Doom

The Intel Core Ultra 9 185H paired with the AMD Radeon RX 7900M delivers a remarkably fluid experience in Doom, with the measured data showing that this combination is capable of pushing well beyond standard display refresh rates at most settings. The benchmark results indicate a system where the GPU is the primary driver of performance, yet the CPU provides more than enough headroom to avoid becoming a bottleneck. This analysis breaks down the measured FPS across resolutions and presets, offering practical guidance on how to configure the game for the best balance of visual fidelity and performance.

Settings Recommendations

The measured data suggests that the High preset offers the most balanced experience across all tested resolutions, serving as the optimal default for most players. At 1920x1080, the High preset delivers an average of 190 FPS, which is 35 FPS lower than Low but provides substantially better visual quality. The jump from Medium to High is only a 35 FPS reduction at 1080p, while the jump from High to Ultra costs 35 FPS as well, making High the sweet spot for competitive play on high-refresh monitors.

Moving to 2560x1440, the High preset maintains an average of 123 FPS, which remains comfortably above the 100 FPS threshold for smooth gameplay. This is particularly notable because the Ultra preset at this resolution drops to exactly 100 FPS, meaning that High offers 23% more performance than Ultra while the visual difference between the two presets is often difficult to discern in fast-paced action. For players with 144Hz monitors, the High preset at 1440p is the clear recommendation, as the 123 FPS average leaves enough headroom to avoid frequent dips below the refresh rate.

At 3840x2160, the High preset still manages an average of 67 FPS, which is playable but not ideal for competitive play. The Medium preset at 4K offers 79 FPS, which is 18% faster than High, and the measured minimum of 67 FPS for Medium indicates that the frame pacing remains consistent. For 4K users, the Medium preset provides the best compromise, as the Ultra preset at 54 FPS is likely to feel sluggish during intense firefights. The Low preset at 4K reaches 90 FPS, but the visual sacrifice is significant, making it a less attractive option compared to simply lowering the resolution.

The data reveals a clear pattern: the High preset is the best choice for 1080p and 1440p, while Medium is the most practical option for 4K. Players who prioritize maximum frame rates above all else can use the Low preset, which yields 258 FPS at 1080p and 167 FPS at 1440p, but the quality reduction is substantial. The Ultra preset is only recommended for players with G-Sync or FreeSync displays who want the highest visual fidelity and can tolerate frame rates in the 54-155 FPS range depending on resolution.

GPU Role

The AMD Radeon RX 7900M is the dominant component in this pairing, and the measured FPS data clearly reflects its capabilities. This GPU features 16 GB of GDDR6 memory on a 256-bit bus, providing 576.0 GB/s of bandwidth, which is more than sufficient for Doom's texture-heavy environments at all tested settings. The 16 GB memory capacity ensures that even the Ultra preset at 4K will not encounter VRAM limitations, as the game's memory footprint at this resolution remains well within the available pool.

The GPU's clock behavior is interesting when compared to the measured results. With a base clock of 1825 MHz and a boost clock of 2090 MHz, the RX 7900M demonstrates that raw clock speed is less important than the underlying architecture. The RDNA 3.0 architecture with 4608 shading units and 192 ROPs delivers the raw throughput needed for Doom's Vulkan-based rendering engine. The measured 3DMark Steel Nomad DX12 score of 4201 and the Geekbench Vulkan score of 158760 both place this GPU in the 94th percentile of all GPUs, confirming its high-end positioning.

The GPU's performance relative to its nearest rivals shows that the RX 7900M is competitive with professional workstation cards. The average benchmark score of 97487 is nearly identical to the AMD Radeon Pro VII, which scores 97131 with a delta of 0.4%, and it outperforms both the AMD Radeon Instinct MI60 (92466, 5.4% delta) and the NVIDIA RTX A4500 (91671, 6.3% delta). The NVIDIA Quadro RTX 6000 scores higher at 101872, representing a 4.3% delta, but this is a professional card with a much higher price point in typical market conditions.

The GPU's 180 W TDP is reasonable for a mobile part of this capability, and the fact that it is listed as an IGP with no power connectors suggests this is a soldered mobile solution rather than a traditional discrete card. The 5 nm process node from TSMC allows for high transistor density of 109.1M per mm², which explains how 57,700 million transistors fit on a 529 mm² die. This efficiency translates directly into the measured frame rates, as the GPU maintains high performance without excessive power draw.

