Doom

The Intel Core Ultra 7 265HX paired with the AMD Radeon 890M presents a fascinating case study in integrated graphics performance within a modern, high-core-count mobile platform. The measured data for Doom reveals a configuration that is heavily constrained by its GPU, yet the CPU’s substantial headroom ensures that frame pacing remains predictable across all tested resolutions. This analysis breaks down the measured FPS, the division of labor between the processor and graphics solution, and how this specific combination stacks up against the broader database.

Resolution Scaling

The transition from 1920x1080 to 3840x2160 demonstrates a classic GPU-bound scenario, where the workload on the Radeon 890M increases geometrically while the CPU’s contribution remains relatively static. At 1080p with Low settings, the system produces an average of 95 FPS. Moving to 1440p at the same settings, the average drops to 61 FPS, a reduction of approximately 36%. The scaling becomes more severe when pushing to 4K, where the average falls to 33 FPS, a further 46% decrease from the 1440p result.

This pattern indicates that the limiting component is unambiguously the integrated GPU. The frame rate decay is not linear; it accelerates as resolution increases, which is symptomatic of pixel fill-rate and shading unit limitations. For instance, at High settings, the average FPS goes from 70 at 1080p, to 45 at 1440p, and finally to 24 at 4K. The gap between Low and High settings widens at lower resolutions, suggesting that at 1080p, the GPU still has some headroom to process additional visual effects, but at 4K, even the lowest settings strain the GPU to its limits.

The data implies that the Intel Core Ultra 7 265HX is not a bottleneck in this equation. With a boost clock of 5.30 GHz and 20 cores, the CPU can prepare frames far faster than the Radeon 890M can render them. The scaling pattern is a clear indicator that users seeking higher frame rates should prioritize resolution reduction over graphical feature tweaks, as the GPU’s raw throughput is the primary barrier to performance.

GPU Role

The AMD Radeon 890M is an integrated graphics processor based on the RDNA 3.5 architecture, built on a 4 nm process node. Its performance profile, as measured here, places it in a specific tier that is competitive with older discrete solutions. The GPU’s benchmark scores show a Passmark G3D score of 8076 and a Geekbench Vulkan score of 40808, which are modest figures that align with its integrated nature.

In Doom, the GPU’s role is defined by its shading units (1024) and its reliance on system memory. The GPU’s memory bandwidth is listed as "System Dependent," which means its performance is tied to the speed of the DDR5 memory and the dual-channel interface of the CPU. The boost clock of 2900 MHz is relatively high for an IGP, but the physical constraints of sharing memory bandwidth with the CPU limit its effective throughput.

The measured FPS at 4K Ultra (20 FPS average) versus 1080p Low (95 FPS average) illustrates the GPU’s operational envelope. The GPU is capable of playable frame rates at lower resolutions, but it lacks the raw compute power to handle high pixel counts with advanced settings. The FP32 performance of 5.939 TFLOPS is sufficient for e-sports titles and older AAA games at 1080p, but the data confirms that 4K gaming is not a realistic target for this component, even with the considerable assistance of the Core Ultra 7 processor.

CPU Role

The Intel Core Ultra 7 265HX is a 20-core, 20-thread processor based on the Arrow Lake architecture, with a base clock of 2.60 GHz and a boost clock of 5.30 GHz. Its benchmark scores are substantial, including a Cinebench R23 multicore score of 40642 and a Passmark single-thread score of 4500. These results place it in the 93rd percentile of all CPUs, indicating a high-performance mobile part.

In the context of Doom, the CPU’s role is to feed the GPU with draw calls and physics calculations. The data suggests that the CPU is never the limiting factor. Even at 1080p Low, where the GPU is working hardest relative to its capacity, the average FPS of 95 is likely near the ceiling of what the GPU can output, not the CPU. The CPU’s high single-thread performance, evidenced by its Cinebench R15 single-core score of 578, ensures that the game’s main thread is processed efficiently.

The 30 MB of shared L3 cache is ample for game data, and the 20 cores handle background tasks and threading overhead without impacting frame times. The processor’s memory bandwidth of 102.4 GB/s is a critical resource for the 890M, as the GPU has no dedicated VRAM. The CPU’s ability to maintain high memory throughput directly influences the GPU’s performance, especially at higher resolutions where memory access patterns become more demanding.

Measured FPS Breakdown

The measured data provides a clear matrix of performance across three resolutions and four settings presets. At 1920x1080, the system delivers 95 FPS on Low, 82 FPS on Medium, 70 FPS on High, and 57 FPS on Ultra. The Medium preset shows a minimum FPS of 70 and a maximum of 95, which mirrors the Low preset average, suggesting that the Medium preset is effectively saturating the GPU’s capabilities.

At 2560x1440, the averages drop to 61 FPS on Low, 53 FPS on Medium, 45 FPS on High, and 37 FPS on Ultra. The Medium preset at this resolution shows a minimum of 45 and a maximum of 61, indicating that the frame rate is becoming less stable as the GPU approaches its limits. The difference between Low and Ultra at 1440p is 24 FPS, which is a significant margin that highlights the cost of visual fidelity.

At 3840x2160, the system struggles to maintain playable frame rates. The averages are 33 FPS on Low, 29 FPS on Medium, 24 FPS on High, and 20 FPS on Ultra. The Medium preset records a minimum of 25 FPS, which is below the threshold for smooth gameplay. The data shows that 4K is only viable for static screenshots or very slow-paced scenarios, and even then, only with the lowest settings.

The progression from Low to Ultra at each resolution shows a consistent penalty. At 1080p, the Ultra preset is 40% slower than Low. At 1440p, the penalty is 39%. At 4K, the penalty is also 39%. This consistency suggests that the GPU’s architecture scales predictably with the additional shading and texture work required by higher presets, regardless of resolution.

How This Combo Ranks

Within the database of tested combinations, this specific pairing of the Intel Core Ultra 7 265HX and the AMD Radeon 890M is ranked 2758 out of 2930 combos for Doom. This places it in the bottom 6% of all tested systems, which is a stark contrast to the CPU’s individual high percentile ranking. The combo’s rank is dragged down entirely by the GPU’s performance ceiling.

The GPU’s average benchmark score of 9210 puts it in the 45th percentile of all GPUs, with nearest rivals including the AMD Radeon Vega 8 (deltaPct -0.1) and the NVIDIA GeForce GTX 960 (deltaPct -0.7). These deltas are tiny, indicating that the 890M is statistically equivalent to these older discrete cards in general compute tasks. However, in Doom specifically, the combination’s rank suggests that the game’s engine is particularly sensitive to the GPU’s memory bandwidth limitations.

The CPU’s nearest rivals, such as the Intel Core i7-13790F (deltaPct 0.1) and the AMD Ryzen AI 7 450G (deltaPct -0.2), show that the 265HX is competitive with desktop-class parts. Yet, this raw CPU power does not translate into a high combo rank because the GPU is the definitive bottleneck. The data implies that users would achieve a much higher ranking by pairing this CPU with a discrete GPU, or by accepting that this combo is designed for productivity and light gaming, not high-end FPS titles.
