Doom

The AMD Ryzen AI Max+ 395 paired with the AMD Radeon RX 7900M delivers a commanding performance profile in Doom, with measured frame rates that consistently exceed display refresh rate targets across most settings and resolutions. The dataset reveals a system that is heavily GPU-bound at higher resolutions, while at 1080p the CPU’s substantial multi-threaded capabilities come to the fore. This analysis breaks down the measured FPS rows, contextualizes the component roles, and answers key questions about how this combination behaves in one of the most optimized shooters of its era.

Settings Recommendations

The measured data for this combo in Doom suggests that the Ultra preset is the optimal choice for players prioritizing visual fidelity without sacrificing playability, provided they are targeting standard 60 FPS displays. At 3840x2160, the Ultra preset delivers an average of 54 FPS, which is below the 60 FPS threshold but still within a range that many consider acceptable for a single-player FPS. However, the data indicates that the High preset at 4K offers a more comfortable experience, yielding 67 FPS on average, which is a 24% increase over Ultra. This makes High the recommended preset for 4K displays, as it maintains a smooth framerate while still providing a significant visual uplift over Medium.

For users on 2560x1440 panels, the choice becomes more nuanced. The Ultra preset produces 100 FPS, which is excellent for high-refresh-rate monitors. The High preset jumps to 123 FPS, offering a 23% improvement. Given that the difference between High and Ultra in Doom is often subtle in fast-paced action, the data favors High as the best balance, providing a 123 FPS average that comfortably drives 120Hz displays. The Medium preset at 145 FPS is also viable, but the step up to High is worth the minor performance cost for the graphical gains.

At 1920x1080, the system is so powerful that even the Ultra preset, with an average of 155 FPS, is the clear recommendation. This frame rate is sufficient for all but the most extreme 240Hz esports displays. The High preset at 190 FPS and Medium at 225 FPS are technically faster, but the visual compromise is unnecessary given the Ultra preset’s high frame rate. The Low preset at 258 FPS is only relevant for competitive play where maximum frame pacing is paramount, but the data suggests that for most users, the graphical fidelity of Ultra is the superior experience. In summary, the ideal preset scales with resolution: High for 4K, High for 1440p, and Ultra for 1080p.

GPU Role

The AMD Radeon RX 7900M is the primary driver of performance in this dataset, particularly as resolution increases. With 16 GB of GDDR6 memory on a 256-bit bus, the GPU provides a substantial 576.0 GB/s of memory bandwidth. This is a critical specification for Doom, which features large, texture-rich environments. The measured frame rates show a clear pattern: as resolution increases from 1080p to 4K, the average FPS drops proportionally, indicating that the GPU’s rendering throughput is the limiting factor.

The GPU’s boost clock of 2090 MHz and base clock of 1825 MHz, combined with 4608 shading units, allow it to maintain high fill rates. This is evident in the 4K results, where the High preset still manages 67 FPS. The GPU’s 192 ROPs contribute to a pixel rate of 401.3 GPixel/s, which is essential for handling the 4K resolution’s pixel count. The data shows a clear scaling pattern: moving from 1080p High (190 FPS) to 1440p High (123 FPS) to 4K High (67 FPS) demonstrates a classic GPU-bound curve, where frame rate is inversely proportional to pixel count.

Interestingly, the GPU’s performance relative to its nearest rivals is strong. The benchmark data places it in the 94th percentile of all GPUs. Compared to the AMD Radeon Pro VII, it is 0.4% faster, and it leads the AMD Radeon Instinct MI60 by 5.4%. While the NVIDIA Quadro RTX 6000 is 4.3% faster in synthetic benchmarks, the RX 7900M’s real-world Doom results show it is more than capable of delivering high frame rates. The 16 GB VRAM is a forward-looking feature, ensuring that texture-heavy games at 4K will not exceed memory capacity, as evidenced by the stable performance across all settings.

CPU Role

The AMD Ryzen AI Max+ 395 is a 16-core, 32-thread processor based on the Zen 5 architecture, with a boost clock of 5.10 GHz. In Doom, which is known for its excellent multi-threading, this CPU provides ample headroom. The data shows that at 1080p, the CPU’s role becomes more prominent. The jump from 190 FPS at High to 258 FPS at Low suggests that at lower settings, the rendering load on the GPU decreases, allowing the CPU to feed frames faster. This is a sign that the processor is not a bottleneck in this configuration.

The CPU’s 64 MB of shared L3 cache and high memory bandwidth of 256.0 GB/s from quad-channel LPDDR5X memory support the rapid data transfer required for high frame rates. Its benchmark scores are impressive, with a Cinebench R23 multi-core score of 35,314 and a single-core score of 2,044. This single-core performance is crucial for the game’s main thread, which handles game logic and physics. The data implies that the CPU can easily handle the game’s simulation at 258 FPS, as the frame rate ceiling at 1080p Low is likely determined by the GPU’s ability to process the reduced workload.

