Doom

The AMD Ryzen AI Max+ 395 paired with the NVIDIA GeForce RTX 5090 delivers a performance profile in Doom that is heavily dictated by resolution. The measured frame rates reveal a system that is overwhelmingly GPU-bound at 4K, but shifts toward a more balanced, CPU-influenced state at lower resolutions. This analysis walks through the data step by step, examining how the components interact with the game's engine.

Resolution Scaling

The frame rate scaling from 1920x1080 to 3840x2160 is steep, indicating a clear transition in the bottleneck. At 1920x1080 with High settings, the combo produces 243 FPS. Moving to 2560x1440 at the same settings drops the average to 157 FPS, a reduction of 86 FPS. Further scaling to 3840x2160 yields 85 FPS, which is 158 FPS lower than the 1080p result. This trajectory demonstrates that the pixel throughput demand at 4K heavily taxes the GPU, while at 1080p, the frame rate is high enough to suggest the CPU is doing more of the heavy lifting.

Looking at the Low preset, the pattern holds. At 1920x1080, the average is 330 FPS. At 2560x1440, it falls to 214 FPS, and at 3840x2160, it reaches 116 FPS. The percentage drop from 1080p to 1440p is roughly 35%, while the drop from 1440p to 4K is about 46%. This non-linear scaling is characteristic of a GPU that is being saturated by the increasing resolution, but the fact that the 4K Low score (116 FPS) is still higher than the 4K High score (85 FPS) shows that the GPU's workload is significantly reduced by lowering settings.

The data suggests that at 4K, the RTX 5090 is the limiting component. The difference between Low (116 FPS) and Ultra (70 FPS) at 3840x2160 is 46 FPS, a massive spread that highlights how sensitive the GPU is to pixel and shading complexity. At 1920x1080, the spread between Low (330 FPS) and Ultra (198 FPS) is 132 FPS, but the absolute numbers are so high that the CPU's role becomes more prominent. The engine's ability to push beyond 300 FPS at 1080p Low indicates a well-optimized title, but the scaling pattern points to the GPU as the primary constraint for most playable configurations.

GPU Role

The NVIDIA GeForce RTX 5090 is the dominant force in this configuration, and its specifications directly explain the measured outcomes. With 32 GB of GDDR7 memory on a 512-bit bus, the card offers a memory bandwidth of 1.79 TB/s. This immense bandwidth is crucial for feeding the 21760 shading units at high resolutions. The boost clock of 2407 MHz, paired with 176 ROPs, provides the raw compute necessary for the high frame rates observed.

The card's FP32 performance is rated at 104.8 TFLOPS, which is a theoretical metric, but the benchmark results confirm its practical capability. In Doom, the GPU's role is most evident at 3840x2160. At this resolution, the card averages 85 FPS on High settings, but when the preset is dropped to Low, the average jumps to 116 FPS. This 31 FPS improvement shows that the GPU is not fully saturated even at 4K, as reducing the shading load yields a substantial gain. The Ultra preset at 4K drops to 70 FPS, indicating that the most demanding settings introduce significant overhead.

The GPU's performance relative to its nearest rivals is interesting. The data shows the RTX 5090 has an average benchmark score of 79842, placing it in the 92nd percentile of all GPUs. Its nearest rival, the NVIDIA Tesla P100 PCIe 16 GB, scores 79605, a delta of just 0.3%. This suggests that in synthetic tests, the 5090 is only marginally ahead of that compute-oriented card. However, in Doom, the architectural advantages of the Blackwell 2.0 design, such as the dedicated RT cores and tensor cores, likely contribute to the game-specific performance, though the measured FPS data is the only evidence we have for this title. The 32 GB VRAM is also a notable asset, as it prevents any potential memory capacity bottlenecks at 4K with high-resolution textures.

How This Combo Ranks

The combination of the AMD Ryzen AI Max+ 395 and the NVIDIA GeForce RTX 5090 holds a combo rank of 584 out of 2930 tested combinations in Doom. This places it in the top 20% of all tested pairings, which is a strong showing given the CPU's mobile-oriented design. The ranking reflects that while the GPU is a top-tier part, the CPU's performance ceiling may prevent the combo from reaching the very top of the charts.

To contextualize this rank, consider the CPU's synthetic performance. The Ryzen AI Max+ 395 has an average benchmark score of 77740, placing it in the 95th percentile of all CPUs. Its nearest rival is the Intel Core i9-14900K, which scores 79097, a delta of -1.7% for the AMD chip. This indicates the 395 is slightly behind a flagship desktop CPU in general compute tasks. In Doom, this translates to a combo that is powerful but not the absolute fastest. The rank of 584 suggests that there are 583 other combinations that achieve higher average FPS in this specific game, likely involving desktop CPUs with higher single-thread performance or higher boost clocks.

