Doom

Doom’s 2016 engine is famously scalable, and the data for the AMD Ryzen AI Max+ 395 paired with the NVIDIA GeForce RTX 4060 Mobile confirms a wide performance envelope across resolutions and presets. At 1080p Low, the combo averages 203 FPS, while at 4K Ultra it drops to 43 FPS. This 4.7x spread highlights a system that transitions from being GPU-bound at high resolutions to increasingly CPU-bound at lower ones, though the RTX 4060 Mobile remains the primary limiter in most scenarios.

Resolution Scaling

The FPS deltas between resolutions are steep and consistent. Moving from 1080p to 1440p at High settings reduces the average from 149 FPS to 97 FPS, a 35% drop. Pushing further to 4K High yields 52 FPS, another 46% reduction from the 1440p figure. This scaling pattern is classic for a GPU with an 8 GB frame buffer and a 128-bit memory interface; the pixel throughput demand at 4K simply overwhelms the 4060 Mobile’s 11.61 TFLOPS of FP32 compute.

At Low settings, the resolution scaling is even more revealing. The jump from 1080p Low (203 FPS) to 1440p Low (131 FPS) costs 35% performance, and then 4K Low (71 FPS) is another 46% lower. The fact that 4K Low still only hits 71 FPS, despite the CPU’s 16 cores and 5.10 GHz boost clock, proves the GPU is the bottleneck. If the CPU were limiting, the gap between 1440p and 4K would shrink dramatically; instead, it remains proportional to the pixel count increase.

Medium settings show a similar trend with a smaller dataset. 1080p Medium averages 177 FPS, 1440p Medium drops to 114 FPS (–36%), and 4K Medium lands at 62 FPS (–46%). The consistency of these percentage drops across all three presets indicates a well-balanced scaling model where the GPU’s fill rate and memory bandwidth are the dominant constraints above 1080p.

Ultra settings are the most demanding, with 1080p Ultra at 122 FPS, 1440p Ultra at 79 FPS (–35%), and 4K Ultra at 43 FPS (–46%). These figures suggest that Ultra’s additional effects, such as higher shadow resolution and volumetric lighting, tax the GPU’s ROPs and texture units proportionally. The 90.72 GPixel/s pixel rate and 181.4 GTexel/s texture rate are simply insufficient for 4K Ultra’s workload.

The takeaway for resolution scaling is clear: this combo is a 1080p and 1440p machine for Doom. At 4K, even Low settings cannot maintain a 60 FPS average (71 FPS is close but not locked), and Medium dips to 62 FPS. The 256.0 GB/s memory bandwidth shared by both the CPU and GPU (the CPU’s quad-channel LPDDR5X and the GPU’s 128-bit GDDR6 both peak at this figure) is a notable constraint at higher resolutions.

CPU Role

The AMD Ryzen AI Max+ 395 is a high-end mobile processor with 16 cores and 32 threads based on Zen 5 architecture. Its base clock of 3.00 GHz and boost clock of 5.10 GHz provide substantial single-thread headroom, which Doom’s id Tech 6 engine benefits from. The CPU’s benchmark scores support this: a Geekbench single-core score of 2464 and a Cinebench R23 single-core score of 2044 place it in the 95th percentile of all CPUs.

In Doom, the CPU’s role is most evident at 1080p Low, where the GPU has less work per frame. The 203 FPS average indicates the Ryzen AI Max+ 395 can feed frames faster than the RTX 4060 Mobile can render them at this resolution. The 64 MB of shared L3 cache helps maintain high minimum frame rates, though min FPS data is only available for Medium settings: 150 FPS at 1080p, 97 FPS at 1440p, and 53 FPS at 4K.

The CPU’s multi-threaded capability, reflected in a Cinebench R23 multi-core score of 35314 and a Passmark multithread score of 54934, is overkill for Doom. The game rarely scales beyond a few threads, so the 16 cores are not fully utilized. However, the high single-core performance ensures that the game’s main thread does not become a bottleneck until very high frame rates. The nearest CPU rival, the Intel Core i9-14900K, has a 1.7% higher average benchmark score, but in Doom’s measured results, the AMD chip’s 5.10 GHz boost clock is sufficient to avoid limiting the GPU at 1440p and above.

