Doom

The Intel Core Ultra 5 125H paired with the NVIDIA GeForce RTX 5080 Mobile delivers a compelling Doom experience, with the data showing a combination that scales effectively across resolutions. This analysis breaks down the measured performance, contextualizes the results against other tested configurations, and provides practical settings guidance based on the benchmark rows.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 5080 Mobile is the dominant force in this pairing, and its specifications align well with Doom’s demands. The GPU features 16 GB of GDDR7 memory on a 256-bit bus, yielding a bandwidth of 896.0 GB/s. For a fast-paced FPS like Doom, which benefits from rapid texture streaming and high frame rates, this memory configuration is more than sufficient; the data shows no indication of VRAM capacity or bandwidth bottlenecks at any tested setting. The GPU’s base clock is 975 MHz with a boost clock of 1500 MHz, and it houses 7680 shading units, 240 TMUs, and 96 ROPs. The pixel rate of 144.0 GPixel/s and texture rate of 360.0 GTexel/s provide the raw throughput needed to sustain high frame rates, particularly at lower resolutions where the CPU has more headroom.

The RTX 5080 Mobile’s architecture is Blackwell 2.0, built on a 5 nm process at TSMC, with 60 RT cores and 240 tensor cores. While Doom is not a ray-tracing showcase, the presence of these cores ensures future-proofing for titles that leverage them. The GPU’s FP32 performance of 23.04 TFLOPS is a strong indicator of its rasterization capability, which is what matters most for this game. The 80 W TDP classification is noteworthy for a mobile part, but the benchmark results suggest that power delivery is sufficient to maintain performance across all measured configurations.

The Intel Core Ultra 5 125H plays a supporting role, but its specifications are not trivial. With 14 cores and 18 threads, a base clock of 3.60 GHz, and a boost clock of 4.50 GHz, this Meteor Lake processor provides ample compute for game logic and draw calls. The 18 MB of shared L3 cache is adequate for feeding the GPU, and the dual-channel memory support with 89.6 GB/s bandwidth is typical for a mobile platform. In Doom, which is not heavily CPU-bound at high settings, the CPU’s role is to avoid becoming a limiting factor; the measured FPS numbers indicate that it succeeds in this regard, as the GPU remains the primary driver of performance differences across settings and resolutions.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data provides a clear picture of how this combo performs across three resolutions and four quality presets. At 1080p, the results are exceptionally high, with the Low preset averaging 309 FPS, Medium averaging 269 FPS (with a min of 229 and max of 310), High averaging 227 FPS, and Ultra averaging 186 FPS. These numbers indicate that the RTX 5080 Mobile is far from being challenged at this resolution; even the most demanding preset, Ultra, maintains an average well above the refresh rates of most gaming monitors. The gap between Low and Ultra is 123 FPS, showing that the settings scale predictably without any sudden drop-offs.

Moving to 1440p, the performance remains strong but begins to show the GPU’s workload increasing. The Low preset averages 200 FPS, Medium averages 174 FPS (min 148, max 200), High averages 147 FPS, and Ultra averages 120 FPS. The progression from Low to Ultra is smooth, with each step costing roughly 25-27 FPS on average. The minimum FPS recorded at Medium (148) is still well above 60, indicating that even in demanding scenes, the experience remains fluid. At 1440p Ultra, the 120 FPS average is a solid result for a mobile GPU, suggesting that high-refresh-rate 1440p gaming is viable for this title.

