Doom

Doom’s 2016 engine is known for its scalability, and the measured data for this Intel Core Ultra 7 155H + NVIDIA GeForce RTX 5070 combination confirms that trait. The dataset shows a clear, predictable progression of frame rates as resolution increases, with the most significant performance penalty occurring between 1440p and 4K. At 1080p, the system delivers triple-digit averages across all settings, suggesting the CPU and GPU have ample headroom. Moving to 2560x1440, the averages remain high, but the scaling from 1080p indicates the graphics card is beginning to assert its influence. The jump to 3840x2160 is where the most dramatic drop occurs, with the Ultra preset falling below 50 FPS. This pattern is classic GPU-bound behavior; the RTX 5070 is the primary limiter at higher resolutions.

Resolution Scaling

The frame rate scaling across resolutions provides a clear picture of where the bottleneck lies. From 1920x1080 to 2560x1440, the performance drop is noticeable but manageable; for instance, the High preset falls from 165 FPS to 107 FPS, a reduction of 58 FPS. However, the scaling from 1440p to 4K is far more punishing. The same High preset drops from 107 FPS to 58 FPS, halving the frame rate. This steep decline indicates that the GPU’s rendering load is growing faster than its capabilities at that resolution.

This pattern is consistent across all settings. The Low preset at 1080p hits 224 FPS, which is likely far beyond the refresh rate of most displays. At 1440p, the Low preset still manages 145 FPS, but at 4K, it falls to 79 FPS. The Medium preset follows a similar trajectory: 195 FPS at 1080p, 126 FPS at 1440p, and 68 FPS at 4K. The Ultra preset is the most demanding, starting at 135 FPS at 1080p, dropping to 87 FPS at 1440p, and culminating in a 47 FPS average at 4K. The data shows that the 4K resolution is the threshold where this combination begins to struggle, particularly with higher graphical settings.

The limiter is clearly the GPU. The CPU’s performance, as measured by its benchmark scores, is sufficient to feed the GPU at lower resolutions, but the sheer pixel count at 4K overwhelms the RTX 5070. The fact that the difference between Low and Ultra at 1080p is 89 FPS (224 vs 135) suggests the GPU is still the primary driver of performance even at lower resolutions, though the CPU is keeping up. In contrast, at 4K, the difference between Low and Ultra is only 32 FPS (79 vs 47), indicating that the GPU is so saturated that even reducing settings cannot fully compensate for the resolution penalty.

How This Combo Ranks

In the grand scheme of tested combinations, this pairing of the Intel Core Ultra 7 155H and the NVIDIA GeForce RTX 5070 holds a specific position. The `comboRankInGame` field places this setup at rank 2056 out of 3712 possible combinations. This percentile places it in the upper-middle tier of all tested systems for Doom. While it is not a top-tier performer, it is far from a low-end configuration. The rank suggests that a significant number of other CPU-GPU pairings can outperform it, but it also outperforms a majority of the tested combos.

The ranking is a holistic measure, blending the capabilities of both the CPU and GPU. The RTX 5070’s individual percentile is 82, meaning it is better than 82% of all GPUs in the database. The CPU’s percentile is 83, showing a similar level of standing. When combined, their performance in Doom is slightly below what their individual percentiles might suggest, indicating that the game’s workload may not perfectly scale with raw benchmark scores. The nearest rivals for the GPU, such as the AMD Radeon Pro 580 and the AMD Radeon Pro WX 7100, have very similar average scores, with deltas of 0.1% and 0.8% respectively, showing that the GPU is in a tightly contested performance band.

For the CPU, the nearest rivals are the Intel Core i5-14600T, the AMD Ryzen AI 7 PRO 360, the AMD Ryzen 5 7400F, and the AMD Ryzen 7 PRO 6850H. The deltas among these are minimal, ranging from 0.1% to -0.4%, suggesting the CPU’s performance is also highly competitive with its direct competitors. The combo’s rank of 2056, therefore, is a function of the game’s specific optimization for these components, not a reflection of weak individual parts. For a game like Doom, which favors high frame rates, this rank indicates a system that is capable of smooth gameplay at 1080p and 1440p, but requires compromises at 4K.

GPU Role

The NVIDIA GeForce RTX 5070 is the dominant component in this pairing for Doom. Its specifications are robust, featuring 12 GB of GDDR7 memory on a 192-bit bus, delivering a bandwidth of 672.0 GB/s. The memory clock is listed at 1750 MHz, with an effective rate of 28 Gbps. The GPU’s base clock is 2325 MHz, with a boost clock of 2512 MHz. These clocks are crucial; the boost clock is what the GPU sustains under load, and the data suggests it is being fully utilized at higher resolutions.

The GPU’s memory capacity of 12 GB is a key factor. Doom is not a particularly VRAM-hungry title, but at 4K with Ultra settings, the memory usage can become significant. The data shows that the Ultra preset at 4K produces a 47 FPS average, which is below the 60 FPS target. This is likely due to the GPU’s compute limitations rather than a lack of VRAM, as the Low and Medium presets at 4K still achieve 79 FPS and 68 FPS respectively, indicating that the graphics card can handle the resolution when the texture quality is reduced. The GPU’s architecture, Blackwell 2.0, is built on a 5 nm process, which contributes to its efficiency, but its raw power is the deciding factor here.

