Doom

The Intel Core Ultra 7 155H paired with the AMD Radeon 760M produces a strictly entry-level experience in Doom, with the measured frame rates placing this combo in the 2919th position out of 2930 tested combinations. The data indicates this system is at the very bottom of the performance pile, and the benchmark results consistently reinforce that conclusion across every resolution and settings preset.

Settings Recommendations

The measured FPS data points to a single viable path for playable performance: the Low preset at 1920x1080. At this setting, the combo achieves an average of 65 FPS, which is the only configuration in the entire dataset to cross the 60 FPS threshold. The Medium preset at the same resolution drops to 57 FPS average, which is still technically playable but leaves less headroom for demanding scenes. The Low preset at 1920x1080 is the clear recommendation for any user who prioritizes smooth motion over visual fidelity.

For those who insist on higher image quality, the High preset at 1920x1080 yields 48 FPS average, while Ultra falls to 39 FPS. Neither of these settings provides the consistency needed for a fast-paced FPS, and the data suggests that sacrificing visual detail is the only way to approach a fluid experience. At 2560x1440, even the Low preset only manages 42 FPS, which falls below the playability threshold for most users. The 3840x2160 resolution is effectively unusable, with even the Low preset producing just 23 FPS.

The benchmark results indicate that the best experience is achieved by locking to 1920x1080 and accepting the Low preset. The Medium preset at 1080p offers a marginal improvement in visuals for a 12% reduction in average frame rate, but the Low preset's 65 FPS provides the stability required for responsive gameplay. Pushing beyond Medium settings at any resolution results in average frame rates that drop below 50 FPS, which is a significant compromise for a game that demands quick reactions.

GPU Role

The AMD Radeon 760M is the primary bottleneck in this configuration, and its specifications explain the consistently low frame rates. The integrated graphics solution features 512 shading units, 32 texture mapping units, and 16 raster output pipelines, with a base clock of 800 MHz and a boost clock of 2599 MHz. The GPU's memory configuration is entirely system-dependent, using shared memory with a bus width and bandwidth that scale with the host system's DDR5 memory.

The GPU's compute capabilities are modest, with a peak FP32 throughput of 5.323 TFLOPS and a pixel rate of 41.58 GPixel/s. The texture rate of 83.17 GTexel/s further illustrates the limited fill rate available for rendering scenes. The Radeon 760M sits at the 35th percentile of all GPUs in the benchmark database, with an average benchmark score of 6019. Its nearest rivals include the AMD Radeon RX 6400 with a score of 6001 and the NVIDIA GeForce GTX 770M at 6000, both within 0.3% of the 760M's score.

The GPU's DirectX 12 Ultimate support and Vulkan 1.4 compatibility are modern, but the raw processing power is insufficient for demanding workloads. The integrated nature of the GPU, with a 15 W TDP and no dedicated power connectors, means it shares thermal and power resources with the CPU. This shared architecture is reflected in the frame rates, where even the lowest settings at 1080p cannot exceed 65 FPS. The data suggests that the GPU's 16 ROPs are particularly limiting, as the resolution scaling shows a steep performance drop when pixel count increases.

CPU Role

The Intel Core Ultra 7 155H provides ample processing power that is largely underutilized in this GPU-bound scenario. The CPU features 16 cores and 22 threads, with a base clock of 3.80 GHz and a boost clock of 4.80 GHz. This Meteor Lake architecture processor includes a 24 MB shared L3 cache, with 112 KB per core of L1 cache and 2 MB per core of L2 cache. The CPU's memory bandwidth is rated at 89.6 GB/s over a dual-channel DDR5 interface.

The CPU's benchmark results demonstrate strong multi-threaded performance, with a Cinebench R23 multi-core score of 15028 and a single-core score of 1743. The Passmark multi-thread score of 24873 and single-thread score of 3468 further confirm the processor's capabilities. The CPU sits at the 83rd percentile of all CPUs, with an average benchmark score of 32697. Its nearest rivals include the Intel Core i5-14600T at 32707 and the AMD Ryzen AI 7 PRO 360 at 32662, both essentially matching the 155H's performance.