The CPU’s 55 W TDP and 4 nm process node (TSMC) mean it runs efficiently, but the data shows no thermal throttling impact on frame rates. At 1080p High, the 149 FPS average is likely near the ceiling of what this CPU can feed to the GPU in this title. The fact that 1080p Low (203 FPS) is 36% higher than 1080p High (149 FPS) suggests the GPU is still the primary limiter even at 1080p, as the CPU has more headroom to push beyond 203 FPS if the GPU could render faster.

GPU Role

The NVIDIA GeForce RTX 4060 Mobile is an Ada Lovelace chip with 3072 shading units, 96 TMUs, and 48 ROPs. Its 8 GB of GDDR6 memory on a 128-bit bus provides 256.0 GB/s of bandwidth, identical to the CPU’s memory bandwidth. This symmetry is interesting, but in practice, the GPU’s bandwidth is the limiting factor at higher resolutions. The GPU’s Passmark G3D score of 17469 places it in the 67th percentile of all GPUs, with nearest rivals including the desktop RTX 2080 (–0.7% delta) and the Intel Arc B580 (–1.3% delta).

The GPU’s clock speeds are 1545 MHz base and 1890 MHz boost. These clocks, combined with the 48 ROPs, yield a pixel rate of 90.72 GPixel/s. In Doom, this translates to 122 FPS at 1080p Ultra, but only 43 FPS at 4K Ultra. The 4K Ultra result is particularly telling: the 8 GB VRAM is likely saturated with Ultra textures and high-resolution assets, causing the GPU to struggle with memory allocation and bandwidth contention.

The RTX 4060 Mobile’s FP32 throughput of 11.61 TFLOPS is modest by modern standards. This limits raw shader performance, which is why the 4K High (52 FPS) and 4K Medium (62 FPS) results are below 60 FPS. The GPU’s 24 RT cores and 96 tensor cores are present but irrelevant for Doom, which does not use ray tracing or DLSS in these measurements. The Passmark DirectX 12 score of 73 and DirectX 11 score of 157 indicate the GPU’s API performance is adequate, but the game’s Vulkan path (supported via API version 1.4) is where the data likely comes from.

The GPU’s nearest rival comparison shows it is slightly behind the RTX 2080 (by 0.7%) and slightly ahead of the RX 7700 XT (by 0.8%) in average benchmark scores. In Doom specifically, the 4060 Mobile’s 8 GB VRAM is sufficient for 1080p and 1440p, but at 4K, the frame buffer becomes a constraint. The measured FPS at 4K Ultra (43 FPS) is exactly half of the 1080p Ultra (122 FPS), suggesting a linear scaling failure due to memory bandwidth rather than compute.

Measured FPS Breakdown

1080p (1920x1080): The lowest resolution shows the highest frame rates. Low settings produce 203 FPS average, which is exceptional for any hardware. Medium settings average 177 FPS with a minimum of 150 FPS and maximum of 203 FPS. High settings drop to 149 FPS, and Ultra settings yield 122 FPS. All four presets exceed 120 FPS, making 1080p ideal for high-refresh-rate monitors.

1440p (2560x1440): This resolution is the sweet spot for visual fidelity versus performance. Low settings average 131 FPS, Medium averages 114 FPS (min 97, max 132), High averages 97 FPS, and Ultra averages 79 FPS. The step from High to Ultra costs 18 FPS, which is a 19% reduction. Every preset except Ultra maintains at least 97 FPS, comfortably above 60 FPS.

4K (3840x2160): This resolution challenges the combo significantly. Low settings average 71 FPS, which is playable but not locked to 60. Medium averages 62 FPS with a minimum of 53 FPS, meaning stutters can occur. High averages 52 FPS, and Ultra drops to 43 FPS. Only Low settings provide a consistent 60+ FPS experience at 4K, and even then, the margin is thin.

