Doom

The data for Doom with the Intel Core Ultra 7 265HX and AMD Radeon RX 7900M shows a combination that is heavily skewed toward GPU-bound performance at higher resolutions, with the CPU proving more than capable of keeping up even at 1080p. The measured frames per second (FPS) across all settings and resolutions indicate a system that can handle the game smoothly, though the scaling patterns reveal where the bottleneck shifts. The combo ranks 1226th out of 2930 tested combinations, placing it in the upper-middle tier of the database, which is consistent with its strong but not top-tier components.

Resolution Scaling

The transition from 1080p to 4K reveals a classic GPU-bound scaling pattern, with frame rates dropping significantly as pixel count increases. At 1080p with High settings, the combo produces 190 FPS, which falls to 123 FPS at 1440p and then to 67 FPS at 4K. This represents a 35% drop from 1080p to 1440p and a further 45% drop from 1440p to 4K, indicating that the Radeon RX 7900M is the limiting factor at higher resolutions. The GPU’s 16 GB of GDDR6 memory and 576.0 GB/s bandwidth are sufficient for the game’s demands, but the sheer pixel throughput required at 4K overwhelms the 4608 shading units and 192 ROPs.

Looking at the Low preset, the scaling is even more pronounced. At 1080p Low, the system achieves 258 FPS, dropping to 167 FPS at 1440p and 90 FPS at 4K. The percentage drops are 35% and 46%, respectively, which is nearly identical to the High preset scaling. This suggests that even when the graphical workload is reduced, the GPU remains the primary constraint, and the CPU is not holding the system back. The fact that the FPS drop from 1080p to 4K is roughly consistent across presets—around 65% reduction—confirms that resolution scaling is purely a GPU limitation in this title.

The Medium preset shows a similar trend, with 225 FPS at 1080p, 145 FPS at 1440p, and 79 FPS at 4K. The drop from 1080p to 1440p is 36%, and from 1440p to 4K is 45%. For the Ultra preset, the numbers are 155 FPS at 1080p, 100 FPS at 1440p, and 54 FPS at 4K, with drops of 35% and 46%. This uniformity across all four presets is telling: the game’s settings do not change the fundamental scaling behavior, which means the Radeon RX 7900M’s compute capabilities are the defining factor. The CPU’s 20 cores and 20 threads, with a boost clock of 5.30 GHz, are clearly not the bottleneck, as evidenced by the high frame rates even at 1080p where CPU overhead is typically more significant.

Settings Recommendations

Examining the measured FPS rows, the best experience per the data is at the High preset for most users, as it offers a strong balance between visual fidelity and performance. At 1080p High, the system delivers 190 FPS, which is well above the 144 Hz refresh rate of most gaming monitors, and at 1440p High, it still achieves 123 FPS, which is comfortably playable on high-refresh displays. Even at 4K High, the 67 FPS average is acceptable for slower-paced gameplay, though it may not be ideal for competitive play.

The Ultra preset, while visually superior, incurs a significant performance penalty. At 1080p Ultra, the frame rate drops to 155 FPS, a 18% reduction from High, and at 1440p Ultra, it falls to 100 FPS, a 19% drop. At 4K Ultra, the system manages only 54 FPS, which is borderline for smooth gameplay. Given that the High preset provides a substantial frame rate advantage with presumably minor visual differences, the data suggests High is the optimal choice for this combination. The Medium preset offers marginal gains over High—225 FPS versus 190 FPS at 1080p, and 145 FPS versus 123 FPS at 1440p—but these increases are unlikely to be perceptible on most displays, making High the better overall value in terms of performance per visual quality.

For users with 4K displays, the Low preset at 90 FPS might be the only way to achieve high refresh rates, but the visual compromise is severe. The Medium preset at 4K provides 79 FPS, which is a reasonable middle ground, but the data shows that High at 4K is still playable at 67 FPS. Ultimately, the recommendation is to prioritize High settings for the best experience, with Medium as a fallback if higher frame rates are desired at 4K.

GPU Role

The AMD Radeon RX 7900M is the dominant component in this system for Doom’s performance. Its 16 GB of GDDR6 memory on a 256-bit bus provides 576.0 GB/s of bandwidth, which is ample for the game’s textures and assets. The GPU’s base clock of 1825 MHz and boost clock of 2090 MHz, combined with 4608 shading units, deliver the raw compute power needed to drive the high frame rates observed. The memory clock runs at 2250 MHz, translating to 18 Gbps effective, which ensures that memory bandwidth is not a limiting factor at any resolution.

