GPU Role

The NVIDIA GeForce RTX 4080 is the dominant component in this pairing for Doom's frame rate output. Built on the Ada Lovelace architecture with a 5 nm process from TSMC, the GPU contains 45,900 million transistors on a 379 mm² die. Its base clock is 2205 MHz with a boost clock of 2505 MHz, and it operates at a TDP of 320 W. The memory subsystem is particularly relevant for a fast-paced FPS like Doom: 16 GB of GDDR6X on a 256-bit bus yields 716.8 GB/s of bandwidth. This bandwidth allows the GPU to feed its 9728 shading units, 304 texture mapping units, and 112 ROPs without stalling on texture fetches.

In benchmark terms, the RTX 4080 scores 34457 in Passmark G3D and 20671 in Passmark GPU Compute, placing it in the 86th percentile of all GPUs. Its average benchmark score is 54247. The nearest rival, the NVIDIA GeForce RTX 4080 SUPER, scores 54209, a delta of 0.1 percent. The AMD Radeon Pro W5700X trails by 1.1 percent with a score of 54828, while the AMD Radeon RX 6750 GRE 12 GB is 2.6 percent behind at 55698. These close margins in aggregate benchmarks, however, do not directly translate to Doom's specific engine demands, where the measured FPS data shows the GPU scaling strongly with resolution changes.

The GPU's pixel rate of 280.6 GPixel/s and texture rate of 761.5 GTexel/s are the raw throughput figures that govern fill-rate-limited scenes. In Doom, which features fast movement and frequent environmental destruction, these rates help maintain consistent frame pacing. The 48.74 TFLOPS of FP32 compute power also supports the game's dynamic lighting and particle effects. At 4K Ultra, the combo drops to 61 FPS average, indicating the GPU is approaching its limit with maximum settings at that resolution. The RTX 4080's DirectX 12 Ultimate support (12_2) and Vulkan 1.4 API compatibility align well with Doom's engine, which can leverage modern graphics APIs for reduced CPU overhead.

CPU Role

The Intel Core Ultra 7 155H provides the processing foundation for this combo. This mobile processor from the Core Ultra Series 1, codenamed Meteor Lake, is fabricated on Intel's 7 nm process. It houses 16 cores and 22 threads, with a base clock of 3.80 GHz and a boost clock of 4.80 GHz. The TDP is 28 W, which is modest for a gaming laptop CPU, but the architecture compensates with efficiency. The cache hierarchy includes 112 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3 cache. Memory support is DDR5 with a dual-channel bus providing 89.6 GB/s of bandwidth.

In synthetic benchmarks, the CPU scores 15028 in Cinebench R23 multi-core and 1743 in single-core. Passmark results show 24873 in multithread and 3468 in single-thread tests. The CPU's average benchmark score is 32697, placing it in the 83rd percentile of all CPUs. Its nearest rival, the Intel Core i5-14600T, scores 32707 with a delta of 0 percent. The AMD Ryzen AI 7 PRO 360 is 0.1 percent ahead at 32662, while the AMD Ryzen 5 7400F trails by 0.2 percent at 32750. These close margins indicate the 155H sits in a competitive mid-range position for CPU performance.

For Doom, the CPU's role is less critical than the GPU at higher resolutions, but it still matters at lower settings. At 1080p Low, the combo achieves 288 FPS average, which suggests the CPU can feed the GPU sufficiently at high frame rates. The 22 threads allow background tasks and game logic to run concurrently without introducing stutter. The Passmark physics score of 1727 and integer math score of 86870 indicate solid computational throughput for game physics and AI calculations. The CPU's integrated Arc Xe-LPG 128EU graphics are not used in this configuration, but their presence means the discrete GPU receives no competition for system resources. The boost clock of 4.80 GHz provides the single-thread performance needed for Doom's main game loop, which is typically bound to one or two cores.

How This Combo Ranks

The combination of the Intel Core Ultra 7 155H and NVIDIA GeForce RTX 4080 achieves a rank of 1222 out of 3712 tested hardware combinations for Doom. This places the combo in the 67th percentile of all tested configurations, meaning roughly two-thirds of tested combos perform worse and one-third perform better. The rank reflects the balance between the CPU's mid-range position (83rd percentile among CPUs) and the GPU's strong position (86th percentile among GPUs). The gap between the CPU and GPU percentile rankings is small, but the GPU's slightly higher standing suggests it is the more capable component in this pairing.

