Doom

The measured data for Doom on the Intel Core Ultra 9 275HX and NVIDIA GeForce RTX 5080 Mobile shows strong performance across every preset. The combination ranks 1006th out of 3712 measured combos in Doom. Across the measured rows, average FPS ranges from 309 at 1080p Low to 65 at 4K Ultra, with the Medium presets also providing recorded minimum and maximum frame rates.

Settings Recommendations

The measured rows point to High as the most practical upper preset at 1080p and 1440p. At 1080p, Low averages 309 FPS, Medium averages 269 FPS, High averages 227 FPS, and Ultra averages 186 FPS. All four presets produce very high frame rates, so the choice is mostly about how much visual quality to trade for extra FPS. High at 1080p keeps 227 FPS while sitting above Medium’s visual level, and it still leaves a large margin over the lower presets. Ultra at 1080p remains a strong option at 186 FPS, but the measured data shows it is the slowest 1080p preset by a clear margin.

At 1440p, the situation is similar. Low averages 200 FPS, Medium averages 174 FPS, High averages 147 FPS, and Ultra averages 120 FPS. For a quality-focused setup, High at 1440p is a good recommendation because it stays above 147 FPS while delivering the same quality step used at 1080p. Medium at 1440p is also attractive for smoothness, with a recorded minimum of 148 FPS and a maximum of 200 FPS. Ultra at 1440p at 120 FPS is usable, but it is the first preset in the set to fall below the 147 FPS High result, so the quality gain has a measurable FPS cost.

At 4K, the recommended preset shifts downward. Low averages 108 FPS, Medium averages 94 FPS, High averages 80 FPS, and Ultra averages 65 FPS. The 4K Medium row is notable because it records a minimum of 80 FPS and a maximum of 109 FPS, which shows a stable frame rate range. High at 4K matches that 80 FPS figure as an average, but without a recorded minimum. Ultra at 4K drops to 65 FPS average. So for 4K, Medium gives the best measured balance: it is well above the High and Ultra presets, while still keeping a recorded floor of 80 FPS. Low at 4K remains available for maximum smoothness at 108 FPS average.

GPU Role

The NVIDIA GeForce RTX 5080 Mobile is based on the GB203 chip with Blackwell 2.0 architecture on a 5 nm process. It has 7,680 shading units, 240 texture mapping units, 96 ROPs, 60 RT cores, and 240 tensor cores. The GPU’s base clock is 975 MHz, with a boost clock of 1500 MHz, and the memory runs at 1750 MHz with 28 Gbps effective speed. The frame buffer is 16 GB of GDDR7 on a 256-bit bus, which produces 896.0 GB/s of memory bandwidth. These specifications support the high frame rates seen in the measured Doom rows, particularly at 1080p and 1440p.

The GPU’s aggregate benchmark average is 38,349, placing it at the 81st percentile of all GPUs. In the nearest rival data, it is 0.6% ahead of the NVIDIA GeForce RTX 4080 Mobile by average benchmark score, and 0.1% ahead of the NVIDIA GeForce MX570. It sits 0.9% behind the NVIDIA GeForce MX570 A and 0.9% behind the AMD Radeon Pro 580X in that same aggregate comparison. Those rival deltas are from synthetic benchmark averages, not from Doom itself, but they place the RTX 5080 Mobile in a competitive mobile GPU position.

In Doom, the GPU’s role becomes increasingly obvious as resolution rises. At 1080p High, the average is 227 FPS; at 1440p High, it is 147 FPS; at 4K High, it is 80 FPS. The same pattern appears on every preset. At 4K Ultra, the average falls to 65 FPS. The 16 GB frame buffer does not appear to cause a problem in the measured rows, because even the heaviest 4K preset still runs at a workable 65 FPS average. The GPU’s memory bandwidth and 256-bit bus are the kind of configuration that can feed a high-detail 4K render without the frame rate collapsing below the measured values.

Resolution Scaling

The measured FPS data shows a clear scaling pattern from 1080p to 1440p to 4K. At Low settings, 1080p averages 309 FPS, 1440p averages 200 FPS, and 4K averages 108 FPS. At Medium settings, 1080p averages 269 FPS, 1440p averages 174 FPS, and 4K averages 94 FPS. At High settings, 1080p averages 227 FPS, 1440p averages 147 FPS, and 4K averages 80 FPS. At Ultra settings, 1080p averages 186 FPS, 1440p averages 120 FPS, and 4K averages 65 FPS.

