Doom

The AMD Ryzen 9 8945HX paired with the NVIDIA GeForce RTX 5070 Mobile delivers a formidable performance profile in Doom, securing the 2056th position out of 3712 tested combinations. This places the combo in the upper-middle tier of the database, with roughly 55% of tested configurations ranking ahead of it. While this percentile might seem modest, it is important to contextualize that the database includes many desktop-class behemoths and multi-GPU setups; for a mobile platform, this ranking reflects a balanced and capable pairing. The data indicates that this combo is not a top-tier enthusiast configuration, but it is far from a bottlenecked or underpowered setup, offering a smooth experience across most resolution and settings combinations tested.

How This Combo Ranks

The combo’s rank of 2056 out of 3712 is a direct indicator of its standing within the broader test suite. This places it in the 44.6th percentile of all combinations, meaning it outperforms 44.6% of tested systems while trailing 55.4%. This is a mid-pack result, but the nature of the ranking is heavily skewed by the inclusion of extreme hardware. The CPU alone holds a 95th percentile ranking among all processors, suggesting that the central processor is a top-tier component, while the GPU sits at the 75th percentile. The combined rank of 2056 is therefore dragged down by the GPU, which, while solid, is not as elite as the CPU. This dynamic is consistent with a laptop configuration where the CPU is a flagship model but the GPU is a mid-to-high-end mobile part. In practical terms, this ranking means that for Doom, the combo will deliver high frame rates, but it will not break records or lead the charts.

CPU Role

The AMD Ryzen 9 8945HX is a 16-core, 32-thread processor based on the Zen 4 architecture, codenamed Dragon Range. It operates with a base clock of 2.50 GHz and can boost up to 5.40 GHz, providing substantial single-thread and multi-thread headroom. This is a mobile-centric chip with a 55 W TDP, designed for high-performance laptops. In the context of Doom, which is a well-optimized title that scales reasonably well with multi-core processors, the CPU’s 16 cores and 32 threads ensure that there is no processing bottleneck. The benchmark data supports this, with a Cinebench R23 multi-core score of 42713 and a single-core score of 6030, both indicating exceptional performance. The PassMark multi-thread score of 51405 further confirms the CPU’s strength in threaded workloads. For this game, the CPU’s role is to feed the GPU with enough draw calls and physics calculations; given its high core count and boost clock, it is more than capable of doing so at all tested settings. The CPU’s generation is Ryzen 9 (Zen 4 Dragon Range), and it sits in the 95th percentile against all CPUs, meaning it is faster than 95% of processors in the database. This headroom is crucial for maintaining high frame rates at lower resolutions where CPU load is higher.

GPU Role

The NVIDIA GeForce RTX 5070 Mobile is the graphical workhorse here, featuring 8 GB of GDDR7 memory on a 128-bit bus with a bandwidth of 384.0 GB/s. Its architecture is Blackwell 2.0, built on a 5 nm process. The GPU has a base clock of 907 MHz and a boost clock of 1425 MHz, with memory running at 1500 MHz (24 Gbps effective). The 8 GB VRAM is a critical factor at higher resolutions and settings; while it is sufficient for Doom at 1080p and 1440p, the data suggests that it becomes a limiting factor at 4K Ultra settings. The GPU’s PassMark G3D score is 20355, placing it at the 75th percentile among all GPUs. This score puts it in close competition with the NVIDIA GeForce RTX 3070 Ti, which has an average score of 29945 (deltaPct -0.1%), and the RTX 2080 Ti, which scores 29783 (deltaPct 0.5%). The RTX 5070 Mobile also sits near the AMD Radeon RX 6800 (30095, deltaPct -0.6%) and RX 6700 (30433, deltaPct -1.7%). This indicates that the mobile GPU performs on par with previous-generation desktop high-end cards, which is impressive for a laptop part. In Doom, the GPU is the primary driver of frame rates, especially at higher resolutions; the data shows that the GPU’s performance scales predictably with resolution and settings, with the 8 GB VRAM being the primary constraint at 4K Ultra.

Measured FPS Breakdown

The measured frame rates tell a clear story of a capable but not unlimited system. At 1920x1080, the combo is exceptionally powerful. With Low settings, the average FPS is 224, which drops to 195 at Medium, 165 at High, and 135 at Ultra. These figures are all above 60 FPS, and even the most demanding setting (Ultra) remains highly playable. The minimum FPS at Medium is 166, which is still well above refresh-rate thresholds for most monitors. Moving to 2560x1440, the performance remains strong but shows a noticeable step down. Low settings yield 145 FPS average, Medium produces 126, High gives 107, and Ultra drops to 87. The minimum FPS at Medium is 107, which is still smooth. At 3840x2160, the system starts to strain. Low settings deliver 79 FPS average, Medium drops to 68, High falls to 58, and Ultra dips below the 60 FPS target to 47 FPS. The minimum FPS at Medium is 58, indicating that even at this resolution, the system can maintain playable frame rates with some settings adjustments. The data shows a clear trend: the combo is best suited for 1080p and 1440p gaming, where it can hit high refresh rates, while 4K gaming requires dropping to High or Medium settings to maintain smoothness.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and refresh rate. For 1920x1080, the Ultra preset delivers an average of 135 FPS, which is excellent for high-refresh monitors. There is no reason to lower settings here, as even the most demanding preset maintains a high frame rate. For 2560x1440, the High preset is the sweet spot, providing 107 FPS average, which is smooth and visually detailed. Dropping to Medium increases the average to 126 FPS, but the visual fidelity loss is not worth the extra frames unless the display is 144 Hz or higher. For 3840x2160, the Medium preset is recommended, yielding 68 FPS average. High settings drop to 58 FPS, which is borderline for smooth gameplay, while Low settings are too visually compromised at this resolution. The Ultra preset at 4K is not recommended due to the 47 FPS average, which will feel stuttery. In summary, for a balanced experience, use Ultra at 1080p, High at 1440p, and Medium at 4K.

Resolution Scaling

The frame rate scaling from 1080p to 4K is informative about the system’s bottleneck. At High settings, the average FPS drops from 165 at 1920x1080 to 107 at 2560x1440, a 35.2% reduction, and then to 58 at 3840x2160, a further 45.8% reduction from 1440p. This steep drop-off as resolution increases indicates that the GPU is the limiting component at higher resolutions. The CPU, with its 16 cores and high boost clock, has ample headroom to feed the GPU at all resolutions, as evidenced by the strong 1080p performance. The data also shows that the scaling is not linear; the jump from 1440p to 4K is more punishing than from 1080p to 1440p. At Low settings, the trend is similar: 224 FPS at 1080p, 145 at 1440p, and 79 at 4K. The consistent pattern across settings confirms that the GPU’s rendering capabilities, particularly its memory bandwidth and compute power, are the primary constraint as pixel count increases. The CPU’s role is negligible in this game at these resolutions, as even at 4K Low, the system is still producing 79 FPS, which is well above what a CPU-bound system would show. This combination is clearly GPU-limited at 4K, but CPU-limited at 1080p, where the 224 FPS at Low settings suggests the CPU is preventing even higher frame rates.