The GPU’s benchmark scores in the pack are mixed. Its 3DMark Steel Nomad DX12 score is 5077, and its Geekbench Vulkan score is 178923. These scores are indicative of a high-performance part. However, in Doom, the performance at 4K is constrained. The RTX 5070’s nearest rivals in the database include the AMD Radeon Pro 580 and the NVIDIA RTX A500 Mobile, with score deltas of 0.1% and 2% respectively. This shows that while the RTX 5070 is a capable card, it is not leaps and bounds ahead of its nearest competitors in synthetic benchmarks, which translates to a competitive but not dominant position in actual gameplay. The 30.87 TFLOPS FP32 performance is substantial, but it is not enough to brute-force 4K Ultra in Doom.

Measured FPS Breakdown

The measured FPS data provides a detailed look at the system’s capabilities. At 1920x1080, the system is exceptionally fast. The Low preset achieves an average of 224 FPS, with the Medium preset at 195 FPS and the High preset at 165 FPS. The Ultra preset still manages a very playable 135 FPS. The Medium preset shows a minimum FPS of 166 and a maximum of 224, indicating that the frame times are consistent and there are no major hitches. This resolution is ideal for high-refresh-rate monitors, as even the Ultra settings will outpace a 144Hz display.

Moving to 2560x1440, the performance remains strong but begins to show the GPU’s workload. The Low preset averages 145 FPS, which is still excellent. The Medium preset averages 126 FPS, with a minimum of 107 and a maximum of 145. The High preset comes in at 107 FPS, which is right at the threshold for a 100Hz+ display. The Ultra preset drops to 87 FPS, which is still playable but requires a variable refresh rate (VRR) monitor to feel smooth during intense scenes. The transition from 1080p to 1440p shows a consistent drop of roughly 40-50 FPS across all settings, which is a significant but expected cost for the increase in pixel density.

At 3840x2160, the system’s limitations are clear. The Low preset is the only one that maintains a comfortable frame rate, with an average of 79 FPS. The Medium preset averages 68 FPS, with a minimum of 58 and a maximum of 79. The High preset drops to 58 FPS, which is just at the edge of playability. The Ultra preset is the worst performer, with an average of 47 FPS. This is below the 60 FPS standard, and for a fast-paced FPS like Doom, it will be noticeably less smooth. The data shows that for a consistent 60 FPS experience at 4K, the user would need to stick to the Medium preset or lower. The High preset is borderline, and Ultra is not recommended for competitive play.

CPU Role

The Intel Core Ultra 7 155H plays a supporting role in this configuration, but it is not a bottleneck. The CPU features 16 cores and 22 threads, with a base clock of 3.80 GHz and a boost clock of 4.80 GHz. Its architecture is Meteor Lake, built on a 7 nm process. The CPU’s benchmark scores are strong; for instance, its Cinebench R23 multi-core score is 15028, and its single-core score is 1743. The Passmark multi-thread score is 24873, and the single-thread score is 3468. These numbers indicate a very capable processor for gaming.

In Doom, the CPU’s role is to feed the GPU with draw calls and game logic. The data suggests that at 1080p, the CPU is not the limiting factor; the GPU is. The fact that the Low preset at 1080p hits 224 FPS shows that the CPU can keep up with high frame rates. If the CPU were a bottleneck, we would see frame rates plateau regardless of the resolution or settings. This is not the case; the frame rates scale with the resolution, which is the classic sign of a GPU-limited scenario.

The CPU’s performance is also competitive with its nearest rivals. The Intel Core i5-14600T, the AMD Ryzen AI 7 PRO 360, and the AMD Ryzen 5 7400F all have average scores within 0.2% of the Core Ultra 7 155H. This means that swapping the CPU for one of these alternatives would likely yield very similar results in Doom. The CPU’s high single-thread performance (3468 in Passmark) is particularly important for Doom, which is a game that benefits from strong single-core performance. The 24 MB of shared L3 cache also helps with game asset loading. Overall, the CPU provides a solid foundation that allows the RTX 5070 to perform to its full potential.

Settings Recommendations

For the best experience, the data points to specific settings for each resolution. At 1920x1080, the system has so much headroom that the Ultra preset is the clear choice. With an average of 135 FPS, it provides the highest visual fidelity while still maintaining a frame rate that exceeds the refresh rate of most standard monitors. There is no practical reason to lower settings at this resolution, as even the most demanding preset is highly playable.

At 2560x1440, the Ultra preset drops to 87 FPS, which is still smooth. However, for users with a 144Hz monitor who want to maximize frame rates, the High preset at 107 FPS is a better option. It offers a significant frame rate boost (20 FPS) over Ultra, and the visual difference between High and Ultra in Doom is often subtle. The Medium preset at 126 FPS is also a good choice for competitive play, but High strikes the best balance between image quality and performance.

At 3840x2160, the choices are more constrained. The Ultra preset at 47 FPS is not recommended, as it falls below the 60 FPS threshold and the frame pacing will suffer. The High preset at 58 FPS is also borderline and may feel inconsistent. The Medium preset, with an average of 68 FPS and a minimum of 58 FPS, is the best option for a playable 4K experience. It provides a stable frame rate that is close to 60 FPS, and the visual downgrade from High to Medium is acceptable at that resolution. The Low preset at 79 FPS is the fallback if maximum fluidity is required, but it diminishes the visual fidelity that makes 4K worthwhile. In summary, the recommended presets are Ultra at 1080p, High at 1440p, and Medium at 4K.
