Doom

The AMD Radeon RX 7900M paired with the Intel Core Ultra 7 155H delivers a high-performance gaming experience in Doom, with measured results indicating that the combination is capable of handling the game at high frame rates across all tested resolutions. The data set provides a clear picture of how the system scales from 1080p to 4K, revealing a GPU-bound workload at higher resolutions and a system that remains fluid even under maximum settings. This analysis walks through the measured FPS data, the combo's standing among other tested configurations, and the specific roles played by the GPU and CPU in producing these results.

Resolution Scaling

The measured FPS data shows a predictable decline in performance as resolution increases, which is typical for a GPU-intensive title like Doom. At 1080p with Low settings, the combo achieves an average of 258 FPS. Moving to 1440p at the same Low preset, the average drops to 167 FPS, a reduction of 91 FPS. At 4K with Low settings, the average further decreases to 90 FPS. This pattern indicates that the Radeon RX 7900M is the primary limiting factor as pixel count rises, with the CPU providing sufficient headroom to feed the GPU at lower resolutions.

The scaling from Medium to High settings at each resolution also highlights the GPU's workload. At 1080p, the drop from Medium (225 FPS) to High (190 FPS) is 35 FPS, while at 1440p the same settings transition results in a 22 FPS drop (145 to 123 FPS). At 4K, the gap narrows to 12 FPS (79 to 67 FPS), suggesting that at higher resolutions, the GPU is already saturated and the incremental cost of the High preset becomes less pronounced relative to the overall frame rate. The Ultra preset shows the most significant impact, with 4K Ultra averaging only 54 FPS, a 36 FPS drop from the High preset at the same resolution.

The data suggests that at 1080p, the system is likely not fully GPU-bound, as the frame rates are extremely high across all settings. However, the gap between Low and Ultra at 1080p (258 vs 155 FPS) is substantial, indicating that the GPU still carries most of the rendering load. At 4K, the system is clearly GPU-bound, with even the Low preset (90 FPS) requiring significant effort from the RX 7900M. The minimum FPS data, available for Medium settings, shows 191 FPS at 1080p, 124 FPS at 1440p, and 67 FPS at 4K, which aligns with the average FPS trends and indicates consistent frame pacing without severe drops.

How This Combo Ranks

The combination of the Intel Core Ultra 7 155H and AMD Radeon RX 7900M ranks 1226 out of 2930 tested combos in Doom. This places the system in the upper half of all configurations, though not at the very top. The percentile data for the individual components provides context: the GPU sits in the 94th percentile among all GPUs, while the CPU is in the 83rd percentile among all CPUs. This suggests that the GPU is a stronger performer relative to its peers than the CPU, which is consistent with the resolution scaling behavior observed.

The combo's rank of 1226 out of 2930 indicates that there are many other systems that deliver higher frame rates in Doom, but also a large number that perform worse. Given the GPU's high percentile ranking, the result is likely influenced by the CPU's position. The CPU's nearest rivals in average benchmark score include the Intel Core i5-14600T (score 32707, delta 0%), AMD Ryzen AI 7 PRO 360 (score 32662, delta 0.1%), AMD Ryzen 5 7400F (score 32750, delta -0.2%), and AMD Ryzen 7 PRO 6850H (score 32812, delta -0.4%). These deltas are minimal, indicating that the Core Ultra 7 155H performs within a narrow band of comparable processors, which likely translates to similar gaming outcomes when paired with the same GPU.

In the context of the game's FPS data, the combo's rank is reasonable given that Doom is known for being well-optimized. The measured frame rates at 1440p High (123 FPS) and 4K High (67 FPS) suggest that the system is competitive, but the rank of 1226 implies that faster configurations exist. The GPU's nearest rivals include the AMD Radeon Pro VII (score 97131, delta 0.4%), NVIDIA Quadro RTX 6000 (score 101872, delta -4.3%), AMD Radeon Instinct MI60 (score 92466, delta 5.4%), and NVIDIA RTX A4500 (score 91671, delta 6.3%). The RX 7900M outperforms most of these in average benchmark score, but the Quadro RTX 6000 holds a 4.3% lead, which could explain why some combos rank higher.

GPU Role

The AMD Radeon RX 7900M is a decisive factor in this combo's Doom performance, given its 94th percentile ranking among all GPUs. The GPU features 16 GB of GDDR6 memory on a 256-bit bus, providing 576.0 GB/s of bandwidth. This memory capacity and bandwidth are sufficient for the demands of Doom, even at 4K resolution, as evidenced by the playable frame rates at High settings. The GPU's clocks are listed with a base of 1825 MHz and a boost of 2090 MHz, with memory running at 2250 MHz (18 Gbps effective). These clock speeds, combined with 4608 shading units, 288 texture mapping units, and 192 raster output units, contribute to the high pixel rate of 401.3 GPixel/s and texture rate of 601.9 GTexel/s.

The RDNA 3.0 architecture, built on a 5 nm process by TSMC, includes 72 ray tracing cores and delivers 38.52 TFLOPS of FP32 performance. In Doom, which is not heavily ray-traced, the raw rasterization power is more relevant, and the data shows that the GPU handles the game well. At 1080p Low, the GPU can push 258 FPS, which is far beyond the refresh rate of most displays. At 4K Ultra, the average of 54 FPS is still playable, but the drop from the High preset suggests that the GPU's limits are reached at the highest settings and resolution.

