Doom

The Intel Core Ultra X7 368H paired with the AMD Radeon 880M delivers a playable but constrained experience in Doom, ranking near the bottom of the database’s tested combinations. With a combo rank of 2858 out of 2930, this pairing sits in the 2.5th percentile of all tested system configurations for this title, indicating that the integrated GPU is the primary bottleneck across all resolutions and settings. The data shows a system that can handle the game at 1080p with adjusted expectations, but struggles significantly as resolution increases.

How This Combo Ranks

The combination of the Intel Core Ultra X7 368H and AMD Radeon 880M ranks 2858th out of 2930 tested combos in Doom, placing it in the bottom 2.5% of all configurations. This is a remarkably low standing that reflects the fundamental limitation of relying on an integrated GPU for a fast-paced FPS title. The CPU itself is far from the problem—the Core Ultra X7 368H carries an 87th percentile ranking against all CPUs in the database, with an average benchmark score of 40518. Its nearest rivals include the Intel Core 7 253PE (deltaPct -0.1), Intel Core 5 223PE (deltaPct -0.2), AMD Ryzen 9 7940H (deltaPct 0.2), and Intel Xeon 6507P (deltaPct 0.2). These tiny deltas indicate the processor is competitive with mid-range and even some high-end mobile chips from previous generations.

The GPU, however, tells a different story. The AMD Radeon 880M sits at only the 43rd percentile against all GPUs, with an average benchmark score of 8436. Its nearest rivals are the NVIDIA GeForce GTX 675MX (deltaPct 0.1), NVIDIA GeForce MX330 (deltaPct -0.3), AMD Radeon HD 8870M (deltaPct -0.3), and AMD Radeon R9 M375X (deltaPct 1.3). These are all older discrete mobile GPUs from roughly a decade ago, which contextualizes the 880M’s position: it performs like a mid-range discrete GPU from the 2012-2014 era, despite being a modern integrated solution. The gap between the CPU’s high percentile and the GPU’s mediocre percentile explains why the combo rank is so low—Doom is heavily GPU-bound at most settings, and the 880M simply cannot keep pace with the processor’s capabilities.

Benchmark results indicate that the combo’s rank is consistent with the GPU’s PassMark G3D score of 7615 and its DirectX 11 score of 73, which are modest figures for a modern title. The GPU’s 3DMark Steel Nomad DX12 score of 535 further underscores its limited rasterization performance. In contrast, the CPU’s Cinebench R23 multi-core score of 28221 and single-core score of 3984 demonstrate substantial headroom that remains untapped in this game, as the frame rates are dictated almost entirely by the graphics subsystem.

Settings Recommendations

The measured FPS data provides a clear hierarchy of playability across the four settings presets. At 1920x1080, the Low preset delivers an average of 90 FPS, which is the only configuration in the entire dataset that approaches high-refresh-rate territory. Medium at 1080p drops to 78 FPS average, still comfortably above the 60 FPS threshold that most players consider the minimum for a smooth experience. High at 1080p falls to 66 FPS average, which remains playable but begins to show signs of strain. Ultra at 1080p drops further to 54 FPS average, dipping below the 60 FPS bar.

The recommended preset for the best experience is Medium at 1920x1080, which offers a 78 FPS average with a minimum of 66 FPS and a maximum of 90 FPS. This setting provides a meaningful visual upgrade over Low while maintaining a frame rate that is 18% higher than High and 44% higher than Ultra at the same resolution. The minimum of 66 FPS ensures that even during intense combat sequences, the frame rate stays above the 60 FPS threshold, which is critical for a game as fast-paced as Doom. Low at 1080p offers higher raw performance at 90 FPS, but the visual compromise is substantial, and the gain over Medium is only 15%—not enough to justify the graphical downgrade for most users.

At 2560x1440, no preset achieves a 60 FPS average. Low comes closest at 58 FPS, followed by Medium at 51 FPS, High at 43 FPS, and Ultra at 35 FPS. The 1440p Low setting is technically playable but leaves no headroom for frame drops, as the minimum is not recorded but the average sits just below the 60 FPS line. At 3840x2160, all presets are below 32 FPS, with Low at 31 FPS, Medium at 27 FPS, High at 23 FPS, and Ultra at 19 FPS. These figures render 4K effectively unplayable for this title, regardless of settings.

For the best overall experience, the data supports Medium at 1080p as the sweet spot. It balances visual fidelity with performance, delivering a 78 FPS average that exceeds the 60 FPS target while maintaining a minimum of 66 FPS. Players prioritizing maximum smoothness over visuals could opt for Low at 1080p, but the Medium preset’s combination of framerate and graphical quality makes it the most balanced choice in the measured data.

