Doom

The data for Doom on this Intel Core Ultra 5 125H and NVIDIA GeForce RTX 4080 Mobile combination shows a consistent pattern across all measured resolutions and settings. The benchmark results place this combo at rank 1222 out of 3712 tested configurations, indicating a strong but not top-tier position for this title. The measured frames per second range from 61 at 4K Ultra to 288 at 1080p Low, showing that this hardware is capable of handling the game smoothly at most settings, with clear trade-offs between visual fidelity and frame rate.

Settings Recommendations

The measured FPS data reveals that the Ultra preset delivers the most demanding workload, with average frames per second of 173 at 1920x1080, 112 at 2560x1440, and 61 at 3840x2160. At 1080p, the Ultra preset provides a playable experience well above typical refresh rates, while at 1440p it remains smooth for most displays. However, at 4K, the Ultra preset drops to 61 average FPS, which is borderline for high-refresh displays but still acceptable for standard 60Hz monitors.

The High preset offers a better balance for higher resolutions. At 3840x2160, High yields 74 average FPS, which is a 13 FPS improvement over Ultra. At 2560x1440, High reaches 137 average FPS, and at 1920x1080, it hits 212 average FPS. The step from Ultra to High costs some visual quality but provides a meaningful performance buffer, especially at 4K where the frame rate moves from 61 to 74.

Medium settings show even stronger performance gains. At 4K, Medium produces 88 average FPS with a minimum of 75 and maximum of 101. At 1440p, Medium delivers 162 average FPS, and at 1080p, it reaches 251 average FPS. The minimum FPS data for Medium at 1440p is 138, and at 1080p it is 213, showing that frame pacing remains consistent even during demanding scenes.

Low settings are the most performant, with 101 average FPS at 4K, 186 at 1440p, and 288 at 1080p. The jump from Low to Medium at 4K is 13 FPS (from 101 to 88), while at 1080p the gap is 37 FPS (from 288 to 251). This suggests that the Low preset removes enough rendering load to substantially increase frame rates, particularly at lower resolutions where the CPU and GPU are less constrained.

For the best experience per the measured data, the Medium preset at 2560x1440 appears optimal, delivering 162 average FPS with a minimum of 138. This combination provides high frame rates that exceed most monitor refresh rates while maintaining better visual quality than Low. At 4K, Medium is also the recommended choice, as 88 average FPS is smoother than High’s 74 and far better than Ultra’s 61, while the visual difference between Medium and High is typically less impactful than the frame rate gap. For competitive play at 1080p, Low at 288 average FPS offers the highest responsiveness, but Medium at 251 FPS is nearly as fast with improved visuals.

GPU Role

The NVIDIA GeForce RTX 4080 Mobile is built on the Ada Lovelace architecture with a 5 nm process from TSMC. It features 7424 shading units, 232 texture mapping units, and 80 raster operation pipelines. The GPU has 58 ray tracing cores and 232 tensor cores, supporting DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The chip contains 35,800 million transistors on a 294 mm² die, with a transistor density of 121.8 million per mm².

The GPU’s base clock is 1290 MHz with a boost clock of 1665 MHz. Memory runs at 2250 MHz with 18 Gbps effective speed. The 12 GB of GDDR6 memory is connected via a 192-bit bus, providing 432.0 GB/s of bandwidth. The pixel rate is 133.2 GPixel/s, and the texture rate is 386.3 GTexel/s. Floating point performance is rated at 24.72 TFLOPS for both FP32 and FP16 with a 1:1 ratio. The thermal design power is 110 W.

These specifications directly influence Doom’s measured performance. The 12 GB VRAM capacity is sufficient for all tested settings, as none of the resolutions or presets show signs of memory-related bottlenecks. The 432.0 GB/s memory bandwidth supports high texture throughput, which is critical for Doom’s fast-paced environments. The boost clock of 1665 MHz provides the compute headroom needed to achieve the observed frame rates.