The largest single-step reductions in the measured data occur when moving from 1080p to 1440p. For example, Low drops from 309 FPS to 200 FPS, and Ultra drops from 186 FPS to 120 FPS. Moving from 1440p to 4K continues the downward trend, but the frame rates stay within a workable range on every preset. At 1080p Low, the machine almost reaches 300 FPS, which indicates that the CPU is capable of feeding an extremely high frame rate when the GPU has less pixel work. As resolution increases, the GPU’s rendering load grows, and the frame rate falls into the 65–108 FPS range at 4K depending on the preset.

This pattern says the limiting component changes with resolution. At 1080p, the CPU can keep up with the GPU well enough to allow 309 FPS on Low and 186 FPS on Ultra. At 4K, the data shows a GPU-bound situation: the same settings hierarchy remains, but the absolute frame rates compress into a lower band. The 4K Ultra result of 65 FPS and the 4K High result of 80 FPS both suggest that pixel throughput and shading work are the main constraints once the resolution reaches 4K.

CPU Role

The Intel Core Ultra 9 275HX is a 24-core, 24-thread mobile processor from the Core Ultra Series 2, built on Arrow Lake-HX architecture and a 3 nm process. It has a base clock of 2.70 GHz and a boost clock of 5.40 GHz, with a TDP of 55 W. The L3 cache is 36 MB shared, and the memory support is DDR5 over a dual-channel interface with 102.4 GB/s bandwidth. The CPU is unlocked, meaning the multiplier can be adjusted, though the measured Doom results do not indicate whether any overclocking was applied.

Synthetic benchmark data shows a strong all-around processor. The CPU scores 35,589 in Cinebench R23 multi-core and 2,204 in Cinebench R23 single-core. It scores 20,795 in Geekbench multi-core and 2,458 in Geekbench single-core. PassMark results include 55,759 for multi-thread and 4,713 for single-thread. Its aggregate average benchmark score is 67,469, which places it at the 94th percentile of all CPUs. The nearest rival data shows a 0.3% gap behind the Intel Xeon w5-3525, a 0.5% gap behind the AMD EPYC 4484PX, a 0.6% gap behind the AMD Ryzen Threadripper PRO 5955WX, and a 0.7% lead over the Intel Xeon 6515P.

In Doom, the CPU’s contribution is most visible at lower resolutions. At 1080p Low, the measured average is 309 FPS, which is the highest number in the entire measured set. At 1080p Medium, the average is 269 FPS, with a recorded maximum of 310 FPS. These numbers indicate that the CPU can drive frame rates well beyond typical display refresh rates when the GPU is not overloaded. At 4K, the CPU is less of a factor because the GPU becomes the limiting component, but the measured 108 FPS at 4K Low still requires a CPU that can feed the GPU efficiently.

The combination of 24 cores and 24 threads gives the Core Ultra 9 275HX substantial multi-threaded capacity, while the 5.40 GHz boost clock provides strong single-thread performance. For a game like Doom, the single-thread side matters for maintaining high frame rates in scenes that depend on game logic and draw calls. The measured 1080p results suggest the CPU has enough headroom to keep the RTX 5080 Mobile supplied with work at 1080p and 1440p. At 4K, the bottleneck moves to the GPU, and the CPU’s role becomes less obvious in the measured averages.

Only the Medium preset rows include recorded minimum and maximum values. At 1080p Medium, the minimum is 229 FPS and the maximum is 310 FPS. At 1440p Medium, the minimum is 148 FPS and the maximum is 200 FPS. At 4K Medium, the minimum is 80 FPS and the maximum is 109 FPS. These three rows provide some frame-time context for the Medium preset across each resolution, and they show that the recorded frame rate range narrows as resolution increases.

For the Low, High, and Ultra presets, the data only includes average FPS. Even so, the ordering is consistent at every resolution: Low is fastest, Medium is second, High is third, and Ultra is slowest. At 1080p, the average values are 309, 269, 227, and 186 for Low through Ultra. At 1440p, they are 200, 174, 147, and 120. At 4K, they are 108, 94, 80, and 65. The measured set is therefore complete enough to show both the settings hierarchy and the resolution scaling curve for this mobile combination.