The rank of 1222 indicates that while this is not a top-tier configuration for Doom, it delivers solid performance for a mobile CPU paired with a high-end desktop GPU. Many combos ranked above this likely feature desktop-class CPUs with higher sustained clocks, which can matter in CPU-bound scenarios at low resolutions. However, the measured FPS data shows that this combo still achieves very high frame rates at 1080p and 1440p, so the rank does not reflect a weak experience. The combo's position in the upper third of all tested combinations is respectable given the CPU's mobile nature and 28 W TDP. The data suggests that if the CPU were a more powerful desktop part, the rank could improve, but the GPU remains the primary driver of Doom's performance in most settings.

Measured FPS Breakdown

The measured FPS data provides a complete picture of how this combo performs across three resolutions and four settings presets. At 1920x1080, the average FPS ranges from 173 at Ultra to 288 at Low. The High preset delivers 212 FPS average, while Medium produces 251 FPS with a minimum of 213 and maximum of 289. These numbers indicate that at 1080p, the combo is rarely constrained by the GPU, and the CPU is capable of sustaining very high frame rates.

Moving to 2560x1440, the averages drop but remain high. Low settings produce 186 FPS, High delivers 137 FPS, and Ultra yields 112 FPS. Medium settings show an average of 162 FPS with a minimum of 138 and maximum of 187. The drop from 1080p to 1440p is roughly 35 percent for Low settings (288 to 186 FPS), which is consistent with the increased pixel count requiring more GPU work.

At 3840x2160, the performance becomes more demanding. Low settings average 101 FPS, Medium averages 88 FPS with a minimum of 75 and maximum of 101, High averages 74 FPS, and Ultra drops to 61 FPS. The 4K Ultra result is the only configuration that falls below the 60 FPS threshold, although it stays above it. The minimum FPS recorded at 4K Medium is 75, which is still smooth for a fast-paced shooter. The data shows a clear pattern: as resolution increases, the GPU becomes the limiting factor, and the difference between settings presets narrows in percentage terms.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and refresh rate. For 1080p displays, the High preset at 212 FPS average provides an excellent experience with visual quality and high frame rates. The Ultra preset at 173 FPS still offers very high performance, so players with 144Hz or 165Hz monitors can comfortably use Ultra settings at 1080p. The Medium preset at 251 FPS is only necessary for 240Hz displays where every frame counts, but the visual compromise may not be worth the extra frames.

For 1440p, the High preset at 137 FPS average is the recommended choice for most users. It clears the 120 FPS threshold and provides a good balance of visual fidelity and smoothness. The Medium preset at 162 FPS is viable for 165Hz displays, while Ultra at 112 FPS remains playable but may not fully utilize a 144Hz monitor. The Low preset at 186 FPS is excessive for most displays and sacrifices too much visual quality.

For 4K, the situation changes. The High preset at 74 FPS average is the best option for a 60Hz display, providing headroom above 60 FPS and good visual quality. The Medium preset at 88 FPS is a strong alternative if higher frame rates are desired, though the minimum of 75 FPS indicates some frame time variance. The Ultra preset at 61 FPS is technically playable but leaves no headroom for demanding scenes, potentially causing dips below 60 FPS. The Low preset at 101 FPS is unnecessary at 4K since the visual degradation is significant and the frame rate gain is not needed for most displays. For the best overall experience, the High preset at 1440p or 4K offers the strongest balance of visual quality and performance.

Resolution Scaling

The FPS data reveals a consistent scaling pattern as resolution increases from 1080p to 4K. At Low settings, the average FPS drops from 288 at 1080p to 186 at 1440p, a 35 percent reduction, and then to 101 at 4K, a 46 percent reduction from 1440p. The scaling is roughly proportional to the pixel count increase: 1080p has 2.07 million pixels, 1440p has 3.69 million, and 4K has 8.29 million. The fact that FPS does not drop proportionally to pixel count indicates that the GPU is not purely pixel-bound at every resolution.

At High settings, the pattern is similar but with lower absolute numbers: 212 FPS at 1080p, 137 FPS at 1440p (35 percent drop), and 74 FPS at 4K (46 percent drop). The consistent percentage drops across settings suggest that the GPU's compute and memory bandwidth are scaling predictably with resolution. The RTX 4080's 716.8 GB/s memory bandwidth appears sufficient to feed the GPU at 4K, as the FPS drops are not steeper than expected.

The limiting component shifts with resolution. At 1080p, the CPU's 16 cores and 22 threads are more likely to be a bottleneck, as evidenced by the very high FPS figures that approach the CPU's ability to issue draw calls. At 4K, the GPU's 9728 shading units are clearly the primary constraint, particularly at Ultra settings where 61 FPS average indicates the GPU is saturated. The data shows that this combo is well-balanced: the CPU can push high frame rates at lower resolutions, while the GPU provides strong performance at higher resolutions. The 4K Ultra result of 61 FPS, while not a high refresh rate experience, demonstrates that the RTX 4080 can handle demanding scenarios in Doom, and the CPU does not drag down performance at any resolution tested.