The GPU’s benchmark scores corroborate its gaming performance. In PassMark G3D, the RTX 4080 Mobile scores 24926, with a percentile of 81 against all GPUs. The Geekbench OpenCL score is 159575, and Vulkan score is 145807. PassMark compute performance is 11191. These scores place the GPU in the upper tier, with nearest rivals including the NVIDIA GeForce MX570 (average score 38299, delta -0.4%), NVIDIA GeForce RTX 5080 Mobile (38349, delta -0.6%), NVIDIA GeForce RTX 4070 (37648, delta 1.3%), and NVIDIA Tesla P4 (37628, delta 1.3%). The RTX 4080 Mobile’s average benchmark score is 38135.

In Doom, the GPU’s role is evident from the scaling across resolutions. At 1080p, even the Ultra preset reaches 173 average FPS, indicating that the GPU has ample headroom. At 4K, the same preset drops to 61 FPS, showing that the GPU becomes more stressed as pixel count quadruples. The difference between Low and Ultra at 4K is 40 FPS (from 101 to 61), which highlights the GPU’s sensitivity to rendering load. The RTX 4080 Mobile is clearly the primary driver of performance in this game, as the CPU is unlikely to be a limiting factor at these frame rates.

CPU Role

The Intel Core Ultra 5 125H is a mobile processor from the Core Ultra Series 1, based on the Meteor Lake architecture. It has 14 cores and 18 threads, with a base clock of 3.60 GHz and boost clock of 4.50 GHz. The thermal design power is 28 W, and it uses the Intel BGA 2049 socket. The processor is manufactured on Intel’s 7 nm process. Cache configuration includes 112 KB L1 per core, 2 MB L2 per core, and 18 MB shared L3.

The CPU’s memory support is DDR5, depending on the motherboard, with dual-channel memory and a bandwidth of 89.6 GB/s. It supports PCIe Gen 5. The integrated graphics are Arc Xe-LPG 96EU. The processor has a launch MSRP of $375 and is not multiplier unlocked. Its part number is SRMZ4.

In synthetic benchmarks, the Core Ultra 5 125H shows moderate performance. Cinebench R15 multicore score is 2021.5, and single core is 241. R20 multicore is 7161, single core 1010. R23 multicore reaches 12804.5, and single core 1647.5. PassMark multithread score is 21100, and single thread is 3399. The average benchmark score is 27507, with a percentile of 79 against all CPUs. Nearest rivals include the AMD Ryzen 7 5800 (average score 27535, delta -0.1%), Intel Core i5-12600K (27578, delta -0.3%), AMD Ryzen 7 5700X (27578, delta -0.3%), and AMD Ryzen 3 PRO 5355G (27382, delta 0.5%).

For Doom, the CPU’s 14 cores and 18 threads are more than sufficient, as the game is not heavily multithreaded. The boost clock of 4.50 GHz provides strong single-thread performance, which is critical for game logic and frame pacing. The L3 cache of 18 MB helps with data locality, reducing memory latency during intense combat sequences.

The CPU’s role in the measured FPS is indirect, as the GPU is likely the bottleneck at higher settings. Evidence for this comes from the scaling between resolutions. At 1080p Low, the combo achieves 288 average FPS, which is a high enough frame rate that the CPU must keep up with draw calls and physics. If the CPU were limiting, we would see similar FPS across resolutions, but the data shows a clear drop from 288 at 1080p Low to 101 at 4K Low. This indicates that the GPU is the primary constraint in most scenarios.

However, at 1080p Low, the 288 FPS result suggests that the CPU can still feed the GPU effectively. The single-thread score of 3399 in PassMark and R23 single core of 1647.5 indicate strong per-core performance, which is essential for Doom’s engine. The CPU’s memory bandwidth of 89.6 GB/s is adequate for the game’s data streaming requirements. Overall, the Core Ultra 5 125H is not a limiting factor in this combination, allowing the RTX 4080 Mobile to perform near its potential.