Compared to its nearest CPU rivals, the Ryzen AI Max+ 395 holds its own. It is 1.6% slower than the AMD Ryzen Threadripper PRO 9945WX and 2% faster than the AMD Ryzen 9 8945HX. It is also 1.7% faster than the Intel Core i9-14900K in average benchmark scores. The 55W TDP is notably low for a 16-core part, making this a highly efficient processor for mobile systems. In Doom, the CPU’s contribution is best seen in the 1440p and 1080p results, where the frame rate scaling is not perfectly linear with resolution, indicating that the CPU is keeping pace with the GPU’s output.

Resolution Scaling

The measured FPS data reveals a classic resolution scaling pattern that highlights the GPU-bound nature of this configuration. At the High settings preset, the frame rates are 190 FPS at 1920x1080, 123 FPS at 2560x1440, and 67 FPS at 3840x2160. This represents a 35% drop from 1080p to 1440p, and a further 45% drop from 1440p to 4K. The scaling is nearly linear with the pixel count increase: 1440p has 1.78 times the pixels of 1080p, and 4K has 2.25 times the pixels of 1440p. The observed drops are consistent with these ratios, confirming that the GPU’s pixel throughput is the bottleneck.

This scaling behavior is consistent across all settings. The Low preset shows 258 FPS at 1080p, 167 FPS at 1440p, and 90 FPS at 4K. The percentage drops are similar, reinforcing that the GPU is the limiting component. However, the absolute frame rates at 1080p are exceptionally high, which suggests that the CPU’s 5.10 GHz boost clock and 32 threads are more than sufficient to feed the GPU. If the CPU were the bottleneck, we would expect to see a plateau in FPS at lower resolutions, where the GPU has less work to do. Instead, the frame rates continue to climb as resolution decreases, indicating that the GPU is always the limiting factor, even at 1080p.

The data also shows that the scaling from 1440p to 4K is slightly steeper than from 1080p to 1440p. For example, the Medium preset drops from 145 FPS at 1440p to 79 FPS at 4K, a 45% reduction. This is likely due to the increased memory bandwidth pressure at 4K, where the 576.0 GB/s bandwidth is being utilized more heavily. Overall, the resolution scaling analysis confirms that this is a high-performance mobile GPU that scales predictably, making it suitable for all three resolutions, albeit with settings adjustments at 4K.

Measured FPS Breakdown

The complete dataset of measured frame rates provides a detailed picture of performance across all tested configurations.

At 1920x1080, the system delivers exceptional performance. The Low preset achieves an average of 258 FPS, with the Medium preset at 225 FPS, showing a minimum of 191 FPS and a maximum of 258 FPS. The High preset averages 190 FPS, while the Ultra preset still delivers a very high 155 FPS. These numbers indicate that at 1080p, the combination is capable of driving any high-refresh-rate monitor on the market, with even the most demanding settings producing frame rates well above 144 FPS.

At 2560x1440, the performance remains impressive. The Low preset averages 167 FPS, followed by Medium at 145 FPS (with a minimum of 124 FPS and maximum of 167 FPS). The High preset averages 123 FPS, and the Ultra preset averages 100 FPS. This resolution is the sweet spot for this combo, as it allows for high refresh rates on all presets, with Ultra still breaking the 100 FPS barrier. The data shows that 1440p High is a particularly balanced choice, offering both high frame rates and high visual quality.

At 3840x2160, the performance begins to show the GPU’s limits. The Low preset manages an average of 90 FPS, which is playable. The Medium preset averages 79 FPS, with a minimum of 67 FPS and maximum of 91 FPS. The High preset averages 67 FPS, which is just above the 60 FPS standard. The Ultra preset drops to an average of 54 FPS, which may be acceptable for some but is not ideal for fast-paced action. The 4K data suggests that users should stick to High or below for a consistent experience, as the jump from High to Ultra incurs a 19% performance penalty.

How This Combo Ranks

The combined system of the AMD Ryzen AI Max+ 395 and AMD Radeon RX 7900M achieves a rank of 1226 out of 2930 tested combinations in Doom, placing it in the 58th percentile of all configurations. This is a solid mid-to-high tier ranking, but it is not at the very top of the leaderboard. The data implies that while this combo is very capable, there are many other systems with faster GPUs or more optimized pairings that can achieve higher frame rates.

Given that the GPU is the primary bottleneck in this game, the ranking is likely more influenced by the RX 7900M’s position in the GPU hierarchy than the CPU’s performance. The GPU ranks in the 94th percentile of all GPUs, but its nearest rivals in synthetic benchmarks, such as the NVIDIA Quadro RTX 6000, show that it is not the absolute fastest mobile GPU. The CPU’s ranking in the 95th percentile of all CPUs suggests that the processor is less likely to be the cause of the combo’s mid-tier ranking. Instead, the data points to the GPU’s raw rasterization power as the limiting factor, which is consistent with the resolution scaling analysis.

The rank of 1226 out of 2930 is a strong result for a mobile platform, especially one with a 55W CPU and 180W GPU. The fact that this combo outperforms 58% of all tested systems, including many desktop configurations, reflects the efficiency of the Zen 5 architecture and RDNA 3.0. However, for users seeking the absolute highest frame rates in Doom, the data suggests that a system with a higher-tier GPU would be necessary to break into the top quartile of performance. For most users, this combo offers a premium experience that is well above average, particularly at 1440p and 1080p.