Resolution Scaling

The FPS drop from 1080p to 4K reveals a system that is overwhelmingly GPU-limited. At 1080p Medium, the average is 78 FPS. Moving to 1440p Medium drops the average to 51 FPS, a 35% reduction. At 4K Medium, the average falls to 27 FPS, a 65% reduction from the 1080p figure and a 47% reduction from 1440p. This scaling pattern is characteristic of a GPU that runs out of pixel throughput and memory bandwidth as resolution increases.

The Radeon 880M’s memory configuration is system-shared, meaning its bandwidth is system dependent rather than fixed. This architecture struggles at higher resolutions because the integrated GPU must compete with the CPU for the same LPDDR5X memory pool. The dual-channel memory bus provides 153.6 GB/s of bandwidth, but this is shared between the processor and graphics subsystem, creating a bottleneck at 1440p and above. The scaling from 1080p to 1440p shows a 35% drop at Medium settings, which is steeper than the 25% resolution increase would suggest, indicating that memory bandwidth constraints amplify the performance penalty.

The 4K results are particularly telling. At 4K Low, the average is 31 FPS, which is only 34% of the 1080p Low average of 90 FPS. This dramatic falloff—a 66% reduction—demonstrates that the 880M’s 16 ROPs and 48 TMUs are severely overtaxed at 4K. The pixel rate of 46.40 GPixel/s and texture rate of 139.2 GTexel/s are insufficient for the 8.3 million pixels of 4K, especially when combined with the system-shared memory overhead. The data indicates that this combo is best suited for 1080p gaming, with 1440p being a marginal stretch and 4K being outside the range of playability.

The pattern across all settings is consistent: the GPU’s performance ceiling is reached well before the CPU’s capabilities are exhausted. The Core Ultra X7 368H’s 16 cores and 5.00 GHz boost clock provide ample processing power, but the 880M’s 768 shading units and 4.454 TFLOPS of FP32 performance simply cannot sustain high frame rates at higher resolutions. The 1080p to 1440p drop of 35% at Medium, and the 1440p to 4K drop of 47% at Medium, both point to a GPU that is the limiting factor in every scenario.

Measured FPS Breakdown

At 1920x1080, the measured results show a clear progression across settings. Low averages 90 FPS, making it the only preset in the entire dataset to break the 90 FPS barrier. Medium averages 78 FPS, with a recorded minimum of 66 FPS and maximum of 90 FPS, indicating that the frame rate fluctuates within a 24 FPS range during gameplay. High averages 66 FPS, which is exactly at the 60 FPS threshold but leaves little margin for demanding scenes. Ultra averages 54 FPS, falling below the 60 FPS line and representing a 40% reduction from Low.

At 2560x1440, the performance drops become more pronounced. Low averages 58 FPS, which is 36% lower than the 1080p Low figure. Medium averages 51 FPS, with a minimum of 43 FPS and maximum of 58 FPS—the minimum is concerning because it dips well below 45 FPS during intense moments. High averages 43 FPS, a 35% reduction from the 1080p High score. Ultra averages 35 FPS, which is 35% lower than the 1080p Ultra score, showing that the scaling penalty is consistent across settings at this resolution.

At 3840x2160, the results are uniformly poor. Low averages 31 FPS, Medium averages 27 FPS (with a minimum of 23 FPS and maximum of 31 FPS), High averages 23 FPS, and Ultra averages 19 FPS. The Medium preset’s minimum of 23 FPS means that even the most forgiving scenes at 4K fail to reach 30 FPS, which is generally considered the absolute floor for playability. The gap between Low and Ultra at 4K is only 12 FPS, suggesting that the GPU is so saturated that settings changes have diminishing returns.

The data shows that the 1080p Medium preset is the only configuration that maintains a minimum above 60 FPS. At 1440p, even Low fails to hit a 60 FPS average, coming in at 58 FPS. At 4K, all presets are below 32 FPS. This breakdown reinforces the conclusion that 1080p is the only viable resolution for this combo, and Medium is the highest setting that keeps the frame rate consistently above the 60 FPS target.

GPU Role

The AMD Radeon 880M is an integrated GPU based on the RDNA 3.5 architecture, built on a 4 nm process by TSMC. It features 768 shading units, 48 TMUs, and 16 ROPs, with 12 ray tracing cores. The GPU operates at a base clock of 400 MHz and boosts to 2900 MHz, which is a substantial boost multiplier of 7.25x. Its FP32 performance is rated at 4.454 TFLOPS, with FP16 performance at the same figure due to a 1:1 ratio. The pixel rate is 46.40 GPixel/s and the texture rate is 139.2 GTexel/s.