How This Combo Ranks

The combination of the Intel Core Ultra 5 125H and NVIDIA GeForce RTX 4080 Mobile ranks 1222 out of 3712 tested combos in Doom. This places it in the top third of all configurations, though not among the elite. The rank of 1222 means that many other CPU-GPU pairings deliver higher frame rates in this game, likely due to more powerful desktop processors or higher-tier mobile GPUs.

The CPU’s position relative to rivals provides context. The Core Ultra 5 125H has an average benchmark score of 27507, which is nearly identical to the AMD Ryzen 7 5800 (27535, delta -0.1%), Intel Core i5-12600K (27578, delta -0.3%), and AMD Ryzen 7 5700X (27578, delta -0.3%). It is slightly ahead of the AMD Ryzen 3 PRO 5355G (27382, delta 0.5%). This indicates that the CPU is competitive with mid-range desktop parts from a few generations ago, but in a mobile form factor.

The GPU’s ranking is higher. The RTX 4080 Mobile has a percentile of 81 against all GPUs, with an average benchmark score of 38135. Its nearest rivals are all within 1.3% in either direction, showing that it sits in a tight performance cluster. The delta values against the MX570 (-0.4%), RTX 5080 Mobile (-0.6%), RTX 4070 (1.3%), and Tesla P4 (1.3%) suggest that the RTX 4080 Mobile is competitive with these parts, though not decisively faster.

The combo rank of 1222 out of 3712 means that roughly two-thirds of tested configurations perform better in Doom. This is likely because the RTX 4080 Mobile, while strong, is not the fastest mobile GPU available, and the Core Ultra 5 125H is a mid-range processor. Combos with higher-ranked CPUs or GPUs would naturally achieve higher frame rates. The measured FPS data supports this, as the 4K Ultra result of 61 FPS is playable but not exceptional, and the 1080p Low result of 288 FPS is high but not record-breaking.

Resolution Scaling

The measured FPS data shows a clear trend of decreasing performance as resolution increases. At Low settings, the frame rate drops from 288 at 1920x1080 to 186 at 2560x1440, a reduction of 102 FPS (35.4%). From 1440p to 2160p, the drop is from 186 to 101, a reduction of 85 FPS (45.7%). The percentage drop from 1080p to 4K is from 288 to 101, a total reduction of 187 FPS (64.9%).

For Medium settings, the pattern is similar. At 1080p, the average FPS is 251. At 1440p, it drops to 162, a reduction of 89 FPS (35.5%). At 4K, it falls to 88, a reduction of 74 FPS (45.7%) from 1440p. From 1080p to 4K, the drop is from 251 to 88, a total reduction of 163 FPS (64.9%).

High settings show the same proportional scaling. At 1080p, the average FPS is 212. At 1440p, it drops to 137, a reduction of 75 FPS (35.4%). At 4K, it falls to 74, a reduction of 63 FPS (46.0%) from 1440p. From 1080p to 4K, the drop is from 212 to 74, a total reduction of 138 FPS (65.1%).

Ultra settings follow the same trend. At 1080p, the average FPS is 173. At 1440p, it drops to 112, a reduction of 61 FPS (35.3%). At 4K, it falls to 61, a reduction of 51 FPS (45.5%) from 1440p. From 1080p to 4K, the drop is from 173 to 61, a total reduction of 112 FPS (64.7%).

These consistent percentage drops across all settings indicate that the performance scaling is resolution-bound rather than settings-bound. The fact that the relative drop from 1080p to 4K is nearly identical (around 65%) across all presets suggests that the GPU is the limiting component. If the CPU were limiting, we would expect the frame rate to plateau at higher resolutions, but instead it continues to drop proportionally, which is characteristic of a GPU-bound scenario. The RTX 4080 Mobile’s rendering capabilities are being fully utilized as resolution increases.
