Doom

# How This Combo Ranks

The Intel Core Ultra 5 125H paired with the NVIDIA GeForce RTX 5070 Mobile lands at rank 2,056 out of 3,712 tested combinations in Doom. This places the combo in the 55th percentile of all tested systems, meaning it outperforms a slight majority of the field but sits firmly in the middle of the pack rather than at the top. The rank reflects a balanced pairing where neither component dramatically boosts the other, and the measured frame rates across resolutions confirm a system that delivers playable performance at most settings but requires compromises at the highest visual quality levels.

When breaking down the individual components, the CPU's average benchmark score of 27,507 places it within 0.1% of the AMD Ryzen 7 5800 (27,535) and 0.3% behind both the Intel Core i5-12600K and AMD Ryzen 7 5700X (each at 27,578). The GPU's average score of 29,928 sits 0.1% below the NVIDIA GeForce RTX 3070 Ti (29,945), 0.5% above the RTX 2080 Ti (29,783), and 0.6% behind the AMD Radeon RX 6800 (30,095). These narrow margins indicate that the combo's mid-pack ranking stems from components that are competitive with previous-generation high-end hardware but not dominant in absolute terms.

The CPU's percentile standing against all processors is 79, while the GPU holds a 75th percentile against all graphics cards. These similar relative positions suggest neither part is a bottleneck in the pairing; instead, the system behaves as a cohesive unit that delivers frame rates consistent with its aggregate hardware class. The combo's rank in Doom specifically reflects how this balanced configuration handles the game's engine demands, which favor both strong single-thread performance and substantial GPU throughput.

GPU Role

The NVIDIA GeForce RTX 5070 Mobile brings 8 GB of GDDR7 memory across a 128-bit bus, yielding a bandwidth of 384.0 GB/s. Memory runs at 1500 MHz with 24 Gbps effective speed, while the GPU core operates at a base clock of 907 MHz and boosts up to 1425 MHz. These specifications position the card as a capable mobile solution, though the 8 GB capacity becomes a limiting factor at higher resolutions where texture data and framebuffer requirements scale aggressively.

The GPU's compute resources include 4,608 shading units, 144 texture mapping units, and 48 raster output pipelines. It also features 36 ray tracing cores and 144 tensor cores, supporting DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The pixel rate of 68.40 GPixel/s and texture rate of 205.2 GTexel/s provide the raw throughput needed for Doom's fast-paced rendering, while FP32 performance of 13.13 TFLOPS (with FP16 at 13.13 TFLOPS at 1:1 ratio) handles the game's compute shaders efficiently.

In Doom specifically, the GPU's role becomes evident in the scaling pattern across settings. At 4K Ultra, the average frame rate drops to 47 FPS, suggesting the card's 8 GB framebuffer and compute resources are stretched thin by the highest quality preset's demands. The boost clock of 1425 MHz is modest by modern standards, yet the architecture's efficiency compensates, as evidenced by the jump from 47 FPS at 4K Ultra to 58 FPS at 4K High — an 11 FPS improvement that indicates the Ultra preset introduces rendering features that disproportionately tax the GPU.

The GPU's benchmark scores reinforce its position: PassMark G3D scores 20,355, while Geekbench OpenCL reaches 122,238 and Vulkan hits 116,960. These synthetic results align with the measured in-game performance, showing a card that competes with desktop RTX 3070 Ti-class hardware (0.1% difference) while consuming only 50 W TDP. The 21,900 million transistors on a 181 mm² die at 5 nm process node demonstrate the efficiency gains of the Blackwell 2.0 architecture.

Resolution Scaling

The frame rate progression from 1080p to 4K reveals where the bottleneck shifts between CPU and GPU. At 1080p Low, the combo achieves 224 FPS, but this drops to 145 FPS at 1440p Low and 79 FPS at 4K Low. The scaling from 1080p to 1440p represents a 35% performance reduction, while moving from 1440p to 4K costs another 46%. This steep decline indicates GPU-bound behavior at lower settings, where the CPU can feed frames faster than the GPU can render them.