Resolution Scaling

The measured FPS data reveals a predictable scaling pattern as resolution increases from 1080p to 4K, with the GPU becoming the limiting factor at higher resolutions. At the High preset, the average FPS drops from 190 at 1080p to 123 at 1440p (a 35% reduction), and then to 67 at 4K (a 45% reduction from 1440p). This scaling pattern is characteristic of a GPU-bound scenario, where the CPU has ample headroom and the GPU's rendering throughput becomes the bottleneck.

The Low preset shows even more aggressive scaling, with 258 FPS at 1080p dropping to 167 at 1440p (35% reduction) and 90 at 4K (46% reduction from 1440p). The fact that the percentage drop between resolutions is almost identical for both Low and High presets suggests that the GPU is consistently the limiting factor across all settings. If the CPU were the bottleneck, we would expect to see smaller FPS differences at lower resolutions where the CPU has more work to do relative to the GPU.

The Medium preset provides additional insight through its measured minimum FPS values. At 1080p Medium, the average is 225 FPS with a minimum of 191 FPS, indicating a 15% variance between average and minimum. At 1440p Medium, the average is 145 FPS with a minimum of 124 FPS, again a 15% variance. At 4K Medium, the average is 79 FPS with a minimum of 67 FPS, maintaining the same 15% variance. This consistent variance pattern across resolutions further confirms that the GPU is the sole performance limiter, as the frame time distribution remains stable regardless of resolution.

This scaling behavior has practical implications for users. Players with 1440p monitors can confidently use the High preset knowing they will get 123 FPS, while those with 4K displays should consider whether the 67 FPS average at High is sufficient or if the Medium preset's 79 FPS is more appropriate. The data suggests that 1440p is the sweet spot for this combination, offering 123 FPS at High settings with high visual fidelity, while 4K requires a compromise between frame rate and quality.

How This Combo Ranks

The Intel Core Ultra 9 185H and AMD Radeon RX 7900M combination ranks 1226 out of 2930 tested combos for Doom, placing it in the 58th percentile of all tested systems. This ranking is somewhat surprising given the individual component performance, as the RX 7900M ranks in the 94th percentile of all GPUs and the Core Ultra 9 185H ranks in the 85th percentile of all CPUs. The discrepancy between individual component rankings and the combo ranking suggests that this pairing may not be perfectly optimized for Doom specifically, or that the mobile platform introduces thermal or power constraints that limit sustained performance.

The combo rank of 1226 means that approximately 58% of tested systems perform better in Doom, while 42% perform worse. This places the combination in the upper-middle tier of gaming systems, which is respectable but not top-tier. It is notably Doom is a well-optimized game that runs well on a wide range of hardware, so the competition is fierce. Many desktop systems with mid-range GPUs may achieve similar or better frame rates due to higher sustained power delivery and better cooling.

The data indicates that this combo is better suited for high-resolution gaming than for competitive esports at 1080p. At 4K, the combination delivers playable frame rates at Medium settings, which is a significant achievement for a mobile platform. However, at 1080p, the 258 FPS maximum at Low settings is impressive but not extraordinary, as many desktop systems can achieve similar results. The combo's ranking reflects this balanced but not exceptional performance profile.

For users considering this combination, the 1226 rank should be interpreted as a strong mobile gaming solution that excels at 1440p and handles 4K reasonably well. It is not a top-tier competitive gaming machine, but it offers a compelling balance of performance and portability. The measured data suggests that this combo is well-suited for gamers who prioritize visual quality at high resolutions over maximum frame rates at 1080p.

CPU Role

The Intel Core Ultra 9 185H plays a supporting role in this pairing, providing enough processing power to keep the GPU fed without becoming a bottleneck. This CPU features 16 cores and 22 threads based on the Meteor Lake architecture, with a base clock of 3.90 GHz and a boost clock of 5.10 GHz. The 24 MB of shared L3 cache, combined with 2 MB of L2 cache per core, provides ample data locality for game logic and physics calculations.

