Settings Recommendations

The measured FPS data suggests that the optimal balance between visual fidelity and performance lies at the High preset. At 2560x1440, High settings deliver 157 FPS average, which is 29 FPS higher than Ultra (128 FPS) while remaining visually rich. The jump from High to Ultra costs 29 FPS at 1440p and 15 FPS at 4K, which is a significant penalty for incremental graphical improvements.

For players targeting the highest refresh rates, the Low preset at 1920x1080 offers 330 FPS, but this sacrifices too much visual quality for most users. The Medium preset at 1080p provides a more balanced 287 FPS, which still exceeds the refresh rate of most high-end monitors. At 4K, Medium settings produce 101 FPS, which is the minimum recommended threshold for smooth gameplay on standard 60Hz displays, while High bumps this to 85 FPS with better image quality.

The data shows that Ultra settings are only advisable for players with G-Sync or FreeSync displays who prioritize image quality over raw frame rates. At 1440p Ultra, the 128 FPS average is still playable, but the 70 FPS at 4K Ultra approaches the lower boundary of what is considered smooth for fast-paced FPS titles. Benchmark results indicate that High settings offer the best compromise, delivering 157 FPS at 1440p and 85 FPS at 4K, which represents a 23% and 21% improvement over Ultra respectively.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals a clear pattern of GPU limitation. At High settings, frame rates drop from 243 FPS at 1080p to 157 FPS at 1440p (a 35% reduction), then to 85 FPS at 4K (a 46% reduction from 1440p). This steep decline indicates that the RTX 5090 Mobile’s rendering pipeline becomes the primary bottleneck as pixel count increases.

At Low settings, the scaling is even more dramatic: 330 FPS at 1080p, 214 FPS at 1440p, and 116 FPS at 4K. The 1080p to 1440p drop of 116 FPS (35%) suggests that even at Low settings, the GPU cannot maintain the frame rates that the CPU could theoretically support. The CPU’s 24 cores and 24 threads, with a boost clock of 5.40 GHz, are more than capable of feeding the GPU at 1080p, but the GPU’s 31.80 TFLOPS FP32 performance becomes the limiting factor as resolution increases.

Interesting data point: the FPS drop from 1080p to 1440p is consistently around 35% across all settings (35% for High, 35% for Low, 35% for Medium, 35% for Ultra). This consistency strongly suggests that the scaling is purely resolution-driven, with no CPU bottleneck appearing at any settings level. The 1440p to 4K drops are more variable (46% for High, 46% for Low, 46% for Medium, 45% for Ultra), which may indicate slight variations in GPU memory bandwidth utilization at higher resolutions.

Measured FPS Breakdown

1920x1080: The combo delivers its highest performance at this resolution. Low settings produce 330 FPS average, Medium 287 FPS (with min 244 and max 331), High 243 FPS, and Ultra 198 FPS. The spread between Low and Ultra is 132 FPS, showing that settings have a substantial impact at 1080p. The Medium preset’s max FPS of 331 nearly matches the Low preset’s average, indicating that the GPU can occasionally hit extreme frame rates even at higher settings.

2560x1440: Performance remains very strong at this resolution. Low settings yield 214 FPS, Medium 186 FPS (min 158, max 214), High 157 FPS, and Ultra 128 FPS. The gap between Low and Ultra narrows to 86 FPS, suggesting that the GPU is beginning to feel the resolution pressure. The Medium preset’s min FPS of 158 is still well above the refresh rate of most 1440p monitors, making this a safe choice for competitive play.

3840x2160: At 4K, the combo still delivers playable frame rates across all settings. Low settings average 116 FPS, Medium 101 FPS (min 86, max 116), High 85 FPS, and Ultra 70 FPS. The drop from Low to Ultra is 46 FPS, which is the smallest absolute spread of any resolution, indicating that the GPU is the dominant constraint at 4K. The Medium preset’s min FPS of 86 ensures that even the worst-case frame times remain above 60 FPS, which is crucial for maintaining smooth gameplay.

The data shows that Medium settings at 4K provide the most consistent experience, with a min FPS of 86 that is 16 FPS higher than the High preset’s average. This suggests that Medium is the safest choice for 4K gaming on this combo, as it maintains a comfortable margin above the 60 FPS threshold even during intense scenes.

GPU Role

The RTX 5090 Mobile’s specifications directly explain its performance in Doom. The GPU features 10496 shading units, 328 TMUs, and 112 ROPs, operating at a boost clock of 1515 MHz. This configuration yields 31.80 TFLOPS of FP32 performance, which is substantial for a mobile part. The 24 GB of GDDR7 memory on a 256-bit bus provides 896.0 GB/s of bandwidth, ensuring that texture streaming at 4K Ultra never becomes a bottleneck.