At High settings, the same pattern emerges: 165 FPS at 1080p drops to 107 FPS at 1440p (35% reduction) and then to 58 FPS at 4K (46% reduction from 1440p). The consistency of these percentages across Low and High presets confirms that resolution scaling is the dominant factor, with the GPU's fill rate and bandwidth determining the ceiling. The 384.0 GB/s memory bandwidth becomes increasingly stressed as pixel count rises, though the 8 GB capacity also plays a role at 4K where texture streaming may exceed available VRAM.

The Medium preset tells a similar story: 195 FPS at 1080p falls to 126 FPS at 1440p and 68 FPS at 4K. The percentage drops of 35% and 46% respectively mirror the other presets, showing that the GPU's compute resources scale predictably with resolution. Notably, the 4K Medium result includes measured minimum and maximum values of 58 and 79 FPS, which exactly match the average FPS of the Low and High presets at that resolution — a coincidence that highlights the narrow performance band at 4K.

Ultra settings exacerbate the GPU bottleneck. At 1080p Ultra, the combo still manages 135 FPS, but 1440p Ultra drops to 87 FPS (36% reduction) and 4K Ultra falls to 47 FPS (46% reduction from 1440p). The 4K Ultra result of 47 FPS sits below the 60 FPS threshold commonly associated with smooth gameplay, indicating that the GPU cannot sustain high-refresh experiences at maximum quality on 4K displays. The consistent 35-36% and 46% reductions across all presets suggest the CPU is never the limiting factor — the GPU's rendering pipeline determines the scaling curve.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest performance across all settings. Low settings produce an average of 224 FPS, Medium reaches 195 FPS with minimum and maximum values of 166 and 224 FPS, High achieves 165 FPS, and Ultra still manages 135 FPS. The gap between Low and Ultra is 89 FPS, representing a 40% performance penalty for maximum visual quality. Even at Ultra, the 135 FPS average comfortably exceeds the refresh rates of most 1080p displays, making this resolution the sweet spot for high-refresh gaming.

Moving to 2560x1440, the averages step down predictably: Low delivers 145 FPS, Medium hits 126 FPS with minimum and maximum values of 107 and 145 FPS, High reaches 107 FPS, and Ultra drops to 87 FPS. The 4K Medium minimum and maximum values (58 and 79 FPS) mirror the Low and High averages, but at 1440p, the Medium range of 107-145 FPS brackets the High average exactly at 107 FPS. This suggests the Medium preset at 1440p offers headroom above the High preset's average, making it a viable choice for players seeking a balance between quality and frame rate.

At 3840x2160, performance becomes more constrained. Low averages 79 FPS, Medium averages 68 FPS with a range of 58-79 FPS, High drops to 58 FPS, and Ultra falls to 47 FPS. The spread from Low to Ultra at 4K is 32 FPS, which is a narrower absolute range than at lower resolutions despite the larger percentage differences. This compression occurs because the GPU approaches its throughput limits at 4K, and even reducing settings cannot fully compensate for the pixel count burden. The 4K results indicate that only Low and Medium presets maintain averages above 60 FPS, while High and Ultra require accepting sub-60 FPS gameplay.

The data shows a consistent pattern: each resolution step down (from 4K to 1440p to 1080p) roughly doubles the frame rate at equivalent settings. Doubling from 4K to 1440p is not exact — 58 to 107 FPS at High represents 1.84x — but the trend holds across presets. The 1080p to 1440p step yields approximately 1.5x improvement, reflecting the pixel count reduction from 3.7 million to 2.1 million pixels (a 43% reduction). This arithmetic confirms that the system scales predictably with resolution, with no anomalous bottlenecks or thermal throttling visible in the measured data.

