Doom

The Intel Core Ultra X9 388H paired with the AMD Radeon 880M is a combination that ranks near the bottom of the database for Doom, placing 2858th out of 2930 tested combos. This position reflects a system that is fundamentally constrained by its integrated graphics, though the CPU's strong showing in synthetic benchmarks suggests the processor is not the primary bottleneck in this title. The measured frame rates confirm that this combo is only viable at lower resolutions and settings, with performance degrading sharply as graphical demands increase.

How This Combo Ranks

The combo's rank of 2858 out of 2930 places it in the bottom 2.5% of all tested configurations for Doom. This is a decisive indicator that the system is not built for high-refresh-rate or high-fidelity gaming in this title. The data shows a clear pattern: the AMD Radeon 880M, an integrated graphics solution, is the limiting factor, and the scores reflect the hardware's position in the broader market.

The processor itself, the Intel Core Ultra X9 388H, performs admirably in synthetic tests, with an average benchmark score of 44466 and a percentile rank of 88 against all CPUs. However, this raw CPU strength does not translate to playable frame rates in Doom at higher settings. The nearest CPU rivals—the AMD Ryzen 5 7500X3D, Intel Core i9-13950HX, AMD Ryzen AI Max 385, and Intel Core i5-13600—all post average scores within 0.5% of the Ultra X9 388H, indicating that the processor's compute capabilities are competitive with those mid-to-high-end parts. Yet, the GPU's percentile rank of just 43 against all GPUs tells the real story for gaming.

The measured FPS data reinforces this ranking. At 4K Ultra, the combo manages only 19 FPS, which is far below the threshold for playable performance. Even at 1080p Low, the best-case scenario, the system reaches 90 FPS, which is acceptable but not exceptional. The overall rank suggests that while the CPU is a capable component, the integrated GPU holds the entire system back in a fast-paced FPS like Doom, where smoothness and responsiveness are critical.

GPU Role

The AMD Radeon 880M is an integrated graphics processor based on the RDNA 3.5 architecture, built on a 4 nm process at TSMC. It features 768 shading units, 48 texture mapping units, and 16 raster operation pipelines, along with 12 ray tracing cores. The GPU operates at a base clock of 400 MHz and can boost up to 2900 MHz, which provides a theoretical FP32 performance of 4.454 TFLOPS. Its memory configuration is entirely system-shared, meaning it relies on the host system's LPDDR5X memory, with bandwidth that is system-dependent rather than dedicated.

In Doom, the GPU's role is decisive. The data shows that the Radeon 880M's performance is the primary constraint on frame rates. At 1080p Low, the combo achieves 90 FPS, but this drops to 54 FPS at 1080p Ultra, a 40% reduction. The pattern continues at higher resolutions: at 1440p, the average FPS ranges from 58 at Low to 35 at Ultra, and at 4K, the range falls to 31 at Low and 19 at Ultra. These numbers illustrate that the GPU's fill rate and compute capabilities are insufficient for the demands of higher resolutions and quality presets.

The GPU's nearest rivals in the database—the NVIDIA GeForce GTX 675MX, NVIDIA GeForce MX330, AMD Radeon HD 8870M, and AMD Radeon R9 M375X—all have average scores within 1.3% of the Radeon 880M. This places it in the same performance tier as older discrete mobile GPUs from a decade ago, which is telling for a modern integrated solution. The pixel rate of 46.40 GPixel/s and texture rate of 139.2 GTexel/s are modest figures that explain the difficulty in maintaining high frame rates at 4K, where the GPU must process over 8 million pixels per frame.

Settings Recommendations

Based on the measured FPS data, the optimal experience for this combo in Doom is at 1080p with Low settings, where the average frame rate is 90 FPS. This is the only configuration that consistently approaches the high-refresh-rate territory that benefits an FPS title. At 1080p Medium, the average drops to 78 FPS, which is still playable, but the jump to High brings it down to 66 FPS, and Ultra falls to 54 FPS. For players prioritizing smoothness over visual fidelity, Low settings at 1080p is the clear recommendation.

At 1440p, the situation becomes more challenging. The Low preset yields 58 FPS, which is borderline for a competitive shooter, while Medium drops to 51 FPS and High to 43 FPS. The Ultra preset at 1440p is not recommended, as it averages just 35 FPS, which is likely to feel stuttery in fast-paced gameplay. The data suggests that 1440p is only viable if players are willing to accept lower visual quality and a frame rate that hovers around the 50-60 FPS range.

At 4K, none of the settings provide a playable experience. The Low preset averages 31 FPS, Medium 27 FPS, High 23 FPS, and Ultra 19 FPS. These numbers are well below the minimum threshold for smooth gameplay in a first-person shooter. The recommendation is to avoid 4K entirely with this combo, as even the lowest settings cannot push the frame rate into an acceptable range. The measured minimum FPS values at Medium settings (31 FPS at 4K, 43 FPS at 1440p, and 66 FPS at 1080p) also indicate potential stuttering during intense scenes, further supporting the case for 1080p Low.