The GPU’s benchmark scores further contextualize its performance. In 3DMark Steel Nomad DX12, it scores 4201, and in Geekbench OpenCL and Vulkan, it achieves 129499 and 158760, respectively. These scores place it in the 94th percentile of all GPUs, indicating strong overall performance. However, its nearest rivals show that it is not at the very top of the heap. The AMD Radeon Pro VII is 0.4% ahead, while the NVIDIA Quadro RTX 6000 is 4.3% ahead, and the AMD Radeon Instinct MI60 is 5.4% behind. The NVIDIA RTX A4500 is 6.3% behind. This places the RX 7900M in a competitive but not dominant position, which aligns with its 4K performance being playable but not exceptional.

The GPU’s 192 ROPs and 288 TMUs are well-suited for a game like Doom, which relies on fast fill rates and texture throughput. The 38.52 TFLOPS of FP32 compute is more than enough for the game’s shading workload, and the 72 ray accelerators, while not heavily utilized in this title, provide future-proofing. The data shows that the GPU is the primary driver of FPS differences between presets, with the Ultra preset’s 54 FPS at 4K being the lowest measured value, confirming that the GPU is fully utilized at that settings/resolution combination.

CPU Role

The Intel Core Ultra 7 265HX plays a supporting role in this system, but its capabilities ensure that it never becomes a bottleneck in Doom. With 20 cores and 20 threads, the CPU provides substantial parallel processing power, which is reflected in its benchmark scores. In Cinebench R23, it scores 40642 in multi-core and 5737 in single-core, while in Cinebench R20, it achieves 17069 and 2409, respectively. These scores place the CPU in the 93rd percentile of all CPUs, indicating strong overall performance.

The CPU’s base clock of 2.60 GHz and boost clock of 5.30 GHz, combined with 30 MB of shared L3 cache, provide ample single-threaded performance for game logic and physics. The PassMark single-thread score of 4500 confirms this, as does the Cinebench R15 single-core score of 578. The CPU’s nearest rivals show that it is competitive with other high-end processors: the Intel Core i7-13790F is 0.1% ahead, the AMD Ryzen AI 7 450G is 0.2% behind, the AMD Ryzen AI Embedded P185 is 0.5% ahead, and the Intel Core Ultra 7 255HX is 0.7% ahead. This clustering suggests that the 265HX is well within the expected performance envelope for its class.

In Doom, the CPU’s role is to feed the GPU with draw calls and physics calculations. At 1080p Low, the system hits 258 FPS, which is a clear indicator that the CPU can handle the game’s demands even at very high frame rates. The fact that the FPS drops are consistent across presets at each resolution suggests that the CPU is not introducing any variability. The CPU’s 55 W TDP is modest for a 20-core part, and its 3 nm process node allows for efficient operation, but these factors are not directly measurable in the FPS data. The CPU’s memory bandwidth of 102.4 GB/s over dual-channel DDR5 is sufficient for the game’s data streaming needs, though it is not a differentiator in this context.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of the combo’s performance across all settings and resolutions. At 1920x1080, the system delivers 258 FPS on Low, 225 FPS on Medium, 190 FPS on High, and 155 FPS on Ultra. The Medium preset includes min and max values of 191 and 258 FPS, respectively, indicating a stable frame delivery. The progression from Low to Ultra shows a 40% reduction in performance, from 258 to 155 FPS, which is consistent with the increasing graphical workload.

At 2560x1440, the frame rates drop to 167 FPS on Low, 145 FPS on Medium, 123 FPS on High, and 100 FPS on Ultra. The Medium preset’s min and max are 124 and 167 FPS, showing a similar spread to 1080p. The drop from Low to Ultra is 40%, matching the 1080p scaling. At 3840x2160, the system achieves 90 FPS on Low, 79 FPS on Medium, 67 FPS on High, and 54 FPS on Ultra. The Medium preset at 4K has min and max values of 67 and 91 FPS, which demonstrates that even at 4K, frame delivery is relatively consistent, though the average is below 60 FPS on Ultra.

Across all resolutions, the scaling from Low to Ultra is remarkably consistent at around 40%, which suggests that the game’s settings have a uniform impact on the GPU workload. The 4K Ultra result of 54 FPS is the only measured value below 60 FPS, making it the only scenario where the system fails to maintain a smooth experience. The 1080p Low result of 258 FPS is the highest, and it is likely limited by the game’s engine or the display’s refresh rate rather than the hardware itself.