At 4K, the performance drops are more pronounced, but the results are still respectable. The Low preset averages 108 FPS, Medium averages 94 FPS (min 80, max 109), High averages 80 FPS, and Ultra averages 65 FPS. The Ultra preset’s 65 FPS average is close to the 60 FPS threshold, and while it is playable, it lacks the headroom seen at lower resolutions. The Medium preset’s minimum of 80 FPS is a notable data point, as it shows that even with occasional dips, the experience remains above the console-level target. The 4K results highlight that this combo is capable of 4K gaming, but users will need to make settings trade-offs to achieve consistently high frame rates.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The FPS scaling from 1080p to 4K reveals a clear pattern: the GPU is the primary limiting component, with the CPU providing sufficient headroom to avoid becoming a bottleneck. At the High preset, the average FPS drops from 227 at 1080p to 147 at 1440p, a reduction of 80 FPS or 35.2%. From 1440p to 4K, the drop is from 147 to 80 FPS, a reduction of 67 FPS or 45.6%. The percentage drop increases as resolution rises, which is typical for a GPU-bound scenario. The total drop from 1080p to 4K at High is 147 FPS, meaning the 4K average is only 35.2% of the 1080p average.

At the Low preset, the scaling is similar but with higher absolute numbers. The average drops from 309 FPS at 1080p to 200 FPS at 1440p (a 35.3% reduction) and then to 108 FPS at 4K (a 46.0% reduction from 1440p). The total drop from 1080p to 4K is 201 FPS, with the 4K average being 34.9% of the 1080p average. This consistency across presets indicates that the rendering load scales linearly with pixel count, and the GPU’s fill rate and shading capacity are the determining factors.

The Medium preset’s data includes minimum and maximum FPS values, which add nuance to the scaling analysis. At 1080p, the average is 269 FPS with a min of 229 and max of 310. At 1440p, the average drops to 174 FPS (min 148, max 200), and at 4K, it falls to 94 FPS (min 80, max 109). The minimum FPS at 4K (80) is still above 60, showing that even the worst-case scenarios are playable. The spread between min and max FPS narrows as resolution increases, which is expected because the GPU becomes more consistently saturated at higher pixel counts, reducing the impact of scene complexity variations.

The scaling behavior strongly suggests that the Intel Core Ultra 5 125H is not a limiting factor in Doom. If the CPU were the bottleneck, we would expect to see smaller FPS differences between 1080p and 1440p, as the GPU would have spare capacity. Instead, the consistent ~35% drop from 1080p to 1440p and ~46% drop from 1440p to 4K across all presets indicates that the RTX 5080 Mobile is doing the heavy lifting. The CPU’s 14 cores and 18 threads, along with its 4.50 GHz boost clock, are more than adequate for this game’s engine, which is not known for being particularly CPU-intensive at high settings.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and refresh rate. At 1080p, all presets deliver excellent performance, with even the Ultra preset averaging 186 FPS. For users with 144 Hz or 165 Hz monitors, the High preset at 227 FPS provides a comfortable margin above the refresh rate, while the Ultra preset’s 186 FPS is also sufficient. The Medium preset at 269 FPS is the best choice for maximizing frame rates on very high refresh rate displays, as it offers a significant boost over High without a noticeable visual penalty in a fast-paced game like Doom.

At 1440p, the High preset’s 147 FPS average is ideal for 144 Hz displays, providing a smooth experience with good visual fidelity. The Ultra preset’s 120 FPS average is also viable for 120 Hz monitors, and the 27 FPS difference between High and Ultra may be worth it for users who prioritize image quality. The Medium preset at 174 FPS is recommended for those seeking the highest frame rates on 165 Hz or 180 Hz panels, as it stays above the refresh rate threshold while still looking respectable. The Low preset at 200 FPS is unnecessary unless chasing maximum competitive performance, as the visual downgrade is substantial.

At 4K, the settings trade-offs become more critical. The Ultra preset’s 65 FPS average is playable but leaves little headroom for demanding scenes, making it a marginal choice. The High preset at 80 FPS is a better option, as it provides a smoother experience while still maintaining high visual quality. The Medium preset at 94 FPS (min 80) is the recommended choice for 4K gaming, as it offers the best balance of performance and fidelity, keeping the minimum FPS above 60. The Low preset at 108 FPS is suitable for users who prioritize frame rate over everything else, but the visual compromises are significant at this resolution. For most players, the Medium preset at 4K delivers the most consistent and enjoyable experience, with the High preset serving as a viable alternative for those who prefer higher visual settings and can tolerate slightly lower frame rates.
