Doom

The AMD Ryzen 9 8945HX paired with the NVIDIA GeForce RTX 4080 Mobile delivers a dominant performance profile in Doom, securing the 1222nd position out of 3712 tested combinations. This places the combo in the 67th percentile of all tested systems, a strong result that reflects the high-end nature of both primary components. The data indicates that this pairing is well-balanced for the game, with the CPU’s substantial multi-threaded capability complementing the GPU’s high frame-rate output. While not the absolute top-tier configuration, this combo consistently produces frame rates that far exceed the 60 FPS threshold, even at the most demanding settings and resolutions available in the test suite.

How This Combo Ranks

The comboRankInGame of 1222 out of 3712 places this system in the upper third of all tested configurations for Doom. This is a strong showing, indicative of a hardware pairing that is more than sufficient for the game's engine. The ranking reflects a performance level that is competitive with a wide array of other high-end desktop and mobile parts, suggesting that users of this specific laptop configuration will experience no significant performance bottlenecks. The position is not at the very apex of the leaderboard, leaving headroom for more powerful, likely desktop-class, components, but it firmly establishes this combo as a high-performance solution for this title.

The percentile placement is more telling when considering the individual components. The CPU sits in the 95th percentile of all CPUs, while the GPU is in the 81st percentile of all GPUs. This discrepancy suggests that the processor is relatively more powerful than the graphics card when compared to their respective pools of peers. In the context of Doom, a game known for its scalability, this means the CPU is likely never the limiting factor. The system’s overall rank is therefore primarily dictated by the GPU’s capabilities, which are substantial. The data shows a system that is ready for high-refresh-rate gaming without compromise.

Settings Recommendations

Benchmark results indicate that the optimal experience hinges on the user's priority: maximum frame rate or maximum visual fidelity. The measured FPS data clearly shows that the "Ultra" preset is entirely playable, with an average of 173 FPS at 1080p. This is the best choice for users with high-refresh-rate displays who want the game's highest visual quality without sacrificing smoothness. The performance headroom is significant, as even at 4K, the "Ultra" preset maintains an average of 61 FPS, which is right at the threshold for standard 60Hz displays.

For competitive play where frame rate is paramount, the "Low" preset offers the highest possible performance, reaching an average of 288 FPS at 1080p and 101 FPS at 4K. However, the "Medium" preset provides a compelling middle ground. At 1080p, it delivers 251 FPS, which is only a 13% reduction from "Low" but likely offers a noticeable improvement in visual quality. The data suggests that "Medium" at 1080p or 1440p is the sweet spot for high-refresh-rate gaming, providing a significant frame rate buffer while still maintaining a more detailed scene. The "High" preset, while performing well, offers diminishing returns in frame rate compared to "Medium" at higher resolutions.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals the expected trend of a GPU-bound workload. At "Ultra" settings, the average frame rate drops from 173 FPS at 1080p to 112 FPS at 1440p, a 35% reduction, and then to 61 FPS at 4K, a further 46% reduction from 1440p. This steep decline is characteristic of a game that is heavily dependent on pixel fill-rate and GPU compute at higher resolutions. The RTX 4080 Mobile's 12 GB of VRAM and 432.0 GB/s of memory bandwidth are sufficient to handle the increased data load, but the raw processing power is the limiting factor as resolution scales.

The scaling pattern is similar across all settings, but the relative drop is more pronounced at the lower settings. For instance, at "Low" settings, the frame rate drops from 288 FPS at 1080p to 186 FPS at 1440p (a 35% drop) and then to 101 FPS at 4K (a 46% drop from 1440p). This consistent pattern confirms that the GPU is the primary bottleneck in this configuration for this game. The CPU, with its 16 cores and 32 threads, has ample headroom to feed the GPU at all resolutions, as evidenced by the high frame rates at 1080p. The data shows that the RTX 4080 Mobile is the component that dictates the performance ceiling as resolution increases.

GPU Role

The NVIDIA GeForce RTX 4080 Mobile is the central component for determining frame rates in Doom, as evidenced by the resolution scaling data. Its 12 GB of GDDR6 memory on a 192-bit bus provides a 432.0 GB/s memory bandwidth, which is ample for the game's textures and assets at 4K. The GPU's 7424 shading units and 80 ROPs are responsible for the raw pixel throughput, and the data shows they are pushed hard at higher resolutions. The boost clock of 1665 MHz, while not the highest in the product stack, allows the card to sustain high performance in this title.

The GPU's performance is further contextualized by its benchmark scores. It achieves a passmark_g3d score of 24926, placing it in the 81st percentile of all GPUs. Its nearest rivals in the database include the NVIDIA GeForce RTX 5080 Mobile and the NVIDIA GeForce RTX 4070, indicating that this mobile part is competitive with newer and desktop variants. The data shows the GPU is well-suited for high-refresh-rate 1080p and 1440p gaming and can handle 4K at playable frame rates, making it the key driver of the system's overall ranking.

CPU Role

The AMD Ryzen 9 8945HX plays a supporting but critical role in this combo, ensuring the GPU is never starved of data. With 16 cores and 32 threads based on the Zen 4 architecture, the CPU provides immense multi-threaded throughput, as shown by its passmark_multithread score of 51405. Its single-thread performance, measured at 3907 in passmark_singlethread, is also excellent, which is crucial for game logic and physics. The high boost clock of 5.40 GHz ensures that single-core tasks are handled with minimal latency.

The CPU's performance, which places it in the 95th percentile of all CPUs, is significantly ahead of the GPU's relative standing. Its nearest rivals, such as the AMD Ryzen 9 9950X3D and Intel Core Ultra 9 285HX, are also top-tier processors, underscoring its high-end positioning. In Doom, the data indicates that the CPU is not a bottleneck. The consistent frame rate scaling with resolution changes is a clear indicator that the CPU can maintain its frame generation duties even when the GPU's workload increases significantly, allowing the RTX 4080 Mobile to perform to its full potential.

Measured FPS Breakdown