The CPU's benchmark scores suggest it is a capable gaming processor. The Cinebench R23 multi-core score of 17984.5 and single-core score of 1810.5 indicate strong multi-threaded and single-threaded performance. The Geekbench multi-core score of 11657 and single-core score of 1794 further confirm this assessment. The Passmark multi-thread score of 29376 and single-thread score of 3697 place the CPU in the 85th percentile of all CPUs, which is respectable for a mobile processor.

The CPU's nearest rivals show that it is closely matched with several other mid-range processors. The AMD Ryzen AI 7 PRO 350 scores 35719 with a delta of -0.1%, while the Intel Core 7 250H scores 35728 with a delta of -0.2%. The AMD Ryzen 7 PRO 5845 and AMD Ryzen 7 7700X score 35802 (-0.4%) and 35909 (-0.7%) respectively. These small deltas indicate that the Core Ultra 9 185H is well-positioned within its performance class, with no single rival offering a significant advantage.

In the context of Doom, the CPU's role is primarily to handle game logic, physics, and draw call submission. The measured FPS data shows that at 1080p Low, the system achieves 258 FPS, which is high enough that the CPU could theoretically become a limiting factor if it were weak. However, the consistent FPS scaling across resolutions and settings indicates that the CPU maintains sufficient headroom. The 22 threads and 5.10 GHz boost clock ensure that even the most demanding scenes with many enemies and effects do not cause frame drops due to CPU limitations.

The CPU's 45 W TDP is modest for a 16-core processor, but the Meteor Lake architecture's efficiency ensures that performance remains consistent under sustained gaming loads. The integrated Arc Xe-LPG Graphics with 128 execution units is not relevant for gaming with the discrete RX 7900M present, but it demonstrates the platform's flexibility. The DDR5 memory support with 89.6 GB/s bandwidth ensures that the CPU can quickly access game data, though this is less critical than the GPU's 576.0 GB/s memory bandwidth.

Measured FPS Breakdown

The complete measured FPS data reveals a consistent performance hierarchy across all settings and resolutions. At 1920x1080, the Low preset achieves an average of 258 FPS, which is the highest measured result in the entire dataset. The Medium preset at 1080p delivers 225 FPS with a minimum of 191 FPS and maximum of 258 FPS, showing that the minimum frame rate is still well above the 144Hz refresh rate common on gaming monitors. The High preset at 1080p averages 190 FPS, while the Ultra preset averages 155 FPS, representing a 40% reduction from Low to Ultra at this resolution.

At 2560x1440, the performance scales down proportionally. The Low preset averages 167 FPS, which is 35% lower than at 1080p. The Medium preset averages 145 FPS with a minimum of 124 FPS and maximum of 167 FPS. The High preset averages 123 FPS, while the Ultra preset averages exactly 100 FPS. This 1440p data is particularly important for gamers with high-refresh monitors, as the High preset's 123 FPS is sufficient for 120Hz displays, while the Ultra preset's 100 FPS is better suited for 100Hz or lower refresh rates.

At 3840x2160, the performance drops significantly but remains playable. The Low preset averages 90 FPS, which is 65% lower than the 1080p Low result. The Medium preset averages 79 FPS with a minimum of 67 FPS and maximum of 91 FPS, making it the only 4K preset with measured minimum frame data. The High preset averages 67 FPS, while the Ultra preset averages 54 FPS. The 4K data shows that this combination is capable of 4K gaming, but users should expect to use Medium settings for a consistently smooth experience, as the 67 FPS minimum at Medium is right at the edge of what is acceptable for most players.

The measured data also reveals interesting relationships between presets. At every resolution, the difference between Low and Medium is consistent (33 FPS at 1080p, 22 FPS at 1440p, 11 FPS at 4K), representing roughly 13-15% performance increase from Low to Medium. The difference between Medium and High is 35 FPS at 1080p, 22 FPS at 1440p, and 12 FPS at 4K, again representing 15-18% performance differences. The jump from High to Ultra is the most costly, with a 35 FPS reduction at 1080p, 23 FPS at 1440p, and 13 FPS at 4K. This pattern suggests that the Ultra preset imposes a significant rendering cost that may not be justified by the visual improvements, particularly at lower resolutions where the high frame rates make smoothness more important than subtle visual enhancements.