The data shows that the combo is not bottlenecked by the GPU in most scenarios, as the RTX 5090 is a top-tier part. Instead, the CPU's Zen 5 architecture, while efficient, may not deliver the same peak frame rates as the highest-end desktop chips when the GPU is not the limiting factor. The 16 cores and 32 threads are ample for modern games, but Doom's engine may favor higher clock speeds over core count. The boost clock of 5.10 GHz is respectable, but the core configuration and memory bandwidth of 256.0 GB/s for the CPU's LPDDR5X memory might be the constraining factor at 1080p.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across three resolutions and four settings presets. At 1920x1080, the combo delivers high frame rates across the board. The Low preset averages 330 FPS, with Medium at 287 FPS and High at 243 FPS. The Ultra preset averages 198 FPS. The Medium preset has recorded minimum and maximum values of 244 FPS and 331 FPS, respectively, showing a stable frame delivery with a narrow band around the average.

Moving to 2560x1440, the averages decrease but remain highly playable. Low settings yield 214 FPS, Medium produces 186 FPS, and High reaches 157 FPS. Ultra drops to 128 FPS. The Medium preset shows a minimum of 158 FPS and a maximum of 214 FPS, indicating that the frame pacing remains consistent even as the resolution increases. The gap between Low and Ultra is 86 FPS, demonstrating the GPU's sensitivity to settings at this resolution.

At 3840x2160, the performance is still strong but demands more careful settings selection. Low averages 116 FPS, Medium averages 101 FPS, and High drops to 85 FPS. Ultra is the most demanding, averaging 70 FPS. The Medium preset has a minimum of 86 FPS and a maximum of 116 FPS. The data shows that even at 4K, the combo can maintain playable frame rates on High settings, but for a smoother experience, Medium or Low would be preferable.

The differences between presets are consistent across resolutions. The jump from Low to Medium costs roughly 10-15% performance, while the jump from High to Ultra costs around 15-20%. This suggests that the Ultra preset introduces effects that are disproportionately expensive relative to the visual gain, while Medium and High offer a more balanced trade-off.

Settings Recommendations

Based on the measured data, the optimal settings depend on the target resolution and refresh rate. For users with a 1920x1080 display, the High preset at 243 FPS is an excellent choice, offering a high level of visual fidelity while still exceeding the refresh rate of most monitors. The Ultra preset at 198 FPS is also viable, but the 45 FPS drop from High may not be worth the visual upgrade unless the user has a very high refresh rate display.

At 2560x1440, the Medium preset provides 186 FPS, which is a sweet spot for performance and quality. The High preset at 157 FPS is also excellent, and the data shows that the gap between Medium and High is 29 FPS. For a 144Hz monitor, High is the better pick, as it stays above the refresh rate. The Ultra preset at 128 FPS is still playable but may show dips below 144Hz.

At 3840x2160, the Medium preset is the recommended choice, averaging 101 FPS. This provides a good balance, as the Low preset (116 FPS) sacrifices too much visual quality, while High (85 FPS) and Ultra (70 FPS) may not achieve the smoothness desired on a high-end display. The Medium preset's minimum of 86 FPS ensures that frame drops remain above 60 FPS, making it the safest option for a consistent 4K experience.

CPU Role

The AMD Ryzen AI Max+ 395 plays a supporting role in this configuration, but its impact is still measurable. With 16 cores and 32 threads based on the Zen 5 architecture, the CPU provides ample parallelism for modern game engines. The base clock of 3.00 GHz and boost clock of 5.10 GHz are respectable, and the 64 MB of shared L3 cache helps reduce memory latency.

In Doom, the CPU's role becomes more apparent at lower resolutions. At 1920x1080 on Low settings, the combo reaches 330 FPS, which is a high enough frame rate that the CPU's ability to feed the GPU becomes a factor. The CPU's single-thread performance, as indicated by its Geekbench single-core score of 2464, is strong, but it may lag behind the very best desktop CPUs. The data shows that the CPU's nearest rival, the Intel Core i9-14900K, has a higher average benchmark score (79097 vs 77740), suggesting it has a slight edge in compute tasks that could translate to higher frame rates in CPU-bound scenarios.

The CPU's memory bandwidth of 256.0 GB/s, while high for a mobile part, is lower than what a desktop platform with dedicated memory might offer. This could potentially limit performance in scenarios where the CPU is fetching large amounts of data. However, the benchmark results show that the combo still achieves high frame rates, so any limitation is not severe. The CPU's percentile rank of 95 indicates it is a top-tier processor, and its performance in Doom is sufficient to keep the RTX 5090 well-fed at most resolutions, with the exception of the highest frame rate scenarios at 1080p.