Measured FPS Breakdown

The measured frame rates provide a detailed picture of the combo's performance across resolutions and settings. At 1920x1080, the lowest resolution tested, the system delivers an average of 90 FPS on Low settings, 78 FPS on Medium, 66 FPS on High, and 54 FPS on Ultra. The Medium preset shows a minimum FPS of 66 and a maximum of 90, indicating that frame times are relatively consistent at this resolution. The step from Low to Ultra represents a 40% reduction in performance, which is significant but not as severe as at higher resolutions.

Moving to 2560x1440, the average frame rates drop to 58 FPS on Low, 51 FPS on Medium, 43 FPS on High, and 35 FPS on Ultra. The Medium preset at this resolution has a minimum of 43 FPS and a maximum of 58, showing a wider variance than at 1080p. The performance loss from 1080p to 1440p is roughly 35-36% across all settings, which is a substantial hit that underscores the GPU's limitations.

At 3840x2160, the performance falls off a cliff. The average frame rates are 31 FPS on Low, 27 FPS on Medium, 23 FPS on High, and 19 FPS on Ultra. The Medium preset shows a minimum of 23 FPS and a maximum of 31 FPS, which is unplayable for a fast-paced game like Doom. The transition from 1440p to 4K results in a performance drop of approximately 46-47%, indicating that the GPU is severely overburdened at this resolution. The data clearly shows that 4K is not a viable option for this combo.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals that the AMD Radeon 880M is the dominant bottleneck. When moving from 1920x1080 to 2560x1440, the average frame rates drop by roughly 35% across all settings. For example, at Low settings, the FPS falls from 90 to 58, a 35.6% reduction. At Ultra settings, the drop is from 54 to 35, a 35.2% reduction. This consistent scaling indicates that the GPU is the limiting factor, as the workload increases linearly with pixel count.

The transition from 1440p to 4K shows an even more severe drop of approximately 46-47%. At Low settings, the FPS falls from 58 to 31, a 46.6% reduction, while at Ultra, it drops from 35 to 19, a 45.7% reduction. This steeper decline at higher resolutions suggests that the GPU is running out of memory bandwidth and compute resources, as the 4K resolution requires processing four times the pixels of 1080p. The system-shared memory architecture of the Radeon 880M likely exacerbates this issue, as the GPU and CPU compete for the same memory bandwidth.

The scaling pattern is a clear indicator that the CPU is not a limiting factor in this game. The Intel Core Ultra X9 388H, with its 16 cores and 16 threads, has more than enough processing power to handle the game logic and draw calls at these frame rates. The data shows that the FPS drops are almost entirely attributable to the GPU's inability to keep up with the increasing pixel load. This is consistent with the combo's low rank, as the integrated GPU simply does not have the raw throughput needed for higher-resolution gaming.

CPU Role

The Intel Core Ultra X9 388H is a 16-core, 16-thread processor based on the Panther Lake architecture, built on Intel's 3 nm process. It has a base clock of 2.10 GHz and a boost clock of 5.10 GHz, with a TDP of 25 W. The CPU features a substantial cache hierarchy, including 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 18 MB of shared L3 cache. Memory support includes dual-channel LPDDR5X with a bandwidth of 153.6 GB/s.

In Doom, the CPU's role is supportive rather than primary. The synthetic benchmarks show that the processor is highly capable, with a Cinebench R23 multi-core score of 18911 and a single-core score of 2200.5. The PassMark multi-thread score of 36811 and single-thread score of 4280 place it in the top tier of mobile processors. However, the game's frame rates are not limited by the CPU, as evidenced by the consistent FPS drops when increasing resolution or settings.

The CPU's nearest rivals—the AMD Ryzen 5 7500X3D, Intel Core i9-13950HX, AMD Ryzen AI Max 385, and Intel Core i5-13600—all have average scores within 0.5% of the Ultra X9 388H. This indicates that the processor is competitive with these parts in general compute tasks. Yet, the measured FPS in Doom is far below what these CPUs could achieve with a dedicated GPU, reinforcing that the integrated Radeon 880M is the bottleneck. The CPU's high boost clock of 5.10 GHz ensures that single-threaded performance is strong, which is important for game logic, but it cannot compensate for the GPU's limitations.

The data suggests that the CPU is not the limiting component in this combo for Doom. The FPS scaling from 1080p to 4K follows the GPU's expected performance curve, and the CPU's synthetic scores are far above what would be needed to drive the observed frame rates. For players considering this combo, the CPU is a solid foundation, but the integrated GPU will prevent the system from reaching high frame rates or high resolutions in demanding titles like Doom. The 16 cores and 16 threads provide ample parallelism for modern games, but the lack of a discrete GPU means that the system's gaming performance is capped by the Radeon 880M's capabilities.
