Doom

The AMD Ryzen 9 7900X paired with the NVIDIA GeForce RTX 4090 is an extreme high-end combination, and the measured results for Doom confirm this. Across all tested resolutions and presets, the average frame rates are exceptionally high, frequently exceeding the refresh rates of most monitors. The data shows a system that is not merely playable at maximum settings, but one that delivers performance headroom so vast it effectively removes the GPU as a bottleneck in this 2016 title.

Measured FPS Breakdown

The measured FPS data for this combination is striking, with no results falling below the playable threshold of 60 FPS. At 1920x1080, the lowest average recorded is 266.5 FPS on the Ultra preset. The scaling is linear across presets: Low yields an average of 441.2 FPS, Medium drops to 390.1 FPS, and High sees 329.3 FPS. This demonstrates that even at the highest settings, the system is pushing frame rates that are over four times the standard 60 FPS target.

Moving to 2560x1440, the performance remains remarkably high. The Ultra preset averages 173.9 FPS, while High produces 209.9 FPS. Medium and Low presets are even faster, averaging 254.1 FPS and 290 FPS respectively. The drop from 1080p to 1440p is noticeable but not drastic; the Ultra preset loses approximately 92.6 FPS, indicating that the GPU is beginning to take on more work, yet still has ample headroom.

At 3840x2160, the system finally encounters a workload that tempers its output, though it remains far above playable levels. The Ultra preset averages 96.8 FPS, which is still comfortably above 60 FPS. High settings average 113.6 FPS, Medium achieves 134.8 FPS, and Low reaches 155.5 FPS. The gap between Low and Ultra at 4K is 58.7 FPS, showing that the most demanding preset imposes a significant load on the RTX 4090, but the absolute performance remains excellent.

CPU and GPU Roles

The data reveals a clear shift in workload distribution as resolution increases. At 1920x1080, the frame rates are so high that the CPU likely becomes the primary limiting factor, especially when comparing the 441.2 FPS Low result to the 266.5 FPS Ultra result. The difference of 174.7 FPS between these presets suggests that while the GPU is still rendering more effects, the Ryzen 9 7900X’s 12 cores and 24 threads are being pushed to their limits to feed the GPU with draw calls and physics updates. The CPU's 3DMark single-thread score of 1093 and multi-thread score of 12536 indicate strong per-core performance that is essential for this type of workload.

At 2560x1440, the balance shifts slightly toward the GPU. The frame rate difference between Low (290 FPS) and Ultra (173.9 FPS) is 116.1 FPS, which is a smaller absolute gap than at 1080p. This indicates that the GPU is now spending more time on pixel shading and rasterization, making the gap between presets more about raw fill rate. The RTX 4090’s 82.58 TFLOPS FP32 performance and 1.01 TB/s memory bandwidth are clearly being utilized more effectively.

At 3840x2160, the GPU is unambiguously the dominant component. The frame rates across presets are tightly grouped relative to lower resolutions: the spread from Low (155.5 FPS) to Ultra (96.8 FPS) is 58.7 FPS. While the CPU still contributes, the pixel throughput demands of 4K resolution mean the graphics card’s 443.5 GPixel/s pixel rate is the decisive factor. The scaling between 1440p and 4K for the Ultra preset—a drop from 173.9 FPS to 96.8 FPS—further confirms that the GPU is approaching its limits, though it never reaches them.

Best Settings per Resolution

For every resolution tested, the most demanding preset—Ultra—remains at or above 60 FPS, making it the unequivocal best choice for visual fidelity. At 1920x1080, the Ultra preset averages 266.5 FPS, which is not only above the playable threshold but also high enough to take full advantage of a 240Hz monitor. This is the optimal setting for competitive play where frame rate is paramount.

At 2560x1440, Ultra settings deliver an average of 173.9 FPS. This is still exceptionally high, comfortably exceeding 144Hz refresh rates. The data suggests that users with high-refresh-rate QHD displays will have no reason to compromise on visual quality, as the system maintains fluidity even at the highest preset.

At 3840x2160, the Ultra preset averages 96.8 FPS. While this is lower than the lower resolutions, it remains well above the 60 FPS playable threshold. This makes Ultra settings the recommended choice for 4K gaming, as the system provides a smooth experience without requiring any reduction in graphical detail. The 96.8 FPS average is a strong result for a 4K resolution, which is typically the most demanding scenario.

How This Combo Ranks

According to the data, this CPU and GPU combination ranks 83rd out of 3712 tested combos for Doom. This places it in the top 2.2% of all configurations, a position that reflects its extraordinary performance. The rank is likely influenced by the fact that many of the 3712 combos include less powerful CPUs or GPUs, but it also suggests that there are a handful of configurations that can exceed these frame rates, likely involving even more recent flagship hardware.

The high rank is consistent with the measured FPS data. The RTX 4090’s percentile rank of 88 among all GPUs, combined with the Ryzen 9 7900X’s percentile rank of 91 among all CPUs, indicates that this pairing is at the apex of consumer hardware. The combo’s 83rd place ranking out of 3712 is a logical outcome of two components that are both in the top 12% of their respective categories.

Similar Performance Alternatives

The nearestRivals data provides insight into what other CPUs and GPUs would deliver similar performance. For the CPU, the AMD Ryzen 9 7900X is closely matched by the AMD EPYC 7313P, which has an average benchmark score of 53206, a mere 0.2% lower. The Intel Xeon Phi 7290 is 0.3% faster, while the Intel Xeon 634 is 0.6% slower. The Intel Core i7-14700F is the closest consumer alternative, being 0.6% faster. These small deltaPct values mean that swapping the 7900X for any of these would result in nearly identical frame rates in Doom, as the game is not heavily CPU-bound at higher resolutions.

For the GPU, the RTX 4090’s nearest rival is the Intel Arc Pro A60, which has an identical average score (0% delta). The AMD Radeon Pro Vega 48 is 0.3% slower, and the AMD Radeon PRO V710 is 2.9% slower. The AMD Radeon Pro W6600M is 2.5% faster. These deltas are minor, suggesting that a system with one of these GPUs would produce very similar FPS numbers in Doom, though the professional-grade nature of these alternatives may affect other aspects of gaming performance.

The Verdict

Yes, this PC can run Doom with exceptional proficiency. The verdictByResolution data confirms that all playable settings—Low, Medium, High, and Ultra—are available at every resolution tested. At 3840x2160, the best settings are Ultra, with an average FPS of 96.8, which clears the 60 FPS threshold by a wide margin. At 2560x1440, Ultra averages 173.9 FPS, and at 1920x1080, Ultra averages 266.5 FPS.

The system is not only capable of running the game but does so with such headroom that it can handle future titles or higher refresh rate displays without issue. The RTX 4090’s 24 GB of GDDR6X memory and 1.01 TB/s bandwidth are more than sufficient for Doom’s textures and effects, while the Ryzen 9 7900X’s 12 cores ensure that even the most complex scenes are processed without slowdown. In short, this combination is overkill for Doom, but it is a comfortable overkill that provides a flawless experience.
