of its class. For a laptop-based system, this rank is strong, but it does not place the combo among the absolute elite for Doom, where desktop CPUs with high single-thread performance and high-bandwidth memory would likely push higher frame rates at 1080p and 1440p. The data does not include direct comparisons to other combos, so the exact delta in FPS to the 744th or 746th combo is unknown, but the percentile position is clear.
