Doom

The Intel Core Ultra 7 155H and NVIDIA GeForce RTX 4070 Mobile combination delivers a robust performance profile in Doom, with frame rates that scale predictably with resolution and settings. The data indicates a system well-suited for high-refresh-rate 1080p gaming, while still maintaining playable performance at 4K with adjusted settings. This analysis breaks down the measured results across all tested configurations.

Resolution Scaling

The transition from 1080p to 4K reveals a classic GPU-bound scaling pattern, with frame rates dropping proportionally to the increase in pixel count. At the High preset, the average frame rate falls from 167 FPS at 1920x1080 to 108 FPS at 2560x1440, a 35% reduction. Moving further to 3840x2160, the average drops to 59 FPS, which represents a 65% decrease from the 1080p figure. This steep decline indicates that the GPU is the primary limiting factor at higher resolutions, as the CPU has ample headroom to feed frames at 1080p.

The scaling behavior across all settings follows a consistent pattern. At Low settings, the frame rate goes from 227 FPS at 1080p to 147 FPS at 1440p, then to 80 FPS at 4K. The Medium preset shows a similar trajectory: 198 FPS, 128 FPS, and 69 FPS respectively. The Ultra preset, being the most demanding, shows 137 FPS at 1080p, 89 FPS at 1440p, and 48 FPS at 4K. The consistent proportional drops across all presets reinforce that resolution scaling is purely a function of pixel throughput, with no sudden bottlenecks appearing at any specific resolution.

At 1080p, the frame rates are exceptionally high, exceeding 200 FPS on Low settings. This suggests that the CPU is capable of keeping up with the GPU's output, as the frame rate is not artificially capped. The 227 FPS figure at Low 1080p indicates that the Core Ultra 7 155H does not become a limiting factor at this resolution, allowing the RTX 4070 Mobile to perform at its full potential. The gap between Low and Ultra at 1080p is 90 FPS, which is a substantial range that gives users clear control over their performance targets.

The 4K results show that Ultra settings push the combo to 48 FPS average, which is below the 60 FPS threshold many consider ideal. However, the Medium preset at 4K achieves 69 FPS, indicating that a single step down in settings recovers significant performance. The data shows that 4K gaming is viable with this hardware, but it requires a willingness to adjust settings away from the maximum preset.

GPU Role

The NVIDIA GeForce RTX 4070 Mobile is the dominant component in this pairing, particularly as resolution increases. The GPU's 8 GB of GDDR6 memory on a 128-bit bus provides 256.0 GB/s of bandwidth, which is sufficient for Doom's texture-heavy environments at the tested resolutions. The memory clock runs at 2000 MHz, with an effective data rate of 16 Gbps. The GPU operates with a base clock of 1395 MHz and a boost clock of 1695 MHz, which are the figures that determine the sustained performance during gameplay.

The GPU's architecture, Ada Lovelace, is built on a 5 nm process at TSMC, with 22,900 million transistors on a 188 mm² die. The chip, designated AD106, contains 4608 shading units, 144 texture mapping units, and 48 raster output pipelines. These specifications translate to a pixel rate of 81.36 GPixel/s and a texture rate of 244.1 GTexel/s. The FP32 performance is rated at 15.62 TFLOPS, which provides the raw compute power needed for modern game rendering. The GPU also includes 36 ray tracing cores and 144 tensor cores, though Doom's traditional rendering pipeline does not heavily leverage these features.

The performance gap between Low and Ultra settings at each resolution shows the GPU's scaling efficiency. At 1080p, the difference is 90 FPS (227 vs 137), at 1440p it is 58 FPS (147 vs 89), and at 4K it is 32 FPS (80 vs 48). This narrowing gap at higher resolutions is typical, as the fixed cost of pixel processing becomes a larger portion of the total frame time. The GPU's utilization is near maximum at 4K, where even the Low preset produces only 80 FPS, indicating that the render pipeline is fully occupied.

The GPU's benchmark scores provide context for its gaming performance. In PassMark G3D, it scores 19587, placing it in the 73rd percentile among all GPUs. Its nearest rivals include the AMD Radeon RX 6700 XT with a score of 27425 (0% delta) and the NVIDIA GeForce RTX 3090 with 27565 (-0.5% delta). These comparisons show that the mobile RTX 4070 performs on par with desktop GPUs from a previous generation, which is notable for a mobile part. The OpenCL score of 109197 and Vulkan score of 108367 in Geekbench further corroborate its compute capabilities.

The CPU's architecture, Meteor Lake, is built on Intel's 7 nm process. It supports DDR5 memory with a dual-channel configuration, providing a memory bandwidth of 89.6 GB/s. This bandwidth is sufficient to feed the GPU's 256.0 GB/s of video memory bandwidth without creating a data bottleneck. The PCIe Gen 5 interface with 8 lanes (CPU only) ensures that the GPU has a fast connection to the rest of the system, though the GPU itself uses PCIe 4.0 x8.

In the context of Doom's performance, the CPU's role becomes more apparent at lower resolutions. At 1080p Low, the 227 FPS average indicates that the CPU can process game logic at a rate that supports over 200 frames per second. The fact that the frame rate does not plateau at a lower value suggests that the CPU is not the limiting component at this resolution. As resolution increases, the GPU becomes the bottleneck, and the CPU's utilization likely decreases, allowing it to handle background tasks without impacting gameplay.

The CPU's 16 cores and 22 threads provide headroom for multitasking, such as running streaming software or background applications while gaming. The boost clock of 4.80 GHz ensures that games which rely on single-threaded performance, like Doom, receive the necessary processing power. The measured FPS data across all resolutions and settings shows no signs of CPU-induced stuttering or frame drops, confirming that the processor is well-matched to the GPU for this game.