The memory subsystem is entirely system-shared, with the GPU relying on the CPU’s LPDDR5X memory. The bus width and bandwidth are listed as system dependent, meaning they vary based on the host system’s configuration. In this case, the Core Ultra X7 368H supports dual-channel LPDDR5X with a memory bandwidth of 153.6 GB/s, but this bandwidth is shared between the CPU and GPU. This shared memory architecture is a significant limitation for gaming, as the GPU cannot access dedicated high-bandwidth VRAM.

Benchmark results for the GPU show a PassMark G3D score of 7615, which places it in the 43rd percentile of all GPUs. Its nearest rivals include the NVIDIA GeForce GTX 675MX (deltaPct 0.1) and the NVIDIA GeForce MX330 (deltaPct -0.3), both of which are older discrete mobile GPUs. The GPU’s DirectX 11 score of 73 and DirectX 12 score of 32 in PassMark indicate that it performs better in older APIs, which is relevant for Doom since the game supports both Vulkan and OpenGL 4.6. The 3DMark Steel Nomad DX12 score of 535 is low, reflecting the GPU’s limited modern API performance.

In Doom, the GPU’s role is decisive. The measured FPS data shows that the GPU’s performance ceiling is reached at 1080p Medium, where it delivers 78 FPS. At higher resolutions, the GPU’s limited ROP count and shared memory bandwidth cause precipitous drops. The boost clock of 2900 MHz helps at lower resolutions, but the 16 ROPs are insufficient for pixel-heavy workloads at 1440p and 4K. The GPU’s 4.454 TFLOPS of compute power is adequate for 1080p gaming, but the memory bottleneck amplifies at higher resolutions. The data indicates that the 880M is best treated as a 1080p gaming solution, with 1440p being a compromise and 4K being out of reach.

CPU Role

The Intel Core Ultra X7 368H 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 2.00 GHz and a boost clock of 5.00 GHz, with a TDP of 25 W. The cache hierarchy includes 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3 cache. The processor supports dual-channel LPDDR5X memory with a bandwidth of 153.6 GB/s and uses an Intel BGA 2540 socket.

The CPU’s benchmark scores are strong. In Cinebench R23, it scores 28221 multi-core and 3984 single-core. In Cinebench R20, the scores are 11852 multi-core and 1673 single-core. PassMark multithread score is 32956, with a single-thread score of 4005. The CPU’s percentile vs all CPUs is 87, and its average benchmark score is 40518. Its nearest rivals in the database include the Intel Core 7 253PE (deltaPct -0.1), Intel Core 5 223PE (deltaPct -0.2), AMD Ryzen 9 7940H (deltaPct 0.2), and Intel Xeon 6507P (deltaPct 0.2). These deltas are all within 0.2%, indicating that the Core Ultra X7 368H is statistically tied with these processors in aggregate CPU benchmarks.

In Doom, the CPU’s role is secondary but not negligible. The game is primarily GPU-bound, as evidenced by the FPS scaling with resolution. However, the CPU’s 16 cores and high boost clock ensure that there is no CPU-side bottleneck at any tested setting. The 5.00 GHz boost clock provides strong single-thread performance, which is important for game logic and physics. The 18 MB of L3 cache helps reduce memory latency, while the 2.5 MB L2 per core provides ample on-die storage for frequently accessed data.

The PassMark data compression score of 312927 and data encryption score of 25228 indicate strong general-purpose performance, but these are not directly relevant to gaming. The physics score of 2857 is more relevant, as Doom’s physics and collision detection rely on CPU performance. The CPU’s 25 W TDP is low for a 16-core part, but the Panther Lake architecture is designed for efficiency. The data shows that the CPU is more than capable of feeding the GPU with draw calls and game state updates, as the frame rates are consistently limited by the GPU rather than the processor.

The CPU’s memory support for LPDDR5X is shared with the GPU, which is a potential bottleneck. The dual-channel bus provides 153.6 GB/s, but this is split between CPU and GPU workloads. In Doom, the GPU’s memory demands at 1440p and 4K likely starve the CPU of bandwidth, further exacerbating the performance drop at higher resolutions. However, at 1080p, the CPU has sufficient bandwidth to maintain high frame rates, as evidenced by the 90 FPS average at Low settings. The data suggests that the CPU is not the limiting factor in this combo; rather, the integrated GPU’s shared memory architecture creates a system-level bottleneck that holds back the entire platform.
