Doom

The Intel Core Ultra 7 155H paired with the AMD Radeon 8050S delivers a highly playable Doom experience across most settings, with the data showing a clear shift in bottleneck behavior as resolution increases. At 1080p, the system produces frame rates well above typical display refresh rates, while at 4K, the frame rate drops into a range that requires settings adjustments for consistent smoothness. This combination ranks 2146th out of 2930 tested combos for this title, placing it in the lower-middle portion of the database, yet the measured results indicate that the hardware is well-matched for the game’s engine.

Resolution Scaling

The measured FPS data reveals a predictable and steep decline as resolution scales from 1920x1080 to 3840x2160. At High settings, the average frame rate falls from 139 FPS at 1080p to 90 FPS at 1440p, and finally to 49 FPS at 4K. This represents a 65% drop from 1080p to 4K, indicating that the rendering load at 4K is substantially heavier. The transition from 1080p to 1440p costs 49 FPS, while the move from 1440p to 4K costs another 41 FPS, suggesting that the scaling is not perfectly linear but rather steepens at higher resolutions.

The pattern across all settings confirms that the GPU becomes the limiting factor at 4K. At Ultra settings, the frame rate drops to 40 FPS at 4K, which is a 65% reduction from the 113 FPS seen at 1080p. At Low settings, the 4K result of 66 FPS is 65% lower than the 188 FPS at 1080p. This consistent percentage drop across all quality presets strongly implies that the AMD Radeon 8050S’s compute and memory bandwidth are the primary constraints at 3840x2160, rather than the CPU.

The scaling from 1080p to 1440p shows a more moderate reduction, with the average FPS dropping by roughly 35% across all settings. This indicates that while the GPU is still heavily loaded, the system has enough headroom to maintain playable rates. The data suggests that 1440p is the sweet spot for this combination, as the frame rates remain well above 60 FPS even at High settings, whereas 4K requires dropping to Medium or Low to achieve similar fluidity.

CPU Role

The Intel Core Ultra 7 155H features 16 cores and 22 threads, with a base clock of 3.80 GHz and a boost clock of 4.80 GHz. This mobile processor is built on Intel’s 7 nm Meteor Lake architecture and is designed for high-end laptops. Its benchmark scores place it in the 83rd percentile of all CPUs, with an average benchmark score of 32697. Compared to its nearest rivals, it performs nearly identically to the Intel Core i5-14600T (deltaPct 0) and the AMD Ryzen AI 7 PRO 360 (deltaPct 0.1), while slightly outperforming the AMD Ryzen 5 7400F (deltaPct -0.2) and the AMD Ryzen 7 PRO 6850H (deltaPct -0.4).

In Doom, the CPU’s role is most apparent at lower resolutions where the GPU is not saturated. At 1080p Low settings, the system achieves 188 FPS, which is the highest measured frame rate in the dataset. This indicates that the processor can feed the GPU with enough draw calls and physics calculations to sustain very high frame rates. The single-thread performance, as evidenced by a Cinebench R23 single-core score of 1743, is sufficient for the game’s main thread, while the multi-core score of 15028 ensures that background tasks and additional game threads do not cause stutters.

The 24 MB of shared L3 cache helps maintain low latency access to frequently used game data, which is critical for maintaining consistent frame pacing in a fast-paced FPS. The data shows that at 4K, the CPU is not the bottleneck, as the frame rates drop uniformly with resolution regardless of the quality preset. This suggests that the 155H’s 22 threads provide ample headroom for the game’s AI and scripting logic, even when the GPU is struggling to render at 2160p.

GPU Role

The AMD Radeon 8050S is an integrated GPU based on the RDNA 3.5 architecture, manufactured on TSMC’s 4 nm process. It features 2048 shading units, 128 texture mapping units, and 64 raster operation units, along with 32 ray tracing cores. The GPU has a base clock of 1295 MHz and a boost clock of 2800 MHz, offering a peak FP32 performance of 11.47 TFLOPS. Its memory is system-shared, meaning it relies on the host’s DDR5 memory, with bandwidth dependent on the system configuration.

The GPU’s benchmark results place it in the 89th percentile of all GPUs, with an average score of 62108. Its nearest rival is the AMD Radeon Pro W6600M, which scores 61896, a 0.3% difference. The Radeon 8050S outperforms the AMD Radeon Pro Vega 56 by 2.5% and the AMD Radeon RX 7600M by 2.6%, showing that it is a competitive mobile graphics solution.