In the context of Doom, the CPU's 16 cores and 22 threads are far more than the game requires, as the frame rates are consistently limited by the GPU. The CPU's integrated Arc Xe-LPG 128EU graphics are not the primary renderer in this configuration, but the shared power budget between CPU and GPU means that the CPU's 28 W TDP constrains the GPU's ability to sustain boost clocks. The CPU's high single-thread performance is irrelevant when the GPU cannot keep up, as the frame rate data shows no variation that would suggest CPU limitation.

How This Combo Ranks

This CPU-GPU combination ranks 2919 out of 2930 tested combos in Doom, placing it in the bottom 0.4% of all configurations. This ranking is consistent with the individual component percentiles, where the CPU ranks at the 83rd percentile but the GPU languishes at the 35th percentile. The GPU's low standing drags the entire combo down, as the CPU's strong performance cannot compensate for the integrated graphics' limitations.

The benchmark data indicates that this combo is nearly the worst possible configuration for Doom, with only 11 other combinations performing worse. The gap between this combo and the median configuration is substantial, as the frame rates at 1080p Low (65 FPS) are roughly half of what a mid-range discrete GPU would achieve. The combo's ranking is particularly telling when considering that the CPU is in the top 20% of all processors, yet the overall system performance is in the bottom 1%.

The nearest rival comparisons for the GPU show that the Radeon 760M is on par with entry-level discrete GPUs like the RX 6400, but these comparisons are based on synthetic benchmarks. In real-world gaming, the integrated GPU's shared memory architecture and power constraints likely cause it to fall behind even these modest discrete solutions. The data suggests that this combo is only suitable for the most undemanding gaming scenarios, and Doom at 1080p Low represents the upper limit of what this system can handle.

Resolution Scaling

The frame rate progression from 1920x1080 to 3840x2160 reveals a clear pattern of GPU limitation. At Low settings, the average FPS drops from 65 at 1080p to 42 at 1440p and 23 at 4K, representing a 35% reduction from 1080p to 1440p and a 45% reduction from 1440p to 4K. This scaling is consistent with a GPU that is overwhelmed by increasing pixel counts, as the number of pixels quadruples from 1080p to 4K but the frame rate only drops by roughly two-thirds.

The Medium preset shows a similar trend, with 57 FPS at 1080p, 37 FPS at 1440p, and 20 FPS at 4K. The High preset follows the same pattern: 48 FPS at 1080p, 31 FPS at 1440p, and 17 FPS at 4K. The Ultra preset is the most demanding, with 39 FPS at 1080p, 25 FPS at 1440p, and 14 FPS at 4K. Across all settings, the drop from 1080p to 1440p is consistently around 35-38%, while the drop from 1440p to 4K is consistently around 42-45%.

This resolution scaling behavior strongly indicates that the GPU is the limiting component. The CPU's performance is constant regardless of resolution, so if the CPU were the bottleneck, we would expect similar frame rates across resolutions. Instead, the frame rates scale inversely with pixel count, which is the hallmark of a GPU-bound scenario. The 4K results are particularly telling, with even the Low preset producing just 23 FPS, which is barely above a slideshow.

Measured FPS Breakdown

At 1920x1080, the Low preset delivers an average of 65 FPS, which is the highest score in the entire dataset. The Medium preset at this resolution produces 57 FPS average, with a minimum of 48 FPS and a maximum of 66 FPS. The High preset drops to 48 FPS average, while the Ultra preset manages only 39 FPS. These results show a clear progression where each settings tier costs roughly 8-9 FPS on average.

Moving to 2560x1440, the Low preset achieves 42 FPS average, followed by Medium at 37 FPS (minimum 31, maximum 42), High at 31 FPS, and Ultra at 25 FPS. The gap between Low and Ultra at 1440p is 17 FPS, which is a wider spread than at 1080p, indicating that the GPU's limitations become more pronounced at higher resolutions. The Medium preset's minimum of 31 FPS suggests that frame pacing may be inconsistent, with occasional dips below the average.

At 3840x2160, the Low preset produces 23 FPS average, Medium drops to 20 FPS (minimum 17, maximum 23), High reaches 17 FPS, and Ultra falls to 14 FPS. The 4K results are uniformly poor, with even the best case (Low) failing to reach 24 FPS, which is the standard for basic video playback. The Medium preset at 4K has a minimum of 17 FPS, indicating that the GPU can experience even more severe dips during intense scenes.