CPU Role

The Intel Core Ultra 5 125H features 14 cores and 18 threads, with a base clock of 3.60 GHz and boost clock of 4.50 GHz. This Meteor Lake architecture chip, built on Intel's 7 nm process, includes 18 MB of shared L3 cache, 2 MB of L2 cache per core, and 112 KB of L1 cache per core. The CPU supports DDR5 memory on a dual-channel bus with 89.6 GB/s bandwidth, which feeds the GPU through PCIe Gen 5 connectivity. The 28 W TDP indicates a power-efficient mobile design that still delivers desktop-like performance in burst workloads.

In Doom, the CPU's role is primarily to maintain frame pacing and handle game logic, physics, and AI. The PassMark multithread score of 21,100 and Cinebench R23 multi-core score of 12,804.5 demonstrate strong parallel throughput, while the single-thread scores (3,399 on PassMark, 1,647.5 on Cinebench R23) ensure responsive gameplay in scenarios that rely on a single primary thread. The 4.50 GHz boost clock provides the high-frequency headroom that Doom's engine utilizes for its core simulation loop.

The CPU's benchmark scores place it within 0.1% of the AMD Ryzen 7 5800 and 0.3% of the Intel Core i5-12600K in average performance, meaning the 125H keeps pace with established desktop processors from previous generations. The 79th percentile standing against all CPUs confirms this is a well-above-average mobile processor, though not a flagship. The 18 threads allow the CPU to handle background tasks and streaming without starving the game of processing resources, which is particularly relevant in Doom's combat-heavy scenes where multiple enemy AI routines run concurrently.

The CPU's memory bandwidth of 89.6 GB/s feeds the GPU's 384.0 GB/s bandwidth through the PCIe Gen 5 interface, ensuring that data transfer between CPU and GPU is not a bottleneck. The measured FPS patterns — particularly the consistent 35-46% reductions across resolutions — indicate that the CPU maintains adequate frame delivery even at 1080p Low where the GPU is less stressed. At 1080p Low's 224 FPS, the CPU sustains frame times below 4.5 ms, which aligns with its boost clock capability and 18 MB L3 cache keeping frequently accessed game data close to the cores.

Settings Recommendations

The measured data suggests that the optimal balance of visual quality and frame rate depends heavily on the target display resolution. At 1080p, all settings deliver playable frame rates, with Ultra averaging 135 FPS and High at 165 FPS. The 30 FPS difference between these presets is noticeable for competitive play, but the visual improvements of Ultra may justify the trade-off for single-player experiences. For players prioritizing smoothness, High offers a 22% improvement over Ultra while retaining most visual features.

At 1440p, Medium emerges as the most balanced choice. The average of 126 FPS with a range of 107-145 FPS provides sufficient headroom above 60 FPS for adaptive sync displays, while High (107 FPS) and Ultra (87 FPS) still meet the 60 FPS threshold comfortably. The Medium preset's minimum of 107 FPS exactly matches the High average, suggesting that Medium maintains more consistent frame times during intense scenes. Players with 1440p 144 Hz monitors should favor Medium for the best combination of fluidity and visual fidelity.

At 4K, the recommendations tighten considerably. Low (79 FPS) and Medium (68 FPS) are the only presets averaging above 60 FPS, with Medium offering a meaningful quality improvement over Low for just 11 FPS. High (58 FPS) and Ultra (47 FPS) fall short of the 60 FPS target, making them viable only for players who prioritize visual quality over frame rate smoothness. The Medium preset's minimum of 58 FPS matches the High average, indicating that even Medium can experience dips below 60 FPS in demanding scenes, so players sensitive to frame drops may prefer Low at 4K.

Across all resolutions, the Ultra preset consistently costs 20-30% performance compared to High. The data shows that High at 1440p (107 FPS) outperforms Low at 4K (79 FPS) by 35%, meaning players should prioritize resolution over settings when both cannot be maxed. The Medium preset appears to offer the best performance-per-visual-quality ratio at every resolution, with the 4K Medium result (68 FPS) providing a playable experience that is only 14% slower than 4K Low while delivering noticeably better image quality.