Benchmark results place the GPU in the 84th percentile versus all GPUs, with an average benchmark score of 45152. Its nearest rival, the AMD Radeon Pro 5500 XT, scores 45384 (0.5% higher), while the Intel Arc A730M scores 45592 (1% higher). The data shows that the RTX 5090 Mobile is competitive with desktop-class GPUs from previous generations, which explains its ability to maintain high frame rates in Doom.

The GPU’s memory subsystem is particularly relevant for this game. Doom is known for its large texture sets, and the 24 GB VRAM capacity ensures that even Ultra settings at 4K do not exceed memory limits. The 896.0 GB/s bandwidth is more than sufficient for the game’s asset streaming, as evidenced by the consistent frame times at 4K Medium (min 86 FPS). The GPU’s 82 RT cores and 328 tensor cores are not directly utilized by Doom’s standard rendering path, but they contribute to the GPU’s overall compute capability.

The measured FPS data indicates that the GPU is the primary performance limiter at all resolutions above 1080p. At 1440p Ultra, the combo achieves 128 FPS, which is 35% lower than at 1080p Ultra. This scaling aligns with the pixel count increase (1.78x), suggesting that the GPU’s fill rate and shading capacity are the constraining factors. The GPU’s pixel rate of 169.7 GPixel/s and texture rate of 496.9 GTexel/s are impressive but cannot fully compensate for the 4K resolution’s 8.3 million pixel workload.

CPU Role

The Intel Core Ultra 9 275HX provides ample processing power for Doom, which is a well-optimized game that can utilize multiple cores. The CPU features 24 cores and 24 threads (no hyperthreading), with a base clock of 2.70 GHz and a boost clock of 5.40 GHz. This configuration, based on the Arrow Lake architecture, delivers a Cinebench R23 multi-core score of 35589 and a single-core score of 2204.

The CPU’s performance relative to rivals is remarkably close. Its average benchmark score of 67469 is only 0.3% lower than the Intel Xeon w5-3525 (score 67673) and 0.5% lower than the AMD EPYC 4484PX (score 67822). This tight clustering suggests that for Doom, the CPU is not a differentiating factor; any of these processors would likely deliver similar frame rates.

Benchmark data shows the CPU’s multi-threaded capabilities: PassMark multithread score of 55759, Cinebench R20 multi-core of 19899, and Geekbench multi-core of 20795. These scores indicate strong parallel processing, but Doom’s engine does not scale perfectly with core count. The game’s main thread benefits from the CPU’s high single-core performance (PassMark single-thread score of 4713), while secondary threads utilize the additional cores for physics and AI.

The CPU’s 36 MB of L3 cache (shared) and 3 MB L2 per core provide ample cache for game data. The memory bandwidth of 102.4 GB/s (Dual-channel DDR5) is sufficient for feeding the GPU at high frame rates, as evidenced by the 330 FPS at 1080p Low. At this setting, the CPU can generate frames faster than the GPU can render them, but the CPU is not the bottleneck—the GPU’s rendering capabilities cap the frame rate.

Interestingly, the CPU’s 94th percentile ranking and 24-core configuration suggest it could handle even higher frame rates if the GPU were faster. The fact that frame rates drop consistently by 35% from 1080p to 1440p across all settings indicates that the GPU is the limiting component, not the CPU. The CPU’s boost clock of 5.40 GHz ensures that even the most demanding game logic runs without stutter, as shown by the consistent min FPS values at 4K Medium (86 FPS).

How This Combo Ranks

The combo ranks 788th out of 3712 tested combinations for Doom, placing it in the top 21.2% of all systems. This ranking reflects the GPU’s 84th percentile performance and the CPU’s 94th percentile performance, but the combination’s overall position is dragged down by the fact that Doom is a relatively older title (released in 2016) that may not fully utilize the latest hardware features.

The CPU’s near-tie with the Intel Xeon w5-3525 (0.3% difference) and AMD EPYC 4484PX (0.5% difference) suggests that the CPU choice has minimal impact on the combo’s rank. The GPU’s performance relative to rivals is more variable: it is 1.8% slower than the RTX 5880 Ada Generation but 0.8% faster than the RTX 4070 Ti. This GPU positioning likely drives the combo’s rank more than the CPU.

The combo’s rank of 788 out of 3712 means that 2924 other combinations perform better in Doom. Given that the RTX 5090 Mobile is a high-end mobile GPU, this ranking may seem lower than expected. However, the data shows that Doom’s performance is heavily dependent on raw GPU throughput, and the RTX 5090 Mobile’s mobile form factor (95 W TDP) may limit its sustained performance compared to desktop GPUs.

The measured FPS data supports this ranking: at 4K Ultra, the combo achieves 70 FPS, which is solid but not exceptional. The GPU’s average benchmark score of 45152 places it in the 84th percentile, but its nearest rivals include the RTX 4070 Ti, which is a desktop card. This suggests that the mobile RTX 5090’s performance is comparable to mid-to-high-end desktop GPUs from the previous generation, which explains the 788th rank among thousands of combinations that include desktop parts.