The data shows that the Medium preset is the only one with min FPS measurements across all resolutions: 150 FPS at 1080p, 97 FPS at 1440p, and 53 FPS at 4K. These minimums are 85%, 85%, and 85% of their respective averages, indicating consistent frame pacing without severe drops. The lack of min FPS data for other presets suggests they were either perfectly stable or the measurement was omitted, but the Medium data points to a well-optimized settings profile.

FAQ

Q: Can this laptop combo run Doom at 4K 60 FPS?

A: No. The highest 4K average is 71 FPS on Low settings, but Medium drops to 62 FPS (min 53) and High to 52 FPS. Ultra is 43 FPS. To maintain 60 FPS at 4K, you must use Low settings, and even then, the margin is only 11 FPS.

Q: What is the best resolution for a 144Hz display?

A: At 1080p, all presets exceed 120 FPS, with Low hitting 203 FPS. At 1440p, Low (131 FPS) and Medium (114 FPS) can drive a 144Hz panel, but High (97 FPS) and Ultra (79 FPS) cannot. For 144Hz, stick to 1080p with any preset or 1440p with Medium or lower.

Q: Is the CPU or GPU the bottleneck in Doom?

A: The GPU is the primary bottleneck at all resolutions above 1080p Low. The CPU’s 16 cores and 5.10 GHz boost clock are sufficient to push 203 FPS at 1080p Low, but the RTX 4060 Mobile’s 8 GB VRAM and 128-bit bus limit higher resolutions. At 1080p High, the 149 FPS average suggests the GPU is still limiting, as the CPU could likely feed more frames.

Q: How does the RTX 4060 Mobile compare to a desktop RTX 2080 in Doom?

A: The RTX 4060 Mobile has an average benchmark score 0.7% lower than the RTX 2080. In Doom’s measured results, this translates to similar performance, though the 4060 Mobile’s 8 GB VRAM may cause slightly lower 4K performance due to bandwidth constraints. The GPU’s Passmark G3D score of 17469 is nearly identical to the RTX 2080’s 22895 average, within the 0.7% delta.

Q: What settings preset should be avoided at 1440p?

A: Ultra at 1440p averages 79 FPS, which is playable but below the 97 FPS of High. The 18 FPS cost for Ultra’s visual improvements is steep. For a smoother experience, High at 1440p provides 97 FPS, which is 23% faster than Ultra.

Q: Does the CPU’s 64 MB L3 cache help Doom’s minimum frame rates?

A: The data shows min FPS only for Medium presets: 150 FPS at 1080p, 97 FPS at 1440p, and 53 FPS at 4K. These are 85% of the average FPS, indicating solid frame pacing. While the L3 cache likely contributes to this stability, the exact impact cannot be isolated from the measured data.

Settings Recommendations

For a 60 FPS target at 4K, the data dictates Low settings, which average 71 FPS. Medium at 4K is borderline with a 62 FPS average but a 53 FPS minimum, risking noticeable drops. If you prefer visual quality over raw frame rate, Medium is acceptable, but Low is the only preset that guarantees a stable 60+ FPS experience at 4K.

At 1440p, High settings provide the best balance of visual fidelity and performance, averaging 97 FPS. This is 18 FPS slower than Medium (114 FPS) but offers better textures and effects. Ultra at 1440p (79 FPS) is the only preset that dips below 90 FPS, so it is recommended only if you prioritize image quality over smoothness. For competitive play, Medium at 1440p (114 FPS) or Low (131 FPS) are better choices.

At 1080p, all presets are viable. Ultra (122 FPS) delivers the best visuals while still exceeding 120 FPS, making it the recommended preset for this resolution. High (149 FPS) and Medium (177 FPS) are also excellent for high-refresh displays. Low (203 FPS) is only necessary for 240Hz panels or if you want maximum headroom for streaming or background tasks.

The combo’s overall rank in Doom is 2270 out of 3712 tested combinations, placing it in the 61st percentile. This is a mid-to-upper tier result, reflecting the GPU’s 67th percentile standing and the CPU’s 95th percentile. The GPU is the limiting factor, so prioritizing lower resolutions or reduced settings will yield the largest FPS gains. For the best experience, 1440p High is the recommended sweet spot, offering 97 FPS with good visuals, while 1080p Ultra is optimal for high-refresh gaming.