In Doom, the GPU’s performance is the defining factor at 4K resolutions. At 4K Ultra, the average FPS is 40, which is marginally playable but not smooth. Dropping to 4K High increases the average to 49 FPS, while 4K Medium reaches 57 FPS and 4K Low achieves 66 FPS. This scaling shows that the GPU’s 2048 shaders are pushed to their limit at 2160p, and the system-shared memory bandwidth becomes a constraint. The pixel rate of 179.2 GPixel/s and texture rate of 358.4 GTexel/s are insufficient to maintain high frame rates at 4K with demanding settings.

Measured FPS Breakdown

At 1920x1080, the system delivers excellent performance across all settings. Low settings produce an average of 188 FPS, Medium achieves 164 FPS, High reaches 139 FPS, and Ultra yields 113 FPS. These results indicate that the CPU and GPU combination is well-balanced at this resolution, with no single component severely limiting performance. The difference between Low and Ultra is 75 FPS, showing that the quality presets have a significant impact on the GPU workload.

Moving to 2560x1440, the frame rates remain strong but show the expected decline. Low settings average 122 FPS, Medium averages 106 FPS, High averages 90 FPS, and Ultra averages 73 FPS. The gap between Low and Ultra narrows to 49 FPS, indicating that the GPU is becoming more of a limiting factor. The Medium preset at 1440p has a minimum FPS of 90 and a maximum of 122, providing a smooth experience for most players.

At 3840x2160, the performance drops significantly. Low settings average 66 FPS, Medium averages 57 FPS with a minimum of 49 and maximum of 66, High averages 49 FPS, and Ultra averages 40 FPS. The data shows that 4K gaming requires careful settings management, as only the Low preset maintains an average above 60 FPS. The Ultra preset at 4K is likely to feel sluggish, with an average of 40 FPS that may dip lower during intense scenes.

How This Combo Ranks

The Intel Core Ultra 7 155H and AMD Radeon 8050S combination ranks 2146th out of 2930 tested combos for Doom. This places it in the 27th percentile of all tested systems, meaning that approximately 73% of combos in the database deliver higher frame rates in this game. This ranking is consistent with the hardware’s positioning as a mid-range mobile solution, where the integrated GPU’s performance is the primary constraint.

The CPU’s 83rd percentile ranking among all CPUs contrasts sharply with the combo’s overall rank, confirming that the processor is not the limiting factor. The GPU’s 89th percentile ranking among all GPUs is also higher than the combo’s overall game-specific rank, suggesting that Doom’s rendering requirements are particularly demanding on this integrated solution. The 784-combo gap between this system and the top performers is primarily due to the GPU’s inability to sustain high frame rates at 4K, as the 1080p results are competitive with many discrete GPU laptops.

When compared to the nearest rival GPUs, the Radeon 8050S’s 2.6% advantage over the RX 7600M and 2.5% advantage over the Pro Vega 56 do not translate into a significantly better Doom experience, as the game’s engine scales rapidly with raw compute and memory bandwidth. The combo rank reflects that while this system is capable of playing Doom, it does so at lower settings and resolutions than more powerful configurations.

Settings Recommendations

For players targeting 60 FPS as a baseline, the data supports specific settings choices based on resolution. At 1920x1080, all presets exceed 60 FPS, with even Ultra averaging 113 FPS. The Medium preset at 164 FPS offers a balanced experience with a minimum of 139 FPS, making it the recommended choice for high refresh rate displays. The High preset at 139 FPS is also excellent, providing better visual quality while still maintaining triple-digit frame rates.

At 2560x1440, the Ultra preset averages 73 FPS, which is above 60 FPS but may experience occasional dips. The High preset at 90 FPS is the safest recommendation for a smooth 1440p experience, as it provides a significant margin above the 60 FPS threshold. The Medium preset at 106 FPS is ideal for players who prefer higher frame rates and are willing to compromise on visual fidelity.

At 3840x2160, only the Low preset averages above 60 FPS at 66 FPS. The Medium preset averages 57 FPS with a minimum of 49, which may be acceptable for slower-paced gameplay but is not ideal for a fast FPS. The High preset at 49 FPS and Ultra at 40 FPS are not recommended for competitive play. For 4K, the Low preset is the only setting that ensures a consistently playable frame rate, while Medium can be used if the player accepts the risk of drops below 50 FPS.
