Doom

The AMD Ryzen 7 9800X3D and NVIDIA GeForce RTX 5070 Ti pairing delivers exceptional performance in Doom, with the data showing a combo that prioritizes high refresh rates at any resolution. The measured results across three resolutions and four settings presets reveal a system where the GPU is the primary scaling factor, but the CPU’s strong single-threaded capabilities keep frame rates consistently high.

Resolution Scaling

The frame rate drop from 1080p to 4K follows a clear pattern that points directly at the GPU as the limiting component. At Ultra settings, the average FPS falls from 230.9 at 1920x1080 to 150.8 at 2560x1440, a reduction of 80.1 FPS, and then further down to 79.1 at 3840x2160. This represents a 65.7% drop from 1080p to 4K, which is a substantial scaling loss typical of a GPU-bound scenario where pixel count drives the workload.

The Low settings preset tells a slightly different story. At 1920x1080, the combo achieves 382.1 FPS, which drops to 248.6 at 2560x1440 and then to 134.4 at 4K. The percentage drop from 1080p to 4K here is 64.8%, nearly identical to the Ultra preset. This consistency across presets confirms that the RTX 5070 Ti’s rendering throughput is the dominant factor, not the CPU. Even at Low settings, the GPU is still the bottleneck because the CPU can feed frames faster than the GPU can render them.

The Medium and High presets show the same scaling behavior. Medium goes from 333.2 FPS at 1080p to 218.7 at 1440p and 116.0 at 4K. High drops from 285.9 to 182.5 and then 102.0. The 4K results across all presets — 79.1 to 134.4 FPS — indicate that the RTX 5070 Ti’s 16 GB of GDDR7 memory and 896.0 GB/s bandwidth are sufficient to keep the frame buffer fed, but the raw shading power (43.94 TFLOPS FP32) becomes the limiting factor as resolution increases.

Settings Recommendations

The data shows that High settings provide the most balanced experience across all three resolutions. At 1920x1080, High yields 285.9 FPS, which is 54.1 FPS lower than Low but still far above the refresh rates of most monitors. The jump from High to Ultra costs 55.0 FPS at 1080p, which is a significant penalty for the visual fidelity gain. At 2560x1440, High delivers 182.5 FPS, comfortably above 144 Hz displays, while Ultra drops to 150.8, still playable but with less headroom.

For 4K, High is the recommended preset. The 102.0 FPS average at 3840x2160 is above the 60 FPS threshold for smooth gameplay, and it is 22.9 FPS higher than Ultra’s 79.1. Medium offers 116.0 FPS at 4K, which is only 14.0 FPS more than High, making the visual quality trade-off less worthwhile. Low at 4K produces 134.4 FPS, but the graphical compromises are likely too severe for a game like Doom that benefits from high detail.

The measured data indicates that High is the sweet spot because it maintains high frame rates without the steep performance cost of Ultra. At 1080p, even Ultra is viable at 230.9 FPS, but the 55.0 FPS gap between High and Ultra suggests that the extra settings do not justify the frame rate loss for most users. For competitive play, Low at 1080p (382.1 FPS) or 1440p (248.6 FPS) is the clear choice, but for general play, High offers the best combination of visual quality and performance.

CPU Role

The AMD Ryzen 7 9800X3D’s 8 cores and 16 threads, combined with a 96 MB shared L3 cache, are more than sufficient for Doom. The game’s engine does not appear to be heavily multi-threaded based on the frame rate data, but the CPU’s single-thread performance is critical. The 3DMark single-thread score of 1212 and the Cinebench R23 single-core score of 4800 indicate strong per-core performance that prevents CPU bottlenecks at high frame rates.

The boost clock of 5.20 GHz and base clock of 4.70 GHz provide the clock speed headroom needed for this type of workload. At 1080p Low, the combo reaches 382.1 FPS, which is only possible if the CPU can issue draw calls faster than the GPU can render them. The 3DMark 2-thread score of 2394 and 4-thread score of 4669 suggest that the CPU excels in lightly threaded scenarios, which aligns with Doom’s engine behavior.

The 3DMark max-thread score of 10067 versus the 16-thread score of 10081 shows that the CPU scales well up to 16 threads, but the game likely does not utilize all of them. The PassMark multi-thread score of 40009 and single-thread score of 4430 confirm that the CPU has both high throughput and high per-core efficiency. This combination is why the frame rates remain high even at 1440p, where the CPU still has to keep up with the GPU’s output.

How This Combo Ranks

The combo ranks 133rd out of 1681 tested combinations in Doom, placing it in the top 8% of all systems tested. This ranking is driven primarily by the RTX 5070 Ti’s GPU compute performance, which has an average benchmark score of 52086 and sits at the 87th percentile of all GPUs. The CPU, with an average benchmark score of 37780 and the 90th percentile, provides the necessary foundation without being a limiting factor.

The GPU’s nearest rivals show a tight cluster: the RTX 4080 has a deltaPct of 0, meaning identical performance, while the AMD Radeon RX 7700S is 0.8% slower and the AMD Radeon Pro W6600M is 2.5% slower. This indicates that the RTX 5070 Ti is well-matched against previous generation high-end cards. The CPU’s nearest rivals, such as the Intel Core i9-13900HK (0.6% slower) and Intel Core i5-13600KF (0.7% slower), also show that the 9800X3D is competitive with top-tier Intel chips.

The combination’s rank of 133 out of 1681 is respectable, but the data shows that the GPU is the more influential component for this game. The RTX 5070 Ti’s 87th percentile GPU ranking is slightly lower than the CPU’s 90th percentile, suggesting that the GPU is the more common bottleneck. However, the combo’s high absolute frame rates at all resolutions indicate that this pairing is well-balanced for Doom.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates. Low settings produce 382.1 FPS, Medium drops to 333.2 FPS, High yields 285.9 FPS, and Ultra settles at 230.9 FPS. The gap between Low and Ultra is 151.2 FPS, showing a wide range of performance depending on visual fidelity.

At 2560x1440, Low achieves 248.6 FPS, Medium 218.7 FPS, High 182.5 FPS, and Ultra 150.8 FPS. The difference between Low and Ultra is 97.8 FPS, which is a smaller absolute gap than at 1080p but still significant. The High preset at 182.5 FPS is the most balanced for this resolution.

At 3840x2160, Low produces 134.4 FPS, Medium 116.0 FPS, High 102.0 FPS, and Ultra 79.1 FPS. The drop from Low to Ultra is 55.3 FPS, indicating that the GPU is heavily taxed at this resolution. High is the recommended preset here, as it stays above 100 FPS while Ultra falls below 80 FPS.

The data across all resolutions shows a consistent pattern: Low always delivers 30-40% more FPS than Ultra, and High is always within 20-30% of Low. This suggests that the game’s Ultra preset imposes a heavy rendering cost that is not proportional to the visual improvements, while High provides a better performance-to-quality ratio. The RTX 5070 Ti’s 43.94 TFLOPS FP32 compute and 96 ROPs are the key specifications driving these results, with the CPU’s high single-thread performance ensuring no bottleneck at any settings combination.