The GPU's benchmark scores further contextualize its performance. In 3DMark Steel Nomad DX12, it scores 4201, while Geekbench OpenCL and Vulkan scores are 129499 and 158760, respectively. These scores align with the GPU's high percentile ranking and support the measured FPS results in Doom. The GPU's TDP is listed at 180 W, which is typical for a high-performance mobile part, and it uses a PCIe 4.0 x16 interface. The lack of a launch MSRP for the GPU means no pricing information is available, but the performance metrics stand on their own.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend on the target resolution and desired frame rate. At 1080p, the Ultra preset delivers an average of 155 FPS, which is excellent for fast-paced FPS gameplay. The data shows that even the most demanding settings are comfortably handled at this resolution, with no setting dropping below 155 FPS. For players with high-refresh-rate monitors (e.g., 144 Hz), the Ultra preset is the best choice, as it provides a smooth experience without sacrificing visual quality.

At 1440p, the Ultra preset averages 100 FPS, which is still very playable and suitable for most competitive scenarios. However, the High preset at 1440p sees a significant jump to 123 FPS, offering a better balance if frame rate is prioritized over maximum visual fidelity. The Medium preset at 1440p (145 FPS) provides an even higher frame rate with only a modest reduction in settings. Given the data, the High preset at 1440p is recommended for a mix of quality and performance, while Ultra is viable for those who prefer visuals.

At 4K, the situation changes. The Ultra preset averages only 54 FPS, which is on the edge of playability for a fast-paced game. The High preset at 4K improves this to 67 FPS, which is more acceptable, but still not ideal for high-refresh displays. The Medium preset at 4K (79 FPS) offers the best balance, providing a smooth experience while maintaining decent visual fidelity. The Low preset at 4K (90 FPS) is the only option that consistently exceeds 90 FPS, but it sacrifices significant graphical detail. For 4K gaming, the Medium preset is the recommended starting point, with High being viable for those who prefer quality over frame rate.

CPU Role

The Intel Core Ultra 7 155H plays a supporting role in this combo's Doom performance, as evidenced by the resolution scaling data. The CPU features 16 cores and 22 threads, with a base clock of 3.80 GHz and a boost clock of 4.80 GHz. Its cache hierarchy includes 112 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3 cache. This configuration is built on Intel's Meteor Lake architecture using a 7 nm process, and it supports DDR5 memory with a dual-channel bus providing 89.6 GB/s of bandwidth.

In Doom, the CPU's role is to feed the GPU with draw calls and game logic, and the data suggests it does so effectively. At 1080p Low, the system reaches 258 FPS, which is a very high frame rate that would stress many CPUs. The fact that the CPU can maintain this level of performance indicates that its 22 threads and high boost clock are sufficient for the game's demands. The CPU's benchmark scores support this, with a Cinebench R23 multi-core score of 15028 and a single-core score of 1743. The Passmark multi-thread score of 24873 and single-thread score of 3468 further confirm its capability.

The CPU's percentile ranking of 83 places it above average, but below the GPU's 94th percentile. This gap suggests that while the CPU is not the bottleneck in Doom, it may limit performance in scenarios where frame rates are extremely high, such as at 1080p Low. However, the measured data shows that even at 1080p, the system achieves 258 FPS, which is beyond the refresh rate of most gaming monitors. The CPU's nearest rivals, such as the Intel Core i5-14600T and AMD Ryzen 7 PRO 6850H, have nearly identical average benchmark scores, indicating that swapping the CPU for one of these would likely result in similar Doom performance.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across three resolutions and four settings presets. At 1920x1080, the Low preset delivers an average of 258 FPS, which is the highest measured in the entire dataset. The Medium preset at the same resolution averages 225 FPS, with a minimum of 191 FPS and a maximum of 258 FPS. High settings at 1080p yield an average of 190 FPS, while Ultra settings drop to 155 FPS. These numbers indicate that the system is not CPU-limited at 1080p, as even the most demanding preset maintains a high frame rate.

At 2560x1440, the performance scales down as expected. Low settings average 167 FPS, Medium averages 145 FPS with a minimum of 124 FPS and a maximum of 167 FPS, High averages 123 FPS, and Ultra averages 100 FPS. The transition from 1080p to 1440p results in roughly a 35-40% reduction in average FPS across all settings, which is consistent with the increased pixel count. The minimum FPS at Medium (124 FPS) suggests that the system maintains smooth performance even in demanding scenes.

At 3840x2160, the frame rates drop further. Low settings average 90 FPS, Medium averages 79 FPS with a minimum of 67 FPS and a maximum of 91 FPS, High averages 67 FPS, and Ultra averages 54 FPS. The 4K data shows that the system is GPU-bound, as the frame rates are significantly lower than at 1440p. The minimum FPS at Medium (67 FPS) is equal to the average FPS at High, indicating that the High preset at 4K is more demanding than Medium. Overall, the measured FPS breakdown shows a system that excels at 1080p and 1440p, with 4K performance being acceptable for less demanding settings.
