Doom

The AMD Ryzen AI Max+ 395 and NVIDIA GeForce RTX 4080 combination delivers remarkably high frame rates in Doom, a 2016 FPS title that remains highly playable on modern hardware. The data shows a system that is overwhelmingly GPU-bound at higher resolutions but capable of pushing well past 200 FPS at 1080p, making it an excellent choice for high-refresh-rate displays.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen AI Max+ 395 is a 16-core, 32-thread processor based on the Zen 5 architecture, with a base clock of 3.00 GHz and a boost clock of 5.10 GHz. This mobile-class chip, built on TSMC's 4 nm process, features a 64 MB shared L3 cache and supports quad-channel LPDDR5X memory with 256.0 GB/s of bandwidth. While Doom is not a heavily multithreaded title by modern standards, the CPU's high single-thread performance is crucial for maintaining high frame rates, as the game's engine relies on a primary simulation thread.

Benchmark results indicate the CPU's strengths. In Cinebench R23, it scores 35,314 in multi-core and 2,044 in single-core tests. Geekbench results show 20,992 multi-core and 2,464 single-core scores. The PassMark single-thread score of 4,147, combined with a physics score of 3,481, suggests robust per-core performance that can handle the game's logic without becoming a bottleneck. At 1080p resolution, where the GPU has less work per frame, the CPU's ability to feed frames quickly is directly reflected in the measured FPS, reaching up to 288 FPS on Low settings.

The CPU's performance percentile vs. all CPUs is 95, placing it in the top 5% of processors. Its nearest rivals include the AMD Ryzen Threadripper PRO 9945WX (1.6% higher average score), AMD EPYC Embedded 8224P (1.6% higher), and Intel Core i9-14900K (1.7% lower). The Ryzen AI Max+ 395's 32 threads are more than sufficient for Doom, which rarely scales beyond a few cores. The data suggests that in this game, the CPU's role is to provide consistently high single-thread throughput, which it does admirably, allowing the RTX 4080 to operate at its full potential without waiting on the processor.

Settings Recommendations — which preset gives the best experience per the measured rows

The measured FPS data provides clear guidance on which settings preset offers the best balance of visual quality and performance. At 1080p, the jump from Medium to High is significant, with average FPS dropping from 251 to 212, a 15.5% reduction. However, the jump from High to Ultra is more severe, dropping from 212 to 173 FPS, a further 18.4% reduction. For players with 144 Hz monitors, the High preset at 1080p, delivering 212 FPS, provides a substantial headroom above the refresh rate, ensuring smooth gameplay even during intense scenes.

At 1440p, the High preset yields 137 FPS, which is still above the 120 Hz threshold and comfortably playable on most high-refresh panels. The Medium preset at 162 FPS offers a 18.2% improvement over High, making it an attractive option for those who prioritize frame rate over minor visual fidelity differences. The Ultra preset at 112 FPS, while still playable, begins to dip below the 120 FPS mark, making it less ideal for competitive play. The data suggests that High settings at 1440p provide the best overall experience, balancing the visual enhancements against the need for high, consistent frame rates.

At 4K, the situation changes dramatically. The High preset delivers 74 FPS, while Medium provides 88 FPS, a 18.9% improvement. Low settings yield 101 FPS, which is 36.5% higher than High. The Ultra preset drops to 61 FPS, which may be below the refresh rate of many 4K displays and could introduce noticeable stuttering. For 4K gaming, the Medium preset at 88 FPS is the recommended choice, as it maintains a playable frame rate while retaining a reasonable level of visual detail. The data indicates that the performance cost of Ultra settings is disproportionately high at this resolution, making it the least efficient preset.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The FPS scaling across resolutions clearly identifies the GPU as the primary limiting component in this system. Moving from 1080p to 1440p on High settings, the average FPS drops from 212 to 137, a 35.4% reduction. Scaling further to 4K, the average FPS drops to 74, a 46.0% reduction from 1440p and a 65.1% reduction from 1080p. This pattern is consistent across all settings presets, indicating that the workload is scaling as expected with pixel count, which is a classic sign of GPU-bound performance.

At 1080p Low settings, the system achieves 288 FPS. This high frame rate suggests that the CPU is capable of feeding the GPU at very high rates, as the RTX 4080 is not fully saturated at this resolution and setting combination. The fact that the FPS does not scale linearly with resolution — for example, 4K has 4 times the pixels of 1080p but the FPS does not drop to a quarter — indicates that the GPU still has headroom, but the scaling is steep enough to confirm its dominance. The 16 GB of GDDR6X memory on the RTX 4080, with 716.8 GB/s of bandwidth, is likely sufficient for Doom at all resolutions, as the game is from 2016 and does not require large texture pools.

The data reveals that the system's performance is well-balanced, with the CPU providing enough throughput to avoid becoming a bottleneck at lower resolutions. At 4K, the GPU's raw compute power, measured at 48.74 TFLOPS FP32, becomes the deciding factor. The frame rate differences between settings at each resolution are consistent, suggesting that the GPU's shading units, TMUs, and ROPs are the primary contributors to the performance scaling, rather than any CPU-side limitation.

The combo's rank of 910 suggests that the RTX 4080, while powerful, is not the absolute fastest GPU available, and the CPU, despite its high benchmark scores, is not the top performer in single-threaded tasks. The data shows that the combo is capable of delivering excellent frame rates, but there are other combos that push even higher, particularly at 1080p where the CPU's single-thread performance becomes more critical. The RTX 4080's nearest rivals include the RTX 4080 SUPER (0.1% higher average score), which likely contributes to some combos ranking higher.

The ranking reflects the balance of the components. While the Ryzen AI Max+ 395 has a high multi-core score, its single-thread score of 2,044 in Cinebench R23 is good but not exceptional. In a game like Doom, which is not heavily multithreaded, the CPU's single-thread performance directly impacts the maximum achievable FPS. The combo's position in the rankings suggests that systems with CPUs that have higher single-thread scores, paired with similarly powerful GPUs, can achieve higher frame rates, particularly at 1080p.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 4080 is the dominant component in this system for Doom's performance. This GPU, based on the Ada Lovelace architecture and the AD103 chip, features 9,728 shading units, 304 texture mapping units, and 112 raster output pipelines. Its base clock is 2205 MHz with a boost clock of 2505 MHz. The GPU is equipped with 16 GB of GDDR6X memory on a 256-bit bus, providing 716.8 GB/s of memory bandwidth. These specifications are more than sufficient for Doom, which was released in 2016 and does not demand the same level of GPU resources as modern titles.

The GPU's benchmark scores show its overall capability. In 3DMark Steel Nomad DX12, it scores 6,567, and its PassMark G3D score is 34,457, placing it in the 86th percentile vs. all GPUs. Its nearest rivals are the RTX 4080 SUPER (0.1% higher average score), AMD Radeon Pro W5700X (1.1% lower), AMD Radeon RX 6750 GRE 12 GB (2.6% lower), and AMD Radeon 8060S (2.7% lower). The GPU's high memory bandwidth and large cache are crucial for maintaining high frame rates at 4K, where texture fetching and memory access patterns become more demanding.

The data shows that the GPU is the primary bottleneck at higher resolutions. At 4K Ultra, the system achieves 61 FPS, which is a 64.7% reduction from the 1080p Ultra score of 173 FPS. This scaling is directly attributable to the GPU's compute throughput and memory bandwidth. The RTX 4080's 48.74 TFLOPS FP32 performance is substantial, but Doom's rendering workload at 4K pushes the GPU to its limits. The 16 GB VRAM is not a limiting factor, as the game's highest texture settings do not require more than 8 GB, leaving ample headroom.
